erm not an atom that's wrong in so many levels. that's for sure, maybe gpu will be better but even a core 7i barely gets to floating point performance of cell based cpus. and windows games have a performance hit of using directx and a slow system OS running on the back. |
I'm talking real-world performance, not theoretical performance. The PS3 and XBox 360 have demonstrated in game performance that puts them in line with the Athlon 64 X2 and low end Core 2 Duos, which the Intel Atom D525 is in the same (basic) range. Both the PS3 and XBox 360 have (potentially) more powerful CPUs than the Intel Atom, but probably not to the extent that some would believe; and anyone who believes that the Cell can compare to an i7 in real world performance has been drinking the Sony Kool-Aid.
edit: Just to make my point clearer ... Back in the mid/late 1990s there were DSPs that were able to decode an MP3 in less time than it took an Intel Pentium II processor to do the same process; and these DSPs sold for 5% the cost of the Pentium II processor. This (of course) did not make these processors faster than the Pentium II, they just made them better suited to the task of decoding an MP3.
The Cell processor is really well suited to certain tasks (in particular in scientific computing) but very rarely will a task line-up in such a way where the theoretical processing power of the Cell can be realized. As we’re approaching the 6 year mark of developers working with the Cell processor, and it still showing very little benefit over processors with a fraction of its theoretical processing power, it should be obvious that the Cell processor is a poor fit for most modern videogames.
