NVIDIA GeForce RTX 4080 Mobile vs NVIDIA TITAN V Comparison

The NVIDIA GeForce RTX 4080 Mobile and the NVIDIA TITAN V represent two very different approaches to high-end graphics. The RTX 4080 Mobile is a modern, power-efficient laptop part built on a 5 nm process, while the TITAN V is a massive, power-hungry desktop behemoth from the Volta era. Despite the TITAN V's exotic HBM2 memory and much larger die, the benchmark data shows that the mobile RTX 4080 decisively outperforms it in most modern workloads, winning 7 out of 9 head-to-head tests. The TITAN V, however, retains a narrow edge in a couple of specific legacy and API scenarios, making this a fascinating comparison of architecture versus sheer brute force.

Where Each One Wins

The RTX 4080 Mobile is the clear winner in the vast majority of gaming and compute scenarios. Its most significant victories come in DirectX 11, where it posts a score of 244 versus the TITAN V's 152, a massive 60.5% advantage. It also dominates in DirectX 9 (286 vs 213, a 34.3% lead) and DirectX 12 (96 vs 81, an 18.5% lead), showing that its Ada Lovelace architecture handles legacy and current graphics APIs far more efficiently. The gap continues in pure rasterization performance, with the RTX 4080 Mobile scoring 24926 in Passmark G3D compared to the TITAN V's 19805, a 25.9% difference. Compute workloads also favor the newer chip, as it leads in Passmark GPU Compute by 20.8% (11191 vs 9263) and in Geekbench OpenCL by 1.5% (159575 vs 157265).

The TITAN V's wins are fewer but notable for their context. It takes the Geekbench Vulkan test with a score of 152117, beating the RTX 4080 Mobile's 145807 by 4.1%. This suggests that in pure Vulkan compute or specific low-level API tasks, the TITAN V's raw hardware resources, such as its 640 tensor cores and massive memory bandwidth, can still flex their muscles. It also narrowly edges out the RTX 4080 Mobile in the Passmark G2D test, scoring 937 versus 929, a marginal 0.9% difference that points to slightly faster 2D desktop rendering performance.

The Verdict

The data is unambiguous: the NVIDIA GeForce RTX 4080 Mobile is the superior overall GPU for nearly all users. Its wins in DirectX 10, 11, and 12, combined with a 25.9% lead in the G3D test and a 20.8% lead in compute, make it the stronger choice for gaming, content creation, and general GPU-accelerated tasks. Its higher average benchmark score of 38135, compared to the TITAN V's 34355, reflects this broad superiority. The RTX 4080 Mobile also sits at the 81st percentile of all GPUs, while the TITAN V sits at the 79th, confirming its higher standing in the overall performance hierarchy.

The NVIDIA TITAN V should only be considered by users with a very specific need for Vulkan-based workloads, where its 4.1% lead in that specific test could be relevant. However, this niche advantage comes with significant caveats: it is an end-of-life product, has a much higher TDP of 250 W requiring a 600 W power supply, and is a dual-slot card with external power connectors, making it unsuitable for anything but a desktop workstation. For a laptop user, the choice is clear. For a desktop user looking at modern games and applications, the RTX 4080 Mobile, in a laptop form, delivers better performance across the board.

Head-to-Head Benchmarks

The most striking disparity is in DirectX 11 performance. The RTX 4080 Mobile achieves a score of 244, while the TITAN V manages only 152. This 60.5% delta is the largest of any test and highlights a fundamental architectural advantage for the Ada Lovelace chip in handling the draw calls and rendering paths of this API. The RTX 4080 Mobile's newer design translates to far better driver efficiency and hardware utilization in this still-common API.

The DirectX 9 test shows a similar, though less extreme, trend. The RTX 4080 Mobile scores 286, which is 34.3% higher than the TITAN V's 213. This is a significant win for older game compatibility and performance. Even in DirectX 12, the modern API, the RTX 4080 Mobile leads by 18.5%, scoring 96 versus 81. This consistent lead across all three DirectX versions suggests that the RTX 4080 Mobile is fundamentally better at processing the graphics pipeline for gaming workloads.

The gap narrows in compute-heavy tests, but the RTX 4080 Mobile still comes out on top. In Passmark GPU Compute, it scores 11191 against the TITAN V's 9263, a 20.8% lead. The Geekbench OpenCL result is much closer, with the RTX 4080 Mobile scoring 159575 versus 157265, a slim 1.5% margin. This shows that while the TITAN V's compute hardware is capable, the RTX 4080 Mobile's newer architecture and higher FP32 throughput of 24.72 TFLOPS versus 14.90 TFLOPS gives it the edge in most general compute tasks.

The TITAN V's only meaningful victory comes in Geekbench Vulkan, where it scores 152117, outperforming the RTX 4080 Mobile's 145807 by 4.1%. This is likely due to the TITAN V's massive 3072-bit memory bus and 651.3 GB/s of bandwidth, which can be leveraged more effectively in certain low-level Vulkan workloads. The other TITAN V win is a negligible 0.9% lead in Passmark G2D (937 vs 929), which is too small to have any practical impact.

Architecture Differences

The two GPUs are built on fundamentally different architectures and process nodes. The RTX 4080 Mobile uses the AD104 chip based on the Ada Lovelace architecture, manufactured on a 5 nm process at TSMC. It contains 35,800 million transistors on a 294 mm² die. In contrast, the TITAN V uses the GV100 chip based on the older Volta architecture, built on a 12 nm process, also at TSMC. The TITAN V has 21,100 million transistors spread across a massive 815 mm² die.

These architectural differences lead to distinct feature sets. The RTX 4080 Mobile supports DirectX 12 Ultimate (12_2), while the TITAN V only supports DirectX 12 (12_1). The RTX 4080 Mobile also includes 58 dedicated ray tracing cores, while the TITAN V has none. Both have tensor cores, but the RTX 4080 Mobile has 232 of them compared to the TITAN V's 640. The RTX 4080 Mobile has more shading units (7424 vs 5120) and texture mapping units (232 vs 320), but the TITAN V has more ROPs (96 vs 80). The RTX 4080 Mobile also has higher clock speeds, boosting to 1665 MHz versus the TITAN V's 1455 MHz, and a faster memory clock at 2250 MHz versus 848 MHz.

The power and form factor differences are stark. The RTX 4080 Mobile is an IGP (integrated graphics processor) with a 110 W TDP and no power connectors, designed for laptops. The TITAN V is a dual-slot desktop card with a 250 W TDP, requiring 1x 6-pin and 1x 8-pin power connectors and a 600 W power supply. It measures 267 mm in length, 112 mm in height, and 40 mm in width. The RTX 4080 Mobile uses a PCIe 4.0 x16 interface, while the TITAN V uses the older PCIe 3.0 x16. Display outputs also differ, with the TITAN V featuring 1x HDMI 2.0 and 3x DisplayPort 1.4a, while the RTX 4080 Mobile's outputs are listed as portable device dependent.
