Intel Atom Z3735G

Platform and Compatibility

The Intel Atom Z3735G is a Bay Trail-T generation part built on the Silvermont architecture, manufactured on Intel's 22 nm process with a 100 mm² die size. It uses the Intel BGA 592 socket, which is a soldered, non-upgradeable platform—the chip is permanently attached to the motherboard. This makes the Z3735G a fixed-platform solution; there is no CPU upgrade path beyond the original purchase.

Memory support is limited to DDR3, running through a single-channel memory bus with a peak bandwidth of 10.7 GB/s. The single-channel configuration is a notable constraint for this platform, as it halves available memory bandwidth compared to dual-channel designs, which can bottleneck memory-intensive workloads. ECC memory is not supported, so this is not a platform for error-correcting, mission-critical compute tasks.

The chip integrates HD Graphics, providing basic display output without the need for a discrete GPU. The PCIe support is not specified in the available data, but the lack of any discrete graphics or expansion options is consistent with the ultra-mobile, low-power positioning of the Bay Trail-T family. The production status is end-of-life, and the part number is SR1UD. The release date is April 8, 2014. Given the soldered BGA package and the absence of a scalable memory controller or PCIe expansion, this platform is best understood as a complete, sealed system-on-chip design for compact, low-power devices rather than a building block for a customizable desktop or server.

Who Should Consider It

The Z3735G is a 4-core, 4-thread processor with a base clock of 1333 MHz and a boost clock of 1833 MHz. Benchmark data shows a 50th percentile ranking among all CPUs, which places it in the middle of the performance distribution—but that middle ground is heavily skewed by the fact that the average benchmark score is effectively zero, indicating that this chip is not a meaningful contender in any performance-weighted comparison.

For gaming, this processor is not a realistic option. The integrated HD Graphics and the low clock speeds, combined with single-channel memory bandwidth of 10.7 GB/s, will struggle with any modern 3D title. The data does not support a gaming recommendation; instead, the Z3735G is suited for basic 2D applications and lightweight, casual use.

For content creation, the picture is similarly constrained. Multi-threaded performance is limited by the 4-thread count and the modest 1833 MHz boost ceiling. Video encoding, 3D rendering, or large photo editing tasks will be slow. The chip is more appropriate for document editing, web browsing, and media playback at low resolutions—tasks that do not demand sustained multi-core throughput.

The real use case for the Z3735G is basic office productivity and light consumption in a fanless, ultra-portable form factor. The 2 W TDP class (discussed below) makes it suitable for passively cooled tablets and compact laptops where battery life and silence take priority over speed. For a user whose workload is email, spreadsheets, and streaming video, the Z3735G is acceptable; for anyone needing responsiveness in heavier applications, the data indicates they should look elsewhere.

Benchmark Performance

The benchmark results for the Z3735G are sparse, with an empty benchmarks array and an average benchmark score of zero. In the absence of direct scores, the percentileVsAllCpus field provides the only quantitative anchor: the chip sits at the 50th percentile among all CPUs. This is a misleading statistic on its face—a 50th percentile ranking typically suggests median performance—but the zero average score and the lack of any nearest rivals indicate that this is a low-activity entry in the database, not a chip that competes with modern processors.

The nearestRivals array is empty, so no direct percentage deltas can be calculated against specific competitors. What can be interpreted from the data is the relationship between the clock speeds and the architecture. The base-to-boost delta is 500 MHz (from 1333 to 1833 MHz), which is a 37.5% increase in clock frequency under load. This boost behavior is typical of a short-duration turbo, meaning sustained workloads will likely fall back toward the base clock, limiting multi-threaded throughput.

In practical terms, the 4 cores at 1333–1833 MHz will deliver single-thread performance that is adequate for basic instruction streams, but the lack of any rival comparisons in the database means there is no evidence of competitive standing. The 50th percentile ranking should be read with caution: it places this chip in the lower half of actively benchmarked CPUs when considering the full distribution, but the zero average score suggests it has rarely been tested, and when it has, the results were negligible. Benchmark results indicate this is a processor for which sustained performance metrics are not a selling point; it is a low-power part where the performance envelope is defined by efficiency, not speed.

