Analysis: Intel Arc B370 vs NVIDIA RTX PRO 4000 Blackwell
Where Each One Wins
The benchmark data paints a clear picture of two products aimed at entirely different segments. The Intel Arc B370 is an integrated graphics processor, part of the Panther Lake mobile lineup, and its single recorded benchmark result places it at the 5th percentile among all GPUs. The NVIDIA RTX PRO 4000 Blackwell, a discrete workstation card based on the GB203 chip, sits at the 72nd percentile. In the only shared test, 3DMark Steel Nomad DX12, the NVIDIA card wins outright. The data shows zero benchmark wins for the Intel Arc B370 and one decisive win for the NVIDIA RTX PRO 4000 Blackwell.
The Intel Arc B370 operates with a 25 W thermal design power and uses system-shared memory, making it suitable for lightweight, power-constrained portable devices. Its 1280 shading units and 10 ray tracing cores deliver 6.144 TFLOPS of FP32 compute. The NVIDIA RTX PRO 4000 Blackwell, by contrast, offers 8960 shading units, 70 ray tracing cores, and 280 tensor cores, producing 36.83 TFLOPS of FP32 performance. It carries 24 GB of dedicated GDDR7 memory on a 192-bit bus with 672.0 GB/s of bandwidth, a configuration that supports professional rendering, large dataset manipulation, and compute-heavy workloads.
The benchmark split is therefore not competitive in the traditional sense. The Intel part is designed for basic graphics and media tasks within an integrated environment, while the NVIDIA part targets workstation-class performance. The recorded data confirms that any application requiring substantial GPU throughput will favor the NVIDIA product by a wide margin. The Intel Arc B370's nearest rivals in the database, such as the ATI Mobility Radeon HD 5570 and AMD FirePro M2000, all sit within a narrow band of scores around 1184, indicating its performance class is legacy mobile and entry-level discrete parts from over a decade ago. The NVIDIA RTX PRO 4000 Blackwell's nearest rivals include the AMD Radeon RX 6700 XT and NVIDIA GeForce RTX 3090, placing it firmly in modern high-end territory.

Head-to-Head Benchmarks
The only direct comparison available in the database is the 3DMark Steel Nomad DX12 test. The NVIDIA RTX PRO 4000 Blackwell delivers a score of 4648 against the Intel Arc B370's 1184. This represents a delta of -74.5% for the Intel part, meaning it trails by nearly three-quarters of the NVIDIA card's performance. In absolute terms, the NVIDIA product achieves roughly 3.9 times the score of the Intel integrated GPU.
The magnitude of this gap aligns with the broader specification differences. The NVIDIA card's FP32 throughput of 36.83 TFLOPS is six times higher than the Intel part's 6.144 TFLOPS. Texture fill rate tells a similar story: 575.4 GTexel/s versus 96.00 GTexel/s, a sixfold advantage. Pixel rate is 197.3 GPixel/s versus 48.00 GPixel/s, a fourfold advantage. These ratios confirm that the Steel Nomad result is not an outlier but a consistent reflection of the raw compute and memory resources each GPU can bring to bear.
The Intel Arc B370's nearest rivals in the database, the ATI Mobility Radeon HD 5570 with an average score of 1186 and the AMD FirePro M2000 with 1168, are within 1.4% of its result. This places the Intel part in a performance envelope that predates modern gaming and professional workloads. The NVIDIA RTX PRO 4000 Blackwell's nearest rivals, the AMD Radeon RX 6700 XT at 27425 and the NVIDIA GeForce RTX 3090 at 27565, are within 1.6% of its average benchmark score of 27135. The NVIDIA card's average score across all its recorded benchmarks is 27135, while the Intel part's average is 1184, a 23-fold difference.
