CPU-Z is more comprehensive in virtually all areas compared to the tools provided in the Windows to identify various hardware components, and thus assists in identifying certain components without the need of opening the case; particularly the core revision and RAM clock rate. It also provides information on the system's GPU.
CPUID must be issued with each parameter in sequence to get the entire 48-byte ASCII processor brand string. [159] It is necessary to check whether the feature is present in the CPU by issuing CPUID with EAX = 80000000h first and checking if the returned value is not less than 80000004h.
CPUID model numbers are 30h-3Fh. AMD Excavator Family 15h (4th-gen) – fourth-generation Bulldozer (Final optimisation). CPUID model numbers are 60h-6Fh, later updated revisions have model numbers 70h-7Fh. AMD Zen – family of microarchitectures. The successor to Bulldozer. Included in the Ryzen and Epyc CPU lines.
This article gives a list of AMD microprocessors, sorted by generation and release year.If applicable and openly known, the designation(s) of each processor's core (versions) is (are) listed in parentheses.
AVX-512 are 512-bit extensions to the 256-bit Advanced Vector Extensions SIMD instructions for x86 instruction set architecture (ISA) proposed by Intel in July 2013, and first implemented in the 2016 Intel Xeon Phi x200 (Knights Landing), [1] and then later in a number of AMD and other Intel CPUs (see list below).
The initial Ryzen CPUs could be crashed by a particular sequence of FMA3 instructions, but updated CPU microcode fixes the problem. [23] July 2019: AMD Zen 2 and later Ryzen processors don't support FMA4 at all. [24] They continue to support FMA3. Only Zen 1 and Zen+ have unofficial FMA4 support.
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]
Various CPU-based cryptocurrency miners (like pooler's cpuminer for Bitcoin and Litecoin) use AVX and AVX2 for various cryptography-related routines, including SHA-256 and scrypt. FFTW can utilize AVX, AVX2 and AVX-512 when available. LLVMpipe, a software OpenGL renderer in Mesa using Gallium and LLVM infrastructure, uses AVX2 when available.
