Zen Summit CPU computers

Zen Summit (1st gen)

— AMD processors belonging to the first generation of chips based on the Zen microarchitecture; the full family name is Summit Ridge.

The Zen microarchitecture was released in 2017 as a completely independent development (rather than an improvement on older solutions). One of the key improvements introduced with Zen chips is SMT concurrent multithreading technology, essentially AMD's answer to Intel's Hyper-threading. Also of the architectural features, one can note the 14 nm process technology, a dedicated floating point unit in each core, and a level 3 cache up to 16 MB. Specifically, the Summit Ridge chips replaced the Excavator processors; their feature is the lack of built-in graphics cores.
