AMD Radeon R5 M430 vs Intel UHD Graphics P630 Comparison

Intel UHD Graphics P630 and AMD Radeon R5 M430 are both end-of-life integrated graphics solutions, but they deliver distinctly different performance profiles depending on the API used. The data shows a split decision: AMD wins the OpenCL compute test by a razor-thin margin, while Intel dominates the Vulkan graphics workload by a substantial 15.2%. Overall, the Intel part holds a higher average benchmark score of 5370 versus 5018 for AMD, placing it at the 31st percentile of all GPUs compared to AMD's 30th.

Head-to-Head Benchmarks

The two GPUs trade victories across the two available benchmark tests, with the margins telling very different stories. In Geekbench OpenCL, the AMD Radeon R5 M430 scores 5152 against Intel's 5111, a delta of just -0.8% from Intel's perspective. This is effectively a statistical tie, with the AMD part edging ahead by only 41 points. The Intel UHD Graphics P630's nearest rivals include the AMD Radeon R7 M445 at 5358 (0.2% higher) and the NVIDIA GeForce 930A at 5317 (1% higher), showing that both contenders sit in a tightly packed performance band for compute workloads.

The Vulkan result is where the Intel part separates itself decisively. Intel UHD Graphics P630 scores 5628, while the AMD Radeon R5 M430 manages only 4884. That is a 15.2% advantage for Intel, a margin large enough to be clearly noticeable in real-world graphics applications. Intel's Vulkan score even exceeds its own OpenCL result by over 500 points, suggesting the architecture handles modern graphics APIs particularly well. In contrast, AMD's Vulkan score is actually lower than its OpenCL score by 268 points, indicating weaker scaling with this API generation.

Looking at the average benchmark scores, Intel's 5370 places it slightly above the AMD Radeon R7 M445 (5358) and the NVIDIA GeForce 840M (5322), while AMD's 5018 sits just below the AMD FirePro W4170M (5034) and above the AMD Radeon R7 Graphics (4998). The 352-point gap in average score between the two reviewed parts corresponds to a 7% difference, which is consistent with Intel's higher percentile ranking. The data indicates that Intel's wins are concentrated in graphics-heavy workloads, while AMD's single victory is too narrow to shift the overall balance.

Architecture Differences

The two GPUs come from fundamentally different architectural lineages. Intel's UHD Graphics P630 is built on the Generation 9.5 architecture using the Comet Lake GT2 chip, manufactured on a 14 nm+++ process at Intel's own foundry. It belongs to the HD Graphics-W (Comet Lake) generation. In contrast, the AMD Radeon R5 M430 uses the GCN 1.0 architecture with the Jet chip, fabricated on a 28 nm process at TSMC, and traces its lineage to the Gem System (R5 M400) generation with a predecessor named Solar System and successor Polaris Mobile.

The memory architecture diverges sharply. Intel's solution uses System Shared memory, where the GPU borrows from the main system RAM, making bandwidth inherently system-dependent. AMD's part has dedicated 4 GB of DDR3 memory on a 64-bit bus, delivering a fixed 16.00 GB/s bandwidth. This dedicated memory gives AMD a consistent memory performance profile, while Intel's approach scales with the host system's memory configuration. The clock speeds also differ: Intel runs at a base of 350 MHz boosting to 1200 MHz, while AMD runs higher at a base of 780 MHz boosting to 855 MHz.

Shader resources are organized differently between the two. The Intel part has 192 shading units, 24 texture mapping units, and only 3 ROPs, while the AMD part packs 320 shading units, 20 TMUs, and 8 ROPs. Despite having fewer shaders, Intel achieves a texture rate of 28.80 GTexel/s, which is substantially higher than AMD's 17.10 GTexel/s. Conversely, AMD's pixel rate of 6.840 GPixel/s nearly doubles Intel's 3.600 GPixel/s, reflecting the ROP count disparity. In raw FP32 compute, AMD leads with 547.2 GFLOPS, while Intel delivers 460.8 GFLOPS, but Intel provides FP16 support at 921.6 GFLOPS (2:1 ratio) while AMD lists no FP16 capability.

