Description
The AMD EPYC 7451 is a 24-core, 48-thread first-generation server processor built on Zen, part of AMD's original EPYC Naples lineup, running a 2.3 GHz base clock that boosts to 3.2 GHz within a 180 Watt TDP.
As part of AMD's original 2017 EPYC server launch, this chip helped establish AMD's genuine return to enterprise server competitiveness before the later Zen 2-based Rome generation brought meaningful architectural improvements.
Platform
This server-class chip requires the specialized LGA 4094 (SP3) server socket, typically deployed in dual-socket configurations for data center-scale aggregate core counts.
How Is the EPYC 7451 in Terms of Performance
With 24 cores and 48 threads, this chip is built for server and data center workloads, representing AMD's original first-generation EPYC architecture before the later Zen 2-based Rome generation brought meaningful improvements.
Benchmarks
As a first-generation Zen EPYC server chip, this processor's per-core performance reflects the more modest ceiling of the original architecture relative to later Rome-generation EPYC chips, though its genuine 24-core capability remains solid for its era.

Expert Review
Rated by the Consumercarts editorial team, not by users
Best for
- Data center deployments specifically running AMD's original first-generation EPYC platform
Not for
- Buyers with access to later Rome-generation EPYC chips — those offer meaningfully better per-core performance
