Summit Ridge processors
Zen Summit (1st Gen)
— AMD CPUs 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 enhancements introduced with the Zen chips is the SMT (simultaneous multithreading technology), essentially AMD's answer to Intel's Hyper-threading. Also from the features of the architecture, we 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 CPUs; their feature is the lack of built-in graphics cores.
