Atom Z540 Clock Speeds
Base and boost frequencies
Clock speed is a critical factor in Atom Z540 benchmark performance, measured in GHz. The base clock represents the guaranteed operating frequency, while the boost clock indicates maximum single-core performance under optimal conditions. Higher clock speeds translate to faster single-threaded performance, which is essential for gaming and applications that don't fully utilize multiple cores. The Atom Z540 by Intel can dynamically adjust its frequency based on workload and thermal headroom.
Intel's Atom Z540 Cache Hierarchy
L1, L2, L3 cache sizes
Cache memory is ultra-fast storage built directly into the Atom Z540 processor die. L1 cache provides the fastest access for frequently used data, while L2 and L3 caches offer progressively larger storage with slightly higher latency. Larger cache sizes significantly improve CPU benchmark scores by reducing memory access times. The Atom Z540's cache configuration is optimized for both gaming performance and productivity workloads, minimizing data fetch delays during intensive computations.
Atom Architecture & Process
Manufacturing and design details
The Intel Atom Z540 is built on Intel's 45 nm manufacturing process, which determines power efficiency and thermal characteristics. Smaller process nodes allow for more transistors in the same space, enabling higher performance per watt. The architecture defines how the processor handles instructions and manages data flow, directly impacting benchmark results across different workload types. Modern CPU architectures like the one in Atom Z540 incorporate advanced branch prediction and out-of-order execution for optimal performance.

Atom Z540 Benchmark Scores
No benchmark data available for this CPU.
About Intel Atom Z540
The Intel Atom Z540 is a mobile processor from Intel, built on the Atom architecture and codenamed Silverthorne. It belongs to the Atom (Silverthorne) generation and was released on 2008-04-01. The chip has 1 core and 2 threads, with a base clock of 1867.00 MHz and no boost clock listed. Manufactured on a 45 nm process at Intel, the die contains 47 million transistors in a 26 mm² area. The part number is SLB2M, the production status is End-of-life, and no series designation is recorded.
Benchmark Performance
The benchmark record for the Intel Atom Z540 is sparse. The benchmarks array is empty, and the average benchmark score is 0. That zero is the only score value available for this SKU. The percentileVsAllCpus field places the Atom Z540 at the 50th percentile of all CPUs in the database. A 50th percentile is the exact midpoint of a ranked list, so the part is positioned in the middle of the aggregate CPU distribution rather than in the top or bottom half.
That median placement is difficult to interpret as a measured performance result because the average benchmark score is 0. A zero score alongside an empty benchmarks array suggests that no non-zero benchmark submission exists for this processor. The nearestRivals array is also empty. There are no rival names, no rival benchmark scores, and no deltaPct values in the record. Consequently, no percentage lead or deficit versus any named CPU can be calculated from this data.
The performance narrative is therefore limited. The data shows a CPU that sits at the 50th percentile of all CPUs while carrying an average benchmark score of 0. Without nearestRivals, the record cannot support any specific statement such as “ahead of rival X by Y%” or “behind rival Z by Y%.” The only numerical performance landmarks are the median percentile rank and the zero average score. In that sense, the benchmark field communicates an unmeasured SKU rather than a battle-tested processor.
Platform and Compatibility
The Intel Atom Z540 uses Intel BGA 441 as its socket/package interface. The architecture is Atom, the codename is Silverthorne, and the generation field is given as Atom (Silverthorne). The process node is 45 nm, and the foundry is Intel. The physical die measures 26 mm² and contains 47 million transistors. Those figures define the manufacturing footprint of the part.
Cache details are listed as 56 KB of L1 per core and 512 KB of L2 per core. Because the Z540 contains a single core, the total cache values match the per-core values: 56 KB of L1 cache and 512 KB of L2 cache. No L3 cache is listed. The totalL3 and vCache3d fields are empty, so any large tertiary cache or specialized 3D cache capability is not part of this data record.
Memory support is not documented. The memorySupport, memoryBus, and memoryBandwidth fields are all null, which means the record does not identify supported memory types, bus width, or bandwidth limits. ECC memory is not supported, as the eccMemory field is false. No PCIe information is provided, leaving expansion slot capability unspecified. Integrated graphics are described with the value “On certain motherboards (Chipset feature).” That phrasing places graphics capability outside the CPU chip, tied to the motherboard chipset on select boards.
The multiplier is locked because multiplierUnlocked is false. The market segment is Mobile, matching the low-power positioning of the chip. The release date is 2008-04-01, and production status is End-of-life. The part number is SLB2M, and the series field is null. From an upgrade-path perspective, the data offers only two relevant facts: the package is Intel BGA 441, and the production status is End-of-life. No socketed upgrade path or board compatibility list is included in the record.
How It Compares
The nearestRivals array for the Intel Atom Z540 is empty. There are no nearest-rival entries to profile, so no head-to-head comparisons against named processors are available. There are no rival scores and no deltaPct values to quote. The only comparative metric in the entire record is percentileVsAllCpus, which is 50.
That 50th percentile places the Z540 at the midpoint of the all-CPU ranking in the database. It is neither a high-ranking nor a low-ranking placement. However, because the average benchmark score is 0, that midpoint is not backed by a positive performance sample. The percentile cannot be interpreted as evidence that the processor outperforms half of the CPUs in the database, since the score field itself is zero.
No exact percentage comparison can be derived from the available data. There is no nearestRivals object containing a rival name or a deltaPct. As a result, the Z540 cannot be described as faster or slower than any specific processor in the dataset. The comparison section for this part is defined by the absence of rival data. The only takeaway is the median all-CPU percentile combined with a zero average benchmark score.

Power and Thermals
The Intel Atom Z540 has a TDP of 2 W. That single figure defines the power class of the part: a very low thermal envelope. A 2 W TDP implies a cooling solution at the minimal end of the scale. The data does not specify a cooler model, heatsink size, airflow requirement, or fan type, so the cooling tier cannot be described beyond that qualitative implication.
The chip operates at a base clock of 1867.00 MHz with no boost clock, so the thermal design is tied to one fixed clock specification. The 45 nm process node, 47 million transistors, and 26 mm² die are the physical characteristics behind that 2 W thermal envelope. The locked multiplier also prevents multiplier-based frequency changes, based on the multiplierUnlocked false field.
The production status is End-of-life, and the release date is 2008-04-01, giving the product a defined lifecycle position. The market segment is Mobile, which is consistent with the low TDP. Integrated graphics are tied to a motherboard chipset feature rather than to the CPU die, meaning the CPU’s thermal contribution is separate from display logic in the record. Overall, the 2 W TDP is the key power and thermal figure, and the data supports only one conclusion: the cooling tier implied is very light.
