AMD Radeon RX Vega M GH vs Intel Arc A370M Comparison

AMD Radeon RX Vega M GH and Intel Arc A370M are near-perfect statistical twins in aggregate benchmarks, yet they achieve parity through opposite performance profiles. The AMD part wins the Vulkan workload decisively, while the Intel part takes the OpenCL workload by a similar margin. Both GPUs sit at the 74th percentile among all tested graphics processors, with average scores of 29197 and 29175 respectively — a difference of just 0.1%. For a system builder choosing between these two, the decision hinges entirely on which API and workload pattern dominates the target use case, not on overall capability.

Where Each One Wins

The AMD Radeon RX Vega M GH is the clear choice for Vulkan-based applications. In the geekbench_vulkan test, it scores 31268 against the Intel Arc A370M's 28673, a 9.1% advantage. This is a substantial lead in a modern, low-level graphics API that is increasingly common in games and compute workloads. If your software stack prioritizes Vulkan, the AMD part offers a measurable performance cushion that the Intel GPU cannot match.

The Intel Arc A370M takes the crown in OpenCL workloads. It scores 29676 in geekbench_opencl, while the AMD Radeon RX Vega M GH trails at 27125 — an 8.6% deficit for AMD. OpenCL remains a staple for general-purpose GPU compute in content creation, scientific simulation, and legacy applications. For anyone running OpenCL-centric tasks, the Intel part delivers a tangible advantage that makes it the more practical pick despite the overall benchmark parity.

The split is clean: Vulkan favors AMD, OpenCL favors Intel. Each GPU wins exactly one of the two head-to-head tests. Neither part dominates the other across the board, so the workload mix is the only rational deciding factor. If you cannot predict your primary API, the data offers no tiebreaker — both sit at the same 74th percentile, and their average scores are within 0.1% of each other, which is effectively noise.

Architecture Differences

These two GPUs represent fundamentally different design philosophies and manufacturing approaches. The AMD Radeon RX Vega M GH uses the Polaris 22 chip built on GCN 4.0 architecture, fabricated on a 14 nm process at GlobalFoundries. It packs 5,000 million transistors into a 208 mm² die, yielding a transistor density of 24.0 million per square millimeter. This is an integrated graphics processor (IGP) with a 100 W thermal design power, reflecting its older, less efficient process node.

The Intel Arc A370M uses the DG2-128 chip with Xe-HPG architecture, built on a 6 nm process at TSMC. It contains 7,200 million transistors in a smaller 157 mm² die, achieving a much higher density of 45.9 million per square millimeter. This is a mobile part with a 35 W TDP, making it significantly more power-efficient per transistor. The Intel GPU also uses a PCIe 4.0 x8 bus interface, while the AMD part is limited to an IGP bus interface.

Memory architectures diverge sharply. The AMD GPU uses 4 GB of HBM2 with a 1024-bit bus, delivering 204.8 GB/s of bandwidth. The Intel GPU uses 4 GB of GDDR6 with a 64-bit bus, providing only 112.0 GB/s. The AMD part has more than 80% higher memory bandwidth, which could benefit certain bandwidth-sensitive workloads, though the benchmark results show this does not translate into universal superiority.

Compute unit configurations also differ. The AMD GPU has 1536 shading units, 96 texture mapping units (TMUs), and 64 render output units (ROPs). The Intel GPU has fewer of each: 1024 shading units, 64 TMUs, and 32 ROPs. However, the Intel part compensates with higher clock speeds — a 1550 MHz base and 2050 MHz boost, versus AMD's 1063 MHz base and 1190 MHz boost. The Intel GPU also includes 8 ray tracing cores, which the AMD part lacks entirely, and supports DirectX 12 Ultimate (12_2) versus AMD's DirectX 12 (12_0).

Head-to-Head Benchmarks

The geekbench_opencl test shows the Intel Arc A370M winning with a score of 29676 against AMD's 27125. This 8.6% margin is significant and consistent with the Intel part's higher raw compute throughput — it delivers 4.198 TFLOPS FP32 versus AMD's 3.656 TFLOPS. The Intel GPU's texture rate of 131.2 GTexel/s also exceeds AMD's 114.2 GTexel/s, indicating stronger texture-heavy compute performance. Even though the AMD GPU has a higher pixel rate (76.16 GPixel/s versus 65.60 GPixel/s), the OpenCL workload appears to favor the Intel architecture's superior clock speed and FP32 output.

The geekbench_vulkan test flips the result. The AMD Radeon RX Vega M GH scores 31268, beating the Intel Arc A370M's 28673 by 9.1%. This is a remarkable turnaround given the AMD GPU's lower FP32 throughput. The likely explanation lies in the AMD part's massive memory bandwidth advantage — 204.8 GB/s versus 112.0 GB/s. Vulkan workloads often stress memory access patterns, and the AMD GPU's 1024-bit HBM2 interface provides nearly double the bandwidth of Intel's 64-bit GDDR6 setup. This bandwidth headroom appears to override the clock speed deficit in this specific API.

The FP16 results further differentiate the two. The Intel GPU delivers 8.397 TFLOPS FP16 (2:1 ratio), more than double its FP32 output. The AMD GPU delivers only 3.656 TFLOPS FP16 (1:1 ratio), meaning it offers no half-precision acceleration. For any workload using FP16 arithmetic — common in machine learning inference and some rendering pipelines — the Intel part has a clear architectural advantage that the current benchmarks do not fully capture.

The Verdict

The data presents a genuine paradox: two GPUs with nearly identical aggregate scores, yet opposite strengths. The AMD Radeon RX Vega M GH is the pick for Vulkan-centric systems. Its 9.1% lead in geekbench_vulkan is substantial, and its 204.8 GB/s memory bandwidth provides headroom that the Intel part cannot match in memory-heavy scenarios. The AMD GPU's higher pixel rate (76.16 GPixel/s) also suggests better fill-rate-bound performance, which matters for certain rasterization tasks.

The Intel Arc A370M is the pick for OpenCL-heavy workloads and any application that leverages FP16 math or ray tracing. Its 8.6% OpenCL advantage is equally significant, and its 8.397 TFLOPS FP16 output is more than double the AMD part's capability. The inclusion of 8 ray tracing cores gives it a feature that the AMD GPU simply lacks. The Intel part also consumes only 35 W versus AMD's 100 W, making it dramatically more suitable for thin-and-light mobile designs.

For a neutral recommendation: if your workload is unknown or mixed, the choice is a coin flip — both sit at the 74th percentile, and the 0.1% average score difference is statistically negligible. If your workload is known, the decision is obvious. Vulkan users should take the AMD Radeon RX Vega M GH without hesitation. OpenCL users, FP16 compute developers, or anyone wanting ray tracing should take the Intel Arc A370M. The Intel part's newer architecture, higher clocks, and lower power draw give it a forward-looking edge, but the AMD part's memory bandwidth and Vulkan performance remain competitive even against a much newer design.
