NVIDIA H20 NVL16 vs Lisuan Tech LX PRO Comparison

The Verdict

The NVIDIA H20 NVL16 and Lisuan Tech LX PRO occupy completely different segments of the GPU market, and the data confirms they are not direct competitors. The H20 NVL16 is a server-oriented accelerator built on the Hopper architecture with a 96 GB HBM3 memory pool, while the LX PRO is a dual-slot workstation card with 24 GB of GDDR6 memory and full display output support. The H20 NVL16 targets compute-heavy workloads that demand massive memory capacity and bandwidth, while the LX PRO serves users who need a conventional graphics card with modern API support. Neither card outperforms the other in a universal sense; each wins in its intended environment. The H20 NVL16 delivers 4.03 TB/s of memory bandwidth versus 432.0 GB/s for the LX PRO, a gap that dominates any memory-bound workload. The LX PRO counters with a higher pixel rate of 192.0 GPixel/s versus 47.52 GPixel/s for the H20 NVL16, making it the better choice for rasterization-focused tasks. The H20 NVL16 has a 50th percentile ranking among all GPUs in the database, and the LX PRO also sits at the 50th percentile, but this parity masks the fact that the two cards target entirely different application spaces. The H20 NVL16 is the pick for server deployments where memory capacity and bandwidth are paramount. The LX PRO is the pick for a desktop workstation that needs display outputs, DirectX 12 Ultimate support, and a smaller physical footprint.

Architecture Differences

The H20 NVL16 uses the GH100 chip built on a 5 nm process at TSMC with 80,000 million transistors on an 814 mm² die. The LX PRO uses the 7G105 chip on a 6 nm process, also from TSMC, though its transistor count and die size are not recorded in the database. The H20 NVL16 belongs to the Hopper architecture and the Server Hopper (Hxx) generation, while the LX PRO uses the TrueGPU architecture from the 7G100 generation. The H20 NVL16 has no display outputs and declares its DirectX, OpenGL, and Vulkan APIs as N/A, confirming it is a compute accelerator rather than a graphics card. The LX PRO supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.3, and provides 4x DisplayPort 1.4a outputs, making it a fully functional graphics solution.

The memory subsystems differ fundamentally. The H20 NVL16 uses 96 GB of HBM3 across a 6144-bit bus, yielding 4.03 TB/s of bandwidth. The LX PRO uses 24 GB of GDDR6 across a 192-bit bus, yielding 432.0 GB/s of bandwidth. The H20 NVL16 has a memory clock of 1313 MHz with 5.3 Gbps effective data rate, while the LX PRO has a memory clock of 2250 MHz with 18 Gbps effective data rate. The H20 NVL16 relies on 312 tensor cores to accelerate AI and deep learning operations, a feature the LX PRO does not list. The H20 NVL16 has no RT cores listed, and the LX PRO also has no RT cores listed, so neither card carries dedicated ray tracing hardware according to the database.

The H20 NVL16 uses an SXM module form factor, which means it is not a standard PCIe card you slot into a desktop motherboard. The LX PRO is a dual-slot card with a 248 mm length, 118 mm height, and 48 mm width, and it draws power from a single 16-pin connector. The H20 NVL16 has a 400 W TDP with a suggested power supply of 800 W, while the LX PRO has a 225 W TDP with a suggested power supply of 550 W. The H20 NVL16 connects via PCIe 5.0 x16, while the LX PRO uses PCIe 4.0 x16. The H20 NVL16 has no power connector listed because the SXM module receives power through the server chassis.

Where Each One Wins

Benchmark results show the H20 NVL16 wins in any scenario that stresses memory capacity or bandwidth. The 96 GB HBM3 pool with 4.03 TB/s bandwidth is an order of magnitude larger and faster than the LX PRO's 24 GB GDDR6 with 432.0 GB/s. Large language model inference, scientific simulation, and data analytics workloads that exceed 24 GB of working set will simply not fit on the LX PRO, while the H20 NVL16 has room to spare. The H20 NVL16 also delivers 39.54 TFLOPS of FP32 performance and 79.07 TFLOPS of FP16 performance, both higher than the LX PRO's 24.58 TFLOPS FP32 and 49.15 TFLOPS FP16. The H20 NVL16 also carries 312 tensor cores, which the LX PRO lacks entirely, giving the H20 NVL16 a decisive advantage in matrix math and AI inference.

The LX PRO wins in rasterization and display-centric workloads. Its pixel rate of 192.0 GPixel/s is more than four times the H20 NVL16's 47.52 GPixel/s. Its texture rate of 384.0 GTexel/s trails the H20 NVL16's 617.8 GTexel/s, but the LX PRO's ROP count of 96 versus 24 for the H20 NVL16 means the LX PRO can push pixels to a screen far more effectively. The LX PRO has 4x DisplayPort 1.4a outputs, while the H20 NVL16 has none, so the LX PRO is the only one of the two that can drive a monitor. The LX PRO supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.3, making it suitable for gaming and interactive graphics, while the H20 NVL16 lists N/A for all graphics APIs. The LX PRO also uses less power at 225 W versus 400 W, and it fits in a standard dual-slot PCIe card format, making it far easier to deploy in a desktop workstation.

Head-to-Head Benchmarks

The database shows no direct head-to-head benchmark scores between the H20 NVL16 and the LX PRO, but the recorded specifications allow for a clear comparison across key metrics. The H20 NVL16 wins the memory bandwidth contest decisively: 4.03 TB/s versus 432.0 GB/s, a 9.3x advantage. This translates directly to performance in memory-bound workloads, where the H20 NVL16 can feed its compute units far more quickly. The H20 NVL16 also wins in FP32 throughput with 39.54 TFLOPS versus 24.58 TFLOPS, a 60.9% lead. In FP16, the H20 NVL16 delivers 79.07 TFLOPS versus 49.15 TFLOPS, a 60.9% lead as well.
