Where Each One Wins

The AMD EPYC 7513 dominates the compute-heavy and parallel workloads. Its 32 cores and 64 threads provide a substantial advantage in multi-threaded rendering, as shown by Cinebench R23 multicore: 50,431 versus 44,277, a 13.9% lead. The same 13.9% margin appears across Cinebench R15, R20, and R23 multicore tests, indicating a consistent scaling advantage. In PassMark multithread, the AMD chip scores 59,331 versus 52,091, again 13.9% ahead.

The AMD EPYC 7513 also wins decisively in integer-heavy and encryption workloads. PassMark integer math shows 272,145 for the AMD part versus 219,924 for the Intel part, a 23.7% margin. Data encryption is a major gap: the AMD chip scores 63,628 versus 39,295, a 61.9% advantage. The physics test is the most lopsided, with the AMD EPYC 7513 at 5,118 versus 2,222 for the Intel Xeon, a 130.3% difference.

The Intel Xeon w7-2575X wins in floating-point math and extended instruction workloads. PassMark floating point math shows 171,427 for the Intel part versus 151,713 for the AMD part, an 11.5% edge. Extended instructions go to the Intel chip at 62,498 versus 56,451, a 9.7% margin. The Intel part also wins the PassMark single-thread test by 24.9%, but this does not translate to Cinebench single-core, where AMD leads.

For workloads that rely on single-thread responsiveness and high clock speeds, the Intel Xeon w7-2575X with its 4.80 GHz boost clock is the better choice. For dense multi-threaded tasks, data encryption, and physics simulation, the AMD EPYC 7513's core count and cache capacity make it the stronger option.
