Relative throughput

Lower Fluent runtime means a longer animated bar.

All benchmark entries use the same Fluent case. Each DRAM channel is populated with DDR4/DDR5 RAM.

CPU Benchmark for CFD

Benchmark Fluent performance comparison from the same LES case with 15,000,000 mesh cells and 50 iterations.

Lower Fluent runtime means a longer animated bar.

All benchmark entries use the same Fluent case. Each DRAM channel is populated with DDR4/DDR5 RAM.
