Description
Launched mid-2019, the AMD EPYC 7662 is a 64-core, 128-thread server processor built on Zen 2 as part of the EPYC Rome lineup, running a 2.0 GHz base clock that boosts to 3.3 GHz within a 225 Watt TDP.
Sharing an identical core count and near-matching clocks with the flagship 7742, this chip sits at a similar performance tier within AMD's broad Rome server lineup, offering data centers another 64-core configuration option.
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 7662 in Terms of Performance
With 64 cores and 128 threads at the same 225W TDP as the flagship 7742, this chip delivers very similar real-world server performance, giving data center buyers another configuration option within AMD's broad Rome lineup.
Benchmarks
Cinebench R20 multi-core scores of 18,198 and single-core scores of 388 sit close to the flagship EPYC 7742's figures, confirming this chip delivers very similar genuine server-tier throughput within AMD's Rome lineup.
