NVIDIA GeForce RTX 3080 Ti Mobile vs NVIDIA Quadro RTX 5000 Comparison

Head-to-Head Benchmarks

The recorded data shows a clean sweep for the NVIDIA GeForce RTX 3080 Ti Mobile across all nine head-to-head benchmark comparisons, though the margins vary considerably. The largest advantage appears in compute-oriented workloads. In Geekbench OpenCL, the RTX 3080 Ti Mobile scores 117,866 against the Quadro RTX 5000's 78,999, a 49.2% lead. The same 49.2% delta reappears in Passmark DirectX 12, where the mobile card posts 88 points versus 59 points for the Quadro. These two results indicate that the RTX 3080 Ti Mobile carries a substantial edge in modern, low-level API and general compute tasks.

The gap narrows somewhat in other DirectX tests. Passmark DirectX 11 shows the RTX 3080 Ti Mobile at 164 points, 17.1% ahead of the Quadro's 140 points. DirectX 10 follows a similar pattern: 131 points versus 113 points, a 15.9% delta. The smallest difference in the entire suite is Passmark DirectX 9, where the RTX 3080 Ti Mobile scores 201 and the Quadro RTX 5000 scores 195, a marginal 3.1% advantage. This suggests that for legacy DirectX 9 workloads, the two GPUs perform nearly identically, and the architectural gap is largely irrelevant under that older API.

Synthetic gaming and rasterization tests reinforce the RTX 3080 Ti Mobile's dominance. Passmark G3D gives the mobile part 19,288 points against 15,616 for the Quadro, a 23.5% lead. Passmark G2D shows a 15.4% gap, with 818 points versus 709. The Geekbench Vulkan test also favors the RTX 3080 Ti Mobile, though by a smaller margin: 107,502 versus 92,309, a 16.5% delta. Compute throughput, measured by Passmark GPU Compute, lands at 8,471 versus 6,525, a 29.8% advantage for the RTX 3080 Ti Mobile.

In terms of overall standing, the database places the RTX 3080 Ti Mobile at the 71st percentile among all GPUs, with an average benchmark score of 25,740. The Quadro RTX 5000 sits at the 67th percentile, with an average score of 21,629.

This places the two cards in different performance tiers despite both being 16 GB professional or high-end mobile parts.

The Verdict

The benchmark results are unambiguous. The NVIDIA GeForce RTX 3080 Ti Mobile wins all nine head-to-head comparisons, with no test favoring the Quadro RTX 5000. For anyone choosing strictly on measured performance, the RTX 3080 Ti Mobile is the faster card in every recorded workload, from compute (Geekbench OpenCL) to legacy DirectX 9 to modern DirectX 12 and Vulkan.

The Quadro RTX 5000, however, is a workstation card with a different set of characteristics. It has a dual-slot cooler, discrete power connectors (1x 6-pin plus 1x 8-pin), and a 550 W suggested PSU, whereas the RTX 3080 Ti Mobile is a portable device with no power connectors, indicating it is designed for laptop integration rather than desktop installation. The Quadro also offers fixed display outputs (4x DisplayPort 1.4a and 1x USB Type-C), while the RTX 3080 Ti Mobile's outputs are portable-device dependent. The Quadro RTX 5000 has a launch MSRP of 2,299 USD, a figure from its 2018 release, while the RTX 3080 Ti Mobile has no recorded launch MSRP.

For a user who prioritizes raw benchmark scores, the RTX 3080 Ti Mobile is the clear choice. For a user who requires a standalone workstation card with fixed display outputs, a dual-slot form factor, and a desktop power interface, the Quadro RTX 5000 is the only one of the two that fits that physical and connectivity profile. The data does not show any performance scenario where the Quadro wins, so the decision rests on form factor, output flexibility, and the specific needs of a stationary workstation setup.

Specification Differences

The two GPUs differ in nearly every core specification. The RTX 3080 Ti Mobile uses the GA103 chip on an 8 nm Samsung process, while the Quadro RTX 5000 uses the TU104 chip on a 12 nm TSMC process. The RTX 3080 Ti Mobile has 22,000 million transistors on a 496 mm² die, giving a transistor density of 44.4M per mm². The Quadro RTX 5000 has 13,600 million transistors on a larger 545 mm² die, with a density of 25.0M per mm².

Clock speeds differ substantially. The RTX 3080 Ti Mobile has a base clock of 810 MHz and a boost clock of 1260 MHz. The Quadro RTX 5000 runs much higher at 1620 MHz base and 1815 MHz boost. Memory clocks also differ: the RTX 3080 Ti Mobile uses 2000 MHz (16 Gbps effective), while the Quadro RTX 5000 uses 1750 MHz (14 Gbps effective).

