NVIDIA H20 NVL16 vs Lisuan Tech LX MAX Comparison

Where Each One Wins

The recorded data separates these two accelerators into entirely different operating domains. The NVIDIA H20 NVL16 is a server-oriented compute module built around the GH100 chip in the Hopper architecture. The Lisuan Tech LX MAX is a dual-slot consumer-adjacent card using the 7G106 chip in the TrueGPU architecture. Neither device has recorded benchmark scores in the database, so the wins are determined by specification dominance rather than measured performance.

The H20 NVL16 wins decisively in memory capacity, memory bandwidth, FP32 throughput, FP16 throughput, texture rate, and transistor count. It carries 96 GB of HBM3 across a 6144-bit bus, delivering 4.03 TB/s. Its FP32 rating is 39.54 TFLOPS, and its FP16 rating is 79.07 TFLOPS. The texture rate reaches 617.8 GTexel/s. The chip contains 80,000 million transistors on an 814 mm² die.

The LX MAX wins in pixel rate, API support, display outputs, and physical adaptability. Its pixel rate is 192.0 GPixel/s, which is substantially higher than the H20's 47.52 GPixel/s. The LX MAX supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.3, while the H20 lists N/A for all three APIs. The LX MAX provides four DisplayPort 1.4a outputs, whereas the H20 has no display outputs at all. The LX MAX uses a PCIe 4.0 x16 interface and fits in a dual-slot form factor with dimensions of 248 mm length, 118 mm height, and 48 mm width.

In compute-centric workloads such as neural network training, large language model inference, or scientific simulation with large memory footprints, the H20 NVL16 is the clear winner based on its memory subsystem and FP16 capabilities. In graphics rendering, pixel-heavy workloads, or any task requiring direct display output, the LX MAX dominates due to its rasterization throughput and API compatibility.

The two devices share the same 50th percentile ranking among all GPUs in the database, though neither has an average benchmark score recorded. Both are listed as Active in production status. The manufacturer for the LX MAX is listed as Unknown, while the H20 comes from NVIDIA.

Architecture Differences

The H20 NVL16 uses the GH100 chip built on a 5 nm process at TSMC. The die measures 814 mm² and contains 80,000 million transistors, yielding a transistor density of 98.3 million per square millimeter. The architecture is Hopper, classified under the Server Hopper (Hxx) generation. Its predecessor is listed as Server Ada, and its successor is Server Blackwell.

The LX MAX uses the 7G106 chip built on a 6 nm process at TSMC. The transistor count and die size are listed as unknown, so no density figure exists in the database. The architecture is TrueGPU, classified under the 7G100 generation. No predecessor or successor is listed.

Clock behavior differs significantly. The H20 NVL16 has a base clock of 1830 MHz and a boost clock of 1980 MHz. Its memory clock is 1313 MHz with 5.3 Gbps effective data rate. The LX MAX has no base or boost clock recorded, but its memory clock is 2250 MHz with 18 Gbps effective. The H20's memory clock is lower in raw frequency, but its HBM3 implementation across a 6144-bit bus produces far higher bandwidth.

The H20 NVL16 contains 9984 shading units, 312 texture mapping units, and 24 raster operations units. It also includes 312 tensor cores. The LX MAX contains 6144 shading units, 192 TMUs, and 96 ROPs. It has no tensor cores listed. This structural difference explains the divergent pixel and texture rates. The LX MAX's 96 ROPs deliver 192.0 GPixel/s, while the H20's 24 ROPs deliver 47.52 GPixel/s. Conversely, the H20's 312 TMUs deliver 617.8 GTexel/s, while the LX MAX's 192 TMUs deliver 384.0 GTexel/s.

The H20 NVL16 draws 400 W and requires an 800 W power supply. It mounts as an SXM Module with a PCIe 5.0 x16 bus interface. The LX MAX draws 225 W, requires a 550 W power supply, uses a single 16-pin power connector, and occupies a dual-slot form factor with a PCIe 4.0 x16 interface.

The API profiles are starkly different. The H20 NVL16 lists DirectX, OpenGL, and Vulkan all as N/A, confirming its compute-only orientation. The LX MAX supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.3, indicating full graphics capability. The H20 has no display outputs; the LX MAX has four DisplayPort 1.4a connectors.

