NVIDIA GeForce RTX 4070 Ti vs NVIDIA GeForce RTX 5080 Mobile Comparison

The Verdict

The benchmark database presents a clear picture: the NVIDIA GeForce RTX 4070 Ti outperforms the NVIDIA GeForce RTX 5080 Mobile across all ten recorded head-to-head tests. The desktop card wins every single comparison, with margins ranging from a tie in one DirectX 12 test to a commanding 51.6% lead in GPU compute. The RTX 4070 Ti holds an 84th percentile ranking among all GPUs, while the RTX 5080 Mobile sits at the 81st percentile. The average benchmark score for the RTX 4070 Ti is 44,795, compared to 38,349 for the mobile part.

This is a case where architectural generation does not translate into performance supremacy. The RTX 5080 Mobile, despite being from the newer Blackwell 2.0 architecture and released in 2025, trails the 2023-era Ada Lovelace desktop card in every recorded metric. The data indicates that the RTX 4070 Ti is the stronger choice for raw performance, particularly for users who prioritize compute workloads and high-resolution rendering. The RTX 5080 Mobile, with its 80 W TDP, is clearly designed for power-constrained environments, and its performance profile reflects that trade-off.

For users who need maximum throughput in gaming, 3D rendering, or compute tasks, the RTX 4070 Ti is the definitive pick from this data. For those who require a mobile solution with integrated graphics and minimal power draw, the RTX 5080 Mobile offers a compelling efficiency story, but it cannot match the desktop card's outright speed. The verdict is unambiguous: ten wins for the RTX 4070 Ti, zero for the RTX 5080 Mobile.

Architecture Differences

The architectural divide between these two GPUs is stark. The RTX 4070 Ti is built on the AD104 chip using the Ada Lovelace architecture, fabricated on a 5 nm process at TSMC. It packs 35,800 million transistors on a 294 mm² die, resulting in a transistor density of 121.8 million transistors per square millimeter. The RTX 5080 Mobile uses the GB203 chip with the Blackwell 2.0 architecture, also on a 5 nm TSMC process, but with 45,600 million transistors spread across a larger 378 mm² die. Its transistor density is slightly lower at 120.6 million per square millimeter.

Both GPUs share identical counts for shading units (7,680), texture mapping units (240), ray tracing cores (60), and tensor cores (240). The similarity ends there. The RTX 4070 Ti has 80 raster operations pipelines, while the RTX 5080 Mobile has 96. Memory configurations diverge significantly: the desktop card uses 12 GB of GDDR6X on a 192-bit bus, while the mobile part uses 16 GB of GDDR7 on a 256-bit bus.

The clock speeds tell a different story. The RTX 4070 Ti runs at a base clock of 2310 MHz and boosts to 2610 MHz. The RTX 5080 Mobile, by contrast, has a base clock of just 975 MHz and a boost of 1500 MHz. This dramatic clock difference explains much of the performance gap, despite the mobile part's newer architecture and larger memory pool.

The power envelope is where the mobile part asserts its identity. The RTX 4070 Ti draws 285 W and requires a 600 W power supply with a single 16-pin connector. The RTX 5080 Mobile operates at just 80 W with no power connectors, designed as an integrated graphics processor. The desktop card is dual-slot with dimensions of 285 mm in length, 112 mm in height, and 42 mm in width. The mobile part has no recorded dimensions, fitting into a portable device dependent form factor.

Specification Differences

The specification table reveals several key divergences between the two GPUs. The process node is identical at 5 nm with the same foundry, TSMC. However, the transistor count differs: 35,800 million for the RTX 4070 Ti versus 45,600 million for the RTX 5080 Mobile. Die size also differs, with the desktop card at 294 mm² and the mobile part at 378 mm².

Clock speeds are the most pronounced difference. The RTX 4070 Ti operates at a 2310 MHz base and 2610 MHz boost, while the RTX 5080 Mobile runs at 975 MHz base and 1500 MHz boost. Memory clocks also differ: the desktop card uses 1313 MHz with 21 Gbps effective speed, while the mobile part uses 1750 MHz with 28 Gbps effective.

Memory specifications diverge in every field. The RTX 4070 Ti has 12 GB of GDDR6X, a 192-bit bus, and 504.2 GB/s bandwidth. The RTX 5080 Mobile has 16 GB of GDDR7, a 256-bit bus, and 896.0 GB/s bandwidth. Despite the mobile part's superior memory specs, its lower clocks hamper overall performance.

The compute rates tell a complex story. The RTX 4070 Ti achieves a pixel rate of 208.8 GPixel/s and a texture rate of 626.4 GTexel/s, with FP32 and FP16 performance both at 40.09 TFLOPS. The RTX 5080 Mobile manages 144.0 GPixel/s, 360.0 GTexel/s, and 23.04 TFLOPS for both FP32 and FP16. The desktop card is faster in every throughput metric.

Power and physical specifications differ dramatically. The RTX 4070 Ti has a TDP of 285 W, dual-slot width, one 16-pin power connector, and a suggested PSU of 600 W. The RTX 5080 Mobile has an 80 W TDP, IGP slot width, no power connectors, and no suggested PSU. The bus interface also differs: PCIe 4.0 x16 for the desktop card versus PCIe 5.0 x16 for the mobile part. Display outputs are 1x HDMI 2.1 and 3x DisplayPort 1.4a for the RTX 4070 Ti, while the RTX 5080 Mobile is listed as portable device dependent.

Head-to-Head Benchmarks

The head-to-head results are one-sided, with the RTX 4070 Ti winning all ten tests. The largest margin comes in Passmark GPU Compute, where the desktop card scores 18,396 against the mobile part's 12,134, a 51.6% advantage. This test measures raw compute throughput, and the RTX 4070 Ti's higher clocks and desktop power envelope deliver a decisive win.

In Geekbench Vulkan, the RTX 4070 Ti scores 213,808 versus 169,754 for the RTX 5080 Mobile, a 26% lead. This is the second-largest margin and highlights the desktop card's strength in graphics API workloads. The Geekbench OpenCL test shows a narrower 6% gap, with scores of 176,953 and 166,986 respectively.

The Passmark suite reveals consistent wins across all DirectX versions. In DirectX 9, the RTX 4070 Ti scores 352 versus 314, a 12.1% advantage. DirectX 10 shows 187 versus 171, a 9.4% lead. DirectX 11 has 288 versus 253, a 13.8% margin. DirectX 12 is the only tie, with both GPUs scoring exactly 116.

The 3DMark Steel Nomad DX12 test shows a close contest: 5,024 for the RTX 4070 Ti versus 4,952 for the RTX 5080 Mobile, a slim 1.5% edge. This near-parity suggests the mobile part can compete in certain modern workloads, but it remains behind.

Passmark G3D shows 31,624 versus 27,711, a 14.1% win for the desktop card. Passmark G2D has 1,200 versus 1,095, a 9.6% margin. The RTX 4070 Ti's average benchmark score of 44,795 is 16.8% higher than the RTX 5080 Mobile's 38,349, confirming that the desktop card is the stronger performer across the board.

The nearest rival data adds context. The RTX 4070 Ti sits within 1.7% of the AMD Radeon Pro 5500 XT (45,384) and just 0.8% behind the RTX 5090 Mobile (45,152). The RTX 5080 Mobile, meanwhile, is nearly tied with the RTX 4080 Mobile (38,135) at a 0.6% delta, and with the NVIDIA GeForce MX570 (38,299) at 0.1%. This places the mobile part in a different performance tier entirely, closer to midrange mobile offerings than to the desktop flagship segment.
