NVIDIA GeForce RTX 5070 Ti Mobile vs NVIDIA Rubin GPU Comparison

Head-to-Head Benchmarks

The benchmark comparison between the NVIDIA GeForce RTX 5070 Ti Mobile and the NVIDIA Rubin GPU is severely limited by data availability. The database contains a full suite of nine benchmark results for the RTX 5070 Ti Mobile, while the Rubin GPU has no recorded benchmark scores at all. This asymmetry makes a direct numerical comparison impossible for most tests.

For the RTX 5070 Ti Mobile, the recorded data shows a Geekbench OpenCL score of 143870 and a Geekbench Vulkan score of 139213. The PassMark suite shows results of 151 in DirectX 10, 237 in DirectX 11, 102 in DirectX 12, and 259 in DirectX 9. The GPU compute score sits at 10101, with a G3D score of 24004 and a G2D score of 981. The average benchmark score for the mobile part is 35435.

The Rubin GPU, by contrast, has an average benchmark score of 0 and no entries in any test category. Its percentile ranking among all GPUs is 50, while the RTX 5070 Ti Mobile sits in the 80th percentile. This gap in percentile rank suggests the mobile GPU outperforms the Rubin GPU in the database's overall ranking, but that conclusion derives from the absence of data rather than direct competition.

Looking at the RTX 5070 Ti Mobile's nearest rivals in the database, it trails the AMD Radeon Pro Duo by 1.2% and the NVIDIA T1000 by 2.4%, while leading the NVIDIA Quadro GV100 by 0.2% and the NVIDIA A2 by 2.1%. These deltas are all within a narrow band, indicating the mobile GPU performs at a level comparable to those workstation and data center parts. The Rubin GPU has no nearest rivals listed, so no similar comparison is possible.

Without any recorded benchmarks for the Rubin GPU, the head-to-head analysis must rely on architectural and specification comparisons rather than measured performance. The RTX 5070 Ti Mobile's average score of 35435 versus the Rubin GPU's 0 average score in the database does not reflect real-world capability; it reflects missing data. The percentile difference (80 vs 50) likewise stems from incomplete records.

Architecture Differences

The architectural split between these two GPUs is stark. The RTX 5070 Ti Mobile uses the GB205 chip on a 5 nm process at TSMC, while the Rubin GPU uses the GR100 chip on a 3 nm process, also at TSMC. The mobile part belongs to the Blackwell 2.0 architecture in the GeForce 50 Mobile generation, whereas the Rubin GPU defines the Rubin architecture in the Server Rubin (Rxx) generation.

Transistor counts differ dramatically: the RTX 5070 Ti Mobile packs 31,100 million transistors on a 263 mm² die, yielding a density of 118.3 million transistors per square millimeter. The Rubin GPU contains 336,000 million transistors across a 1456 mm² die, with a density of 230.8 million per square millimeter. That means the Rubin GPU has more than ten times the transistor count and a density nearly double that of the mobile chip.

Memory architecture diverges completely. The RTX 5070 Ti Mobile uses 12 GB of GDDR7 on a 192-bit bus, delivering 672.0 GB/s of bandwidth. The Rubin GPU uses 288 GB of HBM4 across a 16384-bit bus, producing 22.1 TB/s of bandwidth. The Rubin GPU's memory bandwidth is over 30 times higher, and its capacity is 24 times larger.

Compute resources follow the same pattern. The RTX 5070 Ti Mobile has 5888 shading units, 184 texture mapping units, 80 ROPs, 46 RT cores, and 184 tensor cores. The Rubin GPU has 28672 shading units, 896 TMUs, 24 ROPs, and 896 tensor cores. RT core count for the Rubin GPU is not recorded. The Rubin GPU's shading unit count is nearly five times that of the mobile GPU.

Clock speeds tell a different story. The RTX 5070 Ti Mobile runs at a base clock of 847 MHz and boosts to 1447 MHz, with memory at 1750 MHz (28 Gbps effective). The Rubin GPU has a lower base clock of 700 MHz but a much higher boost of 2267 MHz, with memory at 2695 MHz (10.8 Gbps effective). The mobile GPU's higher base clock suggests better sustained low-load performance, while the Rubin GPU's boost clock indicates higher peak capability.

