AMD Radeon PRO W7800 vs Intel Arc B370 Comparison

Where Each One Wins

The performance split between these two GPUs is not a contest of equals. The AMD Radeon PRO W7800 occupies a completely different performance tier, while the Intel Arc B370 is an integrated graphics processor designed for mobility. Benchmark data confirms this separation: the AMD part scores 154,366 in Geekbench OpenCL and 175,422 in Geekbench Vulkan, while the Intel part records 1,184 in 3DMark Steel Nomad DX12. The AMD card sits in the 97th percentile of all GPUs in the database, while the Intel iGPU sits in the 5th percentile.

The Radeon PRO W7800 wins in every category where raw compute throughput matters. Its FP32 output of 45.25 TFLOPS versus the Arc B370's 6.144 TFLOPS indicates a 7.4x gap in single-precision compute. The AMD card also delivers 90.50 TFLOPS FP16 (2:1) versus the Intel part's 12.29 TFLOPS FP16 (2:1). These figures point to workloads such as large dataset processing, scientific simulation, and professional 3D rendering, where massive parallel throughput translates directly into reduced wall-clock time.

The Intel Arc B370 wins in the categories of power consumption and physical footprint. Its 25 W TDP is a fraction of the Radeon PRO W7800's 260 W TDP. The Intel part is an IGP with no dedicated power connectors and no slot width, meaning it integrates directly into a processor package. The AMD card requires a dual-slot cooler and two 8-pin power connectors, along with a 600 W suggested PSU. The Arc B370's memory setup is System Shared, with bandwidth described as System Dependent. This makes it suitable for thin-and-light portable devices where dedicated graphics cards physically cannot fit.

The data shows that the AMD Radeon PRO W7800 is a workstation-class accelerator for compute-heavy tasks, while the Intel Arc B370 is a low-power integrated solution for basic graphics acceleration in portable systems. There is no overlap in their intended use cases.

Architecture Differences

The two GPUs come from different manufacturers, different foundries, and different process nodes. The AMD Radeon PRO W7800 uses the Navi 31 chip, built on RDNA 3.0 architecture with the codename Plum Bonito. It is fabricated on a 5 nm process at TSMC, with 57,700 million transistors packed into a 529 mm² die, yielding a transistor density of 109.1M per mm². The Intel Arc B370 uses the Panther Lake chip, built on Xe3-LPG architecture, fabricated on a 3 nm process at Intel. Its transistor count and die size are listed as unknown in the database.

The memory subsystems differ fundamentally. The AMD card carries 32 GB of GDDR6 memory on a 256-bit bus, delivering 576.0 GB/s of bandwidth at an effective 18 Gbps memory clock. The Intel part has no dedicated VRAM: its memory size, type, and bus width are all labeled System Shared, with bandwidth dependent on the host system. This is a defining architectural split. The Radeon PRO W7800 can sustain high-bandwidth streams of data for large models and textures. The Arc B370 must compete for system memory bandwidth with the CPU and other components.

The compute resources also diverge sharply. The AMD GPU has 4,480 shading units, 280 texture mapping units, 128 ROPs, and 70 ray tracing cores. The Intel GPU has 1,280 shading units, 40 TMUs, 20 ROPs, and 10 ray tracing cores. The AMD part's pixel rate is 323.2 GPixel/s versus the Intel part's 48.00 GPixel/s. Texture rate is 707.0 GTexel/s versus 96.00 GTexel/s. These are not incremental differences; the AMD card has roughly 3.5x the shaders, 7x the TMUs, 6.4x the ROPs, and 7x the ray tracing cores.

Clock behavior also reflects their different roles. The AMD card runs at a 1,895 MHz base clock and 2,525 MHz boost clock. The Intel part has a 300 MHz base clock and 2,400 MHz boost clock. The lower base clock on the Intel part suggests aggressive power gating for idle efficiency, while the boost clock approaches the AMD card's level for short bursts. The AMD card's memory clock is fixed at 2,250 MHz with 18 Gbps effective data rate.

Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Both have null tensor core counts in the database, meaning neither is specialized for matrix operations in the same way as dedicated tensor-core hardware. The AMD card connects via PCIe 4.0 x16, while the Intel part uses an integrated graphics processor bus interface labeled IGP.

