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 AMD EPYC 9654 has a larger number of cores, the turbo frequency of AMD EPYC 9654 is bigger, that the PDT of AMD EPYC 7742 is lower. The AMD EPYC 9654 was started more recently.

Performance comparison with the benchmarks:

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

PassMark - CPU Mark & single thread
AMD EPYC 9654 2,881
AMD EPYC 7742 2,163

In single core, the difference is 33%. In multi-core, the difference in terms of gap is 78%.

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:

Geekbench 5 - Multi-core & single core score - Windows
AMD EPYC 9654 1,085
AMD EPYC 7742 975

In single core, the difference is 11%. In multi-core, the difference in terms of gap is 44%.

On Linux:

Geekbench 5 - Multi-core & single core score - Linux
AMD EPYC 9654 1,530
AMD EPYC 7742 1,004

In single core, the difference is 52%. In multi-core, the difference in terms of gap is 86%.

Geekbench 5 is a software for measuring the performance of a computer system, for fixed devices, mobile devices, servers. This platform makes it possible to better compare the power of the CPU, the computing power and to compare it with similar or totally different systems. Geekbench 5 includes new workloads that represent work tasks and applications that we can find in reality.
