LN2 overclocker Skatterbencher has taken AMD's Ryzen 7 9700X to new heights, beating a 7.1GHz Core i9-14900KF in OCCT with nearly a 1 GHz deficit clock speed. The overclocker broke the OCCT AVX benchmark world record with a score of 269.35 points on AMD's latest Zen 5 8-core chip.
The world record-breaking result was achieved at just 6.318 GHz on the Ryzen 7 9700X. To get the Zen 5 chip to that speed, SkatterBencher used a host of techniques, rather than inputing a manual multiplier and voltage. Skatterbencher used a combination of BCLK overclocking, Precision Boost Overdrive, AMD's Curve Optimizer (with a positive offset), and Curve Shaper to enable Ryzen's Precision Boost algorithm to run at well over 6GHz on liquid nitrogen.
With a score of 269.35 points, the Ryzen 7 9700X outscored Intel's flagship Core i9-14900KF in the same benchmark, clocked at 7.1GHz on liquid nitrogen. The Core i9's score was 14 points lower than the Zen 5 equivalent, despite operating at an 800MHz higher clock speed.
However, in the SSE version of the benchmark, the 9700X wasn't as strong. In OCCT's SSE benchmarks , the 9700X was not able to outperform the 14900KF, featuring a score of 127.79 points, 8.76 points behind the Raptor Lake CPU.
In other benchmarks, the Ryzen 7 9700X was able to reach 1,003 points in CPU-Z 2017.1's single-core benchmark and 10,805 points in the multi-core counterpart. Skatterbencher was also able to push the 9700X to 6.8GHz by disabling SMT, enabling the 9700X to hit the highest CPU frequency on the CPU-Z validator over the last 12 months. In Geekbench 6, SkatterBencher was able to hit a single core result of 3,902 points and a multi-core result of 21,135 points at 6.3 GHz.
SkattterBencher's LN2 scores show the strengths of AMD's Zen 5 architecture, namely its beefier AVX-512 optimizations. Zen 5 is the first AMD architecture to boast a full throughput AVX-512 pipeline, boosting AVX-512 performance over Zen 4. Intel on the other hand does not have any AVX-512 support on its 13th or 14th Gen chips, relegating the i9-14900KF to using AVX and/or AVX2 instructions for the OCCT test. This is most certainly the reason why the 9700X was able to outpace the i9-14900KF at such a severe clock speed disadvantage.
