We can better compare what are the technical differences between the two processors.

Suggested PSU: We assume that we have An ATX computer case, a high end graphics card, 16GB RAM, a 512GB SSD, a 1TB HDD hard drive, a Blu-Ray drive. We will have to rely on a more powerful power supply if we want to have several graphics cards, several monitors, more memory, etc.

Price: For technical reasons, we cannot currently display a price less than 24 hours, or a real-time price. This is why we prefer for the moment not to show a price. You should refer to the respective online stores for the latest price, as well as availability.

The processor Intel Core i9-7920X has a larger number of cores, the maximum frequency of Intel Core i7-11700F is greater, that the PDT of Intel Core i7-11700F is lower. The Intel Core i7-11700F was designed earlier.

Performances :


Performance comparison between the two processors, for this we consider the results generated on benchmark software such as Geekbench 4.


CPU-Z - Multi-thread & single thread score
Intel Core i9-7920X#ad 478
6,387
Intel Core i7-11700F#ad 641
6,051


In single core, the difference is 34%. In multi-core, the difference in terms of gap is 6%.


CPU-Z is a system information software that provides the name of the processor, its model number, the codename, the cache levels, the package, the process. It can also gives data about the mainboard, the memory. It makes real time measurement, with finally a benchmark for the single thread, as well as for the multi thread.


PassMark - CPU Mark & single thread
Intel Core i9-7920X#ad 2,510
23,450
Intel Core i7-11700F#ad 3,389
21,014


In single core, the difference is 35%. In multi-core, the difference in terms of gap is 12%.


PassMark is a benchmarking software that performs several performance tests including prime numbers, integers, floating point, compression, physics, extended instructions, encoding, sorting. The higher the score is, the higher is the device capacity.





On Windows 64-bit:

Geekbench 4 - Multi-core & single core score - Windows 64-bit
Intel Core i7-11700F#ad 7,353
