Intel Arc Pro B390 vs NVIDIA GeForce RTX 4050 Mobile Comparison

Head-to-Head Benchmarks

The recorded data shows a clear competitive gap between these two mobile graphics solutions, though direct head-to-head benchmark comparisons are not available in the database. The Intel Arc Pro B390 has no stored benchmark scores, while the NVIDIA GeForce RTX 4050 Mobile has a full suite of nine recorded benchmark results. This asymmetry means the analysis must rely on the RTX 4050 Mobile's absolute scores and its percentile standing relative to all GPUs.

The RTX 4050 Mobile's average benchmark score is 19049, placing it in the 63rd percentile of all GPUs in the database. Its nearest rivals provide context: the AMD Radeon RX 6600 scores 19036 with a delta of 0.1%, the NVIDIA Quadro K6000 scores 19030 with a delta of 0.1%, the NVIDIA Tesla K20m scores 19089 with a delta of -0.2%, and the NVIDIA RTX 2000 Ada Generation scores 18954 with a delta of 0.5%. These deltas indicate the RTX 4050 Mobile sits within a tightly packed performance cluster, essentially matching the RX 6600 while trailing the Tesla K20m by a negligible margin.

Looking at individual test scores, the RTX 4050 Mobile delivers 74748 in Geekbench OpenCL and 75235 in Geekbench Vulkan. The Passmark suite shows a more varied picture: DirectX 10 score of 79, DirectX 11 score of 130, DirectX 12 score of 61, DirectX 9 score of 184, G2D score of 633, G3D score of 14423, and GPU compute score of 5947. The G3D score of 14423 dominates the average, suggesting the card is strongest in traditional 3D rendering workloads rather than compute-heavy tasks, which the GPU compute score of 5947 confirms as a relative weakness.

For the Intel Arc Pro B390, the absence of benchmark data means the database records zero wins for either side in head-to-head comparisons. The Arc Pro B390's percentile Vs All GPUs is 50, placing it at the median, but this is a placeholder percentile rather than a measured result. The practical takeaway: the RTX 4050 Mobile is a measured performer with documented scores, while the Arc Pro B390 has no recorded performance evidence in this database.

Architecture Differences

The two GPUs represent fundamentally different design philosophies. The Intel Arc Pro B390 uses the Xe3-LPG architecture built on Panther Lake silicon, manufactured on a 3 nm process at Intel's own foundry. The NVIDIA GeForce RTX 4050 Mobile uses Ada Lovelace architecture on the AD107 chip, manufactured on a 5 nm process at TSMC. The process node difference is significant: the Intel part uses a smaller 3 nm node, though transistor counts and die sizes for the Intel chip are listed as unknown. The RTX 4050 Mobile contains 18,900 million transistors on a 159 mm² die, yielding a transistor density of 118.9M per mm².

Clock behavior differs sharply. The Arc Pro B390 has a base clock of 300 MHz and a boost clock of 2500 MHz, a wide boost range that suggests aggressive power management. The RTX 4050 Mobile runs at a base of 1455 MHz and boosts to 1755 MHz, a much narrower range. Memory configurations are entirely different as well. The Arc Pro B390 uses system shared memory with system shared type and bus width, with bandwidth described as system dependent. The RTX 4050 Mobile has 6 GB of dedicated GDDR6 memory on a 96-bit bus with 192.0 GB/s bandwidth and an effective memory clock of 16 Gbps.

Compute resources show a substantial gap. The Arc Pro B390 has 1536 shading units, 48 texture mapping units, 24 raster output units, and 12 ray tracing cores. The RTX 4050 Mobile has 2560 shading units, 80 TMUs, 48 ROPs, 20 RT cores, and 80 tensor cores. The Arc Pro B390 lists no tensor cores, which is a notable omission for AI-accelerated workloads. Raw throughput figures reflect these differences: the Arc Pro B390 delivers 7.680 TFLOPS FP32 and 15.36 TFLOPS FP16 with a 2:1 ratio, while the RTX 4050 Mobile delivers 8.986 TFLOPS FP32 and 8.986 TFLOPS FP16 with a 1:1 ratio. The Intel part has a clear FP16 advantage due to its 2:1 rate, while NVIDIA maintains parity between FP16 and FP32.

