XBOX360 handle of the previous generation, that handles the most worthy of esteem is it left and right joystick, great location; at the same time also more comfortable keys. But its biggest drawback is its side there are only two trigger button, and the remaining two are placed to the right half of the handle, so press the key sequence is in trouble. At the same time, you must also have the support of wiring (the good news is that it is still not out of print, but estimated cash will not be too much). Price: original handle 150-160 per transfer line 20.
Cold front handle Logitech ChillStream. .
Logitech ChillStream May 2007 the most eye-catching handles. Because the handle was just listed only in Europe and the United States, the official Chinese name not named, I venture to give it a name to replace it, huh, huh. Logitech ChillStream/cold front handle (ice front), which handles most major characteristic is the handle on both sides there are two outlet, through the principle of blowing out of the hand not sweating too much (no change out of hot sweat sweating, hehe). . It is learned, PS3 version is a black handle, PC version is silver white handle. Currently Overseas Price: 40 U.S. dollars, EBAY price 32 U.S. dollars. Domestic current spot less, work package handle excl 288 (Dongguan production), box 340 (Dongguan production), the absence of listing, the current warranty or a blank, but the problem could be returned to original seller warranty promise . .

For businessmen who spend the off-season is always the most tough, so this time is seems to have deserted store, and even the leader in home appliance industry in Nanjing Suning Electric is no exception. Suning into the main store at Huaihai Road, past the crowded scene no longer exists in India and into your eyes is the salesman looked at each other. But when I went to Sony Ericsson counters when they received a pleasant surprise, Sony Ericsson has just announced four new machines in a, S500 real machine appeared in front of me. Sony Ericsson, according to on-site staff that this was a prototype project, price not yet determined. Hurry to pre-training recently, so it appears from the market not far away. .
Home standby screen is Sony Ericsson's traditional style, and menu options is great. However it was off to Sony Ericsson staff, the final retail version of the system interface will make the appropriate adjustments, to more than engineering prototype now cool. The screen configuration, 26 million colors TFT screen, QVGA resolution, 2-inch viewable area display effect is quite good.
Camera at the back cover, 2 million pixels are the mainstream of the current configuration. .
We don't put the rear fuselage and the navigation buttons at the bottom of the matrix as the speaker sound holes, Oh, this is just a decoration. Into this design not only has a very good visual effects, and also plays the role of non-slip method. In addition, the camera below the blank region also printed with irises, formally adopted little before the S500 dressed more beautiful.
From the bottom of the screen function key area of the design is easy to see the shadow of that year S700, but on the basis of the original key of a key multi-access and application manager. Furthermore, S500 speaker did not appear on the back of the fuselage, but the navigation keys are hidden in the bottom of this design is rare in the past. According to measured after several MP3 ringtones and found that the speaker has good volume, and the expression of sound is very commendable. .
As a positioning fashion phone, then at least some naturally into the cool of the element. From the above figure is not difficult to see that opened the door and slide, the fuselage sides will have blue LED lights are lit at night is sure to win you a lot of return rate.
M2 card slot is located on the slide to the top, and with a dust cover. .
The design of the numeric keypad is in and out, not only flavour with full metal, while at the same time feel also very good.
Open the camera mode, the screen view finder, real-time scene, S500 camera quite amazing expression. .

NFS PRO STREET first experience.
We are fortunate to experience the "Need for Speed street-hegemony" ALPHA demo, I see it, this new work and any predecessor have somewhat different. If you think this is "Need for Speed 10> if the enhanced version of You're wrong! Professional circuit to provide a new driving experience, games, models and a variety of new features. EA would like to make clear to Need for Speed series to new heights, from happiness is the most significant change in cancellation of the open world, completely in a closed circuit. EA, extensive research, make these race track completely true, where there are no rules at all, of course, is no longer there hate the police and passing cars. .。 The most important new features basically includes: car crash systems, physical characteristics and smoke.
Car crash the system:. .
The streets of Kings "car crash system may interfere with your difficult to finish the game, just like the front of the police and the passing vehicles. Damage is the highlight of this, you should always be careful not to ruin your car, be aware that car is expensive, but you cannot use the repairing of vehicles. The so-called damage, not just scratches or concave, and this time you may not be able to complete the game and because complete waste of your vehicle. According to my observation, the damage model is actually done very well.. than I've seen real Dora! bumper and tire can come off, Windows can shred roof you can try to fly.
