nVidia G80 vs. ATI (AMD) R600

[chaminga_d]

Nope. Sure ATI is a bit late, but architecture wise R600 and G80 are comparable. G81 will be just a small improvement over G80 (like GF7800 vs GF7900).

small improvement?????? all are improved...
* 65nm
* 64 Shader pipelines (Vec4+Scalar)
* 32 TMU's
* 32 ROPs
* 128 Shader Operations per Cycle
* 800MHz Core
* 102.4 billion shader ops/sec
* 512GFLOPs for the shaders
* 2 Billion triangles/sec
* 25.6 Gpixels/Gtexels/sec
* 256-bit 512MB 1.8GHz GDDR4 Memory
* 57.6 GB/sec Bandwidth (at 1.8GHz)
* WGF2.0 Unified Shader

65nm = better power consumption and cooler operation

I can only see two differences: Core clock speed has improved, and they have moved to GDDR4 (still doesn't make it faster because the clock speed is the same - but will lower the power consumption)

Pretty much similar to AthlonX2 90nm 4800+ and 65nm 5400+. Not like AthlonX2 4800+ and Core2Duo 6600.

Sorry It's my mistake....

Oh ok. No problem dude.

Still too early to drop into conclusions, but we'll see in a few months' time.
