👁 High Performance Conjugate Gradient benchmark with settings of X Y Z: 104 104 104, RT: 60. 2 x 16GB DDR5-8000 Corsair CMH32GX5M2X8000C36 was the fastest.

👁 NAS Parallel Benchmarks benchmark with settings of Test / Class: BT.C. 2 x 16GB DDR5-8000 Corsair CMH32GX5M2X8000C36 was the fastest.

👁 NAS Parallel Benchmarks benchmark with settings of Test / Class: CG.C. 2 x 16GB DDR5-8000 Corsair CMH32GX5M2X8000C36 was the fastest.

👁 NAS Parallel Benchmarks benchmark with settings of Test / Class: FT.C. 2 x 16GB DDR5-8000 Corsair CMH32GX5M2X8000C36 was the fastest.

👁 NAS Parallel Benchmarks benchmark with settings of Test / Class: IS.D. 2 x 16GB DDR5-8000 Corsair CMH32GX5M2X8000C36 was the fastest.

For those planning to use an Intel Arrow Lake desktop for any HPC-type workloads where memory bandwidth can be critical, the DDR5-8000 memory was proving definitely a worthwhile investment.

👁 NAS Parallel Benchmarks benchmark with settings of Test / Class: LU.C. 2 x 16GB DDR5-8000 Corsair CMH32GX5M2X8000C36 was the fastest.

👁 NAS Parallel Benchmarks benchmark with settings of Test / Class: SP.C. 2 x 16GB DDR5-8000 Corsair CMH32GX5M2X8000C36 was the fastest.

The DDR5-6400 Corsair CMK64GX5M2B6400C32 memory kit was performing very well too and often performing not far behind the DDR5-8000 DIMMs. The CMK64GX5M2B6400C32 DIMMs are 32GB rather than 16GB or 24GB with the other kits tested. But it is an interesting comparison point as the 2 x 16GB DDR5-8000 memory modules tested retail for around $190 USD while the 2 x 32GB DDR5-6400 memory modules tested retail for about $205 USD. So they are very close from a cost perspective for those trying to evaluate if going for higher memory capacity or higher speed memory is more advantageous.

👁 CP2K Molecular Dynamics benchmark with settings of Input: H20-64. 2 x 16GB DDR5-8000 Corsair CMH32GX5M2X8000C36 was the fastest.

👁 CP2K Molecular Dynamics benchmark with settings of Input: H20-256. 2 x 16GB DDR5-8000 Corsair CMH32GX5M2X8000C36 was the fastest.

The Micron DDR5-6400 CUDIMMs with their CAS 52 latency rating are hardly interesting compared to the Corsair DDR5-6400 DIMMs with a CAS latency of 34.
