NVIDIA GeForce RTX 4050 Mobile vs NVIDIA GeForce RTX 5070 Mobile Comparison

NVIDIA GeForce RTX 4050 Mobile and NVIDIA GeForce RTX 5070 Mobile are both mobile GPUs from NVIDIA, based on different generations of the company's architecture. The RTX 5070 Mobile, released in 2025, replaces the RTX 4050 Mobile from 2023. The recorded data shows a clear generational shift, with the newer part winning every single benchmark in the database, though the margins vary significantly across different workloads, particularly in legacy DirectX tests versus modern compute tasks.

Head-to-Head Benchmarks

The RTX 5070 Mobile dominates the RTX 4050 Mobile across all nine recorded benchmarks. The largest single performance gap appears in the Geekbench OpenCL test, where the RTX 5070 Mobile scores 122238 against the RTX 4050 Mobile's 74748, a delta of 38.9 percent. This is closely followed by the Passmark DirectX 10 test, where the RTX 5070 Mobile's 129 score represents a 38.8 percent advantage over the 79 scored by the RTX 4050 Mobile. The Geekbench Vulkan benchmark shows a similar pattern, with the newer GPU reaching 116960 points versus 75235 points, a 35.7 percent lead.

The modern DirectX 12 and DirectX 11 tests also show substantial gaps. In DirectX 12, the RTX 5070 Mobile scores 93 against the RTX 4050 Mobile's 61, a 34.4 percent difference. DirectX 11 results are closer in percentage terms but still decisive: 192 versus 130, a 32.3 percent advantage for the RTX 5070 Mobile. The smallest margin in the entire comparison is in the DirectX 9 test, where the RTX 5070 Mobile's 214 score beats the RTX 4050 Mobile's 184 by only 14 percent. This suggests that while the newer architecture is faster across the board, its advantage narrows considerably in older, less demanding rendering paths.

Compute and general-purpose results follow the same trend. The Passmark GPU Compute test shows the RTX 5070 Mobile scoring 8279 versus 5947, a 28.2 percent lead. The Passmark G3D test, which aggregates overall 3D performance, shows a 29.1 percent gap, with scores of 20355 and 14423 respectively. The 2D test, Passmark G2D, sees the RTX 5070 Mobile at 896 and the RTX 4050 Mobile at 633, a 29.4 percent difference. In every case, the RTX 5070 Mobile is the winner, and the data records zero wins for the RTX 4050 Mobile.

Where Each One Wins

The RTX 5070 Mobile wins every benchmark category, so the analysis of "where each one wins" must focus on the magnitude of those wins rather than any reversal of positions. The RTX 5070 Mobile shows its strongest relative advantage in compute-heavy and modern API workloads. The Geekbench OpenCL, Geekbench Vulkan, and Passmark DirectX 10 tests all show gaps above 35 percent, indicating that the newer architecture's raw compute throughput and shader execution scale particularly well in these scenarios.

The RTX 4050 Mobile, while losing outright, demonstrates its most competitive showing in the DirectX 9 test, where the gap narrows to 14 percent. This indicates that for legacy applications built around older DirectX pipelines, the older GPU is relatively less disadvantaged. Similarly, the Passmark GPU Compute and G3D tests show gaps around 28 to 29 percent, slightly better for the RTX 4050 Mobile than the OpenCL and Vulkan results. For users running older games or applications that rely on DirectX 9, the RTX 4050 Mobile remains within striking distance, though still behind. For modern workloads that leverage DirectX 12, Vulkan, or OpenCL compute, the RTX 5070 Mobile pulls ahead by a third or more, making those scenarios heavily skewed toward the newer part.

