Intel Open Image Denoise benchmark with settings of Run: RT.ldr_alb_nrm.3840x2160, Device: CPU-Only. Xeon 6980P 2P - MRDIMM-8800 was the fastest.
Intel Open Image Denoise benchmark with settings of Run: RTLightmap.hdr.4096x4096, Device: CPU-Only. Xeon 6980P 2P - MRDIMM-8800 was the fastest.

There were also benefits to MRDIMMs in other creator workloads like Open Image Denoise.

Blender benchmark with settings of Blend File: Barbershop, Compute: CPU-Only. Xeon 6980P 2P - MRDIMM-8800 was the fastest.

For renderer workloads like Blender there was little benefit to MRDIMMs over DDR5-6400 with the Xeon 6980P.

Liquid-DSP benchmark with settings of Threads: 1, Buffer Length: 256, Filter Length: 512. Xeon 6980P 2P - MRDIMM-8800 was the fastest.
Liquid-DSP benchmark with settings of Threads: 256, Buffer Length: 256, Filter Length: 512. Xeon 6980P 2P - MRDIMM-8800 was the fastest.

In some other areas like Liquid-DSP digital signal processing the MRDIMM 8800 performance was providing a beneficial bump over DDR5-6400 memory.

srsRAN Project benchmark with settings of Test: PDSCH Processor Benchmark, Throughput Total. Xeon 6980P 2P - MRDIMM-8800 was the fastest.

MRDIMMs were also helping Granite Rapids within the srsRAN 5G RAN software performance.

OpenVINO benchmark with settings of Model: Vehicle Detection FP16-INT8, Device: CPU. Xeon 6980P 2P - MRDIMM-8800 was the fastest.
OpenVINO benchmark with settings of Model: Road Segmentation ADAS FP16-INT8, Device: CPU. Xeon 6980P 2P - MRDIMM-8800 was the fastest.

Within some of the OpenVINO AI toolkit benchmarks were also some performance gains when running with MRDIMMs.
