NVIDIA GB10 vs NVIDIA GeForce RTX 5070 Ti Mobile Comparison

The Verdict

The benchmark database places these two NVIDIA Blackwell 2.0 parts in different performance tiers despite sharing the same architecture generation. The NVIDIA GeForce RTX 5070 Ti Mobile wins both recorded head-to-head comparisons, taking Geekbench OpenCL by 16.5% and Geekbench Vulkan by 17.6%. The NVIDIA GB10, however, holds the higher overall percentile ranking at 95 versus 80 for the mobile part, reflecting a broader benchmark suite where the GB10's average score of 117,393 places it near workstation and server-class competitors. The RTX 5070 Ti Mobile's average score of 35,435 is dragged down by its Passmark results, which include a G3D score of 24,004 and a GPU Compute score of 10,101, while the GB10 only has Geekbench entries recorded.

The data indicates a clear split: the RTX 5070 Ti Mobile delivers superior raw compute in the two tests where both were measured, while the GB10 demonstrates consistency across a wider range of professional workloads. The GB10's nearest rivals include the NVIDIA RTX 4000 SFF Ada Generation at 0.3% behind, the AMD Radeon PRO W7700 at 1.3% ahead, and the NVIDIA Tesla V100 SXM2 16 GB at 2.6% behind, suggesting it competes in dense workstation territory. The RTX 5070 Ti Mobile sits near the NVIDIA Quadro GV100 at 0.2% behind, the AMD Radeon Pro Duo at 1.2% ahead, and the NVIDIA A2 at 2.1% behind. For users prioritizing the two Geekbench compute tests, the mobile part is the clear winner. For those needing a broader professional profile with higher percentile standing, the GB10's dataset shows more consistent placement.

Architecture Differences

Both chips use the Blackwell 2.0 architecture fabricated on TSMC's 5 nm process, but they diverge substantially in physical configuration. The GB10 uses the GB20B chip with a die size of 382 mm², while the RTX 5070 Ti Mobile uses the GB205 chip at 263 mm². The RTX 5070 Ti Mobile reports 31,100 million transistors and a transistor density of 118.3M per mm²; the GB10's transistor count is not recorded in the database. The GB10 carries 6144 shading units, 384 texture mapping units, 48 ROPs, 48 ray tracing cores, and 384 tensor cores. The RTX 5070 Ti Mobile has 5888 shading units, 184 TMUs, 80 ROPs, 46 RT cores, and 184 tensor cores. The GB10 therefore fields more shaders, TMUs, RT cores, and tensor cores, while the mobile part has substantially more ROPs.

Memory architecture differs completely. The GB10 uses 128 GB of LPDDR5X on a 256-bit bus delivering 273.2 GB/s of bandwidth. The RTX 5070 Ti Mobile uses 12 GB of GDDR7 on a 192-bit bus delivering 672.0 GB/s. The mobile part has nearly 2.5 times the bandwidth despite a narrower bus, while the GB10 has over ten times the capacity. Clock behavior also separates them: the GB10 runs a base of 1665 MHz and boosts to 2418 MHz, while the RTX 5070 Ti Mobile runs a much lower base of 847 MHz and boosts to 1447 MHz. The GB10's higher clocks contribute to its FP32 throughput of 29.71 TFLOPS versus 17.04 TFLOPS for the mobile part, both at 1:1 FP16. Pixel rates are nearly identical at 116.1 GPixel/s for the GB10 and 115.8 GPixel/s for the mobile chip, but texture rates diverge sharply: 928.5 GTexel/s versus 266.2 GTexel/s.

Power and interface data show the GB10 rated at 140 W TDP with a suggested 300 W PSU, while the RTX 5070 Ti Mobile is rated at only 60 W TDP with no suggested PSU recorded. Both use PCIe 5.0 x16. The GB10 outputs 1x HDMI, while the mobile part's display outputs are portable device dependent. API support differs: the GB10 lists N/A for DirectX, OpenGL, and Vulkan, whereas the RTX 5070 Ti Mobile supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The GB10's release date is 2025-10-14, the mobile part's is 2025-02-28. The GB10 has a recorded launch MSRP of 3,999 USD; the mobile part has none.

