NVIDIA H100 SXM5 64 GB vs Lisuan Tech LX PRO Comparison

The Verdict

The recorded data positions these two accelerators at opposite ends of the compute spectrum. The NVIDIA H100 SXM5 64 GB is a data-center-scale server module built for massive parallel throughput, while the Lisuan Tech LX PRO is a dual-slot, display-capable workstation card with a lower power envelope. Benchmark results are absent from the database, so the verdict rests entirely on architectural and specification differences. The H100 delivers the higher raw compute density and memory bandwidth, making it the choice for large-scale AI training and HPC workloads. The LX PRO offers a more accessible power profile and full display outputs, suiting it for desktop GPU compute, visualization, and tasks where PCIe 4.0 connectivity and a smaller physical footprint are sufficient. Neither card has recorded benchmark scores, and both sit at the 50th percentile among all GPUs in the database, indicating no measured performance edge from the available data.

Architecture Differences

The NVIDIA H100 SXM5 64 GB uses the GH100 chip built on a 5 nm process at TSMC, with 80,000 million transistors packed into an 814 mm² die. Its transistor density reaches 98.3M per mm². The architecture is Hopper, generation "Server Hopper (Hxx)", and the card is an SXM Module with an 8-pin EPS power connector and a suggested 1100 W power supply. It has no display outputs, which aligns with its server role. The LX PRO uses the 7G105 chip on a 6 nm TSMC process, with transistor count and die size listed as unknown. Its architecture is TrueGPU, generation 7G100, and it is a dual-slot card with a 1x 16-pin power connector and a suggested 550 W power supply. It provides 4x DisplayPort 1.4a outputs and supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.3, while the H100 lists no API support in the database.

The H100 features 16,896 shading units, 528 TMUs, and 24 ROPs, with 528 tensor cores. The LX PRO has 6,144 shading units, 192 TMUs, and 96 ROPs, with no tensor cores listed.

The H100's FP32 throughput is 66.91 TFLOPS, and FP16 is 267.6 TFLOPS (4:1). The LX PRO's FP32 is 24.58 TFLOPS, and FP16 is 49.15 TFLOPS (2:1). The H100's memory clock is 1313 MHz with 5.3 Gbps effective, while the LX PRO's memory clock is 2250 MHz with 18 Gbps effective. The H100 relies on HBM3 memory, while the LX PRO uses GDDR6.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries, no wins for either card, and no average benchmark scores. Therefore, no measured performance comparisons can be drawn from the recorded data. The analysis must instead interpret the specification differences as proxies for capability. The H100's FP32 throughput of 66.91 TFLOPS is approximately 2.7 times the LX PRO's 24.58 TFLOPS, indicating a substantial lead in single-precision compute for the H100. The H100's FP16 performance of 267.6 TFLOPS (4:1) is over 5 times the LX PRO's 49.15 TFLOPS (2:1), suggesting a major advantage in mixed-precision workloads such as AI inference and training. The H100's memory bandwidth of 2.02 TB/s dwarfs the LX PRO's 432.0 GB/s, a difference of roughly 4.7 times, which directly impacts memory-bound applications.

The LX PRO counters in other areas. Its pixel rate of 192.0 GPixel/s is 4 times the H100's 47.52 GPixel/s, indicating a strong rasterization throughput advantage. Its ROP count of 96 is 4 times the H100's 24, which supports the higher pixel rate. The LX PRO also has a higher memory clock at 2250 MHz versus 1313 MHz, and a faster effective memory speed of 18 Gbps versus 5.3 Gbps. The LX PRO's texture rate of 384.0 GTexel/s is lower than the H100's 1,045.4 GTexel/s, but the LX PRO's TMU count of 192 versus 528 explains the gap. The LX PRO's FP16 ratio is 2:1, while the H100's is 4:1, meaning the H100 dedicates more hardware to FP16 operations.
