It's already been shown, though many tests, that 1 SPU can equal or surpass Intel's top single core processor in many tasks. The inter-core bandwidth has been proven at 197GB/s. The link from my percious post shows Intel Core i7 965XE's TOTAL bandwidth (cache, memory, and inter-core bandwidth) is 106GB/s. Plus, it only has 4 cores at 2 ops per clock. Also, I can't believe you talked about running code/apps not written for it's architecture! That's a bit like saying 2.4GHz PowerPPC processor would demolish an Intel Core i7 965XE at Linux written specifically for PPCs. LOL. It's just that the code is written to take advantage of different architectures.

I would like to see those tests. If you get me ps3, I can also make program for it which runs fine on Xbox(original) and really doesn't run well on ps3 even if you find any expert to optimate that program in anyway but still making it function like original(Of course).

 

Btw, parallizing is very easy on homogeneous platform.

Against the fastest single cores (like Intel Xeon)...1 SPE can perform up to 7 times better than a single core 3.6GHz Intel Xeon.

Performance comparison between Intel/AMD dual-core processors versus Cell...also partially explains that realism iin games is not limited by the GPU anymore.

Cell beats Intel Quad-Core (Clovertown) at DP GFLOPS, which it's terrible at compared to it's SP (just divide the chart number in half for Cell due to Cell blade being used).

The last 3 links were to GameTomorrow.  That site is down, but a search will reveal that information on other site.

 

You posted old links or links to IBM. Of course, IBM will claim that their product is better.

OT: The truth is that the PS3 is more powerful than the 360 the same way the Xbox was superior to the Gamecube. Anyway, Microsoft doesn't even try to make really graphically impressive games. You just have to look at how better Halo and Gears of War sold than Uncharted and Killzone 2.
