Master of his craft: Splave breaks another 12-core record with AMD Ryzen 9 3900XT

It's only been a little over 10 days since American overclocker Splave posted a pair of results that earned him two gold medals in the 12-core category. Typically, after such a productive bench session, Splave takes a break for about a month. Not this time, though: last night, a much more significant achievement appeared on the enthusiast's profile.

As you've probably guessed, the American continued exploring the overclocking potential of AMD's new Ryzen 9 3900XT 'Matisse Refresh' processor. This time, he tackled the Cinebench R15 benchmark.

By pushing the Ryzen 9 3900XT to 5775MHz — about 65MHz higher than his previous run — Splave secured two more gold medals: one in the specific chip's category and another in the overall 12-core ranking:

This is an absolutely stunning result! The previous 12-core record had stood for just over a year, held by Korean overclocker safedisk.

According to CPU-z and HWBot BenchMate monitoring, the processor core voltage hit 1.550 volts — the same voltage Splave used in his last bench session. This leads to a couple of conclusions: either he's using a different CPU sample for this experiment, or, more likely, Cinebench R15 stresses the processor less than HWBOT x265 Benchmark – 4k and Geekbench3 – Multi Core. Although, calling "HWBOT x265 Benchmark — 4k" 'light' on the CPU would be a flat-out lie.

Splave's test bench consisted of these components:

• Motherboard — ASRock X570 AQUA (Bios P1.40D)

• RAM — 2x 8GB G.SKILL TridentZ F4-3800C14-8GTZN

• Thermal paste — Thermal Grizzly Kryo Lhe

• Power supply — Enermax Maxtytan 1250w

• Operating system — Windows 10 x64
