Yes, you sent us a cute little
summary by Microsoft. I actually checked up on the memory and stuff. I honestly have no idea how Microsoft reached the conclusion that the 360 has more processing power because they're both based on IBM's Power-PC core. It's just that the PS3 has 7 cores compared to the 360's 3. Also, you only get higher memory bandwidth if you factor in the stupid 10mb of eDRAM

The Xbox 360 GPU has more processing power than the PS3's. In addition, its innovated features contribute to overall rendering performance.
Lol - good job using a vague statement to make a "point."

Xbox 360 has 278.4 GB/s of memory system bandwidth. The PS3 has less than one-fifth of Xbox 360's (48 GB/s) of total memory system bandwidth.
Only if you count the eDRAM connection. In fact, this is, ah, somewhat
limited byt the fact that the 360 memory interface bandwidth is a whopping 22.4 GB/sec. Both the PS3's and 360's GDDR3 memory has 22.4 GB/sec bandwidth. The PS3's XDR Ram has bandwidth of 25.6 GB/sec. Yes, the connection after the GDDR3 memory interface to the eDRAM on the 360 is a whopping 256 GB/sec (because it's embedded), but the eDRAM is
only 10 MB in size and won't help out nearly as much as the GDD
R3/XDR Ram. Excluding the eDRAM (which is useless for memory intensive, i.e. all, games), the PS3 has better memory bandwidth.
Also, most of the floating point performance comes from the graphics chips. I believe the G70-based chip in the PS3 churned out nearly 1.8 Teraflops of floating point performance, which is twice that of the ATI chip in the 360. Comparatively, the Cell processor is also better than the 360 processor in terms of floating point performance, but it's still insubstantial compared to the graphics processors.
Why do you think AMD bought ATI? They're developing a new processor called "Fusion" which combines a CPU and GPU into one package. CPUs are excellent at some calculations and GPUs are excellent at others. They compliment each other fairly nicely, and when put together, you'll see something like a theoretical 1000% performance increase without even advancing the architectures of the two technologies.
Back to the subject of the PS3 vs. 360 debate. 512 mb of shared memory is nice, but often you don't want to share the memory. In cpu intensive scenes, the 360 will see a drop in fps. However, by partitioning the memory, the PS3 ensures that the GPU will always have enough memory to churn out frames. To put the final nail in the coffin, so to speak, the PS3 gpu can do 74.8 billion shader operations a second compared to the 360's 48 billion.
In conclusion, by taking Microsoft and Sony's words well salted, the PS3 is better than the 360 technology-wise, but they're both going to deliver top notch performance. Oh, by the way, the R600 can do ~103 billion shader operations a second.
*Edit* Deathawk, Vista is definitely 32- and 64-bit. It comes out in January, and I believe it can handle up to 256 terabytes of memory (the 64-bit one). Besides, I believe all Intel and AMD processors are 64-bit now, and they see serious performance gains by running in a 64-bit environment over a 32-bit environment. So yes, when I build my computer, it's going to have 4 GB of system memory in it for a 64-bit OS.
