NVIDIA GeForce RTX 4070 AD103 vs NVIDIA H100 CNX Comparison

Head-to-Head Benchmarks

The recorded data shows no direct head-to-head benchmark scores for these two GPUs. The database lists zero wins for each side, and the average benchmark score for both the GeForce RTX 4070 AD103 and the H100 CNX is zero. Both cards sit at the 50th percentile against all GPUs in the database, indicating that neither has a measurable performance edge in the current aggregated results.

Without direct scores, the comparison must rely on raw compute specifications. The H100 CNX delivers 53.84 TFLOPS of FP32 throughput, while the RTX 4070 AD103 delivers 29.15 TFLOPS. That places the H100 CNX roughly 85% ahead in single-precision floating-point work. In FP16, the gap widens dramatically: the H100 CNX reaches 215.4 TFLOPS using a 4:1 ratio, versus 29.15 TFLOPS for the RTX 4070 AD103. That is a 7.4x advantage for the H100 CNX in tensor-heavy workloads, which aligns with its server positioning.

Memory bandwidth tells a similar story. The H100 CNX provides 2.04 TB/s across a 5120-bit HBM2e interface, while the RTX 4070 AD103 offers 504.2 GB/s over a 192-bit GDDR6X bus. The H100 CNX holds a 4x bandwidth lead, which directly impacts data-intensive compute tasks. Texture rate favors the H100 CNX as well: 841.3 GTexel/s versus 455.4 GTexel/s, a 1.85x difference. Pixel rate, however, favors the RTX 4070 AD103: 158.4 GPixel/s versus 44.28 GPixel/s, a 3.6x lead for the GeForce card, reflecting its rasterization focus.

Architecture Differences

The two GPUs come from different NVIDIA architectures. The RTX 4070 AD103 uses Ada Lovelace, while the H100 CNX uses Hopper. Both are built on a 5 nm process at TSMC, but the transistor counts diverge sharply. The H100 CNX packs 80,000 million transistors on an 814 mm² die, while the RTX 4070 AD103 contains 45,900 million transistors on a 379 mm² die. The die size difference is 2.1x, and the transistor count difference is 1.7x. Transistor density favors the RTX 4070 AD103 at 121.1M per mm², versus 98.3M per mm² for the H100 CNX.

Clock behavior differs as well. The RTX 4070 AD103 has a base clock of 1920 MHz and a boost clock of 2475 MHz. The H100 CNX has a base clock of 690 MHz and a boost clock of 1845 MHz. The GeForce card runs at a 630 MHz higher base clock and a 630 MHz higher boost clock. Memory clocks also differ: the RTX 4070 AD103 runs at 1313 MHz with 21 Gbps effective, while the H100 CNX runs at 1593 MHz with 3.2 Gbps effective.

The memory subsystem is fundamentally different. The RTX 4070 AD103 uses GDDR6X with a 192-bit bus, while the H100 CNX uses HBM2e with a 5120-bit bus. The HBM2e stack provides 2.04 TB/s bandwidth, which is 4x the 504.2 GB/s of the GDDR6X setup. The H100 CNX also has 456 tensor cores, which are essential for its FP16 throughput of 215.4 TFLOPS, while the RTX 4070 AD103 has 184 tensor cores and matches its FP16 to FP32 at 29.15 TFLOPS.

Interface and output capabilities separate the two clearly. The RTX 4070 AD103 uses PCIe 4.0 x16 and provides 1x HDMI 2.1 and 3x DisplayPort 1.4a outputs. The H100 CNX uses PCIe 5.0 x16 and provides no display outputs. The H100 CNX is clearly a compute accelerator without video output, while the RTX 4070 AD103 is a consumer graphics card with full display support.

The Verdict

The data indicates two distinct products for different workloads. The RTX 4070 AD103 is a consumer-oriented graphics card with display outputs, a 200 W TDP, and a 599 USD launch MSRP. Its pixel rate of 158.4 GPixel/s exceeds the H100 CNX by 3.6x, and it supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4. The H100 CNX delivers 6.7x more memory capacity, 4x more bandwidth, and 7.4x more FP16 throughput, making it a server compute part with no display outputs and a 350 W TDP.

For rasterization and graphics workloads, the RTX 4070 AD103 is the only option with video outputs and graphics APIs. Its 46 RT cores provide ray tracing capability that the H100 CNX lacks entirely. For FP32 compute, the H100 CNX leads by 85%, and its FP16 advantage is massive. The H100 CNX also has a higher transistor count and larger die, which supports its server positioning. The RTX 4070 AD103 is end-of-life, while the H100 CNX remains active in production. Users needing display output and graphics acceleration should choose the RTX 4070 AD103. Users needing high-bandwidth compute with tensor throughput should choose the H100 CNX.
