Intel® Atom™ Z540
The Intel Atom Z540 is a laptop processor released on April 2, 2008. It has 1 core and 2 threads, a base clock of 1.86 GHz, a 2 W TDP and the FCBGA441 socket.
Overview
SummaryThe Intel Atom Z540 is a laptop processor with 1 cores and 2 threads. It launched in Apr 2008. It uses the FCBGA441 socket. Rated TDP is 2.4 W.
Performance
5 metricsThe Intel Atom Z540 scores 227 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 208 for engineering performance. Its multi-core throughput works out to 227 per core, 114 per thread and 95 per watt. 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 Atom Z540.
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.
