AMD announced the new generation of 3D graphics ATI Radeon HD 2000, formerly known under the working title R600, and announced the start of sales of new products in five series. To say that the announcement was delayed decently - virtually nothing to say but, taking into account the fact that the influx of charge, any DirectX 10 applications in the market "does not smells" still, in principle, in the long refine Radeon HD 2000 can be rezon find.

Today, we offer the results of the first detailed studies of productivity maps Radeon HD 2000, but before it does not do without theoretical assumptions about the architecture of the new Radeon graphics processor. Change is indeed radical, in fact, to some extent it makes sense to talk not so much about the changes, but about innovation, for the first time in its new chips. Those who are extremely interested in the facts - specific figures obtained from the tests and comparative test may traditionally open the last page article, but readers interested in why such results was reached, still advised to take a few minutes to study the characteristics of the new chips.

Unlike typical announcements of past years, AMD announced at the same time the whole new line of graphics cards in all price segments - from budget to high-end. The base of the new series are three:

Of course, primarily interested in all characteristics "masthead, the most productive graphics cards that have received the title of AMD ATI Radeon HD XT 2900, which chips are made on production lines subject to the rules 80 nm technological process. However, rulers ATI Radeon 2400 (working title RV610 chip), and ATI Radeon 2600 (working title RV630 chip) no less curious because, following a well established tradition, are on the lines with more Precision - 65 nm technological process. The complete list of the five new series looks like this:
Despite the different levels of productivity and other technical differences, the series brings together all the key feature - Support for DirectX 10. At the same time, declared a number of new key technologies: unified shader architecture Unified Shader Architecture (what is interesting acronym!) With up to 320 "streaming processors, and support Shader Model 4.0, the function tesselyatsii (Tessellation), support for memory GDDR2/GDDR3 (and GDDR4 at HD 2600), HDMI / HDCP, the new incarnation Avivo functions performed Avivo HD and a lot of other things, more than a little further.

Video series Radeon HD Pro 2400 and 2400 Radeon HD XT positioned as the most affordable solutions with support for DirectX 10, ATI Avivo HD technology. Maps are built audiochipom that allows full use of opportunities HDMI connector at no additional connections. RV610 kernel containing 180 million transistors, contains 40 processors with streaming unified Shader architecture, a key difference between the Pro and XT versions is the nucleus of bar frequencies - 525 MHz and 700 MHz respectively. A typical version of the support for such memory cards - 128 MB, or 256 MB 64 - bit GDDR2, while also expected variations from 256 Mb GDDR3. Bar-frequency versions of the Pro position will be at 400 MHz, the XT - at 800 MHz, and the lower threshold price will be even lower than $ 99.

With regard to graphics cards series RV630 chips - Radeon HD 2600 Pro and Radeon HD XT 2600, in addition to the standard for all new products support DirectX 10, the technology they support Avivo HD with HD video processing hardware, have 5.1-channel audio output to HDMI, working in the configuration CrossFire. Chips Radeon HD 2600 contain approximately 390 million transistors, 120 streaming processors. Bar-frequency chips Radeon HD 2600 Pro - 600 MHz chips Radeon HD XT 2600 - 800 MHz. Shiny new memory card 128 - bit, we can expect a wide range of options, with 256 Mb DDR2 memory, GDDR3 or GDDR4. Memory start bar frequency from 400 MHz versions for Pro, and up to 1100 MHz for the XT models. Prices card Radeon HD 2600 Pro promised in the range , Radeon HD cards 2600 XT - in the range. The most interesting - it is, of course, the High-end cards ATI Radeon HD XT 2900 issued "to fight" with its direct competitor - maps NVIDIA GeForce 8800 GTX. Chips Radeon HD 2900 XT implemented on the base of about 700 million processors have streamed 320 processors, support the 64 - bit HDR mode (128 - bit processing with a floating point texture), improved treatment HQ anisotropic filtering and texture to 8192x8192 HR. This is complemented by 512 - bit memory interface - eight 64 - bit channels. Supported CrossFire mode, there is a built-HDMI output with its own integrated 5.1-channel sound. The version with 512 MB 512 - bit DDR3 memory, ATI Radeon HD cards 2900 XT originally promised for sale interesting price - around $ 399, and this is not a joke, because in some European runoff such cards.
