Intel Arc B390 vs NVIDIA GeForce RTX 3050 A Mobile Comparison

Head-to-Head Benchmarks

The recorded data for the Intel Arc B390 contains a single benchmark result, the 3DMark Steel Nomad DX12 test, with a score of 1482. The NVIDIA GeForce RTX 3050 A Mobile has a broader set of recorded measurements, including Geekbench OpenCL and multiple Passmark tests. Direct head-to-head comparisons between the two are not available in the database, so the analysis relies on the separate benchmark collections and aggregate percentile scores.

The Intel Arc B390 places at the 9th percentile across all GPUs in the database. Its nearest rivals are all older, low-end discrete parts: the NVIDIA GeForce GT 520MX (average score 1463, a 1.3% gap), the NVIDIA GeForce 800M (1460, 1.5% gap), the NVIDIA GeForce GT 625 OEM (1446, 2.5% gap), and the NVIDIA GeForce GT 710 (1443, 2.7% gap). The Arc B390's average benchmark score of 1482 sits just 1.3% above the GT 520MX, which indicates that its single recorded result places it in a very low performance tier, roughly comparable to decade-old entry-level discrete graphics.

The NVIDIA GeForce RTX 3050 A Mobile, in contrast, records a 44th percentile position across all GPUs. Its average benchmark score is 8746, which is dramatically higher than the Arc B390's 1482. The nearest rivals for the RTX 3050 A Mobile are substantially stronger parts: the NVIDIA GeForce GTX 460 v2 (8743, 0% difference), the NVIDIA Quadro P2200 (8686, 0.7% difference), the AMD Radeon R9 M265X (8851, -1.2% difference), and the AMD Radeon Pro WX 5100 (8863, -1.3% difference). The RTX 3050 A Mobile sits within a narrow band around those scores, showing that its aggregate performance is roughly five to six times higher than the Arc B390's single recorded data point.

The Geekbench OpenCL score for the RTX 3050 A Mobile is 52998, while its Passmark G3D score is 11664. The Passmark GPU Compute score is 4419. The Arc B390 has no equivalent OpenCL or Passmark entries in the database, so direct cross-test comparisons are not possible. Still, the percentile gap (9 vs 44) and the average score gap (1482 vs 8746) are decisive. The data shows that the RTX 3050 A Mobile occupies a mid-range mobile performance tier, while the Arc B390, based on its benchmark, sits near the bottom of the database's GPU rankings.

Architecture Differences

The Intel Arc B390 uses the Panther Lake chip with the Xe3-LPG architecture, belonging to the Arc Graphics-M (Panther Lake) generation. It is built on a 3 nm process at Intel's foundry. The NVIDIA GeForce RTX 3050 A Mobile uses the GA106 chip with the Ampere architecture, belonging to the GeForce 30 Mobile generation, and is built on an 8 nm process at Samsung.

The transistor counts and die sizes differ substantially. The RTX 3050 A Mobile has 12,000 million transistors on a 276 mm² die, with a transistor density of 43.5M per mm². The Arc B390's transistor count and die size are listed as unknown, so no direct comparison is possible there. The process node difference (3 nm vs 8 nm) suggests a significant manufacturing generation gap, but the database does not provide transistor density for the Arc B390 to confirm the scaling.

Memory architecture is a major divergence. The Arc B390 uses system shared memory, with a system dependent bandwidth and no dedicated VRAM. The RTX 3050 A Mobile has 4 GB of GDDR6 memory on a 128-bit bus, providing 192.0 GB/s of bandwidth. This means the RTX 3050 A Mobile has a fixed, dedicated memory pool, while the Arc B390 relies on the host system's memory, which can vary.

The ray tracing and compute units also differ. The Arc B390 has 12 ray tracing cores and no listed tensor cores. The RTX 3050 A Mobile has 14 ray tracing cores and 56 tensor cores, which indicates a more complete feature set for AI-accelerated workloads. The Arc B390's shading unit count is 1536, while the RTX 3050 A Mobile has 1792, and the TMU counts are 48 vs 56 respectively. The ROP counts are 24 for the Arc B390 and 32 for the RTX 3050 A Mobile.

API support is identical across the two: both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The bus interfaces differ: the Arc B390 uses an IGP (integrated graphics processor) interface, while the RTX 3050 A Mobile uses PCIe 4.0 x8. Both are listed as IGP slot width, with portable device dependent display outputs and no power connectors.

