Core i9-7900X vs Core i9-9820X specs and performance

Our benchmark analysis concludes that the Core i9-7900X performs better than the Core i9-9820X. Despite this, the Core i9-9820X has the advantage in our gaming benchmark.

Our spec comparison shows that they have an identical amount of cores and the same number of threads. According to our data, the Core i9-7900X and Core i9-9820X have the same clock speed. Despite this, the Core i9-7900X has a slightly higher turbo speed. A Core i9-7900X CPU outputs less heat than a Core i9-9820X 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.
