Hot off the presses:

Jaguar is AMD’s first 28nm processor, a compact 3.1mm2 design that targets 2-25W devices. It is a derivative of the earlier 40nm Bobcat, a fully out-of-order two issue design, with significant improvements in instruction set architecture and implementation. Some of the highlights include support for AVX, wider 128-bit datapaths, and a higher performance L2 cache. Jaguar is already shipping in several AMD SoCs targeted at tablets, notebooks, microservers, and desktops. However, it is far more prominent as the CPU powering the Sony Playstation 4 and Microsoft Xbox One.

The full Jaguar article is probably my last 'big' microarchitectural piece for a while.

I want to give a huge thanks to a number of anonymous RWT readers who contributed to this article. As always, feedback, comments and questions are welcome.

And if you happen to be in the Austin area next weekend, you can quiz me over BBQ.
