Intel Arc Pro B390 vs NVIDIA GeForce RTX 3050 A Mobile Comparison

Intel Arc Pro B390 and NVIDIA GeForce RTX 3050 A Mobile represent two distinct approaches to mobile graphics, one integrated and one discrete. The database records show the Intel part as an active, integrated processor from the Panther Lake generation, while the NVIDIA part is an end-of-life discrete mobile GPU based on the Ampere architecture. Their performance profiles, architectural designs, and production statuses differ substantially, leading to a clear separation in use-case suitability.

Where Each One Wins

The recorded benchmark data provides a clear picture of where each GPU excels. The NVIDIA GeForce RTX 3050 A Mobile has a substantial set of benchmark results in the database, including a PassMark G3D score of 11664, a PassMark GPU Compute score of 4419, and a Geekbench OpenCL score of 52998. These recorded measurements place the NVIDIA part at the 44th percentile of all GPUs, with an average benchmark score of 8746. The Intel Arc Pro B390, by contrast, has no recorded benchmark scores in the database, with an average benchmark score of 0 and a 50th percentile ranking. This means the Intel part wins in no measured performance test, while the NVIDIA part wins all recorded comparisons by default due to the absence of data for the Intel side.

The NVIDIA GPU also wins on the basis of having a complete, measurable performance profile. Its nearest rivals in the database include the NVIDIA GeForce GTX 460 v2 with an average score of 8743 and a delta of 0 percent, the NVIDIA Quadro P2200 at 8686 with a delta of 0.7 percent, the AMD Radeon R9 M265X at 8851 with a delta of -1.2 percent, and the AMD Radeon Pro WX 5100 at 8863 with a delta of -1.3 percent. These figures indicate the RTX 3050 A Mobile sits within a tight performance band, slightly ahead of the Quadro P2200 and marginally behind the two AMD parts. The Intel Arc Pro B390, without any benchmark entries, cannot be positioned against these rivals in the recorded data.

Architecture Differences

The two GPUs use fundamentally different architectures and manufacturing processes. The Intel Arc Pro B390 is built on the Xe3-LPG architecture, uses the Panther Lake chip, and is fabricated on Intel's 3 nm process node. The NVIDIA GeForce RTX 3050 A Mobile uses the Ampere architecture with the GA106 chip, fabricated on Samsung's 8 nm process. The Intel process node is smaller, which typically allows for higher transistor density and improved power efficiency, though the database records no transistor count or die size for the Intel part.

The NVIDIA GPU has recorded physical specifications. It contains 12,000 million transistors on a 276 mm² die, yielding a transistor density of 43.5 million per square millimeter. The Intel part lists transistors, die size, and transistor density as unknown. The Intel Arc Pro B390 is an integrated graphics processor, indicated by its slot width of IGP and bus interface of IGP, while the NVIDIA RTX 3050 A Mobile, despite also being listed with an IGP slot width, uses a PCIe 4.0 x8 bus interface, confirming its discrete nature. The Intel part has a TDP of 80 W, while the NVIDIA part draws 45 W, making the NVIDIA GPU the lower-power option despite being a discrete solution.

Shader and fixed-function unit counts also differ. The Intel Arc Pro B390 has 1536 shading units, 48 texture mapping units, 24 raster output pipelines, and 12 ray tracing cores. The NVIDIA GeForce RTX 3050 A Mobile has 1792 shading units, 56 TMUs, 32 ROPs, 14 ray tracing cores, and 56 tensor cores. The Intel part has no recorded tensor core count. The NVIDIA GPU therefore has more shading units, more TMUs, more ROPs, and more ray tracing cores, while also adding tensor cores that the Intel part does not list. Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Clock speeds show a major divergence. The Intel Arc Pro B390 has a base clock of 300 MHz and a boost clock of 2500 MHz, a wide range that reflects its integrated nature and power management. The NVIDIA part has a base clock of 1065 MHz and a boost clock of 1343 MHz, a much narrower range. Memory configuration also differs completely: the Intel part uses system shared memory with a system-dependent bus width and bandwidth, while the NVIDIA part has 4 GB of dedicated GDDR6 memory on a 128-bit bus with 192.0 GB/s of bandwidth.

