NVIDIA GeForce RTX 4070 Ti SUPER vs NVIDIA GeForce RTX 5070 Ti Mobile Comparison

Head-to-Head Benchmarks

The recorded data paints a lopsided picture at first glance, but the single victory for the mobile part is the most striking result in the entire comparison. The NVIDIA GeForce RTX 5070 Ti Mobile wins only one of the nine head-to-head tests, yet that win is a landslide. In Geekbench Vulkan, the mobile GPU scores 139,213 against the RTX 4070 Ti SUPER's 53,683, a delta of 159.3% in favor of the newer architecture. That is not a marginal edge; it is a doubling of the score and then some. The Vulkan result suggests the Blackwell 2.0 architecture has a fundamentally different relationship with low-level graphics APIs, one that the Ada Lovelace part cannot match regardless of its other advantages.

Every other benchmark in the head-to-head set goes to the RTX 4070 Ti SUPER. The largest margin is in Passmark GPU Compute, where the desktop card scores 18,372 versus 10,101 for the mobile chip, a 45% gap. That is the single biggest deficit for the RTX 5070 Ti Mobile across all tests, and it aligns with the raw compute resources each part brings. The desktop GPU also leads by 28.1% in Passmark DirectX 9 (360 vs 259) and by 27.8% in Geekbench OpenCL (199,267 vs 143,870). The OpenCL result is notable because it is one of the few tests where both parts use the same API, and the gap is nearly identical to the DirectX 9 margin, which suggests a consistent raw throughput disadvantage for the mobile chip rather than an API-specific quirk.

The remaining wins for the RTX 4070 Ti SUPER are more moderate but still decisive. Passmark G3D shows 31,811 versus 24,004, a 24.5% lead. DirectX 10, DirectX 11, and DirectX 12 margins sit at 16.6%, 14.7%, and 14.3% respectively, with scores of 181 vs 151, 278 vs 237, and 119 vs 102. The 2D test is close in absolute terms (1,225 vs 981) but still represents a 19.9% advantage for the desktop part. Across all nine tests, the RTX 4070 Ti SUPER wins eight, with the RTX 5070 Ti Mobile taking only the Vulkan test. The average benchmark score for the desktop card is 31,087, while the mobile part averages 35,435, a reversal that is explained entirely by the Vulkan outlier pulling the mobile average upward. The percentile ranks tell a similar story: the RTX 5070 Ti Mobile sits at the 80th percentile of all GPUs, while the RTX 4070 Ti SUPER sits at the 76th, so the aggregate position favors the mobile chip even though the desktop card wins most individual tests.

Architecture Differences

The two GPUs come from different generations and different design philosophies. The RTX 5070 Ti Mobile uses the GB205 chip on Blackwell 2.0 architecture, built on a 5 nm process at TSMC with 31,100 million transistors on a 263 mm² die. The RTX 4070 Ti SUPER uses the AD103 chip on Ada Lovelace, also on a 5 nm TSMC process, but with 45,900 million transistors on a 379 mm² die. The desktop part is physically larger and denser, with 121.1M transistors per mm² versus 118.3M per mm² for the mobile chip. That density difference is small, but the raw transistor count difference is enormous: the RTX 4070 Ti SUPER has nearly 48% more transistors to work with.

The compute resources reflect that gap. The RTX 4070 Ti SUPER has 8,448 shading units, 264 TMUs, 96 ROPs, 66 RT cores, and 264 tensor cores. The RTX 5070 Ti Mobile has 5,888 shading units, 184 TMUs, 80 ROPs, 46 RT cores, and 184 tensor cores. In every count, the desktop card leads, and the margins are substantial: 43% more shading units, 43% more TMUs, 20% more ROPs, 43% more RT cores, and 43% more tensor cores. The FP32 throughput tells the same story, with the RTX 4070 Ti SUPER delivering 44.10 TFLOPS versus 17.04 TFLOPS for the mobile part. That is a 2.6x raw compute advantage for the desktop GPU, which explains the consistent lead in OpenCL, DirectX, and compute benchmarks.

Memory configuration also differs sharply. The RTX 4070 Ti SUPER has 16 GB of GDDR6X on a 256-bit bus, with bandwidth of 672.3 GB/s. The RTX 5070 Ti Mobile has 12 GB of GDDR7 on a 192-bit bus, with bandwidth of 672.0 GB/s. The bandwidth is nearly identical, which is a remarkable convergence given the different memory types and bus widths. The newer GDDR7 memory runs at 1750 MHz (28 Gbps effective) versus 1313 MHz (21 Gbps effective) for GDDR6X, and the mobile part compensates for its narrower bus with faster memory clocks. The capacity difference remains, though: 16 GB versus 12 GB is a 33% advantage for the desktop card in VRAM capacity.

