The leak comes from chi11eddog on Twitter, which has a reputation for leaking new MSI products in particular. Their latest post goes into detail about a new addition for the MAG B660M Mortar motherboard called a Renesas clock generator. This module, as noted in the above photo, can apparently force a BCLK overclock on any non-K Intel 12th gen CPU. Intel locks users out of overclocking as a means of product segmentation, so this new feature would be a game changer. The leak also mentions PCIe 5.0 support.
They even provided some testing data for a Core i5-12400 six-core processor, which managed an all-core frequency of 5.1 GHz. This is a major frequency uplift over the stock limit of 4.4 GHz, which also only applies to 1-2 cores at best.
26% more performance in tests
Chi11eddog also demonstrated the performance uplift difference with a synthetic Cinebench R23 benchmark, though that information has since been removed from the original tweet. Fortunately, WCCFTech was quick to snag the original screenshots. The stock CPU settings yielded a score 12,525. Once overclocked to 5.1 GHz, the score jumped to an impressive 15,843 points. That’s a performance difference of 26%, which allows this $199 CPU to compete with far more expensive processors. The same method could of course also be done on any other non-K CPU.
Six-core CPUs are great for gaming, even with modern titles. If this new MSI MAG B660M Mortar motherboard comes to market with this feature, it will offer a fantastic value proposition for anyone looking to build a new PC on a budget. Those savings could then be spent elsewhere, such as on a better graphics card.
The ability to easily overclock a non-K 12th gen Intel CPU would be welcome by many. Whether Intel would allow MSI, a major partner of Intel, to sell something like this is another matter.
