Core i7-7820X vs EPYC 74F3 specs and performance

In our benchmarks, the Core i7-7820X beats the EPYC 74F3 in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the EPYC 74F3 in all gaming tests too.

In terms of the number of cores of each of these CPUs, the EPYC 74F3 has slightly more cores than the Core i7-7820X. Indeed, the EPYC 74F3 has 9 cores compared to 8 cores found in the Core i7-7820X. It also has more threads than the Core i7-7820X. Our comparison shows that the Core i7-7820X has a slightly higher clock speed compared to the EPYC 74F3. A Core i7-7820X CPU outputs less heat than a EPYC 74F3 CPU because of its 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 i7-7820X has more threads than cores. Each physical core is split into multiple threads.
