Intel Arc B370 vs NVIDIA RTX PRO 6000 Blackwell Comparison

Intel Arc B370 and NVIDIA RTX PRO 6000 Blackwell sit at opposite extremes of the GPU spectrum, and the recorded data reflects that divide clearly. The Arc B370 is an integrated graphics solution aimed at portable devices, while the RTX PRO 6000 Blackwell is a dual-slot workstation card with a 600 W power draw. Their single shared benchmark, 3dmark Steel Nomad DX12, shows a 92.8% gap in favor of the NVIDIA part, but the analysis does not end at raw performance. The two products serve entirely different physical and architectural contexts, and the data explains why.

Where Each One Wins

The NVIDIA RTX PRO 6000 Blackwell wins the only head-to-head benchmark recorded in the database. It scores 16408 in 3dmark Steel Nomad DX12, while the Intel Arc B370 scores 1184, a delta of -92.8% for the Intel part. This is not a close contest, and the percentile data reinforces the separation. The RTX PRO 6000 sits at the 59th percentile among all GPUs, while the Arc B370 sits at the 5th percentile. In direct comparison, the NVIDIA card delivers a score that is 13.9 times higher than the Intel integrated solution.

The Intel Arc B370 wins in the context of physical integration and power efficiency, though the benchmark database does not record a direct performance win for it. Its 25 W TDP and IGP slot width mean it requires no power connectors and no dedicated cooler, making it suitable for thin portable devices. The RTX PRO 6000, by contrast, demands a 1000 W suggested PSU and a dual-slot chassis with a 16-pin connector. The Arc B370 also uses system shared memory, which eliminates the need for dedicated VRAM modules, a trait that aligns with its integrated design.

Where the RTX PRO 6000 clearly wins is in every measurable performance metric recorded. Its 126.0 TFLOPS FP32 throughput dwarfs the Arc B370's 6.144 TFLOPS. Its 1.79 TB/s memory bandwidth against the Arc's system dependent bandwidth shows a massive difference in data handling capability. The 96 GB GDDR7 frame buffer versus system shared memory means the NVIDIA card can hold far larger datasets locally. For workloads that stress rasterization, ray tracing, or tensor operations, the RTX PRO 6000 is the only viable choice based on the data.

Architecture Differences

The two chips share no common design lineage. The Intel Arc B370 uses the Panther Lake chip with Xe3-LPG architecture, built on a 3 nm process at Intel. The NVIDIA RTX PRO 6000 Blackwell uses the GB202 chip with Blackwell 2.0 architecture, built on a 5 nm process at TSMC. The process node difference is counterintuitive: Intel uses the smaller 3 nm node, yet the NVIDIA chip has vastly more compute resources.

The RTX PRO 6000 packs 92,200 million transistors on a 750 mm² die, with a transistor density of 122.9M per mm². The Arc B370's transistor count and die size are listed as unknown in the database, so no direct density comparison is possible. The NVIDIA card also has a massive resource advantage in every unit category: 24064 shading units versus 1280, 752 TMUs versus 40, 192 ROPs versus 20, 188 RT cores versus 10, and 752 tensor cores versus none listed for the Intel part.

Memory architecture differs fundamentally. The Arc B370 uses system shared memory, meaning its frame buffer is borrowed from the host system, with bandwidth described as system dependent. The RTX PRO 6000 has dedicated 96 GB of GDDR7 on a 512 bit bus, delivering 1.79 TB/s of bandwidth. Clock behavior also differs: the Arc B370 runs at a 300 MHz base and 2400 MHz boost, while the NVIDIA card runs at 1590 MHz base and 2617 MHz boost. Despite the higher base clock, the NVIDIA card's massive parallel resources account for its dominant throughput.

API support is identical: both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The RTX PRO 6000 adds 752 tensor cores, which the Arc B370 lacks entirely, a feature gap that matters for AI and compute workloads. The NVIDIA card also has a 16-pin power connector, a 1000 W suggested PSU, and a dual-slot, 304 mm long, 137 mm high, 40 mm wide physical footprint. The Arc B370 is listed as IGP with no dimensions, no power connector, and a 25 W TDP.

The Verdict

The data supports a clear split: the NVIDIA RTX PRO 6000 Blackwell is for workstation-class tasks that demand maximum compute, memory capacity, and bandwidth, while the Intel Arc B370 is for low-power integrated graphics in portable devices. The RTX PRO 6000 outscores the Arc B370 by 92.8% in the only shared benchmark, and its 126.0 TFLOPS FP32 versus 6.144 TFLOPS shows a 20.5x raw compute advantage. Its 96 GB memory versus system shared, and 1.79 TB/s versus system dependent bandwidth, make it the only option for large datasets.

The Arc B370's role is defined by its 25 W TDP and IGP integration. It uses no power connectors, fits in a portable device, and relies on shared system memory. It cannot compete on any recorded performance metric, but it does not need to, as its design targets a different physical form factor. The RTX PRO 6000, with its 600 W TDP and dual-slot size, is not a portable part. Its 59th percentile ranking versus the Arc's 5th percentile confirms that the NVIDIA card sits in a far higher performance tier.

Users who need to render large scenes, run AI inference with tensor cores, or process high-resolution video should choose the RTX PRO 6000. Users who need basic graphics acceleration in a thin laptop or compact device should use the Arc B370. There is no scenario in the data where the Intel part outperforms the NVIDIA part in compute, memory, or benchmark score.