Different materials (metal, glass, plastic, or carbon alloy) and there may be scratches, damage, or even broken. All of the damage are calculated separately, so do not always look the same, sometimes depending on the speed you hit the wall size. The most important thing, car damage system will affect your driving performance. The more bad car driven to the more slowly, if installed too many times, then, GAME OVER! View of spending a lot of repairs, you probably will most of the money China in the modified engine and internal parts, rather than spend shell mend them. But this is still street race, so if you car has a well-known NB, than have a new car without scratches cool! . .
Location:..
"Street hegemony" of the track exist in different locations, and these places are real. EA spent a lot of effort to do these as much as possible the real track. Players need to travel around the world to attend events held around the world. As events have different sponsors, so the style is different. Different races and even the style of music is different. .
Game mode:.
There are 4 game modes: grip races, drift races, straight-line acceleration, and the "speed challenge." Players can be different debugging their car models to suit different game. Grip race is the race before counting laps; drift race may be 10 generations in the physical properties and different, not so easy to drift pull. To enhance the fly sexual, EA set up a "support system" to help the player operation of the vehicle.。 But be careful to turn this speed while driving is very dangerous.
NFS is to use the traditional authority of the car manufacturers, this is the same, but the number to more than any predecessor. I am sorry I can not reveal the list of those cars here, but be sure to include the 26 manufacturers. Among them, eight "super sports car", you can moved them to the speed; if you do not like, you can choose low-end cars, these cars can be a modified and better cars to compete. .
User-defined (customization).
User-defined "street hegemony" of a major component. We know you may come and go in 10 agents to set the appearance of the car; but this time you can spray the car almost every place. The most interesting thing, spraying will affect your car's performance, based on the new physics engine, exterior of each vehicle will affect vehicle performance, so you should get some consideration when decorating. This EA has designed a wind tunnel, so that you test the suitability of the new exterior. This is a cool design, I like in addition to exterior changes, you need to debug performance. And exterior, like performance tuning, fine Dora than before. For a second wind, EA designed the different debug levels.。 If you want more in depth, will find almost everything can be changed — the engine parts, brakes, tire. 90 + separate accessory slots and 30 + debug selection. You can test your car DYNO, resulting in the chart, depending on the feedback report. Based on the focus enables users to customize, EA introduced new features — the "blueprint" for blueprint is your storage conversion programme, you can always reference and any car.
Image:. .
I just play with the ALPHA version, so it's not a good comment images. But I can tell you that the image is quite small. Racing more real than 10 generations. Each car has a 15000 to 20000 polygon, vehicle reflective material based on different are different, and destruction system is also very fine, you will find that you are driving a car, not a a rushes this great new feature is a haze effect! almost all of the racing game, play ground tire smoke look rough. . .0. PC system requirements is far greater than 10 generations, or any other racing game now, of course, specific requests for further information. .
General assessment:.
Tell the truth I heard "street hegemony" did not open and surprise the world, "street hegemony" means the road is not open completely in a closed circuit in race. But EA confirmed the "street hegemony" and NASCAR, F1 has nothing to do. "Street hegemony" is not a pure simulation game, or see ordinary cars, street style, or wild game. When I saw the real damage, the high degree of freedom converted, no police and traffic, I do not doubt this for the water products, and I'm looking forward to the "street hegemony" to come. .

Sony has sold for the mid-ear products, MDR-E888 is undoubtedly the most popular, and its quality is also widely praised by consumers, the main reason lies in its use of bio-diaphragm, currently on the market Packed MDR-E888 offer are around 300 yuan. .
However, in spite of the fact that AMD has acquired ATI, but putting their relationship to adjust the product development plans and cycle back off a lot of time, at the end of last year, with the support of the launch of the first generation of DirectX10 graphics chip postponed until May. While AMD next-generation development code-named Rx6xx display core eventually being named the Radeon HD 2000 series, and the end of these products, AMD has really involved in the field of independent graphics. . .
