Head-to-Head Benchmarks

The most decisive victory for the RTX 2080 Ti comes in the passmark_gpu_compute test, where it scores 10056 against the RTX 5070 Mobile's 8279, a 17.7% margin. This is followed by its 12% lead in geekbench_vulkan (132930 vs 116960) and a 15.7% advantage in passmark_directx_10 (153 vs 129). The desktop card also wins in geekbench_opencl (128171 vs 122238, a 4.6% lead), passmark_directx_9 (235 vs 214, an 8.9% lead), passmark_g2d (927 vs 896, a 3.3% lead), and passmark_g3d (21548 vs 20355, a 5.5% lead). These results paint a picture of consistent superiority across a wide range of workloads, with the RTX 2080 Ti leveraging its higher pixel rate (136.0 GPixel/s), texture rate (420.2 GTexel/s), and 616.0 GB/s of bandwidth to outmuscle the mobile chip.

The RTX 5070 Mobile's wins are fewer but more significant for future-proofing. In passmark_directx_12, it scores 93 versus the RTX 2080 Ti's 84, a 10.7% advantage that highlights the newer architecture's superior handling of modern rendering pipelines. It also edges out the desktop card in passmark_directx_11, 192 to 190, a slim 1.1% win. Despite these two victories, the RTX 5070 Mobile's overall average score of 29928 is only 0.5% higher than the RTX 2080 Ti's 29783, confirming that its wins are concentrated in specific API tests while the desktop card wins the broader benchmark suite.

Specification Differences

The RTX 5070 Mobile and RTX 2080 Ti differ fundamentally in their physical and memory configurations. The RTX 5070 Mobile is an IGP (integrated graphics processor) with a 50 W TDP, no power connectors, and a PCIe 5.0 x16 interface. The RTX 2080 Ti is a dual-slot desktop card with a 250 W TDP, 2x 8-pin power connectors, a suggested PSU of 600 W, and a PCIe 3.0 x16 interface. Memory configurations also diverge sharply: the RTX 5070 Mobile has 8 GB of GDDR7 on a 128-bit bus with 384.0 GB/s bandwidth, while the RTX 2080 Ti has 11 GB of GDDR6 on a 352-bit bus with 616.0 GB/s bandwidth.

The RTX 5070 Mobile uses the GB206 chip based on Blackwell 2.0 architecture, built on a 5 nm process at TSMC with 21,900 million transistors on a 181 mm² die. The RTX 2080 Ti uses the TU102 chip based on the older Turing architecture, built on a 12 nm process at TSMC with 18,600 million transistors on a 754 mm² die. This results in a transistor density of 121.0M / mm² for the RTX 5070 Mobile versus 24.7M / mm² for the RTX 2080 Ti. In terms of rendering capabilities, the RTX 5070 Mobile has 36 RT cores and 144 tensor cores, while the RTX 2080 Ti has 68 RT cores and 544 tensor cores. The RTX 5070 Mobile's FP16 performance is 13.13 TFLOPS (1:1 ratio with FP32), whereas the RTX 2080 Ti's FP16 is 26.90 TFLOPS (2:1 ratio). The RTX 5070 Mobile has a higher FP32 throughput at 13.13 TFLOPS compared to the RTX 2080 Ti's 13.45 TFLOPS. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The RTX 5070 Mobile is from the GeForce 50 Mobile generation released on 2025-04-14, while the RTX 2080 Ti is from the GeForce 20 generation released on 2018-09-19 and is now end-of-life.

Where Each One Wins

The RTX 2080 Ti is the decisive winner in legacy and compute-heavy scenarios. Its 17.7% lead in passmark_gpu_compute makes it the clear choice for users running GPGPU workloads, machine learning inference, or any task that leverages raw compute throughput. Its 12% advantage in Vulkan and 15.7% lead in DirectX 10 also make it superior for older games and applications built on those APIs. The 5.5% win in passmark_g3d and 8.9% in DirectX 9 further cement its status as the better performer for a broad library of existing titles. With 11 GB of memory and 616.0 GB/s bandwidth, the RTX 2080 Ti is also better suited for high-resolution textures and data-intensive scenarios. The RTX 5070 Mobile wins where modern API efficiency matters. Its 10.7% advantage in DirectX 12 indicates that it is better optimized for current and upcoming game engines that rely on this API's advanced features. Its 1.1% win in DirectX 11 also shows it handles that older API competitively. For users building a system around the latest DirectX 12 titles, the RTX 5070 Mobile's architecture provides a performance edge despite its smaller memory footprint and lower power envelope. The RTX 5070 Mobile's 50 W TDP and IGP form factor also make it the only viable option for thin-and-light laptops, where the RTX 2080 Ti's 250 W TDP and dual-slot design are physically impossible.
