NVIDIA H20 vs Lisuan Tech LX PRO Comparison

NVIDIA H20 and Lisuan Tech LX PRO occupy very different positions in the database. The H20 is a server-focused accelerator built on the GH100 chip with 80,000 million transistors, while the LX PRO is a dual-slot graphics card using the 7G105 chip. Despite both being active production parts, their architectural goals, memory systems, and feature sets diverge sharply. The recorded data shows no shared benchmark scores, so the comparison relies entirely on specification analysis and the limited percentile data available.

Head-to-Head Benchmarks

The database contains no direct benchmark results for either the NVIDIA H20 or the Lisuan Tech LX PRO. Both products show an average benchmark score of 0 and a percentile of 50 against all GPUs, indicating that neither has accumulated measurable workload performance data in the current records. Without benchmark scores, the comparison must focus on the theoretical compute and memory metrics provided in the specification sheets.

In raw floating-point throughput, the NVIDIA H20 delivers 39.54 TFLOPS for FP32 operations, while the LX PRO produces 24.58 TFLOPS. This gives the H20 a 60.9% higher FP32 figure based on the recorded numbers. For FP16 with a 2:1 ratio, the H20 reaches 79.07 TFLOPS versus 49.15 TFLOPS for the LX PRO, a 60.9% advantage that mirrors the FP32 gap due to identical ratio scaling.

The pixel and texture rates tell a different story. The LX PRO outputs 192.0 GPixel/s, which is 4.04 times the H20’s 47.52 GPixel/s. The LX PRO also leads in texture rate with 384.0 GTexel/s compared to 617.8 GTexel/s for the H20, meaning the H20 actually holds a 60.9% lead in texel throughput. The H20’s advantage comes from its 312 texture mapping units and 9984 shading units, while the LX PRO’s higher pixel rate stems from 96 raster output units versus only 24 on the H20.

Memory bandwidth heavily favors the H20. The H20 uses 96 GB of HBM3 across a 6144-bit bus, delivering 4.03 TB/s. The LX PRO uses 24 GB of GDDR6 on a 192-bit bus, reaching 432.0 GB/s. The H20’s bandwidth is 9.33 times higher. Memory clock speeds also differ, with the H20 running at 1313 MHz (5.3 Gbps effective) and the LX PRO at 2250 MHz (18 Gbps effective). The LX PRO’s faster per-pin speed does not compensate for the much narrower bus.

Architecture Differences

The NVIDIA H20 is built on the Hopper architecture using a 5 nm process at TSMC. Its GH100 chip contains 80,000 million transistors on an 814 mm² die, yielding a transistor density of 98.3 million per mm². The LX PRO uses the TrueGPU architecture on a 6 nm process, also from TSMC, but the database lists its transistor count and die size as unknown. This makes a direct density comparison impossible, though the process node difference suggests the H20 uses a more advanced manufacturing technology.

The H20 is a server accelerator with an SXM module slot width, no display outputs, and no support for DirectX, OpenGL, or Vulkan APIs. It is designed for compute workloads without any graphics output capability. The LX PRO is a dual-slot card with 4x DisplayPort 1.4a outputs, supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.3, and uses a PCIe 4.0 x16 interface. The H20 uses PCIe 5.0 x16, offering a newer bus generation.

The H20 includes 312 tensor cores, a feature absent from the LX PRO’s specification sheet, which lists no tensor core count. Both cards lack dedicated ray tracing cores, as the database records null values for RT cores on both products. The H20’s shading unit count is 9984, while the LX PRO has 6144. The texture mapping units number 312 for the H20 and 192 for the LX PRO, while the raster output units are 24 and 96, respectively.

Power and cooling requirements differ substantially. The H20 has a TDP of 500 W and requires a 900 W suggested PSU. The LX PRO has a TDP of 225 W and needs a 550 W suggested PSU. The H20 uses no power connectors in the listed data, while the LX PRO uses a single 16-pin connector. The H20’s higher TDP aligns with its larger memory capacity and bandwidth, while the LX PRO’s lower power draw suits its smaller footprint.

The H20 measures no dimensions in the database, but its SXM module form factor indicates a non-standard server mounting. The LX PRO has recorded dimensions of 248 mm in length, 118 mm in height, and 48 mm in width, equivalent to 9.8 inches by 4.6 inches by 1.9 inches. The H20’s release date is recorded as 2024-01-31, while the LX PRO’s release date is 2026-03-16. The H20 lists a predecessor as Server Ada and a successor as Server Blackwell, while the LX PRO has no predecessor or successor in the records.

The Verdict

The recorded data indicates two products with opposite design priorities. The NVIDIA H20 is a server accelerator with massive memory capacity and bandwidth, high FP32 and FP16 throughput, and tensor cores for specialized compute workloads. It lacks any graphics output or consumer API support, making it unsuitable for display-based tasks. The Lisuan Tech LX PRO is a dual-slot graphics card with display outputs, full DirectX 12 Ultimate support, and a higher pixel rate, positioning it for rendering and graphics-oriented applications.

For compute-heavy tasks that benefit from large memory pools and high bandwidth, the H20’s 96 GB HBM3 with 4.03 TB/s and 312 tensor cores provide a clear advantage. Its 39.54 TFLOPS FP32 and 79.07 TFLOPS FP16 figures exceed the LX PRO’s corresponding 24.58 and 49.15 TFLOPS by 60.9%. The 500 W TDP and 900 W suggested PSU reflect the H20’s higher power envelope.

For graphics workloads requiring rasterization output, the LX PRO’s 192.0 GPixel/s and 96 ROPs outperform the H20’s 47.52 GPixel/s and 24 ROPs. The LX PRO’s display outputs and API support enable direct video output, which the H20 cannot provide. Its lower 225 W TDP and 550 W suggested PSU make it suitable for standard desktop installations. The choice depends entirely on whether the workload demands server-class memory bandwidth or graphics-oriented pixel throughput.