Clock speeds are where the mobile part falls behind most visibly. The RTX 4070 Ti SUPER runs at a base clock of 2340 MHz and a boost clock of 2610 MHz, while the RTX 5070 Ti Mobile runs at 847 MHz base and 1447 MHz boost. The desktop card's boost clock is 80% higher than the mobile part's boost clock. This is the direct consequence of power constraints: the RTX 4070 Ti SUPER has a TDP of 285 W and requires a 600 W power supply with a single 16-pin connector, while the RTX 5070 Ti Mobile has a TDP of 60 W and no power connectors at all, drawing everything from an integrated package. The mobile part is an IGP, meaning it is designed to live inside a laptop with no discrete power delivery, and that constraint forces the clocks down to a fraction of the desktop part's speeds.

The bus interface also differs: the RTX 5070 Ti Mobile uses PCIe 5.0 x16, while the RTX 4070 Ti SUPER uses PCIe 4.0 x16. The newer standard offers more bandwidth for data transfers, though the benchmark data does not show this translating into a general performance advantage. The display outputs differ as well: the mobile part is portable-device dependent, while the desktop card offers 1x HDMI 2.1 and 3x DisplayPort 1.4a. The desktop part is a triple-slot card measuring 310 mm by 140 mm by 61 mm, while the mobile part has no listed dimensions because it is an integrated component.

The Verdict

The data does not support a simple winner. The RTX 5070 Ti Mobile wins the Vulkan test by 159.3%, which is not a small anomaly but a fundamental architectural advantage in that API. The RTX 4070 Ti SUPER wins eight tests, with margins ranging from 14.3% to 45%. The average benchmark score favors the mobile part (35,435 vs 31,087), but that average is skewed by the extreme Vulkan result. The percentile ranks are close: 80th for the mobile chip versus 76th for the desktop card.

For raw compute and traditional DirectX workloads, the RTX 4070 Ti SUPER is the clear choice. Its 44.10 TFLOPS FP32 throughput versus 17.04 TFLOPS, its 8,448 shading units versus 5,888, and its 16 GB versus 12 GB of VRAM all point in the same direction. The desktop card also benefits from a 285 W power budget versus 60 W, and the clock speeds reflect that. Anyone running OpenCL workloads, DirectX 9 through 12 titles, or compute-heavy tasks should look at the RTX 4070 Ti SUPER, which leads by 14% to 45% across those tests.

For Vulkan-based applications, the RTX 5070 Ti Mobile is the standout. The 159.3% lead in Geekbench Vulkan is the largest margin in any test, and it suggests that Blackwell 2.0 handles Vulkan's low-level execution model far more efficiently than Ada Lovelace. The mobile part also draws only 60 W, making it viable in thin laptops where the RTX 4070 Ti SUPER's 285 W TDP and triple-slot cooler would be impossible. The RTX 5070 Ti Mobile is production-active, while the RTX 4070 Ti SUPER is end-of-life, which matters for long-term driver support and availability.

The specification data shows a desktop card with more of everything except memory bandwidth and API efficiency. The RTX 4070 Ti SUPER has more transistors, more shading units, more RT cores, more tensor cores, more VRAM, and higher clocks. The RTX 5070 Ti Mobile has faster memory, a newer PCIe interface, a newer architecture, and a dramatically lower power draw. Neither part replaces the other; they serve different physical and software contexts.

Where Each One Wins

The RTX 4070 Ti SUPER dominates in every compute-oriented and legacy graphics workload in the recorded data. Its Passmark GPU Compute score of 18,372 versus 10,101 is the largest margin, and it also wins OpenCL (199,267 vs 143,870), DirectX 9 (360 vs 259), DirectX 10 (181 vs 151), DirectX 11 (278 vs 237), DirectX 12 (119 vs 102), G2D (1,225 vs 981), and G3D (31,811 vs 24,004). The desktop card's 44.10 TFLOPS FP32 throughput and 285 W power budget make it the obvious pick for rendering, compute, and conventional DirectX gaming.

The RTX 5070 Ti Mobile wins only in Vulkan, but that win is so large that it defines the part's identity. The 139,213 score against 53,683 represents a 159.3% advantage, and it indicates that Blackwell 2.0's architecture is dramatically better suited to Vulkan's explicit execution model. The mobile part also wins on efficiency: 60 W TDP versus 285 W, no power connectors versus a 16-pin connector, and an IGP form factor versus a triple-slot card. For laptops, thin-and-light builds, or any scenario where power draw and physical size matter, the RTX 5070 Ti Mobile is the only viable option of the two. The mobile part also uses GDDR7 memory and PCIe 5.0, which are newer standards than the desktop card's GDDR6X and PCIe 4.0.
