Intel Celeron G3900

The Intel Celeron G3900 is a desktop processor from Intel, built on the Skylake architecture and the 14 nm process. It has 2 cores and 2 threads, a base clock of 2.80, 64 KB of L1 cache per core, 256 KB of L2 cache per core, and 4 MB of shared L3 cache. Its average benchmark score is 624, which places it at the 15th percentile among all CPUs in the database. Intel lists the part as Active production, with a release date of 2015-08-31 and part number SR2HV.

Single-Thread vs Multi-Thread Behavior

The fact pack contains two single-thread Cinebench results: Cinebench R20 single-core scores 107 and Cinebench R23 single-core scores 256. On the multi-thread side, Cinebench R15 multi-core scores 182, R20 multi-core scores 762, and R23 multi-core scores 1815. The gap between the single-core and multi-core results is large in both R20 and R23, but the absolute numbers are low. With 2 threads for 2 cores, the CPU cannot add logical threads beyond its physical cores, so these multi-core scores come from exactly two cores working together.

For real workloads, this split is important. A lightly threaded application such as a document editor or a basic web browser tends to be governed by the single-core result. The R20 single-core score of 107 and the R23 single-core score of 256 indicate that the CPU can handle a focused, non-demanding thread without the benefit of extra cores. Multi-threaded workloads, such as batch conversion, rendering, or running multiple background tasks at once, can use the multi-core score as a better guide. The R20 multi-core score of 762 and the R23 multi-core score of 1815 are higher than the respective single-core scores, which shows that the chip does gain throughput when both cores are occupied. Still, the 15th percentile position suggests that both single-thread and multi-thread standing are low in the wider CPU population.

The lack of a boost clock in the data reinforces the picture. There is no higher frequency state listed beyond the base clock of 2.80, so the benchmark results are generated from that fixed operating point. The practical consequence is that the CPU has no temporary frequency headroom in the data; every workload sees the same base clock limit.

Power and Thermals

The TDP is listed as 51. That places the G3900 in a moderate desktop thermal class. The processor is manufactured by Intel on a 14 nm process, with 1,400 million transistors and a die size of 150 mm². A 51 TDP part with two cores and integrated Intel HD 510 graphics is not a demanding thermal target. The data implies a basic desktop cooler is sufficient, not a high-end liquid or large tower solution.

The integrated graphics block is part of the same socket package, so the 51 TDP class applies to a CPU that also includes display capability. No boost clock is present in the fact pack, which means the power envelope is likely tied to the 2.80 base clock rather than to a variable frequency curve. The multiplier is not unlocked, so the processor does not offer user-controlled frequency adjustment through the multiplier. The 14 nm process and 150 mm² die size mean the thermal density is spread across a moderately sized chip, which supports the idea of a simple cooling solution.

How It Compares

Against the Intel Celeron 4305U, the G3900 has an identical average benchmark score of 624, and the deltaPct is 0. This is a perfect tie in the database’s aggregate comparison. Any difference between the two would appear only in specific tests, not in the average score.

Against the Intel Celeron N4505, the G3900 also faces an average score of 624, with a deltaPct of -0.1. The negative value places the G3900 a tenth of a percent behind the N4505 in the comparison. That is a negligible gap in practical terms; the two processors sit at the same performance tier.

Against the Intel Core i7-920XM, the G3900’s average score of 624 compares with 623 for the i7-920XM, and the deltaPct is 0.1. The G3900 is a tenth of a percent ahead on average. It is a very narrow lead over a Core i7 part with a slightly lower average score.

Against the Intel Core i5-2450M, the rival has an average score of 625, and the deltaPct is -0.2. The G3900 trails by two tenths of a percent. Across all four nearest rivals, the G3900 is inside a band from 623 to 625, so the database treats these processors as extremely close neighbors.

FAQ

Q: How many cores and threads does the Intel Celeron G3900 have?

A: It has 2 cores and 2 threads, meaning one thread per physical core.

Q: Does it include integrated graphics?

Benchmark Performance

The Cinebench scores in the fact pack are all low in absolute terms. In Cinebench R15, the multi-core score is 182. In Cinebench R20, the multi-core score is 762 and the single-core score is 107. In Cinebench R23, the multi-core score is 1815 and the single-core score is 256. The average benchmark score for the G3900 is 624, and the percentileVsAllCpus value is 15, meaning the processor sits at the 15th percentile among all CPUs in the database.

The nearest rivals form a tight cluster. The Celeron 4305U averages 624, the Celeron N4505 averages 624, the Core i7-920XM averages 623, and the Core i5-2450M averages 625. The G3900’s average score of 624 falls inside that group. The exact deltas are 0, -0.1, 0.1, and -0.2. These are tenths of a percent, so the G3900 is not separated from its closest competition by any meaningful margin in the aggregate data.

The R20 single-core score of 107 is the lowest single-core number among the Cinebench results in the fact pack. The R23 single-core score of 256 is higher, but cross-version Cinebench comparisons are not directly meaningful. Within each version, the multi-core score is much larger than the single-core score. The R20 multi-core score of 762 and the R23 multi-core score of 1815 show that two fully loaded cores can produce more throughput than one core, but those results remain low in the overall benchmark distribution. The 15th percentile position mirrors the narrow rival deltas: the G3900 is firmly in the low-performance range, and its nearest competition is equally close.

Platform and Compatibility

The G3900 is built for Intel Socket 1151. It supports DDR3 and DDR4 memory in a dual-channel configuration, with a memory bandwidth of 34.1 GB/s. ECC memory is not supported. The processor supplies PCIe Gen 3 with 16 lanes, and the fact pack labels those lanes as CPU only. The integrated graphics block is Intel HD 510, which means a discrete graphics card is not necessarily required for display output.

The market segment is Desktop, and the production status is Active. The part number is SR2HV. The base clock is 2.80, and there is no boost clock in the data. The multiplier is not unlocked, so the CPU does not provide multiplier-based overclocking. The lack of ECC support and the locked multiplier narrow the platform to consumer desktop use. Because the platform is built around Intel Socket 1151, any processor replacement would need to match that same socket and the supported DDR3/DDR4 memory families.

Who Should Consider It

The benchmark data points to a low-end desktop processor. The R20 single-core score of 107 and the R23 single-core score of 256 suggest that gaming workloads, which often depend heavily on single-thread performance, would not be a strength. The R20 multi-core score of 762 and the R23 multi-core score of 1815 are also low, so creation workloads such as rendering, video encoding, or compilation would be constrained by the 2-core/2-thread design.

For office-style work, the picture is more mixed. A simple word-processing task running on a single thread could be acceptable at the 2.80 base clock, and the integrated Intel HD 510 graphics may handle basic display tasks. But a user who keeps many background threads active or works with larger data files would likely feel the low thread count and low single-core score. The 15th percentile position is a clear warning for anyone expecting more than lightweight desktop responsiveness.

The G3900 appears best suited to light, focused workloads: basic office tasks, simple web browsing, and systems where a discrete GPU is not needed. It is not a match for demanding multi-threaded creation work, and its nearest rivals show that even a small delta of 0.1 or -0.2 percent separates it from processors that are already in the same low-scoring tier.
