Intel Core i9-7900X vs Intel Core i9-7940X

Core i9-7900X vs Core i9-7940X specs and performance

According to the hardwareDB Benchmark tool, the Core i9-7900X is faster than the Core i9-7940X. Furthermore, our gaming benchmark shows that it also outperforms the Core i9-7940X in all gaming tests too.

When comparing core counts for these CPUs, we notice that the Core i9-7940X has slightly more cores with 14 cores compared to the Core i9-7900X that has 10 cores. It also has more threads than the Core i9-7900X. These CPUs have different clock speeds. Indeed, the Core i9-7900X has a slightly higher clock speed compared to the Core i9-7940X. Furthermore, both these CPUs have identical turbo speeds. A Core i9-7900X CPU outputs less heat than a Core i9-7940X CPU because of its slightly 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 i9-7900X has more threads than cores. Each physical core is split into multiple threads.
