AMD Threadripper vs. Intel Core i9 CPUs Clock for Clock

By: Steven Bassiri | Editorials in CPUs, Chipsets & SoCs | Posted: Oct 22, 2017 4:46 pm

The CPUs




The Threadripper 1950X is clocked to 4.0GHz with a 100MHz base clock. Memory XMP is set on the G.Skill kit to 3200MHz C14, and that also increases the NB frequency (Infinity Fabric) to the same speed as the RAM, so from 1066 to 1600, which is a 50% increase. The CPU is fed 1.325v with LLC ON, there is a fan running full speed over the VRMs, and all radiator fans are going full speed at all times. I use the highest ranked motherboard from ASRock for the AMD Threadripper System and the Skylake-X system.





The Intel 7960X is clocked up to 4.0GHz using multiplier only overclocking. Memory speed is increased to 3200MHz per XMP, using the same exact kit that was used for the Threadripper testing. The Threadripper system also had its infinity fabric increased in speed by 50%, so I went ahead and overclocked the mesh speed from 2.4GHz to 3.2GHz, which is a 33% increase. An input voltage of 2.1v was used, and LLC was turned on. A fan was blowing right over the VRMs, and the radiator fans were always blowing full speed.
