Additional RAM is integrated with the GPU (including a 1 MB framebuffer) and SPU (512 KB), see below for details. Cache RAM for CPU core and CD-ROM. See the relevant sections for details. Flash RAM support through the use of memory cards, see below. BIOS stored on 512 KB ROM
The rest of the microchip consists of the on-die memory controller, which is shared by the CPU and the GPU and some additional logic concerned with memory access. With AMD being a founding member of and Sony a contributor to the HSA Foundation , the uncore of the PlayStation 4 supports several of the features promoted by the Heterogeneous ...

PlayStation 3's Cell CPU achieves a theoretical maximum of 204.8 GFLOPS in single precision floating point operations and up to 15 GFLOPS double precision. [1] The PS3 has 256 MB ([2]) of Rambus XDR DRAM, clocked at CPU die speed. [1] The PPE has 64 KB ([3]) L1 cache and 512 KB L2 cache, while the SPEs have 2 MB local memory (256 KB per SPE ...
The PlayStation 5 (PS5) is a home video game console developed by Sony Interactive Entertainment.It was announced as the successor to the PlayStation 4 in April 2019, was launched on November 12, 2020, in Australia, Japan, New Zealand, North America, and South Korea, and was released worldwide a week later.
I/O Memory: 2 MB EDO DRAM. CPU Core: Original PlayStation CPU (MIPS R3000A clocked at 33.8688 MHz or 36.864 MHz+PS1 GTE and MDEC for backwards compatibility with PS1 games) Automatically underclocked to 33.8688 MHz to achieve hardware backwards compatibility with original PlayStation format games. Sub Bus: 32-bit.
- John Taylor, AMD The PlayStation 4 uses an Accelerated Processing Unit (APU) developed by AMD in cooperation with Sony. It combines a central processing unit (CPU) and graphics processing unit (GPU), as well as other components such as a memory controller and video decoder. The CPU consists of two 28 nm quad-core Jaguar modules totaling 8 64-bit x86-64 cores, 7 of which are available for ...
The co-processor that normally manages the TLB-based MMU seems to be a custom effort by Sony and has no integrated memory. Both CPUs contain 16 KiB of two-way set associative instruction cache and data cache respectively. There is additionally 16 KiB of scratchpad RAM which, while faster than main RAM, is not nearly as fast as the integrated cache.
