NVIDIA GeForce RTX 4070 AD103 vs NVIDIA GeForce RTX 5070 Mobile Comparison

The Verdict

The database comparison between the NVIDIA GeForce RTX 4070 AD103 and the NVIDIA GeForce RTX 5070 Mobile presents a clear split based on performance class and form factor. The RTX 4070 AD103 is a desktop part with a 200 W power draw, a 5 nm TSMC process, and a 50th percentile ranking across all GPUs. In contrast, the RTX 5070 Mobile is an integrated laptop GPU at 50 W, built on the same 5 nm node but with a different architecture, and it sits at the 75th percentile. The data shows that the mobile part, despite its lower power envelope, achieves a higher percentile ranking, which suggests that its benchmark score distribution places it above the desktop model in the broader GPU landscape.

Benchmark results for the RTX 5070 Mobile show an average score of 29,928, while the RTX 4070 AD103 has no recorded benchmarks in the database, meaning its average score is zero. This absence of direct head-to-head data forces the analysis to rely on the mobile part’s nearest rivals for context. The RTX 5070 Mobile’s average score is nearly identical to the NVIDIA GeForce RTX 3070 Ti at 29,945, with a delta of -0.1%, and it is 0.5% ahead of the RTX 2080 Ti at 29,783. Against AMD, it trails the RX 6800 by 0.6% (30,095) and the RX 6700 by 1.7% (30,433). These deltas are small, indicating that the RTX 5070 Mobile performs in the same tier as those desktop cards from previous generations.

Given the data, the RTX 4070 AD103 is the choice for users who require a desktop GPU with higher raw throughput metrics, such as 29.15 TFLOPS FP32 and 504.2 GB/s memory bandwidth. The RTX 5070 Mobile is the choice for portable systems, as it delivers a competitive average score relative to older desktop flagships while consuming only 50 W. The database shows no wins for either part in head-to-head tests, so the verdict rests on specification differences and the mobile part’s benchmark percentile.

Architecture Differences

The two GPUs come from different NVIDIA generations. The RTX 4070 AD103 belongs to the GeForce 40-series and uses the Ada Lovelace architecture, while the RTX 5070 Mobile is part of the GeForce 50-series and uses Blackwell 2.0. Both are built on a 5 nm process at TSMC, but the die sizes differ significantly: the AD103 chip measures 379 mm² with 45,900 million transistors, whereas the GB206 chip in the mobile part is 181 mm² with 21,900 million transistors. The transistor density is nearly identical, at 121.1M per mm² for the desktop and 121.0M per mm² for the mobile.

The core configurations diverge. The RTX 4070 AD103 has 5,888 shading units, 184 texture mapping units, 64 ROPs, 46 RT cores, and 184 tensor cores. The RTX 5070 Mobile has 4,608 shading units, 144 TMUs, 48 ROPs, 36 RT cores, and 144 tensor cores. These counts indicate that the desktop part has roughly 28% more shading units and 28% more RT cores, which aligns with its higher power envelope. The architecture change from Ada Lovelace to Blackwell 2.0 is the primary differentiator, as the mobile part uses a newer design but with fewer resources.

The memory subsystems also reflect architectural choices. The RTX 4070 AD103 uses GDDR6X with a 192-bit bus, while the RTX 5070 Mobile uses GDDR7 with a 128-bit bus. The effective memory clock is 21 Gbps for the desktop and 24 Gbps for the mobile, but the wider bus on the desktop yields higher bandwidth. The API support is identical: both list DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The bus interface differs, with the desktop using PCIe 4.0 x16 and the mobile using PCIe 5.0 x16.

Specification Differences

The recorded specifications show clear differences in clock speeds. The RTX 4070 AD103 has a base clock of 1920 MHz and a boost clock of 2475 MHz. The RTX 5070 Mobile has a base clock of 907 MHz and a boost clock of 1425 MHz. The memory clock is 1313 MHz (21 Gbps effective) for the desktop and 1500 MHz (24 Gbps effective) for the mobile. These clock figures directly affect throughput metrics.

