Overview
SummaryThe AMD Opteron 275 is a server processor with 2 cores and 2 threads. It uses the 940 socket. Rated TDP is 95 W.
Performance
12 metricsThe AMD Opteron 275 scores 445 in single-core performance and 839 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 611 for overall performance, 1,168 for productivity performance, 1,262 for creator performance, 781 for engineering performance and 1,545 for gaming performance. Its multi-core throughput works out to 420 per core, 420 per thread and 9 per watt. Its computed efficiency index is 63. Its performance index is 8, so its overall performance is 92% 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 275.
How these scores are computed
Single-core and multi-core performance are PassMark CPU Mark single-thread and multi-thread ratings. Every other figure on this page's performance section is computed by Feex from those two ratings plus core count, thread count and TDP, so it is a derived value and not a separate benchmark run.
- Overall performance is the geometric mean of the two ratings: the square root of single-core times multi-core.
- Productivity performance is 0.65 times multi-core plus 1.4 times single-core.
- Creator performance is 0.55 times multi-core plus 1.8 times single-core.
- Engineering performance is multi-core times the smaller of 1.4 and (0.9 plus cores divided by 64).
- Gaming performance is 3 times single-core plus 0.25 times multi-core.
- Performance per core, per thread and per watt divide the multi-core rating by physical cores, logical threads and TDP in watts.
- The efficiency index is the square root of single-core times multi-core, divided by the square root of TDP.
- The performance index is overall performance divided by the overall performance of the Intel Core i5-12400 (8,069), times 100.
Core Configuration
6 specsThe AMD Opteron 275 has 2 physical cores and runs 2 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 2.20 GHz.
