Intel Celeron G1630

The Intel Celeron G1630 is a dual-core desktop processor from the Ivy Bridge generation, aimed at the entry-level segment. Its benchmark data places it in the 9th percentile of all CPUs, indicating that it is designed for fundamental computing tasks rather than demanding workloads. The processor operates at a base clock of 2.80 GHz with no boost capability, and its performance metrics across various Cinebench versions provide a clear picture of its capabilities relative to a small cluster of closely matched rivals.

Who Should Consider It

The benchmark results indicate that the Celeron G1630 is suitable for basic office productivity, web browsing, and light document creation. Its Cinebench R23 multicore score of 1450 and single-core score of 204 suggest that it can handle everyday applications like word processing and spreadsheet management without significant strain. Users whose primary workloads involve email, video conferencing, and legacy software will find this processor adequate, especially when paired with an SSD for system responsiveness.

For gaming, the data is less encouraging. The processor's low average benchmark score of 499 and its 9th percentile ranking imply that it is not well-suited for modern 3D titles or any game that requires more than two processing threads. The integrated Intel HD graphics further limit its gaming potential, as the processor lacks the raw computational power to drive high frame rates even in older or less demanding games. Enthusiasts or gamers should look elsewhere, as the Celeron G1630 is fundamentally a productivity-focused chip.

Content creation, such as video editing, 3D rendering, or large-scale photo manipulation, is out of scope for this processor. The Cinebench R20 multicore score of 609 and R15 multicore score of 146 are far below what these tasks require. However, for users who only need a machine for email, spreadsheets, and web-based applications, the G1630 delivers baseline functionality. The data suggests that it is a stopgap or secondary PC solution, not a primary workhorse for compute-intensive professions.

Power and Thermals

The Celeron G1630 has a thermal design power (TDP) rating of 55 watts. This is a modest figure that places it in the mainstream desktop power envelope, rather than the ultra-low-power segment. A 55W TDP means that a standard air cooler with a small heatsink and fan is more than sufficient to manage its thermal output. The processor does not require exotic cooling solutions, such as large tower coolers or liquid systems, and it will operate quietly under typical office workloads.

The 22 nm process node used for the Ivy Bridge architecture contributes to its thermal efficiency. The die size is 94 mm², which is relatively small, and this helps with heat dissipation across the integrated heat spreader. In practice, the data implies that the G1630 will run cool even under sustained load, as its dual cores and lack of boost clocks generate limited heat. For system builders, this means that a basic case with adequate airflow is sufficient, and there is no need for high-end thermal management components.

The lack of a boost clock is notable in thermal discussions. Because the processor always runs at 2.80 GHz, its power draw remains consistent, avoiding the transient spikes seen in processors with dynamic frequency scaling. This predictability is beneficial for small form factor builds where cooling is constrained. The 55W TDP also indicates that the processor is compatible with a wide range of motherboards that support Intel Socket 1155, as long as the board's power delivery is rated for this class of chip.

Single-Thread vs Multi-Thread Behavior

The split between single-thread and multi-thread scores reveals a processor that is heavily reliant on its two physical cores, with no hyper-threading support. In Cinebench R23, the single-core score is 204, while the multicore score is 1450. This translates to a multicore scaling factor of roughly 7.1 times the single-core result, which is unusually high and indicates that the multi-core test is not purely a linear function of core count; rather, it reflects the processor's ability to sustain load across both cores simultaneously.

For real workloads, this means that applications which are single-threaded, such as older games or certain legacy business software, will perform at a level consistent with the 204 single-core score. This is adequate for basic responsiveness but will feel sluggish in tasks that require heavy JavaScript execution or complex spreadsheet recalculation. Conversely, multi-threaded workloads, such as batch photo resizing or file compression, will see a benefit from the dual cores, as the multicore score of 1450 suggests that parallel tasks are handled with reasonable efficiency for an entry-level chip.

The Cinebench R20 scores follow a similar pattern: 85 for single-core and 609 for multicore. The gap between these scores indicates that the processor does not suffer from thermal throttling during multi-threaded workloads, as the power envelope is low enough to sustain full load on both cores. However, the absolute scores are low, meaning that any task requiring more than a few minutes of sustained CPU activity will expose the processor's limitations. Users should interpret this as a chip that excels at short, bursty tasks rather than prolonged compute sessions.

How It Compares

The nearest rival to the Celeron G1630 is the AMD A4 PRO-3340B, which has an average benchmark score of 500 against the G1630's 499. The delta percentage is -0.1, meaning that the AMD part is effectively tied with the Intel processor in overall performance. Both are entry-level chips, and the data shows that neither has a meaningful advantage in typical workloads. Users choosing between them would likely be swayed by platform features rather than raw speed.

