NVIDIA GeForce RTX 3070 Mobile vs NVIDIA GeForce RTX 3070 Ti Mobile Comparison

Both GPUs are built on the same Ampere architecture, the GA104 chip, and the Samsung 8 nm process, but they are configured with different silicon budgets. The RTX 3070 Ti Mobile carries 5888 shading units, 184 TMUs, 96 ROPs, 46 RT cores, and 184 tensor cores, while the RTX 3070 Mobile uses 5120 shading units, 160 TMUs, 80 ROPs, 40 RT cores, and 160 tensor cores. The Ti model also has higher boost clocks at 1410 MHz versus 1560 MHz for the non-Ti, though its base clock is lower at 915 MHz versus 1110 MHz. Both share the same 8 GB GDDR6 memory on a 256-bit bus, producing identical 448.0 GB/s bandwidth, and both are rated at a 115 W TDP. The additional cores and clock differences translate directly into performance deltas, with the Ti winning all recorded benchmark comparisons.

Head-to-Head Benchmarks

The recorded data shows a clean sweep for the RTX 3070 Ti Mobile across all ten head-to-head tests. The largest single delta appears in the Passmark DirectX 9 test, where the Ti scores 196 against 160 for the non-Ti, a 22.5% advantage. This is closely followed by the Passmark G2D test, which shows a 22.2% delta with scores of 783 versus 641. The Ti also leads by 15.8% in the Passmark G3D test, posting 17,727 points to the non-Ti's 15,309. These three results indicate that the Ti's extra execution resources provide a substantial uplift in both legacy DirectX 9 workloads and general 2D performance, not just modern API scenarios.

In modern API benchmarks, the Ti maintains a meaningful but slightly narrower margin. The Geekbench Vulkan test shows a 15.3% delta, with the Ti scoring 100,027 against 86,768. The Geekbench OpenCL test yields a 14.1% delta, with scores of 106,022 versus 92,939. The 3DMark Steel Nomad DX12 test shows the smallest overall delta at 8.1%, with the Ti scoring 2,572 against 2,380. The Passmark DirectX 12 test shows a 14.1% delta (73 versus 64), while the DirectX 11 test shows a 10.9% delta (153 versus 138). The DirectX 10 test shows a 9.7% delta (124 versus 113). The Passmark GPU Compute test rounds out the list with a 9.9% delta (7,504 versus 6,827).

The average benchmark score tells a similar story. The RTX 3070 Ti Mobile has an average score of 23,518, while the RTX 3070 Mobile averages 20,534. This puts the Ti roughly 14.5% ahead in aggregate terms. The Ti also sits at the 69th percentile among all GPUs, compared to the 65th percentile for the non-Ti. The Ti's nearest rival in the database is the NVIDIA GeForce RTX 3080 Mobile, with an average score of 23,628, which is 0.5% higher than the Ti. The AMD Radeon AI PRO R9700 trails the Ti by 0.9%, and the NVIDIA GeForce GTX TITAN Z is 0.9% behind. The AMD Radeon R9 M290X is 1% behind. The non-Ti, by contrast, sits within 0.6% of the Intel Arc B570, Intel Arc A750, and AMD Radeon R9 M390X, and it leads the NVIDIA Quadro M4000M by 0.3%.

Where Each One Wins

Given that the RTX 3070 Ti Mobile wins every recorded benchmark, the use-case split is straightforward. The Ti is the stronger choice for any workload that stresses raw rasterization, compute throughput, or API-specific features. The 22.5% lead in DirectX 9 suggests that older titles or applications that rely on legacy rendering paths will see the largest benefit from the Ti. The 22.2% lead in G2D indicates better 2D performance, which can matter for desktop composition, video playback, and general UI responsiveness, though the absolute scores in that test are low compared to 3D workloads.

