Ryzen 7 3800X vs Core i7-9700KF comparison

Our benchmark analysis concludes that the Ryzen 7 3800X performs better than the Core i7-9700KF. Despite this, the Core i7-9700KF has the advantage in our gaming benchmark.

When comparing these CPUs we notice that they have the same number of cores but the Ryzen 7 3800X has more threads. These CPUs have different clock speeds. Indeed, the Ryzen 7 3800X has a slightly higher clock speed compared to the Core i7-9700KF. Despite this, the Core i7-9700KF has a slightly higher turbo speed. The Core i7-9700KF outputs less heat than Ryzen 7 3800X thanks to a slightly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. In terms of cache, the Ryzen 7 3800X has significantly more L2 cache when compared to the Core i7-9700KF. The Ryzen 7 3800X also has significantly more L3 cache.

Most CPUs have more threads than cores. This technology, colloquially called hyperthreading, improves performance by splitting a core into multiple virtual ones. This provides more efficient utilisation of a core. Indeed, the Ryzen 7 3800X has more threads than cores. Each physical core is split into multiple threads.
