Intel Arc Pro B390 vs NVIDIA RTX PRO 4000 Blackwell SFF Comparison

The Verdict

The database contains only one recorded benchmark result for these two workstation graphics parts, and it belongs exclusively to the NVIDIA RTX PRO 4000 Blackwell SFF. The Intel Arc Pro B390 has no benchmark entries, no average score, and no nearest rivals recorded. The RTX PRO 4000 Blackwell SFF, by contrast, posts a 3DMark Steel Nomad DX12 score of 2910, which places it in the 19th percentile of all GPUs tracked by the database.

The RTX PRO 4000 Blackwell SFF is the only part here with measurable performance data. Its closest recorded rival is the NVIDIA GeForce RTX 4060 Ti 8 GB, which scores 2913, a delta of -0.1 percent, meaning the RTX PRO 4000 trails that card by a negligible margin. It sits 0.1 percent ahead of the GeForce RTX 4060 Ti 16 GB (2907), 0.6 percent ahead of the GeForce RTX 4010 (2893), and 0.4 percent behind the NVIDIA Quadro P600 (2923). The practical conclusion from the recorded data is that the RTX PRO 4000 Blackwell SFF delivers performance indistinguishable from the RTX 4060 Ti family in this specific DirectX 12 test.

For the Intel Arc Pro B390, the absence of recorded benchmarks means the database cannot confirm any performance claims. The part exists with full specifications, an active production status, and a release date, but its average benchmark score is zero and its percentile rank is 50, a placeholder value that carries no comparative meaning without test results. Users seeking a workstation GPU with verified data should select the RTX PRO 4000 Blackwell SFF. Users constrained to integrated graphics, where the Arc Pro B390 operates as an IGP with no power connectors, may find it suitable for portable or embedded systems, but the database offers no measured evidence of its capabilities.

Where Each One Wins

The RTX PRO 4000 Blackwell SFF wins the only category that matters in the recorded data: benchmark performance. Its 3DMark Steel Nomad DX12 score of 2910 stands as the sole verified performance figure in this comparison. The Arc Pro B390 has zero wins recorded, zero benchmark entries, and no comparative scores.

The Arc Pro B390 wins in the category of physical integration. It is an IGP, meaning the graphics processor is integrated into the system package, requiring no slot width, no power connectors, and no dedicated memory. Its memory is system shared, its bus interface is IGP, and its display outputs are portable device dependent. This makes it a candidate for compact, low-power systems where a discrete card cannot fit. The RTX PRO 4000 Blackwell SFF, by contrast, is a dual-slot card measuring 167 mm in length, 69 mm in height, and 40 mm in width, with a PCIe 5.0 x8 interface and four mini-DisplayPort 2.1b outputs.

In raw throughput specifications, the RTX PRO 4000 Blackwell SFF holds decisive advantages. It delivers 24.05 TFLOPS FP32 performance versus 7.680 TFLOPS for the Arc Pro B390. Its pixel rate is 128.8 GPixel/s versus 60.00 GPixel/s, and its texture rate is 375.8 GTexel/s versus 120.0 GTexel/s. The NVIDIA part carries 8960 shading units, 280 texture mapping units, 96 ROPs, 70 RT cores, and 280 tensor cores, while the Intel part has 1536 shading units, 48 TMUs, 24 ROPs, and 12 RT cores. The RTX PRO 4000 also features 24 GB of GDDR7 memory on a 192-bit bus with 432.0 GB/s bandwidth, while the Arc Pro B390 relies entirely on system shared memory with system dependent bandwidth.

Architecture Differences

The two parts come from different manufacturers, different foundries, and different process nodes. The Intel Arc Pro B390 uses the Panther Lake chip built on Intel's Xe3-LPG architecture, part of the Arc Graphics-WM (Panther Lake) generation. It is fabricated on a 3 nm process at Intel's foundry. The NVIDIA RTX PRO 4000 Blackwell SFF uses the GB203 chip built on Blackwell 2.0 architecture, part of the Blackwell PRO W (x000) generation. It is fabricated on a 5 nm process at TSMC.

The NVIDIA part has a known transistor count of 45,600 million on a 378 mm² die, giving a transistor density of 120.6M per mm². The Intel part's transistor count, die size, and transistor density are all listed as unknown in the database.

