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

The NVIDIA GeForce RTX 4070 Ti SUPER and the NVIDIA GeForce RTX 5070 Mobile occupy very different corners of the GPU landscape, one a desktop behemoth and the other a laptop part. The head-to-head benchmark data reveals a stark performance split, with the desktop card winning eight of nine tests, yet the mobile chip claiming a single, surprising victory. This comparison is less about a close contest and more about understanding the architectural and design philosophy shifts between the Ada Lovelace and Blackwell 2.0 generations.

Head-to-Head Benchmarks

The most lopsided result in the entire comparison is in the Passmark GPU Compute test. Here, the RTX 4070 Ti SUPER scores 18,372 against the RTX 5070 Mobile's 8,279, a staggering 121.9% advantage. This massive delta strongly suggests the desktop part's raw compute throughput, driven by its 8,448 shading units and 44.10 TFLOPS of FP32 performance, is in a completely different league than the mobile chip's 4,608 shading units and 13.13 TFLOPS. The data indicates that for any workload that leverages raw shader processing, such as GPU-accelerated rendering or scientific computation, the desktop card is the definitive choice.

Following closely behind is the DirectX 9 benchmark, where the RTX 4070 Ti SUPER scores 360 versus the mobile's 214, a 68.2% difference. This pattern continues across the older DirectX APIs. In DirectX 11, the desktop card leads with a score of 278 compared to 192, a 44.8% advantage. Even in the more modern DirectX 12 test, the 4070 Ti SUPER maintains a clear lead, scoring 119 against the 5070 Mobile's 93, a 28% margin. This consistent advantage across API generations shows that the desktop GPU's superior pixel and texture rates—250.6 GPixel/s and 689.0 GTexel/s versus 68.40 GPixel/s and 205.2 GTexel/s—provide a fundamental performance edge that is not tied to any specific software layer.

The Geekbench OpenCL result further cements the desktop card's dominance, with the 4070 Ti SUPER scoring 199,267 compared to the mobile's 122,238, a 63% difference. This is a more synthetic test, but the result aligns with the compute lead seen elsewhere. The Passmark G3D (DirectX) score, which is often a good proxy for overall gaming performance, shows the desktop part winning 31,811 to 20,355, a 56.3% margin. This translates to a significant real-world performance disparity in graphics-intensive applications.

The RTX 4070 Ti SUPER also wins the less glamorous tests. Its Passmark G2D score of 1,225 is 36.7% higher than the mobile chip's 896, indicating faster 2D desktop rendering. Even in DirectX 10, a legacy API, the desktop card holds a 40.3% lead with a score of 181 versus 129. In eight of these nine benchmarks, the RTX 4070 Ti SUPER's wins are substantial, ranging from 28% to over 120%, painting a picture of overwhelming superiority in traditional rasterized and compute workloads.

However, the single win for the RTX 5070 Mobile is the most intriguing data point. In the Geekbench Vulkan test, the mobile GPU scores 116,960, which is a 54.1% lead over the desktop card's 53,683. This is a dramatic reversal of form. The Vulkan API is known for its low overhead and ability to leverage specific hardware features more directly. This result implies that the Blackwell 2.0 architecture in the RTX 5070 Mobile has a significant advantage in how it handles Vulkan's command buffers and draw calls, despite having far fewer cores and lower clock speeds. It suggests a fundamental architectural efficiency gain in the newer generation that is specifically exposed by this API, while older APIs and compute tasks remain heavily dependent on raw silicon resources.

The Verdict

The data unequivocally points to the NVIDIA GeForce RTX 4070 Ti SUPER as the superior performer in the vast majority of scenarios. Its win rate of 8 out of 9 benchmarks, with an average advantage of over 50% in its victories, demonstrates a level of performance that the RTX 5070 Mobile cannot match. The desktop card's average benchmark score of 31,087 places it in the 76th percentile of all GPUs, while the mobile chip's average of 29,928 puts it in the 75th percentile. Despite the close percentile ranking, the actual benchmark deltas show that the desktop part is significantly faster in almost every measurable way.

