heh I am not as knowledgable as you are so I dont understand as much
But I d like to see direct comparissons and explanations between the two when complete information is available for both.
My estimation though is that if Sony are indeed honest with their tech demos especially like the Killzone Demo being achievable in real time (the guy from Epic said that the tech demos are all achievable) then I expect similar GPU performance with the Cell boosting up performance.
If the killzone was accurately done to spec then something must be freeing the general performance from taking a hit.
The smoke, explosion effects, complicated physics, draw distance, moving objects, possible complex AI etc all these being processed constantly at the same time and flawlessly need huge processing power.thats why I am not sure if its achievable.
But lets assume that it is.
From what I ve heard that one of the Cell\'s main purposes is to free the GPU from doing more complicated tasks that could lead to performance hit.But the Cell I believe was designed so it wouldnt sacrifice from its power trying to "assist" either.
Its ability to handle multible tasks like a network of CPUs may mean that it can do them without sacrificing anything or atleast much.
Time will tell though
