AMD's ATI Radeon HD 2600 features 120 stream processors

AMD’s next-generation graphics products are right around the corner. The next generation ATI Radeon HD 2000-series includes a top to bottom DirectX 10 lineup consisting of the HD2900, HD2600 and HD2400-series. Although DailyTech unveiled benchmarks of AMD’s upcoming ATI Radeon HD 2900 XT last week, details of the mainstream and value HD 2600 and HD2400-series have remained scarce.

AMD’s next-generation ATI Radeon HD 2600, based on the RV630 core, features 120 stream processing units with three SIMDs and two texture units. There will be two ATI Radeon HD 2600 GPUs: a Pro and XT model with different clock speeds and memory requirements.

AMD and add-in board partners will offer a variety of ATI Radeon HD 2600-based graphics cards. The different models include variations with GDDR4, GDDR3 and DDR2 memory in 512MB or 256MB configurations with or without video input and output capabilities.

Catering towards value users is the ATI Radeon HD 2400 with its 40 stream processors. Two SIMDs and one texture unit join the 40 stream processors. AMD plans to offer the ATI Radeon HD 2400 in Pro and LE models with varying configurations. ATI Radeon HD 2400-based graphics cards will have 256MB or 128MB of video memory. Add-in board manufacturers are free to set the output configuration, including VGA, dual-link DVI, video input/output, HDMI and DMS-59 outputs on ATI Radeon HD 2400-based graphics cards.

One Texture Unit

Will one texture unit be enough, for ATI's new mainstream parts, considering my X1950Pro has 12 texture units, 12 pixel piplines, 36 pixel shaders and 8 vertex shaders? Will the 2 SIMD units perform a greater function for the future of ATI video cards, maybe replacing the need for higher number vertex shaders?

The value line has one texture unit. The mainstream cards have two. At any rate, I dont think you can simply compare the numbers here.

One texture "unit" means a cluster of 4 units.

Article doesn't mention ROPs counts. Both HD 2400 and HD 2600 have 4 ROPs (one cluster).
