👁 QMCPACK benchmark with settings of Input: Li2_STO_ae. EPYC 4585PX was the fastest.

👁 QMCPACK benchmark with settings of Input: H4_ae. EPYC 4585PX was the fastest.

👁 RELION benchmark with settings of Test: Basic, Device: CPU. EPYC 4585PX @ DDR5-4800 was the fastest.

👁 NAMD benchmark with settings of Input: ATPase with 327,506 Atoms. EPYC 4585PX was the fastest.

👁 NAMD benchmark with settings of Input: STMV with 1,066,628 Atoms. EPYC 4585PX was the fastest.

👁 GROMACS benchmark with settings of Implementation: MPI CPU, Input: water_GMX50_bare. EPYC 4585PX was the fastest.

For some of the HPC workloads deploying to these lower-cost EPYC processors, the DDR5-5600 memory can provide some obvious benefit too over DDR5-4800.

👁 OpenRadioss benchmark with settings of Model: Bird Strike on Windshield. EPYC 4585PX was the fastest.

👁 OpenRadioss benchmark with settings of Model: Cell Phone Drop Test. EPYC 4585PX was the fastest.

👁 OpenRadioss benchmark with settings of Model: INIVOL and Fluid Structure Interaction Drop Container. EPYC 4585PX was the fastest.

👁 ACES DGEMM benchmark with settings of Sustained Floating-Point Rate. EPYC 4585PX was the fastest.

Just how much DDR5-5600 benefits over DDR5-4800 can vary by the HPC workload, so hopefully all of these data points are beneficial for helping in any buying decisions.
