Core i9-12900K vs Ryzen 9 7940HX benchmarks

Our benchmark analysis concludes that the Ryzen 9 7940HX performs better than the Core i9-12900K. Despite this, the Core i9-12900K has the advantage in our gaming benchmark.

Info from our database shows that they both have the same core count but the Ryzen 9 7940HX has more threads. With our hardware info, we find that the Core i9-12900K has a slightly higher clock speed than the Ryzen 9 7940HX. In addition, both chips have the same turbo speed. The Ryzen 9 7940HX outputs less heat than Core i9-12900K thanks to a significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

The more cores a CPU has, the better the overall performance will be in parallel workloads such as multitasking. Many CPUs have more threads than cores, this means that each physical core is split into multiple logical cores, making them more efficient. Indeed, the Core i9-12900K has more threads than cores. Each physical core is split into multiple threads.
