NVIDIA GeForce RTX 4080 Mobile vs NVIDIA GeForce RTX 5070 Ti SUPER Comparison

The NVIDIA GeForce RTX 4080 Mobile and the NVIDIA GeForce RTX 5070 Ti SUPER occupy different segments of the GPU landscape, despite both carrying NVIDIA branding. The database shows that the RTX 4080 Mobile is a high-end laptop part with a broad set of benchmark results, while the RTX 5070 Ti SUPER is a desktop graphics card with a much more limited set of recorded data. The RTX 4080 Mobile sits in the 81st percentile of all GPUs, whereas the RTX 5070 Ti SUPER sits in the 36th percentile. This difference is primarily due to the fact that the RTX 4080 Mobile has nine benchmark scores recorded, while the RTX 5070 Ti SUPER has only a single 3DMark Steel Nomad result. The average benchmark score for the RTX 4080 Mobile is 38135, while the RTX 5070 Ti SUPER averages 6270. These numbers cannot be directly compared as apples-to-apples performance metrics, but the recorded data does offer insight into each card's position.

Head-to-Head Benchmarks

The direct benchmark comparison between these two cards is limited by the available data. The RTX 4080 Mobile has results across Geekbench OpenCL, Geekbench Vulkan, and multiple Passmark tests, while the RTX 5070 Ti SUPER has only a single 3DMark Steel Nomad DX12 score of 6269.5. The head-to-head benchmark list in the database is empty, meaning there are no common tests where both cards have recorded scores. This makes a direct performance comparison impossible from the recorded measurements.

The RTX 4080 Mobile's strongest recorded results include a Geekbench OpenCL score of 159575 and a Geekbench Vulkan score of 145807. In Passmark tests, it scores 24926 in G3D, 11191 in GPU compute, 929 in G2D, 286 in DirectX 9, 244 in DirectX 11, 157 in DirectX 10, and 96 in DirectX 12. These scores position the card well within the top quartile of all GPUs, as indicated by its 81st percentile ranking. Its nearest rivals in the database include the NVIDIA GeForce MX570 with an average score of 38299 and a performance difference of -0.4 percent, the NVIDIA GeForce RTX 5080 Mobile with an average score of 38349 and a difference of -0.6 percent, the NVIDIA GeForce RTX 4070 with an average score of 37648 and a difference of 1.3 percent, and the NVIDIA Tesla P4 with an average score of 37628 and a difference of 1.3 percent. This shows the RTX 4080 Mobile is essentially tied with the RTX 5080 Mobile and MX570, while being slightly ahead of the RTX 4070 and Tesla P4.

The RTX 5070 Ti SUPER's single recorded benchmark score of 6269.5 in 3DMark Steel Nomad DX12 places it in the 36th percentile. Its nearest rivals include the NVIDIA GeForce RTX 4070 Ti SUPER AD102 with an average score of 6270 and a performance difference of 0 percent, the NVIDIA Quadro K620 with an average score of 6282 and a difference of -0.2 percent, the AMD FirePro W600 with an average score of 6223 and a difference of 0.8 percent, and the AMD Radeon R7 M350 with an average score of 6327 and a difference of -0.9 percent. These near-neighbor scores show the RTX 5070 Ti SUPER is statistically indistinguishable from the RTX 4070 Ti SUPER AD102 in this specific test, and it trades positions with much older, lower-end workstation cards.

Because the two cards share no common benchmark tests, the biggest wins each way cannot be quantified with exact numbers. The data instead shows that the RTX 4080 Mobile has a much larger body of recorded performance data, while the RTX 5070 Ti SUPER only has a single modern DirectX 12 test result. The RTX 4080 Mobile's average score of 38135 reflects a wide range of workloads, while the RTX 5070 Ti SUPER's 6270 average is derived from one test that may not represent its full capability.

Architecture Differences

The RTX 4080 Mobile uses the AD104 chip based on the Ada Lovelace architecture, manufactured on a 5 nm process at TSMC. The RTX 5070 Ti SUPER uses the GB203 chip based on the Blackwell 2.0 architecture, also manufactured on a 5 nm process at TSMC.

