6.3GHz Ryzen 9 9700X beats 7.1GHz Core i9-14900KF in AVX liquid nitrogen test

Published:

LN2 Overclocker Tax benches took the AMD Ryzen 7 9700X to up-to-date heights, beating the 7.1 GHz Core i9-14900KF in OCCT with a clock deficit of almost 1 GHz. The overclocker broke the OCCT AVX benchmark world record with a score of 269.35 points on AMD’s latest 8-core Zen 5 chip.

The world record was achieved at just 6.318 GHz on the Ryzen 7 9700X. To get the Zen 5 chip to this speed, SkatterBencher used a number of techniques, rather than manually entering a multiplier and voltage. Skatterbencher used a combination of BCLK overclocking, Precision Boost Overdrive, AMD’s Curve Optimizer (with positive offset), and Curve Shaper to allow Ryzen’s Precision Boost algorithm to run at well over 6 GHz on liquid nitrogen.

With a score of 269.35 points, the Ryzen 7 9700X outperformed Intel’s flagship Core i9-14900KF in the same test, clocked at 7.1 GHz on liquid nitrogen. The Core i9’s score was 14 points lower than its Zen 5 counterpart, despite running at an 800 MHz higher clock speed.

However, in the SSE version of the benchmark, the 9700X was not as robust. In the SSE OCCT benchmarks, the 9700X was unable to outperform the 14900KF, scoring 127.79 points, 8.76 points behind the Raptor Lake CPU.

In other benchmarks, the Ryzen 7 9700X achieved 1003 points in the CPU-Z 2017.1 single-core test and 10805 points in the multi-core test. Skatterbencher was also able to boost the 9700X to 6.8 GHz by disabling SMT, which allowed the 9700X to achieve the highest CPU frequency in the CPU-Z validator in the last 12 months. In Geekbench 6, SkatterBencher was able to achieve a single-core score of 3902 points and a multi-core score of 21135 points at 6.3 GHz.

The LN2 SkattterBencher results show the strengths of AMD’s Zen 5 architecture, namely its more effective AVX-512 optimizations. Zen 5 is the first AMD architecture to boast full AVX-512 pipeline bandwidth, increasing AVX-512 performance over Zen 4. Intel, on the other hand, does not have any AVX-512 support on its 13th or 14th generation chips, which relegates the i9-14900KF to using AVX and/or AVX2 instructions in the OCCT test. This is certainly why the 9700X was able to outperform the i9-14900KF at such a severe clock speed disadvantage.