The Intel Celeron G1820 is another direct competitor, with a score of 500 and a delta of -0.2. This is also a virtual tie, and the G1820 belongs to the same Haswell generation, though it uses a different socket. The performance parity means that system integrators and users upgrading from either chip would see no tangible difference in application speed. The G1630's Ivy Bridge architecture is older, but the benchmark results show that this does not translate into a performance deficit.

The Intel Core i3-2100T is a more interesting comparison, as it is a dual-core processor with hyper-threading, giving it four threads. Its average score is 502, with a delta of -0.5 against the G1630. Despite having twice the thread count, the i3-2100T is only marginally faster, which suggests that the G1630's higher base clock of 2.80 GHz helps close the gap that hyper-threading might otherwise create. This implies that for single-threaded tasks, the G1630 is competitive with the i3-2100T, but the i3 pulls ahead in multi-threaded scenarios due to its additional threads.

The AMD Athlon II X3 440 is a triple-core processor with a score of 503 and a delta of -0.8. This is the largest performance difference in the rival group, yet it is still less than 1%. The Athlon's three cores give it an advantage in multi-threaded workloads, but its older architecture and lower clock speed negate some of that benefit. The data shows that the G1630 is remarkably consistent with these rivals, all of which sit within a 1% performance band, indicating that this segment of the market is highly competitive with no clear winner.

Platform and Compatibility

The Celeron G1630 uses the Intel Socket 1155, which is associated with the Ivy Bridge and Sandy Bridge architectures. This socket supports DDR3 memory in a dual-channel configuration, and the processor has an integrated memory controller that runs at the base clock. The lack of ECC memory support is notable for users considering this chip for a home server or NAS, as error-correcting memory is not available, limiting its suitability for data integrity-critical applications.

For PCIe, the G1630 provides Gen 3 with 16 lanes from the CPU. This is a standard configuration for a desktop processor of this era, and it allows for a single discrete graphics card to run at full x16 bandwidth. However, the processor's low performance scores suggest that pairing it with a high-end GPU would create a significant bottleneck, as the CPU would struggle to feed frames to the graphics card in gaming scenarios. The 16 lanes are also sufficient for a single NVMe SSD via an adapter, though the processor's limited PCIe lanes mean that expansion options are constrained.

The integrated graphics are listed as Intel HD, which is the basic GPU included with the processor. This is suitable for display output and video playback but is not designed for gaming or GPU-accelerated tasks. The upgrade path from this platform is limited, as Socket 1155 is an older standard, and users would need to replace the motherboard to move to a newer processor generation. The part number is SR16A, and the processor was released on August 31, 2013, making it a decade-old design that is now firmly in the legacy category.

Benchmark Performance

The Cinebench R23 multicore score of 1450 places the Celeron G1630 in a specific performance tier. When compared to the nearest rivals, this score is consistent with the average benchmark scores, which range from 499 to 503. The G1630's R23 multicore score of 1450 is the highest absolute number in its benchmark suite, yet it is still far below what modern processors achieve, reinforcing its position at the bottom of the desktop hierarchy.

In Cinebench R20, the multicore score is 609 and the single-core score is 85. The ratio between these scores is approximately 7.2, which is higher than typical dual-core processors, indicating that the G1630 is efficient at utilizing its two cores for parallel workloads. However, the absolute single-core score of 85 is very low, suggesting that the processor's Ivy Bridge architecture, despite its 22 nm process, is limited by its low clock speed and lack of architectural improvements found in later generations.

The Cinebench R15 multicore score of 146 is the lowest among the benchmark results, which is expected given that R15 is an older test that often produces lower scores. The average benchmark score of 499 is a composite metric that aligns closely with the rival group, where the AMD A4 PRO-3340B scores 500, the Intel Celeron G1820 scores 500, the Intel Core i3-2100T scores 502, and the AMD Athlon II X3 440 scores 503. The delta percentages are all negative for the G1630, ranging from -0.1% to -0.8%, but these differences are negligible in real-world usage.

The percentile ranking of 9 indicates that the G1630 is in the bottom 10% of all processors tested. This is a stark indicator of its performance class. The data shows that it is not a processor for any task that requires significant computational power, but it is sufficient for basic, low-intensity workloads. The benchmark results collectively paint a picture of a chip that is competitive with its immediate rivals but utterly outclassed by anything above the entry-level segment.
