Core i9-12900H vs Ryzen 7 5800X3D specs and performance
According to the hardwareDB Benchmark tool, the Core i9-12900H is faster than the Ryzen 7 5800X3D. Furthermore, our gaming benchmark shows that it also outperforms the Ryzen 7 5800X3D in all gaming tests too.
When comparing core counts for these CPUs, we notice that the Core i9-12900H has significantly more cores with 14 cores compared to the Ryzen 7 5800X3D that has 8 cores. It also has more threads than the Ryzen 7 5800X3D. Our comparison shows that the Ryzen 7 5800X3D has a slightly higher clock speed compared to the Core i9-12900H. Despite this, the Core i9-12900H has a slightly higher turbo speed. A Core i9-12900H CPU outputs less heat than a Ryzen 7 5800X3D 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 i9-12900H has more threads than cores. Each physical core is split into multiple threads.
