Intel® Atom™ N550

The Intel Atom N550 is a laptop processor with 2 cores and 4 threads. It launched in Aug 2010. It supports DDR2, DDR3 memory. It uses the FCBGA559 socket. Rated TDP is 8.5 W.

The Intel Atom N550 scores 239 in single-core performance and 304 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 270 for overall performance, 532 for productivity performance, 597 for creator performance, 283 for engineering performance and 793 for gaming performance. Its multi-core throughput works out to 152 per core, 76 per thread and 36 per watt. Its computed efficiency index is 93. Its performance index is 3, so its overall performance is 97% 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.

Scores 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 N550 scores 1,161 in integer math, 524 in floating-point math, 8,507 in compression, 88 in cryptography, 50 in physics simulation, 115 in vector SIMD, 2 in the prime sieve and 1,099 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 98% below in integer math, 99% below in floating-point math, 96% below in compression, 99% below in cryptography, 95% below in physics simulation, 99% below in vector SIMD, 97% below in the prime sieve and 95% 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.

The Intel Atom N550 has 2 physical cores and runs 4 logical threads. It does not use a hybrid performance and efficiency core layout. It runs 2 threads per core. It runs at a base clock of 1.50 GHz.

The Intel Atom N550 is a laptop processor and belongs to the Intel Atom family. It launched in Aug 2010.

The Intel Atom N550 has 56 KB of L1 cache and 512 KB of L2 cache. That adds up to about 0.6 MB of cache, or 0.28 MB per core.

The Intel Atom N550 has a 2-level cache hierarchy: L1 at 56 KB and L2 at 512 KB. L2 is the largest level and makes up about 90% of the cache listed here.
