Intel Celeron G3950

The Intel Celeron G3950 is a dual-core desktop processor from Intel’s Kaby Lake architecture, built on a 14 nm process and released in early 2017. Benchmark data places it near the bottom of the overall CPU distribution, with a percentile rank of 17, meaning it outperforms roughly 17% of all tested processors. Its average benchmark score of 683 is virtually tied with a small cluster of older or low-power rivals, indicating that this chip sits at the entry-level threshold for modern desktop workloads.

Benchmark Performance

The G3950’s multi-core performance is modest, as shown by its Cinebench R23 multi-core score of 1985. This result aligns with its position in the 17th percentile, confirming that the processor is designed for basic tasks rather than demanding parallel workloads. In Cinebench R20 multi-core, the chip scores 833, while the older Cinebench R15 multi-core test yields 199. These scores scale consistently across versions, reflecting a stable but limited computational ceiling.

Single-core performance tells a similar story. The Cinebench R23 single-core score of 280 and Cinebench R20 single-core score of 117 are low relative to mainstream desktop parts, but they are internally consistent with the chip’s 3.00 GHz base clock and lack of turbo boost. Because the G3950 has no boost clock, its performance is entirely dependent on that fixed frequency, which explains why single-threaded results do not exceed expectations.

Compared to its nearest rivals, the G3950 is statistically indistinguishable in average score. The Intel Core m5-6Y57 has an average score of 684, which is 0.1% lower than the G3950’s 683. The Intel Xeon E5472 also scores 684, but the delta is reported as 0.1% in the opposite direction, meaning the G3950 is 0.1% ahead. Similarly, the Intel Core i3-4000M and Intel Xeon X5365 both have average scores of 682, with deltas of 0.2% favoring the G3950. These differences are negligible in real-world terms, placing the G3950 in a dead heat with a group of processors that range from a low-power mobile chip to legacy server Xeons.

Power and Thermals

The G3950 carries a TDP of 51 watts. This places it in a low-power class suitable for compact desktop builds and basic office machines. A 51-watt TDP does not require elaborate cooling; a stock Intel cooler or any basic air cooler is sufficient to maintain safe operating temperatures under sustained load. The 14 nm manufacturing process helps keep heat output manageable, and the lack of a boost clock means power draw remains flat during operation rather than spiking under turbo conditions.

For system builders, the 51-watt figure implies that power supply requirements are minimal, and thermal design can prioritize low noise over maximum cooling capacity. The processor’s dual-core, dual-thread configuration further reduces thermal strain, as only two cores generate heat. In essence, this is a chip that runs cool and quiet, making it an easy fit for small form factor cases or passively cooled systems, though the integrated graphics and memory controller still require basic airflow.

Who Should Consider It

The G3950 is best suited for users whose workloads are light and single-threaded in nature. Office productivity tasks such as word processing, spreadsheet management, and web browsing fall within its capability, given its modest single-core scores. The Cinebench R23 single-core score of 280 indicates that basic application responsiveness is acceptable, but anything more demanding will expose the processor’s limits.

For gaming, the G3950 is not a viable option for modern titles. Its multi-core score of 1985 in Cinebench R23 is far below what contemporary games require, and the dual-core, dual-thread design lacks the parallelism needed for recent game engines. Older or indie games with low system requirements might run, but performance will be inconsistent. Integrated Intel HD 610 graphics further restricts gaming to esports titles at low settings and resolutions.

Content creation is similarly out of reach. Video editing, 3D rendering, and large-scale photo manipulation rely heavily on multi-core performance, and the G3950’s Cinebench R20 multi-core score of 833 shows it is not equipped for such tasks. The processor is better viewed as a low-cost entry point for basic computing, where its 51-watt TDP and simple platform keep total system costs down without demanding high-end components.

Platform and Compatibility

The G3950 fits into the Intel Socket 1151 platform, which was shared by Kaby Lake and Skylake desktop processors. This socket supports DDR4 memory in a dual-channel configuration, with a memory bandwidth of 38.4 GB/s. The memory controller does not support ECC memory, so standard unbuffered DDR4 modules are required. The processor provides 16 PCIe Gen 3 lanes from the CPU, enough for a single graphics card or a few expansion cards, though the integrated Intel HD 610 graphics can handle display output without a discrete GPU.

The 14 nm Kaby Lake architecture is mature and widely supported by motherboards from that era. The production status is listed as Active, meaning the processor is still in production. The part number is SR32J, and the release date was January 2, 2017. Because the socket is older, upgrade paths are limited to other Socket 1151 processors from the same generation, but users looking for more performance would need to consider a different platform entirely. The lack of an unlocked multiplier means no overclocking headroom, so performance is fixed at the stock 3.00 GHz.

Single-Thread vs Multi-Thread Behavior

The G3950’s single-thread performance is its stronger attribute relative to its multi-thread performance, but both are low in absolute terms. The Cinebench R23 single-core score of 280 is higher than would be expected from a 17th-percentile chip, suggesting that the fixed 3.00 GHz clock provides decent responsiveness for single-threaded applications. In contrast, the multi-core score of 1985 is only about seven times the single-core score, which is low because the processor has just two cores and two threads.

This split has real implications for workloads. Single-threaded tasks like launching applications, scrolling through documents, and basic scripting will feel reasonably snappy given the clock speed. Multi-threaded tasks, however, will see minimal scaling because only two threads are available. The Cinebench R20 multi-core score of 833 versus the single-core score of 117 illustrates this: the multi-core score is roughly seven times higher, which is typical for a dual-core chip without hyper-threading. For users who run many background processes or parallel workloads, the G3950 will struggle, as each additional thread competes for one of only two execution units.

How It Compares

Intel Core m5-6Y57: This rival has an average score of 684, just 0.1% below the G3950. The m5-6Y57 is a low-power mobile chip, so the performance parity is notable, but the G3950 benefits from a desktop platform with more robust cooling and upgrade options.

Intel Xeon E5472: With an average score of 682, the E5472 is 0.1% behind the G3950. The E5472 is a much older server processor with a different architecture, yet its multi-core capabilities are roughly matched by the G3950’s newer dual-core design, highlighting the efficiency gains of the 14 nm process.

Intel Core i3-4000M: The i3-4000M scores 682, which is 0.2% lower than the G3950. This mobile i3 from the Haswell era offers similar average performance, but the G3950 has a newer architecture and lower power consumption, making it a more modern choice for basic desktops.

Intel Xeon X5365: This rival also scores 682, putting it 0.2% behind the G3950. The X5365 is a quad-core server chip from an older generation, but its average score is nearly identical to the dual-core G3950, demonstrating how far desktop processors have come in terms of per-core efficiency.