Specification Differences
The two GPUs differ in nearly every measurable specification. The Intel Arc B370 uses a 3 nm process node from Intel, while the NVIDIA RTX PRO 4000 Blackwell uses a 5 nm node from TSMC. The NVIDIA chip, GB203, contains 45,600 million transistors on a 378 mm² die with a transistor density of 120.6M per mm². The Intel chip, Panther Lake, has unknown transistor count and die size.
Clock speeds diverge significantly. The Intel part has a base clock of 300 MHz and a boost clock of 2400 MHz. The NVIDIA card has a base clock of 1230 MHz and a boost clock of 2055 MHz. Memory clocks are also different: the Intel GPU uses system-shared memory, while the NVIDIA card runs at 1750 MHz with 28 Gbps effective speed.
Memory specifications are fundamentally different. The Intel Arc B370 has no dedicated VRAM, relying on system memory with system-dependent bandwidth. The NVIDIA RTX PRO 4000 Blackwell has 24 GB of GDDR7 on a 192-bit bus, providing 672.0 GB/s of bandwidth. The shading unit count is 1280 for Intel versus 8960 for NVIDIA. Texture mapping units are 40 versus 280, and raster output units are 20 versus 96. Ray tracing cores are 10 versus 70, and the NVIDIA card includes 280 tensor cores while the Intel part has none listed.
Physical specifications reflect the different form factors. The Intel Arc B370 is an integrated GPU with no slot width, no power connectors, and no dimensions listed. The NVIDIA card is single-slot, measures 241 mm by 111 mm by 20 mm, uses one 16-pin power connector, and requires a 300 W suggested PSU. The bus interface is IGP for Intel and PCIe 5.0 x16 for NVIDIA. Display outputs are portable device dependent for Intel versus four DisplayPort 2.1b for NVIDIA.
Architecture Differences
The Intel Arc B370 is built on the Xe3-LPG architecture, part of the Arc Graphics-M (Panther Lake) generation. It uses the Panther Lake chip and supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Its FP16 performance is 12.29 TFLOPS with a 2:1 ratio, meaning half-rate FP16 execution relative to FP32. The architecture is designed for integrated use in portable devices, with a 25 W TDP and shared system memory.
The NVIDIA RTX PRO 4000 Blackwell is built on the Blackwell 2.0 architecture, part of the Blackwell PRO W (x000) generation, using the GB203 chip. It supports the same API set: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Its FP16 performance matches FP32 at 36.83 TFLOPS with a 1:1 ratio, indicating full-rate FP16 execution. The architecture includes 280 tensor cores, which the Intel part lacks entirely. The NVIDIA card also has 70 ray tracing cores compared to Intel's 10, plus higher texture and pixel throughput rates.
The process node difference is notable: Intel uses a 3 nm process, while NVIDIA uses a 5 nm process. Despite the larger node, the NVIDIA chip packs 45,600 million transistors on a 378 mm² die, yielding a density of 120.6M per mm². The Intel chip's transistor count and die size are not recorded in the database. The NVIDIA card's 140 W TDP is substantially higher than the Intel part's 25 W, reflecting the discrete design with dedicated memory and active cooling. The Intel part's IGP bus interface and lack of power connectors confirm its role as a system-on-chip component, while the NVIDIA card's PCIe 5.0 x16 interface and 16-pin connector indicate a standalone expansion card.
The release dates differ by roughly ten months. The NVIDIA RTX PRO 4000 Blackwell was released in March 2025, while the Intel Arc B370 came later in January 2026. The NVIDIA card's predecessor is listed as Workstation Ada, while the Intel part has no recorded predecessor. Both are currently marked as Active in production status. The recorded data shows no overlap in their intended workloads: the Intel Arc B370's 5th percentile ranking and system-shared memory point to entry-level integrated graphics, while the NVIDIA RTX PRO 4000 Blackwell's 72nd percentile ranking, 24 GB of GDDR7, and tensor core array target professional visualization, AI inference, and high-performance compute. The architecture differences, from FP16 ratio to memory subsystem, reinforce this separation.
