Introduction

The MediaTek Helio G100, Dimensity 6400 and Dimensity 6080 are three 6nm smartphone processors designed for affordable and mid-range devices. They share an eight-core CPU configuration with two Cortex-A76 performance cores and six Cortex-A55 efficiency cores. All three also use the Mali-G57 MP2 GPU and LPDDR4X memory.

However, these processors are not identical. The Helio G100 is a 4G chipset, while both Dimensity models support 5G connectivity. The Dimensity 6400 has the highest CPU clock speed, the Dimensity 6080 supports the largest maximum RAM capacity, and the Helio G100 offers a 200MP maximum camera-resolution specification.

NanoReview gives the Dimensity 6400 an overall score of 32/100, while the Helio G100 and Dimensity 6080 both receive 31/100. The Dimensity 6400 also leads the CPU rating, while all three share the same gaming and battery ratings.

Benchmark results reveal a close competition. The Dimensity 6400 leads AnTuTu 11 and Geekbench 6 CPU performance, while the Helio G100 leads Geekbench 6 GPU Compute and PCMark 3.0. The Dimensity 6080 has the highest listed 3DMark Steel Nomad Light score.

This comparison uses NanoReview’s published specifications and benchmark results to explain the differences in processing performance, graphics, gaming, camera support, memory, connectivity and everyday use.

CPU Architecture and Processing Performance

The Dimensity 6400 has the highest listed CPU clock speed in this comparison. It features two Cortex-A76 performance cores running at 2.5GHz and six Cortex-A55 efficiency cores at 2.0GHz.

The Dimensity 6080 uses the same CPU core types but operates its performance cores at 2.4GHz. The Helio G100 has the lowest performance-core frequency at 2.2GHz. All three processors use the same 2.0GHz frequency for their six efficiency cores.

This gives the Dimensity 6400 a frequency advantage in CPU-heavy workloads. Its higher performance-core clock can help with tasks that depend on fast individual-core execution, although actual performance also depends on software, memory behaviour and thermal management.

NanoReview assigns the Dimensity 6400 a CPU performance rating of 27, while the Helio G100 and Dimensity 6080 both receive 26.

The Geekbench 6 results support the Dimensity 6400’s lead. It records the highest single-core and multi-core scores among these processors. The G100 and Dimensity 6080 remain close competitors, particularly in multi-core performance.

For everyday tasks such as application launching, browsing, messaging and multitasking, all three offer a similar general hardware foundation. The Dimensity 6400 has the strongest listed CPU specifications, but the smartphone’s RAM, storage and software optimisation also influence the final experience.

GPU and Gaming Performance

All three processors use the Mali-G57 MP2 graphics processor, based on ARM’s Valhall first-generation GPU architecture. Their main difference is the listed GPU frequency.

The Dimensity 6400 operates at 1072MHz, narrowly ahead of the Dimensity 6080 at 1068MHz. The Helio G100 runs its GPU at 1000MHz.

Their theoretical graphics performance is also close. NanoReview lists 137.2 GFLOPS for the Dimensity 6400, 136.7 GFLOPS for the Dimensity 6080 and 128 GFLOPS for the Helio G100.

These figures give the Dimensity 6400 a small specification advantage. However, a GPU’s real-world gaming performance depends on more than its clock speed or theoretical throughput. Driver optimisation, game compatibility, memory behaviour, cooling and device-level power limits also matter.

NanoReview gives all three processors a gaming performance rating of 6. This is an exact tie in its rating system.

The Steel Nomad Light results are also close: the Dimensity 6080 scores 150, the Dimensity 6400 scores 148 and the Helio G100 scores 146. The Dimensity 6080 leads this particular benchmark, but the small differences do not establish a major real-world gaming advantage.

For casual gaming, all three have similar listed graphics hardware. The Dimensity 6400 and 6080 offer slightly higher GPU frequencies, while the G100 remains competitive. None should be treated as a dedicated flagship gaming processor.

Benchmark Comparison: AnTuTu 11, Geekbench 6 and PCMark

Benchmark results help explain the performance differences between these chipsets. AnTuTu measures several parts of a smartphone platform, Geekbench focuses on CPU and compute workloads, 3DMark evaluates graphics, and PCMark measures everyday productivity tasks.