Despite these troubles, AMD R6xx has become the history behind NVIDIA corresponding product times up to the first generation product, but now I cannot say that AMD is disadvantageous, because Vista operating system, January 31, listing, and based on DirectX10 games so far a no, that is to say, at least in the applications and experience the AMD does not lag behind and what those early purchase NVIDIA DirectX10 graphics card products to also does not support DirectX10 but because G8x prematurely related experience.
. The RV610/RV630 as opening a new 65nm process, in production, they also encountered some problems and therefore can not be extended naturally to avoid listing, but this has not much of a problem, Radeon HD2400/HD2600 display card will be out in the middle of next month as scheduled goods. The reason why AMD courage without fear, mainly because the current application based on DirectX10 not, therefore, AMD had enough time to layout product. .
For next-generation Radeon HD2000 series graphics card, AMD began a Prefect 10 slogan from the literal meaning, AMD believes that their products are perfect, then AMD how to interpret their own product?.
1. . Full support for DX10 games. .
2. HD experience.
3. .'s Leading technology (including Vista good support, 65nm process, and lower power consumption). .
For the Radeon HD2000, AMD unveils products, namely: Radeon HD 2400Pro, Radeon HD 2400XT, Radeon HD 2600Pro, Radeon HD 2600XT and Radeon HD 2900XT. . .
And that all products of nature is the most high-end Radeon R600 core based HD 2900XT, R600 consolidation up to 7 million transistors using 80nm process, R600 itself carrying up to 320 stream processors, this is what drove G80 128/96 stream processors more. . .
In the video memory configurations, the Radeon HD 2900XT GDDR3 particles in a still, but graphics memory bandwidth, memory, its theoretical 512bit bandwidth of up to 106GB/s of bandwidth channel, this is the world's first civilian use 512bit video memory your video card. Other aspects, HD 2900XT integrates digital audio and HDMI output features, and NVIDIA's GeForce 8800 graphics card then shameless capability, integrated HDMI, users can more convenient output HDMI video and audio to HDMI audio video device. . .
In fact, purely from a technical specifications recital AMD R600 with previous generations of the original difference, but judging from the interior design with the original R600 R5xx between design has almost no relationship because import DirectX10 support so that those designs were originally has been unable to respond. . .
R600 in such design idea, its most distinctive feature is the increase in the number of Shader units, while the texture unit is significantly elevated, R600 for Shader processing stream processor is reached 320, while the texture unit has only 32, this difference is very large.
In DirectX10, the biggest innovation is the introduction of the support of the Unified Shader Architecture, the traditional DirectX9, its use separate vertex Shader and Pixel SHader to deal with vertex and pixel data, starting with geometry vertex processing, and then generate the geometric basic graphic elements, including point, line, and triangle, etc., and then entered Pixel Shader pixel processing unit and then proceed to ROP grating treatment for mixed, Z buffer, and anti-aliasing and other treatment, the ultimate effect of generating the display to enter local memory, into the output section. .
The traditional architecture of DirectX 9, its strict GPU provides for Vertex Shader and Pixel Shader units, above the Photo column, grey, red, on behalf of the idle time on behalf of the processing time. Look at the upper-left corner of the picture, in this scenario, the game is mainly for the construction of a geometry, you need a large number of Vertex Shader and Pixel Shader operations, most of their time idle; bottom left of the picture we can see that the water treatment unit depends primarily on the Pixel Shader, the Vertex Shader units here and an idle state. . .
And accompanied by technical upgrading, the current GPU already can consolidate more Shader units, and the introduction of the unified rendering schema, allowing any Shader unit can handle Vertex Shader or Pixel Shader data. Making resource is no longer waste, from the top of the performance can be seen on the right side of the picture, use the unified rendering schema, all Shader units are in working condition, caused by the waste of resources will be very rare. . .
R600 core schema is mainly divided into directive processor, Hyper-Threading equipped engines, assigned processor, calculated cells, texture unit and cache, memory read/write caching and streaming output buffers, render output, render the backend (REB) several major parts. Directive processor and equipment engine is responsible for sending the instruction and the primary information collection, compilation, then that is the first major consolidated schema processing, that is hyper-threading assigned processor. . Distribution on the use of hyperthreading and AMD processors to carry out the control flow processor operation mode. .
