Not really. The CPU is more advanced than the 360, but the RAM is gimped by being split in half ( the main reason PS3 hasn't gotten the previous DLC yet according to Bethesda ).The PS3 is the more powerful of the two, but it's not by a large margin.
Graphically the PS3 is a good bit ahead, but you have to do work with shading on the SPUs and so forth to gain the advantage.The PS3 can allow more system ram to be used for graphics, just not the other way around.
Everyone talks about how the Xbox is so like the PC, but what PC have you ever seen with an odd number of cores and a unified memory pool? None, zero nada zippo..
Lower end computers with integrated graphics chipsets (intel, via etc) allocate system ram for graphics operations but pagetable protections are used to keep those areas segregated.
The biggest bottleneck for PS3 programming is the size of the DMA regions for each SPE. As I understand it the SPEs can only operate on data within their DMA region, so all data must be shuffled into the SPE DMA, if you create objects that are basically too big then a lot of cycles are wasted in off-copying bits in and out of the DMA pools.
I think in terms of pure computational throughput and speed the PS3 is quite a bit ahead of the Xbox.But its irrelevant I think because the BS team is clearly not devoting much time to OpenGL programming.
So if there is absolutely PS3-specific it might be something with the six-axis controller or maybe the OS provided screenshot function? But I agree with most, the PS3 is just going to _finally_ get some of the content everybody else has had for a while.
