AMD announced the performance comparison result of the 3rd generation EPYC top model ' EPYC 7763 ' and the server CPU ' Xeon Gold 6258R' released by Intel in 2020 in the announcement of the 3rd generation EPYC. The floating point computing power of 'EPYC 7763' is claimed to be 106% higher than that of 'Xeon Gold 6258 R'.



Furthermore, the virtual machine effective performance of 'EPYC 7763' is 117% higher than that of 'Xeon Gold 6258 R'.



The specifications of the 1st generation EPYC '

EPYC 7601 ', the 2nd generation EPYC ' EPYC 7742 ', the 3rd generation EPYC 'EPYC 7763', and the Intel 'Xeon Gold 6258 R' are like this.

AnandTech, a technical media, measures the multi-thread performance of 'EPYC 7763', 'EPYC 7742', ' Xeon Platinum 8280 ' and ' Ampere Altra Q80-30 ' using the benchmark software 'SPEC'. As a result, 'EPYC 7763' scored more than twice as much as 'Xeon Platinum 8280' in most tests.



The benchmark score for single thread performance looks like this. The 2nd generation EPYC 'EPYC 7742' is lower than the 'Xeon Platinum 8280' in single thread performance, but the newly introduced 3rd generation EPYC 'EPYC 7763' is comparable in single thread performance to the 'Xeon Platinum 8280'. You can confirm that.



Furthermore, when comparing the compilation speed using the compiler 'LLVM ', it can be confirmed that the compilation speed of the machine equipped with one 'EPYC 7763' is faster than that of the machine equipped with two 'Xeon Platinum 8280'.



AMD's Forest Noroddo senior vice president of AnandTech interview against, 'third-generation EPYC is available mounted on the same motherboard as the second generation EPYC. In addition, the software also has maintained a high degree of compatibility. Therefore, users Can make the transition from 2nd generation EPYC to 3rd generation EPYC smooth. '
