Intel Celeron G1101

The Intel Celeron G1101 is a dual-core, dual-thread processor from the Westmere generation, built on a 32 nm process with a base clock of 2.27 GHz. It sits in the lowest performance percentile of the benchmark database, with a percentile rank of 1, indicating that it outperforms only 1% of all CPUs tracked. Its average benchmark score is 317, placing it in a tight cluster of similarly aged, low-power processors where the differences between rivals are measured in fractions of a percent rather than meaningful margins.

Benchmark Performance

The Celeron G1101’s benchmark results are remarkably consistent across rendering workloads, with scores that scale predictably from multi-threaded to single-threaded tests. In Cinebench R15 multi-core, the chip scores 92 points, while the R20 multi-core test yields 387 points, and the R23 multi-core test produces 923 points. These numbers place the processor firmly at the entry level, with performance that is adequate for basic tasks but far below any modern standard. The single-core results tell a similar story: 54 points in R20 single-core and 130 points in R23 single-core, both of which are among the lowest recorded for any processor in the database.

When compared to its nearest rivals, the G1101’s performance is essentially indistinguishable from its direct competitors. The average benchmark score of 317 puts it 0.3% ahead of the AMD Athlon 64 X2 5600+, which scores 316, and 0.5% ahead of the AMD Athlon II X2 235e, which scores 315. Conversely, it trails the AMD Athlon II X2 210e by 0.3% (318 vs. 317) and the Intel Core i7-620UM by 0.5% (319 vs. 317). These deltaPct values are well within the margin of run-to-run variance, meaning that in practice, the G1101 performs on par with all four of its closest rivals.

The multi-core scores reveal a processor that is heavily constrained by its dual-core, dual-thread design. The Cinebench R23 multi-core score of 923 is only slightly more than seven times the single-core score of 130, which is a typical ratio for a chip with no hyper-threading and a modest clock speed. In absolute terms, these numbers suggest that the G1101 is suitable for light office work, web browsing, and legacy applications, but it will struggle with any modern multi-threaded workload such as video encoding, 3D rendering, or software compilation. The single-core scores of 130 in R23 and 54 in R20 are similarly low, indicating that even basic single-threaded tasks like spreadsheet recalculations or PDF rendering will feel sluggish by contemporary standards.

How It Compares

Against the AMD Athlon 64 X2 5600+, the Celeron G1101 holds a razor-thin 0.3% advantage in average benchmark score. Both processors are dual-core designs from the same era, and the data shows no meaningful performance difference between them. The G1101’s newer 32 nm process and support for DDR3 memory do not translate into any measurable benchmark advantage, as the 0.3% delta is within the noise of typical benchmark variance.

The AMD Athlon II X2 210e edges out the G1101 by 0.3%, with an average score of 318 versus 317. This is a negligible margin, but it does suggest that the Athlon II X2 210e, which is also a dual-core part, holds a slight edge in the aggregate of all benchmark results. The G1101’s higher TDP of 73 watts does not yield any performance benefit over this rival, which is worth noting for anyone comparing power efficiency.

The Intel Core i7-620UM is the strongest competitor in this group, leading the G1101 by 0.5% with an average score of 319. The i7-620UM is a low-voltage mobile processor, and its slight advantage is notable given that it is designed for power-constrained laptops rather than desktop or workstation use. The G1101, despite its higher TDP, cannot overcome this deficit, indicating that the i7-620UM’s architecture and clock management are more efficient.

The AMD Athlon II X2 235e trails the G1101 by 0.5%, scoring 315 versus 317. This is the only rival in the group that the G1101 beats by a measurable, though still tiny, margin. The 0.5% delta is the largest gap in this comparison set, but it remains far too small to be perceptible in real-world use. All four rivals, including the G1101, are effectively tied in performance, making benchmark scores the only way to differentiate them.

Who Should Consider It

The Celeron G1101 is a processor for legacy systems and basic computing tasks, not for demanding applications. Its Cinebench R23 multi-core score of 923 and single-core score of 130 indicate that it is suited for word processing, email, and light web browsing, where multi-threaded performance is not a factor. Users running older operating systems or single-threaded business applications will find it adequate, provided they do not expect fast response times.

For gaming, the G1101 is not a viable option by modern standards. The low single-core score of 130 in R23 means that most contemporary games, which rely heavily on strong single-thread performance, will run poorly or not at all. The integrated Intel HD graphics further limit its utility, as even older titles will require a discrete GPU, and the processor’s overall performance will bottleneck any such GPU. The data shows this is a chip for productivity, not entertainment.

Content creation is entirely out of scope for this processor. The multi-core score of 923 in R23 is roughly one-tenth of what a modern mid-range CPU achieves, making tasks like video editing, 3D modeling, or photo batch processing impractically slow. The 2 MB shared L3 cache and dual-channel DDR3 memory support with 17.1 GB/s bandwidth further constrain memory-intensive workloads. The G1101 is best viewed as a spare part for repairing old machines or as a low-cost server/workstation processor for tasks that require ECC memory support, which it does offer.

Office workers running spreadsheet, database, or terminal applications on legacy hardware will find the G1101 functional, though not fast. Its 2.27 GHz base clock and dual-core design are sufficient for single-threaded office tasks, and the ECC memory support makes it a candidate for basic file servers or network appliances. However, anyone considering this processor for a new build should look elsewhere, as even the cheapest modern dual-core part will outperform it by a wide margin.

Single-Thread vs Multi-Thread Behavior

The Celeron G1101 exhibits a performance profile that is consistent with its dual-core, dual-thread design, with no hyper-threading to extract additional parallelism from each core. The Cinebench R23 scores show a multi-thread to single-thread ratio of approximately 7.1:1 (923 vs. 130), which is typical for a processor with two physical cores and a modest 2.27 GHz clock. This ratio indicates that the chip scales well across its two cores, but the absolute performance ceiling is extremely low.

In single-threaded workloads, the G1101’s score of 130 in R23 places it at the very bottom of the database, with only 1% of CPUs scoring lower. This means that any application that relies on a single thread, such as legacy games, certain database queries, or script interpreters, will run at a pace that feels unresponsive. The 54-point R20 single-core score reinforces this, showing that the Westmere architecture, despite its 32 nm process, cannot compete with even entry-level processors from the last decade.

Multi-threaded behavior is marginally better, with the R23 multi-core score of 923 being roughly seven times the single-core result. This scaling is efficient for a two-core part, but the absolute numbers are still too low for any serious multi-threaded work. The 387-point R20 multi-core score and 92-point R15 multi-core score both indicate that the processor can handle two concurrent threads without significant contention, but it will max out quickly. The 2 MB shared L3 cache helps mitigate some of the latency of the dual-channel DDR3 memory, but the 17.1 GB/s memory bandwidth is a hard limit for data-intensive tasks.

The real-world takeaway is that the G1101 is a single-thread-first processor. Its modest single-core performance is adequate for simple, interactive tasks, while its multi-core performance is only useful for background processes or light parallel workloads. The data shows no scenario where the G1101 excels, but its predictable scaling and low power draw (73 W TDP) make it a predictable, if unimpressive, choice for legacy systems.
