In terms of overall gaming performance, the Intel Core i9-9900KF 8-Core 3.6GHz is massively better than the Intel Core i7-9700KF 8-Core 3.6GHz when it comes to running the latest games. This also means it will be less likely to bottleneck more powerful GPUs, allowing them to achieve more of their gaming performance potential.

Both the Core i9-9900KF 8-Core 3.6GHz and the Core i7-9700KF 8-Core 3.6GHz were released at the same time, so are likely to be quite similar.

Both CPUs exhibit very powerful performance, so it probably isn't worth upgrading from one to the other, as both are capable of running even the most demanding games at the highest settings (assuming they are accompanied by equivalently powerful GPUs).

The Core i9-9900KF 8-Core and the Core i7-9700KF 8-Core both have 8 cores. Games are not yet able to harness this many cores, so it is probably excessive if you mean to just run the latest games; however, if you intend on running a server with this CPU, it would seem to be a decent choice.

The Core i9-9900KF 8-Core has 8 more threads than the Core i7-9700KF 8-Core. The Core i7-9700KF 8-Core has one thread per physical core, whereas the Core i9-9900KF 8-Core uses hyperthreading and has 2 logical threads per physical core.

Multiple threads are useful for improving the performance of multi-threaded applications. Additional cores and their accompanying thread will always be beneficial for multi-threaded applications. Hyperthreading will be beneficial for applications optimized for it, but it may slow others down. For games, the number of threads is largely irrelevant, as long as you have at least 2 cores (preferably 4), and hyperthreading can sometimes even hit performance.

More important for gaming than the number of cores and threads is the clock rate. Problematically, unless the two CPUs are from the same family, this can only serve as a general guide and nothing like an exact comparison, because the clock cycles per instruction (CPI) will vary so much.

The Core i9-9900KF 8-Core and the Core i7-9700KF 8-Core are from the same family of CPUs, and thus their clock speeds are directly comparable. That isn't particularly helpful, however, as the Core i9-9900KF 8-Core and the Core i7-9700KF 8-Core provide identical clock rates and thus extremely similar performance.

Aside from the clock rate, the next-most important CPU features for PC game performance are L2 and L3 cache size. Faster than RAM, the more cache available, the more data that can be stored for lightning-fast retrieval. L1 Cache is not usually an issue anymore for gaming, with most high-end CPUs eking out about the same L1 performance, and L2 is more important than L3 - but L3 is still important if you want to reach the highest levels of performance. Bear in mind that although it is better to have a larger cache, the larger it is, the higher the latency, so a balance has to be struck.

The maximum Thermal Design Power is the power in Watts that the CPU will consume in the worst case scenario. The lithography is the semiconductor manufacturing technology being used to create the CPU - the smaller this is, the more transistors that can be fit into the CPU, and the closer the connections. For both the lithography and the TDP, it is the lower the better, because a lower number means a lower amount of power is necessary to run the CPU, and consequently a lower amount of heat is produced.

Both the Core i9-9900KF 8-Core and the Core i7-9700KF 8-Core have the same TDP of 95 Watts, and were created with the same manufacturing size of 14 nm, which means they will affect your yearly electricity bill about equally.

CPU Mini Review

Mini ReviewThe Core i9-9900KF 8-Core 3.6GHz is a top-end CPU based on Intel's 9th Gen 14nm, Coffee Lake refresh microarchitecture. It offers 8 physical cores (8 logical) initially clocked at 3.6GHz, which may go up to 5.0GHz using Turbo Boost. The 9900KF is almost identical to the Core i9-9900K aside from the lack of integrated graphics. It has an unlocked multiplier and can, therefore, be overclocked using traditional methods. It has 16MB of SmartCache. Intel SmartCache refers to the architecture that allows all cores to dynamically share access to the last level cache. Level 3 cache is a static memory bank of a processor and it is used to feed it instructions. This processor also supports DDR4 based RAMs with maximum memory support of 64GB. The Core i9-9900KF 8-Core 3.6GHz has a maximum Thermal Power Design of 95W. It is on par with competitor processors. Among its many advanced features are Intel Optane Memory support, Intel Turbo Boost 2.0 and Virtualization technology. The Core i9-9900KF 8-Core 3.6GHz does not feature integrated graphics. This CPU is likely to offer great computational performance and will not be a bottleneck in even the most CPU-intensive AAA games in 2019.The Core i7-9700KF 8-Core 3.6GHz is a high-end CPU based on Intel's 9th Gen 14nm, Coffee Lake refresh microarchitecture.
