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 Ryzen family is an x86-64 microprocessor family from AMD, based on the Zen microarchitecture.The Ryzen lineup includes Ryzen 3, Ryzen 5, Ryzen 7, Ryzen 9, and Ryzen Threadripper with up to 96 cores.
All the CPUs support 28 PCIe 5.0 lanes. 4 of the lanes are reserved as link to the chipset. Includes integrated RDNA2 GPU with 2 CUs and base, boost clock speeds of 0.4 GHz, 2.2 GHz. L1 cache: 80 KB (48 KB data + 32 KB instruction) per core. L2 cache: 1 MB per core. Fabrication process: TSMC N4 FinFET (N6 FinFET for the I/O die).
AMD Zen 4 Family 19h – fourth generation Zen architecture, in 5 nm process. [5] Used in Ryzen 7000 consumer processors on the new AM5 platform with DDR5 and PCIe 5.0 support. Adds support for AVX-512 instruction set. AMD Zen 5 Family 1Ah – fifth generation Zen architecture, in 4 nm process. [6] Adds support for full-width AVX-512 pipeline.
The model numbers of the Phenom line of processors were changed from the PR system used in its predecessors, the AMD Athlon 64 processor family. The Phenom model numbering scheme, for-later released Athlon X2 processors, is a four-digit model number whose first digit is a family indicator. [12]
Zen 4 is the first AMD microarchitecture to support AVX-512 instruction set extension. Most 512-bit vector instructions are split in two and executed by the 256-bit SIMD execution units internally. The two halves execute in parallel on a pair of execution units and are still tracked as a single micro-OP (except for stores), which means the ...
AMD Athlon X4 is a series of budget AMD microprocessors for personal computers. These processors are distinct from A-Series APUs of the same era due to the lack of iGPUs. These processors are distinct from A-Series APUs of the same era due to the lack of iGPUs.
4 Bulldozer modules within FX-8 series, 3 in FX-6 series, and 2 in FX-4 series. All models support up to 4 DIMMs of DDR3-1866 memory. Bulldozer Core (Zambezi, 32 nm)
