Overview
SummaryThe AMD Opteron 3280 is a server processor with 8 cores and 8 threads. It launched in Mar 2012. Clocks run from 2.4 GHz base to 2.7 GHz boost. A 8-MB L3 cache backs the cores (2.0 MB per core). It uses the AM3+ socket. Rated TDP is 65 W.
Performance
12 metricsThe AMD Opteron 3280 scores 1,062 in single-core performance and 3,783 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 2,004 for overall performance, 3,946 for productivity performance, 3,992 for creator performance, 3,878 for engineering performance and 4,132 for gaming performance. Its multi-core throughput works out to 473 per core, 473 per thread and 58 per watt. Its computed efficiency index is 249. Its performance index is 25, so its overall performance is 75% 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.
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.
Workload Benchmarks
8 workloadsScores for individual PassMark CPU Mark test categories. Higher is better. These are measured test scores, not computed from the single-core and multi-core ratings.
In the individual workload tests the AMD Opteron 3280 scores 13,993 in integer math, 7,041 in floating-point math, 61,894 in compression, 1,151 in cryptography, 402 in physics simulation, 1,865 in vector SIMD, 23 in the prime sieve and 8,215 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 76% below in integer math, 85% below in floating-point math, 73% below in compression, 90% below in cryptography, 63% below in physics simulation, 88% below in vector SIMD, 66% below in the prime sieve and 64% below in sorting. Each bar shows the score as a share of that workload's reference ceiling, the larger of the 99th-percentile score across CPUs with a recorded value and a fixed baseline.
Core Configuration
7 specsThe AMD Opteron 3280 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 2.40 GHz and boosts up to 2.70 GHz.
