The central processing unit (CPU) consists of two x86-64 quad-core modules for a total of eight cores, [43] which are based on the Jaguar CPU architecture from AMD. [28] Each core has 32 kB L1 instruction and data caches, with one shared 2 MB L2 cache per four-core module. [44] The CPU's base clock speed is said [citation needed] to be 1.6 GHz.

The PlayStation 4, Xbox One, and Wii U all use AMD GPUs, and two of them (PS4 and XBO) also use AMD CPUs on an x86-64 architecture, similar to common personal computers (as opposed to the IBM PowerPC Architecture used in the previous generation).
For instance, earlier PlayStation 2 (PS2) systems used the core of the original PlayStation (PS1) CPU as a dual-purpose processor, either as the main CPU for PS1 mode or upclocking itself to offload I/O in PS2 mode. This coprocessor was replaced with a PowerPC-based processor in later systems to serve the same functions, emulating the PS1 CPU core.
As of 2019, no PowerPC-based game consoles are currently in production. The most recent release, Nintendo's Wii U, has since been discontinued and succeeded by the Nintendo Switch (which uses a Nvidia Tegra ARM processor). The Wii Mini, the last PowerPC-based game console to remain in production, was discontinued in 2017. [citation needed]

[225] [226] It is an upgraded version of the PlayStation 4 with improved hardware to enable 4K rendering and improved PlayStation VR performance, including an upgraded GPU with 4.2 teraflops of processing power [227] [228] [229] and hardware support for checkerboard rendering, [230] and a higher CPU clock. As with PS4 "Slim", this model also ...
The CPU core is a two-way superscalar in-order RISC processor. [3] Based on the MIPS R5900, it implements the MIPS-III instruction set architecture (ISA) and much of MIPS-IV, in addition to a custom instruction set developed by Sony which operated on 128-bit wide groups of either 32-bit, 16-bit, or 8-bit integers in single instruction, multiple data (SIMD) fashion (e.g. four 32-bit integers ...
