AMD Radeon Pro Duo vs Intel Arc A370M Comparison

AMD Radeon Pro Duo vs Intel Arc A370M: a comparison that spans two very different eras of GPU design. The data shows a clear winner in raw compute, but the architecture and intended use cases are worlds apart. The AMD Radeon Pro Duo leads in the single recorded OpenCL benchmark by a significant margin, while the Intel Arc A370M brings modern features and efficiency that the older card cannot match.

Where Each One Wins

The AMD Radeon Pro Duo is the undisputed champion of raw compute throughput in this matchup. Its Geekbench OpenCL score of 35,860 sits at the 80th percentile of all GPUs, a full 20.8% ahead of the Intel Arc A370M's score of 29,676. This makes it the clear choice for workloads that demand massive parallel processing power, such as professional rendering, scientific simulation, and complex data analysis. Its performance is closely matched with the NVIDIA Quadro GV100, which scores 35,520, a delta of only 1%, and the NVIDIA GeForce RTX 5070 Ti Mobile at 35,435, just 1.2% behind. It even edges out the NVIDIA T1000 and the AMD Radeon RX 5300M, which post 36,289 and 36,529 respectively, though by smaller margins of -1.2% and -1.8%. The Pro Duo is a brute-force compute specialist.

The Intel Arc A370M wins in every other category that matters for a modern, mobile GPU. While its OpenCL score is lower, it also has a Vulkan score of 28,673, a feature the Radeon Pro Duo lacks entirely in the database. It is a 35 W part, a stark contrast to the 350 W TDP of the AMD card, making it the obvious choice for thin-and-light laptops where power draw and heat dissipation are paramount. Its architecture is significantly newer, and it supports modern APIs like DirectX 12 Ultimate (12_2) and Vulkan 1.4, while the Pro Duo is limited to DirectX 12 (12_0) and Vulkan 1.2.170. For gaming, content creation on the go, or any workload that benefits from hardware ray tracing, the Arc A370M is the only option with those capabilities.

Architecture Differences

The architectural gap between these two cards is vast, reflecting their release dates of 2016 for the AMD and 2022 for the Intel. The AMD Radeon Pro Duo is built on the GCN 3.0 architecture, utilizing a chip codenamed "Capsaicin." It is manufactured on a 28 nm process at TSMC, which seems primitive compared to the Intel's 6 nm process from the same foundry.

The Radeon Pro Duo packs a massive 8,900 million transistors on a die size of 596 mm², resulting in a transistor density of 14.9M / mm². In contrast, the Intel Arc A370M uses the Xe-HPG architecture with a chip called "DG2-128." It contains 7,200 million transistors on a much smaller 157 mm² die, yielding a significantly higher density of 45.9M / mm². This difference in density is a direct result of the more advanced manufacturing process and architectural design.

The memory subsystems could not be more different. The AMD card uses 4 GB of HBM memory on a 4096-bit bus, delivering a staggering 512.0 GB/s of bandwidth. The Intel card also has 4 GB, but it is GDDR6 on a 64-bit bus, providing 112.0 GB/s of bandwidth. While the Pro Duo's bandwidth is a major advantage for large datasets, the Arc's memory is more power-efficient.

In terms of compute units, the AMD Radeon Pro Duo has 4,096 shading units, 256 TMUs, and 64 ROPs. It lacks dedicated ray tracing cores. The Intel Arc A370M has 1,024 shading units, 64 TMUs, and 32 ROPs, but it includes 8 dedicated ray tracing cores. This makes the Arc the only card here capable of hardware-accelerated ray tracing.

The FP32 and FP16 performance also highlights different design goals. The AMD card delivers 8.192 TFLOPS for both FP32 and FP16, a 1:1 ratio. The Intel card delivers 4.198 TFLOPS for FP32 but 8.397 TFLOPS for FP16, showcasing a 2:1 ratio that is more efficient for AI and machine learning workloads that often use FP16 precision.

The Verdict

The verdict is a clear split based on priorities. For a desktop workstation that requires the absolute maximum in raw FP32 compute and memory bandwidth, the AMD Radeon Pro Duo is the superior choice. Its 20.8% lead in OpenCL performance and 512.0 GB/s of bandwidth are decisive for heavy compute tasks. It is a professional tool, evidenced by its quad-slot design, 3x 8-pin power connectors, and 750 W suggested PSU.

For any other scenario, the Intel Arc A370M is the better option. Its support for modern APIs like DirectX 12 Ultimate and Vulkan 1.4 makes it future-proof for gaming and contemporary applications. The inclusion of ray tracing cores is a significant feature absent from the AMD card. Its 35 W TDP and IGP slot width clearly indicate its purpose as a mobile component, offering a level of efficiency and portability that the 350 W, 277 mm long AMD card cannot even approach. The Arc A370M is the only one of the two that could be used in a laptop.

Head-to-Head Benchmarks

The only direct comparison recorded in the database is the Geekbench OpenCL test, and it is a decisive win for the AMD Radeon Pro Duo. It scores 35,860 against the Intel Arc A370M's 29,676, resulting in a 20.8% performance advantage. This is a substantial difference in a compute-heavy workload. The Pro Duo's massive 512.0 GB/s of memory bandwidth and 8.192 TFLOPS of FP32 throughput provide a clear advantage in tasks that are not bound by power or space.

However, it is critical to consider that the Intel card has an additional benchmark result, scoring 28,673 in Geekbench Vulkan. This shows it is a capable performer in a modern graphics API, and its presence reflects its more contemporary feature set. The AMD card's sole OpenCL result of 35,860 puts it in the 80th percentile of all GPUs, while the Intel's average score of 29,175 lands it in the 74th percentile. This 6-percentile gap in the database ranking reinforces the AMD card's dominant compute position.

When comparing to their respective rivals, the AMD card's nearest competitor is the NVIDIA Quadro GV100, which it beats by only 1%. This places it in the same performance tier as professional workstation cards. The Intel Arc A370M's nearest rival is the AMD Radeon RX Vega M GH, which it trails by a negligible 0.1%, and it is just 0.1% behind the AMD FirePro W8000. It is also 0.6% ahead of the AMD Radeon RX 470 and a full 1% ahead of the AMD Radeon RX 6800M. This shows the Arc A370M is a solid performer within its own class, but it cannot match the raw power of the Pro Duo.
