AMD Ryzen 3 3100
A $99 Zen 2 quad-core with SMT and PCIe 4.0, built from a chiplet with two cores enabled per CCX so its 16 MB of L3 is split 8+8. It was the cheapest ticket onto a B550 board, and today it is a stopgap chip rather than something to build around.
Pros
- 8 threads and PCIe 4.0 for a $99 launch price
- Strong overclocker for the money — 4.2-4.3 GHz all-core is common on the bundled cooler
- 65 W TDP / 88 W PPT with a Wraith Stealth included
- Official DDR4-3200 support, the same as the rest of the Zen 2 desktop line
- Supported on 400- and 500-series boards with a current BIOS, so a Zen 3 upgrade stays open
Cons
- 2+2 core layout across two CCXes — the 3300X's single 4-core CCX is measurably faster at the same clock
- Four cores is thin for 2026 CPU-heavy games, streaming, or anything with a background workload
- 3.9 GHz boost is the lowest of the Zen 2 desktop parts
- Short production run; genuinely scarce new or used
Below average
