Intel Core i9-11900K With DDR4 Memory Dethrones Core i9-14900KS With DDR5 Memory In PYPrime Latency Benchmark World Record
The Intel Core i9-11900K, a three-year-old CPU, running on DDR4 memory has set a new world record, dethroning the 14900KS with DDR5.
Old Intel Core i9-11900K CPU With DDR4 Memory Sets New World Record, Outshines New Core i9-14900KS With DDR5 Memory
The Intel Rocket Lake CPUs have been regarded as a "Waste of Sand" bringing in small uplifts in performance while regressing in the core count compared to the generation that was released prior. However, it looks like overclockers have found a new purpose for these chips & when tuned right, they can surpass even the best chips available on the market today.

The new world record memory overclocking feat comes from legendary overclocker, SPLAVE aka Allen Matthew, who decided to give the Intel Core i9-11900K (Rocket Lake) CPU a run on the Z590 OC Formula motherboard from ASRock. This motherboard features support for DDR4 memory & comes tuned for memory overclock with its dual DIMM design. The benchmark used was PYPrime which calculates the latency performance and the 32B run was used.
The previous record was achieved by renowned overclocker, SAFEDISK, who used an Intel Core i9-14900KS CPU running at 8.37 GHz (across 8 P-Cores) and a pair of G.Skill Trident Z5 RGB memory kits running at DDR5-9306 (CL32-47-42-34-2T). The previous world record was achieved in 1 minute, 37 seconds, and 596ms.
But SPLAVE decided he could do better while using older hardware. For the OC session, the Intel Core i9-11900K CPU was tuned to 6.957 GHz, and the pair of G.Skill Trident Z DDR4 memory was overclocked to DDR4-3914 (CL12-11-11-18-1T) speeds. With these speeds, the overclocker finished the benchmark in 1 minute, 37 seconds, and 311ms. This was just 285ms faster but when we ran the numbers on the overall latency figures, the Core i9-11900K achieved around 10% lower latency which is essential for this benchmark.
