Under the Hood of the Xbox 360
An anonymous reader writes "IBM DeveloperWorks is running a behind the design story for the making of the Xbox 360. The 360 has but a single chip with 165 million transistors for it's CPU " From the article: "This chip is in fact a three-way symmetric multiprocessor design. The three PowerPC cores are identical, except that they are physically reflected through the X and Y axis. Each of the CPU cores is a specialized PowerPC chip with a VMX128 extension related to (and partially compatible with) the VMX instructions in the G4 and G5 CPUs. The three CPU cores share a 1MB Level2 cache. Each processor has 32KB each of data and instruction Level1 cache. The chip's front-side bus/physical interface has a 21.6GB/second bandwidth, and runs at 5.4GHz."
Yes, I'd prefer this be filtered through at least a couple of blogs.
The PlayStation 3 will be made by Sony, a company which distributes software that renders a personal computer quite unstable and open to attack by malfeasant users from across the Internet.
The Xbox 360, on the other hand, is made by Microsoft.
The choice is yours.

A beowulf Heater of these... :)
One core uses little endian, one core uses big endian, and the third core exists only to map between the little and big.
