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

Head-to-Head Benchmarks

The recorded data shows a decisive sweep. The NVIDIA GeForce RTX 5090 D wins all nine head-to-head benchmark comparisons against the NVIDIA GeForce RTX 5070 Ti Mobile. No single test in the database favors the mobile part. The margin of victory varies significantly by workload, from a narrow 34% lead in 2D graphics to a dominant 64.4% lead in GPU compute.

In Geekbench OpenCL, the RTX 5090 D scores 310,674 against 143,870 for the RTX 5070 Ti Mobile, a delta of 53.7%. The Vulkan result is even wider: 376,915 versus 139,213, a 63.1% gap. These two API-level tests indicate that the desktop card roughly doubles the mobile card's raw compute throughput in general-purpose and graphics workloads.

The Passmark suite tells a similar story across different DirectX versions. In DirectX 9, the scores are 434 versus 259, a 40.3% difference. DirectX 10 shows 231 against 151, a 34.6% gap. DirectX 11 results are 371 versus 237, a 36.1% difference. The DirectX 12 test produces 219 versus 102, a 53.4% margin. These results show that the performance ratio holds relatively consistent across legacy and modern graphics APIs, with the newer API tests showing larger absolute deltas.

The Passmark G3D score, which aggregates overall 3D rendering performance, gives the RTX 5090 D a 44,065 result against 24,004 for the RTX 5070 Ti Mobile, a 45.5% lead. The 2D test is the closest comparison: 1,487 versus 981, a 34% gap. The compute test is the most lopsided: 28,396 versus 10,101, a 64.4% difference. This pattern suggests the desktop card's advantage expands with more parallel, compute-heavy workloads.

The RTX 5090 D also reaches a 92nd percentile ranking among all GPUs in the database, while the RTX 5070 Ti Mobile sits at the 80th percentile. The average benchmark score for the desktop card is 77,712, more than double the mobile card's average of 35,435.

Where Each One Wins

The RTX 5090 D wins every category in the head-to-head data, but the strength of its advantage varies by use case. In compute and Vulkan workloads, the desktop card leads by over 60%, making it the clear choice for GPU-accelerated computing, machine learning inference, and API-level performance where Vulkan is the primary interface. The OpenCL and DirectX 12 results both show roughly 53% margins, indicating strong but slightly smaller advantages in general compute and modern game APIs.

For legacy DirectX titles, the RTX 5090 D still leads but by a smaller margin. DirectX 9, 10, and 11 show deltas between 34.6% and 40.3%. This means that in older games or applications built on earlier API versions, the RTX 5070 Ti Mobile is comparatively closer to the desktop part, though it still trails. The 2D graphics test shows the smallest gap at 34%, suggesting that desktop compositing and basic 2D rendering tasks are the most forgiving for the mobile GPU.

The RTX 507 Ti Mobile has no wins to point to in this comparison. Its best relative performance appears in the DirectX 10 and 2D tests, where the delta is lowest. In absolute terms, the mobile card's Passmark G3D score of 24,004 places it in a competitive position against its own nearest rivals: the NVIDIA Quadro GV100 scores 35,520 (0.2% higher), the AMD Radeon Pro Duo scores 35,860 (1.2% higher), and the NVIDIA A2 scores 34,690 (2.1% lower). The mobile card trails those workstation parts by only a few percent, but the RTX 5090 D is in a different performance tier entirely.

Architecture Differences

Both GPUs share the same Blackwell 2.0 architecture and are built on a 5 nm process at TSMC. The foundational design is identical, but the physical implementation diverges sharply. The RTX 5090 D uses the GB202 chip with 92,200 million transistors on a 750 mm² die, while the RTX 5070 Ti Mobile uses the GB205 chip with 31,100 million transistors on a 263 mm² die. The transistor density is slightly higher on the larger chip: 122.9M per mm² versus 118.3M per mm².

The execution resources scale accordingly. The RTX 5090 D has 21,760 shading units, 680 texture mapping units, and 176 raster operations pipelines. The RTX 5070 Ti Mobile has 5,888 shading units, 184 TMUs, and 80 ROPs. The desktop card also carries 170 RT cores and 680 tensor cores, against 46 RT cores and 184 tensor cores on the mobile part. These are roughly 3.7 times more shading units and TMUs, and 2.2 times more ROPs.

Clock speeds follow the power envelope. The RTX 5090 D runs at a 2017 MHz base and 2407 MHz boost. The RTX 5070 Ti Mobile runs at 847 MHz base and 1447 MHz boost. The desktop card's boost clock is 960 MHz higher. The memory subsystem also differs substantially. The RTX 5090 D uses 32 GB of GDDR7 on a 512 bit bus, delivering 1.79 TB/s of bandwidth. The RTX 5070 Ti Mobile has 12 GB of GDDR7 on a 192 bit bus, with 672.0 GB/s. Both run the same memory clock of 1750 MHz, but the wider bus gives the desktop card a massive bandwidth advantage.

The power figures reflect the performance gap. The RTX 5090 D has a 575 W TDP, requires a 16-pin power connector, and is a dual-slot card measuring 304 mm long, 137 mm high, and 48 mm wide. The RTX 5070 Ti Mobile has a 60 W TDP, uses no power connectors, and is listed as an IGP-class form factor. The suggested PSU for the desktop card is 950 W. The mobile card has no suggested PSU because it is integrated into a portable device.

The RTX 5090 D also differs in display outputs: it provides 1x HDMI 2.1b and 3x DisplayPort 2.1b. The mobile card's outputs are listed as portable device dependent. Both cards share the same API support: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The bus interface is PCIe 5.0 x16 for both.

The Verdict

The data supports a straightforward selection. The NVIDIA GeForce RTX 5090 D is the superior part in every measured benchmark. Its average score is more than double that of the RTX 5070 Ti Mobile. The desktop card wins by margins ranging from 34% to 64.4% across nine tests. For any workload where raw GPU throughput matters, the RTX 5090 D is the only choice from this pair.

The RTX 5070 Ti Mobile remains relevant only in the context of its form factor. It is a 60 W IGP-class solution with no external power connectors, designed for portable devices. Its 80th percentile ranking and average score of 35,435 place it among capable mobile GPUs, but the desktop card sits at the 92nd percentile with an average of 77,712. The mobile part's nearest rivals, including the NVIDIA Quadro GV100 and AMD Radeon Pro Duo, score within a few percent of it, confirming that it competes with workstation-class mobile and small form factor parts rather than flagship desktop GPUs.

The 12 GB memory capacity and 672.0 GB/s bandwidth of the mobile card are adequate for its class, but the RTX 5090 D offers 32 GB and 1.79 TB/s. The 170 RT cores and 680 tensor cores on the desktop part provide substantially more ray tracing and AI acceleration capacity. The mobile part's 46 RT cores and 184 tensor cores are a fraction of that. For users who need maximum performance in a desktop chassis, the RTX 5090 D is the unambiguous pick. For users who need a GPU inside a laptop, the RTX 5070 Ti Mobile is the only viable option in this comparison, and its performance is competitive with its own nearest rivals.

The launch MSRP of the RTX 5090 D is 2,299 USD. The RTX 5070 Ti Mobile has no recorded launch MSRP.
