NVIDIA GeForce RTX 4090 Mobile vs NVIDIA GeForce RTX 5070 Ti Comparison

The NVIDIA GeForce RTX 5070 Ti and the NVIDIA GeForce RTX 4090 Mobile represent two fundamentally different approaches to high-performance graphics: a desktop-first Blackwell 2.0 design against a mobile Ada Lovelace part. The benchmark data shows a clear overall winner in the RTX 5070 Ti, which takes all nine head-to-head tests, but the margin varies wildly by workload. The RTX 5070 Ti posts an average benchmark score of 49957, placing it in the 86th percentile of all GPUs, while the RTX 4090 Mobile scores 43667 on average, landing in the 84th percentile. This 14.4% gap in average score is substantial, yet the RTX 4090 Mobile’s lower power envelope and integrated design make it a distinct product for a different use case.

The Verdict

The data is unambiguous: the NVIDIA GeForce RTX 5070 Ti is the superior performer in every measured benchmark, winning all nine head-to-head tests with deltas ranging from 11% to 63.6%. Its average score of 49957 places it in the 86th percentile, while the RTX 4090 Mobile sits at the 84th percentile with 43667. For a desktop user seeking maximum raw performance, the RTX 5070 Ti is the clear choice. It leads in compute-heavy tasks by a massive margin (63.6% in Passmark GPU Compute), which indicates a strong advantage for professional or rendering workflows. It also holds a 21.2% lead in Passmark G3D, a key metric for overall gaming performance.

However, the RTX 4090 Mobile is not without merit. Its 120 W TDP is less than half of the RTX 5070 Ti’s 300 W, and it uses an IGP slot width with no power connectors, making it a mobile-specific component. The RTX 5070 Ti, by contrast, is a dual-slot desktop card requiring a 700 W suggested PSU and a 16-pin connector. Therefore, the verdict is situational. Users building or upgrading a desktop system with adequate power and space should unequivocally choose the RTX 5070 Ti, as its performance lead is decisive. Users who require high-end performance in a laptop form factor have no choice but the RTX 4090 Mobile, which despite being slower, is a capable GPU in its own right, sitting just 0.8% ahead of the NVIDIA Quadro M6000 in its nearest rival rankings.

Head-to-Head Benchmarks

The RTX 5070 Ti’s dominance is consistent across all test categories, but the magnitude of its wins reveals its architectural strengths. In compute-oriented workloads, the gap is enormous. The Passmark GPU Compute test shows the RTX 5070 Ti scoring 20203 against the RTX 4090 Mobile’s 12347, a 63.6% delta. This suggests the RTX 5070 Ti’s compute pipelines are significantly more efficient. Similarly, in the Geekbench Vulkan test, the RTX 5070 Ti achieves 225122 versus 170774, a 31.8% advantage, indicating a strong lead in graphics API utilization. The Geekbench OpenCL test shows a narrower but still decisive 17.4% win (212363 vs 180831).

In DirectX-based tests, the RTX 5070 Ti maintains a solid lead. The Passmark DirectX 12 test shows a score of 127 versus 107, an 18.7% delta, while the DirectX 11 test shows 300 versus 262, a 14.5% advantage. The DirectX 9 test yields a 13.2% lead (351 vs 310), and the DirectX 10 test shows an 11% edge (192 vs 173). These results indicate that the RTX 5070 Ti scales better across both legacy and modern DirectX APIs. The most surprising result is in the Passmark G2D test, which measures 2D graphics performance; the RTX 5070 Ti scores 1332, a 35.4% lead over the RTX 4090 Mobile’s 984. This is a substantial margin for a category that is often not a differentiator between GPUs.

The overall 3D gaming performance, as measured by Passmark G3D, shows the RTX 5070 Ti scoring 32974 versus 27212, a 21.2% lead. This is the most relevant metric for gamers, and it confirms that the RTX 5070 Ti is not just a compute monster but also a superior gaming GPU. With wins in all nine head-to-head tests, the data leaves no room for doubt regarding which GPU is faster in absolute terms.

Specification Differences

The two GPUs differ significantly in their physical and power specifications. The RTX 5070 Ti has a TDP of 300 W, whereas the RTX 4090 Mobile has a TDP of 120 W. This power difference is reflected in their form factors: the RTX 5070 Ti is a dual-slot card with dimensions of 304 mm in length, 137 mm in height, and 48 mm in width, while the RTX 4090 Mobile is an IGP (Integrated Graphics Processor) with no listed dimensions. The RTX 5070 Ti requires a single 16-pin power connector and a suggested PSU of 700 W, while the RTX 4090 Mobile has no power connectors and no suggested PSU. The bus interface also differs: the RTX 5070 Ti uses PCIe 5.0 x16, while the RTX 4090 Mobile uses PCIe 4.0 x16. For display outputs, the RTX 5070 Ti offers 1x HDMI 2.1b and 3x DisplayPort 2.1b, whereas the RTX 4090 Mobile’s outputs are listed as "Portable Device Dependent." The RTX 5070 Ti was released on 2025-02-19, while the RTX 4090 Mobile was released on 2023-01-02, a gap of roughly two years. The RTX 5070 Ti also has a launch MSRP of 749 USD; the RTX 4090 Mobile has no listed launch MSRP.

Architecture Differences

The architectural divide between the two GPUs is substantial. The RTX 5070 Ti is built on the GB203 chip using the Blackwell 2.0 architecture, while the RTX 4090 Mobile uses the AD103 chip with the Ada Lovelace architecture. Both are fabricated by TSMC on a 5 nm process, with the RTX 5070 Ti having 45,600 million transistors on a 378 mm² die, and the RTX 4090 Mobile having 45,900 million transistors on a 379 mm² die. The transistor density is nearly identical at 120.6M / mm² for the RTX 5070 Ti and 121.1M / mm² for the RTX 4090 Mobile. The clock speeds differ markedly: the RTX 5070 Ti has a base clock of 2295 MHz and a boost clock of 2452 MHz, whereas the RTX 4090 Mobile has a base clock of 1335 MHz and a boost clock of 1695 MHz. This clock advantage is a primary driver of the RTX 5070 Ti’s performance lead.

Memory architecture also differs. The RTX 5070 Ti uses 16 GB of GDDR7 memory with a 256-bit bus, delivering a bandwidth of 896.0 GB/s. The RTX 4090 Mobile also has 16 GB of memory, but it is GDDR6 on a 256-bit bus, with a lower bandwidth of 576.0 GB/s. The memory clock is 1750 MHz (28 Gbps effective) for the RTX 5070 Ti versus 2250 MHz (18 Gbps effective) for the RTX 4090 Mobile. In terms of compute units, the RTX 5070 Ti has 8960 shading units, 280 TMUs, and 96 ROPs, while the RTX 4090 Mobile has 9728 shading units, 304 TMUs, and 112 ROPs. Interestingly, the RTX 4090 Mobile has more shading units, TMUs, and ROPs, yet it still loses in every benchmark. The RTX 5070 Ti counters with 70 RT cores and 280 tensor cores, versus the RTX 4090 Mobile’s 76 RT cores and 304 tensor cores. The pixel rate is 235.4 GPixel/s for the RTX 5070 Ti versus 189.8 GPixel/s for the RTX 4090 Mobile, and the texture rate is 686.6 GTexel/s versus 515.3 GTexel/s. The FP32 and FP16 compute are both 43.94 TFLOPS for the RTX 5070 Ti, compared to 32.98 TFLOPS for the RTX 4090 Mobile. The data shows that despite having fewer compute units, the RTX 5070 Ti’s higher clocks and faster memory result in superior performance across the board.
