Intel’s Core i5-12400 is going to be a very interesting part. Unlike the Core i5-12600K which is expected to have six “Golden Cove” P cores and four “Gracemont” E-cores, this chip is going to be fully comprised of P cores and will lack any E cores. So you’ll have a 6-core, 12-thread P-core only part with 1.25 MB of dedicated L2 cache per core, and 18 MB of shared L3 cache.
A user on Chinese social media posted an alleged Cinebench R20 result of the chip, which it scores 659 in the single-threaded test and 4784 in the multi-threaded test. WCCFTech took this data and compared it to known performance numbers of popular chips and the i5-12400 ends up being slightly ahead of the Ryzen 5 5600X.
The Ryzen 5 5600X is currently a $300 part, while the Core i5-11400 is expected to be $190, even with a 10-15% price hike it will be cheaper than the Ryzen 5 5600X. The really only drawback to the chip is that it will have a locked BCLK multiplier and lower clock speeds of only 4 GHz.
