Core i9-9900 vs Ryzen 9 6900HX specs and performance

According to the hardwareDB Benchmark tool, the Ryzen 9 6900HX is faster than the Core i9-9900. Despite this, the Core i9-9900 has the advantage in our gaming benchmark.

When comparing these CPUs we notice that they have the same number of cores and the same number of threads. These CPUs have different clock speeds. Indeed, the Ryzen 9 6900HX has a slightly higher clock speed compared to the Core i9-9900. Despite this, the Core i9-9900 has a slightly higher turbo speed. The Ryzen 9 6900HX outputs less heat than Core i9-9900 thanks to a significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. The info from our database shows that the Ryzen 9 6900HX has more L2 cache than the Core i9-9900. However, both these chips have the same amount of 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 Core i9-9900 has more threads than cores. Each physical core is split into multiple threads.
