AMD Radeon Pro Duo vs Intel Arc Pro A30M Comparison

Architecture Differences

The AMD Radeon Pro Duo and Intel Arc Pro A30M represent two fundamentally different approaches to GPU design, separated by roughly six years of architectural evolution. The AMD part, built on the GCN 3.0 architecture with the "Capsaicin" chip, is a dual-GPU flagship workstation card from the Radeon Pro GCN generation. It uses a 28 nm process from TSMC, packing 8,900 million transistors onto a massive 596 mm² die. The transistor density works out to 14.9M per mm², which reflects the older, larger process node. In contrast, the Intel Arc Pro A30M uses the Xe-HPG architecture with the DG2-128 chip, part of the Alchemist Pro-Series Mobile lineup. It is fabricated on a much newer 6 nm TSMC process, with 7,200 million transistors on a far smaller 157 mm² die, achieving 45.9M transistors per mm². That is more than three times the transistor density of the AMD card, a direct consequence of the newer manufacturing technology.

The memory subsystems diverge sharply as well. The Radeon Pro Duo carries 4 GB of HBM memory on a 4096-bit bus, producing 512.0 GB/s of bandwidth. The Intel part also has 4 GB, but it uses GDDR6 on a 64-bit bus, yielding only 128.0 GB/s. The AMD card's memory clock is listed at 500 MHz with 1000 Mbps effective, while the Intel part runs at 2000 MHz with 16 Gbps effective. The bus width difference is the dominant factor: the AMD card has 64 times the bus width, which explains its 4x bandwidth advantage despite the older memory technology.

Compute resources also differ substantially. The Radeon Pro Duo has 4096 shading units, 256 TMUs, and 64 ROPs. The Arc Pro A30M has 1024 shading units, 64 TMUs, and 32 ROPs. The AMD card has no dedicated ray tracing cores, while the Intel part includes 8 RT cores. Neither card lists tensor cores. The pixel rate is identical at 64.00 GPixel/s for both, but the texture rate differs: 256.0 GTexel/s for AMD versus 128.0 GTexel/s for Intel. FP32 throughput is 8.192 TFLOPS for the Radeon Pro Duo and 4.096 TFLOPS for the Arc Pro A30M. Interestingly, FP16 performance is the same at 8.192 TFLOPS, but the AMD card achieves this at a 1:1 ratio while the Intel part uses a 2:1 ratio, meaning the Intel GPU's FP16 output comes from the same hardware at half the FP32 rate.

Power and physical characteristics are equally divergent. The Radeon Pro Duo is a 350 W dual-slot card requiring 3x 8-pin power connectors and a 750 W suggested power supply. It measures 277 mm in length and 111 mm in height. The Arc Pro A30M is a mobile part with a 50 W TDP, no power connectors, and no listed dimensions or slot width. The AMD card uses PCIe 3.0 x16, while the Intel part uses PCIe 4.0 x8. Display outputs also differ: the Radeon Pro Duo offers 1x HDMI 1.4a and 3x DisplayPort 1.2, while the Intel GPU's outputs are listed as portable device dependent.

API support shows the generational gap. The AMD card supports DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.2.170. The Intel part supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The higher DirectX feature level and newer Vulkan version on the Intel part reflect its more modern architecture.

Head-to-Head Benchmarks

The database contains one head-to-head benchmark between these two GPUs: Geekbench OpenCL. The AMD Radeon Pro Duo scores 35860, and the Intel Arc Pro A30M scores 31894. The AMD card wins by 12.4%. This is the only recorded benchmark pairing, and the AMD card takes the sole win, with a 1-0 record in head-to-head tests.

Context from the nearest rivals helps interpret these scores. The AMD Radeon Pro Duo sits at the 80th percentile among all GPUs. Its closest competitors are the NVIDIA Quadro GV100 at 35520 (1% behind), the NVIDIA GeForce RTX 5070 Ti Mobile at 35435 (1.2% behind), the NVIDIA T1000 at 36289 (1.2% ahead), and the AMD Radeon RX 5300M at 36529 (1.8% ahead). The margins are tight: the Radeon Pro Duo is essentially at parity with several modern and prosumer GPUs, despite being an older dual-GPU design.

The Intel Arc Pro A30M sits at the 76th percentile. Its nearest rivals include the NVIDIA TITAN RTX at 31676 (0.7% behind), the AMD Radeon Pro 570X at 32176 (0.9% ahead), the NVIDIA RTX PRO 4500 Blackwell at 31532 (1.1% behind), and the AMD FirePro S10000 at 32388 (1.5% ahead). The Intel GPU's score places it in a similar performance band, though slightly lower than the AMD Radeon Pro Duo.

The 12.4% delta in the head-to-head test is larger than any of the deltas within each GPU's nearest rival group. This suggests the performance gap between the two is meaningful in OpenCL workloads, even though both GPUs occupy similar percentile ranges overall. The Radeon Pro Duo's advantage likely stems from its vastly higher memory bandwidth (512.0 GB/s versus 128.0 GB/s) and double the FP32 throughput, which OpenCL compute workloads can exploit.

Where Each One Wins

The AMD Radeon Pro Duo wins the only recorded benchmark, Geekbench OpenCL, by 12.4%. Its strengths lie in raw compute throughput: 8.192 TFLOPS FP32, 4096 shading units, and 512.0 GB/s of memory bandwidth. These specifications make it better suited for OpenCL compute tasks that scale with parallel ALU count and memory bandwidth. The identical pixel rate of 64.00 GPixel/s between the two cards means neither has a fill rate advantage, but the AMD card's double texture rate (256.0 GTexel/s versus 128.0 GTexel/s) gives it an edge in texture-heavy workloads. The dual-slot desktop form factor with 3x 8-pin power connectors indicates it was designed for stationary workstation use where power delivery is not a constraint.

The Intel Arc Pro A30M, despite losing the head-to-head benchmark, has its own distinct advantages. It supports DirectX 12 Ultimate (12_2) versus the AMD card's DirectX 12 (12_0), meaning it can handle the latest graphics feature level. It has 8 dedicated ray tracing cores, which the AMD card lacks entirely. Its Vulkan support is newer at 1.4 versus 1.2.170. The 50 W TDP and lack of power connectors make it far more suitable for mobile or compact systems. The 6 nm process with 45.9M transistors per mm² indicates a much more power-efficient design. Its FP16 throughput matches the AMD card at 8.192 TFLOPS, achieved through a 2:1 ratio, so mixed-precision workloads that can use FP16 may perform comparably.

For use-case segmentation, the AMD Radeon Pro Duo is the choice for compute-heavy OpenCL workloads, high-bandwidth memory access patterns, and texture-intensive rendering tasks where its 512.0 GB/s bandwidth and 4096 shading units can be fully utilized. The Intel Arc Pro A30M is better positioned for modern API features, ray-traced content, portability, and power-constrained environments. Its PCIe 4.0 x8 interface also offers newer bus technology, though the AMD card's PCIe 3.0 x16 provides more lanes overall. The Radeon Pro Duo's 1,499 USD launch MSRP reflects its workstation-class positioning, while the Intel part has no recorded launch MSRP. Ultimately, the benchmark data shows the AMD card leading in raw OpenCL performance, but the Intel card's architectural advantages in API support, ray tracing, and power efficiency make it the more modern option for specific workloads.
