NVIDIA GeForce RTX 5070 Mobile vs NVIDIA H100 CNX Comparison

Head-to-Head Benchmarks

The RTX 5070 Mobile has a complete set of recorded benchmark scores, while the H100 CNX has no benchmark data listed in the database. This makes a direct score-by-score comparison impossible. The RTX 5070 Mobile's average benchmark score is 29,928, placing it at the 75th percentile among all GPUs. Its nearest rivals include the RTX 3070 Ti (average score 29,945, delta -0.1%), the RTX 2080 Ti (29,783, delta +0.5%), the RX 6800 (30,095, delta -0.6%), and the RX 6700 (30,433, delta -1.7%). These deltas show the RTX 5070 Mobile sits essentially on par with the RTX 3070 Ti, barely behind the RX 6800 and RX 6700, and slightly ahead of the RTX 2080 Ti.

The H100 CNX, however, has an average benchmark score of 0 and a 50th percentile ranking, with no nearest rivals recorded. The database contains no Geekbench, PassMark, or compute scores for it. This is not a reflection of real-world capability but rather a gap in the recorded measurements. The H100 CNX is a server-oriented part, and the database may not have captured its performance data yet.

Looking at the RTX 5070 Mobile's individual scores, it delivers 122,238 in Geekbench OpenCL and 116,960 in Geekbench Vulkan. These are strong general compute and graphics API results. In PassMark tests, the DirectX 11 score is 192, DirectX 9 is 214, DirectX 10 is 129, and DirectX 12 is 93. The PassMark G3D score is 20,355, while the G2D score is 896. The GPU compute score is 8,279. The spread between G3D and compute indicates the card handles both rasterization and compute workloads reasonably well, though the compute score is relatively modest compared to the G3D number.

Because the H100 CNX has no benchmark entries, there are no head-to-head wins for either card. The winsA and winsB fields are both 0. Any comparison must rely on specification analysis and architectural differences rather than measured performance.

The Verdict

The data shows a clear split between two very different product categories. The RTX 5070 Mobile is a laptop GPU with a 50 W TDP, designed for portable gaming and consumer workloads. Its benchmark scores, while not top-tier, place it in the upper quartile of all GPUs, with performance comparable to desktop cards like the RTX 3070 Ti and RX 6800. For a mobile part drawing only 50 W, this is a notable efficiency achievement. The H100 CNX is a server accelerator with a 350 W TDP, dual-slot cooling, and no display outputs. It is built for datacenter compute, not for end-user graphics.

Who should pick which depends entirely on workload. The RTX 5070 Mobile is the only option here for anyone needing a GPU in a portable device, with display outputs and DirectX 12 Ultimate support. The H100 CNX has no display outputs, no DirectX support, and no Vulkan support, so it cannot function as a consumer graphics card. The H100 CNX is for compute-heavy server environments, but without benchmark data, its exact performance profile cannot be quantified here.

Strictly from the recorded data, the RTX 5070 Mobile is the only one with measurable performance. Its 75th percentile ranking and competitive deltas against desktop GPUs confirm it is a capable mobile part. The H100 CNX's 50th percentile with zero average score is a data artifact, not a performance verdict. The database records no wins for either card, so the verdict must be workload-based: choose the RTX 5070 Mobile for graphics and mobile use, choose the H100 CNX for server compute, but understand that its performance data is not yet in the database.

Where Each One Wins

The RTX 5070 Mobile wins in every category where benchmark data exists. It has measurable scores in Geekbench OpenCL, Vulkan, and all PassMark tests. It wins on pixel rate (68.40 GPixel/s vs 44.28 GPixel/s), which benefits rasterization-heavy workloads. It has more ROPs (48 vs 24), which helps with fill-rate-bound scenarios. It supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, making it a functional graphics card. Its 50 W TDP and IGP form factor make it suitable for portable devices, and its display outputs, while device-dependent, allow for visual output.

The H100 CNX wins in compute specifications. It has 14,592 shading units versus 4,608, 456 TMUs versus 144, and 456 tensor cores versus 144. Its FP32 throughput is 53.84 TFLOPS, over four times the RTX 5070 Mobile's 13.13 TFLOPS. FP16 is 215.4 TFLOPS, over sixteen times higher. Memory bandwidth is 2.04 TB/s versus 384.0 GB/s, and memory capacity is 80 GB versus 8 GB. It also has a higher boost clock (1845 MHz vs 1425 MHz) and higher texture rate (841.3 GTexel/s vs 205.2 GTexel/s).

For use cases, the RTX 5070 Mobile is the clear pick for gaming laptops, portable workstations, or any system requiring graphics output. Its benchmark scores confirm it can handle modern titles and general compute at a level comparable to desktop mid-range cards from the previous generation. The H100 CNX is built for AI training, scientific computing, and large-scale data processing, where its massive memory pool, tensor core count, and FP16 throughput are decisive. However, without benchmark data in the database, its real-world performance cannot be verified here. The data supports the RTX 5070 Mobile for graphics and the H100 CNX for raw compute, but only the RTX 5070 Mobile has recorded evidence of its capabilities.