The AMD card's display outputs include 3x DisplayPort 2.1 and 1x mini-DisplayPort 2.1. The Intel part's display outputs are listed as Portable Device Dependent, reflecting its integration into a mobile processor. The release dates also differ: the AMD card launched on 2023-04-12, while the Intel part is set for 2026-01-26.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries between these two GPUs. Instead, each has its own benchmark suite, and the scores place them in vastly different percentile ranges.

The AMD Radeon PRO W7800's average benchmark score is 164,894. Its nearest rivals in the database include the NVIDIA RTX A5500 with an average score of 165,217, a delta of -0.2% meaning the AMD card trails by 0.2%. The NVIDIA RTX 4500 Ada Generation scores 166,094, a delta of -0.7%. The AMD Radeon Pro W6900X scores 168,574, a delta of -2.2%, meaning the AMD card trails that product by 2.2%. The NVIDIA A100 PCIe 40 GB scores 162,504, and the Radeon PRO W7800 leads it by 1.5%. These deltas show the AMD workstation card sits in a tight competitive band around the 165,000 average score mark, within roughly 2% of its nearest rivals.

The Intel Arc B370's average benchmark score is 1,184. Its nearest rivals are all older or lower-end parts. The ATI Mobility Radeon HD 5570 scores 1,186, a delta of -0.2%. The ATI Radeon HD 5770 scores 1,190, a delta of -0.5%. The AMD Radeon HD 7650M scores 1,192, a delta of -0.7%. The AMD FirePro M2000 scores 1,168, and the Intel part leads it by 1.4%. This places the Arc B370 in the company of integrated and entry-level discrete GPUs from over a decade ago, at least in this particular DirectX 12 workload.

The single benchmark recorded for the Intel part is 3DMark Steel Nomad DX12 with a score of 1,184. The AMD card's two benchmarks, Geekbench OpenCL at 154,366 and Geekbench Vulkan at 175,422, are different test suites, so direct score-to-score comparison is not possible. However, the percentile rankings tell the story: the AMD card sits at the 97th percentile of all GPUs, while the Intel part sits at the 5th percentile. This is a 92-point gap in percentile ranking, indicating the AMD card outperforms the overwhelming majority of GPUs in the database, while the Intel part outperforms only a small fraction.

The wins tally from the database shows winsA: 0 and winsB: 0 for head-to-head benchmarks, which confirms there are no shared test results to compare directly. All comparative statements must rely on the nearest rival deltas and the percentile placements.

The Verdict

The data supports a clear division of purpose. The AMD Radeon PRO W7800 is a professional workstation GPU with 32 GB of dedicated GDDR6 memory, a 256-bit memory bus, and 576.0 GB/s bandwidth. Its compute resources are substantial: 4,480 shaders, 70 ray tracing cores, and 45.25 TFLOPS FP32. It ranks in the 97th percentile of all GPUs and trades within 2.2% of its nearest rivals, which include the NVIDIA RTX A5500, RTX 4500 Ada Generation, A100 PCIe 40 GB, and AMD Radeon Pro W6900X. This is a card for users who need high-bandwidth memory and massive parallel throughput in a dual-slot, 260 W package.

The Intel Arc B370 is an integrated GPU with 1,280 shaders, 10 ray tracing cores, and 6.144 TFLOPS FP32. It uses system shared memory and carries a 25 W TDP. It ranks in the 5th percentile and matches the performance level of decade-old discrete and mobile GPUs. Its advantage is integration: no power connectors, no slot width, and a 3 nm process node from Intel. This is a part for portable devices where a dedicated GPU cannot exist.

A user selecting between these two parts is not comparing two products in the same category. The Radeon PRO W7800 is for professional rendering, simulation, and compute workloads that demand dedicated VRAM and high throughput. The Arc B370 is for basic graphics in a low-power mobile processor. The recorded data shows no scenario where the Intel part approaches the AMD card's performance, and no scenario where the AMD card fits the physical and power constraints of the Intel part. The choice is dictated entirely by the target system and workload.
