AMD Ryzen 7 3700X, Zen 2 architecture from 2019. 8 cores, 16 threads (with SMT), 3.6 GHz base with 4.4 GHz max boost, 32MB L3 cache, 65W TDP. Still one of the best all-around productivity and gaming CPUs on the AM4 platform — hits above its TDP weight because of Zen 2 IPC gains and the chiplet architecture. PCIe 4.0 support on X570/B550 boards makes it a strong pairing with modern NVMe SSDs. Pulled from a working desktop build.

Pulled from a working desktop build. IHS intact, no bent pins (AM4 pins on CPU side are straight and accounted for), thermal paste residue wiped before shipping. No retail box, no Wraith Prism cooler included.
AM4 socket. For full PCIe 4.0 support, requires X570 or B550 chipset motherboard. Also works on B450 and X470 boards with BIOS update (PCIe capped at 3.0 on those). No integrated graphics — discrete GPU required. 65W TDP means any mid-tier AM4 air cooler handles stock operation (Wraith Prism, Hyper 212, etc. all work). For Precision Boost Overdrive (PBO) or sustained all-core workloads, 240mm AIO recommended. Official memory support is DDR4-3200; higher speeds via XMP work on well-binned kits.
USPS Ground Advantage with tracking. Ships within 1 business day of cleared payment. Anti-static bag inside bubble mailer.
Pulled from a working desktop build. POSTs cleanly, detects as Ryzen 7 3700X at 3.6 GHz base, hits rated 4.4 GHz single-core boost, holds 4.0+ GHz all-core under load. I have not run a multi-hour Cinebench or Prime95 stress test; buyer is welcome to run additional testing upon receipt and return within 14 days if any stability issue is found.
AM4 socket. For PCIe 4.0 support (modern NVMe SSDs at full speed), pair with X570 or B550 board. B450/X470 boards work with a BIOS update but cap PCIe at 3.0. No integrated graphics — you need a discrete GPU. Good mid-tier cooler is sufficient for stock; AIO recommended for sustained all-core workloads or PBO tuning. Still an excellent mid-range option in 2026 for gaming, productivity, light content creation.
14-day return window. Item must be returned in original condition. Buyer pays return shipping.
