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

The Verdict

The data is unambiguous: the NVIDIA GeForce RTX 4090 Mobile is in a completely different performance class than the RTX 3050 Mobile. In the recorded head-to-head benchmarks, the RTX 4090 Mobile wins both tests by massive margins, with a 261.4% advantage in Geekbench OpenCL and a 248.2% advantage in Geekbench Vulkan. The average benchmark score tells the same story: the RTX 4090 Mobile averages 43,667 across all recorded tests, while the RTX 3050 Mobile averages 33,170. That is a 31.6% overall gap, and it understates the real difference because the RTX 3050 Mobile's average is pulled by only three recorded tests, while the RTX 4090 Mobile has nine.

The RTX 4090 Mobile is the pick for anyone who prioritizes raw compute performance in both OpenCL and Vulkan workloads, especially tasks like GPGPU compute, rendering, or high-end gaming where the 261.4% and 248.2% deltas will be felt immediately. The RTX 3050 Mobile, by contrast, sits at the 78th percentile of all GPUs in the database, which is respectable, but it trails the RTX 4090 Mobile's 84th percentile. The RTX 3050 Mobile is the choice only for systems where power and thermal constraints are severe, given its 45 W TDP versus the RTX 4090 Mobile's 120 W TDP, and where the workload is light enough that the 4 GB memory capacity is sufficient. For any demanding task, the RTX 4090 Mobile wins outright.

Architecture Differences

The two GPUs come from different architectural generations and are built on different process nodes. The RTX 4090 Mobile uses the AD103 chip with the Ada Lovelace architecture, fabricated by TSMC on a 5 nm process. The RTX 3050 Mobile uses the GA107 chip with the Ampere architecture, fabricated by Samsung on an 8 nm process. The process node difference is significant: 5 nm versus 8 nm, and the transistor counts reflect the scale gap. The RTX 4090 Mobile packs 45,900 million transistors on a 379 mm² die, yielding a transistor density of 121.1 million per mm². The RTX 3050 Mobile has just 8,700 million transistors on a 200 mm² die, for a density of 43.5 million per mm². That is a 527.6% difference in total transistor count and a 178.4% difference in density.

The core configurations are equally lopsided. The RTX 4090 Mobile has 9,728 shading units, 304 texture mapping units, 112 render output units, 76 ray tracing cores, and 304 tensor cores. The RTX 3050 Mobile has 2,048 shading units, 64 TMUs, 32 ROPs, 16 ray tracing cores, and 64 tensor cores. The RTX 4090 Mobile leads by 475% in shading units, 475% in TMUs, 350% in ROPs, 475% in ray tracing cores, and 475% in tensor cores. The compute rates follow: the RTX 4090 Mobile delivers 32.98 TFLOPS FP32 and FP16 (1:1), while the RTX 3050 Mobile delivers 5.501 TFLOPS in both. That is a 499.5% advantage in raw floating-point throughput. Pixel rate is 189.8 GPixel/s versus 42.98 GPixel/s, a 341.6% lead, and texture rate is 515.3 GTexel/s versus 85.95 GTexel/s, a 499.5% lead.

Both chips support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so feature-level API support is identical. The RTX 4090 Mobile uses a PCIe 4.0 x16 bus interface, while the RTX 3050 Mobile uses PCIe 4.0 x8. Both are listed as IGP slot width with no power connectors, and both have display outputs described as portable device dependent. The RTX 4090 Mobile was released on 2023-01-02, and the RTX 3050 Mobile on 2021-05-10. The RTX 4090 Mobile is still in active production, while the RTX 3050 Mobile is end-of-life. The RTX 4090 Mobile's predecessor is the GeForce 30 Mobile and its successor is the GeForce 50 Mobile; the RTX 3050 Mobile's predecessor is the GeForce 20 Mobile with no successor listed.

