AMD introduces Epyc 4005. This series includes six new Zen 5-based server chips, developed specifically for smaller enterprises with more modest budgets.
AMD expands its range of server processors with Epyc 4005. With these server chips, AMD aims to appeal primarily to smaller enterprises looking for their own infrastructure.
Despite the significantly different type number, Epyc 4005 is a variant of Epyc 9005. The chips are based on the Zen 5 architecture, which also powers the current Ryzen portfolio. However, in its previously launched server portfolio, AMD focuses on cloud native workloads with the more efficient Zen 5c cores, enabling up to 192 cores on a single chip. AMD Epyc 4005 has a simpler architecture, with classic Zen 5 cores.
6 Newcomers
AMD introduces six chips in the family, with the Epyc 4585PX being the top model. This chip has sixteen cores, good for 32 threads. AMD advertises a base clock speed of 4.3 GHz with a turbo up to 5.7. The chip comes with a generous 128 MB L3 cache and will cost $699. The full portfolio looks as follows:
| CPU | Cores / Threads | L3-Cache (MB) | TDP (W) | Base Clock (GHz) | Boost (GHz) | Price |
| 4565P | 16 / 32 | 64 | 170 | 4.3 | 5.7 | $ 589 |
| 4545P | 16 / 32 | 64 | 65 | 3.0 | 5.4 | $ 549 |
| 4465P | 12 / 24 | 64 | 65 | 3.4 | 5.4 | $ 399 |
| 4345P | 8 / 16 | 32 | 65 | 3.8 | 5.5 | $ 329 |
| 4245P | 6 / 12 | 32 | 65 | 3.9 | 5.4 | $ 239 |
| 4585PX | 16 / 32 | 128 | 170 | 4.3 | 5.7 | $ 699 |
Efficiency should be a key attraction of these processors, as well as the price-performance ratio. All chips support DDR5 memory and PCIe 5.0 connections. AMD points out that these chips use the same AM5 socket as predecessor AMD Epyc 4004. According to their own benchmarks, the chips are up to 83 percent faster than equivalents from the Intel Xeon range.
The processor manufacturer expects a multitude of server products from manufacturers in the market. Among others, Lenovo has already indicated that systems are planned.
