G80 and R600 have different architecture

This website explains to you the difference between the shader power in G80 and R600

Both AMD and Nvidia like to throw around peak FLOPS numbers when talking about their chips. Mercifully, they both seem to have agreed to count programmable operations from the shader core, bracketing out fixed-function units for graphics-only operations. Nvidia has cited a peak FLOPS capacity for the GeForce 8800 GTX of 518.4 GFLOPS. The G80 can co-issue one MAD and one MUL instruction per clock to each of its 128 scalar SPs. That's three operations (multiply-add and multiply) per cycle at 1.35GHz, or 518.4 GFLOPS. However, the guys at B3D have shown that that extra MUL is not always available, which makes counting it questionable. If you simply count the MAD, you get a peak of 345.6 GFLOPS for G80.

By comparison, the R600's 320 stream processors running at 742MHz give it a peak capacity of 475 GFLOPS. Mike Houston, the GPGPU guru from Stanford, told us he had achieved an observed compute throughput of 470 GFLOPS on R600 with "just a giant MAD kernel." So R600 seems capable of hitting something very near its peak throughput in the right situation. What happens in graphics and games, of course, may vary quite a bit from that.



As you see, 8800GTX have either 518.4 GFLOPS or 345.6 GFLOPS (depending on how you count them)

well hopefully this will lower the 8 series significantly

The Qx6800 is pretty hard to find. You can find one either OEM or in a pre-built system.

the qx6800 is out already?? i never knew that...
Yea, QX6800 came out on April 2007

However, Penryn is supposed to come out on Q4 2007, at same time when G92 comes out.

Penryn + G92 = Ultimate gaming machine.

And for people who want a true DX10 video card, they need to wait for G92 because it seems that both G80 and R600 can't handle DX10 games on highest settings.

Why not!? Beating dead horses is great for customers!

No it's not, it's the exact opposite. We need AMD to keep releasing cards that are competitive so everyone wins and Nvidia can't just price things how they please.

well lets see how the r700 and r650 (which i might get...) do.

We will see...I hope they are good and not a let down like the R600.
