About AMD Ryzen 9 3950X

The Ryzen 9 3950X from AMD, built on the 7 nm Zen 2 “Matisse” die, delivers a massive 16‑core/32‑thread package that still feels at home in a mainstream AM4 socket. Its base clock of 3.5 GHz and boost up to 4.7 GHz give it the bandwidth to crush multi‑threaded workloads, as evidenced by a 32,793‑point score in Cinebench R23’s multi‑core test. Power‑draw stays reasonable for a chip of this size, with a 105 W TDP that typically idles below 50 W and only spikes to around 200 W under full load, letting most 600 W PSUs handle it without breaking a sweat. The 64 MB of L3 cache and support for DDR4‑3200 memory create a fast, low‑latency subsystem that keeps the cores fed, which is why the 3950X consistently posts over 10 k points in both Geekbench multi‑core and 3DMark’s 16‑thread test. For creators, this processor is a beast in video rendering, 3D modelling, and scientific simulations, with Cinebench R20 multi‑core hitting 13,773 points and 3DMark’s max‑thread benchmark reaching 10,719 points. Gamers who also stream or run background encoding will appreciate the chip’s ability to keep frame rates high while handling a separate encoding thread, making it a go‑to choice for a high‑performance rig. In short, AMD’s 16‑core flagship offers a rare blend of raw horsepower, efficient power envelope, and a mature platform that still benefits from the latest B550 and X570 chipset features.

  1. Zen 2 “Matisse” architecture with 7 nm process delivering high IPC and efficiency.
  2. Base/boost frequencies of 3.5 GHz and 4.7 GHz provide strong single‑ and multi‑core performance.
  3. 105 W TDP balances power consumption with the ability to sustain high boost under load.
  4. 64 MB L3 cache coupled with DDR4‑3200 support ensures low latency memory access.
  5. Benchmark scores: 32,793 (Cinebench R23 multi), 13,773 (Cinebench R20 multi), 10,719 (3DMark max‑threads).
  6. Ideal for content creation, 3D rendering, scientific workloads, and high‑frame‑rate gaming with streaming.
