READ PS3s VS 360s GPU ?????

KillaHalo2o9 · 2007-03-27 03:39:42

Will Im going to buy a PS3 in a week or so and, I was just wondering which system was truely the most powerfulest. We all now the GPU is the heart of the every system to display wonderfull visuals and, alot of people are saying that the PS3 cant win over the Xbox360 beause its GPU is weaker so what do you think of the tech specs? Will the Cell have enough impact to rise the PS3 higher then the 360?

[QUOTE="killab2oo5"][QUOTE="beatzfreak69"][QUOTE="GermanShepard06"]
[QUOTE="beatzfreak69"]Another thing. All of those numbers are theoretical maxes. It's also about efficiency. From what i understand the 360's GPU is like eighty something percent efficient, while the same cannot be said about the PS3's GPU.Teufelhuhn

with x360's cpu design i dont think it can even reach 30%...

Fanboyism FTL?

Xenos is able to run at 100% efficiency,thanks to the unified architecture,and thats coming from ATi.

There's no such thing as "100% efficiency". Even with all 48 shaders being used at once for vertex or pixel shading, it doesn't mean you're using all of the ALU's due to the ratio of math and texture operations in the shaders.

Your probally right,but ill take ATi's word on this one.:)
