Could someone explain PS3/Xbox360 Teraflops?

*why was the original thread deleted? i received no warning, no pm, no explanation, and no one replied. so can someone either confirm or deny this? ty*

Got this from neowin but couldn't find the thread that calculated this.

--------------------------
Here are the facts: Nvidia uses separate Vertex and Pixel Shaders, ATI uses a Unified Shader which does both Vertex and Pixel Shading using the same Shader. When Nvidia calculates performance, it totals both Vertex and Pixel Shaders running at peak efficiency. When ATI calculates performance, it totals the performance of the single unified shader (composed of both Pixel and Vertex shaders) at peak efficiency. So this means that in order to compare ATI's performance to Nvidia's, you would double the rated performance.

PS3:

CPU=0.25 TFlops

GPU=1.80 TFlops for both Pixel and Vertex Shaders

XBOX360:

CPU=0.18 TFlops

GPU=0.88 TFlops for Unified Shaders=1.75 TFlops for combined Pixel and Vertex Shaders

So the PS3 has a total theoretical of about 2 TFlops and XBox 360 has about 1.9 TFlops (counting Pixel and Vertex shaders separately, as thr PS3 does).

It was locked because the numbers are wrong and because this is being debated to death on 92 other threads.

k, thanks could you point me in the right direction?
