NVIDIA H20 vs Lisuan Tech LX 7G100 Comparison

Head-to-Head Benchmarks

The database contains no recorded benchmark scores for either GPU. Both the NVIDIA H20 and the Lisuan Tech LX 7G100 have an average benchmark score of 0, and both sit at the 50th percentile among all GPUs. With no head-to-head benchmark results, the wins must be assessed from architectural specifications and theoretical throughput figures.

The NVIDIA H20 delivers substantially higher compute throughput. Its FP32 performance is 39.54 TFLOPS against the LX 7G100's 24.58 TFLOPS, a 60.9% advantage. In FP16 with 2:1 ratio, the H20 reaches 79.07 TFLOPS versus 49.15 TFLOPS, again roughly 60.9% higher. These are pure arithmetic comparisons from the recorded data.

Memory bandwidth favors the H20 even more decisively. The H20 provides 4.03 TB/s from HBM3 across a 6144-bit bus, while the LX 7G100 manages 432.0 GB/s from GDDR6 across a 192-bit bus. That is a 9.33x difference in raw bandwidth. The H20 also has a larger frame buffer at 96 GB versus 12 GB, an 8x capacity difference.

Texture and pixel throughput split differently. The H20 reaches 617.8 GTexel/s, while the LX 7G100 reaches 384.0 GTexel/s, a 60.9% lead for NVIDIA. However, pixel rate tells the opposite story: the LX 7G100 outputs 192.0 GPixel/s versus 47.52 GPixel/s for the H20, a 4.04x advantage for Lisuan. The LX 7G100 has 96 ROPs compared to just 24 on the H20, while the H20 has 312 TMUs versus 192 on the LX.

The H20 carries 9984 shading units and 312 tensor cores. The LX 7G100 has 6144 shading units and no tensor cores listed. The H20's tensor core count is notable for AI workloads, though no tensor performance figures are recorded.

Clock speeds differ in availability. The H20 lists base 1830 MHz and boost 1980 MHz. The LX 7G100 does not record base or boost clocks. Memory clock shows 1313 MHz with 5.3 Gbps effective for the H20, and 2250 MHz with 18 Gbps effective for the LX.

Where Each One Wins

The NVIDIA H20 wins in compute density, memory capacity, memory bandwidth, texture rate, and transistor count. Its 80,000 million transistors on an 814 mm² die enable 98.3M transistors per mm². The FP32 and FP16 throughput figures position it for heavy parallel compute tasks, particularly those that benefit from large tensor core arrays. The 96 GB HBM3 frame buffer with 4.03 TB/s bandwidth suits workloads holding very large models or datasets in memory.

The Lisuan Tech LX 7G100 wins in pixel throughput, raster operations, display connectivity, and power efficiency. Its 192.0 GPixel/s and 96 ROPs indicate strong traditional rasterization capability. The 4x DisplayPort 1.4a outputs allow direct display connection, while the H20 has no display outputs at all. The LX 7G100 uses 225 W versus 500 W for the H20, and requires a 550 W suggested PSU against 900 W for the H20. The LX also fits a dual-slot PCIe card format at 294 mm length, 120 mm height, and 49 mm width, whereas the H20 is an SXM module.

API support clearly favors the LX 7G100. It lists DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.3. The H20 records N/A for all three APIs, indicating no consumer graphics API support. This makes the LX the only option for conventional graphics workloads.

The LX 7G100 also wins on memory clock speed in raw terms: 2250 MHz versus 1313 MHz, and 18 Gbps effective versus 5.3 Gbps effective. However, the HBM3 bus width more than compensates.

Architecture Differences

The NVIDIA H20 uses the GH100 chip on the Hopper architecture, built on a 5 nm process at TSMC. It belongs to the Server Hopper (Hxx) generation and descends from Server Ada, with Server Blackwell as its successor. The die measures 814 mm² and packs 80,000 million transistors, yielding a density of 98.3M per mm².

The Lisuan Tech LX 7G100 uses the 7G106 chip on the TrueGPU architecture, built on a 6 nm process, also at TSMC. It belongs to the 7G100 generation. Transistor count and die size are not recorded. The LX has no predecessor or successor listed.

Memory architecture diverges completely. The H20 uses HBM3 with a 6144-bit bus and 4.03 TB/s bandwidth. The LX uses GDDR6 with a 192-bit bus and 432.0 GB/s bandwidth. The H20's memory clock is 1313 MHz (5.3 Gbps effective), while the LX runs at 2250 MHz (18 Gbps effective).

Compute resources differ in type and count. The H20 has 9984 shading units, 312 TMUs, 24 ROPs, and 312 tensor cores. The LX has 6144 shading units, 192 TMUs, 96 ROPs, and no tensor cores listed. Neither GPU lists RT cores.

Form factor and interface represent another divide. The H20 is an SXM Module with PCIe 5.0 x16 and no display outputs. The LX is a dual-slot card with PCIe 4.0 x16, a single 8-pin power connector, and 4x DisplayPort 1.4a outputs.

The H20's release date is 2024-01-31, while the LX is dated 2026-06-17. Both are marked Active in production status. Neither has a launch MSRP recorded.

The Verdict

The data shows two GPUs built for different purposes. The NVIDIA H20 is a server compute module with massive memory capacity, high bandwidth, and tensor core support. Its 96 GB HBM3 and 4.03 TB/s bandwidth dwarf the LX's 12 GB and 432.0 GB/s. The H20's FP32 of 39.54 TFLOPS and FP16 of 79.07 TFLOPS make it suited to large-scale parallel compute, AI inference, or training-adjacent workloads where the 500 W power draw and SXM form factor are acceptable.

The Lisuan Tech LX 7G100 is a conventional graphics card. It has display outputs, full DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.3 support. Its 192.0 GPixel/s pixel rate and 96 ROPs indicate strong rasterization throughput for its 225 W power envelope. The 12 GB GDDR6 at 432.0 GB/s is modest but usable for typical graphics tasks. The PCIe 4.0 x16 interface and dual-slot physical design fit standard workstation or consumer systems.

For a user needing a server accelerator with large memory capacity and high bandwidth, the H20 is the clear choice. For a user needing a display-capable GPU with standard graphics APIs and lower power requirements, the LX is the only option between these two. The H20 cannot drive a monitor and lacks graphics API support entirely.

The LX's 4.04x advantage in pixel rate does not compensate for the H20's 9.33x bandwidth lead in compute-centric workloads. Conversely, the H20's lack of display outputs and graphics APIs makes it unsuitable for any interactive or rendering task that requires a screen or DirectX/Vulkan applications.
