There's a good chance you've heard a lot about the insides of the Xbox One, but there's much that's still unclear regarding the CPU, eSRAM and its API. Microsoft have combined forces with AMD (who're responsible for creating much of the chips residing inside the machine) to hold an event which explains much of the jiggery-pokery inside Microsoft's flagship console.
The Xbox One, as you're likely familiar with by now uses AMD's Jaguar CPU (the same type which power Sony's machine), these are arranged in two clusters of four cores (eight total), and are running at 1.75GHZ. They are Dual Issue (meaning that for each clock cycle the processor can move two instructions from one stage of the pipeline to another) and supports both Out-of-Order and Speculative Execution. The Jaguar also supports SSE4.2 and AVX too -- just for good measure. For Cache, the jaguar has 4 MiB of L2 (that's 2 MiB per cluster), and is 16-way associative, allowing each cache requests to be in flight simultaneously (per core).
