NVIDIA GeForce RTX 5070 Ti vs NVIDIA GeForce RTX 5080 Mobile Comparison

Head-to-Head Benchmarks

The benchmark data shows a decisive overall victory for the NVIDIA GeForce RTX 5070 Ti, winning all ten recorded head-to-head tests. The most significant margin appears in the Passmark GPU compute test, where the desktop part scores 20,203 against 12,134 for the RTX 5080 Mobile, a 66.5% delta. This gap is far larger than any other difference between the two, indicating that raw compute throughput is where the desktop GPU pulls away most dramatically.

The next largest wins come in the 3DMark Steel Nomad DX12 test and the Geekbench Vulkan test. In Steel Nomad, the RTX 5070 Ti scores 6,604 versus 4,952, a 33.4% advantage. The Vulkan result is similarly lopsided at 32.6%, with scores of 225,122 and 169,754. These two tests are particularly relevant for modern gaming workloads, as both DX12 and Vulkan are the primary low-level graphics APIs used in contemporary titles. The Geekbench OpenCL test shows a 27.2% lead, with 212,363 against 166,986.

The gap narrows considerably in the Passmark suite, though the RTX 5070 Ti still wins every subtest. The G3D score shows a 19% lead, 32,974 versus 27,711. The DX11 subtest comes in at 18.6% ahead, with 300 versus 253. The 2D test shows a 21.6% advantage, 1,332 against 1,095. Smaller margins appear in DX10 (12.3%, 192 versus 171), DX9 (11.8%, 351 versus 314), and the narrowest gap of all, DX12, where the desktop part leads by just 9.5%, 127 versus 116.

The pattern here is clear: the RTX 5070 Ti holds a substantial lead in compute-intensive and modern API workloads, while the margin shrinks in legacy DirectX tests. The 66.5% compute delta suggests the desktop GPU has a fundamentally higher throughput ceiling, which is consistent with its much larger silicon budget and power envelope. For users prioritizing GPU compute tasks such as rendering, machine learning inference, or scientific workloads, this single metric is the most telling in the entire comparison.

Where Each One Wins

The RTX 5070 Ti is the clear winner in every measured category, but the degree of advantage varies by workload type. For GPU compute tasks, the desktop part is in a different class entirely. The 66.5% lead in Passmark GPU compute, combined with the 27.2% OpenCL advantage, makes it the obvious choice for any workflow that relies on general-purpose GPU processing. This includes tasks like video encoding, 3D rendering, physics simulation, and data-parallel workloads.

For modern gaming, the 33.4% lead in 3DMark Steel Nomad DX12 and the 32.6% lead in Vulkan indicate strong performance in current and upcoming titles that leverage these APIs. The RTX 5070 Ti also maintains a solid 19% edge in Passmark G3D, which aggregates overall 3D graphics performance. Gamers targeting high refresh rates at high resolutions will find the desktop GPU substantially more capable.

The RTX 5080 Mobile, while losing every test, still delivers respectable absolute numbers. Its 27,711 Passmark G3D score and 4,952 Steel Nomad result place it in the 81st percentile of all GPUs, which is far from weak. The mobile part's advantage is not in raw performance but in its form factor and power characteristics. With an 80W TDP and IGP slot width, it enables high-end gaming in laptops where a 300W dual-slot desktop card is physically impossible. The 9.5% DX12 delta is the closest margin, suggesting that in some lighter DirectX 12 titles, the mobile GPU's performance deficit is relatively modest.

The RTX 5070 Ti wins for desktop users with no power or space constraints. The RTX 5080 Mobile wins for users who need maximum performance in a portable chassis, accepting a significant but not crippling performance penalty.

Specification Differences

The two GPUs share the same GB203 chip, Blackwell 2.0 architecture, 5nm process node from TSMC, 45,600 million transistors, and a 378 mm² die size. Both use 16 GB of GDDR7 memory on a 256-bit bus with 896.0 GB/s bandwidth and 1750 MHz memory clock. The API support is identical: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

The core configuration differs substantially. The RTX 5070 Ti has 8,960 shading units, 280 TMUs, 70 RT cores, and 280 tensor cores. The RTX 5080 Mobile has 7,680 shading units, 240 TMUs, 60 RT cores, and 240 tensor cores. Both have 96 ROPs. The desktop part has 16.7% more shading units and TMUs, and 16.7% more RT and tensor cores.

Clock speeds show an even larger divergence. The RTX 5070 Ti runs at a base clock of 2295 MHz and boosts to 2452 MHz. The RTX 5080 Mobile is dramatically lower at 975 MHz base and 1500 MHz boost. This clock difference, combined with the core count gap, produces the measured performance disparity. The desktop GPU achieves a pixel rate of 235.4 GPixel/s and texture rate of 686.6 GTexel/s, while the mobile part manages 144.0 GPixel/s and 360.0 GTexel/s. FP32 and FP16 compute are both 43.94 TFLOPS for the desktop and 23.04 TFLOPS for the mobile, a 47.5% reduction.

Power and physical specifications could not be more different. The RTX 5070 Ti has a 300W TDP, requires a 700W suggested PSU, uses a single 16-pin power connector, and is a dual-slot card measuring 304 mm in length. The RTX 5080 Mobile has an 80W TDP, no power connectors, is classified as IGP, and has no listed dimensions since it is designed for portable devices. The desktop card outputs 1x HDMI 2.1b and 3x DisplayPort 2.1b, while the mobile GPU's display outputs are portable device dependent.

Architecture Differences

Both GPUs are built on the same Blackwell 2.0 architecture using the GB203 chip, fabricated on TSMC's 5nm process. The transistor count of 45,600 million and die size of 378 mm² are identical, yielding the same transistor density of 120.6 million transistors per square millimeter. This means the architectural differences come down to how the silicon is configured and powered, not the underlying design.

The RTX 5070 Ti is configured with the full complement of shader and tensor resources. Its 8,960 shading units operate at significantly higher clocks, reaching a boost of 2452 MHz. The RTX 5080 Mobile has fewer active units, 7,680 shading units, and runs at a much lower 1500 MHz boost. This combination of fewer units and lower clocks explains the 66.5% compute gap, as compute throughput scales with both core count and clock speed.

The RT core and tensor core counts follow the same proportional reduction. The desktop GPU has 70 RT cores and 280 tensor cores, while the mobile part has 60 and 240 respectively. For ray tracing workloads, the RTX 5070 Ti offers 16.7% more RT cores, plus the clock advantage, which should translate to noticeably faster ray-traced effects in supported games.

Memory architecture is identical. Both use 16 GB of GDDR7 on a 256-bit bus with 896.0 GB/s bandwidth. This parity means that memory capacity and bandwidth are not differentiators; any performance gap comes purely from compute resources and clock speeds.

The power delivery architecture is fundamentally different. The desktop GPU draws 300W through a dedicated 16-pin connector, enabling high sustained clocks. The mobile GPU operates within an 80W envelope with no external power connectors, forcing aggressive clock reduction to stay within thermal and power limits. This 220W difference in power budget is the root cause of the clock disparity and the subsequent performance gap.

The production status for both is active. The RTX 5070 Ti released on 2025-02-19 with a launch MSRP of 749 USD, while the RTX 5080 Mobile released on 2025-04-01 with no listed launch MSRP. The desktop part's predecessor is the GeForce 40 series, with a successor in GeForce 60. The mobile GPU's predecessor is the GeForce 40 Mobile, with no successor listed. Both use PCIe 5.0 x16 as their bus interface, ensuring comparable host connectivity.
