Overview
SummaryThe AMD Opteron 4122 is a server processor with 4 cores and 4 threads. It launched in Jun 2010. A 6-MB L3 cache backs the cores (2.1 MB per core). It uses the C32 socket. Rated TDP is 95 W.
Performance
5 metricsThe AMD Opteron 4122 scores 1,913 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 1,841 for engineering performance. Its multi-core throughput works out to 478 per core, 478 per thread and 20 per watt. 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 4122.
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 4122 has 4 physical cores and runs 4 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.
Architecture & Generation
4 specsThe AMD Opteron 4122 is a server processor and belongs to the AMD Opteron family. It launched in Jun 2010.
Cache
6 specsThe AMD Opteron 4122 has 512 KB of L1 cache, 2 MB of L2 cache and 6 MB of L3 cache. That adds up to about 8.5 MB of cache, or 2.13 MB per core. Each core has 512 KB of private L2 cache.
Cache Hierarchy
3 levelsThe AMD Opteron 4122 has a 3-level cache hierarchy: L1 at 512 KB, L2 at 2 MB and L3 at 6 MB. L3 is the largest level and makes up about 71% of the cache listed here.