The pixel rate for the RTX 4070 AD103 is 158.4 GPixel/s, compared to 68.40 GPixel/s for the RTX 5070 Mobile. The texture rate is 455.4 GTexel/s versus 205.2 GTexel/s. FP32 and FP16 performance are both 29.15 TFLOPS for the desktop, while the mobile part delivers 13.13 TFLOPS for both. These numbers show that the desktop part is roughly 2.2 times faster in raw compute rates.

Power and physical design differ substantially. The RTX 4070 AD103 has a TDP of 200 W, a dual-slot width, and a 1x 16-pin power connector, with a suggested PSU of 550 W. The RTX 5070 Mobile has a TDP of 50 W, is listed as an IGP (integrated graphics processor), and has no power connectors or suggested PSU. The desktop dimensions are 240 mm in length, 110 mm in height, and 40 mm in width, while the mobile part has no recorded dimensions. Display outputs also differ: the desktop has 1x HDMI 2.1 and 3x DisplayPort 1.4a, while the mobile output is described as portable device dependent.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between these two GPUs. The winsA and winsB fields are both zero, and the headToHeadBenchmarks array is empty. This absence means that no direct comparison scores exist for the RTX 4070 AD103, as it has no benchmark entries. The RTX 5070 Mobile, however, has nine recorded benchmarks across various test suites.

The RTX 5070 Mobile’s benchmark scores include a Geekbench OpenCL score of 122,238 and a Vulkan score of 116,960. In PassMark tests, it scores 129 in DirectX 10, 192 in DirectX 11, 93 in DirectX 12, and 214 in DirectX 9. The G2D score is 896, the G3D score is 20,355, and the GPU compute score is 8,279. These results show that the mobile part performs strongest in the G3D test and in compute-heavy workloads, while its DirectX 12 score is the lowest among the recorded tests.

Since the RTX 4070 AD103 has no benchmark data, the comparison can only be made indirectly through the RTX 5070 Mobile’s nearest rivals. The mobile part’s average score of 29,928 places it within 0.1% of the RTX 3070 Ti, within 0.5% of the RTX 2080 Ti, and within 1.7% of the RX 6700. These rival scores are all from desktop GPUs, which suggests that the RTX 5070 Mobile, despite its 50 W TDP, delivers a level of performance comparable to those older high-end desktop cards.

Where Each One Wins

Based on the recorded data, the RTX 5070 Mobile wins in portability and power efficiency. Its 50 W TDP is one quarter of the desktop’s 200 W, and its IGP form factor means it requires no separate power connector. The mobile part also holds a higher percentile ranking at 75, compared to 50 for the desktop, and it has an active production status, whereas the RTX 4070 AD103 is end-of-life. The newer release date, 2025-04-14 versus 2024-02-29, and the newer Blackwell 2.0 architecture give the mobile part an edge in generation recency.

The RTX 4070 AD103 wins in raw performance specifications. Its FP32 throughput of 29.15 TFLOPS is more than double the mobile’s 13.13 TFLOPS. Its pixel rate of 158.4 GPixel/s and texture rate of 455.4 GTexel/s are similarly higher. The memory bandwidth of 504.2 GB/s exceeds the mobile’s 384.0 GB/s, and the 12 GB VRAM capacity is larger than the 8 GB on the mobile. The desktop also has higher clock speeds, more shading units, more RT cores, and more tensor cores. For workloads that depend on these metrics, such as high-resolution rendering or compute tasks, the desktop part is clearly superior on paper.

The use-case split is straightforward. The RTX 5070 Mobile is for systems where power draw and physical size matter, such as laptops, and its benchmark percentile indicates it performs well relative to the broader GPU population. The RTX 4070 AD103 is for desktop builds where the higher power draw is acceptable and where the user prioritizes maximum throughput metrics. The data does not show direct performance parity or superiority, so the choice hinges on form factor and the specific requirements of the workload. The mobile part’s average score of 29,928, with its close deltas to desktop rivals, suggests that it is a capable option for its class, but the desktop part’s specifications point to a higher ceiling in raw performance.
