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

Head-to-Head Benchmarks

The recorded data shows a complete sweep for the NVIDIA GeForce RTX 4080 SUPER across all nine head-to-head benchmark comparisons. The RTX 5070 Mobile does not win a single test. The largest margin comes in the Passmark GPU Compute test, where the RTX 4080 SUPER scores 19,822 against the mobile part's 8,279, a 139.4% advantage. That gap reflects raw compute throughput, which favors the desktop card's far larger execution resources.

In Geekbench Vulkan, the RTX 4080 SUPER posts 260,075 versus 116,960 for the RTX 5070 Mobile, a 122.4% lead. This is the second-largest win for the desktop card. The Geekbench OpenCL test shows a smaller but still substantial 79.2% gap, with scores of 219,065 and 122,238 respectively. The DirectX 9 Passmark test shows a 78% delta, with the desktop card scoring 381 against 214.

The 3DMark Steel Nomad DX12 test is only recorded for the RTX 4080 SUPER, which scores 6,600; the mobile part has no entry in that test within the database. Among the shared tests, the closest result is in Passmark DirectX 12, where the RTX 4080 SUPER scores 134 and the RTX 5070 Mobile scores 93, a 44.1% gap. The DirectX 10 test shows a 49.6% delta (193 vs 129), and DirectX 11 shows 56.8% (301 vs 192). The 2D graphics test, Passmark G2D, shows a 41.7% gap (1,270 vs 896), the narrowest margin in the entire comparison.

The overall picture is unambiguous: the RTX 4080 SUPER delivers roughly 1.4x to 2.4x the performance of the RTX 5070 Mobile depending on the workload. Even the weakest result, the G2D test, shows a 41.7% lead. The aggregate average benchmark score for the RTX 4080 SUPER is 54,209, placing it in the 86th percentile of all GPUs in the database. The RTX 5070 Mobile averages 29,928, which puts it in the 75th percentile. That 24,281-point difference in average score is consistent with the head-to-head results.

Where Each One Wins

The RTX 4080 SUPER wins every benchmark category present in the database. Its strongest relative advantage is in compute-heavy and modern API workloads. The 139.4% lead in Passmark GPU Compute indicates that tasks such as rendering, physics simulation, and other GPGPU workloads will run far faster on the desktop card. Similarly, the 122.4% lead in Geekbench Vulkan and the 79.2% lead in Geekbench OpenCL point to strong performance in cross-platform compute and modern graphics APIs.

The RTX 5070 Mobile has no winning category in this dataset. Even in the 2D graphics test, which is typically less dependent on raw shading power, the desktop card leads by 41.7%. The DirectX 12 test, which often reflects modern game engine efficiency, shows the RTX 4080 SUPER at 134 versus 93, a 44.1% margin. Legacy API tests (DirectX 9 and DirectX 10) also favor the desktop card heavily, with 78% and 49.6% gaps respectively.

The practical interpretation is that the RTX 4080 SUPER is suited for high-resolution gaming, professional rendering, and compute workloads. The RTX 5070 Mobile, given its 50 W power envelope, is positioned for portable systems where absolute performance is secondary to power efficiency. Its 75th percentile ranking versus the 86th percentile of the desktop card indicates it still outperforms the majority of GPUs in the database, but it sits in a different performance class.

Architecture Differences

The RTX 4080 SUPER uses the AD103 chip on the Ada Lovelace architecture, built on a 5 nm process at TSMC. It packs 45,900 million transistors on a 379 mm² die, yielding a transistor density of 121.1M per mm². The RTX 5070 Mobile uses the GB206 chip on the Blackwell 2.0 architecture, also on TSMC's 5 nm node, but with 21,900 million transistors on a 181 mm² die, giving a density of 121.0M per mm². The transistor densities are nearly identical, but the desktop chip has roughly 2.1x the transistor count and 2.1x the die area.

