A: Yes, both use Blackwell 2.0 architecture and are fabricated on a 5 nm process at TSMC. They also share the same API support: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Architecture Differences

The two GPUs share the same Blackwell 2.0 architecture and TSMC 5 nm process, but the silicon underneath is very different. The RTX 5070 Mobile uses the GB206 chip, which measures 181 mm² and contains 21,900 million transistors. The RTX 5070 Ti uses the larger GB203 chip, measuring 378 mm² with 45,600 million transistors. Transistor density is nearly identical: 121.0M / mm² for the mobile part and 120.6M / mm² for the Ti.

The shading engine scales accordingly. The RTX 5070 Mobile has 4,608 shading units, 144 texture mapping units, 48 ROPs, 36 ray tracing cores, and 144 tensor cores. The RTX 5070 Ti doubles down with 8,960 shading units, 280 TMUs, 96 ROPs, 70 RT cores, and 280 tensor cores. These are not just larger numbers; they structurally change what each chip can do per clock.

Clock behavior also differs significantly. The RTX 5070 Mobile runs a base clock of 907 MHz and a boost clock of 1,425 MHz. The RTX 5070 Ti runs a base clock of 2,295 MHz and a boost clock of 2,452 MHz. The higher clocks, combined with the larger core count, give the Ti a massive throughput advantage. Pixel rate for the mobile part is 68.40 GPixel/s versus 235.4 GPixel/s for the Ti. Texture rate is 205.2 GTexel/s versus 686.6 GTexel/s. FP32 compute is 13.13 TFLOPS versus 43.94 TFLOPS, with FP16 running at a 1:1 ratio on both.

Memory architecture is another major split. The RTX 5070 Mobile has 8 GB of GDDR7 on a 128-bit bus, running at 1500 MHz with 24 Gbps effective speed, yielding 384.0 GB/s. The RTX 5070 Ti has 16 GB of GDDR7 on a 256-bit bus, running at 1750 MHz with 28 Gbps effective speed, yielding 896.0 GB/s. That is 2.33 times the bandwidth and double the capacity.

Power delivery is the most obvious physical difference. The RTX 5070 Mobile is rated at 50 W TDP, is an IGP (integrated into the motherboard), and requires no power connectors. The RTX 5070 Ti is rated at 300 W TDP, is a dual-slot card, requires a single 16-pin power connector, and carries a suggested PSU of 700 W. The Ti also has a full set of display outputs (1x HDMI 2.1b and 3x DisplayPort 2.1b), while the mobile part’s outputs are listed as portable device dependent.

The Verdict

The data is unambiguous. The RTX 5070 Ti is the stronger GPU in every recorded metric, and the margin is substantial. It wins all nine head-to-head benchmarks, with deltas ranging from 26.8% to 59%. The average benchmark score is 49,957 versus 29,928, a difference of 67 percent. Anyone needing maximum frame rates, high-resolution rendering, or compute throughput should select the RTX 5070 Ti.

The RTX 5070 Mobile serves a different purpose entirely. Its 50 W TDP and IGP form factor mean it fits into thin, portable systems where there is no room for a dual-slot card or a 16-pin power connector. It delivers 75th percentile performance, which places it near desktop GPUs like the RTX 3070 Ti and RTX 2080 Ti. For a mobile part running at 50 W, that is a strong result, but it is not a substitute for the RTX 5070 Ti’s 86th percentile standing.

There is no scenario in the recorded data where the RTX 5070 Mobile outperforms the RTX 5070 Ti. The choice is purely about physical constraints. If the system must be a thin laptop with no external power connector, the RTX 5070 Mobile is the only option. If the system can accommodate a 300 W dual-slot card with a 16-pin connector and a 700 W PSU, the RTX 5070 Ti is the clear pick.

Specification Differences

The two cards differ on nearly every specification that affects performance. The chip is GB206 for the mobile part and GB203 for the Ti. The mobile part uses 21,900 million transistors on a 181 mm² die; the Ti uses 45,600 million on a 378 mm² die. Transistor density is effectively the same, at 121.0M / mm² versus 120.6M / mm².

Clock speeds are much higher on the Ti. Base clock is 907 MHz versus 2,295 MHz. Boost clock is 1,425 MHz versus 2,452 MHz. Memory clock is 1500 MHz (24 Gbps effective) versus 1750 MHz (28 Gbps effective). Memory size is 8 GB versus 16 GB. Memory bus width is 128 bit versus 256 bit. Memory bandwidth is 384.0 GB/s versus 896.0 GB/s.

