Hey everyone,
With the recent release of the new Zen 5 and Raptor Lake Refresh CPUs, I've been seeing a lot of hype about their overclocking potential. I wanted to create a thread to consolidate benchmark results and discuss real-world overclocking performance.
I've been testing the new Intel Core i9-14900K and the AMD Ryzen 9 7950X3D with my custom loop cooling setup. So far, I've managed to push the 14900K to a stable 6.2 GHz all-core on the P-cores with ~1.45V, though temperatures under heavy load (like Prime95) can still hit 90°C. Cinebench R23 scores are sitting around 42000 multi-core and 2200 single-core.
For the 7950X3D, I've focused on undervolting and slight frequency bumps on the non-3D V-Cache cores. I've achieved a stable PBO limit of ~5.3 GHz on the performance cores with a negative offset of -25mV. Cinebench R23 scores are around 38000 multi-core and 2000 single-core. The 3D V-Cache cores remain untouched for gaming benefits.
Here are some key benchmarks I've run:
- Cinebench R23:
- i9-14900K (6.2 GHz OC): MC 42000 / SC 2200
- R9 7950X3D (5.3 GHz OC): MC 38000 / SC 2000
- 3DMark Time Spy:
- i9-14900K (6.2 GHz OC): CPU Score ~18500
- R9 7950X3D (5.3 GHz OC): CPU Score ~17800
- Gaming Benchmarks (Cyberpunk 2077 @ 1080p Ultra):
- i9-14900K (6.2 GHz OC): Avg FPS ~210
- R9 7950X3D (5.3 GHz OC): Avg FPS ~205
It's interesting to see how the architectures differ in their overclocking headroom. The Intel chip definitely has raw frequency potential, but the power draw and heat are significant. The AMD chip's efficiency, especially with undervolting, is impressive, although the 3D V-Cache configuration presents its own set of tuning challenges.