The compute configurations are starkly different. The RTX 3080 Ti Mobile has 7,424 shading units, 232 TMUs, 96 ROPs, 58 RT cores, and 232 tensor cores. The Quadro RTX 5000 has 3,072 shading units, 192 TMUs, 64 ROPs, 48 RT cores, and 384 tensor cores. Pixel rate is close (121.0 GPixel/s versus 116.2 GPixel/s), but texture rate favors the Quadro (348.5 GTexel/s versus 292.3 GTexel/s). FP32 throughput favors the RTX 3080 Ti Mobile (18.71 TFLOPS versus 11.15 TFLOPS), while FP16 favors the Quadro (22.30 TFLOPS at 2:1 versus 18.71 TFLOPS at 1:1).

Power and physical specifications diverge. The RTX 3080 Ti Mobile has a TDP of 115 W, no power connectors, and no recorded slot width. The Quadro RTX 5000 has a TDP of 230 W, is dual-slot, uses 1x 6-pin plus 1x 8-pin connectors, and suggests a 550 W PSU. The bus interface is PCIe 4.0 x16 for the RTX 3080 Ti Mobile and PCIe 3.0 x16 for the Quadro. Display outputs are portable-device dependent for the mobile part, versus 4x DisplayPort 1.4a and 1x USB Type-C for the Quadro. Release dates also differ: the RTX 3080 Ti Mobile launched on 2022-01-24, the Quadro RTX 5000 on 2018-08-12.

Architecture Differences

The architectural gap is generational. The RTX 3080 Ti Mobile is built on the Ampere architecture, part of the GeForce 30-series and the GeForce 30 Mobile generation. The Quadro RTX 5000 uses the Turing architecture, part of the Quadro Turing (Tx000) generation. The manufacturing processes reflect this: Ampere uses 8 nm at Samsung, Turing uses 12 nm at TSMC.

The chip designs differ in scale and density. The GA103 in the RTX 3080 Ti Mobile packs 22,000 million transistors into 496 mm², a density of 44.4M per mm². The TU104 in the Quadro RTX 5000 holds 13,600 million transistors in 545 mm², a density of 25.0M per mm². This means the newer Ampere chip crams far more transistors into a smaller die, which is consistent with its higher shading unit count (7,424 versus 3,072) and larger FP32 output (18.71 TFLOPS versus 11.15 TFLOPS).

The RT core and tensor core counts also diverge. The RTX 3080 Ti Mobile has 58 RT cores and 232 tensor cores, while the Quadro RTX 5000 has 48 RT cores and 384 tensor cores. Despite having fewer tensor cores, the Quadro achieves higher FP16 throughput (22.30 TFLOPS at a 2:1 ratio) than the RTX 3080 Ti Mobile (18.71 TFLOPS at a 1:1 ratio). The Ampere part's FP16 runs at the same rate as FP32, while the Turing part doubles FP16 relative to FP32.

Memory technology is identical (GDDR6, 16 GB, 256-bit), but bandwidth favors the mobile Ampere part: 512.0 GB/s versus 448.0 GB/s. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The production status for both is end-of-life, with the Quadro RTX 5000 predating the RTX 3080 Ti Mobile by roughly three and a half years. The Quadro's predecessor is Quadro Volta and its successor is Workstation Ampere, while the RTX 3080 Ti Mobile's predecessor is GeForce 20 Mobile with no recorded successor.

Where Each One Wins

The RTX 3080 Ti Mobile wins every recorded benchmark, so the use-case split is not about performance supremacy but about workload fit and physical deployment. In compute-heavy tasks, the RTX 3080 Ti Mobile holds a 49.2% lead in Geekbench OpenCL and a 29.8% lead in Passmark GPU Compute. For modern graphics APIs, it leads by 49.2% in DirectX 12 and 16.5% in Vulkan. For rasterization, it leads by 23.5% in Passmark G3D. Any workload that values raw throughput, low-level API performance, or compute density will favor the RTX 3080 Ti Mobile.

The Quadro RTX 5000, despite losing all benchmarks, has specific advantages in physical and connectivity terms. It is a dual-slot desktop card with a fixed set of display outputs (4x DisplayPort 1.4a and 1x USB Type-C), making it suitable for a stationary workstation with multiple external monitors. It uses a standard 6-pin plus 8-pin power configuration and has a suggested PSU of 550 W, which fits typical desktop power supplies. Its PCIe 3.0 x16 interface is older but universally compatible with mainstream desktop motherboards. The RTX 3080 Ti Mobile, by contrast, has no power connectors, no slot width, and portable-device-dependent outputs, meaning it is intended for laptop integration where display routing is handled by the system.

In terms of legacy DirectX 9 workloads, the two are nearly tied, with only a 3.1% delta. This makes the Quadro RTX 5000 a viable choice for older software that does not leverage modern APIs, since the performance difference is negligible. However, for any task that uses DirectX 11, DirectX 12, Vulkan, OpenCL, or compute, the RTX 3080 Ti Mobile is measurably faster. The choice ultimately comes down to whether the user needs a self-contained workstation card with fixed outputs and desktop power (Quadro RTX 5000) or a high-performance mobile GPU that delivers superior scores across all recorded tests (RTX 3080 Ti Mobile).
