It has been a few weeks since Intel launched its new range of processors, known as the Core Ultra 200S series. This includes the new flagship 285K, which failed to provide the performance uplift many people were looking forward to compared to the previous 14th-generation processors. It is especially disappointing in gaming, where AMD’s new 9800X3D beats it by 20%. It’s safe to say that many reviewers weren’t too impressed, Gamers Nexus leading with “Get it together, Intel” says it all.

In our Intel Core Ultra 285K review, we noted that while it is “a great processor,” it still falls slightly behind the last-gen 14900K in some scenarios. In terms of what’s going for it, we’d have to pick out great temperatures and impressive multi-core performance – the latter we’ll be discussing today off the back of new overclocking benchmarks posted online.

Intel Core Ultra 9 285K extreme overclock

Recently, CENS, a known overclocking enthusiast (and OC World Cup Champion), ran a live stream on his YouTube channel to give the 285K a run for its money. While it didn’t go perfectly smoothly with crashes and perhaps the usual hurdles you’d expect when going to the extreme to overclock, he did end up with a new high score.

According to benchmark tests on Cinebench R23 with some extreme overclocking with liquid nitrogen cooling, the 285K was able to score a massive 61,154 points in multi-core. According to the report, the chip ran at a maximum clock speed of 6983,33 MHz, which is more or less 7 GHz. Compare this to the current Cinebench R23 Multi Core with BenchMate records, and you’ll see that it’s ahead of the competition. It’s the very first 61K score and beats out previous 60K records, including one from CENS.

For further reference, outside of overclocking records, that’s well above the current top multi-core score on the Cinebench R23 database, which tops out at 42,597 for the Core i9-14900KS.

While these kinds of conditions are far beyond what your average user will be dealing with, it does show the potential of the 285K when pushed to its limits. In our synthetic CPU tests without overclocking, the 285K reached a score of 41,536 in the Cinebench R23 multi-core benchmark. This puts it close to the 14900K at 39,973 and AMD’s 9950X at 40,938.
