At first sight, the Intel Core i9-9900KFC seems to be an unlocked 8-core, 16-thread processor that does not feature an integrated graphics card. However, Intel previously used the "C" suffix for chips with eDRAM cache for the higher-end Iris Pro integrated graphics parts, so this new chip is a mystery for now.