Hyper-Threading processor, various assigned Shader operations data actually were separated. From Setup to assign processor Engine, various data first be divided into three, including the VS, PS and GS, different data classification will be to sort the data flow of a data flow, data flow, the second, third ... and then waiting for the fed to the specific flow processing unit for processing.
In the data flow and flow between the processing units, as well as a "arbiter" (arbiter) of the unit in operation, its basic function is to allow data flow to the shortest waiting time into the stream processing unit, the central idea in this under the guidance of "arbiter" general will always look first into the sort of data flow, giving priority to their stream processing units into the calculation, so that different data classification can be calculated to ensure a balanced and will not delay the earlier data in a timely manner calculation. After calculating the arbitration device, the data stream will flow into the SIMD processing units lined up, one by one operation. .
Assigned in hyper-threading processor also has specialized vertex and texture arbitrator, you can let some data directly into the vertex and texture units, so that some data no longer after Shader units, reducing stream processing unit is invalid. Hyper-Threading assigned processor also assigned exclusive stain, cache, so that a variety of data flow is always maintain high speed of the wait state, once inside the operation status, you can quickly call.
To the second important part of the shader processing is part of this generation in the R600 core, ATI integrated up to 320 stream processing units. Of course, as with the DX10 unified architecture design, these units can handle, including vertex data, shader pixel shader, geometry processing unit and other data streams. R600 each stream processing unit contains a 5-way superscalar architecture, Shader processors, single clock cycle can handle up to 5 scalar multiply-add instructions, which go beyond the way to deal with Shader processor instructions (such as Sin, Cos, Log, Exp etc.).。 In addition, the stream processing unit can reach 32-bit floating-point precision, support integer and scalar operation, the figure of purple chunk is branch execution units, which is responsible for the flow control and conditional operations. Very interesting, from this point of view, NVIDIA and AMD in this part of the design amazing consistent, incorporates a superscalar architecture of Shader processors, AMD is still insisting on only SIMD unit design (design for non-NVIDIA SIMD).
In fact, more stream processors to use the benefits is obvious advice, it can greatly enhance the computing power, the above table compares the HD 2900XT, HD 2600XT, HD 2400XT, and a high-end CPU (two-way four-core processor) of floating point processing power, you can see, even the most low-end of the 2400XT, its theoretical floating-point computing power is able to transcend the most high-end CPU system, up 560 billion floating-point operations / second. .

AMD treatment in texture processing has always stuck to their point of view, to NVIDIA, for example, has consistently maintained its texture rendering pixel shader units and the proportion of the practice unit, or retain the current NVIDIA 2:1 ratio, such as 8800GTX, is 128 shader units and 64 texture units to pick up composition. The deal with AMD is that most of the pixels are bilinear texture filtering operation and from the integer of sampling, search process without much texture, so texture operations performance more dependent on memory capacity and bandwidth requirements on the hardware computing power not high.。.
Starting from the R580 core, ATI will be pixel processing unit and the number of texture units pulled into a 3:1 ratio, with the R600's launch, this ratio further widening trend, although the exact proportion is not good now calculated since the adoption of uniform structure, texture addressing units and pick up the same operation with Vertex Shader and Pixel Shader processing carried out separately. .
R600 built-in 4 set of texture units, each unit contains eight texture addressing processor (4x8 = 32), the implementation of the shader instruction for the texture lookup control address; each unit built 20 FP32 texture sampler (total 4x20 = 80) per clock cycle to obtain a single data value; each unit built four FP32 texture filtering units (total 4x4 = 16) per clock cycle to Bilinear filtering 1 64-bit color values, or every two clock cycles Bilinear filtering 1 128-bit color values. HD 2600 and HD 2400 texture unit has the same functionality.
Radeon HD 2000 series of multilayer texture cache design, high-capacity, shared secondary cache memory a cache miss data. Which, HD2900 with 256KB, HD2600 with 128KB, HD2400 with single vertex / texture cache. All units have access to vertex texture cache and a texture cache, for reading the unfiltered texture to provide greater throughput. .
