AMD
AMD Ryzen 9 5950X
The AM4 flagship: 16 Zen 3 cores and 32 threads with the highest boost clock of the family at 4.9 GHz, all inside a 105 W TDP. It exists for sustained multithreaded work — rendering, simulation, large compiles — on a mainstream dual-channel platform.
Pros
- 16 cores / 32 threads, the most any AM4 socket CPU will ever offer
- 4.9 GHz boost is the highest clock in the Zen 3 desktop line
- 64 MB L3 and PCIe 4.0
- Remarkably efficient per core at 105 W TDP given the core count
- Bins highly, so it responds well to PBO and Curve Optimizer tuning
Cons
- $799 launch price, and used prices have stayed high because there is no AM4 replacement
- Cross-CCD latency means gaming performance is no better than a 5800X and below a 5800X3D
- Sustained all-core loads hit the 142 W PPT quickly and demand a 240 mm AIO or large tower cooler
- No cooler included and no integrated graphics
