I wish I had more time to post on all of these "facts" but I am short on time today. Some of them are actual facts and other are bogus. However, fact number 6 is not a matter of opinion, it is pure 100% fact. Not only does the Xbox 360 offer developers more memory, but the memory architecture is also superior. Most games use more video memory than actual system memory. The Xbox 360 allows developers to allocate the exact amount they want without a penalty. On the PS3, you are stuck with 256MB for the Cell and 256mb for the GPU (not considering space allocated for OS)
Know what happens if the Cell wants to access the GPU memory? It has to go through the GPU which eats up a LOT of bandwidth and is slower. Want to know what happens when the GPU wants to access the super fast XDR memory? It goes through the Cell CPU and it hits the bandwidth and slows things down a LOT.
Also, one thing they didn't mention, RSX has to use memory for a framebuffer while the Xbox 360 has a dedicated 10MB eDRAM chip with 256GB/s of bandwidth which allows tiling and other advanced techniques. Thing is, developers don't really exploit it too much because it is difficult and simply not worth it. It will make the game look better, but it complicates development too much.
Sony should have gone with a unified memory architecture.
Good news Everyone!
I've invented a device which makes you read this in your head, in my voice!
