Intel Arc B370 vs NVIDIA RTX PRO 4000 Blackwell SFF Comparison

Head-to-Head Benchmarks

The recorded data contains a single direct comparison in 3DMark Steel Nomad (DX12). The NVIDIA RTX PRO 4000 Blackwell SFF delivers a score of 2910, while the Intel Arc B370 records 1184. That is a delta of -59.3% for the Intel part, meaning NVIDIA's card is approximately 2.46 times faster in this workload. The result is unambiguous: the RTX PRO 4000 Blackwell SFF wins the only head-to-head test, and it wins by a wide margin.

Looking at the broader database context, the Intel Arc B370 sits in the 5th percentile of all GPUs. Its nearest rivals are older discrete parts: the ATI Mobility Radeon HD 5570 scores 1186 (0.2% ahead), the ATI Radeon HD 5770 scores 1190 (0.5% ahead), and the AMD Radeon HD 7650M scores 1192 (0.7% ahead). The AMD FirePro M2000 trails at 1168, which is 1.4% behind the Arc B370. This places the Intel part in a performance band populated by legacy mobile and entry-level desktop GPUs from over a decade ago. The Arc B370 is not competitive with modern discrete graphics in this benchmark, despite being built on a 3 nm process and using Intel's Xe3-LPG architecture.

The NVIDIA RTX PRO 4000 Blackwell SFF, by contrast, sits in the 19th percentile of all GPUs. Its nearest rivals are modern desktop parts: the GeForce RTX 4060 Ti 16 GB scores 2907 (0.1% behind), the GeForce RTX 4060 Ti 8 GB scores 2913 (0.1% ahead), and the GeForce RTX 4010 scores 2893 (0.6% behind). The Quadro P600 scores 2923, which is 0.4% ahead. The RTX PRO 4000 Blackwell SFF is essentially performance-equivalent to an RTX 4060 Ti class card in Steel Nomad, which is a far more relevant performance tier for contemporary workloads.

The absolute gap between the two is 1726 points. Relative to the Intel part's own score, that is a 145.8% improvement. No other benchmark data exists for either product in the database, so the Steel Nomad result is the sole quantitative basis for comparison.

Architecture Differences

The two GPUs come from fundamentally different design philosophies. Intel's Arc B370 uses the Panther Lake chip with the Xe3-LPG architecture, fabricated on a 3 nm process at Intel's own foundry. It belongs to the Arc Graphics-M (Panther Lake) generation. The NVIDIA part uses the GB203 chip with Blackwell 2.0 architecture, fabricated on a 5 nm process at TSMC, and belongs to the Blackwell PRO W (x000) generation.

The transistor counts differ enormously. NVIDIA's GB203 packs 45,600 million transistors on a 378 mm² die, giving a transistor density of 120.6M per mm². Intel does not disclose the transistor count or die size for the Arc B370, so no density figure can be calculated from the database. The process node advantage goes to Intel at 3 nm versus 5 nm, but the NVIDIA chip compensates with a much larger and more densely populated die.

Compute resources are heavily skewed toward NVIDIA. The RTX PRO 4000 Blackwell SFF has 8960 shading units, 280 TMUs, 96 ROPs, 70 RT cores, and 280 tensor cores. The Intel Arc B370 has 1280 shading units, 40 TMUs, 20 ROPs, and 10 RT cores. Intel does not list tensor cores for the Arc B370. The raw throughput figures confirm the gap: NVIDIA delivers 24.05 TFLOPS FP32 and 24.05 TFLOPS FP16 (1:1 ratio), while Intel delivers 6.144 TFLOPS FP32 and 12.29 TFLOPS FP16 (2:1 ratio). Pixel rate is 128.8 GPixel/s for NVIDIA versus 48.00 GPixel/s for Intel, and texture rate is 375.8 GTexel/s versus 96.00 GTexel/s.

Clock speeds tell an interesting story. The Intel part has a lower base clock of 300 MHz but boosts to 2400 MHz. The NVIDIA part has a base of 405 MHz and a boost of 1342 MHz. Despite the higher boost clock on Intel, the sheer difference in execution resources makes the NVIDIA card far faster in absolute terms. Memory clocks also differ: Intel uses system-shared memory with no dedicated clock, while NVIDIA uses 1125 MHz with 18 Gbps effective GDDR7.

Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The bus interfaces differ: Intel uses IGP, while NVIDIA uses PCIe 5.0 x8. Display outputs also differ: Intel lists "Portable Device Dependent," while NVIDIA provides 4x mini-DisplayPort 2.1b.

The Verdict

The benchmark data is decisive. The NVIDIA RTX PRO 4000 Blackwell SFF is the faster GPU by a substantial margin in 3DMark Steel Nomad DX12, with a score of 2910 against 1184 for the Intel Arc B370. The Intel part's percentile ranking of 5 places it alongside legacy ATI GPUs from the HD 5000 and HD 7000 series era, while the NVIDIA part's 19th percentile places it in the same performance class as the GeForce RTX 4060 Ti family.

For workloads that depend on raw GPU throughput, including FP32 compute, texture filtering, and pixel fill, the NVIDIA card holds commanding leads: 24.05 TFLOPS versus 6.144 TFLOPS FP32, 375.8 GTexel/s versus 96.00 GTexel/s, and 128.8 GPixel/s versus 48.00 GPixel/s. The NVIDIA card also offers 24 GB of dedicated GDDR7 memory with 432.0 GB/s bandwidth, whereas the Intel part relies on system-shared memory with system-dependent bandwidth.

The Intel Arc B370 is a 25 W integrated GPU within the Panther Lake platform. Its role is clearly in power-constrained, portable devices where discrete graphics is not an option. The NVIDIA RTX PRO 4000 Blackwell SFF is a 70 W dual-slot discrete card with a suggested 250 W PSU, designed for small-form-factor workstations.

The data supports a clear split: the Intel Arc B370 is suitable for light, integrated graphics duty, while the NVIDIA RTX PRO 4000 Blackwell SFF is the appropriate choice for any workload requiring professional-grade 3D performance. The 59.3% deficit in the sole head-to-head benchmark is too large to overcome, and no other benchmark results exist to suggest the Intel part is competitive in any other 3D workload.

Where Each One Wins

The NVIDIA RTX PRO 4000 Blackwell SFF wins the only recorded benchmark, 3DMark Steel Nomad DX12, by a 59.3% margin. It also wins on every raw compute metric in the database: FP32 throughput, FP16 throughput, pixel fill rate, texture fill rate, shading units, TMUs, ROPs, RT cores, and tensor cores. Its 24 GB GDDR7 memory with 432.0 GB/s bandwidth gives it a decisive advantage in any memory-bound workload, and its PCIe 5.0 x8 interface allows high-bandwidth host communication. The dual-slot form factor with four mini-DisplayPort 2.1b outputs makes it suitable for multi-display professional setups.

The Intel Arc B370 wins on integration and power efficiency. Its 25 W TDP is less than half the NVIDIA part's 70 W TDP, and it requires no power connectors. As an IGP with no separate slot width, it occupies no expansion slot and needs no suggested PSU. Its 3 nm process node is more advanced than the 5 nm node used by NVIDIA, and its 2400 MHz boost clock is substantially higher than the NVIDIA card's 1342 MHz. For portable devices where system-shared memory is the only option and discrete graphics cannot be installed, the Arc B370 is the only viable choice of the two. It also carries a later release date of 2026-01-26 versus 2025-08-10 for the NVIDIA part.

The data indicates no scenario where the Intel part wins a performance comparison. Its nearest rivals in the database are ATI Mobility Radeon HD 5570, ATI Radeon HD 5770, AMD Radeon HD 7650M, and AMD FirePro M2000, all of which are within 1.4% of its score. The NVIDIA part's nearest rivals are RTX 4060 Ti class GPUs. The performance tiers are simply different. The Intel Arc B370 is a low-power integrated solution, and the NVIDIA RTX PRO 4000 Blackwell SFF is a small-form-factor workstation card. Each wins in its intended deployment class, but only one wins in actual 3D performance.