The Arc B390 has a higher base clock, boost clock, pixel rate, texture rate, FP32, and FP16 performance on paper. The RTX 3050 A Mobile has a higher memory bandwidth, more shading units, more TMUs, more ROPs, more RT cores, and tensor cores that the Arc B390 lacks. The TDP is higher for the Arc B390 (80 W vs 45 W), which is notable given that both are listed as IGP-class parts.

Where Each One Wins

The Intel Arc B390 wins in raw compute throughput metrics from the specification sheet. Its FP32 performance of 7.680 TFLOPS is 1.6 times the RTX 3050 A Mobile's 4.813 TFLOPS. Its FP16 performance of 15.36 TFLOPS (2:1 ratio) is more than three times the RTX 3050 A Mobile's 4.813 TFLOPS (1:1 ratio). The pixel rate of 60.00 GPixel/s exceeds the RTX 3050 A Mobile's 42.98 GPixel/s, and the texture rate of 120.0 GTexel/s exceeds 75.21 GTexel/s. These figures suggest the Arc B390 is designed for higher throughput in shader-heavy workloads, despite its lower benchmark percentile.

The NVIDIA GeForce RTX 3050 A Mobile wins in memory capacity and bandwidth. It has 4 GB of dedicated GDDR6 memory with 192.0 GB/s bandwidth, while the Arc B390 relies on system shared memory with system dependent bandwidth. The RTX 3050 A Mobile also has a higher shading unit count (1792 vs 1536), more TMUs (56 vs 48), more ROPs (32 vs 24), more RT cores (14 vs 12), and 56 tensor cores compared to none listed for the Arc B390. Its bus interface is PCIe 4.0 x8, which is a discrete connection, versus the Arc B390's IGP interface.

In terms of measured benchmarks, the RTX 3050 A Mobile is the clear winner. Its average score of 8746 puts it in the 44th percentile, while the Arc B390's 1482 sits in the 9th percentile. The RTX 3050 A Mobile's nearest rivals are much stronger parts (GTX 460 v2, Quadro P2200, R9 M265X, Pro WX 5100), all within 1.3% of its score. The Arc B390's rivals are all low-end legacy GPUs (GT 520MX, 800M, GT 625 OEM, GT 710). The RTX 3050 A Mobile also has a broader benchmark suite recorded, including OpenCL and multiple Passmark tests, whereas the Arc B390 has only a single DX12 test.

The production status favors the Arc B390, which is Active, while the RTX 3050 A Mobile is End-of-life. The release date for the Arc B390 is later (2026-01-26 vs 2023-12-31), which indicates a newer product. The Arc B390 also has a lower base clock (300 MHz vs 1065 MHz) but a much higher boost clock (2500 MHz vs 1343 MHz), which points to a wider dynamic clock range.

The Verdict

Based on the recorded data, the NVIDIA GeForce RTX 3050 A Mobile is the stronger performer in aggregate benchmarks. Its average score of 8746 versus the Arc B390's 1482, combined with a 44th versus 9th percentile ranking, shows a substantial performance gap. The RTX 3050 A Mobile also has dedicated memory with 192.0 GB/s bandwidth, tensor cores for AI workloads, and a higher count of shading units, TMUs, ROPs, and RT cores. For any workload that relies on memory bandwidth, ray tracing, or tensor operations, the data clearly favors the RTX 3050 A Mobile.

The Intel Arc B390 offers higher theoretical compute rates: 7.680 TFLOPS FP32, 15.36 TFLOPS FP16, 60.00 GPixel/s pixel rate, and 120.0 GTexel/s texture rate. These specification advantages suggest the Arc B390 is optimized for compute-heavy shader workloads rather than memory-bound tasks. It is also a newer, active product with a 3 nm process node, whereas the RTX 3050 A Mobile is end-of-life on an 8 nm node.

The choice depends on the use case. For gaming and general mobile graphics, the RTX 3050 A Mobile's dedicated VRAM, higher benchmark scores, and wider test coverage make it the safer pick. For raw FP32 or FP16 compute, the Arc B390's specification sheet indicates higher throughput, though its single benchmark result does not confirm this in practice. The data shows no recorded head-to-head wins for either GPU, so the verdict rests on the aggregate scores and the specification differences. The RTX 3050 A Mobile is the proven performer; the Arc B390 is the newer part with higher peak compute rates but unverified real-world results beyond one DX12 test.
