AMD® Opteron™ 4274 HE

The AMD Opteron 4274 HE is a server processor with 8 cores and 8 threads. It launched in Nov 2011. Clocks run from 2.5 GHz base to 2.8 GHz boost. A 8-MB L3 cache backs the cores (2.0 MB per core). It uses the C32 socket. Rated TDP is 65 W.

The AMD Opteron 4274 HE scores 1,060 in single-core performance and 5,776 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 2,474 for overall performance, 5,238 for productivity performance, 5,085 for creator performance, 5,920 for engineering performance and 4,624 for gaming performance. Its multi-core throughput works out to 722 per core, 722 per thread and 89 per watt. Its computed efficiency index is 307. Its performance index is 31, so its overall performance is 69% below the Intel Core i5-12400 (index 100). Each bar shows the score as a share of a reference ceiling, which is the larger of the 99th-percentile score across the Feex CPU database and a fixed baseline.

Workload sub-scores (integer math, floating point, compression, encryption, physics, SIMD, prime sieve and sorting) are not recorded for the AMD Opteron 4274 HE.

The AMD Opteron 4274 HE has 8 physical cores and runs 8 logical threads. It does not use a hybrid performance and efficiency core layout. It does not support simultaneous multithreading, so its thread count equals its core count. It runs at a base clock of 2.50 GHz and boosts up to 2.80 GHz.

The AMD Opteron 4274 HE is a server processor and belongs to the AMD Opteron family. It launched in Nov 2011.

The AMD Opteron 4274 HE has 8 MB of L2 cache and 8 MB of L3 cache. That adds up to about 16.0 MB of cache, or 2.00 MB per core. Feex has no recorded L1 cache size for this processor.

The AMD Opteron 4274 HE has a 2-level cache hierarchy: L2 at 8 MB and L3 at 8 MB. L2 is the largest level and makes up about 50% of the cache listed here.

The AMD Opteron 4274 HE uses the C32 socket.

The AMD Opteron 4274 HE has a rated TDP of 65 W.