Head-to-Head Benchmarks

Direct head-to-head benchmark comparisons are not possible because the Intel Arc Pro B390 has no recorded benchmark scores in the database. The only measurable performance data comes from the NVIDIA GeForce RTX 3050 A Mobile. Its PassMark DirectX 11 score of 94 is its highest API-specific result, followed by PassMark DirectX 9 at 152, PassMark DirectX 10 at 61, and PassMark DirectX 12 at 55. The PassMark G2D score of 526 reflects 2D graphics performance, while the PassMark G3D score of 11664 is the primary 3D performance metric. The PassMark GPU Compute score of 4419 measures compute workloads, and the Geekbench OpenCL score of 52998 provides an additional cross-platform compute measurement.

The NVIDIA part's average benchmark score of 8746 positions it just above the NVIDIA GeForce GTX 460 v2 at 8743, a delta of 0 percent. It sits 0.7 percent ahead of the NVIDIA Quadro P2200 at 8686. Against the AMD Radeon R9 M265X at 8851, the RTX 3050 A Mobile is 1.2 percent behind, and against the AMD Radeon Pro WX 5100 at 8863, it is 1.3 percent behind. These deltas show a GPU that is competitive with older workstation and mid-range parts, clustered within a narrow 2 percent performance window across its nearest recorded rivals.

The Intel Arc Pro B390, with its theoretical peak rates of 7.680 TFLOPS FP32 and 15.36 TFLOPS FP16 at a 2:1 ratio, shows higher raw compute ratings than the NVIDIA part's 4.813 TFLOPS FP32 and 4.813 TFLOPS FP16 at a 1:1 ratio. The Intel part also has higher pixel and texture rates, with 60.00 GPixel/s and 120.0 GTexel/s respectively, versus the NVIDIA part's 42.98 GPixel/s and 75.21 GTexel/s. However, these are specification-derived figures, not measured benchmark results, and the database contains no test scores to confirm the Intel part's real-world performance.

Specification Differences

The two GPUs differ across nearly every recorded specification. The Intel Arc Pro B390 uses the Xe3-LPG architecture with a Panther Lake chip on a 3 nm Intel process, while the NVIDIA GeForce RTX 3050 A Mobile uses Ampere with a GA106 chip on an 8 nm Samsung process. Transistor count is unknown for Intel but 12,000 million for NVIDIA, and die size is unknown for Intel but 276 mm² for NVIDIA. The Intel part has a 300 MHz base clock and 2500 MHz boost clock, while the NVIDIA part has a 1065 MHz base clock and 1343 MHz boost clock. Memory is system shared for Intel versus 4 GB GDDR6 for NVIDIA. Shading units are 1536 versus 1792, TMUs are 48 versus 56, ROPs are 24 versus 32, and ray tracing cores are 12 versus 14. The NVIDIA part has 56 tensor cores; the Intel part lists none. Pixel rate is 60.00 GPixel/s for Intel versus 42.98 GPixel/s for NVIDIA, and texture rate is 120.0 GTexel/s versus 75.21 GTexel/s. FP32 compute is 7.680 TFLOPS versus 4.813 TFLOPS, and FP16 is 15.36 TFLOPS at 2:1 versus 4.813 TFLOPS at 1:1. TDP is 80 W versus 45 W.

Both share the same API support, display outputs, and power connector configuration.

The Verdict

The recorded data supports a clear division of roles. The NVIDIA GeForce RTX 3050 A Mobile is the only one of the two with measured performance data, and its benchmark scores, including a PassMark G3D score of 11664 and a Geekbench OpenCL score of 52998, place it in a competitive band near the NVIDIA GeForce GTX 460 v2 and NVIDIA Quadro P2200. Its 45 W TDP and dedicated 4 GB GDDR6 memory make it a suitable option for portable devices where a discrete GPU with established, measurable performance is required. The Intel Arc Pro B390, with no recorded benchmarks, cannot be evaluated on measured performance. Its higher theoretical FP32 rate of 7.680 TFLOPS, 80 W TDP, and integrated system-shared memory design indicate a different target: a newer, active integrated solution from the Panther Lake generation that relies on shared system resources. Users requiring confirmed performance data should rely on the NVIDIA part, while the Intel part remains an unverified specification sheet entry in the database.