Specification Differences

The specification table reveals clear contrasts across nearly every major category. The manufacturing process differs significantly: Intel uses 14 nm+++ while AMD uses 28 nm, with AMD's transistor density listed at 12.3M / mm². Clock speeds show Intel boosting to 1200 MHz from a 350 MHz base, while AMD runs at 780 MHz base and 855 MHz boost. Memory configurations are entirely different: Intel uses System Shared memory with dependent bandwidth, while AMD uses 4 GB of DDR3 with a 64-bit bus and 16.00 GB/s bandwidth.

Core counts differ in every category: Intel has 192 shading units, 24 TMUs, and 3 ROPs, while AMD has 320 shading units, 20 TMUs, and 8 ROPs. The AMD part has a higher pixel rate at 6.840 GPixel/s versus Intel's 3.600 GPixel/s, but Intel wins texture rate at 28.80 GTexel/s versus AMD's 17.10 GTexel/s. FP32 compute favors AMD at 547.2 GFLOPS, while Intel offers FP16 at 921.6 GFLOPS where AMD has none. The bus interface also differs: Intel uses Ring Bus while AMD uses PCIe 3.0 x8.

API support shows Intel supporting DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.3, while AMD supports DirectX 12 (11_1), OpenGL 4.6, and Vulkan 1.2.170. Display outputs are motherboard dependent for Intel and portable device dependent for AMD, reflecting their different target platforms. Thermal design power is listed only for Intel at 15 W, with AMD's TDP not provided in the data. The release dates also differ, with Intel launching on May 12, 2020, while AMD's release date is not listed.

Where Each One Wins

The Intel UHD Graphics P630 wins decisively in Vulkan-based workloads, where its 15.2% advantage over the AMD part is the single largest margin in any comparison. This makes it the stronger choice for applications that leverage Vulkan for rendering, particularly modern games and graphics software that utilize this API. Intel's higher average benchmark score of 5370 and superior texture rate of 28.80 GTexel/s also position it well for texture-heavy tasks. Its FP16 support at 921.6 GFLOPS could benefit compute workloads that use reduced precision, and its 14 nm+++ process suggests better power efficiency per unit of work, though TDP is only listed for Intel.

The AMD Radeon R5 M430 wins the OpenCL compute test, albeit narrowly, and offers several advantages in specific hardware capabilities. Its dedicated 4 GB of DDR3 memory provides predictable bandwidth of 16.00 GB/s, which is preferable in scenarios where system memory is slow or shared with other components. The higher pixel rate of 6.840 GPixel/s and 8 ROPs make AMD more capable in fill-rate-bound operations, such as pixel-heavy post-processing effects. The 320 shading units provide more parallel compute lanes, which helps explain its OpenCL edge, and its 547.2 GFLOPS FP32 throughput is higher than Intel's.

For legacy applications or those optimized for GCN architecture, AMD's older but established design may offer better compatibility. The AMD part also holds a slight advantage in the OpenCL test, making it marginally better for compute tasks that use that API. However, the narrowness of that win (-0.8%) means it is unlikely to be perceptible in practice. The data suggests AMD's wins are concentrated in traditional compute workloads with dedicated memory, while Intel's strengths lie in modern graphics APIs and texture throughput.

The Verdict

From the benchmark data, the Intel UHD Graphics P630 is the stronger overall performer, with a higher average score of 5370, a better percentile ranking at 31st, and a decisive 15.2% Vulkan advantage. The AMD Radeon R5 M430's sole win in OpenCL is a marginal 0.8% edge that falls within typical run-to-run variance. Any user choosing between these two for graphics-intensive tasks should favor Intel based on the Vulkan results alone, as that API is increasingly relevant for modern software.

The AMD Radeon R5 M430 remains a viable option specifically for users who rely on OpenCL compute workloads and benefit from its dedicated 4 GB memory pool. Its higher FP32 throughput of 547.2 GFLOPS and superior pixel rate could also be factors in niche scenarios. However, the data shows AMD's overall position is weaker: a 30th percentile ranking, lower average score, and a Vulkan deficit that cannot be ignored.

For most use cases, the Intel UHD Graphics P630 is the recommended choice. It delivers better graphics API performance, higher texture throughput, and a more modern process node. The AMD part only makes sense if the specific application is OpenCL-bound and the dedicated memory bandwidth is a requirement. Otherwise, the benchmark evidence points clearly to Intel as the superior solution across the broader range of workloads.