Head-to-Head Benchmarks

The only two direct comparisons in the database both favor the NVIDIA GeForce RTX 5070 Ti Mobile. In Geekbench OpenCL, the mobile part scores 143,870 against the GB10's 120,137, a delta of 16.5%. In Geekbench Vulkan, the mobile part scores 139,213 against the GB10's 114,648, a delta of 17.6%. These results indicate that in compute-heavy API workloads, the mobile chip's higher memory bandwidth (672.0 GB/s) and GDDR7 memory provide a measurable advantage over the GB10's LPDDR5X at 273.2 GB/s, despite the GB10's higher FP32 TFLOPS and higher clock speeds.

The GB10 does not win either recorded head-to-head test. Its wins column shows zero, while the mobile part shows two. This is a striking outcome given the GB10's superior shading unit count, tensor core count, and FP32 throughput. The data suggests that the GB10's architectural strengths in texture rate and raw shader count do not translate into Geekbench compute wins, possibly because the RTX 5070 Ti Mobile's memory subsystem delivers data faster to the compute units. The GB10's percentile of 95 versus the mobile part's 80 indicates that when the full benchmark set is considered, the GB10 places higher among all GPUs, but that percentile is built on a different set of tests (only two Geekbench entries) versus the mobile part's nine recorded tests.

The nearest rival data reinforces the split. The GB10's closest competitor is the NVIDIA RTX 4000 SFF Ada Generation at 0.3% behind, then the AMD Radeon PRO W7700 at 1.3% ahead, the NVIDIA Tesla V100 SXM2 16 GB at 2.6% behind, and the NVIDIA RTX A5500 Mobile at 3% behind. The RTX 5070 Ti Mobile's closest rival is the NVIDIA Quadro GV100 at 0.2% behind, then the AMD Radeon Pro Duo at 1.2% ahead, the NVIDIA A2 at 2.1% behind, and the NVIDIA T1000 at 2.4% behind. These clusters place the GB10 among modern workstation accelerators, while the mobile part sits near older high-end and entry-level professional cards.

Where Each One Wins

The RTX 5070 Ti Mobile wins in compute benchmark performance as recorded by Geekbench OpenCL and Vulkan, scoring 143,870 and 139,213 respectively. Its 672.0 GB/s memory bandwidth and GDDR7 memory type give it a decisive edge in these tests, and its lower 60 W TDP makes it suitable for portable configurations. The mobile part also supports modern graphics APIs including DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, which the GB10 lacks entirely. Its higher ROP count of 80 versus 48 suggests advantages in rasterization-bound scenarios, though pixel rates are nearly equal.

The GB10 wins in overall percentile ranking, sitting at 95 versus 80 for the mobile part. Its average benchmark score of 117,393 places it among workstation and server accelerators like the NVIDIA RTX 4000 SFF Ada Generation and AMD Radeon PRO W7700. The GB10's 128 GB memory capacity dwarfs the mobile part's 12 GB, making it the choice for large datasets. Its FP32 throughput of 29.71 TFLOPS is 74% higher than the mobile part's 17.04 TFLOPS, and its texture rate of 928.5 GTexel/s is more than triple the mobile part's 266.2 GTexel/s. The GB10 also has more shading units (6144 versus 5888), more TMUs (384 versus 184), more RT cores (48 versus 46), and more tensor cores (384 versus 184). Its 140 W TDP and 300 W suggested PSU indicate a desktop or server IGP design with no power connectors listed.

For workloads measured by Passmark, only the mobile part has data. Its Passmark G3D score is 24,004 and GPU Compute is 10,101, with DirectX 12 at 102, DirectX 11 at 237, DirectX 10 at 151, DirectX 9 at 259, and G2D at 981. These numbers are not compared against the GB10 since no Passmark results exist for it. The mobile part's percentile of 80 still places it above the majority of GPUs in the database.
