Intel Core i9-9900 vs Intel Core i9-7900X

Core i9-9900 vs Core i9-7900X benchmarks

According to the hardwareDB Benchmark tool, the Core i9-7900X is faster than the Core i9-9900. Furthermore, our gaming benchmark shows that it also outperforms the Core i9-9900 in all gaming tests too.

When comparing core counts for these CPUs, we notice that the Core i9-7900X has slightly more cores with 10 cores compared to the Core i9-9900 that has 8 cores. It also has more threads than the Core i9-9900. Our comparison shows that the Core i9-7900X has a slightly higher clock speed compared to the Core i9-9900. Despite this, the Core i9-9900 has a slightly higher turbo speed. A Core i9-9900 CPU outputs less heat than a Core i9-7900X CPU because of its significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

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.
