NVIDIA GeForce RTX 5080 Mobile vs NVIDIA RTX 5880 Ada Generation Comparison

The Verdict

The database separates these two NVIDIA parts into distinct roles. The NVIDIA RTX 5880 Ada Generation is the workstation heavyweight, built for compute throughput and large memory capacity. The NVIDIA GeForce RTX 5080 Mobile is the portable gaming and general-purpose option, winning more individual benchmark tests but at a far lower power envelope. The head-to-head record is 5 wins for the RTX 5080 Mobile against 3 for the RTX 5880 Ada, but the nature of those wins is decisive: the mobile part dominates in DirectX and 2D workloads, while the desktop Ada card leads in raw compute and legacy DirectX 9.

For users who prioritize OpenCL compute or GPU compute workloads, the RTX 5880 Ada Generation is the clear choice. Its Geekbench OpenCL score of 326898 is 95.8% higher than the RTX 5080 Mobile's 166986, a massive margin that reflects its 14080 shading units and 440 tensor cores. The RTX 5880 Ada also wins Passmark GPU compute by 17.1% (14208 vs 12134). This is the card for rendering, simulation, or any task that scales across many cores.

For gamers, laptop builders, or users who need strong DirectX performance in a low-power package, the RTX 5080 Mobile is the better fit. It wins Passmark DirectX 12 by 39.7% (116 vs 70), DirectX 11 by 9.9% (253 vs 228), and DirectX 10 by 2.3% (171 vs 167). Its Passmark G3D score of 27711 is 9.4% higher than the RTX 5880 Ada's 25096. The mobile part also delivers a 29% advantage in Passmark G2D (1095 vs 777), suggesting snappier 2D and UI performance.

The RTX 5880 Ada Generation commands an 85th percentile ranking among all GPUs, while the RTX 5080 Mobile sits at the 81st percentile. Despite the mobile chip's higher win count, the average benchmark score tells a different story: the RTX 5880 Ada averages 45972 across all tests, versus 38349 for the RTX 5080 Mobile. The Ada card's average score is closest to the NVIDIA RTX A2000 (46043, a 0.2% difference), while the RTX 5080 Mobile sits near the GeForce MX570 (38299, a 0.1% difference). These averages reflect the desktop card's strength in compute-heavy tests that carry more weight.

Where Each One Wins

The RTX 5880 Ada Generation dominates in compute and memory bandwidth. Its Geekbench OpenCL result is nearly double the mobile chip's, and its Passmark GPU compute score of 14208 outpaces the RTX 5080 Mobile's 12134. The Ada card also wins Passmark DirectX 9 by 6.7% (335 vs 314), indicating strong legacy rasterization performance. With 48 GB of GDDR6 memory on a 384-bit bus delivering 864.0 GB/s, the RTX 5880 Ada is built for large datasets and multi-GPU rendering workloads. Its 176 ROPs and 440 TMUs give it a pixel rate of 433.0 GPixel/s and a texture rate of 1,082.4 GTexel/s, figures that dwarf the mobile part's 144.0 GPixel/s and 360.0 GTexel/s.

The RTX 5080 Mobile excels in modern graphics APIs and 2D tasks. It wins Passmark DirectX 12 by a wide margin, DirectX 11, DirectX 10, G3D, and G2D. Its Passmark G3D score of 27711 is the single highest test score between the two parts, and its G2D score of 1095 shows strong desktop compositing performance. The mobile chip uses GDDR7 memory with a 256-bit bus, achieving 896.0 GB/s bandwidth, slightly higher than the Ada card's 864.0 GB/s despite a smaller 16 GB capacity. Its 7680 shading units and 60 RT cores are fewer than the Ada card's, but they are paired with a 1500 MHz boost clock that suits efficiency-focused designs.

The RTX 5080 Mobile also wins on 3DMark Steel Nomad DX12 with a score of 4952, a test the RTX 5880 Ada does not appear in the recorded data. Its Geekbench Vulkan score of 169754 is notably higher than its OpenCL score, indicating strong driver optimization for modern APIs. The RTX 5880 Ada has no recorded Vulkan benchmark, so cross-API comparisons remain limited to OpenCL and Passmark suites.

Architecture Differences

The two GPUs come from different NVIDIA architectures and process nodes. The RTX 5880 Ada Generation uses the AD102 chip on TSMC's 5 nm process, with 76,300 million transistors on a 609 mm² die. Its transistor density is 125.3M per mm². The RTX 5080 Mobile uses the GB203 chip, also on TSMC 5 nm, but with 45,600 million transistors on a 378 mm² die, yielding a density of 120.6M per mm². Both parts are built on the same node, but the Ada chip is substantially larger and denser.

The RTX 5880 Ada Generation belongs to the "Workstation Ada (x000A)" generation and is the successor to Workstation Ampere, with Blackwell PRO W as its successor. The RTX 5080 Mobile belongs to the "GeForce 50 Mobile" generation, succeeding GeForce 40 Mobile. This generational difference shows in their feature sets: Ada Lovelace for the desktop card, Blackwell 2.0 for the mobile chip.

Core counts differ dramatically. The RTX 5880 Ada has 14080 shading units, 440 TMUs, 176 ROPs, 110 RT cores, and 440 tensor cores. The RTX 5080 Mobile has 7680 shading units, 240 TMUs, 96 ROPs, 60 RT cores, and 240 tensor cores. The Ada card has nearly double the shading units and over 80% more RT cores. Clock speeds tell a different story: both have a 975 MHz base clock, but the Ada card boosts to 2460 MHz while the mobile part boosts to only 1500 MHz. This lower boost clock reflects the mobile chip's 80 W TDP versus the Ada card's 285 W TDP.

Memory architecture diverges as well. The RTX 5880 Ada uses 48 GB of GDDR6 on a 384-bit bus, running at 2250 MHz (18 Gbps effective). The RTX 5080 Mobile uses 16 GB of GDDR7 on a 256-bit bus, running at 1750 MHz (28 Gbps effective). Despite the smaller bus, the mobile part achieves higher bandwidth: 896.0 GB/s versus 864.0 GB/s. The Ada card's larger capacity and wider bus favor capacity-bound workloads, while the mobile chip's faster memory favors bandwidth-sensitive tasks.

Physical and interface differences are stark. The RTX 5880 Ada is a dual-slot card with a 16-pin power connector, requiring a 600 W suggested PSU, and measures 267 mm long by 112 mm high. It uses PCIe 4.0 x16 and outputs 4x DisplayPort 1.4a. The RTX 5080 Mobile is an IGP (integrated graphics package) with no power connectors, no listed dimensions, and PCIe 5.0 x16. Its display outputs are listed as "Portable Device Dependent," reflecting its mobile nature. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.
