Intel Arc A370M vs NVIDIA RTX PRO 4500 Blackwell Comparison

The NVIDIA RTX PRO 4500 Blackwell and Intel Arc A370M occupy opposite ends of the GPU spectrum, and the benchmark data reflects that chasm. The RTX PRO 4500 is a 200 W desktop workstation card built on the Blackwell 2.0 architecture, while the Arc A370M is a 35 W mobile IGP from Intel's Alchemist generation. The single head-to-head benchmark available—Geekbench Vulkan—shows a 673.4% advantage for the NVIDIA product, a margin so large that it effectively places the two in different performance categories. The RTX PRO 4500 scores 221,768 against the Arc A370M's 28,673. This is not a close contest; it is a generational and market-segment divide made measurable.

Head-to-Head Benchmarks

The only direct comparison in the data is the Geekbench Vulkan test, and it is decisive. The NVIDIA RTX PRO 4500 Blackwell scores 221,768, while the Intel Arc A370M manages 28,673. That represents a delta of 673.4% in favor of the NVIDIA card. To put that in perspective, the RTX PRO 4500's score is roughly 7.7 times higher than the Arc A370M's output. This single metric captures the entire story: the workstation GPU is engineered for compute-heavy tasks, whereas the Intel part is designed for basic mobile graphics.

The average benchmark scores reinforce this disparity. The RTX PRO 4500 holds an average score of 31,532 across its benchmark suite, which includes PassMark G3D (33,360), PassMark GPU Compute (19,255), and 3DMark Steel Nomad DX12 (7,025). The Arc A370M's average is 29,175, derived from only two tests: Geekbench OpenCL (29,676) and Geekbench Vulkan (28,673). While the averages appear close, this is misleading because the test sets differ entirely; the RTX PRO 4500's average is dragged down by low PassMark DirectX 9/10/11/12 scores, which are legacy API tests that do not reflect its modern capabilities.

The percentile rankings tell a similar story. The RTX PRO 4500 sits at the 76th percentile of all GPUs, while the Arc A370M is at the 74th percentile. Despite the massive Vulkan delta, the Arc A370M is not a weak performer in its class—it sits near the same percentile because its benchmark pool is narrower and its nearest rivals include the AMD Radeon RX Vega M GH (average score 29,197, delta -0.1%) and the AMD Radeon RX 470 (average score 28,996, delta 0.6%). The RTX PRO 4500's nearest rivals include the NVIDIA TITAN RTX (average score 31,676, delta -0.5%) and the Intel Arc Pro A30M (average score 31,894, delta -1.1%). This shows the RTX PRO 4500 is competing with high-end desktop parts, while the Arc A370M is in the mid-range mobile segment.

Architecture Differences

The architectural gap is as wide as the performance gap. The RTX PRO 4500 uses the GB203 chip on a 5 nm TSMC process, packing 45,600 million transistors into a 378 mm² die. That yields a transistor density of 120.6 million per mm². The Arc A370M uses the DG2-128 chip on a 6 nm TSMC process, with 7,200 million transistors on a 157 mm² die, for a density of 45.9 million per mm². The NVIDIA chip has over six times the transistor count and a density nearly three times higher, explaining its massive compute advantage.

Memory architecture diverges completely. The RTX PRO 4500 features 32 GB of GDDR7 memory on a 256-bit bus, delivering 896.0 GB/s of bandwidth. The Arc A370M has 4 GB of GDDR6 on a 64-bit bus, yielding 112.0 GB/s. That is an 8x difference in capacity and an 8x difference in bandwidth. The NVIDIA card also runs its memory at 28 Gbps effective, double the Arc A370M's 14 Gbps effective rate. For workloads that are memory-bound—such as large dataset processing in workstation applications—this is a decisive factor.

Compute resources follow the same pattern. The RTX PRO 4500 has 10,496 shading units, 328 TMUs, and 112 ROPs, along with 82 RT cores and 328 tensor cores. The Arc A370M has 1,024 shading units, 64 TMUs, and 32 ROPs, with just 8 RT cores and no tensor cores. The FP32 throughput is 50.53 TFLOPS for the NVIDIA card versus 4.198 TFLOPS for the Intel part—a 12x difference. The RTX PRO 4500 also maintains a 1:1 FP16 ratio (50.53 TFLOPS), whereas the Arc A370M offers 8.397 TFLOPS at a 2:1 ratio, meaning its FP16 performance is halved when used for compute. Pixel rate is 269.6 GPixel/s versus 65.60 GPixel/s, and texture rate is 789.5 GTexel/s versus 131.2 GTexel/s.

Where Each One Wins

The NVIDIA RTX PRO 4500 Blackwell wins in every measured performance category. It dominates compute workloads, with 50.53 TFLOPS FP32 and 50.53 TFLOPS FP16, making it suitable for AI inference, rendering, and scientific simulation. Its 32 GB of GDDR7 memory with 896.0 GB/s bandwidth is ideal for large datasets, 3D modeling, and video editing. The 82 RT cores and 328 tensor cores provide hardware acceleration for ray tracing and deep learning tasks. The 673.4% Vulkan benchmark advantage confirms it as the choice for any graphics-intensive professional application.

The Intel Arc A370M wins in power efficiency and mobility. Its 35 W TDP is less than one-fifth of the RTX PRO 4500's 200 W, making it suitable for thin-and-light laptops. As an IGP, it requires no additional power connector and is portable device dependent for display output. Its 4 GB of GDDR6 memory is sufficient for basic gaming and light productivity. While its 4.198 TFLOPS FP32 is modest, it still places at the 74th percentile of all GPUs, outperforming rivals like the AMD Radeon RX 470 (average score 28,996, delta 0.6%). For users needing a capable integrated GPU without the power budget of a discrete workstation card, the Arc A370M is the practical choice.

The specification differences also dictate use cases. The RTX PRO 4500's PCIe 5.0 x16 interface and 4x DisplayPort 2.1b outputs support multi-monitor professional setups, while the Arc A370M's PCIe 4.0 x8 and portable device dependent outputs limit it to laptop displays. The RTX PRO 4500's dual-slot design and 550 W suggested PSU indicate a desktop workstation environment, whereas the Arc A370M's IGP form factor is for mobile systems. In short, the NVIDIA card is for workloads that demand maximum performance without regard to power, while the Intel card is for portable systems where efficiency and integration are paramount.
