About AMD Athlon X4 870K

The AMD Athlon X4 870K is a quad‑core, four‑thread processor built on a 28 nm process for the FM2+ socket. Its base frequency of 3.90 GHz and boost up to 4.10 GHz give it a strong single‑core foundation, evident in the 411‑point Cinebench R23 single‑core score. Multi‑core workloads benefit from the full 4 cores, delivering 2,917 points in Cinebench R23 multicore and 1,225 points in the older R20 suite. Power consumption stays modest at a 95 W TDP, which aligns with the typical thermal envelope of mainstream FM2+ parts. The cache hierarchy 64 KB L1 per core, 256 KB L2 per core, and a shared 2 MB L3 helps keep latency low for both gaming and productivity tasks.

The 870K shines in applications that favor high clock speeds over massive parallelism, such as older titles, light content creation, and office suites. Geekbench places the chip at 1,205 points in the multi‑core test and 468 points in single‑core, confirming its balanced performance envelope. For users seeking a cost‑effective upgrade on FM2+ boards, AMD's 870K provides enough headroom for 1080p gaming when paired with a mid‑range GPU. Its efficient thermal design also makes it suitable for compact builds where fan noise and heat dissipation are concerns. The following list highlights the best use cases for this processor.
