NVIDIA H800 PCIe 80 GB vs Lisuan Tech LX PRO Comparison

Head-to-Head Benchmarks

The recorded database contains no head-to-head benchmark entries for this pairing. Both the NVIDIA H800 PCIe 80 GB and the Lisuan Tech LX PRO have an average benchmark score of 0, and neither has any benchmark results listed. The wins tally shows 0 for each product, indicating no direct comparison data has been captured.

With no measured performance results available, the only quantitative comparison possible comes from the theoretical throughput figures in the specification records. In FP32 compute, the H800 delivers 51.22 TFLOPS, which is 2.08 times the 24.58 TFLOPS of the LX PRO. The H800 also leads in FP16, posting 204.9 TFLOPS (4:1) against 49.15 TFLOPS (2:1) for the LX PRO, a 4.17 times advantage. These figures represent peak rates rather than real-world application results, so they indicate relative compute ceilings rather than actual benchmark outcomes.

Memory bandwidth heavily favors the H800. Its HBM2e stack provides 2.04 TB/s across a 5120-bit bus, compared to 432.0 GB/s on the LX PRO's 192-bit GDDR6 interface. That is a 4.72 times difference in raw bandwidth. The H800 also carries 80 GB of memory versus 24 GB, a 3.33 times capacity advantage. Texture rate favors the H800 at 800.3 GTexel/s versus 384.0 GTexel/s, a 2.08 times margin. Pixel rate, however, goes the other way: the LX PRO reaches 192.0 GPixel/s, while the H800 manages 42.12 GPixel/s. The H800's pixel rate is only 0.22 times that of the LX PRO, which reflects the very different rasterization focus of the two designs.

Both cards sit at the 50th percentile among all GPUs in the database, with no rival comparisons provided. The absence of benchmark data means the percentile values are placeholder indicators rather than results derived from actual test runs.

Architecture Differences

The NVIDIA H800 PCIe 80 GB is built on the Hopper architecture with the GH100 chip, belonging to the Server Hopper (Hxx) generation. The Lisuan Tech LX PRO uses the TrueGPU architecture with the 7G105 chip from the 7G100 generation. These are fundamentally different design families: Hopper is a server-oriented compute architecture, while TrueGPU appears oriented toward general graphics and compute workloads.

Process technology differs. The H800 uses a 5 nm TSMC node, while the LX PRO uses 6 nm TSMC. The H800 integrates 80,000 million transistors on a die of 814 mm², producing a transistor density of 98.3M per mm². The LX PRO's transistor count and die size are recorded as unknown, so no density figure exists.

Shader organization differs substantially. The H800 has 14,592 shading units, 456 TMUs, and 24 ROPs. The LX PRO has 6,144 shading units, 192 TMUs, and 96 ROPs. The H800 has 2.38 times more shading units and 2.38 times more TMUs, but the LX PRO has 4 times more ROPs. This distribution indicates the H800 prioritizes compute throughput, while the LX PRO allocates more hardware to pixel output.

The H800 includes 456 tensor cores; the LX PRO records no tensor core count. The H800's FP16 figure of 204.9 TFLOPS (4:1) benefits from these tensor cores, which are absent from the LX PRO's specification sheet. The LX PRO's FP16 of 49.15 TFLOPS (2:1) reflects a simpler ratio, suggesting a different execution path.

Memory architecture is entirely different. The H800 uses HBM2e with a 5120-bit bus and 2.04 TB/s bandwidth. The LX PRO uses GDDR6 with a 192-bit bus and 432.0 GB/s bandwidth. The H800's memory clock is listed as 1593 MHz with 3.2 Gbps effective, while the LX PRO runs at 2250 MHz with 18 Gbps effective. The HBM2e design favors capacity and bandwidth, while GDDR6 favors lower cost and simpler implementation.

The H800 has no display outputs; the LX PRO has 4x DisplayPort 1.4a. The H800 does not list DirectX, OpenGL, or Vulkan API support. The LX PRO supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.3. This confirms the H800 is a compute accelerator without graphics output, while the LX PRO is a full graphics card.

Bus interface differs: the H800 uses PCIe 5.0 x16, the LX PRO uses PCIe 4.0 x16. Power requirements also differ: the H800 has a TDP of 350 W with a suggested PSU of 750 W, while the LX PRO has a TDP of 225 W with a suggested PSU of 550 W.

Physical dimensions differ. The H800 measures 268 mm in length and 111 mm in height. The LX PRO measures 248 mm in length, 118 mm in height, and 48 mm in width. Both are dual-slot cards with a single 16-pin power connector.

The Verdict

The recorded data shows two products with no benchmark results, so any selection guidance must rely on specification differences rather than measured performance.

The NVIDIA H800 PCIe 80 GB is positioned for compute-heavy workloads requiring large memory capacity and enormous bandwidth. Its 80 GB HBM2e pool, 2.04 TB/s bandwidth, 51.22 TFLOPS FP32, and 204.9 TFLOPS FP16 with tensor cores place it in a category for large-scale data processing, AI training, and scientific computing. The absence of display outputs and API listings confirms it is not intended for graphics output. Its 350 W TDP and 750 W suggested PSU indicate a data-center power profile.

The Lisuan Tech LX PRO is a more conventional graphics card. It has 24 GB GDDR6, 432.0 GB/s bandwidth, 24.58 TFLOPS FP32, and 49.15 TFLOPS FP16. It provides 4x DisplayPort 1.4a and full DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.3 support. Its 192.0 GPixel/s pixel rate is 4.56 times higher than the H800, and its 96 ROPs give it 4 times the ROP count. Its 225 W TDP and 550 W suggested PSU make it more modest in power requirements.

For pure compute throughput, the database clearly favors the H800 in FP32, FP16, texture rate, memory bandwidth, and memory capacity. For rasterization-focused tasks, the LX PRO holds the advantage in pixel rate and ROP count. Neither product has measured benchmark scores, so no practical workload comparison exists.

The production status for both is Active. The H800 was released on 2023-03-20; the LX PRO on 2026-03-16. The H800 lists a predecessor of Server Ada and a successor of Server Blackwell, while the LX PRO has no recorded predecessor or successor.

Without benchmark data, the choice depends on whether the workload requires the H800's massive memory and compute resources or the LX PRO's graphics output and rasterization hardware. The database provides no evidence that either product outperforms the other in real applications.
