Intel Arc Pro B390 vs NVIDIA RTX PRO 5000 Blackwell Comparison

Head-to-Head Benchmarks

The recorded data contains no shared benchmark runs between the Intel Arc Pro B390 and the NVIDIA RTX PRO 5000 Blackwell. The Intel part has no benchmark entries, while the NVIDIA card carries three scores: 9,579.5 in 3DMark Steel Nomad DX12, 254,116 in Geekbench OpenCL, and 282,631 in Geekbench Vulkan. Without overlapping tests, the database cannot produce a direct performance delta between these two products. The Intel Arc Pro B390 sits at the 50th percentile among all GPUs with an average benchmark score of zero, meaning no measured workloads have been recorded for it. The RTX PRO 5000 Blackwell ranks at the 98th percentile with an average score of 182,109.

The NVIDIA card's nearest rivals in the database are all data center and workstation parts. The A100 SXM4 80 GB scores 183,725, which is 0.9% higher than the RTX PRO 5000 Blackwell. The RTX 5000 Ada Generation scores 184,664, 1.4% higher. The GeForce RTX 4090 D scores 178,050, which is 2.3% lower. The A100 SXM4 40 GB scores 187,147, 2.7% higher. These deltas place the RTX PRO 5000 Blackwell in a tight cluster where the largest recorded gap is under three percentage points.

The Intel Arc Pro B390 has no nearest rival entries, no wins, and no losses in head-to-head comparisons. Its zero average benchmark score reflects an absence of data rather than a measured performance level. The NVIDIA card, by contrast, has three benchmark results that indicate strong compute throughput, particularly in API-level tests where Geekbench Vulkan exceeds OpenCL by 28,515 points, roughly 11% higher within its own recorded results.

The Verdict

The data supports a clear split. For workloads where the RTX PRO 5000 Blackwell has recorded scores, it occupies the 98th percentile, indicating it outperforms nearly all other GPUs in the database. Its 48 GB GDDR7 memory, 1.34 TB/s bandwidth, and 66.94 TFLOPS FP32 throughput place it firmly in the high-end workstation segment. The Intel Arc Pro B390, with no benchmark scores, cannot be positioned relative to any rival. Its 50th percentile is a default ranking for unmeasured parts.

Users who need a dedicated, high-throughput GPU with proven benchmark results should look at the RTX PRO 5000 Blackwell. Users constrained to an integrated graphics solution, where the Intel part operates as an IGP with system-shared memory, would select the Arc Pro B390 only if the system form factor requires no external power connectors and no expansion slot. The RTX PRO 5000 Blackwell requires a 700 W suggested PSU, a 16-pin power connector, and a dual-slot PCIe 5.0 x16 interface. The Intel part uses no power connectors and occupies the IGP slot width. These are different product categories, and the benchmark gap is a function of that division.

Architecture Differences

The Intel Arc Pro B390 uses the Panther Lake chip with Xe3-LPG architecture, built on a 3 nm process at Intel. The NVIDIA RTX PRO 5000 Blackwell uses the GB202 chip with Blackwell 2.0 architecture, built on a 5 nm process at TSMC. The Intel part integrates 1,536 shading units, 48 texture mapping units, 24 raster output units, and 12 ray tracing cores. The NVIDIA part packs 14,080 shading units, 440 TMUs, 160 ROPs, 110 RT cores, and 440 tensor cores.

The RTX PRO 5000 Blackwell has 92,200 million transistors on a 750 mm² die, with a transistor density of 122.9 million per mm². The Intel part's transistor count and die size are listed as unknown. The NVIDIA card uses GDDR7 memory with a 384-bit bus and 1.34 TB/s bandwidth. The Intel part shares system memory with the host CPU, so its bus width and bandwidth are system dependent.

The RTX PRO 5000 Blackwell supports FP16 at a 1:1 ratio with FP32, both at 66.94 TFLOPS. The Intel Arc Pro B390 runs FP16 at 15.36 TFLOPS with a 2:1 ratio relative to its 7.680 TFLOPS FP32 rate. The NVIDIA card also includes tensor cores, which the Intel part does not list. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Specification Differences

The clock behavior differs substantially. The Intel Arc Pro B390 has a 300 MHz base clock and a 2,500 MHz boost clock. The NVIDIA RTX PRO 5000 Blackwell has a 1,740 MHz base clock and a 2,377 MHz boost clock. Memory clocks are not comparable because the Intel part uses system shared memory with no dedicated memory clock, while the NVIDIA card runs at 1,750 MHz with 28 Gbps effective data rate.

Memory capacity is a major differentiator: the Intel part has no dedicated memory, while the NVIDIA card has 48 GB GDDR7. The Intel part's pixel rate is 60.00 GPixel/s versus 380.3 GPixel/s for NVIDIA. Texture rates are 120.0 GTexel/s versus 1,045.9 GTexel/s. Power draw is 80 W for Intel and 300 W for NVIDIA. The Intel part is an IGP with no power connectors; the NVIDIA card is dual-slot with a single 16-pin connector and a 700 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 and 4x DisplayPort 2.1b for NVIDIA. The NVIDIA card has physical dimensions of 267 mm length, 111 mm height, and 40 mm width. The Intel part has no listed dimensions. Release dates differ: Intel launched on 2026-01-26, NVIDIA on 2025-03-17. The Intel predecessor is HD Graphics-WM; the NVIDIA predecessor is Workstation Ada. The launch MSRP for the NVIDIA RTX PRO 5000 Blackwell is 5,099 USD; the Intel part has no launch MSRP listed.

Where Each One Wins

The NVIDIA RTX PRO 5000 Blackwell wins in every measured benchmark category. Its Geekbench Vulkan score of 282,631 is the highest recorded result for either product, and its OpenCL score of 254,116 indicates strong compute performance across API boundaries. The 3DMark Steel Nomad DX12 score of 9,579.5 confirms rasterization capability in a modern DX12 workload. The 98th percentile ranking places it above nearly all GPUs in the database.

The Intel Arc Pro B390 wins in power efficiency and integration. Its 80 W TDP is far lower than the NVIDIA card's 300 W, and its IGP form factor requires no slot, no power connector, and no dedicated PSU. For ultraportable devices where the display output is portable device dependent, the Intel part is the only viable option among the two. The 3 nm process node indicates a newer manufacturing technology, though the NVIDIA part's 5 nm node still delivers far higher transistor density per mm² due to its larger die and higher transistor count.

The RTX PRO 5000 Blackwell also wins in memory capacity and bandwidth. Its 48 GB GDDR7 pool with 1.34 TB/s bandwidth is a workstation-class configuration. The Intel part's system shared memory makes its bandwidth dependent on the host platform, which the database lists as system dependent. For texture-heavy workloads, the NVIDIA card's 1,045.9 GTexel/s rate dwarfs the Intel part's 120.0 GTexel/s. For pixel throughput, the NVIDIA card's 380.3 GPixel/s is more than six times the Intel part's 60.00 GPixel/s.

The Intel Arc Pro B390 has the later release date of 2026-01-26, while the NVIDIA card arrived on 2025-03-17. However, the NVIDIA part has a launch MSRP of 5,099 USD, and the Intel part has no listed MSRP, which suggests it is bundled with a processor rather than sold standalone. In terms of production status, both are listed as active. The Intel part's predecessor is HD Graphics-WM, while the NVIDIA card's predecessor is Workstation Ada. Neither has a listed successor.
