Intel Atom Z625

Intel Atom Z625 is a single-core, single-thread mobile processor from Intel’s Atom family, built on the 45 nm Lincroft architecture. Launched in May 2010 and now end-of-life, this chip targets low-power, basic computing tasks rather than performance-intensive workloads.

Benchmark Performance

The benchmark data for the Intel Atom Z625 is effectively a blank slate: the processor has no recorded benchmark scores, an average benchmark score of zero, and no nearest rivals listed for comparison. The percentile rank against all CPUs sits at the 50th mark, which is a neutral placement—neither outperforming nor underperforming a hypothetical median chip, but in practice this reflects an absence of measurable data rather than a meaningful performance tier.

With a single core and a single thread running at a base clock of 1900 MHz, the Z625 is architecturally limited to sequential processing. There is no boost clock capability, so the 1900 MHz figure is the maximum sustained speed. The L1 cache is 64 KB per core, and L2 cache is 512 KB per core—small but adequate for the intended workload. The lack of any benchmark scores means quantitative comparisons against rivals are impossible; the data does not support claims of being faster or slower than any specific competitor.

The 50th percentile ranking should not be misread as "average performance." It is a default or placeholder value in the absence of test results. For context, any modern processor with even entry-level benchmark scores would far exceed this chip’s capabilities, but the FACT PACK provides no such comparative numbers. The practical takeaway: this is a processor whose performance is defined by its specifications—single-core, 1.9 GHz, no turbo—not by any measured output.

Platform and Compatibility

The Intel Atom Z625 uses the Intel BGA 518 socket, which is a soldered, non-upgradeable platform. It supports DDR2 memory only, with no ECC capability. The integrated graphics are listed as "on certain motherboards (Chipset feature)," meaning the GPU is not on the CPU die but depends on the specific chipset configuration of the motherboard.

The processor is based on the 45 nm process node from Intel’s foundry, with 140 million transistors on a 65 mm² die. The architecture is "Atom" with the codename "Lincroft," and the generation is listed as "Atom (Lincroft)." The multiplier is unlocked, but this is of limited practical use given the single-core design and low thermal envelope.

PCIe support is not specified in the data, so no assumptions can be made about expansion slots or lane counts. The memory bus and memory bandwidth are also unspecified. The upgrade path is effectively nonexistent: BGA 518 is a fixed socket, and this is a mobile-market chip, so it is not designed for desktop builds or future component swaps. The production status is end-of-life, meaning no new units are being made, and replacement parts would come from existing stock or used markets.

For compatibility, the Z625 is strictly a legacy platform. It pairs with DDR2 memory, which is obsolete, and relies on motherboard-integrated graphics. The lack of PCIe data suggests this is not a platform for discrete GPUs or high-bandwidth peripherals. The chipset feature for graphics implies the motherboard must be specifically designed for this Atom variant, further limiting motherboard choices.

Who Should Consider It

Given the absence of benchmark scores, recommendations must be grounded in the raw specifications. The Z625 is a single-core, 1.9 GHz processor with 64 KB L1 and 512 KB L2 cache. This is suitable for basic, single-threaded tasks: lightweight text editing, simple web browsing with minimal tabs, or legacy industrial applications that require low power consumption and a fixed, small form factor.

For gaming, this processor is not viable. Modern games require multi-core CPUs, and even older titles would struggle with a single thread at 1.9 GHz. The integrated graphics, dependent on the motherboard chipset, would be a further bottleneck, but no specific GPU performance data exists in the FACT PACK. The data does not support any gaming recommendation.

For content creation, the Z625 is equally unsuitable. Video encoding, 3D rendering, or photo editing demand multiple cores and higher clock speeds. The single thread and modest cache would cause severe slowdowns. Office productivity is a borderline case: basic word processing and spreadsheets would function, but any multitasking—running an email client alongside a browser—would likely cause stuttering.

The intended market segment is "Mobile," so this chip is best suited for embedded devices, thin-and-light netbooks from the early 2010s, or fanless industrial controllers. The 2-watt TDP class (see Power and Thermals) makes it attractive for battery-powered or passively cooled systems where performance is secondary to power efficiency. If the workload is a single, simple process running continuously, the Z625 can handle it. If the workload involves any modern multitasking, look elsewhere.

How It Compares

The nearestRivals field in the FACT PACK is empty. There are no rival names, scores, or deltaPct values to analyze. This means the Z625 cannot be positioned against any specific competitor. The data offers no comparison points, so any statement about being ahead of or behind a rival would be fabricated.

In the absence of rival data, the only comparison is against the broader CPU landscape via the 50th percentile rank. This is a neutral placeholder, not a measured outcome. The lack of rivals also suggests this chip is so far outside mainstream testing that no comparable products have been benchmarked in the same database. For practical purposes, the Z625 sits alone in its category: a single-core, 1.9 GHz Atom with no measurable performance footprint.

If the data had included rivals, the analysis would focus on deltaPct values—how much faster or slower the Z625 is in percentage terms. Without those numbers, the honest conclusion is that no comparative analysis is possible from the provided facts.

Power and Thermals

The Intel Atom Z625 has a TDP of 2 watts. This is an extremely low power envelope, typical of the Atom Lincroft generation designed for fanless, passively cooled mobile devices. The 45 nm process node and single-core design contribute to this minimal thermal output.

For cooling, a 2-watt TDP implies that no active cooling is required. A simple heatsink or even a thermal pad against the chassis would suffice. There is no data on maximum temperature or thermal throttling, but the low TDP class suggests the chip runs cool under normal operation. The base clock of 1900 MHz is the maximum speed, with no boost clock, so there is no thermal headroom for temporary speed increases that would demand better cooling.

The practical implication: any motherboard or device that houses this chip must provide basic heat dissipation, but a fan is unnecessary. The power delivery requirements are also minimal, though the FACT PACK does not specify voltage or current figures. The 2-watt rating places this in the same class as other ultra-low-power embedded processors, but without rival data, no direct comparison is possible.