Pixel and texture rates reflect the different design goals. The RTX 5070 Ti Mobile achieves 115.8 GPixel/s and 266.2 GTexel/s. The Rubin GPU delivers 54.41 GPixel/s but 2,031.2 GTexel/s. The mobile GPU has more than double the pixel fill rate, while the Rubin GPU has over seven times the texture rate. FP32 throughput is 17.04 TFLOPS for the mobile GPU versus 130.0 TFLOPS for the Rubin GPU. FP16 is 17.04 TFLOPS (1:1) for the mobile part and 260.0 TFLOPS (2:1) for the Rubin GPU.

Power and physical specifications diverge sharply. The RTX 5070 Ti Mobile has a TDP of 60 W, uses an IGP slot width, requires no power connectors, and is a portable device with display outputs described as portable device dependent. The Rubin GPU has a TDP of 2300 W, uses an SXM Module slot width, suggests a 2700 W PSU, has no display outputs, and uses PCIe 6.0 x16 versus the mobile GPU's PCIe 5.0 x16. The API support also differs: the mobile GPU supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, while the Rubin GPU has no API support recorded.

The Verdict

The data indicates these are fundamentally different products with different purposes. The RTX 5070 Ti Mobile is a consumer mobile GPU with active production status, a release date of 2025-02-28, and a full benchmark profile. The Rubin GPU is a server-class part with active production status, a release date of 2025-12-31, and no benchmark data.

For users seeking a mobile GPU with verified performance, the RTX 5070 Ti Mobile is the only choice with recorded measurements. Its 80th percentile ranking and average score of 35435 demonstrate it performs competitively against workstation GPUs like the NVIDIA Quadro GV100 and AMD Radeon Pro Duo, trailing those parts by less than 2.5%. The mobile GPU also offers features the Rubin GPU lacks entirely: display outputs, DirectX 12 Ultimate support, OpenGL 4.6, and Vulkan 1.4.

For server workloads requiring massive compute and memory, the Rubin GPU's specifications indicate it belongs in a different class. Its 288 GB of HBM4 memory, 22.1 TB/s bandwidth, 130.0 TFLOPS FP32, and 260.0 TFLOPS FP16 dwarf the mobile GPU's capabilities. The 896 tensor cores, 28672 shading units, and 896 TMUs point to extreme parallel throughput. The Rubin GPU also uses a more advanced 3 nm process with higher transistor density.

The percentile data (80 for the mobile GPU, 50 for the Rubin GPU) might suggest the mobile GPU is faster overall, but this reflects missing benchmark data for the Rubin GPU, not actual performance. The database shows zero wins for either GPU in head-to-head benchmarks because no such benchmarks exist.

Users who need a portable, feature-complete GPU with direct display output and broad API support should consider the RTX 5070 Ti Mobile. Users who need server-scale memory bandwidth and compute density should consider the Rubin GPU, though its performance cannot be verified from current data.

The RTX 5070 Ti Mobile uses a smaller die (263 mm² vs 1456 mm²) and fewer transistors (31,100 million vs 336,000 million), making it more appropriate for space-constrained mobile designs. The Rubin GPU's larger die and higher transistor count support server workloads. The mobile GPU has a higher percentile ranking (80 vs 50) and an average benchmark score of 35435, while the Rubin GPU has no benchmark data.

The Rubin GPU wins on process technology with its 3 nm node and higher transistor density (230.8M per mm² vs 118.3M per mm²). It also uses PCIe 6.0 x16 versus PCIe 5.0 x16. The mobile GPU wins on production readiness in the mobile segment, with an earlier release date of 2025-02-28 versus 2025-12-31 for the Rubin GPU.

For gaming or portable graphics workloads, the RTX 5070 Ti Mobile is the only option with verified performance and display support. For server-side compute, AI training, or high-bandwidth memory applications, the Rubin GPU's specifications indicate it is designed for that role, though its benchmark performance remains unverified in the database.
