AMD has announced its new EPYC 4005 Series processors, its second generation of enterprise CPUs designed for Socket AM5 – the same socket shared with its consumer-facing Ryzen 9000 processors. As a matter of fact, the lineup effectively mirrors the consumer lineup in core counts, though as EPYCs they do get some extra security features for enterprise environments.
AMD EPYC 4005 Series
The EPYC 4005 Series includes multiple models based on the Zen 5 architecture, offering between six and sixteen cores, support for DDR5 memory, and PCIe 5.0 connectivity (identical to Ryzen 9000 counterparts). From the top, you have the EPYC 4585PX as the enterprise counterpart of Ryzen 9 9950X3D, though the majority of the lineup caps the power limit to just 65W.
| Model | Cores / Threads | L3 Cache | Default TDP | Base Clock | Boost Clock | Price (1K units) |
| 4585PX | 16C / 32T | 128MB (3D V-Cache) | 170W | 4.3 GHz | 5.7 GHz | $699 |
| 4565P | 16C / 32T | 64MB | 170W | 4.3 GHz | 5.7 GHz | $589 |
| 4545P | 16C / 32T | 64MB | 65W | 3.0 GHz | 5.4 GHz | $549 |
| 4465P | 12C / 24T | 64MB | 65W | 3.4 GHz | 5.4 GHz | $399 |
| 4345P | 8C / 16T | 32MB | 65W | 3.8 GHz | 5.5 GHz | $329 |
| 4245P | 6C / 12T | 32MB | 65W | 3.9 GHz | 5.4 GHz | $239 |
Per AMD’s first party benchmarks, the company claims its flagship EPYC 4585PX is 47% to 124% faster than the 8-core Intel Xeon 6369P, based on the Raptor Lake architecture (the same as Intel Core 13th/14th Gen); for Phoronix benchmarks, it claims the EPYC 4565P is 83% faster than the same Xeon chip. All models are now available via server vendors including Altos, ASRock Rack, Gigabyte, Lenovo, MSI, OVHcloud, and Supermicro.
