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

The Verdict

The recorded data delivers an unambiguous verdict: the NVIDIA GeForce RTX 4080 SUPER wins all nine head-to-head benchmark comparisons against the NVIDIA GeForce RTX 5070 Ti Mobile. The desktop card leads by margins ranging from 27% to 96.2%, with the largest advantage in compute workloads. The RTX 4080 SUPER also holds a higher average benchmark score of 54209 versus 35435, and it sits in the 86th percentile among all GPUs, compared to the 80th percentile for the mobile part. For users who need maximum desktop performance, the RTX 4080 SUPER is the clear choice. The RTX 5070 Ti Mobile, with its 60 W TDP and IGP form factor, targets portable systems where the RTX 4080 SUPER's 320 W TDP and triple-slot cooler are not viable. The data shows no scenario in the recorded benchmarks where the mobile GPU takes a win.

Architecture Differences

The two GPUs come from different generations and architectures. The RTX 4080 SUPER uses the AD103 chip built on the Ada Lovelace architecture, part of the GeForce 40 generation, fabricated by TSMC on a 5 nm process. It integrates 45,900 million transistors on a 379 mm² die, giving a transistor density of 121.1M per mm². The RTX 5070 Ti Mobile uses the GB205 chip on the Blackwell 2.0 architecture, part of the GeForce 50 Mobile generation, also fabricated by TSMC on 5 nm. It packs 31,100 million transistors on a 263 mm² die, with a density of 118.3M per mm². The desktop part therefore carries more transistors on a larger die.

Compute resources differ substantially. The RTX 4080 SUPER has 10,240 shading units, 320 texture mapping units, and 112 ROPs. The RTX 5070 Ti Mobile has 5,888 shading units, 184 TMUs, and 80 ROPs. The desktop card also has 80 RT cores and 320 tensor cores, while the mobile GPU has 46 RT cores and 184 tensor cores. The FP32 throughput tells the same story: 52.22 TFLOPS for the desktop versus 17.04 TFLOPS for the mobile, with FP16 at a 1:1 ratio on both.

Memory technology and configuration also differ. The RTX 4080 SUPER uses 16 GB of GDDR6X on a 256-bit bus, with memory clocked at 1438 MHz (23 Gbps effective) for 736.3 GB/s bandwidth. The RTX 5070 Ti Mobile has 12 GB of GDDR7 on a 192-bit bus, with memory at 1750 MHz (28 Gbps effective) for 672.0 GB/s bandwidth. The desktop card has more capacity and higher bandwidth, while the mobile part uses newer GDDR7 memory.

Other architectural differences include the bus interface: PCIe 4.0 x16 on the desktop versus PCIe 5.0 x16 on the mobile. The RTX 4080 SUPER offers 1x HDMI 2.1 and 3x DisplayPort 1.4a outputs, while the mobile GPU's display outputs are listed as portable device dependent. The desktop card is triple-slot with a 1x 16-pin power connector and a suggested PSU of 700 W. The mobile GPU is IGP with no power connectors and no suggested PSU. The production status also differs: end-of-life for the RTX 4080 SUPER, active for the RTX 5070 Ti Mobile. Release dates are 2024-01-30 for the desktop and 2025-02-28 for the mobile.

Where Each One Wins

The RTX 4080 SUPER wins in every recorded benchmark category. The largest margin comes in Passmark GPU Compute, where the desktop card scores 19822 against 10101, a 96.2% advantage. This indicates a dominant lead in general-purpose compute workloads. The second-largest gap is in Geekbench Vulkan, with the RTX 4080 SUPER scoring 260075 versus 139213, an 86.8% lead. DirectX 9 also shows a strong margin at 47.1% (381 versus 259). The smallest relative win is in Passmark DirectX 11, at 27% (301 versus 237), followed closely by DirectX 10 at 27.8% (193 versus 151).

The RTX 5070 Ti Mobile has no recorded wins. Its closest relative performance comes in DirectX 10 and DirectX 11, where the margins are below 30%. Even there, the desktop card remains clearly ahead. The mobile GPU's strongest benchmark results relative to its own average are in DirectX 9 (259) and DirectX 11 (237), but these scores still trail the desktop part by substantial margins. For portable gaming or workstation use, the RTX 5070 Ti Mobile provides a functional baseline, but the data shows it cannot match the desktop card in any measured workload.

The RTX 4080 SUPER also holds a higher 3DMark Steel Nomad DX12 score of 6600, a benchmark not recorded for the mobile part. Its Geekbench OpenCL score of 219065 beats the mobile's 143870 by 52.3%. The Passmark G2D score of 1270 versus 981 (29.5% lead) shows the desktop card also wins in 2D performance. The RTX 5070 Ti Mobile's only advantage in the specification table is its lower power draw and newer memory type, but no benchmark data supports a performance win.

Head-to-Head Benchmarks

The benchmark data shows a consistent pattern of desktop dominance. In Geekbench OpenCL, the RTX 4080 SUPER scores 219065 against 143870, a 52.3% lead. This gap reflects the desktop card's higher shading unit count and FP32 throughput. The Geekbench Vulkan result widens the margin further: 260075 versus 139213, an 86.8% difference. This suggests the desktop architecture handles Vulkan workloads particularly well compared to the mobile part.

Passmark DirectX 10 and DirectX 11 results show the smallest relative gaps. DirectX 10 scores 193 versus 151, a 27.8% lead. DirectX 11 scores 301 versus 237, a 27% lead. These margins, while still decisive, indicate that the mobile GPU is relatively less disadvantaged in older DirectX API workloads. DirectX 12 shows a larger gap at 31.4% (134 versus 102), and DirectX 9 shows a 47.1% lead (381 versus 259). The desktop card's performance advantage grows as the API workload becomes more compute-intensive.

The 2D benchmark, Passmark G2D, shows a 29.5% lead for the RTX 4080 SUPER (1270 versus 981). The 3D benchmark, Passmark G3D, shows a 42.7% lead (34245 versus 24004). The compute benchmark, Passmark GPU Compute, delivers the largest margin at 96.2% (19822 versus 10101). This near-doubling of compute score highlights the massive difference in raw processing resources: 10,240 shading units versus 5,888, and 52.22 TFLOPS versus 17.04 TFLOPS.

The 3DMark Steel Nomad DX12 score of 6600 for the RTX 4080 SUPER stands alone, as no equivalent score is recorded for the mobile GPU.
