NVIDIA GeForce RTX 3050 A Mobile vs NVIDIA GeForce RTX 4090 Mobile Comparison

Head-to-Head Benchmarks

The benchmark data presents an unambiguous picture: the NVIDIA GeForce RTX 4090 Mobile wins all eight recorded head-to-head comparisons. The largest margin appears in Geekbench OpenCL, where the RTX 4090 Mobile scores 180,831 against the RTX 3050 A Mobile's 52,998, a delta of -70.7% for the latter. That is the single biggest performance gap in the entire dataset.

DirectX 10 and DirectX 11 results follow a similar pattern. In Passmark DirectX 10, the RTX 4090 Mobile posts 173 versus 61, a -64.7% delta. DirectX 11 shows 262 versus 94, a -64.1% gap. These two legacy API tests indicate that even older workloads, which typically scale less with raw compute, still heavily favor the larger chip.

Compute-heavy workloads reinforce the hierarchy. Passmark GPU Compute scores 12,347 for the RTX 4090 Mobile versus 4,419 for the RTX 3050 A Mobile, a -64.2% delta. The DirectX 12 test is comparatively closer, with 107 against 55, a -48.6% delta, but the RTX 4090 Mobile still nearly doubles the score. DirectX 9 shows 310 versus 152, a -51% delta.

The 2D graphics test, Passmark G2D, delivers the smallest relative gap. The RTX 4090 Mobile scores 984, while the RTX 3050 A Mobile manages 526, a -46.5% delta. This test measures less GPU-bound operations, so the smaller margin is consistent with expectations. The overall Passmark G3D score, a broad gaming and graphics metric, lands at 27,212 for the RTX 4090 Mobile and 11,664 for the RTX 3050 A Mobile, a -57.1% delta.

The average benchmark score in the database tells the same story from a different angle. The RTX 3050 A Mobile averages 8,746 points across all recorded tests, placing it in the 44th percentile of all GPUs. The RTX 4090 Mobile averages 43,667 points, sitting in the 84th percentile. That is a roughly fivefold difference in average score, and the percentile spread from below-median to well-above-median illustrates how far apart these two parts are in overall capability.

Architecture Differences

The two GPUs come from different generations and fundamentally different designs. The RTX 3050 A Mobile uses the GA106 chip on Samsung's 8 nm process, belonging to the Ampere architecture and the GeForce 30 Mobile family. The RTX 4090 Mobile uses the AD103 chip on TSMC's 5 nm node, built on Ada Lovelace and part of the GeForce 40 Mobile line. The process shrink from 8 nm to 5 nm is a major factor in the performance gap, as is the transistor budget.

Transistor counts differ massively. The GA106 packs 12,000 million transistors on a 276 mm² die, yielding a density of 43.5 million transistors per square millimeter. The AD103 contains 45,900 million transistors on a 379 mm² die, for a density of 121.1 million per square millimeter. The RTX 4090 Mobile not only has nearly four times the transistors, it also packs them far more densely, which explains how it delivers dramatically higher throughput despite a less extreme die size increase.

Core counts follow the same trajectory. The RTX 3050 A Mobile has 1,792 shading units, 56 texture mapping units, 32 ROPs, 14 RT cores, and 56 tensor cores. The RTX 4090 Mobile has 9,728 shading units, 304 TMUs, 112 ROPs, 76 RT cores, and 304 tensor cores. Every category scales by a factor of roughly 5 to 6, matching the FP32 throughput difference: 4.813 TFLOPS versus 32.98 TFLOPS, both at 1:1 FP16 ratios.

Memory configurations are equally divergent. The RTX 3050 A Mobile uses 4 GB of GDDR6 on a 128-bit bus, with memory clocked at 1500 MHz (12 Gbps effective) for 192.0 GB/s of bandwidth. The RTX 4090 Mobile uses 16 GB of GDDR6 on a 256-bit bus, with memory at 2250 MHz (18 Gbps effective) for 576.0 GB/s. That is three times the bandwidth and four times the capacity.

Clock speeds also favor the newer part. The RTX 3050 A Mobile has a base clock of 1065 MHz and a boost of 1343 MHz. The RTX 4090 Mobile runs at 1335 MHz base and 1695 MHz boost. Higher clocks on a smaller process node with vastly more cores compound the performance difference.

The bus interface differs as well. The RTX 3050 A Mobile uses PCIe 4.0 x8, while the RTX 4090 Mobile uses PCIe 4.0 x16. Both are IGP slot types with no power connectors and portable-device-dependent display outputs. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API feature parity is maintained.

Power draw reflects the performance gulf. The RTX 3050 A Mobile carries a 45 W TDP, while the RTX 4090 Mobile is rated at 120 W. The production status also differs: the RTX 3050 A Mobile is end-of-life, while the RTX 4090 Mobile is active and lists a successor, the GeForce 50 Mobile.

The Verdict

The data indicates that the RTX 4090 Mobile is in a completely different performance class. Every recorded benchmark, from legacy DirectX 9 to modern OpenCL, shows the RTX 4090 Mobile winning by at least 46.5% and often by more than 60%. The RTX 3050 A Mobile has zero wins across the eight head-to-head tests.

The RTX 3050 A Mobile's average score of 8,746 places it near the NVIDIA GeForce GTX 460 v2 (8,743, a 0% delta) and the NVIDIA Quadro P2200 (8,686, a 0.7% delta in its favor). It also trails the AMD Radeon R9 M265X by 1.2% and the AMD Radeon Pro WX 5100 by 1.3%. These rivals are all older or lower-tier parts, confirming that the RTX 3050 A Mobile occupies a modest performance bracket.

The RTX 4090 Mobile's average of 43,667 places it near the NVIDIA Quadro M6000 (43,301, a 0.8% delta in its favor), the NVIDIA GeForce RTX 5050 Mobile (43,268, a 0.9% delta in its favor), and the NVIDIA RTX A6000 (44,075, a -0.9% delta against it). These are professional and high-end workstation GPUs, which contextualizes the RTX 4090 Mobile as a top-tier part.

Given the production status, the RTX 3050 A Mobile is end-of-life, while the RTX 4090 Mobile is active with a successor already listed. For any workload that leverages the GPU's compute, memory bandwidth, or ray tracing hardware, the RTX 4090 Mobile is the only rational choice based on the available measurements.

Where Each One Wins

The RTX 4090 Mobile wins every category in the recorded data. For gaming workloads, the Passmark G3D score of 27,212 versus 11,664 shows it delivers over twice the overall graphics performance. For compute tasks, the Passmark GPU Compute score of 12,347 versus 4,419 indicates a nearly threefold advantage. For bandwidth-sensitive applications, the 576.0 GB/s versus 192.0 GB/s memory throughput is decisive.

The RTX 3050 A Mobile has no benchmark wins, but its profile suggests specific constraints rather than advantages. The 45 W TDP means it draws less than half the power of the RTX 4090 Mobile, which could matter in thermally limited chassis. The 4 GB memory capacity is sufficient for lighter workloads, and the 128-bit bus keeps the memory subsystem simpler. However, none of these characteristics translate into a performance win in the database.

For users constrained to a 45 W power envelope, the RTX 3050 A Mobile is the only option between these two. For anyone else, the RTX 4090 Mobile's dominance across all eight benchmarks, its active production status, and its higher percentile ranking make it the clear choice. The RTX 3050 A Mobile belongs to a previous generation and is end-of-life, while the RTX 4090 Mobile represents the current high-end mobile tier. The data does not support any scenario where the RTX 3050 A Mobile outperforms the RTX 4090 Mobile in a measurable way.
