It's not surprising that someone at Microsoft thinks the Xbox 360 is going to be a much better gaming machine than the PS3. Considering Microsoft's Xbox 360 was designed to knock Sony off its roost as the #1 console gaming machine, and the PS3 is the one to beat, everyone at Microsoft should unanimously agree that their machine is tops. Engineer Matt Lee, from Microsoft's Game Technology Group, has a rather elaborate explanation as to why he thinks the cell processor is designed for something other than games. According to Matt it is the architecture of the Cell Processor that shows it wasn’t designed with gaming in mind. He observes that the Cell has a lack of branch prediction, and that since most game code contains a lot of branches, it's not likely to be the all-powerful gamer Sony would have you believe. It appears to be designed more for serialized streaming match code, which is more common in video codes and audio processing.
Matt adds that significant differences between how the PS3's Cell and Xbox 360's CPU cores will handle graphics memory mean that porting a game from the Xbox 360 to the PS3 will be particularly challenging to developers. Xbox 360 has a lot of flexible processing power that can be allocated where needed. All of Xbox 360's CPU cores have access to all memory. The Cell's architecture is designed asymmetrically, and could lead to unbalanced allocation of processing power where equal amounts are needed. Matt says that you'll never see more than 256MB of textures at any given time, due to the split graphics and system memory banks. This could lead to compromises in the quality of graphics in PS3 games. Matt boasts about Xbox 360’s 512MB of unified memory, and believes games developers and graphic artists will appreciate it.
Meanwhile, Sony is forthcoming on how the PS3's Cell Processor will benefit other consumer electronics besides the gaming machine. Sony is a market leader in almost all consumer electronics, and it seems they might plan on using the Cell Processor in other electronics devices.
Doesn't it seem that the once-bulletproof future king of consoles - the Sony PS3 - is standing on weaker ground as months progress toward its already delayed deadline?
