Intel’s 9th generation lineup has dozens of variants, from the low power “T” chips to the
As of now, nothing (other than the name) is known about this supposed KFC chip. The name was spotted on the change-log for AIDA64 which is a popular CPU benchmarking tool. This isn’t the first time such software has given away info on an unannounced SKU. The FFXV and AoTS benchmark databases have repeatedly been used to leak info on unannounced GPUs, for example, the RTX 2060 as well as the GTX 1660 Ti.
NVIDIA: DLSS Quality will get Better With Time
AMD Ryzen 3000 CPUs and Radeon Navi 7nm GPUs to Launch on 7th July
Going by the name, i9-9900KFC, three things can be said with a fair bit of certainty. If the CPU does actually exist, it will be an overclocked part, lacking the iGPU (that’s what the K and F stand for). However, the C is a bit confusing. Back in the day, the Broadwell lineup used the designation “C” for improved on-board graphics, but that doesn’t make sense as this part is supposed to ditch it.
Intel might offer eDRAM on its high-end 9th-gen CPUs, but given the fact that they are lacking the iGPU it doesn’t quite add up. If this leak turns out to be legit, it will be interesting to see what Intel has to say about the effects of the extra eDRAM on performance.

Another theory I saw was that the “C” could stand for Cache, as in reduced or increased cache size. Increased for performance or decreased to salvage parts with a partially defective L3 cache.
