Xbox 360 Video card

I was looking over the specs of the new xbox 360 and i noticed it had SIXTY FOUR pipelines. My only thoughts were HOLY S($# this thing is insane, im sure this probaly isn't the final specs on it, but if it is shouldnt it BLOW the 7800GTX and the PS3 video card away? This is going to be one hell of a card if theres really 64 pipelines on it.

dont know where you got the 64 pipeline figure. but here are the specs for the xbox 360

as well as here:

http://www.extremetech.com/article2/...1818127,00.asp

All 48 of the ALUs are able to perform operations on either pixel or vertex data. All 48 have to be doing the same thing during the same clock cycle (pixel or vertex operations), but this can alternate from clock to clock. One cycle, all 48 ALUs can be crunching vertex data, the next, they can all be doing pixel ops, but they cannot be split in the same clock cycle.

and here:

So 48 Unified shaders, not 64 pipelines. The unified shaders means that it shares between pipes and vertex shaders....whereas the 7800gtx has 24 dedicated pipes and 8 dedicated vertex shaders:

Specs for the 7800gtx:
• 430MHz core clock speed
• 1.2GHz 256MB GDDR3 memory
• 256-bit memory interface
• 38.4GB/s memory bandwidth
• 24 pixels per clock
• 10.32Bps Fill Rate
• 8 Vertex Pipes
• 860M vertices/second
• 400MHz RAMDACs
• NVIDIA CineFX 4.0 engine
• Intellisample 4.0 technology
• 64-bit FP texture filtering & blending
• NVIDIA SLI Ready
• DX 9.0 / SM 3.0 & OpenGL 2.0 supported


plus, the 7800gtx has higher clock speeds, which give it more memory bandwidth, but lower fillrate. So I would say they are about equal performance wise based on specs.

Wow thanks, not sure which site i got the 64 pipelines from, but thanks for clearin that up for me.
