The base clock represents the guaranteed operating frequency, while the boost clock indicates maximum single-core performance under optimal conditions. Higher clock speeds translate to faster single-threaded performance, which is essential for gaming and applications that don't fully utilize multiple cores. The Celeron G1820TE by Intel can dynamically adjust its frequency based on workload and thermal headroom.
Intel's Celeron G1820TE Cache Hierarchy
L1, L2, L3 cache sizes
Cache memory is ultra-fast storage built directly into the Celeron G1820TE processor die. L1 cache provides the fastest access for frequently used data, while L2 and L3 caches offer progressively larger storage with slightly higher latency. Larger cache sizes significantly improve CPU benchmark scores by reducing memory access times. The Celeron G1820TE's cache configuration is optimized for both gaming performance and productivity workloads, minimizing data fetch delays during intensive computations.

About Intel Celeron G1820TE
The Intel Celeron G1820TE is a dual-core desktop processor built on Intel's Haswell architecture and 22 nm process, running at a fixed 2.20 GHz with no turbo boost. It offers 2 threads, 3 MB of shared L3 cache, and a 54 W TDP, and its benchmark results place it in the 4th percentile of all CPUs, with an average score of 372 across the test suite. This is an entry-level part designed for basic computing, and its performance data confirms that position.
Benchmark Performance
The G1820TE delivers very low absolute scores across all measured workloads. In Cinebench R15, it reaches 87 points multi-core; in R20, 364 multi-core and 51 single-core; in R23, 867 multi-core and 122 single-core. Geekbench results show 707 multi-core and 407 single-core. The single-core numbers are especially telling: a Cinebench R23 single-core score of 122 is near the floor for modern processors, and the Geekbench single-core figure of 407 is similarly modest. The multi-core scores, while higher, are still extremely limited because the chip has only two physical cores and no hyper-threading.
Relative to its nearest rivals, the G1820TE is effectively tied. Its average benchmark score of 372 is within 1% of all four listed competitors. The Intel Celeron 1020M posts an average score of 372, which is 0.1% lower; the AMD A8-5545M also scores 372, but 0.1% higher; the Intel Core i7-660UM averages 375, 0.9% lower; and the AMD Phenom II X2 B57 averages 368, 1% higher. These deltas are negligible in practice, meaning the G1820TE sits in a performance cluster where every chip delivers essentially the same user experience. The 4th percentile ranking reinforces that this is among the slowest CPUs in the benchmark database, with only 4% of all tested processors performing worse.
How It Compares
Intel Celeron 1020M – This mobile dual-core chip has an average score of 372, which is 0.1% behind the G1820TE. The two are functionally identical in performance, despite the 1020M being designed for laptops. Users upgrading from a 1020M to the G1820TE would see no meaningful change in compute speed.
AMD A8-5545M – Another mobile processor, the A8-5545M averages 372, just 0.1% ahead of the G1820TE. This AMD part includes a more capable integrated GPU, but in CPU-bound tasks the G1820TE is on par. The difference is far too small to affect real-world responsiveness.
Intel Core i7-660UM – A low-voltage mobile i7 from an older generation, the i7-660UM scores 375 on average, 0.9% higher than the G1820TE. Despite its "i7" branding, the 660UM was a low-power part, and its performance is essentially equivalent to the Celeron. The G1820TE's newer architecture does not translate into a measurable advantage here.
AMD Phenom II X2 B57 – A desktop dual-core from AMD, the B57 averages 368, which is 1% above the G1820TE. This is the largest delta among the rivals, but still within the margin of error for such low scores. The G1820TE trails slightly, but no user would notice the difference in typical workloads.
Power and Thermals
The G1820TE has a TDP of 54 W, which is modest for a desktop processor. This rating, combined with the absence of a boost clock, means the chip draws a steady, predictable amount of power under load. The 22 nm process and 1.4 billion transistors on a 177 mm² die contribute to efficient operation. A basic air cooler — even a low-profile or stock unit — is sufficient to keep the processor within safe temperatures, as the thermal load is low. The 54 W TDP also makes the chip suitable for small-form-factor builds or systems where cooling is limited. There is no need for liquid cooling or large tower coolers; the data indicates a simple, passive or low-speed fan solution would be adequate.

Who Should Consider It
Given its benchmark scores, the G1820TE is only suitable for the lightest computing tasks. The Cinebench R23 multi-core score of 867 and Geekbench multi-core of 707 indicate that it can handle basic office applications, web browsing, and document editing without significant lag, provided the software is not too demanding. However, any workload that requires sustained multi-core performance — such as video encoding, 3D rendering, or modern gaming — will be severely constrained. The single-core scores of 122 in R23 and 407 in Geekbench are too low for smooth gameplay or responsive creative tools. This processor is best suited for a secondary PC, a home server running simple services, or a dedicated machine for word processing and email. It is not a gaming CPU, nor is it a content-creation CPU; the data clearly shows it sits at the bottom of the performance spectrum.
Platform and Compatibility
The G1820TE is built for the Intel Socket 1150 platform, which supports DDR3 memory in a dual-channel layout. It provides PCIe Gen 3 connectivity, allowing for compatible expansion cards. The integrated Intel HD (Haswell) graphics eliminate the need for a discrete GPU in basic setups. Because the socket is shared with other Haswell-generation desktop processors, users have a potential upgrade path within the same platform, though the G1820TE's low performance means any upgrade would be a significant step up. The processor is still listed as "Active" in production, and its 22 nm process node and 1.4 billion transistors are typical of the Haswell generation. The lack of ECC memory support limits its use in error-sensitive server environments, but for a home or office machine, the platform is straightforward and compatible with common DDR3 modules.
Single-Thread vs Multi-Thread Behavior
The G1820TE's single-thread and multi-thread scores reveal a chip that is uniformly weak. In Cinebench R23, the multi-core score of 867 is about 7.1 times the single-core score of 122 — a ratio that seems high, but only because the single-core number is so low. The Geekbench results are more indicative: multi-core 707 versus single-core 407 gives a ratio of 1.74, close to the theoretical 2.0 for a dual-core without hyper-threading. This suggests the processor scales reasonably with additional cores, but the absolute performance per core is minimal. In real workloads, this means that while adding a second core helps, the entire chip is still far below what modern software expects. The single-core performance is particularly limiting for tasks that rely on one thread, such as older games or some office applications, where the G1820TE will feel sluggish. The multi-core advantage, while present, does not rescue the overall experience because even the best-case multi-core scores are very low. Users should expect consistent, but very low, performance across all types of workloads.