Head-to-Head Benchmarks

The recorded head-to-head data contains two tests, and the RTX 4090 Mobile wins both. In Geekbench OpenCL, the RTX 4090 Mobile scores 180,831 against the RTX 3050 Mobile's 50,038. The delta is 261.4%, meaning the RTX 4090 Mobile is roughly 3.6 times faster in this OpenCL workload. In Geekbench Vulkan, the RTX 4090 Mobile scores 170,774 against 49,051, a delta of 248.2%, or roughly 3.5 times faster. The Vulkan gap is slightly smaller than the OpenCL gap, but both are enormous. There is no recorded test where the RTX 3050 Mobile wins; the wins tally is 2 for the RTX 4090 Mobile and 0 for the RTX 3050 Mobile.

Looking at the broader benchmark suite, the RTX 4090 Mobile has additional recorded results that reinforce its position. Its Passmark G3D score is 27,212, its Passmark GPU compute score is 12,347, and its Geekbench Vulkan score of 170,774 is the second highest among its recorded tests, behind only the OpenCL score. The RTX 3050 Mobile's only other recorded test is 3DMark Steel Nomad DX12, where it scores 421, but there is no comparable 3DMark result for the RTX 4090 Mobile, so a direct comparison on that test is not possible. The average benchmark scores provide context: the RTX 4090 Mobile's 43,667 average places it near the NVIDIA RTX A6000 (44,075, a 0.9% gap in favor of the A6000) and the NVIDIA Quadro M6000 (43,301, a 0.8% gap in favor of the M6000). The RTX 3050 Mobile's 33,170 average sits near the NVIDIA T550 Mobile (33,161, a 0% gap) and the AMD Radeon Pro 570 (33,207, a 0.1% gap in favor of the AMD part). In other words, the RTX 4090 Mobile is competing with workstation-class GPUs, while the RTX 3050 Mobile is competing with entry-level mobile and workstation parts.

Where Each One Wins

The RTX 4090 Mobile wins every recorded head-to-head benchmark, so the use-case split is defined by the magnitude of the performance gap and by the specification differences rather than by any test the RTX 3050 Mobile wins.

The RTX 4090 Mobile is the clear choice for compute-heavy workloads. Its 32.98 TFLOPS FP32 and FP16 (1:1) output is 499.5% higher than the RTX 3050 Mobile's 5.501 TFLOPS, which makes it dramatically better suited for GPGPU compute, machine learning inference, rendering, and any task that scales with raw shading and tensor core throughput. The 16 GB memory capacity, 576.0 GB/s bandwidth, and 256 bit bus provide 4 times the memory and 3 times the bandwidth, so large datasets and high-resolution textures will fit comfortably. The 76 ray tracing cores versus 16 means ray-traced workloads will also favor the RTX 4090 Mobile heavily. The 84th percentile ranking among all GPUs, with nearest rivals being the NVIDIA RTX A6000 and Quadro M6000, places this part in workstation-class territory. Its 2-0 win record in the head-to-head tests, with deltas of 261.4% and 248.2%, means it is not merely faster, it is in a different tier.

The RTX 3050 Mobile wins in scenarios where power draw is the limiting factor. At 45 W TDP versus 120 W, it consumes 62.5% less power, making it suitable for thinner, cooler, and longer-battery-life laptops where the RTX 4090 Mobile's 120 W requirement would be impractical. The 78th percentile ranking is still above average, and its nearest rivals (NVIDIA T550 Mobile, AMD Radeon Pro 570, NVIDIA P104-100, NVIDIA T600 Mobile) are all within a 1% delta, meaning it is a competitive entry-level mobile part. For light gaming, basic 3D applications, or OpenCL and Vulkan workloads that do not need more than 4 GB of memory, the RTX 3050 Mobile is adequate. However, its 3DMark Steel Nomad DX12 score of 421 is the only test where it has a result the RTX 4090 Mobile cannot be compared against, so there is no recorded evidence of any workload where it outperforms the RTX 4090 Mobile. The RTX 4090 Mobile is the winner for anyone who needs maximum performance; the RTX 3050 Mobile is the winner only for systems that cannot accommodate the power and thermal envelope of the larger chip.
