NVIDIA GeForce RTX 3050 A Mobile vs NVIDIA GeForce RTX 5070 Mobile Comparison

Head-to-Head Benchmarks

The recorded data shows a complete sweep for the NVIDIA GeForce RTX 5070 Mobile, winning all eight head-to-head comparisons against the RTX 3050 A Mobile. The largest margin appears in Geekbench OpenCL, where the RTX 5070 Mobile scores 122,238 versus 52,998, a 56.6% advantage. This is the widest gap in the entire comparison, indicating that raw compute throughput scales dramatically between the two generations.

DirectX 10 and DirectX 11 workloads show similar dominance. The RTX 5070 Mobile posts 129 against 61 in DirectX 10, a 52.7% lead, and 192 versus 94 in DirectX 11, a 51% lead. These legacy API tests suggest that even older rendering paths benefit substantially from the newer architecture's higher shading unit count and memory bandwidth, not just from modern feature optimizations.

The DirectX 12 test narrows the gap somewhat, with the RTX 5070 Mobile scoring 93 against 55, a 40.9% difference. DirectX 9 shows the smallest relative margin at 29%, with scores of 214 and 152. This pattern implies that the RTX 3050 A Mobile holds up relatively better in older, less parallel workloads, while the RTX 5070 Mobile's advantage grows as the workload becomes more compute-intensive.

In 3D rendering, measured by PassMark G3D, the RTX 5070 Mobile delivers 20,355 versus 11,664, a 42.7% lead. The 2D test shows a 41.3% gap, 896 versus 526. Compute performance, tracked by PassMark GPU Compute, shows 8,279 against 4,419, a 46.6% difference. Across all categories, the RTX 5070 Mobile's average benchmark score of 29,928 dwarfs the RTX 3050 A Mobile's 8,746, a 3.4x gap in overall aggregate performance.

Architecture Differences

The two GPUs come from completely different design generations. The RTX 3050 A Mobile uses the GA106 chip built on Ampere architecture, manufactured on an 8 nm process at Samsung. The RTX 5070 Mobile uses the GB206 chip on Blackwell 2.0 architecture, built on a 5 nm process at TSMC. This process shrink allows the RTX 5070 Mobile to pack 21,900 million transistors into a 181 mm² die, achieving a transistor density of 121.0M per mm². The RTX 3050 A Mobile contains 12,000 million transistors on a larger 276 mm² die, with a density of 43.5M per mm². The newer chip fits nearly double the transistors into a smaller physical area.

Core counts differ substantially. The RTX 5070 Mobile has 4,608 shading units, 144 texture mapping units, and 48 ROPs. The RTX 3050 A Mobile has 1,792 shading units, 56 TMUs, and 32 ROPs. Ray tracing hardware scales from 14 RT cores to 36, and tensor cores grow from 56 to 144. These increases align with the 56.6% OpenCL gap, as the newer GPU has roughly 2.6x the shading units and 2.6x the tensor cores.

Clock behavior is counterintuitive. The RTX 5070 Mobile has a lower base clock of 907 MHz versus 1065 MHz, but a higher boost clock of 1425 MHz versus 1343 MHz. The effective memory speed jumps from 12 Gbps to 24 Gbps, doubling the memory clock while keeping the same 128-bit bus width. This doubles bandwidth from 192.0 GB/s to 384.0 GB/s, a critical factor for the 42.7% G3D advantage.

Memory configuration changes generationally. The RTX 3050 A Mobile offers 4 GB of GDDR6, while the RTX 5070 Mobile doubles capacity to 8 GB of GDDR7. Both use a 128-bit bus, but the newer memory standard and doubled clock rate deliver twice the bandwidth. The RTX 5070 Mobile also upgrades the bus interface from PCIe 4.0 x8 to PCIe 5.0 x16, though both are integrated into portable devices with no power connectors and IGP slot width. Power draw rises modestly from 45 W to 50 W, a 5 W increase that seems small relative to the performance jump.

API support is identical: both feature DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Production status differs, with the RTX 3050 A Mobile marked end-of-life and the RTX 5070 Mobile active. Release dates place them roughly 16 months apart, with the RTX 3050 A Mobile launching in early January 2024 and the RTX 5070 Mobile in mid-April 2025.

Where Each One Wins

The RTX 5070 Mobile wins every measured workload, but the margins tell a more nuanced story. Its strongest relative performance comes in compute-heavy tasks: OpenCL at 56.6% ahead, DirectX 10 at 52.7%, and DirectX 11 at 51%. These tests benefit from the 2.6x increase in shading units and the doubled memory bandwidth, which feed parallel workloads efficiently.

The RTX 3050 A Mobile's closest relative performance appears in DirectX 9 at 29% behind, and DirectX 12 at 40.9% behind. This suggests that legacy APIs, which rely more on fill rate and less on massive parallelism, reduce the newer GPU's advantage. The RTX 3050 A Mobile's 42.98 GPixel/s pixel rate and 75.21 GTexel/s texture rate are respectable for its class, but the RTX 5070 Mobile's 68.40 GPixel/s and 205.2 GTexel/s still outclass them.

For 2D and 3D workloads, the RTX 5070 Mobile holds a 41.3% and 42.7% lead respectively. Compute tasks show a 46.6% gap. Across the board, the RTX 5070 Mobile's percentile ranking of 75 versus 44 places it in a different performance tier entirely. Its nearest rivals include the RTX 3070 Ti (0.1% behind), RTX 2080 Ti (0.5% ahead), and RX 6800 (0.6% behind), indicating it competes with previous-generation high-end desktop GPUs. The RTX 3050 A Mobile, by contrast, sits alongside the GTX 460 v2, Quadro P2200, and R9 M265X, a much older performance bracket.

The Verdict

The benchmark data leaves no ambiguity: the RTX 5070 Mobile is categorically superior to the RTX 3050 A Mobile across every recorded test. The 8-0 win count, combined with an average score of 29,928 versus 8,746, establishes a performance gap that no workload reverses. The RTX 5070 Mobile's 75th percentile ranking, with nearest rivals like the RTX 3070 Ti and RTX 2080 Ti, shows it operates in a performance class roughly equivalent to previous-generation desktop flagships.

The RTX 3050 A Mobile's 44th percentile ranking places it near the GTX 460 v2 and Quadro P2200, which are legacy or workstation parts. Its only relative strengths are the narrower DirectX 9 and DirectX 12 margins, but these still result in losses. The 4 GB memory capacity, half the RTX 5070 Mobile's 8 GB, further limits its suitability for modern workloads, while the older GDDR6 and 12 Gbps clock constrain bandwidth to half the newer GPU's 384.0 GB/s.

Architecturally, the RTX 5070 Mobile benefits from a 5 nm process, higher transistor density, more shading units, more RT and tensor cores, and a newer memory standard. The RTX 3050 A Mobile is end-of-life, built on 8 nm, and fundamentally represents an earlier generation. The only specification where the RTX 3050 A Mobile does not trail is base clock, but its lower boost clock and far lower compute rates negate that advantage.

For any application requiring 3D rendering, compute acceleration, or memory-intensive workloads, the database points exclusively to the RTX 5070 Mobile. The RTX 3050 A Mobile remains viable only for scenarios where its lower 45 W TDP and older API behavior are sufficient, but even then, the RTX 5070 Mobile's 50 W TDP is barely higher. The data indicates a generational leap, not an incremental step, with the RTX 5070 Mobile delivering roughly 3.4x the aggregate benchmark score of its predecessor.
