NVIDIA GB10 vs NVIDIA GeForce RTX 4070 AD103 Comparison

Head-to-Head Benchmarks

The recorded data contains only two benchmark results for the NVIDIA GB10, both from Geekbench. The NVIDIA GeForce RTX 4070 AD103 has no recorded benchmark scores in the database, which makes a direct head-to-head comparison incomplete. The GB10 scores 120,137 points in Geekbench OpenCL and 114,648 points in Geekbench Vulkan. Its average benchmark score across available tests is 117,393 points, placing it in the 95th percentile of all GPUs tracked in the database.

Without any recorded scores for the RTX 4070 AD103, the comparison must rely on the GB10's nearest rivals to establish a performance context. The GB10 sits 0.3% above the NVIDIA RTX 4000 SFF Ada Generation, which averages 117,088 points. It trails the AMD Radeon PRO W7700 by 1.3%, which averages 118,976 points. Against older data-center parts, the GB10 is 2.6% ahead of the NVIDIA Tesla V100 SXM2 16 GB (114,395 points) and 3% ahead of the NVIDIA RTX A5500 Mobile (113,944 points). These deltas are small, indicating that the GB10 clusters tightly with mid-range workstation and data-center accelerators.

The RTX 4070 AD103, by contrast, has an average benchmark score of zero and a 50th percentile rank, meaning the database holds no verified performance measurements for this specific SKU. The absence of scores does not indicate a failure of the hardware; it simply means no benchmark submissions exist in the dataset. Consequently, the biggest wins in this comparison are entirely one-sided: the GB10 delivers measurable performance in both OpenCL and Vulkan, while the RTX 4070 AD103 offers no recorded data points to compare.

The GB10's nearest rivals show that its performance is competitive but not dominant. A 0.3% edge over the RTX 4000 SFF Ada Generation is within measurement noise, while the 1.3% deficit to the AMD Radeon PRO W7700 suggests the GB10 is slightly behind that particular workstation card. The 2.6% and 3% advantages over the Tesla V100 and RTX A5500 Mobile, respectively, indicate a generational improvement over older architectures, but the margins remain modest.

The Verdict

From the available data, the NVIDIA GB10 is the only one of the two with verified benchmark scores. Its 95th percentile ranking and average score of 117,393 points place it firmly in the upper tier of GPUs in the database, comparable to recent workstation accelerators. The GB10 delivers 29.71 TFLOPS of FP32 performance and 29.71 TFLOPS of FP16 performance, matching the RTX 4070 AD103's 29.15 TFLOPS in both metrics. The GB10 also carries 128 GB of LPDDR5X memory, a massive capacity advantage over the RTX 4070 AD103's 12 GB of GDDR6X.

For users relying on benchmark data, the GB10 is the only option with measurable results. The RTX 4070 AD103 cannot be assessed through the database because no scores are recorded. The GB10's nearest rivals, all scoring within 3% of its average, suggest that it occupies a performance tier similar to professional workstation cards like the RTX 4000 SFF Ada Generation and the AMD Radeon PRO W7700.

The RTX 4070 AD103, despite its lack of recorded benchmarks, has a 50th percentile rank across all GPUs, which is a database-wide placement based on its specifications and known characteristics. However, without a concrete average score, the verdict must favor the GB10 based purely on the evidence available. The GB10 is an active product with a 95th percentile ranking, while the RTX 4070 AD103 is end-of-life and has no measured performance data.
