Even though ATI has not yet confirmed the specs of its R520/Fudo and has been successful in silencing everyone in the know with a variety of legally binding documents, the R600 specs appear to have been leaked.
It's a funny business this graphics war; it appears that staying in the headlines is extremely important when your rival releases their product and ATI is trying to steal as much thunder as it can without sacrificing its, apparently very hush-hush, R520 specs. What better way to face-up to your enemies specs than mentioning yours for a product that is over one year away.
According to recent news, originating in Canada, spread on a few hardware forums the new ATI R600 chip will be released around November/December 2006. The full specs include a stunning 64 shader pipelines, GDDR4 memory and will be built on 65 nm. The full specs leaked are as follows:
64 Shader pipelines (Vec4+Scalar)
128 Shader Operations per Cycle
102.4 billion shader ops/sec
512GFLOPs for the shaders
2 Billion triangles/sec
256-bit 512MB 1.8GHz GDDR4 Memory
57.6 GB/sec Bandwidth (at 1.8GHz)
WGF2.0 Unified Shader
Considering that boards based on this chip are over a year away and that graphics manufacturers change their mind about specs almost daily, these should really be treated as guidelines, or better still, as a what if... news story
