Here is a side-by-side
Comparison of GPU specs
Clockspeed in MegaHertz: 550 (PS3), 500 (360)
GigaFlops (Billions of Floating Point Operations Per Second): 1,800 (PS3), 240 (360)
Billions of Dot Products per Second: 1,800 (PS3), 240 (360)
Millions of Polygons per Second: 900, 1,800 with CPU handling culling (PS3), 500 (360)
Shader operations per clock cycle: 136 (PS3), 96 (360)
Billions of Shader operations per second: 74.8, 100 with CPU (PS3), 48 (360)
Texture lookups per clock cycle: 24 (PS3), 16 (360)
Texture lookups per second: 13,200 (PS3), 8,000 (360)
Vertex/Pixel Shader pathways: 24 pixel, 8 vertex (PS3), 48 shared (360)
Shader ops per pathway: 5.7 (PS3), 2 (360)
Video RAM
Amount in Megabytes: 256 Dedicated, 256 Shared (PS3), 10 Dedicated, 512 Shared (360)
Clockspeed in MegaHertz: 700 Dedicated, 3,200 Shared (PS3) Unknown Dedicated, 3,200 Shared (360)
So as you can see, 360’s GPU is not superior to RSX in any single way. Using official specs.
As for Bluray vs DVD
Disc Transfer rate in Megabytes per Second
-Single Layered discs
PS3: 9 (average: 9)
360: 6.65 to 16 (average: 13.3)
-Dual Layered discs
PS3: 9 (average: 9)
360: 4.389 to 10.64 (average: 7.5145)
When it comes to real world, the 360 has had the upper hand for a while now, and as PS3 titles are comming out, the PS3 is looking better and better as programmers get the hand of the code. The PS3 will continue to look better as games take advantage of its full potential.
