Xbox One SoC rivals AMD’s Tahiti for size, complexity

We've known the outlines of the Xbox One's AMD-designed SoC for a while now, including its eight Jaguar CPU cores and GCN-class integrated graphics. One of the primary revelations to come out of Hot Chips is the SoC's sheer size: the thing is 363 mm² and is comprised of roughly 5 billion transistors; it's produced at TSMC on a 28-nm HPM process.

To give you a sense of scope, the Tahiti GPU that powers the Radeon HD 7970 is also produced on a 28-nm process at TSMC, and Tahiti packs 4.3 billion transistors into 365 mm²—so the two chips are quite comparable in size.
