NVIDIA H20 NVL16 vs Lisuan Tech LX 7G100 Comparison

Head-to-Head Benchmarks

The recorded data for the NVIDIA H20 NVL16 and the Lisuan Tech LX 7G100 shows no direct head-to-head benchmark scores or wins for either part. The benchmark database lists zero entries for both accelerators, and their average benchmark scores are 0. Both GPUs sit at the 50th percentile versus all GPUs, which indicates that without measured workloads, the comparative performance between these two parts cannot be quantified using scoring data. The absence of nearest rivals for either item further isolates them from comparative analysis.

What can be stated from the raw compute figures is that the NVIDIA H20 NVL16 delivers 39.54 TFLOPS of FP32 performance and 79.07 TFLOPS of FP16 performance (2:1). The Lisuan Tech LX 7G100 delivers 24.58 TFLOPS of FP32 performance and 49.15 TFLOPS of FP16 performance (2:1). This means the NVIDIA part holds a 60.9% advantage in FP32 and a 60.9% advantage in FP16 based solely on the listed specifications. The texture rate for the H20 NVL16 is 617.8 GTexel/s, compared to 384.0 GTexel/s for the LX 7G100, which places the NVIDIA part 60.9% ahead here as well. However, the pixel rate tells the opposite story: the LX 7G100 achieves 192.0 GPixel/s, while the H20 NVL16 reaches only 47.52 GPixel/s, making the Lisuan part 304% faster in pixel throughput.

Memory capacity and bandwidth also diverge sharply. The H20 NVL16 uses 96 GB of HBM3 on a 6144-bit bus, delivering 4.03 TB/s of bandwidth. The LX 7G100 uses 12 GB of GDDR6 on a 192-bit bus, delivering 432.0 GB/s. The NVIDIA accelerator provides 8 times the memory capacity and roughly 8.3 times the memory bandwidth. Clock speeds favor the H20 NVL16 on the core side, with a base clock of 1830 MHz and a boost clock of 1980 MHz, while the LX 7G100 has no base or boost clock listed. Memory clocks differ as well: the H20 NVL16 runs at 1313 MHz (5.3 Gbps effective), while the LX 7G100 runs at 2250 MHz (18 Gbps effective), indicating the GDDR6 memory operates at a higher effective data rate despite the lower overall bandwidth.

The Verdict

The data indicates two accelerators built for entirely different purposes. The NVIDIA H20 NVL16 is a server module with a 400 W TDP, an SXM form factor, and no display outputs. It is designed for compute-heavy environments that prioritize FP32, FP16, and memory bandwidth above all else. The Lisuan Tech LX 7G100 is a dual-slot PCIe card with a 225 W TDP, 4x DisplayPort 1.4a outputs, and support for DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.3. Its higher pixel rate and display outputs suggest a role in graphics rendering or visualization workloads rather than pure compute.

For users whose workloads depend on FP32 throughput, FP16 throughput, texture rate, or massive memory pools, the H20 NVL16 is the clear choice from the specification data. For tasks that require rasterization throughput, pixel processing, or direct display output, the LX 7G100 shows measurable advantages. The benchmark database provides no scores to override these specification-based conclusions, so any decision must rest on the listed hardware capabilities. The absence of launch MSRP values for both parts removes pricing from the analysis entirely.
