Oops: Reliable leakers have assembled a clear picture of Intel's upcoming 14th-generation CPUs over the last few weeks. However, final confirmation of what everyone suspects has accidentally come from one of the company's hardware partners – the new processors likely won't significantly improve performance over the 13th generation.

A recent livestream from MSI unintentionally revealed some final details on Intel's next generation of CPUs. The video is now private, but the screenshot (below) confirms core counts, expected performance ranges, and the lineup's name – Raptor Lake-S Refresh.

The accident vindicates leakers who have for weeks suggested that the revision only offers minimal gains over the current Raptor Lake processors. With the same architecture, core counts, and 10nm Intel 7 process, the Intel 14th gen processors are, on average, only about three percent faster than their predecessors.

The sole exception is the i7-14700K, which gains four efficiency cores for a 17 percent performance increase. However, benchmark leaks indicate that the i5-14600K could be a fair upgrade over its 13th-gen counterpart.

A comparatively minor mistake from Asus further confirms the new generation's label. Prolific leaker Momono discovered that the webpage advertising the Asus Z790, H700, and B760 motherboards mentions that they support the 14th-gen Raptor Lake-S Refresh alongside the 13th and 12th generations. Hovering the cursor over the tab in Firefox or Safari reveals the lengthy title, while users of other browsers can see it in the page's HTML source.

Recent BIOS updates from Asus, MSI, Gigabyte, and Asrock confirm that the new CPUs support currently available motherboards with Intel's LGA-1700 socket, suggesting they will be a relatively cheap upgrade. Due to this and the minor horsepower uplift, Raptor Lake-S Refresh will likely be more worthwhile for users still running 12th-gen Alder Lake processors.

Raptor Lake owners will see a more considerable leap from Arrow Lake – the 15th generation coming in the second half of next year. The latest information on those CPUs suggests significantly more cache and dramatically improved integrated graphics performance. However, the required motherboard upgrades and DDR5 RAM make Alder Lake a costlier investment, better suited to a system rebuild.

Intel hasn't revealed when Raptor Lake-S Refresh will launch. However, the first members of the lineup – likely only the unlocked K-series processors – could appear in late October, according to earlier rumors. Meanwhile, Locked non-K variants might emerge at CES 2024.
