NVIDIA GeForce RTX 3050 A Mobile vs NVIDIA Rubin GPU Comparison

Head-to-Head Benchmarks

The recorded data presents an unusual comparison: the GeForce RTX 3050 A Mobile has a full suite of benchmark results, while the Rubin GPU has no recorded benchmark scores at all. The database shows the RTX 3050 A Mobile achieving 52,998 in Geekbench OpenCL, 11,664 in Passmark G3D, and 4,419 in Passmark GPU Compute. Its Passmark DirectX scores range from 55 in DirectX 12 to 152 in DirectX 9, with DirectX 10 at 61 and DirectX 11 at 94. The 2D score sits at 526.

The Rubin GPU, by contrast, has zero recorded entries across all benchmark tests. Its average benchmark score is listed as 0, and it has no nearest rivals in the database. This absence of measurable data means no direct head-to-head comparison can be constructed from actual test results. The RTX 3050 A Mobile's average benchmark score of 8,746 places it at the 44th percentile of all GPUs, while the Rubin GPU's placeholder 50th percentile reflects its unmeasured status rather than any observed performance.

What can be stated from the database is that the RTX 3050 A Mobile's nearest rivals include the GeForce GTX 460 v2 with an average score of 8,743 (0% delta), the Quadro P2200 at 8,686 (0.7% higher), the AMD Radeon R9 M265X at 8,851 (1.2% lower), and the AMD Radeon Pro WX 5100 at 8,863 (1.3% lower). These deltas are all within 1.3 percentage points, indicating the RTX 3050 A Mobile sits in a tightly clustered performance band among its peers. The Rubin GPU has no comparable data points.

Where Each One Wins

For the RTX 3050 A Mobile, the wins are defined by measurable outcomes. It delivers 4.813 TFLOPS of FP32 compute and the same 4.813 TFLOPS for FP16 at a 1:1 ratio. Its pixel rate reaches 42.98 GPixel/s, and its texture rate hits 75.21 GTexel/s. These figures support real-world workloads in DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, as recorded in the database. The GPU's 4 GB GDDR6 memory on a 128-bit bus provides 192.0 GB/s of bandwidth, which the benchmark scores reflect in the 52,998 OpenCL result.

The Rubin GPU wins in raw specifications that have no corresponding benchmark validation. Its FP32 output is 130.0 TFLOPS, its FP16 is 260.0 TFLOPS at a 2:1 ratio, and its texture rate reaches 2,031.2 GTexel/s. The pixel rate of 54.41 GPixel/s is higher than the RTX 3050 A Mobile's 42.98 GPixel/s. Memory capacity jumps to 288 GB of HBM4 on a 16,384-bit bus, yielding 22.1 TB/s of bandwidth. These are architectural capabilities, not tested results, so the database treats them as unverified specifications.

The use-case split follows the data: the RTX 3050 A Mobile is a measured performer in the 44th percentile with direct benchmarks across six Passmark tests and one Geekbench test. The Rubin GPU is a specification-only entity with no recorded execution data, placing it outside any empirical comparison.

Architecture Differences

The RTX 3050 A Mobile uses the GA106 chip built on Ampere architecture, fabricated by Samsung on an 8 nm process. It contains 12,000 million transistors on a 276 mm² die, giving a transistor density of 43.5 million per mm². The Rubin GPU uses the GR100 chip on Rubin architecture, fabricated by TSMC on a 3 nm process. Its transistor count is 336,000 million on a 1,456 mm² die, with a density of 230.8 million per mm². The density difference is substantial: the Rubin GPU packs roughly 5.3 times more transistors per square millimeter.

Shading units differ massively: the RTX 3050 A Mobile has 1,792, while the Rubin GPU has 28,672. Texture mapping units are 56 versus 896. Raster output units are 32 versus 24, which is a rare case of the smaller GPU having more ROPs. Ray tracing cores exist on the RTX 3050 A Mobile at 14, but the Rubin GPU lists null for RT cores in the database. Tensor cores are 56 on the RTX 3050 A Mobile and 896 on the Rubin GPU.

Clock behavior diverges sharply. The RTX 3050 A Mobile has a base clock of 1065 MHz and a boost of 1343 MHz. The Rubin GPU has a lower base of 700 MHz but a much higher boost of 2267 MHz. Memory clocks are 1500 MHz (12 Gbps effective) for the RTX 3050 A Mobile and 2695 MHz (10.8 Gbps effective) for the Rubin GPU. The FP16 ratio changes from 1:1 on the older chip to 2:1 on the newer one, indicating a different compute path.

Power and interface differences are pronounced. The RTX 3050 A Mobile is rated at 45 W TDP, uses an IGP slot width, has no power connectors, and runs on PCIe 4.0 x8. The Rubin GPU is rated at 2300 W TDP, uses an SXM Module slot width, requires a suggested PSU of 2700 W, and runs on PCIe 6.0 x16. The RTX 3050 A Mobile's display outputs are portable-device dependent, while the Rubin GPU has no outputs at all. API support also differs: the RTX 3050 A Mobile supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The Rubin GPU lists N/A for DirectX, OpenGL, and Vulkan.

Production status separates them further. The RTX 3050 A Mobile is end-of-life with a release date of 2023-12-31. The Rubin GPU is active with a release date of 2025-12-31. The RTX 3050 A Mobile's predecessor is GeForce 20 Mobile; the Rubin GPU's predecessor is Server Blackwell.

The Verdict

The data supports only one empirical verdict. The RTX 3050 A Mobile has recorded benchmark results, a defined percentile rank, and a set of nearest rivals with comparable scores. The Rubin GPU has no benchmark results, no rivals, and an average score of zero. Any decision between these two must account for the fact that one is a tested, shipping product and the other is a specification sheet with no measured output.

For users who need a mobile GPU with DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 support, the RTX 3050 A Mobile is the only choice with verified performance. Its 44th percentile ranking and average score of 8,746 place it in a known performance class. The Rubin GPU cannot fill that role because it has no display outputs and no API support in the database.

For users who need massive compute throughput in a server context, the Rubin GPU's specifications suggest a different class of capability: 130.0 TFLOPS FP32, 260.0 TFLOPS FP16, and 22.1 TB/s bandwidth. But these numbers carry no benchmark confirmation. The database records zero test scores for this part.

The RTX 3050 A Mobile wins on evidence. The Rubin GPU wins on paper. Strictly from the data, the RTX 3050 A Mobile is the only one that can be evaluated for real workloads, while the Rubin GPU remains an unproven specification.
