Ryzen 9 4900H vs Core i9-9900 benchmarks
Our benchmark analysis concludes that the Core i9-9900 performs better than the Ryzen 9 4900H. Furthermore, our gaming benchmark shows that it also outperforms the Ryzen 9 4900H in all gaming tests too.
Info from our database shows that they both have the same core count and the same number of threads. With our hardware info, we find that the Ryzen 9 4900H has a slightly higher clock speed than the Core i9-9900. Despite this, the Core i9-9900 has a slightly higher turbo speed. A Ryzen 9 4900H CPU outputs less heat than a Core i9-9900 CPU because of its significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. The cache sizes of these CPUs are different. Indeed, the Ryzen 9 4900H has significantly more L2 cache than the Core i9-9900. Despite this, the Core i9-9900 has significantly more L3 cache compared to the Ryzen 9 4900H.
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 9 4900H has more threads than cores. Each physical core is split into multiple threads.