Pixel and texture rates tell a similar story. The Arc Pro B390 achieves 60.00 GPixel/s and 120.0 GTexel/s, while the RTX 4050 Mobile reaches 84.24 GPixel/s and 140.4 GTexel/s. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API feature parity exists at the specification level.

Power envelopes differ significantly. The Arc Pro B390 has an 80 W TDP, while the RTX 4050 Mobile has a 50 W TDP. Both are integrated into portable devices with no power connectors and IGP slot widths, but the RTX 4050 Mobile uses a PCIe 4.0 x8 bus interface, whereas the Arc Pro B390 uses an IGP bus interface. Display outputs for both are listed as portable device dependent.

Where Each One Wins

The data supports distinct use-case strengths. The RTX 4050 Mobile wins on raw rasterization throughput, evidenced by its higher pixel rate of 84.24 GPixel/s versus 60.00 GPixel/s, and its texture rate of 140.4 GTexel/s versus 120.0 GTexel/s. Its shading unit count of 2560 versus 1536 gives it a clear advantage in parallel workload execution. The dedicated 6 GB GDDR6 memory with 192.0 GB/s bandwidth avoids the system memory contention that the Arc Pro B390's shared memory configuration could encounter.

The Arc Pro B390 wins on FP16 compute. Its 15.36 TFLOPS FP16 throughput, achieved through a 2:1 ratio, doubles its FP32 rate of 7.680 TFLOPS. The RTX 4050 Mobile's FP16 performance matches its FP32 at 8.986 TFLOPS, meaning the Intel part has a theoretical 71% advantage in FP16 workloads. This matters for applications that leverage half-precision math, such as certain machine learning inference tasks and image processing pipelines.

The RTX 4050 Mobile also has the tensor core advantage with 80 tensor cores, while the Arc Pro B390 has none listed. This makes the NVIDIA part the more complete package for AI-accelerated features, despite the Intel part's higher raw FP16 throughput. The RTX 4050 Mobile's 20 RT cores versus 12 on the Intel part also gives it an edge in ray-traced workloads.

Power efficiency favors the RTX 4050 Mobile based on the recorded specifications. The NVIDIA part delivers higher pixel rate, texture rate, and FP32 throughput while drawing 50 W, compared to the Intel part's 80 W for lower rates. The RTX 4050 Mobile achieves 8.986 TFLOPS FP32 at 50 W versus 7.680 TFLOPS at 80 W, a clear efficiency advantage.

The Verdict

The recorded data points to the NVIDIA GeForce RTX 4050 Mobile as the stronger performer in most measurable categories. It has a higher average benchmark score of 19049, a higher percentile ranking of 63 versus 50, more shading units, more RT cores, tensor cores, and a larger FP32 throughput at 8.986 TFLOPS versus 7.680 TFLOPS. Its pixel and texture rates are higher despite a lower TDP of 50 W versus 80 W. The dedicated 6 GB GDDR6 memory with 192.0 GB/s bandwidth provides a concrete memory advantage over the Intel part's system shared configuration.

The Intel Arc Pro B390 claims only one clear specification victory: FP16 throughput at 15.36 TFLOPS versus 8.986 TFLOPS for NVIDIA. This makes it a candidate for workloads that heavily use half-precision math, though the absence of tensor cores limits its AI acceleration capabilities. The Intel part also uses a smaller 3 nm process node versus 5 nm, which could imply better transistor-level efficiency, but the recorded power figure of 80 W suggests that efficiency does not translate into a power advantage.

The release dates tell a story of different market positions. The RTX 4050 Mobile launched on 2023-01-02 and has an established successor in the GeForce 50 Mobile, while the Arc Pro B390 launched on 2026-01-26 and is actively in production. Buyers choosing between these two in a portable device should weigh the RTX 4050 Mobile's measured benchmark dominance and lower power draw against the Arc Pro B390's FP16 capability and newer process node. The database's benchmark evidence supports the NVIDIA part for general graphics, ray tracing, and compute workloads. The Intel part remains an unproven quantity with no recorded scores, making its real-world performance a matter of specification extrapolation rather than demonstrated results.
