AMD Radeon R5 M430 vs AMD Radeon R7 M440 Comparison

The AMD Radeon R7 M440 and AMD Radeon R5 M430 are both end-of-life integrated-class mobile GPUs from AMD’s Gem System (M400) generation, built on the same 28 nm TSMC process. The data shows a clear overall winner: the R7 M440 takes both available benchmark wins, but the margin is far more decisive in one workload than the other. The R7 M440’s average benchmark score is 5483, placing it in the 32nd percentile of all GPUs, while the R5 M430 averages 5018, sitting in the 30th percentile. This 9.3% gap in average score is driven almost entirely by a massive Vulkan advantage, whereas OpenCL performance is nearly identical.

Where Each One Wins

The R7 M440 wins on raw compute throughput and modern API efficiency. In the Geekbench Vulkan test, it scores 5751 against the R5 M430’s 4884, a commanding 17.8% lead. This is the single largest differentiator between the two parts and reflects the R7 M440’s newer GCN 3.0 architecture, which is better optimized for low-level, multi-threaded graphics workloads. The Vulkan score also puts the R7 M440 ahead of several of its nearest rivals: it beats the NVIDIA Quadro M4000 (5467) by 0.3% and the AMD Radeon 610M (5444) by 0.7%, while trailing the NVIDIA GeForce GTX 765M (5501) by only 0.3% and the NVIDIA GeForce MX130 (5508) by 0.5%.

The R5 M430, by contrast, does not win any benchmark outright. Its closest claim to a victory is in OpenCL, where it scores 5152 against the R7 M440’s 5214, a deficit of just 1.2%. In that test, the R5 M430 is effectively competitive, falling within the noise of its own rival set: it trails the AMD FirePro W4170M (5034) by 0.3% and the AMD Radeon R7 M340 (5063) by 0.9%, but beats the AMD Radeon R7 Graphics (4998) by 0.4% and the NVIDIA Quadro 4000 (4979) by 0.8%. The R5 M430’s strength, if any, lies in this narrow OpenCL band where architecture generation matters less and raw shader count dominates — and both chips share the same 320 shading units.

The Verdict

Pick the AMD Radeon R7 M440 if you need any degree of modern API performance. The 17.8% Vulkan lead is the deciding factor — it is not a marginal difference but a substantial one that will manifest in any Vulkan-based game or compute application. The R7 M440’s average score of 5483 also places it in a higher competitive tier: it is within 0.5% of the NVIDIA GeForce MX130 and GTX 765M, whereas the R5 M430’s 5018 average sits closer to older parts like the NVIDIA Quadro 4000 (4979) and the integrated AMD Radeon R7 Graphics (4998). For OpenCL-only workloads, the choice is nearly moot — the 1.2% delta is unlikely to be perceptible.

Pick the AMD Radeon R5 M430 only if the workload is exclusively OpenCL-based and the 1.2% performance difference is acceptable. The data shows no scenario where the R5 M430 wins outright, so its only justification is availability or system integration, not performance. Its lower 30th percentile ranking and the fact that it scores below its own nearest rival average (5018 vs. 5034 for the FirePro W4170M) indicate it is the weaker part in the broader market. There is no benchmark result that favors the R5 M430, making the verdict straightforward: the R7 M440 is the superior GPU in every measured category, with the gap ranging from negligible (OpenCL) to decisive (Vulkan).

Head-to-Head Benchmarks

The Geekbench OpenCL test is the closer of the two. The R7 M440 scores 5214, while the R5 M430 scores 5152, yielding a delta of just 1.2% in favor of the R7 M440. This result is consistent with the hardware: both GPUs have identical 320 shading units, 20 texture mapping units, and 8 ROPs, and both use a 64-bit DDR3 memory bus. The R7 M440’s slight edge comes from its higher pixel rate (7.128 GPixel/s vs. 6.840 GPixel/s) and texture rate (17.82 GTexel/s vs. 17.10 GTexel/s), which are direct consequences of its higher effective clock behavior. In OpenCL, the R7 M440 also outperforms the AMD Radeon 610M (5444) by 0.7%, but trails the NVIDIA Quadro M4000 (5467) by 0.3%.

