In a leap of eight years, AMDThe new EPYC 4585PX processor from the EPYC 4005 “Grado” series has shown performance improvements that the output of AMD’s original flagship server chip, the EPYC 7601, almost triple.
Interestingly, the EPYC 4585PX processor is not part of the high-end EPYC 9005 family, but rather a cheaper, powerful alternative.
According to PhoronixMore than 200 benchmarks were performed on Ubuntu 25.04 for different workloads, server tasks, HPC, scripting, media coding and compilation.
Benchmarks emphasize a dramatic efficiency jump
On average, the EPYC 4585px delivered 2.69 times the performance of the original 7601, despite fewer memory channels and a more compact setup.
When adapted for electricity, the improvement looks even more striking: based on performance per watt, the newer chip is 2.85x more efficient, thanks to more refined architecture and improved design efficiency.
These results will probably be enthusiasts of the Best Server Hardware, and they raise questions about how far older business systems have been left behind.
It also brings AMD’s cheaper chips in violation of more expensive processors that are usually used by top class web hosting providers.
However, not everything is a clean victory. While the wall consumption of the entire system was considerably improved – 225 W for the newer platform compared to 238W for the older Naples server – the measurements at CPU level were less decisive.
The average CPU consumption was 153W for the EPYC 4585px and 141W for the older 7601, with peak values of 204W and 195W respectively.
These figures suggest that although the system as a whole has become more efficient, only the processor has not lowered energy consumption so dramatically.
For those who are looking for green infrastructure, in particular operators of small businesses or SOHO setups, the lower inactive draw can be more relevant than comparisons with full load.
Running on a modern supermicro platform with only two DDR5 DIMMs, the EPYC 4585PX system still succeeded in beating the eight-channel memory performance of the EPYC 7601 in most workloads.
This suggests that the memory band width is no longer the only performance base.
With support for newer chipsets and more efficient memory, the “Grado” system seems to offer a real headroom for entry -in infrastructure implementations, in particular for NAS Builds where power efficiency and thermal limits matter.
The data shows that the cheap EPYC 4005 chips from AMD may now perform better than former flagships without breaking the bank or the energy budget.
The upcoming comparison with EPYC 9005 chips promises even greater profit, although the collection meals are for the time being that you no longer need a premium part to get premium performance.
