Intel® Atom™ C2550

The Intel Atom C2550 is a server processor with 4 cores and 4 threads, built on the Avoton architecture. It launched in Jul 2013. Clocks run from 2.4 GHz base to 2.6 GHz boost. A 2-MB L3 cache backs the cores (1.1 MB per core). It addresses DDR3 memory up to 64 GB across 2 channels. The chip drops into the FCBGA1283 socket and exposes PCIe 2.0 (16 lanes). Rated TDP is 14 W. Notable platform capabilities: Extended Page Tables (EPT).

The Intel Atom C2550 scores 554 in single-core performance and 1,422 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 888 for overall performance, 1,700 for productivity performance, 1,779 for creator performance, 1,369 for engineering performance and 2,018 for gaming performance. Its multi-core throughput works out to 356 per core, 356 per thread and 102 per watt. Its computed efficiency index is 237. Its performance index is 11, so its overall performance is 89% 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 C2550 scores 7,838 in integer math, 1,736 in floating-point math, 34,200 in compression, 668 in cryptography, 172 in physics simulation, 508 in vector SIMD, 7 in the prime sieve and 4,434 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 87% below in integer math, 96% below in floating-point math, 85% below in compression, 94% below in cryptography, 84% below in physics simulation, 97% below in vector SIMD, 90% below in the prime sieve and 80% 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 C2550 has 4 physical cores and runs 4 logical threads. 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 2.60 GHz.

The Intel Atom C2550 is a server processor, belongs to the Intel Atom C family, uses the Avoton architecture, carries the codename Avoton and is manufactured on a 22 nm process. It launched in Jul 2013.

The Intel Atom C2550 has 448 KB of L1 cache, 2 MB of L2 cache and 2 MB of L3 cache. That adds up to about 4.4 MB of cache, or 1.11 MB per core.

The Intel Atom C2550 has a 3-level cache hierarchy: L1 at 448 KB, L2 at 2 MB and L3 at 2 MB. L2 is the largest level and makes up about 45% of the cache listed here.

The Intel Atom C2550 supports DDR3 memory, addresses up to 64 GB of memory and uses 2 memory channels. It does not support DDR5, DDR4 and LPDDR memory.

The Intel Atom C2550 uses the FCBGA1283 socket, supports PCI Express 2.0 and provides up to 16 PCIe lanes.

The Intel Atom C2550 has a rated TDP of 14 W.
