Maxon Cinebench R15
CINEBENCH R15 is a cross-platform testing suite that measures hardware performance and is the de facto standard benchmarking tool for leading companies and trade journals for conducting real-world hardware performance tests. With the new Release 15, systems with up to 256 threads can be tested.
CINEBENCH is available for both Windows and OS X and is used by almost all hardware manufacturers and trade journals for comparing CPUs and graphics cards. For this test, we used the Armari Magnetar V25R-RA750G2, Scan 3XS GW-HTX35, Armari Magnetar S16T-RW850G2 and S18X-RD850G2, and Armari Magnetar S32-RD1000G2 for comparison.
Although the EPYC 7551P has the same number of cores as the Threadripper 2990WX in the Armari Magnetar S32T-RD1000G2, they are running at 2.55GHz with the EPYC, and at 4GHz with the (overclocked) 2990WX. This has a clear effect on performance, with a 32 per cent deficit compared to the 2990WX.
In fact, the EPYC is only 17 per cent faster than the 16-core Threadripper 1950X in the Armari Magnetar S16T-RW850G2, and five per cent faster than the 18-core Intel Core i9-7980XE.
The Open GL result is even more disappointing, because this test is very clock-speed sensitive. Because the EPYC 7551P has a maximum single-core frequency of just 3GHz, this holds back the AMD Radeon Pro WX 9100 graphics considerably.
