Intel Arc A370M vs NVIDIA RTX PRO 4000 Blackwell Comparison

Head-to-Head Benchmarks

The single available head-to-head benchmark decisively favors the NVIDIA RTX PRO 4000 Blackwell, but the comparison is not as lopsided as the raw score suggests when placed in context. In Geekbench Vulkan, the NVIDIA card scores 194,168 points against the Intel Arc A370M's 28,673 points, producing a delta of -85.2% for the Intel part. That is a massive gap — roughly 6.8 times the performance — and it reflects the fundamental positioning of these two products rather than any anomaly in the data.

The Intel Arc A370M's average benchmark score across all tests is 29,175, which places it in the 74th percentile of all GPUs tracked by the database. The NVIDIA RTX PRO 4000 Blackwell averages 27,135 across its broader test suite, sitting in the 72nd percentile. These percentile rankings are remarkably close despite the enormous Vulkan delta, because the NVIDIA card's benchmark set includes several Passmark tests that drag its average down — specifically a Passmark DirectX 12 score of 97 and a DirectX 10 score of 173. The Intel card, by contrast, has only two benchmark entries (Geekbench OpenCL and Vulkan), both in the high 28,000 to 29,000 range.

Looking at the nearest rivals for each card clarifies the picture further. The Intel Arc A370M sits within 1% of the AMD Radeon RX Vega M GH (29,197, -0.1%), the AMD FirePro W8000 (29,211, -0.1%), and the AMD Radeon RX 470 (28,996, +0.6%). The NVIDIA RTX PRO 4000 Blackwell is comparably close to the AMD Radeon RX 6700 XT (27,425, -1.1%), the NVIDIA GeForce RTX 4070 Mobile (27,435, -1.1%), and the NVIDIA GeForce RTX 3090 (27,565, -1.6%). The data indicates both cards are competitively positioned within their respective performance tiers, with the NVIDIA card actually trailing the RTX 3090 by 1.6% in average score despite being a newer generation.

Architecture Differences

The architectural chasm between these two GPUs is stark and explains nearly every performance and feature difference. The Intel Arc A370M uses the DG2-128 chip built on TSMC's 6 nm process, packing 7,200 million transistors into a 157 mm² die. The transistor density works out to 45.9 million per mm². The NVIDIA RTX PRO 4000 Blackwell uses the GB203 chip on TSMC's 5 nm node, with 45,600 million transistors spread across a 378 mm² die — a density of 120.6 million per mm². That is roughly 2.6 times the transistor density, which is a direct consequence of the more advanced process node and NVIDIA's larger design.

The Intel part is built on Xe-HPG architecture from the Alchemist generation, specifically the Arc 3 Mobile lineup. The NVIDIA card uses Blackwell 2.0 architecture from the Blackwell PRO W (x000) generation. The clock speeds are surprisingly similar — Intel's base clock is 1,550 MHz with a 2,050 MHz boost, while NVIDIA's base is 1,230 MHz with a 2,055 MHz boost. The boost clocks are nearly identical, but the underlying execution resources differ by an order of magnitude.

Intel's Arc A370M has 1,024 shading units, 64 texture mapping units, and 32 ROPs. The RTX PRO 4000 Blackwell has 8,960 shading units, 280 TMUs, and 96 ROPs. That is 8.75 times more shading units, over 4 times more TMUs, and 3 times more ROPs. The ray tracing hardware tells a similar story: Intel has 8 RT cores, while NVIDIA has 70. Intel lists no tensor cores, whereas NVIDIA has 280. This is a class difference, not a generation difference — the Intel part is a mobile entry-level GPU, while the NVIDIA card is a professional workstation part.

Memory architecture reinforces the divide. Intel uses 4 GB of GDDR6 on a 64-bit bus, delivering 112.0 GB/s of bandwidth. NVIDIA uses 24 GB of GDDR7 on a 192-bit bus, delivering 672.0 GB/s. That's 6 times the memory capacity and exactly 6 times the bandwidth. The memory clock shows a 1,750 MHz base for both, but the effective data rates differ (14 Gbps for Intel versus 28 Gbps for NVIDIA). The NVIDIA card also uses a PCIe 5.0 x16 interface versus Intel's PCIe 4.0 x8.

Where Each One Wins

The Intel Arc A370M wins in power efficiency and physical footprint. Its TDP is 35 W versus 140 W for the NVIDIA card — a 4x difference. The Intel part is an IGP (integrated graphics processor) with no dedicated power connectors, while the NVIDIA card is a single-slot, 241 mm long card requiring a 16-pin connector and a 300 W suggested power supply. For thin-and-light laptops or compact systems where power delivery and space are constrained, the Intel part is the only viable option in this comparison.

The Intel card also wins on portability of form factor — it's listed as "Portable Device Dependent" for display outputs, meaning it's designed to be integrated into a device rather than installed as a discrete component. The NVIDIA card offers 4x DisplayPort 2.1b outputs, which is typical for a workstation card intended for multi-monitor professional setups.

The NVIDIA RTX PRO 4000 Blackwell wins every raw performance category. It produces 197.3 GPixel/s pixel rate versus 65.60 GPixel/s for Intel (3x faster), 575.4 GTexel/s texture rate versus 131.2 GTexel/s (4.4x faster), and 36.83 TFLOPS FP32 versus 4.198 TFLOPS (8.8x faster). The FP16 numbers are even more telling: NVIDIA achieves 36.83 TFLOPS at a 1:1 ratio, while Intel manages 8.397 TFLOPS at a 2:1 ratio — meaning NVIDIA's FP16 throughput is 4.4x higher and doesn't require a throughput penalty.

The NVIDIA card also wins on production status. It is marked "Active," with a release date of 2025-03-17, while the Intel part is "End-of-life" with a release date of 2022-03-29. For buyers looking at long-term driver support and availability, the NVIDIA card is clearly the safer choice.

The Verdict

The data makes the choice straightforward for anyone with a clear use case. If the workload requires maximum compute throughput, large memory capacity, professional display outputs, or ray tracing performance, the NVIDIA RTX PRO 4000 Blackwell is the only option. It delivers 8.8x higher FP32 throughput, 6x more memory, 6x more bandwidth, and 8.75x more shading units. The 70 RT cores versus 8, and 280 tensor cores versus none, make it the clear choice for any ray-traced or AI-accelerated workload. The NVIDIA card's higher TDP of 140 W is a trade-off, but it comes with a 300 W suggested PSU rating that is standard for workstation-class hardware.

The Intel Arc A370M has exactly one meaningful advantage: power consumption. At 35 W with no external power connectors and an IGP form factor, it is designed for mobile devices where the NVIDIA card physically cannot fit. The Intel part's 74th percentile ranking versus NVIDIA's 72nd is misleading in this context — those rankings reflect different benchmark suites, and the single shared test (Geekbench Vulkan) shows an 85.2% performance gap in NVIDIA's favor.

For a professional workstation, a content creation rig, or any multi-monitor setup requiring DisplayPort 2.1b, the RTX PRO 4000 Blackwell is the data-supported choice. For an ultra-portable device where power draw and physical space are the primary constraints, the Arc A370M remains a capable option — but it is an end-of-life product, and its 4 GB memory capacity will limit modern workloads. The verdict is clear: these are not competing products. They serve different markets, and the benchmark data reflects that separation.