The RTX 4080 SUPER features 10,240 shading units, 320 texture mapping units, and 112 ROPs. The RTX 5070 Mobile has 4,608 shading units, 144 TMUs, and 48 ROPs. Ray tracing cores number 80 on the desktop card versus 36 on the mobile part. Tensor cores follow the same pattern: 320 on the RTX 4080 SUPER versus 144 on the RTX 5070 Mobile. These resource counts directly explain the performance deltas in the benchmark data.

Clock speeds differ significantly due to power constraints. The RTX 4080 SUPER has a base clock of 2,295 MHz and a boost clock of 2,550 MHz. The RTX 5070 Mobile runs at a 907 MHz base and 1,425 MHz boost. The desktop card's higher clocks compound its shader and texture advantages. Pixel rate for the RTX 4080 SUPER is 285.6 GPixel/s versus 68.40 GPixel/s for the mobile part. Texture rate is 816.0 GTexel/s against 205.2 GTexel/s. FP32 compute is 52.22 TFLOPS for the desktop card and 13.13 TFLOPS for the mobile part, a roughly 4x difference.

Memory architecture also differs substantially. The RTX 4080 SUPER uses 16 GB of GDDR6X on a 256-bit bus, delivering 736.3 GB/s of bandwidth. The RTX 5070 Mobile uses 8 GB of GDDR7 on a 128-bit bus, with 384.0 GB/s of bandwidth. The memory clock on the desktop card is 1,438 MHz (23 Gbps effective), while the mobile part runs at 1,500 MHz (24 Gbps effective). The newer GDDR7 memory type on the mobile part has a higher per-pin data rate, but the narrower bus and half the capacity limit total bandwidth to about 52% of the desktop card's figure.

Power delivery reflects their different form factors. The RTX 4080 SUPER has a 320 W TDP, requires a triple-slot cooler, and uses a single 16-pin power connector with a suggested 700 W PSU. The RTX 5070 Mobile has a 50 W TDP, is listed as an IGP (integrated graphics processor), has no power connectors, and no suggested PSU. The mobile part uses PCIe 5.0 x16, while the desktop card uses PCIe 4.0 x16. Display outputs differ as well: the RTX 4080 SUPER provides 1x HDMI 2.1 and 3x DisplayPort 1.4a, while the RTX 5070 Mobile's outputs are listed as portable device dependent. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

The Verdict

The data shows the RTX 4080 SUPER as the clear performance leader in every measured category. Its 86th percentile ranking, 54,209 average score, and 9-0 head-to-head sweep leave no ambiguity. The nearest rival to the RTX 4080 SUPER in the database is the RTX 4080 at 54,247 average score, a 0.1% difference, meaning the SUPER variant effectively matches the non-SUPER model. The RTX 5070 Mobile's nearest rival is the RTX 3070 Ti at 29,945, a 0.1% gap, placing it in the same performance class as previous-generation high-end mobile parts.

Users who need maximum frame rates, high-resolution rendering, or heavy compute workloads should choose the RTX 4080 SUPER. Its 16 GB memory capacity, 736.3 GB/s bandwidth, and 52.22 TFLOPS FP32 throughput support demanding applications without compromise. The 320 W TDP and triple-slot design require a desktop chassis with adequate cooling and a 700 W PSU, but the performance return is substantial.

The RTX 5070 Mobile is appropriate for portable systems where the 50 W TDP and IGP form factor are mandatory. Its 8 GB GDDR7 memory and 13.13 TFLOPS FP32 performance still place it above 75% of all GPUs in the database, making it a capable mobile part for gaming and creative work. However, the 24,281-point average score gap and the fact that it loses every head-to-head test by at least 41.7% indicate it cannot match the desktop card in sustained performance.

The launch MSRP for the RTX 4080 SUPER is 999 USD. The RTX 5070 Mobile has no recorded launch MSRP in the database. The RTX 4080 SUPER is listed as end-of-life, released on 2024-01-30, with the GeForce 50 series as its successor. The RTX 5070 Mobile is active, released on 2025-04-14, and its predecessor is the GeForce 40 Mobile series.
