The Passmark G3D test, typically representative of overall 3D rendering performance, gives the RTX 5070 Ti Mobile a score of 24004 against 19587 for the RTX 4070 Mobile, a -18.4% delta. The 2D graphics test (Passmark G2D) shows 981 versus 763, a -22.2% delta, indicating that even in less GPU-intensive tasks, the newer part maintains a substantial lead.

The average benchmark score confirms the overall picture. The RTX 5070 Ti Mobile averages 35435 across all recorded tests, while the RTX 4070 Mobile averages 27435. The percentile rankings place the RTX 5070 Ti Mobile at the 80th percentile against all GPUs in the database, while the RTX 4070 Mobile sits at the 73rd percentile. This seven-point percentile gap reflects the consistent performance difference across the test suite.

Where Each One Wins

The RTX 5070 Ti Mobile wins every benchmark category in the recorded data. Its strengths are most pronounced in compute-heavy workloads. The Geekbench OpenCL score of 143870 and Vulkan score of 139213 suggest strong general-purpose compute capability. The Passmark GPU compute score of 10101 reinforces this pattern, showing a -16.8% advantage over the RTX 4070 Mobile.

The RTX 5070 Ti Mobile also dominates in legacy DirectX tests. Its DirectX 9 score of 259 and DirectX 10 score of 151 show particularly large margins over the RTX 4070 Mobile's 223 and 116 respectively. This suggests the newer architecture handles older API paths efficiently, not just modern workloads.

The RTX 4070 Mobile shows no benchmark categories where it leads. However, its closest relative performance appears in the DirectX 12 test, where the delta is -16.7%, and the GPU compute test at -16.8%. The DirectX 9 test shows the smallest overall gap at -13.9%. This indicates that in certain API-specific workloads, the RTX 4070 Mobile comes closest to matching its successor.

The RTX 5070 Ti Mobile maintains a consistent advantage across memory bandwidth, which likely contributes to its benchmark performance. The RTX 4070 Mobile uses 8 GB of GDDR6 memory on a 128-bit bus with 256.0 GB/s bandwidth. The RTX 5070 Ti Mobile uses 12 GB of GDDR7 memory on a 192-bit bus with 672.0 GB/s bandwidth. The memory bandwidth difference is substantial, with the newer part delivering over 2.6 times the bandwidth of the older part.

The Verdict

The data indicates that the NVIDIA GeForce RTX 5070 Ti Mobile is the superior performer in every recorded benchmark. The average benchmark score of 35435 versus 27435 represents a roughly 29% advantage for the RTX 5070 Ti Mobile. The percentile ranking of 80 versus 73 confirms that the newer part sits higher in the overall GPU distribution.

The RTX 5070 Ti Mobile nearest rival data places it alongside the NVIDIA Quadro GV100, which scores 35520 with a -0.2% delta, meaning the RTX 5070 Ti Mobile trails that workstation card by a negligible margin. The RTX 4070 Mobile's nearest rival is the AMD Radeon RX 6700 XT at 27425 with a 0% delta, placing it in a completely different performance tier.

For users selecting between these two mobile GPUs, the RTX 5070 Ti Mobile delivers higher scores across all nine benchmark tests. The RTX 4070 Mobile remains competitive in specific API tests but cannot match the newer part's overall performance envelope. The RTX 5070 Ti Mobile also offers a higher shading unit count (5888 versus 4608), more texture mapping units (184 versus 144), more render output units (80 versus 48), more ray tracing cores (46 versus 36), and more tensor cores (184 versus 144).

The RTX 4070 Mobile contains 22,900 million transistors on a 188 mm² die, giving a transistor density of 121.8M per mm². The RTX 5070 Ti Mobile contains 31,100 million transistors on a 263 mm² die, with a density of 118.3M per mm². The newer chip packs substantially more transistors, though the density is slightly lower due to the larger die area.

The memory subsystem represents one of the most significant architectural differences. The RTX 4070 Mobile uses GDDR6 memory at 2000 MHz with 16 Gbps effective speed, providing 256.0 GB/s bandwidth across a 128-bit bus. The RTX 5070 Ti Mobile uses GDDR7 memory at 1750 MHz with 28 Gbps effective speed, delivering 672.0 GB/s bandwidth across a 192-bit bus. The newer memory type and wider bus give the RTX 5070 Ti Mobile a major bandwidth advantage.

The compute configuration favors the RTX 5070 Ti Mobile in every category. The RTX 4070 Mobile has 4608 shading units, 144 TMUs, 48 ROPs, 36 ray tracing cores, and 144 tensor cores. The RTX 5070 Ti Mobile has 5888 shading units, 184 TMUs, 80 ROPs, 46 ray tracing cores, and 184 tensor cores. This translates to higher pixel rate (115.8 GPixel/s versus 81.36 GPixel/s), higher texture rate (266.2 GTexel/s versus 244.1 GTexel/s), and higher FP32 throughput (17.04 TFLOPS versus 15.62 TFLOPS). Both GPUs support FP16 at a 1:1 ratio with FP32.

The power characteristics differ notably. The RTX 4070 Mobile has a TDP of 115 W, while the RTX 5070 Ti Mobile has a TDP of 60 W despite delivering higher performance. Both use an integrated graphics processor (IGP) slot width with no power connectors. The bus interface also differs: the RTX 4070 Mobile uses PCIe 4.0 x8, while the RTX 5070 Ti Mobile uses PCIe 5.0 x16.

Both GPUs support the same API set: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The display outputs are listed as portable device dependent for both. The RTX 4070 Mobile was released in January 2023, while the RTX 5070 Ti Mobile was released in February 2025.
