Even with the big performance improvement out of the EPYC 7002 line-up, the CPU temperature in this 1P 4U server configuration with the Noctua TR4-SP3 heatsink came out only marginally warmer than the Naples processors. Even with the dozens of benchmarks that spanned hours across the processors, the EPYC 7642 and EPYC 7742 processors on air cooling had not reached above 65 degrees.

Likewise, a look at the overall AC power consumption of the AsRockRack EPYCD8 1P server with the different processors throughout the many different workloads benchmarked.

Overall, the EPYC 7002 series continues delivering captivating potential that beyond the raw performance and value propositions the power efficiency is certainly a big step up over the original EPYC processor line-up.
