Both models stretch up to 5.0 GHz when two cores are active. Better heat dissipation also facilitates the same impressive multi-core Turbo Boost clock rates as Core i9-9900K. The -9900KF comes with enthusiast-pleasing solder-based thermal interface material, which improves the chip's ability to dissipate thermal energy and augment overclocking. But just be sure your build includes an add-in GPU before spending money on the Core i9-9900KF. That's fine by us, since Intel's on-die graphics subsystems are notoriously unfit for even mid-level gaming. Integrated UHD Graphics GT2 (Base/Boost MHz)Īs mentioned, the Core i9-9900KF lacks an integrated UHD Graphics 630 engine, which Intel marks prominently on its packaging. The new "F" suffix indicates that this is a graphics-disabled part.ġ-2 Cores - 5.04 Cores - 4.8 8 Cores - 4.7ġ Core - 4.92 Core 4.8 4 Core 4.78 Core 4.6ġ Core - 4.62 Core - 4.54 Core 4.46 Core 4.3 It sports an unlocked ratio multiplier (denoted by the "K" suffix) for easy overclocking and support for up to 128GB of dual-channel DDR4-2666 memory. Just like that CPU, the -9900KF is manufactured on Intel's 14nm++ node. We covered the Core i9-9900K in our original review, so head there for deeper analysis of its architecture. Just be ready to pay an exorbitant price tag for the CPU, a beefy motherboard, high-end cooling, and a capable PSU. Otherwise, the chip offers nearly the same performance as Intel's graphics-equipped Core i9-9900K, meaning it serves up the best performance you can get on a mainstream desktop. Otherwise, as you can see in the picture above, both models are physically identical.Īs far as we can tell, the only reason to buy a -9900KF is immediate availability when you see it in stock. Splave lapped the chip, meaning he thinned the integrated heat spreader by sanding it down, to improve thermal transfer efficiency. Fortunately, we were able to borrow one from extreme overclocker Allen "Splave" Golibersuch for review. Intel isn't sampling the Core i9-9900KF to press. Intel Core i9-9900KF (Intel Core i9) at Amazon for $423.99 (opens in new tab).
