AMD · Ryzen 3 · 2020 · AM4
The AMD Ryzen 3 3100 is a desktop processor with 4 cores, released in 2020 at an MSRP of $99. It is part of the Ryzen 3 lineup, using the Ryzen 3000 platform, and fits the AM4 socket. Internally, it is built on the "Zen 2" architecture. Thanks to AMD Simultaneous Multi-Threading (SMT), each core can handle two instruction streams simultaneously, yielding a total of 8 threads for improved parallelism. The Ryzen 3 3100 has a base clock of 3.6 GHz and can boost up to 3.9 GHz depending on workload and thermal headroom. AMD manufactures the "Zen 2" silicon on a 7nm process node. The multiplier is unlocked, making overclocking straightforward. This processor supports DDR4 memory. ECC memory is supported, provided the motherboard enables it. With a TDP of 65W, the Ryzen 3 3100 is an efficient chip suitable for modest cooling solutions. This processor has no integrated graphics — a discrete GPU is required. The cache hierarchy consists of 64KB/core of L1, 2MB of L2, and 16MB of L3 cache.
Entry-level Zen 2. Unlike the 3300X which places all 4 cores on one CCX, the 3100 splits them 2+2 across two CCXs — resulting in higher cross-core latency and slightly lower gaming performance at the same price.
