Template:mpu Scorpio Engine is a 64-bit octa-core x86 SoC designed by AMD and Microsoft for their Xbox One X. The chip features eight Enhanced Jaguar cores operating at 2.3 GHz and a custom Arctic Islands-based GPU operating at 1.172 GHz. Fabricated on TSMC's 16FF+, this chip supports 12 (24 for Dev) GiB of 12-channel GDDR5-6800 memory.

Cache Organization
Cache is a hardware component containing a relatively small and extremely fast memory designed to speed up the performance of a CPU by preparing ahead of time the data it needs to read from a relatively slower medium such as main memory.

The organization and amount of cache can have a large impact on the performance, power consumption, die size, and consequently cost of the IC.

Cache is specified by its size, number of sets, associativity, block size, sub-block size, and fetch and write-back policies.

Note: All units are in kibibytes and mebibytes.
