What is 1/ and 1/ from the powerful modern graphic processor, or ATI RADEON HD 2400XT/2600PRO/2600XT (RV610/630) Though architecture AMD R6xx has been announced in May, on the market the decision of the top price range on the basis of chip R6 has at that time acted only, and other videocards and chips on the basis of unified architecture R6xx have been postponed for some time, about them only theoretical data were known. Sadly to observe, how somewhere after 20 company ATI has gradually started to give in in competitive struggle with NVIDIA. After fading 3dfx in 2000-2001, there has come time of domination of company NVIDIA which has been broken by nick cassavetes notebook bright approach of videochips of ruler R3xx and corresponding videocards RADEON 9x from company ATI and a number of mistakes most NVIDIA (to recollect unsuccessful ruler GeForce FX enough). Since then and somewhere till 20 we with pleasure observed of interesting struggle of two strong competitors from which to users there was only a benefit they received worthy products from two companies and in time. And here then at ATI there has come time of stagnation, since then and till now they strongly enough are late with an output of the products for the market. That was with decisions on the basis of a ruler of chips R5xx, the same has turned out and with R6xx. This all inevitably affects sales, on a market share of the company and on its financial well-being. But here the moment of an output on the market low-end and mid-end nick cassavetes notebook decisions with support DirectX from AMD, at last, has come, from the moment of their initial announcement has passed not enough time. The basic difference of chips RV6 and RV6 from topovogo R6 is the "know-how" of nanometers which allows to lower the cost price, rather important for inexpensive products and which, possibly, just and has affected terms of a conclusion of corresponding decisions on the market. Now business behind receipt of necessary volumes of new videocards in shops. Before perusal of a material we traditionally recommend to familiarize closely as with all previous clauses under decisions on the basis of the unified architecture, and with base theoretical materials DX Current, DX Next and Longhorn, describing various aspects of modern hardware accelerators schedules and architectural features of production NVIDIA and ATI (AMD). These materials have precisely enough nick cassavetes notebook predicted a current situation with architecture of videochips, many assumptions of the future decisions were justified. DX.Next: the nearest and near future of hardware acceleration 3D-grafiki Graphic accelerators RADEON HD 26 PRO and HD 26 XT The unified architecture with a file of the general processors for potokovoy processings of tops and pixels, and also other kinds of data Hardware support DirectX 10, including new sheydernoy models Shader Model 4.0, generation of geometry and record of intermediate data from sheyderov (stream output) 1 scalar ALU with a floating point (integer and floating formats, support FP of accuracy within the limits of standard IEEE 754) textural blocks, support FP and FP a component in structures blocks of textural addressing (see details in base clause) blocks of textural sample (see details in base clause) blocks of a bilinear filtration with an opportunity of filtration FP of structures on full speed nick cassavetes notebook and support trilineynoy and an anisotropic filtration for all textural formats blocks ROP with support of modes antialiasinga with an opportunity of programmed sample more than samples on pixel, including at FP or FP a format of the buffer of the staff. Peak productivity up to readout for a step, in a mode without color (Z only) readout for a step The integrated support of two RAMDAC, two ports Dual Link DVI, HDMI, HDTV Effective frequency of memory of 14 MHz (2*7 MHz)/22 MHz (2*11 MHz) Two DVI-I Dual Link a socket, the conclusion in sanctions up to 2560h16 is supported Two DVI-I Dual Link a socket, the conclusion in sanctions up to 2560h16 is supported Graphic accelerators RADEON HD 24 PRO and HD 24 XT The unified architecture with a file of the general processors for potokovoy processings of tops and pixels, and also other kinds of nick cassavetes notebook data Hardware support DirectX 10, including new sheydernoy models Shader Model 4.0, generation of geometry and record of intermediate data from sheyderov (stream output) scalar ALU with a floating point (integer and floating formats, support FP of accuracy within the limits of standard IEEE 754) textural block, support FP and FP a component in structures blocks of textural addressing (see details in base clause) blocks of textural sample (see details in base clause) blocks of a bilinear filtration with an opportunity of filtration FP of structures on full speed and