NVIDIA GeForce RTX 5070 Ti Mobile vs NVIDIA GeForce RTX 5090 Comparison

The NVIDIA GeForce RTX 5090 dominates the mobile RTX 5070 Ti across every recorded benchmark, with the desktop flagship delivering between 30% and 63% higher scores depending on the workload. The RTX 5070 Ti Mobile, while a capable entry into the Blackwell mobile lineup, trails significantly in raw throughput, compute, and even 2D graphics tests. The data shows a clear hierarchy: the RTX 5090 is a high-end desktop part, while the RTX 5070 Ti Mobile is a power-constrained laptop GPU.

Head-to-Head Benchmarks

The RTX 5090 wins all nine head-to-head comparisons, but the margin varies substantially by test type. The largest gap appears in compute-heavy workloads. In Geekbench OpenCL, the RTX 5090 scores 334,370 against the mobile part's 143,870, a 57% deficit for the RTX 5070 Ti Mobile. The Vulkan result is even more lopsided: 376,728 versus 139,213, meaning the RTX 5070 Ti Mobile trails by 63%. These two results reflect the massive difference in shading units and tensor core throughput.

PassMark GPU Compute tells a similar story. The RTX 5090 posts 26,756, while the RTX 5070 Ti Mobile manages 10,101, a 62.2% shortfall. This aligns with the FP32 and FP16 compute figures in the specification data: the RTX 5090 delivers 104.8 TFLOPS in both precisions, while the mobile chip delivers 17.04 TFLOPS. The gap is not linear with the score gap, but the compute-oriented benchmarks confirm the desktop part's overwhelming advantage in general-purpose GPU workloads.

DirectX 12 performance shows a smaller but still decisive gap. The RTX 5090 scores 185, while the RTX 5070 Ti Mobile scores 102, a 44.9% difference. DirectX 11 is closer in percentage terms: 341 versus 237, a 30.5% deficit. DirectX 10 and DirectX 9 results follow the same pattern, with the RTX 5090 ahead by 33.2% and 34.4%, respectively. These older API tests show that even when the workload is less demanding on modern hardware features, the desktop GPU's higher pixel rate and texture rate still produce a comfortable lead.

PassMark G3D, the overall gaming-oriented score, gives the RTX 5090 a 39.5% advantage: 39,650 versus 24,004. This is the closest of the major 3D benchmarks, which suggests the RTX 5070 Ti Mobile is relatively more efficient in gaming workloads than in compute tasks, but it remains firmly behind. The 2D test, PassMark G2D, shows the RTX 5090 at 1,413 versus 981, a 30.6% lead. This is the smallest percentage gap in the entire head-to-head set, indicating that the mobile part's lower clock speeds and reduced ROP count hurt less in 2D operations.

The RTX 5070 Ti Mobile's average benchmark score is 35,435, placing it in the 80th percentile of all GPUs. The RTX 5090's average is 79,842, which puts it in the 92nd percentile. The delta between the averages is roughly 2.25 times, consistent with the individual test deltas. Notably, the RTX 5070 Ti Mobile's nearest rivals in the database are the NVIDIA Quadro GV100 (35,520, 0.2% above), the AMD Radeon Pro Duo (35,860, 1.2% above), and the NVIDIA T1000 (36,289, 2.4% above). The RTX 5090 sits near the NVIDIA Tesla P100 PCIe 16 GB (79,605, 0.3% below) and the AMD Radeon RX 6850M XT (78,940, 1.1% below). This means the mobile chip competes with older workstation parts, while the desktop card trades blows with high-end Tesla accelerators and the fastest mobile Radeon of the previous generation.

Architecture Differences

Both GPUs use the Blackwell 2.0 architecture and are manufactured by TSMC on a 5 nm process, but they are fundamentally different silicon. The RTX 5070 Ti Mobile uses the GB205 chip, a 263 mm² die with 31,100 million transistors. The RTX 5090 uses the GB202 chip, a 750 mm² die with 92,200 million transistors. The transistor density is similar, 118.3M per mm² for the mobile chip versus 122.9M per mm² for the desktop chip, which confirms the process node is the same and the size difference is purely a function of how many resources are packed onto the die.

The execution resources differ enormously. The RTX 5070 Ti Mobile has 5,888 shading units, 184 texture mapping units, and 80 ROPs. The RTX 5090 has 21,760 shading units, 680 TMUs, and 176 ROPs. That is roughly 3.7 times more shading units and TMUs, and 2.2 times more ROPs. Ray tracing hardware follows the same pattern: 46 RT cores on the mobile part versus 170 on the desktop part. Tensor cores scale similarly, 184 versus 680.

