16-Core AMD EPYC 4005 CPU is almost 3X faster than AMD's first server flagship - and I can't believe what a bargain that is

• Benchmarks show AMD’s new EPYC 4005 series outperforming older eight-channel EPYC 7601 memory systems with just two DIMMs
• Performance-per-Watt improvements put AMD’s 4005 chip in a new league of server efficiency
• Grado proves newer design beats older bulk - less memory, lower power, yet more performance

In an eight-year leap, AMD’s new EPYC 4585PX processor from the EPYC 4005 “Grado” series has shown performance improvements that nearly triple the output of AMD’s original flagship server chip, the EPYC 7601.

Interestingly, the EPYC 4585PX processor is not part of the high-end EPYC 9005 family but rather a lower-cost, power-efficient alternative.

According to Phoronix, over 200 benchmarks were run on Ubuntu 25.04 across varied workloads, server tasks, HPC, scripting, media encoding, and compilation.
