Intel Arc Pro B390 vs NVIDIA GeForce RTX 5090 Mobile Comparison

Head-to-Head Benchmarks

The recorded data shows no direct head-to-head benchmark results exist between the Intel Arc Pro B390 and the NVIDIA GeForce RTX 5090 Mobile. The Intel Arc Pro B390 has zero recorded benchmark scores in the database, while the NVIDIA GeForce RTX 5090 Mobile has ten individual test results. This asymmetry makes a direct numerical comparison impossible, but the available data for the RTX 5090 Mobile provides a reference frame for interpreting its performance tier.

The RTX 5090 Mobile delivers a 3DMark Steel Nomad DX12 score of 5871, which places it in the upper portion of the database. Its Geekbench OpenCL result of 201834 and Vulkan result of 198405 indicate strong compute performance across different API environments. Passmark results show a G3D score of 30034, a GPU Compute score of 13401, and a G2D score of 1057. The DirectX 9, 10, 11, and 12 scores are 324, 183, 269, and 138 respectively.

The RTX 5090 Mobile holds an average benchmark score of 45152 and sits at the 84th percentile against all GPUs in the database. Its nearest rivals in the database include the AMD Radeon Pro 5500 XT with an average score of 45384, which is 0.5% higher than the RTX 5090 Mobile, and the NVIDIA GeForce RTX 4070 Ti with an average score of 44795, which is 0.8% lower. The Intel Arc A730M scores 45592, putting it 1% above the RTX 5090 Mobile, while the NVIDIA RTX 5880 Ada Generation scores 45972, which is 1.8% higher.

These narrow deltas against its nearest rivals suggest the RTX 5090 Mobile clusters tightly with a group of high-end GPUs. The data indicates that moving from the RTX 5090 Mobile to the RTX 5880 Ada Generation results in only a 1.8% average score improvement, while the Arc A730M edges it by just 1%. The Intel Arc Pro B390, with no benchmark scores recorded, cannot be placed within this hierarchy using measured results alone.

Architecture Differences

The Intel Arc Pro B390 uses the Panther Lake chip with Xe3-LPG architecture, built on a 3 nm process at Intel's foundry. The NVIDIA GeForce RTX 5090 Mobile uses the GB203 chip with Blackwell 2.0 architecture, fabricated on a 5 nm process at TSMC. The process node difference is significant: the Intel part uses a more advanced 3 nm node, while the NVIDIA part uses a 5 nm node.

The transistor counts diverge sharply. The Intel Arc Pro B390 lists its transistor count as unknown, while the NVIDIA GeForce RTX 5090 Mobile contains 45,600 million transistors on a 378 mm² die, giving a transistor density of 120.6M per mm². The Intel part's die size is also unknown, so a direct density comparison is not possible from the recorded data.

Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The shading unit counts differ substantially: the Intel Arc Pro B390 has 1536 shading units, while the RTX 5090 Mobile has 10496. Texture mapping units number 48 on the Intel part versus 328 on the NVIDIA part. Raster operation units are 24 versus 112. Ray tracing cores are 12 on the Intel part versus 82 on the NVIDIA part. The RTX 5090 Mobile also includes 328 tensor cores, while the Intel Arc Pro B390 has no tensor core count listed.

The Intel Arc Pro B390 uses a 2:1 FP16 ratio, delivering 15.36 TFLOPS of FP16 performance versus 7.680 TFLOPS of FP32. The RTX 5090 Mobile has a 1:1 FP16 ratio, delivering 31.80 TFLOPS for both FP16 and FP32. This indicates the Intel part splits its compute resources for FP16 work, while the NVIDIA part maintains full-rate FP16.

Specification Differences

The process node differs: the Intel Arc Pro B390 uses 3 nm, while the NVIDIA GeForce RTX 5090 Mobile uses 5 nm. The foundry also differs, with Intel listed for the Arc Pro B390 and TSMC for the RTX 5090 Mobile.

Clock speeds show a notable divergence. The Intel Arc Pro B390 has a base clock of 300 MHz and a boost clock of 2500 MHz. The RTX 5090 Mobile has a base clock of 990 MHz and a boost clock of 1515 MHz. The Intel part has a much lower base clock but a significantly higher boost clock. Memory clocks are listed as system shared for the Intel part, while the RTX 5090 Mobile runs at 1750 MHz with 28 Gbps effective.

