Intel® Atom™ x5-Z8550

The Intel Atom x5-Z8550 is a laptop processor with 4 cores and 4 threads, built on the Cherry Trail architecture. It launched in Jan 2016. Clocks run from 1.44 GHz base to 2.4 GHz boost. A 2-MB L3 cache backs the cores (1.1 MB per core). It addresses LPDDR3 memory up to 8 GB across 2 channels. The chip drops into the UTFCBGA1380 socket and exposes PCIe 2.0 (2 lanes). Rated TDP is 2.2 W. Notable platform capabilities: VT-x (Hardware Virtualization).

The Intel Atom x5-Z8550 scores 664 in single-core performance and 1,151 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 874 for overall performance, 1,678 for productivity performance, 1,828 for creator performance, 1,108 for engineering performance and 2,280 for gaming performance. Its multi-core throughput works out to 288 per core, 288 per thread and 530 per watt. Its computed efficiency index is 594. 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 x5-Z8550 scores 5,673 in integer math, 1,462 in floating-point math, 26,730 in compression, 361 in cryptography, 121 in physics simulation, 547 in vector SIMD, 4 in the prime sieve and 3,816 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 90% below in integer math, 97% below in floating-point math, 88% below in compression, 97% below in cryptography, 89% below in physics simulation, 96% below in vector SIMD, 94% below in the prime sieve and 83% 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 x5-Z8550 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 1.44 GHz and boosts up to 2.40 GHz.

The Intel Atom x5-Z8550 is a laptop processor, belongs to the Intel Atom X family, uses the Cherry Trail architecture, carries the codename Cherry Trail and is manufactured on a 14 nm process. It launched in Jan 2016.

The Intel Atom x5-Z8550 has 224 KB of L1 cache, 2 MB of L2 cache and 2 MB of L3 cache. That adds up to about 4.2 MB of cache, or 1.05 MB per core.

The Intel Atom x5-Z8550 has a 3-level cache hierarchy: L1 at 224 KB, L2 at 2 MB and L3 at 2 MB. L2 is the largest level and makes up about 47% of the cache listed here.

The Intel Atom x5-Z8550 supports LPDDR3 memory, addresses up to 8 GB of memory, uses 2 memory channels and runs memory at up to 1,600 MT/s. It does not support DDR5 and DDR4 memory.

The Intel Atom x5-Z8550 includes integrated graphics (HD Graphics 400) and clocks the graphics up to 0.60 GHz.

The Intel Atom x5-Z8550 uses the UTFCBGA1380 socket, supports PCI Express 2.0 and provides up to 2 PCIe lanes.
