👁 Algebraic Multi-Grid Benchmark benchmark with settings of . DDR5-6000 was the fastest.

👁 WRF benchmark with settings of Input: conus 2.5km. DDR5-6000 was the fastest.

If going for an AMD EPYC 9005 series HPC server, that's where DDR5-6000 is definitely worthwhile. For memory bandwidth intensive HPC workloads, there is significant benefit with DDR5-6000 over DDR5-4800.

👁 ACES DGEMM benchmark with settings of Sustained Floating-Point Rate. DDR5-6000 was the fastest.

👁 LULESH benchmark with settings of . DDR5-6000 was the fastest.

👁 miniBUDE benchmark with settings of Implementation: OpenMP, Input Deck: BM2. DDR5-4800 was the fastest.

👁 LAMMPS Molecular Dynamics Simulator benchmark with settings of Model: 20k Atoms. DDR5-4800 was the fastest.

👁 miniFE benchmark with settings of Problem Size: Small. DDR5-6000 was the fastest.

👁 ASKAP benchmark with settings of Test: tConvolve MPI, Degridding. DDR5-6000 was the fastest.

👁 ASKAP benchmark with settings of Test: tConvolve MPI, Gridding. DDR5-6000 was the fastest.

👁 ASKAP benchmark with settings of Test: tConvolve MT, Gridding. DDR5-6000 was the fastest.

For most HPC workloads there is a measurable benefit from DDR5-6000 over DDR5-4800 for this AMD EPYC 9755 1P server testing.

👁 CloverLeaf benchmark with settings of Input: clover_bm64_short. DDR5-6000 was the fastest.

👁 CloverLeaf benchmark with settings of Input: clover_bm16. DDR5-6000 was the fastest.
