“At this year’s E3 (or thereabouts) Sony proclaimed that their processor could achieve 200GFLOPS! However, according to IBM’s white paper, only 155.5 GFLOPS was actually achieved (Table 4). BUT, IBM’s tests used all 8 SPEs. The PS3 will only use 7 SPE’s, due to manufacturing yield issues.What? 133.6GFLOPS? 133.6GFLOPS doesn’t look very much like 200GFLOPS. The Xbox360 is capable of 115GFLOPS. I may not be too great at Math, but that seems a little far from the “twice the processing power of the Xbox 360″ statement that was thrown around by Sony execs in the past. I will never understand why the army of Sony fans will defend a brand who lies to them time and time again whenever new hardware is released.
The efficiency of the Cell is 75.9% (Table 4), with of a theoretical peak of 201GFLOPs (Figure 5)–running 8 SPEs at 25.12GFLOPS apiece (Table 2). Similarly, the theoretical peak for the PS3’s processor will be 176GFLOPS, using 7 SPEs at 25.12GFLOPS apiece. Assuming the same 75.9% efficiency, we could easily interpolate the PS3’s Cell to be capable of 133.6GFLOPS.”
With this news, and word that the OS on the PS3 might be sucking down 19% of the processing power, Microsoft is making the Xbox360 look more and more honest and consumer friendly. Not in the way that it’s easy to use, but the fact that Microsoft doesn’t seem to lie to the consumer about the Xbox360.
This was also in their report:
“…Not to mention that one of the SPE’s in the PS3 are reserved for the OS and the bottlenecking of the data transfer between the SPE’s and the on board memory. I see the 360 hand in hand with a gaming Revolution taking home this next round at least, if not the whole cake over time.”Things are looking up for the Xbox 360’s position in the consolewars.