Source: NanoReview. Sample counts differ between processors and tests; benchmark scores should be interpreted as published database results rather than controlled tests using identical smartphones.

AnTuTu 11 Performance

The Dimensity 6400 leads AnTuTu 11 with 581,041 points. The Helio G100 follows with 575,630 points, while the Dimensity 6080 records 573,460 points.

The difference between the Dimensity 6400 and G100 is only 5,411 points. The Dimensity 6080 is also close, trailing the G100 by 2,170 points.

These results show that the three processors offer very similar overall AnTuTu 11 performance. The Dimensity 6400 is the winner, but its advantage is relatively small.

The AnTuTu component scores provide additional context. The Dimensity 6400 leads the CPU and GPU components, while the G100 records the highest memory component score. The Dimensity 6080 has the highest UX component score among the three.

This demonstrates that overall AnTuTu performance is influenced by several parts of the chipset, not just CPU frequency.

Geekbench 6 CPU Performance

The Dimensity 6400 also leads both Geekbench 6 CPU tests.

In single-core performance, it scores 803 points. The Dimensity 6080 follows with 750, while the Helio G100 records 727.

In multi-core performance, the Dimensity 6400 achieves 2,047 points, the Dimensity 6080 scores 2,020 and the G100 records 2,014.

The multi-core results are particularly close. The G100 trails the Dimensity 6400 by only 33 points, while the Dimensity 6080 is 27 points behind.

These results make the Dimensity 6400 the Geekbench 6 CPU winner. Its higher 2.5GHz performance-core frequency is consistent with its lead, especially in single-core performance.

NanoReview lists 26 Geekbench CPU samples for the G100, 8 for the Dimensity 6400 and 11 for the Dimensity 6080. The Dimensity 6400’s lead is supported by the listed results, but its smaller sample count should be considered when evaluating how representative the figures are.

GPU Compute Performance

The Geekbench 6 GPU Compute results show a different ranking.

The Helio G100 scores 1,467 points, ahead of the Dimensity 6400 at 1,427 and the Dimensity 6080 at 1,407.

All three use OpenCL in the listed GPU Compute test, making these results more directly comparable than tests using different APIs. The G100 leads this particular benchmark despite having the lowest listed GPU frequency and theoretical FLOPS.

This is a useful reminder that theoretical GPU specifications do not always predict benchmark results. Architecture implementation, drivers and device-level conditions can affect measured performance.

NanoReview lists 19 GPU Compute samples for the G100, 7 for the Dimensity 6400 and 11 for the Dimensity 6080. The G100 has the largest sample count in this test.

3DMark Steel Nomad Light

The Dimensity 6080 records the highest Steel Nomad Light result at 150 points. The Dimensity 6400 follows at 148, while the Helio G100 scores 146.

The difference between the highest and lowest results is only four points. This suggests that the three processors deliver closely matched performance in this particular graphics test.

The G100 has a listed stability result of 97%, while the Dimensity 6080 records 98%. NanoReview does not list a stability figure for the Dimensity 6400 on the page. Therefore, a complete three-way stability comparison is not available.

PCMark 3.0: Everyday Workloads

The Dimensity 6400 leads PCMark 3.0 with 10,960 points. The Helio G100 follows with 10,665, while the Dimensity 6080 scores 10,262.

PCMark evaluates everyday workloads such as web browsing, writing, photo editing, video editing and data manipulation. It provides a different perspective from CPU-only or graphics-focused tests.

The Dimensity 6400 has the highest overall result, but NanoReview lists only three tested phone models for this processor. The G100 has 14 tested models, while the Dimensity 6080 has five. The limited Dimensity 6400 device sample means its PCMark lead should be interpreted carefully.

RAM, Memory Bandwidth and Storage

All three processors support LPDDR4X memory and UFS 2.2 storage. Their maximum memory bandwidth is also very similar.

The Helio G100 and Dimensity 6400 support up to 12GB of RAM. The Dimensity 6080 has the highest listed maximum capacity at 16GB.

This gives the Dimensity 6080 a specification advantage for maximum memory capacity. However, the actual RAM configuration depends on the smartphone manufacturer, and not every phone using this processor will include 16GB.

The G100 lists 17Gb/s of maximum memory bandwidth, while both Dimensity processors list 17.07Gb/s. The difference is extremely small.

All three support UFS 2.2 storage, so there is no storage-standard winner in this comparison. Actual storage speed depends on the hardware selected by the manufacturer.

