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

The Verdict

The data here draws a clear line: the NVIDIA GeForce RTX 5070 Ti is the stronger performer in 9 of 10 head-to-head benchmarks, with an average benchmark score of 49957 against the RTX 5090 Mobile's 45152. That is a 10.7% overall advantage. The desktop card also sits at the 86th percentile among all GPUs, two points above the mobile part's 84th percentile. If you are building a desktop rig and want the rawest frame rates, the RTX 5070 Ti is the pick. The RTX 5090 Mobile exists for a different purpose: it delivers 24 GB of GDDR7 memory and a 95 W TDP in an IGP form factor, meaning it belongs in a laptop where power limits and portability trump raw throughput. The mobile part wins exactly one benchmark—PassMark DirectX 12—and loses the rest, so its appeal is not about winning; it is about fitting into a thin chassis while still carrying the Blackwell 2.0 feature set. Choose the RTX 5070 Ti for performance, the RTX 5090 Mobile for a mobile form factor with more memory.

Architecture Differences

Both GPUs share the same fundamental silicon: the GB203 chip, Blackwell 2.0 architecture, TSMC 5 nm process, 45,600 million transistors, and a 378 mm² die size. The transistor density is identical at 120.6M / mm². That is where the similarity ends. The RTX 5070 Ti runs desktop clocks with a 2295 MHz base and 2452 MHz boost, while the RTX 5090 Mobile drops to a 990 MHz base and 1515 MHz boost. That clock gap is the single largest architectural differentiator, and it explains most of the performance spread. The mobile part compensates with more execution hardware: 10496 shading units versus 8960, 328 TMUs versus 280, 112 ROPs versus 96, 82 RT cores versus 70, and 328 tensor cores versus 280. Yet the desktop part still wins because its clocks are roughly 62% higher on boost. The memory subsystem is identical in type and bus—GDDR7 on a 256-bit bus at 896.0 GB/s—but the capacities differ: 16 GB on the desktop, 24 GB on the mobile. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The RTX 5070 Ti also has a dual-slot cooler with a 1x 16-pin power connector and a 700 W suggested PSU, while the RTX 5090 Mobile is an IGP with no power connector and no suggested PSU, relying on the laptop's own power delivery.

Head-to-Head Benchmarks

The RTX 5070 Ti wins the most important modern test, 3DMark Steel Nomad DX12, with a score of 6604 against 5871, a 12.5% lead. That is a solid margin for a desktop card against a mobile part. In Geekbench Vulkan, the gap widens to 13.5% (225122 vs 198405), and in OpenCL it is 5.2% (212363 vs 201834). The PassMark suite tells a similar story: DirectX 11 shows an 11.5% lead (300 vs 269), DirectX 9 shows 8.3% (351 vs 324), and DirectX 10 shows 4.9% (192 vs 183). The 3DMark result and the Geekbench Vulkan score are the two largest wins for the desktop card, and both are modern API tests that matter for current games.

The single win for the RTX 5090 Mobile is PassMark DirectX 12, where it scores 138 against 127, a -8% delta in favor of the mobile part. That is a narrow 8.7% advantage, and it is the only test where the mobile card comes out ahead. It is a curious outlier given the desktop card's 12.5% win in 3DMark Steel Nomad (also DX12), but benchmark methodology varies; the data is what it is. The compute gap is the most dramatic: PassMark GPU Compute shows the RTX 5070 Ti at 20203 versus 13401, a 50.8% lead. That is the single biggest delta in the entire comparison. The 2D test also favors the desktop card heavily: PassMark G2D at 1332 vs 1057, a 26% lead. In PassMark G3D, the desktop wins 32974 vs 30034, a 9.8% margin. Across all ten tests, the RTX 5070 Ti wins nine, with an average delta of roughly 15% when you include the compute outlier.

Specification Differences

The two cards differ on nearly every spec that matters. The RTX 5070 Ti has a base clock of 2295 MHz and boost of 2452 MHz; the RTX 5090 Mobile has a base of 990 MHz and boost of 1515 MHz.

The desktop has a launch MSRP of 749 USD; the mobile has no launch MSRP.

FAQ

Q: Which card has higher raw compute performance?

A: The RTX 5070 Ti, with 43.94 TFLOPS FP32 and FP16, versus 31.80 TFLOPS on the RTX 5090 Mobile.

A: Yes, in PassMark DirectX 12, it scores 138 vs 127, a -8% delta in favor of the mobile part.

Q: Why does the RTX 5090 Mobile have more shading units but lower performance?

A: The mobile part has 10496 shading units versus 8960, but its boost clock is only 1515 MHz versus 2452 MHz on the desktop, so the desktop's higher clocks overcome the mobile's extra hardware.

Q: Which card has more memory, and does it matter for the benchmarks?

A: The RTX 5090 Mobile has 24 GB versus 16 GB, but in the benchmark results the desktop card still wins 9 of 10 tests, so the extra memory does not translate to a performance win in these tests.

A: Yes, both use the GB203 chip with Blackwell 2.0 architecture on TSMC's 5 nm process with 45,600 million transistors.

Where Each One Wins

The RTX 5070 Ti is the clear winner for desktop gaming and compute-heavy workloads. Its 50.8% lead in PassMark GPU Compute makes it the obvious choice for any task that stresses raw parallel throughput, such as rendering, simulation, or AI inference. The 12.5% win in 3DMark Steel Nomad DX12 indicates it is also the better card for modern AAA games that use DX12 and ray tracing. The 13.5% Vulkan lead reinforces that for Linux gaming or Vulkan-native titles, the desktop card is the stronger option. The 26% lead in PassMark G2D is a bonus for desktop productivity, though that test is less relevant to gaming. The RTX 5070 Ti also has the advantage of a full-size dual-slot cooler and a 1x 16-pin power connector, which means it can sustain its clocks under load without thermal throttling. If you have the physical space and the power budget, there is no reason to pick the mobile part for a desktop build.

The RTX 5090 Mobile wins in exactly one benchmark: PassMark DirectX 12. If your workload specifically relies on that test's rendering path, the mobile card edges ahead, but the margin is small. The mobile card also has 24 GB of memory, which is 50% more than the desktop's 16 GB. That matters for large datasets or texture-heavy workloads that exceed 16 GB, though the benchmark suite does not reflect that advantage. The 95 W TDP and IGP form factor make it the only viable choice for a thin-and-light laptop. It draws less than a third of the desktop card's power, and it requires no external power connector. The RTX 5090 Mobile also has more RT cores (82 vs 70) and tensor cores (328 vs 280), so in theory it could handle ray tracing and tensor workloads more efficiently per clock, but the benchmark results show the desktop card's clock advantage overrides that. For a portable system that must fit in a laptop chassis, the RTX 5090 Mobile is the only option between these two. For everything else, the RTX 5070 Ti is the one to buy.