How It Compares

There are no nearest rivals listed in the FACT PACK for the Intel Atom Z3735G. This absence is itself informative: the database contains no directly comparable CPUs with measured score deltas, which means the Z3735G occupies a niche that is either too old or too low-power to attract head-to-head benchmarking against contemporary parts.

Without rival data, the comparison must be made on architectural merits alone. The Silvermont architecture is a 22 nm design that predates Intel's more efficient and higher-performing Core and newer Atom families. The 4-thread limit and 2 MB L2 cache (with 56 KB L1 per core) place it in the entry-level mobile segment. Against a modern low-power chip, the Z3735G would likely trail in both single-thread and multi-thread scores due to its lower clock ceiling and older microarchitecture, but no percentage can be stated because no rival data exists in the pack.

The absence of any nearestRivals entries also means there is no percentile delta to cite. The only positional data is the 50th percentile overall, which is a global rank, not a relative comparison. In a field with no direct competitors, the Z3735G stands alone as a legacy part, and the data supports treating it as such: it is not a benchmark contender, and its value lies in its historical role in low-cost tablets and mini-PCs, not in performance competition.

Single-Thread vs Multi-Thread Behavior

The Z3735G has 4 cores and 4 threads, meaning there is no Hyper-Threading; each core handles exactly one thread. This is a critical distinction for multi-threaded workloads, as a modern 4-core/8-thread chip would effectively double the thread count. The base clock of 1333 MHz and boost of 1833 MHz apply to all cores, but the boost is likely a single-core or short-duration turbo, so multi-threaded loads will likely settle closer to the base clock.

Single-thread performance is dominated by the 1833 MHz boost clock and the Silvermont core design. Silvermont is an out-of-order architecture, which helps with instruction-level parallelism, but the clock speed is low by modern standards. For everyday tasks like web browsing or word processing, the single-thread boost will be sufficient for responsive UI interactions, but the lack of a high sustained clock means that any task requiring a long single-thread burst (e.g., script-heavy pages) will feel sluggish.

Multi-thread behavior is constrained by the 4-thread limit and the single-channel memory bus. A 10.7 GB/s bandwidth ceiling means that even if all 4 cores are active, they will compete for a narrow memory pipe. This is particularly detrimental to workloads that stream data, such as video transcoding or database queries. The 2 MB L2 cache helps mitigate some memory pressure, but it is small relative to modern chips. The data shows a clear split: single-threaded tasks get a modest boost advantage, while multi-threaded tasks are hamstrung by thread count and memory bandwidth. For a user, this means the chip is better suited to interactive, single-threaded tasks than to batch processing.

Power and Thermals

The Intel Atom Z3735G has a TDP of 2 W. This is an exceptionally low thermal design power, placing it in the ultra-low-power class typically reserved for fanless mobile devices. A 2 W TDP means the chip can be cooled by a passive heatsink or even a simple thermal pad, with no active fan required. This has direct implications for the cooling tier: any capable air cooler designed for low-power embedded or mobile platforms will be more than sufficient. In fact, the thermal requirement is so low that a dedicated aftermarket cooler is unnecessary; the chassis design itself will dissipate the heat.

The 22 nm process node and the Silvermont architecture are key contributors to this low power draw. The 100 mm² die size is small, and the core count is limited to 4, which keeps power density low. The absence of a high boost clock — capped at 1833 MHz — further reduces peak power consumption. The TDP of 2 W is a sustained figure, but the boost behavior may temporarily increase power draw above that level; still, the thermal envelope is so small that even a brief boost will not require active cooling.

For system integrators, the 2 W TDP class means that the Z3735G can be placed in thin, light, and completely silent devices. Battery life in a tablet or small laptop will be dominated by the display and other components, not the CPU. The trade-off is that the performance ceiling is equally low, but for a chip that draws 2 W, the benchmark percentile of 50 and the zero average score suggest that efficiency is the primary design goal, not throughput. Thermal management is trivial, and the cooling tier is effectively "passive" — any enclosure with minimal airflow will suffice.
