NVIDIA GeForce RTX 5070 Ti Mobile vs NVIDIA GeForce RTX 5080 Mobile Comparison

The benchmark data is unambiguous: the NVIDIA GeForce RTX 5080 Mobile outperforms the RTX 5070 Ti Mobile in every single head-to-head test recorded, winning all nine comparisons. The RTX 5080 Mobile delivers a commanding lead across compute, graphics, and legacy API workloads, with an average benchmark score of 38349 versus 35435 for the RTX 5070 Ti Mobile. While both cards sit in the upper echelon of mobile GPUs—the RTX 5080 Mobile ranks in the 81st percentile of all GPUs and the RTX 5070 Ti Mobile in the 80th—the consistency and magnitude of the RTX 5080 Mobile's wins make it the clear performance leader in this pairing.

Head-to-Head Benchmarks

The largest single victory for the RTX 5080 Mobile comes in the Geekbench Vulkan test, where it scores 169754 against 139213 for the RTX 5070 Ti Mobile, a 21.9% advantage. This is closely followed by a 21.2% lead in Passmark DirectX 9, with scores of 314 versus 259. These two results indicate that the RTX 5080 Mobile's advantage is not confined to modern APIs; it also extends to legacy workloads, suggesting a fundamentally stronger execution core.

Compute performance tells a similar story. In Passmark GPU Compute, the RTX 5080 Mobile scores 12134, which is 20.1% higher than the RTX 5070 Ti Mobile's 10101. The Geekbench OpenCL result reinforces this, with the RTX 5080 Mobile at 166986 compared to 143870, a 16.1% delta. For users running GPGPU tasks, the RTX 5080 Mobile offers a substantial throughput advantage.

In the crucial gaming-focused benchmarks, the RTX 5080 Mobile maintains its dominance. Passmark G3D shows a score of 27711 versus 24004, a 15.4% lead. The DirectX 12 test, which is most representative of modern game engines, gives the RTX 5080 Mobile a 13.7% edge (116 vs 102). Even the older DirectX 10 and DirectX 11 tests show consistent wins of 13.2% and 6.8%, respectively. The smallest margin in the entire suite is the 6.8% lead in DirectX 11, but even that is a clear victory for the RTX 5080 Mobile. The Passmark G2D score of 1095 versus 981 (11.6% higher) indicates that the RTX 5080 Mobile also has an edge in 2D and desktop composition workloads.

Architecture Differences

Both GPUs are built on the same foundational technology: NVIDIA's Blackwell 2.0 architecture, manufactured on a 5 nm process at TSMC. They share the same API feature set, including DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, and both use GDDR7 memory. However, the silicon underneath is distinctly different. The RTX 5080 Mobile uses the GB203 chip, while the RTX 5070 Ti Mobile is based on the GB205. This is a significant differentiator, as the GB203 is a larger and more complex die.

The GB203 chip in the RTX 5080 Mobile contains 45,600 million transistors on a 378 mm² die, yielding a transistor density of 120.6M per mm². In contrast, the GB205 chip in the RTX 5070 Ti Mobile has 31,100 million transistors on a 263 mm² die, with a slightly lower density of 118.3M per mm². This means the RTX 5080 Mobile has roughly 46.6% more transistors to work with, which directly translates into a larger execution footprint.

The compute resources reflect this silicon disparity. The RTX 5080 Mobile features 7680 shading units, 240 TMUs, and 96 ROPs, compared to 5888 shading units, 184 TMUs, and 80 ROPs on the RTX 5070 Ti Mobile. The RTX 5080 Mobile also has 60 RT cores and 240 tensor cores, versus 46 RT cores and 184 tensor cores on the smaller chip. This results in raw throughput figures of 23.04 TFLOPS FP32 for the RTX 5080 Mobile, which is 35.2% higher than the 17.04 TFLOPS of the RTX 5070 Ti Mobile. The texture and pixel rates follow suit: 360.0 GTexel/s and 144.0 GPixel/s for the RTX 5080 Mobile, versus 266.2 GTexel/s and 115.8 GPixel/s for the RTX 5070 Ti Mobile.

Clock speeds are also in the RTX 5080 Mobile's favor. It runs at a base clock of 975 MHz and a boost of 1500 MHz, while the RTX 5070 Ti Mobile operates at 847 MHz base and 1447 MHz boost. Despite the higher performance, the RTX 5080 Mobile has a higher TDP of 80 W compared to 60 W for the RTX 5070 Ti Mobile, a difference that reflects the larger die and additional cores.

Where Each One Wins

The data shows a clean sweep for the RTX 5080 Mobile, so the "wins" for the RTX 5070 Ti Mobile are relative and contextual rather than based on any benchmark victory. The RTX 5080 Mobile is the unequivocal choice for any workload that prioritizes raw performance. Its 15.4% lead in Passmark G3D and 13.7% lead in DirectX 12 make it the stronger option for high-end gaming, particularly at higher resolutions or with demanding graphical settings where the additional ROPs and shading units can be fully utilized.

For compute-intensive tasks such as 3D rendering, scientific simulation, or AI inference, the RTX 5080 Mobile's 20.1% advantage in Passmark GPU Compute and 16.1% lead in Geekbench OpenCL are decisive. The larger memory subsystem also plays a role here; the RTX 5080 Mobile has 16 GB of GDDR7 on a 256-bit bus, delivering 896.0 GB/s of bandwidth, whereas the RTX 5070 Ti Mobile has 12 GB on a 192-bit bus with 672.0 GB/s. For large datasets or high-resolution textures, the RTX 5080 Mobile's extra memory capacity and bandwidth are significant practical advantages.

The RTX 5070 Ti Mobile, while losing every benchmark, is not without a rationale. Its 60 W TDP makes it a more power-efficient part, which could be preferable for thinner, lighter laptops where thermals and battery life are paramount. The 6.8% delta in DirectX 11 is its closest result, suggesting that in lighter or older game titles, the perceived performance gap might be less noticeable. For users who do not require the absolute maximum frame rates and prioritize portability, the RTX 5070 Ti Mobile still delivers a strong 24004 Passmark G3D score, placing it in the 80th percentile of all GPUs.

The Verdict

The verdict from the data is straightforward: the NVIDIA GeForce RTX 5080 Mobile is the superior GPU. It wins all nine head-to-head benchmarks, has a higher average benchmark score (38349 vs 35435), and offers a performance advantage that ranges from 6.8% to 21.9% depending on the workload. The RTX 5080 Mobile is the choice for gamers and professionals who demand maximum frame rates, faster compute times, and the ability to handle larger memory footprints. Its 81st percentile ranking, compared to the 80th for the RTX 5070 Ti Mobile, confirms its position as a top-tier mobile part.

The RTX 5070 Ti Mobile is the alternative for users who value efficiency over absolute performance. Its 60 W TDP is 25% lower than the RTX 5080 Mobile's 80 W, which can translate into a more compact laptop design and better battery life. It is still an exceptionally capable GPU, as evidenced by its 24004 Passmark G3D score and 12 GB of GDDR7 memory. However, the data does not support choosing it on the basis of performance. The RTX 5080 Mobile is faster in every measurable way, and for most users, that performance advantage will be worth the additional power draw.