Clock behavior differs substantially. The Arc Pro B390 has a base clock of 300 MHz and a boost clock of 2500 MHz. The RTX PRO 4000 Blackwell SFF has a base clock of 405 MHz and a boost clock of 1342 MHz. The Intel part boosts much higher, but the NVIDIA part compensates with far more execution resources.

Memory architecture is fundamentally different. The Arc Pro B390 uses system shared memory with a system dependent bus width and bandwidth, meaning its performance scales with the host system's memory configuration. The RTX PRO 4000 Blackwell SFF carries 24 GB of dedicated GDDR7 memory on a 192-bit bus with 432.0 GB/s bandwidth and a memory clock of 1125 MHz, 18 Gbps effective.

Feature sets show both parts support modern APIs. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The RTX PRO 4000 Blackwell SFF adds 280 tensor cores, which the Arc Pro B390 lacks entirely (its tensor core count is null). The NVIDIA part also has 70 RT cores versus 12 on the Intel part.

Power characteristics are notably different. The Arc Pro B390 has an 80 W TDP and requires no power connectors. The RTX PRO 4000 Blackwell SFF has a 70 W TDP, also requires no power connectors, but the database suggests a 250 W PSU for the system. The NVIDIA card is dual-slot, while the Intel part is an IGP with no slot footprint.

The release dates differ by several months. The RTX PRO 4000 Blackwell SFF was released on 2025-08-10, while the Arc Pro B390 was released on 2026-01-26. The NVIDIA part's predecessor is Workstation Ada, while the Intel part's predecessor is HD Graphics-WM.

Head-to-Head Benchmarks

The head-to-head benchmark section in the database contains no entries, and the win counts are zero for both parts. There is no direct comparative test data between the Intel Arc Pro B390 and the NVIDIA RTX PRO 4000 Blackwell SFF. The only benchmark result available is the RTX PRO 4000 Blackwell SFF's 3DMark Steel Nomad DX12 score of 2910.

Without head-to-head results, the most informative comparison comes from the RTX PRO 4000 Blackwell SFF's nearest rivals. The score of 2910 places it within a narrow band of cards: the GeForce RTX 4060 Ti 8 GB leads this group at 2913, just 0.1 percent higher. The Quadro P600 scores 2923, 0.4 percent higher. The GeForce RTX 4060 Ti 16 GB scores 2907, 0.1 percent lower. The GeForce RTX 4010 scores 2893, 0.6 percent lower. This cluster of scores across a 30-point range suggests the RTX PRO 4000 Blackwell SFF performs at the level of the RTX 4060 Ti family in this workload.

The specification gap between the two compared parts is enormous. The RTX PRO 4000 Blackwell SFF delivers 24.05 TFLOPS FP32, which is 3.1 times the 7.680 TFLOPS of the Arc Pro B390. Its pixel rate of 128.8 GPixel/s is 2.1 times the 60.00 GPixel/s of the Intel part. Its texture rate of 375.8 GTexel/s is 3.1 times the 120.0 GTexel/s of the Intel part. The NVIDIA card has 5.8 times more shading units (8960 versus 1536), 5.8 times more TMUs (280 versus 48), 4 times more ROPs (96 versus 24), and 5.8 times more RT cores (70 versus 12).

The most significant difference is memory. The RTX PRO 4000 Blackwell SFF has 24 GB of dedicated GDDR7 memory with 432.0 GB/s of bandwidth, while the Arc Pro B390 must share system memory with the host CPU and its bandwidth is entirely system dependent. For memory-intensive workstation workloads, the dedicated 24 GB pool with fixed bandwidth provides a consistent performance baseline that the Intel IGP cannot match.

Clock speeds tell a different story. The Arc Pro B390 boosts to 2500 MHz, nearly double the 1342 MHz boost clock of the RTX PRO 4000 Blackwell SFF. The Intel part also has a lower base clock at 300 MHz versus 405 MHz. The higher boost clock on the Intel part partially compensates for its fewer execution units, but the raw throughput figures show the NVIDIA part maintains a commanding lead despite its lower clock speed.

The process node difference favors Intel in theory: 3 nm versus 5 nm. However, the database records no efficiency benchmarks or power-per-performance metrics, so no conclusion can be drawn about the practical benefits of the smaller node. What the data does show is that the RTX PRO 4000 Blackwell SFF, with its larger transistor count of 45,600 million and die size of 378 mm², delivers the only verified performance result in this comparison.