Core counts scale up across the board. Shading units: 4,608 versus 8,960. TMUs: 144 versus 280. ROPs: 48 versus 96. RT cores: 36 versus 70. Tensor cores: 144 versus 280. Pixel rate: 68.40 GPixel/s versus 235.4 GPixel/s. Texture rate: 205.2 GTexel/s versus 686.6 GTexel/s. FP32: 13.13 TFLOPS versus 43.94 TFLOPS. FP16 runs at the same ratio on both.

Power and physical specifications are completely different. The mobile part is 50 W TDP, IGP slot width, and has no power connectors. The Ti is 300 W TDP, dual-slot, with a 1x 16-pin connector and a suggested PSU of 700 W. The Ti measures 304 mm in length, 137 mm in height, and 48 mm in width. The mobile part has no listed dimensions. Display outputs are portable device dependent on the mobile part, while the Ti has 1x HDMI 2.1b and 3x DisplayPort 2.1b. The Ti has a launch MSRP of 749 USD; the mobile part has no listed MSRP.

Head-to-Head Benchmarks

The RTX 5070 Ti wins every comparison in the head-to-head set, but the margins vary by workload. The smallest gap is in Passmark DirectX 12, where the Ti scores 127 versus 93, a delta of 26.8%. The largest gap is in Passmark GPU Compute, where the Ti scores 20,203 versus 8,279, a delta of 59%. This suggests the Ti’s advantage grows with compute-heavy workloads, not just raw rasterization.

In Geekbench OpenCL, the Ti scores 212,363 versus 122,238, a delta of 42.4%. In Geekbench Vulkan, the Ti scores 225,122 versus 116,960, a delta of 48%. The Vulkan gap is notably larger than the OpenCL gap, indicating the Ti scales better with low-level API overhead.

Legacy DirectX tests show consistent but smaller gaps. Passmark DirectX 10: 192 versus 129, a delta of 32.8%. Passmark DirectX 11: 300 versus 192, a delta of 36%. Passmark DirectX 9: 351 versus 214, a delta of 39%. The Ti is faster in each, but the percentage gap does not widen as dramatically as it does in compute.

Passmark G2D shows a 32.7% delta, with the Ti at 1,332 versus 896. Passmark G3D shows a 38.3% delta, with the Ti at 32,974 versus 20,355. The G3D score is the closest to a general gaming indicator, and it confirms that the Ti is roughly 38% faster in that aggregate metric.

The compute result is the standout. A 59% delta means the Ti is not just faster; it is in a different performance class for GPGPU work. This aligns with the FP32 throughput difference of 13.13 TFLOPS versus 43.94 TFLOPS, a 3.35x raw compute advantage that does not fully translate to the benchmark but still dominates.

Where Each One Wins

The RTX 5070 Ti wins in every workload category recorded: OpenCL, Vulkan, DirectX 9, 10, 11, 12, G2D, G3D, and GPU compute. There are no benchmark wins for the RTX 5070 Mobile in this dataset. The Ti’s strongest relative performance is in GPU compute, where it is 59% ahead. Its weakest relative performance is in DirectX 12, where it is still 26.8% ahead.

For gaming and general 3D rendering, the Ti is the choice. The Passmark G3D score of 32,974 versus 20,355 shows a substantial lead, and the DirectX 12 result confirms it holds up in modern APIs. For users prioritizing portability and low power, the RTX 5070 Mobile has a clear advantage in physical constraints: 50 W TDP, no power connector, and IGP form factor. The Ti cannot fit in such systems at all.

For compute tasks such as machine learning inference, video encoding, or scientific workloads, the Ti’s 59% lead in GPU compute and 42.4% lead in OpenCL make it the only sensible option if power and space allow. The RTX 5070 Mobile’s 8 GB of memory and 384.0 GB/s bandwidth will bottleneck large datasets, while the Ti’s 16 GB and 896.0 GB/s provide far more headroom.

The RTX 5070 Mobile’s niche is thin-and-light laptops where the 50 W envelope and absence of external power are mandatory. In that context, its 75th percentile standing is competitive, matching desktop cards like the RTX 3070 Ti within 0.1%. But in any system that can house the RTX 5070 Ti, the recorded data shows no reason to choose the mobile part.