support trilineynoy and an anisotropic filtration for all textural formats blocks ROP with support of modes nick cassavetes notebook antialiasinga with an opportunity of programmed sample more than samples on pixel, including at FP or FP a format of the buffer of the staff. Peak productivity up to readout for a step, in a mode without color (Z only) readout for a step The integrated support of two RAMDAC, two ports Dual Link DVI, HDMI, HDTV One DVI-I Dual Link the socket, is supported a conclusion in sanctions up to 2560h1600 One DVI-I Dual Link the socket, is supported a conclusion in sanctions up to 2560h1600 Some of features of all decisions of a ruler: the unified superscalar architecture, programmed hardware tesselyator, the improved support of decoding of video Avivo HD, native support CrossFire. Architecture of new chips unified, nick cassavetes notebook all of them possess high-grade support DirectX and even more than some opportunities which will appear in following versions of it API. Already after the announcement topovogo decisions R6 one interesting detail became known has appeared, what not all new decisions of company AMD are functionally identical by way of hardware support of decoding of videodata as it has been declared at the announcement initially. Precisely as well as at NVIDIA, low-end and mid-end chips of ruler AMD would possess about l'shimi opportunities on decoding video as in chip R6 whether in general there is no that improved block on processing video (UVD), nick cassavetes notebook whether it is, but works with mistakes... In any case, research of productivity and quality of decoding of video new decisions of the company is beyond this material, but we shall necessarily consider opportunities of new chips, having added their results in last research on a theme. So, AMD the first enters into a market graphic decisions of average and bottom levels which chips are executed on nanometers to technological norms. As we more than once spoke, such transitions are important, as more perfect technological processes give advantage, allowing to achieve the smaller size of a kernel or a lot of transistors at the same area, increasing frequency potential of chips nick cassavetes notebook and percent of an output suitable on high clock frequencies, and also reducing the cost price of manufacture. One more major advantage is lowered e`nergopotreblenie, new mid-end and low-end chips AMD consume much less energy and allocate less than heat, in comparison with competing. In the last clause, architecture R6xx devoted to the announcement and output RADEON HD 29 XT, we have in detail told about all architectural features of new ruler DirectX of videochips of company AMD, in this material there will be only their brief description, for other data address under the reference specified above. Architecture R6xx combines some decisions from previous: R5xx and Xenos (the videochip of console Microsoft Xbox 360), supplementing nick cassavetes notebook with their various innovations: more powerful dispatcher of streams, sheyderny'h processors with the allocated blocks of branching, etc. the New architecture is well scaled by superscalar architecture in both parties, that we and see on an example low-end and mid-end decisions. Schemes of chips RV6 and RV6 look so: It is well visible, that RV6 differs from R6 only quantity of various blocks: ALU, ROP, TMU, in all rest repeating the senior brother. At RV6 it is more than differences, they not only quantitative (blocks ALU and TMU became even less), but also qualitative: is not present hierarchical Z-bufera, there is no second level of a textural cache, and the unique level combines ke`shirovanie topmost and nick cassavetes notebook piksel'ny'h data. The basic quantitative changes: the number sheyderny'h processors in RV6 is lowered up to (1 processors) and in RV6 up to ( processors), number of blocks teksturirovaniya up to and 4, accordingly, and blocks ROP at younger chips on four. Naturally, all it is made to please to smaller number of transistors and will negatively affect productivity rather topovogo decisions of a ruler. About all other architectural details of decisions R6xx you can learn from a base material, the reference on which is resulted above. Naturally, younger chips do not have support 512-bitnoy the trunk, but all other, written in that material, concerns nick cassavetes notebook and to them completely. Even moreover, written about Avivo HD concerns just to them, instead of to topovomu to the decision. Further we will have a practical part of research in which we learn how productivity of new inexpensive decisions on the basis of videochips RV6 and RV6 corresponds with speed of competing videocards NVIDIA, and also shall check up, their reduction is how much strong has affected at speed rather topovogo the chip of family R600.
