AMD Radeon R9 M375X vs Intel Arc A380 Comparison

The Intel Arc A380 and AMD Radeon R9 M375X represent two very different eras of graphics hardware, and the benchmark data reflects a decisive generational shift. The Arc A380, built on Intel's modern Xe-HPG architecture, delivers a level of compute and API performance that the older GCN-based R9 M375X cannot approach. In the available head-to-head tests, the Intel part wins every single benchmark, often by staggering margins, making it the clear choice for any workload that leverages modern APIs or raw compute throughput.

Where Each One Wins

Intel Arc A380: The unequivocal winner in compute and modern API workloads. The data shows a complete sweep for the Arc A380 across all shared benchmark tests. In Geekbench OpenCL, the Arc A380 scores 38,224 against the R9 M375X's 8,273, a gap of 362%. This indicates a massive advantage in general-purpose compute tasks, which is critical for content creation, video encoding, and any application that offloads parallel processing to the GPU. Similarly, in Geekbench Vulkan, the Arc A380's score of 36,736 dwarfs the R9 M375X's 8,377, a 338.5% lead. This suggests the Arc A380 is vastly more capable in modern game engines and applications that utilize the Vulkan API. The Arc A380 also holds a 44th percentile ranking among all GPUs, slightly ahead of the R9 M375X's 43rd, and its average benchmark score of 8,558 is higher than the R9 M375X's 8,325.

AMD Radeon R9 M375X: No winning scenarios in the available data. Based on the provided benchmark results, there are no test categories where the R9 M375X outperforms the Arc A380. Its wins total is zero. While it does offer its own set of specifications, the performance data clearly indicates it is outclassed. The R9 M375X's average score of 8,325 places it just 0.7% behind the NVIDIA Quadro K1200 (8,265) and 1.2% behind the GeForce GTX 675MX (8,427), showing it was a mid-range part in its own generation. However, against the Arc A380, it has no competitive advantage in the measured benchmarks.

Head-to-Head Benchmarks

The head-to-head data is stark, showing the Intel Arc A380 dominating in both available tests. The largest win for the Arc A380 comes in the Geekbench OpenCL test. Here, the Intel part scores 38,224, while the AMD Radeon R9 M375X scores just 8,273. This results in a delta of 362%, meaning the Arc A380 is over three and a half times faster in this compute-heavy workload. This massive difference highlights the architectural leap between the two GPUs, likely stemming from the Arc A380's significantly higher shader count and modern design.

The second and final head-to-head test, Geekbench Vulkan, shows a similar outcome. The Intel Arc A380 scores 36,736, while the AMD Radeon R9 M375X scores 8,377. This gives the Arc A380 a 338.5% advantage. This result is particularly telling for gaming, as Vulkan is a low-overhead API used in many modern titles. The Arc A380's ability to nearly quadruple the R9 M375X's performance in this test suggests that it will provide a far smoother experience in games that support Vulkan, with higher frame rates and better overall responsiveness. In both tests, the margin is so large that it transcends generational differences and indicates a complete performance class separation.

Specification Differences

The specification sheets for these two GPUs reveal fundamental differences in their design and intended use cases. The memory subsystem is a key divider. The Intel Arc A380 comes with 6 GB of GDDR6 memory on a 96-bit bus, delivering 186.0 GB/s of bandwidth. In contrast, the AMD Radeon R9 M375X has only 2 GB of GDDR5 memory on a 128-bit bus, resulting in 72.00 GB/s of bandwidth. The Arc A380 has three times the memory capacity and over 2.5 times the bandwidth, which is crucial for modern game textures and high-resolution assets.

The compute resources also differ greatly. The Arc A380 features 1024 shading units, 64 TMUs, and 32 ROPs. The R9 M375X is configured with 640 shading units, 40 TMUs, and 16 ROPs. This gives the Intel part 60% more shading units and double the ROPs, contributing to its superior pixel and texture processing rates. The clock speeds are also distinct, with the Arc A380 boosting to 2050 MHz compared to the R9 M375X's 1015 MHz boost clock. This higher clock speed, combined with the larger shader array, allows the Arc A380 to achieve 4.198 TFLOPS of FP32 performance versus 1,299.2 GFLOPS for the AMD part. The bus interface is another differentiating factor, with the Arc A380 using PCIe 4.0 x8 while the R9 M375X uses the older PCIe 3.0 x16 standard.

Architecture Differences

The architectural divide between these two GPUs is as wide as the performance gap. The Intel Arc A380 is built on the Xe-HPG architecture, specifically the DG2-128 chip, and is part of the Alchemist generation. It's fabricated on a 6 nm process at TSMC, packing 7,200 million transistors into a 157 mm² die. This results in a high transistor density of 45.9M per mm². The architecture natively supports hardware ray tracing via 8 dedicated RT cores, a feature entirely absent from the older AMD part. It also supports a modern feature set, including DirectX 12 Ultimate (12_2) and Vulkan 1.4, and features DisplayPort 2.0 outputs.

In contrast, the AMD Radeon R9 M375X is based on the GCN 1.0 architecture and uses the Tropo chip. It belongs to the Gem System generation and is manufactured on a much older 28 nm process at TSMC. This older process results in a lower transistor density of 12.2M per mm², with 1,500 million transistors on a 123 mm² die. The GCN 1.0 architecture lacks any dedicated ray tracing cores and supports an older feature set, including DirectX 12 (11_1) and Vulkan 1.2.170. While it does support OpenGL 4.6, its overall feature set is dated. The Intel Arc A380 also supports FP16 compute at a 2:1 ratio, offering 8.397 TFLOPS, while the AMD part has no listed FP16 support. These architectural differences explain why the Arc A380 achieves such high scores in modern compute and graphics APIs, as it was designed for the current generation of software, whereas the R9 M375X is a legacy product.