However, the data also tells a story of purpose. The RTX 5070 Mobile is not designed to compete with a triple-slot, 285 W desktop card. Its 50 W TDP and "IGP" slot width classify it as an integrated part for laptops. The Verdict from this data is not that one is "better" than the other, but that they serve different masters. The RTX 4070 Ti SUPER is the definitive choice for a stationary user who demands maximum performance in compute, DirectX gaming, and general graphical output. The RTX 5070 Mobile, despite losing the performance war, is the only option for high-performance gaming in a portable form factor. Its single Vulkan win hints at a forward-looking architecture that may offer unexpected efficiency in future titles that heavily utilize this API.

Where Each One Wins

The RTX 4070 Ti SUPER wins in every category except one. Its victories span the entire spectrum of legacy and modern graphics APIs (DirectX 9, 10, 11, 12), general compute (OpenCL, Passmark Compute), and 2D desktop workloads. This makes it the clear winner for users who prioritize raw performance in current and older games, as well as for professionals running GPU-accelerated applications that rely on OpenCL or CUDA-based compute. The 121.9% lead in GPU compute solidifies its position for tasks like video encoding, 3D rendering, and scientific simulation.

The RTX 5070 Mobile's only win is in the Geekbench Vulkan test. This is a specific, but potentially significant, victory. It suggests that for applications built on the Vulkan API, the newer Blackwell architecture has a distinct advantage. This could translate to better performance in modern cross-platform game engines that favor Vulkan. For a user primarily playing games that are Vulkan-based, the mobile chip might offer a more competitive experience than its other benchmark scores would suggest. This is the one area where the data indicates the mobile part's newer architecture provides a tangible benefit over the older, more powerful desktop GPU.

Architecture Differences

The two GPUs are built on different generations of NVIDIA architecture. The RTX 4070 Ti SUPER is based on the Ada Lovelace architecture, using the AD103 chip, while the RTX 5070 Mobile uses the newer Blackwell 2.0 architecture on the GB206 chip. Both are fabricated on a 5 nm process at TSMC, with nearly identical transistor densities (121.1M / mm² for the desktop and 121.0M / mm² for the mobile).

The most fundamental difference lies in the scale of the silicon. The AD103 chip is a massive 379 mm² die containing 45,900 million transistors. In contrast, the GB206 chip is less than half the size at 181 mm², housing only 21,900 million transistors. This translates to a massive difference in core counts. The desktop card has 8,448 shading units, 264 TMUs, and 96 ROPs, while the mobile chip has 4,608 shading units, 144 TMUs, and just 48 ROPs. The RTX 4070 Ti SUPER also has 66 RT cores and 264 Tensor cores, compared to the 36 RT cores and 144 Tensor cores in the RTX 5070 Mobile.

The memory subsystems also differ significantly. The RTX 4070 Ti SUPER uses 16 GB of GDDR6X on a 256-bit bus, delivering 672.3 GB/s of bandwidth. The RTX 5070 Mobile uses 8 GB of faster GDDR7 memory, but on a much narrower 128-bit bus, resulting in substantially lower bandwidth of 384.0 GB/s. This difference in memory bandwidth is a major factor in the desktop card's superior performance in most tests, particularly at higher resolutions and in memory-intensive applications.

Specification Differences

The two cards differ on nearly every core specification. The RTX 4070 Ti SUPER has a base clock of 2340 MHz and a boost clock of 2610 MHz, while the RTX 5070 Mobile operates at a significantly lower 907 MHz base and 1425 MHz boost. The desktop card's FP32 compute is rated at 44.10 TFLOPS, while the mobile chip is rated at 13.13 TFLOPS. Pixel and texture rates follow the same pattern, with the desktop card achieving 250.6 GPixel/s and 689.0 GTexel/s versus the mobile's 68.40 GPixel/s and 205.2 GTexel/s.

Power and physical specifications are where the mobile chip's purpose is clear. The RTX 4070 Ti SUPER has a TDP of 285 W, requires a 1x 16-pin power connector, and a 600 W suggested PSU. It is a triple-slot card measuring 310 mm in length. The RTX 5070 Mobile, in contrast, has a TDP of only 50 W, uses no power connectors, and is classified as an IGP. It has no dimensions listed and its display outputs are "Portable Device Dependent". The bus interface also differs, with the desktop card using PCIe 4.0 x16 and the mobile using the newer PCIe 5.0 x16. The RTX 4070 Ti SUPER was released on 2024-01-23 and is end-of-life, while the RTX 5070 Mobile was released on 2025-04-14 and is still active.
