AMD EPYC 9845 Makes For A Persuasive Upgrade With Performance & Energy Efficiency
For those after high core count processors for render farms, the EPYC 9845 upgrade from EPYC 97554 was huge for being a one-generation transition and also sticking to the same DDR5-4800 server memory. The power profile / AMD P-State tuning also netted some nice efficiency improvements here too without any measurable cost to the Blender 3D render performance.
Intel's OSPRay Studio software suite is another example of a CPU rendering workload showing the excellent opportunities provided by the EPYC 9845 for better performance and efficiency on existing 400 Watt rated server platforms.
OSPRay Studio along with other Intel oneAPI rendering toolkit software like Embree is well tuned for AVX-512 and thus very much enjoying the full 512-bit data path available with the Zen 5 cores.