The 15.8% lead in Passmark G3D and the 15.3% lead in Vulkan show that the Ti is also well suited for modern gaming and GPU-accelerated compute. The 14.1% lead in OpenCL and the 14.1% lead in DirectX 12 reinforce this pattern, suggesting that the Ti's extra shader and tensor cores are fully utilized in heterogeneous compute environments. The 8.1% lead in 3DMark Steel Nomad DX12 is the smallest relative margin, but it still represents a clear win for the Ti in a demanding modern DirectX 12 workload. The 9.9% lead in GPU compute and the 9.7% lead in DirectX 10 round out the picture: the Ti is consistently ahead, but the margin narrows in some newer API paths.

The non-Ti, with no wins in any recorded test, does not offer a specific scenario where it is the better performer. However, the data shows that it is not a weak GPU in isolation. Its average score of 20,534 places it at the 65th percentile, and its nearest rivals are all within 0.6% of its aggregate score. In absolute terms, the non-Ti still delivers strong performance, but the Ti is unequivocally the faster part in every measured category.

The Verdict

From the recorded data, the NVIDIA GeForce RTX 3070 Ti Mobile is the superior GPU for any user who prioritizes maximum performance. It wins all ten head-to-head benchmarks, with deltas ranging from 8.1% to 22.5%. The Ti's average benchmark score of 23,518 is 14.5% higher than the non-Ti's 20,534, and it sits at a higher percentile ranking. Users who run DirectX 9 titles, 2D applications, or OpenCL workloads will see the biggest gains from choosing the Ti, with deltas above 14% in those categories.

The non-Ti remains a capable mobile GPU, but it is clearly positioned below the Ti in this comparison. Its own nearest rival list includes the Intel Arc B570 and Arc A750, which are within 0.2% of its average score, indicating that it competes with a different tier of hardware. For users who already own a laptop with the non-Ti, the data suggests it is still a solid performer, but there is no benchmark where it outpaces the Ti.

The final choice depends on whether the user needs the extra performance. The Ti offers a consistent double-digit uplift in most tests, and even the smallest margin, 8.1% in 3DMark Steel Nomad DX12, is a meaningful improvement. The non-Ti does not offer any countervailing advantage in the database, no lower TDP, no different memory configuration, and no API feature that the Ti lacks. Both GPUs support the same DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4 APIs. The Ti is the better pick for anyone who wants the highest frame rates and compute throughput available in this pairing.

Architecture Differences

Both GPUs are based on the same GA104 chip, using the Ampere architecture and the Samsung 8 nm process. The die size is identical at 392 mm², with 17,400 million transistors and a transistor density of 44.4M per mm². The fundamental difference lies in how many of those transistors are enabled. The RTX 3070 Ti Mobile enables 5888 shading units, 184 TMUs, 96 ROPs, 46 RT cores, and 184 tensor cores. The RTX 3070 Mobile disables some of these resources, leaving 5120 shading units, 160 TMUs, 80 ROPs, 40 RT cores, and 160 tensor cores. This represents a 15% reduction in shading units, TMUs, and tensor cores, and a 16.7% reduction in RT cores and ROPs.

Clock speeds also differ, but not in a simple upward direction. The RTX 3070 Ti Mobile has a base clock of 915 MHz and a boost clock of 1410 MHz. The RTX 3070 Mobile has a higher base clock of 1110 MHz and a higher boost clock of 1560 MHz. Despite the higher clocks on the non-Ti, the Ti's larger core count gives it higher aggregate throughput. The Ti's pixel rate is 135.4 GPixel/s versus 124.8 GPixel/s for the non-Ti, and its texture rate is 259.4 GTexel/s versus 249.6 GTexel/s. The FP32 and FP16 performance figures are 16.60 TFLOPS for the Ti and 15.97 TFLOPS for the non-Ti, with both running at a 1:1 ratio.

Both GPUs share the same memory subsystem: 8 GB of GDDR6 on a 256-bit bus, yielding 448.0 GB/s bandwidth. Both are rated at a 115 W TDP, and both use a PCIe 4.0 x16 bus interface. The display outputs are listed as portable device dependent, and neither GPU requires external power connectors. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The production status for both is end-of-life, with the non-Ti releasing earlier in 2021 and the Ti releasing in early 2022. Both are successors to the GeForce 20 Mobile series, and neither has a listed successor in the database.
