Sam mialem to wrzucic na forum XBox'a.
Prawda jest taka:First of all the PS3 blows the 360 out its ass on specs , and those comparisons weren't even Professionally done , And you could easy tell , Forst of all the 360 is running at 3.2GHz with 3 cores , 3 cores!! meaning that it is really running at about 1.0GHZ in 3 ways , Just adding up to 3.2GHZ , thats cool , but not that cool! compared to the CELL , The CELL is running at 3.2GHZ 7/SPE , Do any of you even understand what that means!? That means the processor alone is running at 3.2 GHZ alone , ALONE!!!! , each SPE is running with it's own CPU and RAM , pretty much putting the power of 8 High tech PC's into one , Now tell me how the 360 does that , and you will be sorry , and stupid , because the 360 cant do that idiots!!! Second of all , If you all want to compare the PS3 and 360 by graphics , I think you all need to read a lil more carefully at what the Processor is also capable of , because the CELL also helps in the situation . The main differences between an individual SPE and an early RISC machine are twofold. First, and most obvious, is the fact that the Cell SPE is geared for single-precision SIMD computation. Most of its arithmetic instructions operate on 128-bit vectors of four 32-bit elements. So the execution core is packed with vector ALUs, instead of the traditional fixed-point ALUs. The second difference, and this is perhaps the most important, is that the L1 cache has been replaced by 256K of locally addressable memory. The SPE's ISA, which is not VMX/Altivec-derivative (more on this below), includes instructions for using the DMA controller to move data between main memory and local storage. The end result is that each SPE is like a very small vector computer, with its own "CPU" and RAM. This RAM functions in the role of the L1 cache, but the fact that it is under the explicit control of the programmer means that it can be simpler than an L1 cache. The burden of managing the cache has been moved into software, with the result that the cache design has been greatly simplified. There is no tag RAM to search on each access, no prefetch, and none of the other overhead that accompanies a normal L1 cache. The SPEs also move the burden of branch prediction and code scheduling into software, much like a VLIW design.
The SPE's very simple front end can take in two instructions at a time, check to see if they can operate in parallel, and then issue them either in parallel or in program order. These two instructions then travel down one of two pipes, "even" or "odd," to be executed. After execution, they're put back in sequence (if necessary) by the very simple commit unit and their results are written back to local memory. The individual SPUs can throw a lot overboard, because they rely on a regular, general-purpose POWERPC processor core to do all the normal kinds of computation that it takes to run regular code. The Cell system features eight of these SPUs all hanging off a central bus, with one 64-bit POWERPC core handling all of the regular computational chores. Thus all of the Cell 's "smarts" can reside either on the PPC core, while the SPUs just do the work that's assigned to them.
Note also that the register file has six read ports and two write ports. The SPEs can do forwarding and bypass the register file when necessary. The SPE has a DMA engine that handles moving data between main memory and the register file. This engine is under the control of the programmer as mentioned above. Each SPE is made of 21 million transistors: 14 million SRAM and 7 million logic. Finally, the instruction set for the SPEs is not VMX compatible or derivative, because its execution hardware doesn't support the range of instructions and instruction types that VMX/Altivec does. Now if any of you wanna keep battling with this , go ahead , because all the info is right here from a Professional on just the Processor , and guess what , The CELL is the most high tech Processor to date , and Sony and IBM pretty much made it , so nobody besides Sony can geta hold of it , therefore , Microsoft can even try to change there processor , PS3 will be much better in terms of specs , because almost everything is done ten fold , Thank you.
Informacje sa z bloga majora nelsona (super gosc, mowil ze chca sprzedac bilion X360), IGN powiedzialo ze nie poprawialo informacji tylko je wkleilo z emaila (profesjonalizm). Widac ze M$ sie tylek pali po tym jak zobaczyli mozliwosci PS3.
Aha Cell jest jednostka zbudowana przez SONY, IBM i TOSHIBE co sprawia ze M$ nie moze polozyc na nim swoich lap.
