- Benchmarks present AMD’s new EPYC 4005 collection outperforming older eight-channel EPYC 7601 reminiscence techniques with simply two DIMMs
- Efficiency-per-Watt enhancements put AMD’s 4005 chip in a brand new league of server effectivity
- Grado proves newer design beats older bulk – much less reminiscence, decrease energy, but extra efficiency
In an eight-year leap, AMD’s new EPYC 4585PX processor from the EPYC 4005 “Grado” collection has proven efficiency enhancements that almost triple the output of AMD’s authentic flagship server chip, the EPYC 7601.
Curiously, the EPYC 4585PX processor will not be a part of the high-end EPYC 9005 household however quite a lower-cost, power-efficient different.
In line with Phoronix, over 200 benchmarks have been run on Ubuntu 25.04 throughout various workloads, server duties, HPC, scripting, media encoding, and compilation.
Benchmarks spotlight a dramatic effectivity soar
On common, the EPYC 4585PX delivered 2.69 instances the efficiency of the unique 7601, regardless of fewer reminiscence channels and a extra compact setup.
When adjusted for energy, the development seems to be much more placing: on a performance-per-Watt foundation, the newer chip is 2.85x extra environment friendly, because of extra refined structure and improved design effectivity.
These outcomes are more likely to curiosity lovers of the perfect server {hardware}, and so they increase questions on how far older enterprise techniques have fallen behind.
It additionally places AMD’s lower-cost chips in rivalry with costlier processors usually utilized by top-tier hosting suppliers.
Not every part is a clear win, nevertheless. Whereas the wall energy utilization of the complete system was considerably improved – 225W for the newer platform in comparison with 238W for the older Naples server – the CPU-level measurements have been much less decisive.
Common CPU consumption was 153W for the EPYC 4585PX and 141W for the older 7601, with peak values of 204W and 195W, respectively.
These figures counsel that whereas the system as a complete has develop into extra environment friendly, the processor alone hasn’t reduce vitality use as dramatically.
For these looking for inexperienced infrastructure, particularly small enterprise operators or SOHO setups, the decrease idle draw could also be extra related than full-load comparisons.
Working on a contemporary Supermicro platform with simply two DDR5 DIMMs, the EPYC 4585PX system nonetheless managed to beat the eight-channel reminiscence efficiency of the EPYC 7601 in most workloads.
That means reminiscence bandwidth isn’t the one efficiency determinant anymore.
With assist for newer chipsets and extra environment friendly reminiscence, the “Grado” system seems to supply actual headroom for entry-level infrastructure deployments, particularly for NAS builds the place energy effectivity and thermal limits matter.
The info reveals AMD’s low-cost EPYC 4005 chips could now outperform former flagships with out breaking the financial institution or the ability finances.
The upcoming comparability with EPYC 9005 chips guarantees even larger positive factors, though the takeaway for now could be that you simply not want a premium half to get premium efficiency.
