NVIDIA GeForce RTX 3070 Ti vs NVIDIA GeForce RTX 4070 Mobile Comparison

The benchmark data presents a clear performance hierarchy between the NVIDIA GeForce RTX 3070 Ti and the NVIDIA GeForce RTX 4070 Mobile. The desktop-class RTX 3070 Ti wins all nine head-to-head comparisons, with an average benchmark score of 29,945 versus 27,435 for the mobile part. This places the RTX 3070 Ti in the 75th percentile of all GPUs, while the RTX 4070 Mobile sits in the 73rd percentile. The performance gap is consistent across every test category, though the magnitude varies significantly depending on the workload.

Head-to-Head Benchmarks

The largest victory for the RTX 3070 Ti comes in the Passmark G2D test, where it scores 1,055 against 763 for the RTX 4070 Mobile, a 38.3% advantage. This is closely followed by the Passmark GPU Compute test, where the desktop card delivers 11,601 points versus 8,399, a 38.1% delta. These two results indicate that the RTX 3070 Ti has a substantial edge in both 2D rasterization throughput and general-purpose compute workloads.

The Geekbench Vulkan test shows a 28.8% lead for the RTX 3070 Ti, with scores of 139,541 versus 108,367. This is a significant margin for a modern graphics API and suggests the desktop card handles Vulkan-optimized titles with considerably more headroom. The Passmark DirectX 10 test shows a 33.6% advantage (155 versus 116), while the DirectX 9 test reveals a 17% gap (261 versus 223).

The margins narrow considerably in the more modern DirectX 11 and DirectX 12 tests. The RTX 3070 Ti leads by 7.3% in DirectX 11 (192 versus 179) and by 7.1% in DirectX 12 (91 versus 85). These are the closest results in the entire comparison, indicating that the RTX 4070 Mobile’s Ada Lovelace architecture narrows the gap when running current-generation game engines. The Geekbench OpenCL test shows a 9.6% advantage for the RTX 3070 Ti (119,718 versus 109,197), and the Passmark G3D test shows a 19.2% lead (23,356 versus 19,587).

When placed against its nearest rivals, the RTX 3070 Ti’s average score of 29,945 is essentially tied with the RTX 5070 Mobile (29,928, a 0.1% delta) and the RTX 2080 Ti (29,783, a 0.5% delta). It trails the AMD Radeon RX 6800 by 0.5% (30,095) and the Radeon RX 6700 by 1.6% (30,433). The RTX 4070 Mobile’s average of 27,435 is dead even with the Radeon RX 6700 XT (27,425, a 0% delta), while it sits 0.5% behind the RTX 3090 (27,565) and 1.5% behind the Radeon Pro Vega 20 (27,839).

Where Each One Wins

The RTX 3070 Ti wins decisively in legacy and compute-oriented workloads. Its 38.3% lead in Passmark G2D and 38.1% lead in GPU Compute make it the clear choice for tasks that stress raw shading throughput or 2D acceleration. The 28.8% Vulkan advantage further cements its position for applications and games that rely on Vulkan’s low-level access. The desktop card also dominates in DirectX 10 (33.6% ahead) and DirectX 9 (17% ahead), making it the better option for older game libraries.

The RTX 4070 Mobile’s strengths are relative rather than absolute. Its narrowest deficits come in the DirectX 11 and DirectX 12 tests, where it trails by only 7.3% and 7.1%, respectively. This indicates that the Ada Lovelace architecture’s newer feature set and efficiency improvements partially offset the raw hardware disadvantage. The mobile card’s smaller gap in these modern APIs suggests that for current-generation titles, the performance difference is far less pronounced than in older or compute-heavy workloads.

The RTX 4070 Mobile’s 73rd percentile ranking versus the RTX 3070 Ti’s 75th percentile shows that both cards sit in the upper-midrange of the GPU landscape. However, the desktop card’s nearest rivals include the RTX 5070 Mobile and RTX 2080 Ti, while the mobile card’s nearest rivals are the RX 6700 XT and RTX 3090. This means the RTX 3070 Ti competes with newer mobile flagships, while the RTX 4070 Mobile is positioned against previous-generation desktop flagships.

