Overview
SummaryThe Intel Xeon L5530 is a server processor with 4 cores and 8 threads, built on the Nehalem architecture. It launched in Aug 2009. Clocks run from 2.4 GHz base to 2.66 GHz boost. A 8-MB L3 cache backs the cores (2.3 MB per core). It supports DDR3 memory. It uses the FCLGA1366 socket. Rated TDP is 60 W.
Performance
12 metricsThe Intel Xeon L5530 scores 1,169 in single-core performance and 2,522 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 1,717 for overall performance, 3,276 for productivity performance, 3,491 for creator performance, 2,427 for engineering performance and 4,138 for gaming performance. Its multi-core throughput works out to 631 per core, 315 per thread and 42 per watt. Its computed efficiency index is 222. Its performance index is 21, so its overall performance is 79% 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 Intel Xeon L5530.
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.
