Zen+ is the name for a computer processor microarchitecture by AMD.It is the successor to the first gen Zen microarchitecture, [3] and was first released in April 2018, [4] powering the second generation of Ryzen processors, known as Ryzen 2000 for mainstream desktop systems, Threadripper 2000 for high-end desktop setups and Ryzen 3000G (instead of 2000G) for accelerated processing units (APUs).
Zen 4c is a variant of Zen 4 featuring smaller Zen 4 cores with lower clock frequencies, power usage, reduced L3 cache per core, and is intended to fit a greater number of cores in a given space. Zen 4c's smaller cores and higher core counts are designed for heavily multi-threaded workloads such as cloud computing .
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.
