NVIDIA GeForce RTX 3050 A Mobile vs NVIDIA GeForce RTX 4070 Comparison

Where Each One Wins

The recorded benchmark data draws a clear and uncompromising separation between these two NVIDIA mobile and desktop parts. The NVIDIA GeForce RTX 4070 wins every single head-to-head comparison in the database, taking all eight recorded tests. The RTX 3050 A Mobile does not register a single victory across any workload category, from legacy DirectX 9 titles to modern DirectX 12 and compute-oriented tasks.

The use-case split is therefore defined not by which GPU wins a given scenario, but by the magnitude of the RTX 4070's advantage and the distinct hardware roles each part occupies. The RTX 3050 A Mobile is an integrated-class part with a 45 W power envelope, designed for thin-and-light portable systems where physical space and thermal limits dominate. Its slot width is listed as IGP (integrated graphics processor), it draws power through no external connectors, and its display outputs are portable-device dependent. This is a GPU built to enable basic gaming and general graphics acceleration inside a laptop chassis, not to drive high-refresh 1440p monitors or demanding creative workloads.

The RTX 4070, by contrast, is a dual-slot desktop board measuring 240 mm in length, 110 mm in height, and 40 mm in width, with a 200 W power draw and a single 16-pin power connector. Its suggested power supply is 550 W. The database positions it at the 81st percentile of all GPUs, a strong placement that indicates it sits comfortably within the upper tier of recorded graphics hardware. The RTX 3050 A Mobile, at the 44th percentile, sits just below the middle of the distribution. The data shows the RTX 4070 is the clear choice for desktop gaming, 3D rendering, and GPU compute; the RTX 3050 A Mobile is best understood as a capable integrated solution for portable machines where the RTX 4070's physical footprint and power requirements are simply not viable.

Architecture Differences

The architectural gap between these two GPUs is generational and manufacturing-based. The RTX 3050 A Mobile uses the GA106 chip built on Samsung's 8 nm process node, part of the Ampere architecture from the GeForce 30-series. The RTX 4070 uses the AD104 chip fabricated by TSMC on a 5 nm node, belonging to the Ada Lovelace architecture and the GeForce 40-series. The transistor counts reflect the process difference: the GA106 packs 12,000 million transistors into a 276 mm² die, yielding a density of 43.5 million transistors per square millimeter. The AD104 contains 35,800 million transistors on a slightly larger 294 mm² die, achieving 121.8 million transistors per square millimeter. That is a 2.8x density improvement per square millimeter, and it explains how the RTX 4070 fits nearly three times the transistor count into similar physical space.

Core counts scale accordingly. The RTX 3050 A Mobile has 1,792 shading units, 56 texture mapping units, 32 ROPs, 14 ray tracing cores, and 56 tensor cores. The RTX 4070 more than triples the shading units to 5,888, triples the TMUs to 184, doubles the ROPs to 64, and raises ray tracing cores to 46 with 184 tensor cores. Clock speeds also differ substantially. The RTX 3050 A Mobile runs at a 1065 MHz base and 1343 MHz boost, while the RTX 4070 operates at 1920 MHz base and 2475 MHz boost. The higher clock and core count combine to produce a theoretical FP32 throughput of 29.15 TFLOPS for the RTX 4070 versus 4.813 TFLOPS for the RTX 3050 A Mobile, a roughly 6x gap in raw compute.

Memory configuration is another major separator. The RTX 3050 A Mobile has 4 GB of GDDR6 on a 128-bit bus with 192.0 GB/s of bandwidth and a 1500 MHz memory clock (12 Gbps effective). The RTX 4070 has 12 GB of GDDR6X on a 192-bit bus with 504.2 GB/s of bandwidth and a 1313 MHz memory clock (21 Gbps effective). The RTX 4070 provides 2.6x the bandwidth and 3x the capacity, which matters for texture-heavy workloads and larger datasets. The RTX 3050 A Mobile also uses a PCIe 4.0 x8 interface while the RTX 4070 uses PCIe 4.0 x16, doubling the available bus lanes. Both parts support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API feature coverage is identical.

Head-to-Head Benchmarks

The largest single victory for the RTX 4070 comes in compute performance. In the Passmark GPU Compute test, the RTX 4070 scores 14,720 against 4,419 for the RTX 3050 A Mobile, a delta of -70% from the perspective of the smaller GPU. This is the widest gap of any recorded test and aligns with the FP32 throughput difference, where the RTX 4070's 29.15 TFLOPS versus 4.813 TFLOPS gives it a commanding lead in general-purpose compute workloads.

In the Geekbench OpenCL test, the RTX 4070 scores 154,858 against 52,998 for the RTX 3050 A Mobile, a delta of -65.8%. This is the second-largest margin and reinforces the compute advantage. The RTX 4070 also records a Geekbench Vulkan score of 174,152, a test that does not appear in the RTX 3050 A Mobile's benchmark list, so no direct comparison is available there.

Graphics API scaling shows a consistent but somewhat narrower advantage. In Passmark DirectX 11, the RTX 4070 scores 244 versus 94, a -61.5% delta. In DirectX 10, the scores are 139 versus 61, a -56.1% delta. DirectX 9 shows 320 versus 152, a -52.5% delta. The smallest gap is in DirectX 12, where the RTX 4070 scores 103 against 55, a -46.6% delta. The fact that the DirectX 12 gap is the narrowest suggests the newer API compresses some of the architectural differences, though the RTX 4070 still wins by a substantial margin.

The overall 3D graphics score follows the same pattern. The Passmark G3D test gives the RTX 4070 a 26,927 score against 11,664 for the RTX 3050 A Mobile, a -56.7% delta. The 2D graphics test shows 1,164 versus 526, a -54.8% delta. Across all eight recorded head-to-head tests, the RTX 4070 wins by deltas ranging from -46.6% to -70%, with a median gap around -56%. The RTX 3050 A Mobile's average benchmark score is 8,746, while the RTX 4070 averages 37,648, a 4.3x difference in aggregate performance.

The Verdict

The database shows no ambiguity: the NVIDIA GeForce RTX 4070 outperforms the RTX 3050 A Mobile in every recorded benchmark, with deltas between -46.6% and -70%. The RTX 4070 delivers more than triple the shading units, more than triple the FP32 throughput, 2.6x the memory bandwidth, and 3x the VRAM capacity. Its 81st percentile placement against the RTX 3050 A Mobile's 44th percentile places it in a completely different performance class.

The RTX 3050 A Mobile is not without purpose. Its 45 W power envelope, lack of external power connectors, and IGP slot width make it suitable for portable systems where the 200 W, dual-slot, 240 mm RTX 4070 physically cannot fit. For users constrained to a thin laptop chassis, the RTX 3050 A Mobile provides functional graphics acceleration with a DirectX 12 Ultimate feature set, and its nearest rivals in the database are mid-range parts like the Quadro P2200 and Radeon R9 M265X, with average scores within 1.3% of its own.

For anyone building or upgrading a desktop system, the data favors the RTX 4070 overwhelmingly. Its nearest rivals include the RTX 4080 Mobile at -1.3% and the Tesla P4 at +0.1%, placing it in the upper tier of recorded GPUs. The RTX 4070's launch MSRP is 599 USD. The RTX 3050 A Mobile has no recorded launch MSRP. The choice between these two is not a performance trade-off but a form-factor decision: the RTX 3050 A Mobile exists for integrated mobile contexts, and the RTX 4070 exists for desktop performance. The recorded scores indicate that any workload that can run on the RTX 3050 A Mobile will run substantially faster on the RTX 4070, with the widest gaps appearing in compute-heavy tasks.