Radeon HD 2000 series speed floating point texture filtering Full Speed Floating Point Texture Filtering with HDR texture full speed 64-bit Bilinear filtering (faster than Radeon X1000 series about 7 times), half-speed 128-bit floating point texture filtering, support all format of three linear and anisotropic filtering. Radeon X1000 series of high-quality mode, is now the default setting, problem-oriented approach of the texture. . .
In the Render Back-Ends (that is, common Rop), R600 innovations, preferred is texture compression enhancements, standard in the R600 mode can achieve maximum 16: 1 compression ratio, and previous-generation chip will only be able to reach a maximum of 8: 1 ratio of the amount of data in the game texture generally larger and larger memory will not be able to meet the needs of the game, texture compression can achieve quality lossless data reduction is, of course, the higher the better. In addition, you can separate the R600 Z cache and template data compression, thus improving efficiency.
Re-Z technology was first introduced to the R600 which it can achieve 2 Z buffer checks, one in Pixel Shader before, once after the pixel Shder. Traditional pixel shader graphics are after the Z buffer checks, such operations may now become a problem is, a pixel shader unit after the deal, take up the shader unit of Xiaoneng after, only to find Zhege pixels is required to be cut out of, shader computing has become meaningless.。.
R5xx for AMD's graphics cards, the introduction of the ring-bus (Ring bus Memory Controller) is a major feature of the memory architecture is one, R520 series, two 256bit ring bus formed by the internal bus bit width up to 512bit. With high-speed GDDR3 graphics, bandwidth 48GB / s, dual 256bit bus, and greatly reduced latency. Two-way high-speed ring memory bus structure, to R520-bit wide internal bus to a 512bit level, greatly improved on the memory access control.。.
R600 to further improve the ring-bus architecture, because the R600 in all data transmitted through the ring bus, completely through the Ring Stop data relay station exchange data, rather than a ring bus direct data exchange with the core set. Drawbacks of traditional memory architecture is that because the current data, the handling capacity of more big, more of the memory capacity and memory interface all contribute to the design complexity, the traditional design of any changes in product core, Jiu Zhong Xin design Neicun bus needs . In addition, this design is the need for more data channels, the complexity will increase the power of the number of levels.。.
Ring-bus architecture can be reached under the existing memory technology for more memory bandwidth, AMD 2nd generation ring-bus interface, external memory interface has been upgraded to a 512bit, actually refers to the card's bit width to 512bit, R600 is the memory bit The maximum width of graphics cards, memory interface for increased memory bandwidth to memory to achieve higher operating frequency of only the lower memory. But even so, R600's memory bandwidth is also an unprecedented 106GB / s, this time to upgrade than the original R5xx a lot, NVIDIA's G80 has a relatively large degree of Transcendence. .
Anti-aliasing is to enhance the quality of the game screen, this means necessary R600 and introduced a new anti-aliasing modes: 8x multi-sample anti-aliasing, and high as 24x of custom filter anti-aliasing (CFAA) mode, a new anti-aliasing algorithm can achieve programmable sampling mode, image enhancement filters, and can be driven with the upgrade. . .
CSAA with NVIDIA's (anti-aliasing covering sample) is not quite the same, CSAA has not carried out on the sampling point is too big, its colors and depth value is sampled in the pixel Center is, and will get more data through the algorithm to remove duplicate values, and color depth value, eventually use the same sub-pixel sampling point, reducing the need to save the data of the Color/Z. NVIDIA in this way is through complex algorithms to reduce data transfer bandwidth pressure form multiples enhanced anti-aliasing, but mainly rely on fewer data achieve better results, similar to increase price scenarios.
The R600 is further increased on the sample point number, and even extended to the nearby pixels to. Usually a simple rectangle graphics filter is limited to pixels within the boundary, while the R600 are joined edge detection filter, which can render images that have completed the process of edge detection, edge pixels along the edge direction using high-quality sampling filters and more processing, the other rectangular pixel sampling filters and less processed.。.
CFAA for each sample to provide better edge quality, the sampling of each pixel can be measured more than 16. CFAA to better address the contour edges (each pixel has a number of small, cross-sectional polygon), supports the template shadow are not limited to dealing with polygon edges.。.
Open 16x Adaptive CFAA, the screen effect of improved significantly, especially in points and lines, and this is that many of the mainstream anti-aliasing algorithm can not be realized. .
