Amd ryzen 9 3900x outperforms i9

Australian overclocker jordan.hyde99 has set a new world record in wPrime 1024M using AMD's Ryzen 9 3900X processor. What's fascinating is the fact that AMD's processor was running at a much slower clock speed than the previous record bearer, the Intel Core i9-7920X.

Ryzen 9 3900X sets the world record in wPrime running at 5, 625 MHz

Both the Ryzen 9 3900X and the Intel Core i9-7920X are equipped with 12 cores and 24 threads, so both chips are in the same condition in terms of number of cores. The former is based on AMD's Zen 2 microarchitecture and features a 3.8 GHz base clock and 4.6 GHz boost clock, while the latter uses Intel's Skylake microarchitecture and clocks with a 2 base, 9 GHz and 4.4 GHz maximum.

Jordan.hyde99 overclocked his Ryzen 9 3900X at 5, 625 MHz with the use of his good friend Liquid Nitrogen. With this processor, he was able to finish the wPrime 1024M in 35 seconds and 517 milliseconds to remove the crown from the Core i9-7920X.

In comparison, the Core i9-7920X held the record at 35 seconds and 693 milliseconds, while using 5, 955 MHz overclocking with the same type of liquid nitrogen cooling.

Although the Ryzen 9 3900X only managed to outperform the Core i9-7920X by a negligible margin (less than one percent), the big advantage is the speed of the clock. The Ryzen 9 3900X was able to match the Core i9-7920X's score while running at a 5.8% lower operating clock.

This is a testament to the fact that Zen 2 instructions per cycle (IPC) are superior to Skylake's, and subsequent microarchitectures based on the same design, in many workloads.