Display, Camera and Multimedia Capabilities

All three processors support a maximum display resolution of 2520 × 1080 pixels. They also share 2K video capture and playback at 30FPS.

Camera support is where the Helio G100 has a clear specification advantage. It supports a maximum single-camera resolution of 200MP, compared with 108MP for both Dimensity processors.

This makes the G100 the leader in maximum listed camera resolution. However, a higher megapixel limit does not guarantee better photographs. Sensor quality, lens design, image processing, autofocus and camera software all influence the final image.

The Dimensity 6400 and Dimensity 6080 still support high-resolution camera configurations. Their 108MP limits are sufficient for many mid-range smartphone designs.

For buyers comparing camera specifications, the G100 offers the highest maximum resolution on paper. The final camera experience should still be judged by the actual smartphone’s camera hardware and image processing.

Connectivity: 4G vs 5G

Connectivity is the most important practical difference between these three processors.

The Helio G100 is a 4G-only chipset. It supports LTE Cat. 13, with listed download speeds of up to 650Mbps and upload speeds of up to 150Mbps. It does not support 5G.

The Dimensity 6400 and Dimensity 6080 both support 5G connectivity. The Dimensity 6400 lists maximum download speeds of up to 3300Mbps, while the Dimensity 6080 lists up to 2770Mbps.

The Dimensity 6080 also lists LTE Cat. 18 support, with maximum 4G download speeds of up to 2770Mbps and upload speeds of up to 1250Mbps. The Dimensity 6400’s page provides its 5G maximum download speed but does not list an equivalent LTE category in the same specification section.

All three support Wi-Fi 5. Bluetooth versions differ: the G100 and Dimensity 6400 support Bluetooth 5.4, while the Dimensity 6080 uses Bluetooth 5.1.

For users who need 5G connectivity, the Dimensity 6400 and Dimensity 6080 are the only suitable options in this comparison. The G100 remains a capable 4G chipset, but its lack of 5G is a major limitation for buyers who want a 5G smartphone.

AI Processing and Battery Ratings

NanoReview lists a neural processing unit (NPU) for all three processors. This means each chipset includes dedicated hardware for supported AI and machine-learning workloads.

However, an NPU does not automatically guarantee support for every modern AI feature. Actual capabilities depend on the processor implementation, compatible software and smartphone manufacturer’s integration.

For battery life, all three processors receive the same NanoReview rating of 87. This is an exact three-way tie.

The shared 6nm manufacturing process and similar CPU and GPU architecture provide a common hardware foundation, but they do not guarantee identical battery endurance. Battery capacity, display brightness, mobile signal, software optimisation and usage patterns have a major impact on real-world battery life.

Which Processor Should You Choose?

The MediaTek Helio G100 is a strong option for users who do not need 5G but want a capable 4G chipset with high camera-resolution support. It supports up to 200MP cameras, Bluetooth 5.4 and up to 12GB RAM. It also leads Geekbench 6 GPU Compute and PCMark 3.0 in the listed results. Its biggest limitation is the absence of 5G connectivity.

The MediaTek Dimensity 6400 is the strongest overall processor in this comparison according to NanoReview. It has the highest overall score, CPU rating, AnTuTu 11 result and Geekbench 6 CPU scores. It also supports 5G, Bluetooth 5.4 and up to 12GB RAM. Its main advantage is its higher CPU frequency, while its benchmark sample counts remain relatively small in some tests.

The MediaTek Dimensity 6080 remains a competitive 5G alternative. It has a 2.4GHz Cortex-A76 performance core configuration, supports up to 16GB RAM and records the highest Steel Nomad Light result. Its overall score matches the Helio G100, although its CPU rating is lower than the Dimensity 6400.

Final Verdict

The Dimensity 6400, Helio G100 and Dimensity 6080 are closely matched in several benchmarks, but they serve different priorities.

The Dimensity 6400 is the overall winner according to NanoReview, with a score of 32/100. The Helio G100 and Dimensity 6080 share second place with 31/100 each.

The Dimensity 6400 leads CPU performance and AnTuTu 11. The G100 offers the highest maximum camera-resolution support and GPU Compute result. The Dimensity 6080 leads the listed 3DMark Steel Nomad Light test and supports the highest maximum RAM capacity.