Specification Differences

The two GPUs differ across nearly every core specification. The RTX 3070 Ti uses a GA104 chip with 6,144 shading units, 192 texture mapping units, and 96 raster output units. The RTX 4070 Mobile uses an AD106 chip with 4,608 shading units, 144 TMUs, and 48 ROPs. The desktop card also has more ray tracing cores (48 versus 36) and more tensor cores (192 versus 144).

Memory configurations diverge significantly. The RTX 3070 Ti features 8 GB of GDDR6X on a 256-bit bus with 608.3 GB/s bandwidth, while the RTX 4070 Mobile has 8 GB of GDDR6 on a 128-bit bus with 256.0 GB/s bandwidth. The clock speeds also differ: the RTX 3070 Ti has a base clock of 1575 MHz and boost of 1770 MHz, while the RTX 4070 Mobile operates at 1395 MHz base and 1695 MHz boost. The memory clock is 1188 MHz (19 Gbps effective) for the desktop card versus 2000 MHz (16 Gbps effective) for the mobile part.

The compute throughput figures reflect these differences. The RTX 3070 Ti delivers 21.75 TFLOPS of FP32 and FP16 performance, while the RTX 4070 Mobile delivers 15.62 TFLOPS in both. Pixel rate is 169.9 GPixel/s versus 81.36 GPixel/s, and texture rate is 339.8 GTexel/s versus 244.1 GTexel/s. The power draw is 290 W for the desktop card versus 115 W for the mobile part.

Architecture Differences

The RTX 3070 Ti is built on Samsung’s 8 nm process node and uses the Ampere architecture. It contains 17,400 million transistors on a 392 mm² die, resulting in a transistor density of 44.4 million per mm². The RTX 4070 Mobile uses TSMC’s 5 nm node and the Ada Lovelace architecture, packing 22,900 million transistors into a 188 mm² die with a density of 121.8 million per mm². This means the mobile chip has 31.6% more transistors in less than half the die area.

The physical form factors are entirely different. The RTX 3070 Ti is a dual-slot desktop card measuring 267 mm (10.5 inches) in length and 112 mm (4.4 inches) in height, with a 1x 12-pin power connector and a suggested PSU of 600 W. The RTX 4070 Mobile is an integrated graphics processor with no dedicated power connectors and no published dimensions. The desktop card uses a PCIe 4.0 x16 interface, while the mobile part uses PCIe 4.0 x8. Display outputs also differ: the RTX 3070 Ti offers 1x HDMI 2.1 and 3x DisplayPort 1.4a, while the RTX 4070 Mobile’s outputs are portable device dependent.

The production status and release timing differ as well. The RTX 3070 Ti was released on May 30, 2021, has a launch MSRP of 599 USD for the desktop card, and is now end-of-life. The RTX 4070 Mobile was released on January 2, 2023, has no launch MSRP listed, and remains active in production. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

The Verdict

The data clearly favors the RTX 3070 Ti for raw performance. It wins every benchmark, with an average score 9.1% higher than the RTX 4070 Mobile. For users prioritizing compute workloads, legacy DirectX titles, or Vulkan-based applications, the desktop card offers advantages ranging from 17% to 38.3%. Its 75th percentile ranking and competitive position against the RTX 5070 Mobile and RTX 2080 Ti further reinforce its performance credentials.

The RTX 4070 Mobile’s case rests on efficiency and relevance. Its 115 W power draw is less than half the RTX 3070 Ti’s 290 W, and its 5 nm TSMC process with 121.8 million transistors per mm² represents a newer, denser architecture. The narrow 7.1% to 7.3% gaps in DirectX 11 and DirectX 12 suggest that in modern gaming scenarios, the mobile chip is not far behind. Its 73rd percentile ranking and statistical tie with the RX 6700 XT show it remains a capable performer.

The choice depends on the use case. The RTX 3070 Ti is the superior option for desktop builds where power and space constraints are secondary, particularly for compute-heavy or legacy software workloads. The RTX 4070 Mobile is the appropriate choice for portable systems where the 115 W power envelope and integrated form factor are prerequisites, especially when the primary workload is modern DirectX 12 gaming. The data shows no scenario where the mobile card outperforms the desktop part, but its efficiency and newer architecture make it a rational pick for laptop configurations.
