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 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, dedicated floating point unit in each core, and 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.
