An AES instruction set includes instructions for key expansion, encryption, and decryption using various key sizes (128-bit, 192-bit, and 256-bit). The instruction set is often implemented as a set of instructions that can perform a single round of AES along with a special version for the last round which has a slightly different method.
As of 2019, AMD's Ryzen processors were reported to outsell Intel's consumer desktop processors. [185] At CES 2020 AMD announced their Ryzen Mobile 4000, as the first 7 nm x86 mobile processor, [vague] the first 7 nm 8-core (also 16-thread) high-performance mobile processor, and the first 8-core (also 16-thread) processor for ultrathin laptops ...
In 2020, AMD faced some criticism when it was announced on May 7 that its Zen 3-based Ryzen 5000 microprocessors would only be compatible with newer 500-series chipset AM4 motherboards. [41] [42] [43] This was explained as motherboard BIOS's sizes not being large enough to support the full range of AM4 socket processors.
Zen 4 is the name for a CPU microarchitecture designed by AMD, released on September 27, 2022. [4] [5] [6] It is the successor to Zen 3 and uses TSMC's N6 process for I/O dies, N5 process for CCDs, and N4 process for APUs. [7]
Two AMD Ryzen 9000 series microprocessors with Zen 5 architecture. Zen 5 is the name for a CPU microarchitecture by AMD, shown on their roadmap in May 2022, [3] launched for mobile in July 2024 and for desktop in August 2024. [4] It is the successor to Zen 4 and is currently fabricated on TSMC's N4X process. [5]
The string is specified in Intel/AMD documentation to be null-terminated, however this is not always the case (e.g. DM&P Vortex86DX3 and AMD Ryzen 7 6800HS are known to return non-null-terminated brand strings in leaves 80000002h-80000004h [160] [161]), and software should not rely on it.
