The vector engine in Zen 5 features 4 floating point pipes compared to 3 pipes in Zen 4. Zen 4 introduced AVX-512 instructions. AVX-512 capabilities have been expanded with Zen 5 with a doubling of the floating point pipe width to a native 512-bit floating point datapath. The AVX-512 datapath is configurable depending on the product.
The AVX-512 instructions are designed to mix with 128/256-bit AVX/AVX2 instructions without a performance penalty. However, AVX-512VL ... Zen 5: [34] AVX-512 F, CD ...
For CPUs supporting AVX10 and 512-bit vectors, all legacy AVX-512 feature flags will remain set to facilitate applications supporting AVX-512 to continue using AVX-512 instructions. [ 41 ] AVX10.1/512 was first released in Intel Granite Rapids [ 41 ] (Q3 2024) and AVX10.2/512 will be available in Diamond Rapids .

Epyc (stylized as EPYC) is a brand of multi-core x86-64 microprocessors designed and sold by AMD, based on the company's Zen microarchitecture.Introduced in June 2017, they are specifically targeted for the server and embedded system markets.
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.
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 ...
iGPU uses the RDNA 3.5 microarchitecture. NPU uses the XDNA 2 AI Engine (Ryzen AI). Both Zen5 and Zen5c cores support AVX-512 using a half-width 256-bit FPU. L1 cache: 80 KB (48 KB data + 32 KB instruction) per core. L2 cache: 1 MB per core. Fabrication process: TSMC N4P FinFET.