The clock speeds do not compensate for the resource gap. The RTX 5070 Ti Mobile has a base clock of 847 MHz and a boost clock of 1,447 MHz. The RTX 5090 runs at a base of 2,017 MHz and boosts to 2,407 MHz. The desktop part has both more cores and a higher clock, which explains why the pixel rate is 423.6 GPixel/s versus 115.8 GPixel/s, and the texture rate is 1,636.8 GTexel/s versus 266.2 GTexel/s. The FP32 throughput of 104.8 TFLOPS versus 17.04 TFLOPS is the direct consequence of these combined differences.

Memory configuration is another major divider. The RTX 5070 Ti Mobile uses 12 GB of GDDR7 on a 192-bit bus, yielding 672.0 GB/s of bandwidth. The RTX 5090 uses 32 GB of GDDR7 on a 512-bit bus, yielding 1.79 TB/s. Both run the same memory clock of 1,750 MHz (28 Gbps effective), so the bandwidth advantage comes entirely from the wider bus and larger capacity. The RTX 5090's memory subsystem is not just larger, it is more than 2.6 times faster in raw bandwidth.

Power and physical design separate these parts completely. The RTX 5070 Ti Mobile has a TDP of 60 W, uses no power connectors, and is listed as an IGP form factor, meaning it is designed to be soldered and run within a laptop's thermal envelope. The RTX 5090 has a TDP of 575 W, requires a 1x 16-pin power connector, and a suggested PSU of 950 W. It is a dual-slot card measuring 304 mm in length, 137 mm in height, and 40 mm in width. The mobile part has no listed dimensions because it is portable device dependent, while the desktop card has fixed physical specifications.

The release dates also differ. The RTX 5090 launched on January 29, 2025, with a launch MSRP of 1,999 USD. The RTX 5070 Ti Mobile launched on February 28, 2025, and has no launch MSRP in the database. The RTX 5090's predecessor is the GeForce 40 series, and its successor is listed as GeForce 60. The RTX 5070 Ti Mobile's predecessor is the GeForce 40 Mobile, with no successor listed. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, and both use a PCIe 5.0 x16 interface.

The Verdict

The benchmark data indicates that the NVIDIA GeForce RTX 5090 is the superior GPU in every measured category. It wins all nine head-to-head tests, with the smallest advantage being 30.5% in DirectX 11 and the largest being 63% in Geekbench Vulkan. The average benchmark score is 79,842 versus 35,435, and the percentile ranking is 92 versus 80. For any workload that prioritizes raw performance, the RTX 5090 is the clear choice.

The RTX 5070 Ti Mobile is not without merit, but its strengths lie in efficiency and form factor, not performance. Its 60 W TDP and IGP design make it suitable for thin laptops, whereas the RTX 5090 requires a 575 W power budget, a 950 W PSU, and a dual-slot chassis. The mobile part also has a much lower transistor count and die size, which translates to lower production costs, although the database does not record pricing for the mobile chip.

Users who need maximum frame rates, compute throughput, or memory bandwidth should select the RTX 5090. Users who require a GPU that fits into a portable device and operates within a 60 W power envelope should select the RTX 5070 Ti Mobile, accepting the significant performance trade-off. The data does not support any other conclusion.

The RTX 5090's 104.8 TFLOPS of FP32 and FP16 compute, combined with 1.79 TB/s of memory bandwidth, makes it the appropriate choice for high-resolution gaming, 3D rendering, machine learning inference, and any compute-heavy task that can use 32 GB of VRAM. Its 170 RT cores also position it strongly for ray-traced workloads.

The RTX 5070 Ti Mobile wins in scenarios where the desktop GPU cannot physically be used. Its 60 W TDP and IGP form factor mean it can be integrated into a laptop, providing Blackwell architecture features like DirectX 12 Ultimate and Vulkan 1.4 support in a portable device. Its 12 GB of GDDR7 memory is still substantial for a mobile part, and its 672.0 GB/s bandwidth is respectable for a 192-bit bus. The mobile chip also has a higher transistor density per mm² than the desktop part, 118.3M versus 122.9M, though the desktop part has more total transistors.

For gaming specifically, the PassMark G3D result shows the RTX 5090 at 39,650 versus 24,004, a 39.5% lead. This is the closest major 3D benchmark, meaning the mobile part is less disadvantaged in gaming than in compute. The RTX 5070 Ti Mobile's PassMark DirectX 12 score of 102 versus 185 for the RTX 5090 confirms that modern API gaming is still heavily in the desktop card's favor, but the smaller gap in G3D suggests the mobile part is optimized for real-time graphics workloads.
