NVIDIA H200 SXM 141 GB vs Lisuan Tech LX PRO Comparison

Head-to-Head Benchmarks

The recorded database contains no direct head-to-head benchmark runs for the NVIDIA H200 SXM 141 GB and the Lisuan Tech LX PRO. Both parts carry an identical percentile ranking against all GPUs in the database, sitting at the 50th percentile with an average benchmark score of zero. This means neither part has accumulated measured performance data from standardized workloads, so the comparison below relies entirely on the specification sheets and architectural parameters provided for each unit.

When the raw compute figures are placed side by side, the NVIDIA H200 SXM 141 GB delivers 66.91 TFLOPS of FP32 throughput against the Lisuan Tech LX PRO's 24.58 TFLOPS. That represents a 2.72x advantage for the H200 in single-precision work. In FP16 with the 2:1 ratio, the H200 produces 133.8 TFLOPS while the LX PRO produces 49.15 TFLOPS, a 2.72x margin as well. The texture rate follows the same pattern: the H200 reaches 1,045.4 GTexel/s versus 384.0 GTexel/s on the LX PRO, again a 2.72x gap. Pixel rate is the one metric where the LX PRO takes a clear lead, posting 192.0 GPixel/s against the H200's 47.52 GPixel/s, a 4.04x advantage for the Lisuan part.

Memory bandwidth is another decisive split. The H200 uses HBM3e across a 6144-bit bus to reach 4.89 TB/s, while the LX PRO uses GDDR6 on a 192-bit bus for 432.0 GB/s. That is an 11.3x difference in raw bandwidth. The memory capacity difference is equally stark: 141 GB on the H200 versus 24 GB on the LX PRO, a 5.88x gap. The LX PRO does counter with a higher effective memory clock of 18 Gbps against the H200's 6.4 Gbps effective, but the narrow bus width limits the practical impact of that faster signaling.

Neither part has recorded wins in any head-to-head benchmark category, and the winsA and winsB fields both read zero. The database therefore shows a specification-driven comparison rather than a measured performance contest. The H200 holds overwhelming advantages in compute throughput, memory bandwidth, and memory capacity. The LX PRO holds advantages in pixel fill rate, physical size, power draw, and display connectivity.

Where Each One Wins

The NVIDIA H200 SXM 141 GB is positioned for workloads that demand massive memory capacity and extreme bandwidth. Its 141 GB of HBM3e with 4.89 TB/s bandwidth suits large language model inference, scientific simulation, and data center-scale matrix operations. The 528 tensor cores on the GH100 chip provide dedicated hardware for mixed-precision neural network training and inference, and the 66.91 TFLOPS FP32 throughput supports general compute tasks that do not rely on tensor operations. The 5 nm TSMC process and 80,000 million transistor count on an 814 mm² die indicate a design optimized for raw throughput density rather than power efficiency. With a 700 W TDP and a suggested power supply rating of 1100 W, this part is intended for server racks with dedicated power delivery, not desktop systems.

The Lisuan Tech LX PRO is built for a different set of priorities. Its 24 GB of GDDR6 on a 192-bit bus delivers 432.0 GB/s, which is sufficient for 1080p and 1440p gaming workloads, video encoding, and general graphics acceleration. The 192.0 GPixel/s pixel rate, 2.72x higher than the H200, indicates strong rasterization throughput for traditional rendering pipelines. The 96 ROPs contribute to efficient pixel output, and the 4x DisplayPort 1.4a outputs make it a functional display adapter out of the box. The 225 W TDP with a 550 W suggested power supply allows installation in conventional desktop builds, and the 248 mm length, 118 mm height, and 48 mm width fit standard dual-slot chassis. The part supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.3, so modern game APIs are fully covered.

The architecture split is clear. The H200 wins on compute density, memory capacity, and bandwidth. The LX PRO wins on pixel throughput, display outputs, power efficiency, and physical compatibility. The H200 has no display outputs at all and does not expose DirectX, OpenGL, or Vulkan APIs, confirming it is a compute accelerator rather than a graphics card. The LX PRO is a conventional graphics card with full API support and display connectivity.

Architecture Differences

The two parts come from fundamentally different design lineages. The NVIDIA H200 SXM 141 GB uses the GH100 chip built on TSMC's 5 nm process, with the Hopper architecture and a transistor count of 80,000 million on an 814 mm² die. That yields a transistor density of 98.3 million transistors per square millimeter. The Lisuan Tech LX PRO uses the 7G105 chip on TSMC's 6 nm process, with the TrueGPU architecture and the 7G100 generation. Transistor count and die size for the LX PRO are not recorded in the database.

The H200 packs 16,896 shading units, 528 TMUs, 24 ROPs, and 528 tensor cores. The LX PRO has 6,144 shading units, 192 TMUs, and 96 ROPs, with no tensor cores listed. The H200 therefore has 2.75x the shading units and 2.75x the TMUs, but only one quarter of the ROPs. The tensor core count on the H200 gives it a dedicated path for AI workloads that the LX PRO lacks entirely.

Memory architecture differs completely. The H200 uses HBM3e with a 6144-bit bus and 1593 MHz memory clock, delivering 4.89 TB/s. The LX PRO uses GDDR6 with a 192-bit bus and 2250 MHz memory clock, delivering 432.0 GB/s. The HBM3e implementation trades higher latency for massive bandwidth and capacity, while GDDR6 offers lower cost and simpler integration at the expense of bandwidth.

The H200 uses a 700 W TDP with an 8-pin EPS power connector and an SXM Module slot width. The LX PRO uses a 225 W TDP with a single 16-pin connector and a dual-slot form factor. The bus interfaces also differ: the H200 runs PCIe 5.0 x16, while the LX PRO runs PCIe 4.0 x16.

The H200 has no display outputs and no graphics API support. The LX PRO has 4x DisplayPort 1.4a outputs and supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.3. The H200's release date is recorded as November 17, 2024, while the LX PRO's release date is March 16, 2026. The H200 lists Server Ada as its predecessor and Server Blackwell as its successor; the LX PRO lists neither.

The Verdict

The data points to two products with almost no overlap in intended use. The NVIDIA H200 SXM 141 GB is a server compute accelerator built for memory-bound and compute-heavy workloads. Its 141 GB of HBM3e, 4.89 TB/s bandwidth, 528 tensor cores, and 66.91 TFLOPS FP32 throughput make it suitable for large-scale AI training, inference, and scientific computing. The absence of display outputs and graphics API support confirms it is not a rendering device. The 700 W TDP, SXM Module form factor, and PCIe 5.0 interface all target rack-mounted server environments with dedicated power infrastructure.

The Lisuan Tech LX PRO is a conventional dual-slot graphics card for desktop systems. Its 24 GB GDDR6 memory, 192.0 GPixel/s pixel rate, 96 ROPs, and 4x DisplayPort 1.4a outputs position it for gaming, content creation, and general GPU-accelerated tasks that require a display connection. The DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.3 support covers modern graphics APIs. The 225 W TDP and 550 W suggested power supply fit standard desktop power envelopes, and the 248 mm length accommodates most mid-tower cases.

A user selecting between these parts should base the decision on workload type. Compute tasks that need massive memory capacity and bandwidth point to the H200. Graphics rendering, gaming, and any workflow requiring display output point to the LX PRO. The H200 has 2.72x the FP32 throughput and 11.3x the memory bandwidth, but the LX PRO has 4.04x the pixel rate and full display connectivity. These are not competing products in the same category; they are specialized tools for different jobs.
