A few days ago we posted an article about the core i9-7960X being overclocked to 5.4 GHz on all 16 cores using liquid nitrogen (LN2). After this one of our readers (M17) alerted us to the fact that we hadn't reported on the recent AMD Threadripper overclocking event. At this event, two AMD staff members — Bill Alverson (Senior Product Development Engineer) and Amit Mehra (Principle Member of Technical Staff) — used liquid nitrogen to overclock to 5.2 GHz on all cores with a Threadripper 1950X.
The base turbo frequency for when all cores are loaded is 3.7 GHz, so this overclock gave a huge 40.5 percent increase in all-core clock speed on the pre-production motherboards used. While Ryzen performance tends to scale well with faster RAM speeds, memory was left at 2133 MHz during the overclocking to aid in system stability. The testers used AMD's software overclocking utility, Ryzen Master, for this benchmark record as it provided flexibility in not having to reboot frequently during the demonstration, although traditional BIOS overclocking works equally well too.
The results for Threadripper were very impressive with a Cinebench R15 multi-core score of 4122, although since this original test there is a 1950X clocked almost 200 MHz faster with a score of 4514 in the hwbot.org hall of fame. Intel's similarly priced i9-7900X overclocked using liquid nitrogen has a maximum multi-core score of 3333, due to having fewer cores at the same price point.
For those interested in Threadripper 1950X, we have a comprehensive 'first look' article on the Threadripper 1950X available on our site.