Memory configuration differs completely. The Intel Arc Pro B390 uses system shared memory with a system-dependent bandwidth. The RTX 5090 Mobile has 24 GB of GDDR7 memory on a 256-bit bus with 896.0 GB/s of bandwidth.

Power consumption figures differ, with the Intel Arc Pro B390 rated at 80 W and the RTX 5090 Mobile rated at 95 W. Both use an IGP slot width and have no power connectors listed. The bus interface differs: the Intel part uses IGP, while the RTX 5090 Mobile uses PCIe 5.0 x16.

The Intel Arc Pro B390 has a texture rate of 120.0 GTexel/s and a pixel rate of 60.00 GPixel/s. The RTX 5090 Mobile has a texture rate of 496.9 GTexel/s and a pixel rate of 169.7 GPixel/s.

The Intel part's predecessor is listed as HD Graphics-WM, while the RTX 5090 Mobile's predecessor is GeForce 40 Mobile. The Intel Arc Pro B390 has no launch MSRP recorded, and neither does the RTX 5090 Mobile.

The Verdict

The recorded data indicates that the NVIDIA GeForce RTX 5090 Mobile is a high-performance mobile GPU with measured benchmark results across multiple test suites. Its 84th percentile ranking and average score of 45152 place it in the upper tier of the database. The Intel Arc Pro B390 has no recorded benchmark scores, which means its performance cannot be quantified from the database at this time.

The RTX 5090 Mobile's compute specifications align with its benchmark standing. Its FP32 throughput of 31.80 TFLOPS, 896.0 GB/s of memory bandwidth, and 10496 shading units support its position near rivals like the AMD Radeon Pro 5500 XT and NVIDIA RTX 5880 Ada Generation, all within 1.8% of each other in average score.

The Intel Arc Pro B390 presents a different profile. Its 80 W TDP, system shared memory, and 7.680 TFLOPS of FP32 suggest a different performance class, but without benchmark data, the database cannot confirm how it compares to the RTX 5090 Mobile. Its 50th percentile ranking is the only positional data available, and that is not derived from measured scores. Users seeking a GPU with confirmed high-end performance would look to the RTX 5090 Mobile based on the available evidence.

Where Each One Wins

The NVIDIA GeForce RTX 5090 Mobile wins in every category where measured data exists. Its benchmark suite covers DirectX 9 through 12, OpenCL, Vulkan, G2D, G3D, and GPU compute workloads. The highest recorded scores are 201834 in Geekbench OpenCL, 198405 in Geekbench Vulkan, and 30034 in Passmark G3D. These results position it as a capable performer across both graphics and compute applications.

The Intel Arc Pro B390 cannot claim any benchmark wins because no benchmark results are recorded. Its specification sheet does indicate strengths in certain areas. The 3 nm process node is the most advanced among the two, and its boost clock of 2500 MHz is substantially higher than the RTX 5090 Mobile's 1515 MHz. The 80 W TDP is lower than the RTX 5090 Mobile's 95 W, which could matter for power-constrained systems, though the database provides no efficiency metrics to confirm actual power draw.

For raw throughput metrics, the RTX 5090 Mobile leads in FP32 (31.80 TFLOPS versus 7.680 TFLOPS), pixel rate (169.7 GPixel/s versus 60.00 GPixel/s), texture rate (496.9 GTexel/s versus 120.0 GTexel/s), memory bandwidth (896.0 GB/s versus system dependent), and ray tracing cores (82 versus 12). The Intel Arc Pro B390 leads in process node (3 nm versus 5 nm) and boost clock (2500 MHz versus 1515 MHz), but these specification advantages do not translate into measured performance data in the database.

The RTX 5090 Mobile also holds the advantage in memory capacity with 24 GB of dedicated GDDR7, versus the Intel part's system shared memory. The PCIe 5.0 x16 interface on the RTX 5090 Mobile provides a conventional discrete GPU connection, while the Intel part relies on IGP integration. The database records the RTX 5090 Mobile as active in production with a release date of 2025-03-26, and the Intel Arc Pro B390 as active with a release date of 2026-01-26.