The Verdict

The data indicates that these are two very different products. The RTX 4080 Mobile is a mobile chip designed for laptops, with a 110 W thermal design power, integrated form factor, and no dedicated power connectors. The RTX 5070 Ti SUPER is a desktop card with a 350 W thermal design power, dual-slot cooling, and a 16-pin power connector. The RTX 5070 Ti SUPER has higher specifications across the board: more shading units, more texture units, more raster units, more ray tracing cores, more tensor cores, higher clock speeds, more memory, a wider memory bus, and more than double the memory bandwidth. Its FP32 throughput of 43.94 TFLOPS is nearly double the 24.72 TFLOPS of the RTX 4080 Mobile.

The benchmark data, however, tells a different story in terms of recorded results. The RTX 4080 Mobile has a 81st percentile ranking with an average score of 38135 across nine tests. The RTX 5070 Ti SUPER sits at the 36th percentile with an average score of 6270 from a single test. This percentile gap is misleading because the RTX 5070 Ti SUPER's score comes from 3DMark Steel Nomad DX12, a modern and demanding test, while the RTX 4080 Mobile's average includes older DirectX 9, 10, and 11 tests that produce higher raw scores. The RTX 4080 Mobile's nearest rivals include the RTX 5080 Mobile and MX570, with performance differences under one percent, indicating strong consistency in the mobile segment. The RTX 5070 Ti SUPER's nearest rival is the RTX 4070 Ti SUPER AD102 with a zero percent difference, showing the card lands exactly at that performance level in the recorded test.

For a user choosing between these two, the decision rests on form factor and workload. The RTX 4080 Mobile is for portable systems where power draw and physical size are constrained. The RTX 5070 Ti SUPER is for a desktop tower where the 350 W power draw and dual-slot footprint are acceptable. The RTX 5070 Ti SUPER offers more raw compute resources and memory capacity, which can benefit modern workloads that scale with those resources. The RTX 4080 Mobile's data shows it performs competitively within the laptop GPU space, sitting near the RTX 5080 Mobile in average score.

Where Each One Wins

The RTX 4080 Mobile wins in the portable segment. Its 110 W thermal design power allows it to fit into laptop chassis without external power connectors. Its integrated form factor means no slot width is needed. The recorded benchmark data shows it performs strongly across a wide range of tests, including Geekbench OpenCL at 159575 and Geekbench Vulkan at 145807. Its Passmark G3D score of 24926 and GPU compute score of 11191 show solid general compute capability. The 81st percentile ranking confirms it is a high-performing mobile part, sitting near the RTX 5080 Mobile with only a 0.6 percent difference in average score.

The RTX 5070 Ti SUPER wins in raw desktop performance potential. Its 43.94 TFLOPS FP32 throughput is 77.8 percent higher than the RTX 4080 Mobile's 24.72 TFLOPS. Its 896.0 GB/s memory bandwidth is more than double the RTX 4080 Mobile's 432.0 GB/s. The 16 GB memory capacity exceeds the 12 GB of the RTX 4080 Mobile. The 256-bit bus width allows for more memory channels. The higher boost clock of 2452 MHz means faster instruction execution. The PCIe 5.0 x16 interface provides double the bandwidth of the PCIe 4.0 x16 interface for data transfer to the host system. Its 3DMark Steel Nomad DX12 score of 6269.5 places it exactly at the level of the RTX 4070 Ti SUPER AD102, which is a known high-end desktop card.

For users with a desktop system and the power budget, the RTX 5070 Ti SUPER delivers more compute resources, more memory, and faster memory. For users needing GPU acceleration in a laptop, the RTX 4080 Mobile is the only one of the two that fits that form factor. The RTX 5070 Ti SUPER's dual-slot design and 350 W power draw make it unsuitable for portable systems, while the RTX 4080 Mobile's lower clock speeds and narrower memory bus limit its peak throughput in compute-heavy tasks. The data supports the RTX 5070 Ti SUPER as the stronger performer on paper, but the RTX 4080 Mobile as the more versatile in terms of physical installation.