The Geekbench Vulkan test is where the R7 M440 separates itself. Its score of 5751 crushes the R5 M430’s 4884, a 17.8% advantage. This is not a small architectural tweak — it reflects the R7 M440’s GCN 3.0 design versus the R5 M430’s GCN 1.0. The newer architecture supports DirectX 12 (12_0) whereas the R5 M430 only reaches DirectX 12 (11_1), and that feature-level gap likely contributes to the Vulkan disparity. The R7 M440’s Vulkan score also places it above three of its four nearest rivals, including the NVIDIA Quadro M4000 (5467) and the AMD Radeon 610M (5444), while coming within 0.5% of the NVIDIA GeForce GTX 765M (5501) and MX130 (5508). The R5 M430, by contrast, scores far below its nearest rivals in Vulkan; its 4884 is 2.9% below the AMD FirePro W4170M’s 5034 and 3.0% below the AMD Radeon R7 M340’s 5063.

Architecture Differences

The two GPUs come from different GCN generations despite sharing the same 28 nm TSMC process. The R7 M440 uses the Meso chip with GCN 3.0 architecture, while the R5 M430 uses the Jet chip with GCN 1.0. This generation gap explains the Vulkan performance disparity: GCN 3.0 includes architectural refinements for lower-level API efficiency that GCN 1.0 lacks. The transistor counts differ substantially — the R7 M440 packs 1,550 million transistors on a 125 mm² die, versus 690 million on a 56 mm² die for the R5 M430. The transistor density is nearly identical (12.4M / mm² vs. 12.3M / mm²), confirming that the R7 M440’s larger die is used for additional logic, not just more of the same.

The R7 M440 also has a higher pixel rate (7.128 GPixel/s vs. 6.840 GPixel/s) and texture rate (17.82 GTexel/s vs. 17.10 GTexel/s). Both GPUs share the same core configuration of 320 shading units, 20 TMUs, and 8 ROPs, so these rate differences come from clock speeds rather than core counts. The R5 M430 has explicit base and boost clocks of 780 MHz and 855 MHz, respectively, while the R7 M440 lists no base or boost clock in the data — only its memory clock. The FP32 compute output reflects this: the R7 M440 delivers 570.2 GFLOPS versus 547.2 GFLOPS for the R5 M430, a 4.2% advantage. The R7 M440 also lists FP16 performance at 570.2 GFLOPS (1:1 ratio), while the R5 M430 has no FP16 figure.

Specification Differences

The most relevant specification gap is the memory clock. The R7 M440 runs its DDR3 memory at 900 MHz with 1800 Mbps effective, while the R5 M430 runs at 1000 MHz with 2 Gbps effective. Despite the higher clock on the R5 M430, the R7 M440 achieves a higher bandwidth figure of 14.40 GB/s versus 16.00 GB/s — wait, that is reversed: the R5 M430’s 2 Gbps effective translates to 16.00 GB/s, which is higher than the R7 M440’s 14.40 GB/s. Both use 4 GB of DDR3 on a 64-bit bus. The R5 M430’s memory advantage does not translate into benchmark wins, likely because the core clock and architecture differences dominate.

Both GPUs are integrated-class parts (IGP slot width) with portable-device-dependent display outputs and no power connectors or suggested PSU. They share the same PCIe 3.0 x8 bus interface. The R7 M440 was released on 2016-05-14, while the R5 M430 has no release date listed. Both are end-of-life, both succeed the Solar System generation, and both are succeeded by Polaris Mobile. The R7 M440’s DirectX 12 (12_0) support is a full feature level above the R5 M430’s DirectX 12 (11_1), which is the only API-level difference beyond the already-noted Vulkan performance. Neither GPU has a launch MSRP listed, so no pricing data is available.
