Because this IBM link says Xbox 360 Tri Core is based on Power5 processors

The POWER4 series places two complete CPU cores (otherwise similar to the POWER3) on a single chip, speeds it up, and adds high-speed connections to up to three additional pairs of POWER4 CPUs. They can be placed together on a motherboard to produce an 8-CPU SMP building block. When processing requires high throughput instead of high code complexity, one of a pair of cores can be turned off so that the remaining cores have the entire bus and L3 cache to themselves. The POWER4, even in single form, is considered by many to be the most powerful CPU available.
IBM rolled out the POWER5 processor in 2004. The 1.9 GHz version posted the highest uniprocessor SPECfp score of any shipping chip. The POWER5 powers the i5 and p5 eServers. Improvements in the POWER5 over the POWER4 include: a larger L2 cache, a memory controller on the chip, simultaneous multithreading which appears to the operating system as multiple CPUs, advanced power management, dedicated single-tasking mode, Hypervisor (virtualization technology), and eFuse (hardware re-routing around faults). Ravi Arimilli, IBM's chief microprocessor designer has said: "The POWER5 chip is more of a midrange design that can drive up to the high end and then down to things like blades." IBM servers built with the POWER5 processor offer virtualization features: logical partitioning and micro partitioning. Up to ten LPARs (logical partitions) can be created for each CPU, the biggest 64-Way system can run 256 independent operating systems. Memory, CPU-Power and I/O can be dynamically moved between partitions.

EDIT: Cell processor also uses Power5:
X-Gen was developed by IBM's Haifa Research Lab. It has been a crucial element in the verification of the majority of the PowerPC-based systems in IBM, including the Cell processor, the POWER-based systems used at the heart of IBM's iSeries, pSeries, and OpenPower eServers, and the chip that drives Microsoft's XBOX 360.
