- The reference points show the new EPYC 4005 series of AMD exceed the EPYC 7601 Eight older channels with only two DIMMS
- The performance improvements per watt place the AMD chip 4005 in a new server efficiency league
- Grade demonstrates that the newest design exceeds the oldest bulk: less memory, lower power, even more performance
In an eight -year jump, the new EPYC 4585PX processor of the “grade” EPYC 4005 series has shown performance improvements that almost tripled the ORIGINAL IGD SERIOR OUTPUT OF SERIOR OF AMD, EPYC 7601.
Interestingly, the EPYC 4585PX processor is not part of the EPYC 9005 high -end family, but a low and efficient alternative in power.
According to Phoronix, more than 200 reference points were executed in Ubuntu 25.04 through various workloads, server tasks, HPC, command sequences, media coding and compilation.
The reference points highlight a dramatic efficiency leap
On average, the EPYC 4585PX delivered the performance of the original 7601, despite fewer memory channels and a more compact configuration.
When adjusting to power, improvement seems even more surprising: depending on the performance by watt, the newest chip is 2.85 times more efficient, thanks to the most refined architecture and better design efficiency.
These results are likely to interest the best hardware enthusiasts, and ask questions about how old the oldest business systems have remained.
It also puts the lower cost of AMD in the dispute with more expensive processors typically used by top -level web accommodation suppliers.
However, not everything is a clean victory. While the use of complete system of the complete system improved significantly, 225W for the newest platform compared to 238W for the oldest Naples server, the measures at the CPU level were less decisive.
The average CPU consumption was 153 W for the EPYC 4585px and 141W for the previous 7601, with maximum values of 204W and 195W, respectively.
These figures suggest that although the system as a whole has become more efficient, the processor has only reduced the use of energy so dramatically.
For those looking for green infrastructure, especially small businesses or Soho configurations, the lowest inactive raffle may be more relevant than full load comparisons.
With a modern supermicro platform with only two DDR5 DIMM, the EPYC 4585PX system still managed to overcome the performance of the eight channels of the EPYC 7601 in most workloads.
That suggests that memory bandwidth is no longer the only performance determinant.
With support for newer chips sets and more efficient memory, the “grade” system seems to offer real head space for input level infrastructure implementations, especially for NAS compilations where energy efficiency and thermal limits matter.
The data show that the EPYC 4005 low cost of AMD can now overcome the former flagships without breaking the bank or the energy budget.
The next comparison with EPYC 9005 chips promises even greater profits, although the food to carry for now is that it no longer needs a premium part to obtain premium performance.
