AMD® Opteron™ 6276

The AMD Opteron 6276 is a server processor with 16 cores and 16 threads. It launched in Nov 2011. Clocks run from 2.3 GHz base to 2.6 GHz boost. A 16-MB L3 cache backs the cores (2.0 MB per core). It uses the G34 socket. Rated TDP is 115 W.

The AMD Opteron 6276 scores 1,033 in single-core performance and 6,348 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 2,561 for overall performance, 5,572 for productivity performance, 5,351 for creator performance, 7,300 for engineering performance and 4,686 for gaming performance. Its multi-core throughput works out to 397 per core, 397 per thread and 55 per watt. Its computed efficiency index is 239. Its performance index is 32, so its overall performance is 68% 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 6276.

The AMD Opteron 6276 has 16 physical cores and runs 16 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 2.30 GHz and boosts up to 2.60 GHz.

The AMD Opteron 6276 is a server processor and belongs to the AMD Opteron family. It launched in Nov 2011.

The AMD Opteron 6276 has 16 MB of L2 cache and 16 MB of L3 cache. That adds up to about 32.0 MB of cache, or 2.00 MB per core. Feex has no recorded L1 cache size for this processor.

The AMD Opteron 6276 has a 2-level cache hierarchy: L2 at 16 MB and L3 at 16 MB. L2 is the largest level and makes up about 50% of the cache listed here.

The AMD Opteron 6276 uses the G34 socket.

The AMD Opteron 6276 has a rated TDP of 115 W.
