NVIDIA GeForce RTX 4070 vs NVIDIA GeForce RTX 5070 Mobile Comparison

The Verdict

The data in the database positions the NVIDIA GeForce RTX 4070 as the unequivocally stronger performer in this comparison. Across all nine recorded head-to-head benchmarks, the RTX 4070 secures the win, with the RTX 5070 Mobile not claiming a single victory. The average benchmark score for the RTX 4070 is 37,648, placing it in the 81st percentile of all GPUs, while the RTX 5070 Mobile averages 29,928, sitting in the 75th percentile. This is a substantial overall gap of roughly 25.8 percent between the two average scores.

The RTX 4070 is a desktop card that has reached end-of-life status, whereas the RTX 5070 Mobile is an active mobile part. The RTX 5070 Mobile is a low-power integrated graphics processor with a 50 W TDP, designed for portability, while the RTX 4070 is a dual-slot desktop card with a 200 W TDP and a dedicated 16-pin power connector. Benchmark results indicate that the RTX 4070 is the choice for users who prioritize raw performance and do not require portability. The RTX 5070 Mobile, despite being from the newer GeForce 50-series generation, delivers lower scores across every test in the database. The recorded data does not show any scenario where the RTX 5070 Mobile wins, so its suitability is limited to systems where the low power draw and integrated form factor are the primary requirements.

Architecture Differences

The two GPUs come from different generations and use distinct architectures. The RTX 4070 uses the AD104 chip based on the Ada Lovelace architecture, belonging to the GeForce 40-series. The RTX 5070 Mobile uses the GB206 chip based on the Blackwell 2.0 architecture, belonging to the GeForce 50 Mobile series. Both are manufactured on a 5 nm process at TSMC, but the chip sizes differ significantly. The RTX 4070 has a die size of 294 mm² and contains 35,800 million transistors, resulting in a transistor density of 121.8 million per mm². The RTX 5070 Mobile has a smaller die at 181 mm² with 21,900 million transistors, giving a density of 121.0 million per mm².

The memory subsystems also show clear architectural splits. The RTX 4070 uses 12 GB of GDDR6X memory on a 192-bit bus, delivering a bandwidth of 504.2 GB/s. The RTX 5070 Mobile uses 8 GB of GDDR7 memory on a 128-bit bus, providing 384.0 GB/s of bandwidth. The memory clocks differ as well: the RTX 4070 runs at an effective 21 Gbps, while the RTX 5070 Mobile runs at an effective 24 Gbps. The newer GDDR7 standard in the RTX 5070 Mobile offers a higher per-pin data rate, but the narrower bus and smaller capacity result in lower overall bandwidth.

The compute resources are heavily weighted toward the RTX 4070. It features 5,888 shading units, 184 texture mapping units, 64 ROPs, 46 ray tracing cores, and 184 tensor cores. The RTX 5070 Mobile has 4,608 shading units, 144 TMUs, 48 ROPs, 36 ray tracing cores, and 144 tensor cores. The pixel rate of the RTX 4070 is 158.4 GPixel/s, and its texture rate is 455.4 GTexel/s. The RTX 5070 Mobile manages 68.40 GPixel/s and 205.2 GTexel/s. The FP32 and FP16 performance figures are identical within each card, with the RTX 4070 delivering 29.15 TFLOPS and the RTX 5070 Mobile delivering 13.13 TFLOPS.

Both cards support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The bus interfaces differ, with the RTX 4070 using PCIe 4.0 x16 and the RTX 5070 Mobile using PCIe 5.0 x16. The display outputs also vary: the RTX 4070 provides 1x HDMI 2.1 and 3x DisplayPort 1.4a, while the RTX 5070 Mobile is described as "Portable Device Dependent" with no fixed output configuration.

Where Each One Wins

The RTX 4070 wins in every recorded category. Its largest advantage appears in compute-heavy workloads. In the Passmark GPU Compute test, the RTX 4070 scores 14,720 against 8,279 for the RTX 5070 Mobile, a delta of 77.8 percent. This indicates a major lead in general-purpose compute performance, which can benefit tasks like rendering, physics simulations, and other non-graphics workloads.

The RTX 4070 also shows a decisive edge in legacy DirectX performance. The Passmark DirectX 9 test shows a 49.5 percent delta (320 vs 214), and the DirectX 11 test shows a 27.1 percent delta (244 vs 192). These older APIs often respond well to raw shader throughput, and the RTX 4070 has more than double the FP32 compute of the RTX 5070 Mobile.

For modern graphics workloads, the RTX 4070 still leads, but the margins vary. The Geekbench Vulkan test shows a 48.9 percent delta (174,152 vs 116,960), while the Geekbench OpenCL test shows a 26.7 percent delta (154,858 vs 122,238). The Passmark DirectX 12 test shows a smaller lead of 10.8 percent (103 vs 93), suggesting that the newer API narrows the gap somewhat, but the RTX 4070 remains ahead.

The RTX 5070 Mobile has no benchmark wins. Its only advantages in the database are structural: it is an integrated part with a 50 W TDP, it uses the newer Blackwell 2.0 architecture, it has a PCIe 5.0 interface, and it uses GDDR7 memory. These features do not translate into superior scores in the recorded tests. The RTX 5070 Mobile would be the logical choice in a system where power consumption and physical footprint are the dominant constraints, but the performance data does not favor it in any measured workload.

Head-to-Head Benchmarks

The head-to-head data shows a clean sweep for the RTX 4070, but the margins are not uniform across tests. The largest delta is in the Passmark GPU Compute test, where the RTX 4070 scores 14,720 versus 8,279, a 77.8 percent advantage. This is a massive gap and highlights the RTX 4070's superior raw compute throughput, likely driven by its higher shading unit count and more than double the FP32 performance.

The second-largest delta appears in the Passmark DirectX 9 test, with the RTX 4070 scoring 320 against 214, a 49.5 percent lead. The Geekbench Vulkan test follows closely, with the RTX 4070 at 174,152 and the RTX 5070 Mobile at 116,960, a 48.9 percent delta. Vulkan is a modern low-level API, so this result indicates that the RTX 4070's advantage extends beyond legacy workloads.

The Passmark G3D test shows a 32.3 percent delta (26,927 vs 20,355), which is a broad measure of 3D graphics performance. The Passmark G2D test shows a 29.9 percent delta (1,164 vs 896), indicating a lead in 2D operations as well. The Geekbench OpenCL test shows a 26.7 percent delta (154,858 vs 122,238), and the Passmark DirectX 11 test shows a 27.1 percent delta (244 vs 192).

The smallest deltas are in the DirectX 10 and DirectX 12 tests. The DirectX 10 test shows a 7.8 percent delta (139 vs 129), and the DirectX 12 test shows a 10.8 percent delta (103 vs 93). While these are still wins for the RTX 4070, the closer margins suggest that the newer APIs and the RTX 5070 Mobile's GDDR7 memory help it stay relatively competitive in these specific tests. Still, the overall pattern is consistent: the RTX 4070 delivers higher scores across all recorded metrics, from legacy DirectX 9 to modern Vulkan and compute workloads.
