Intel® Atom™ D2550
The Intel Atom D2550 is a desktop processor released on January 1, 2012, built on the Cedarview architecture using a 32 nm process. It has 2 cores and 4 threads, a base clock of 1.86 GHz, 1 MB of L3 cache, a 10 W TDP and the FCBGA559 socket.
Overview
SummaryThe Intel Atom D2550 is a desktop processor with 2 cores and 4 threads, built on the Cedarview architecture. It launched in Jan 2012. A 1-MB L3 cache backs the cores (1.0 MB per core). It addresses DDR3 memory up to 4 GB across 1 channels. It uses the FCBGA559 socket. Rated TDP is 10 W.
Performance
12 metricsThe Intel Atom D2550 scores 325 in single-core performance and 410 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 365 for overall performance, 722 for productivity performance, 811 for creator performance, 382 for engineering performance and 1,078 for gaming performance. Its multi-core throughput works out to 205 per core, 103 per thread and 41 per watt. Its computed efficiency index is 115. Its performance index is 5, so its overall performance is 95% 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 Intel Atom D2550 scores 1,610 in integer math, 678 in floating-point math, 11,531 in compression, 111 in cryptography, 64 in physics simulation, 161 in vector SIMD, 2 in the prime sieve and 1,652 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 97% below in integer math, 99% below in floating-point math, 95% below in compression, 99% below in cryptography, 94% below in physics simulation, 99% below in vector SIMD, 97% below in the prime sieve and 93% 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.