Release dates place the H20 NVL16 in September 2025 and the LX MAX in March 2026. Both are currently Active.

The Verdict

The data indicates two distinct products for two distinct audiences. The NVIDIA H20 NVL16 is a server compute module with no graphics output, no consumer API support, and a massive memory pool. The Lisuan Tech LX MAX is a graphics-capable card with display outputs, full DirectX 12 Ultimate support, and a conventional dual-slot physical design.

For compute workloads that benefit from large memory capacity and high memory bandwidth, the H20 NVL16 is the appropriate choice. Its 96 GB of HBM3 and 4.03 TB/s bandwidth exceed the LX MAX's 12 GB of GDDR6 and 432.0 GB/s by a wide margin. Its FP32 throughput of 39.54 TFLOPS is 60.8% higher than the LX MAX's 24.58 TFLOPS. Its FP16 throughput of 79.07 TFLOPS is 60.9% higher than the LX MAX's 49.15 TFLOPS. The H20's 312 tensor cores provide dedicated hardware for matrix operations, which the LX MAX lacks entirely.

For graphics rendering, rasterization-heavy workloads, or any task requiring direct display output, the LX MAX is the only option between the two. The H20 cannot output video. The LX MAX's pixel rate of 192.0 GPixel/s is 4.04 times the H20's 47.52 GPixel/s. Its API support enables standard graphics application compatibility, while the H20 lists N/A across all three major graphics APIs.

Power requirements favor the LX MAX. It draws 225 W versus the H20's 400 W. The LX MAX requires a 550 W power supply, while the H20 needs an 800 W unit. The LX MAX uses a standard PCIe 4.0 x16 slot and a single 16-pin connector, making it far easier to install in conventional systems. The H20 is an SXM Module, which requires a server chassis with appropriate mounting and cooling infrastructure.

The LX MAX also offers a lower process node at 6 nm versus the H20's 5 nm, though the H20's transistor count of 80,000 million dwarfs the LX MAX's unknown count. The H20's die size of 814 mm² is the largest in the comparison, suggesting a more complex and expensive manufacturing process.

The database shows no benchmark scores for either device, so performance claims must be derived from specifications alone. The percentile ranking for both is 50, indicating median placement among all GPUs, but this ranking carries no average score to substantiate it.

Head-to-Head Benchmarks

The database records no head-to-head benchmark results for this pair, and neither device has an average benchmark score or individual benchmark entries. The wins are therefore determined by comparing the recorded specifications directly.

The largest margin in favor of the H20 NVL16 is memory bandwidth. At 4.03 TB/s, it is 9.33 times the LX MAX's 432.0 GB/s. The HBM3 memory type and 6144-bit bus width enable this advantage. The LX MAX's GDDR6 memory and 192-bit bus cannot approach this throughput.

Memory capacity follows the same pattern. The H20's 96 GB is 8 times the LX MAX's 12 GB. For large models or datasets that exceed 12 GB, the H20 is the only viable option between the two.

FP32 compute favors the H20 by a factor of 1.61. The 39.54 TFLOPS versus 24.58 TFLOPS represents a 60.8% advantage. FP16 compute follows similarly: 79.07 TFLOPS versus 49.15 TFLOPS, a 60.9% advantage. Both devices list FP16 as 2:1 ratio relative to FP32.

Texture rate favors the H20 by a factor of 1.61. The 617.8 GTexel/s versus 384.0 GTexel/s comes from the H20's 312 TMUs versus the LX MAX's 192 TMUs.

The largest margin in favor of the LX MAX is pixel rate. At 192.0 GPixel/s, it is 4.04 times the H20's 47.52 GPixel/s. This advantage stems from the LX MAX's 96 ROPs versus the H20's 24 ROPs.

The LX MAX also leads in memory clock frequency. Its memory clock is 2250 MHz with 18 Gbps effective, versus the H20's 1313 MHz with 5.3 Gbps effective. However, this higher clock does not translate to higher bandwidth due to the narrower bus.

The LX MAX's API support is a complete win. It supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.3. The H20 lists N/A for all three. This makes the LX MAX the only choice for graphics applications that require these APIs.

The LX MAX's display outputs provide another complete win. Four DisplayPort 1.4a connections versus no outputs at all. The H20 cannot drive any display.