Architecture Differences

The two GPUs come from different architectures and process generations. The RTX 4050 Mobile uses the AD107 chip, part of the Ada Lovelace architecture, while the RTX 5070 Mobile uses the GB206 chip with the Blackwell 2.0 architecture. Both are manufactured by TSMC on a 5 nm process node, but the newer chip is larger and denser. The GB206 chip contains 21,900 million transistors on a 181 mm² die, yielding a transistor density of 121.0 million per mm². The AD107 is smaller at 159 mm² with 18,900 million transistors, for a density of 118.9 million per mm².

The memory subsystem sees major changes. The RTX 4050 Mobile uses 6 GB of GDDR6 memory on a 96-bit bus, providing 192.0 GB/s of bandwidth. The RTX 5070 Mobile steps up to 8 GB of GDDR7 memory on a 128-bit bus, doubling bandwidth to 384.0 GB/s. Effective memory speed also increases from 16 Gbps to 24 Gbps. The newer GPU also switches to a PCIe 5.0 x16 interface, while the older part uses PCIe 4.0 x8.

The compute configuration differs substantially. The RTX 5070 Mobile has 4608 shading units, 144 texture mapping units, and 48 ROPs, compared to the RTX 4050 Mobile's 2560 shading units, 80 TMUs, and 48 ROPs. The ROP count is identical, but the newer GPU doubles the shader count and nearly doubles texture units. Ray tracing and tensor hardware also scales up: the RTX 5070 Mobile has 36 RT cores and 144 tensor cores, versus 20 RT cores and 80 tensor cores on the RTX 4050 Mobile. This results in FP32 performance of 13.13 TFLOPS for the RTX 5070 Mobile versus 8.986 TFLOPS for the RTX 4050 Mobile, with FP16 running at the same 1:1 ratio in both cases.

Clock speeds tell a different story. The RTX 4050 Mobile runs at a base clock of 1455 MHz and a boost clock of 1755 MHz, significantly higher than the RTX 5070 Mobile's 907 MHz base and 1425 MHz boost. Despite the lower clocks, the RTX 5070 Mobile delivers higher texture rate (205.2 GTexel/s versus 140.4 GTexel/s) and lower pixel rate (68.40 GPixel/s versus 84.24 GPixel/s), because the pixel throughput depends on the fixed 48 ROPs at differing clocks. Both GPUs carry a 50 W TDP, use an integrated form factor (IGP), and rely on no external power connectors. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

The Verdict

The benchmark data is unambiguous. The RTX 5070 Mobile outperforms the RTX 4050 Mobile in every recorded test, with average benchmark scores of 29928 versus 19049. The RTX 5070 Mobile sits at the 75th percentile among all GPUs, while the RTX 4050 Mobile rests at the 63rd percentile. The nearest rivals for the RTX 5070 Mobile include the NVIDIA GeForce RTX 3070 Ti (average score 29945, a 0.1 percent difference) and the NVIDIA GeForce RTX 2080 Ti (29783, 0.5 percent behind). The RTX 4050 Mobile's closest peers are the AMD Radeon RX 6600 (19036, 0.1 percent ahead) and the NVIDIA Quadro K6000 (19030, 0.1 percent ahead), placing it in a much lower performance tier.

For users choosing between these two, the data shows that the RTX 5070 Mobile is the superior choice for almost any workload. Its advantages are largest in OpenCL compute, Vulkan, and DirectX 10, where it leads by roughly 36 to 39 percent. In DirectX 11 and DirectX 12, the lead narrows to 32 to 34 percent, still a massive margin. Even in DirectX 9, where the RTX 4050 Mobile is relatively strongest, the newer GPU still leads by 14 percent. The RTX 5070 Mobile also brings twice the memory bandwidth and newer GDDR7 memory, which future workloads may exploit further. The RTX 4050 Mobile, with its higher clock speeds, cannot compensate for fewer shaders, fewer RT cores, and less memory bandwidth. The only scenario where the RTX 4050 Mobile appears less disadvantaged is legacy DirectX 9 content, but it still loses there. The verdict from the recorded data is straightforward: the RTX 5070 Mobile is the faster GPU in all measured categories.
