NVIDIA H100 PCIe 96 GB vs Lisuan Tech LX PRO Comparison

NVIDIA H100 PCIe 96 GB and Lisuan Tech LX PRO represent two distinct approaches to GPU design, one optimized for massive compute throughput and high-bandwidth memory, the other for a balanced feature set with conventional graphics outputs. The database records no direct head-to-head benchmark scores for this pair, so the analysis below relies entirely on the recorded specifications, architectural data, and performance metrics for each part. The H100 PCIe 96 GB uses the GH100 chip on a 5 nm TSMC process, while the LX PRO uses the 7G105 chip on a 6 nm TSMC process. Both cards are currently active in production, with the H100 released in March 2023 and the LX PRO dated March 2026. Neither card has a launch MSRP recorded in the database.

Where Each One Wins

The H100 PCIe 96 GB dominates in raw compute density and memory bandwidth, making it the clear choice for workloads that stress FP32, FP16, and memory throughput. Its FP32 rating is 62.08 TFLOPS, which is 2.5 times the 24.58 TFLOPS of the LX PRO. In FP16, the H100 reaches 248.3 TFLOPS using a 4:1 ratio, while the LX PRO achieves 49.15 TFLOPS with a 2:1 ratio, a fivefold difference. The H100 also leads in texture rate with 969.9 GTexel/s versus 384.0 GTexel/s, and in memory bandwidth with 3.36 TB/s from HBM3 against 432.0 GB/s from GDDR6. For any task that scales with raw floating-point operations or memory movement, the H100 holds a decisive advantage.

The LX PRO wins in pixel fill rate, a metric tied to rasterization and display output. It records 192.0 GPixel/s, while the H100 manages only 44.09 GPixel/s, a 4.4 times advantage for the LX PRO. The LX PRO also carries four DisplayPort 1.4a outputs, whereas the H100 has no display outputs at all. This makes the LX PRO the only option for direct video output or graphics rendering to a screen. Additionally, the LX PRO supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.3, while the H100 lists no API support in the database. For graphics workloads, the LX PRO is the functional part; for compute, the H100 is the performance leader.

Architecture Differences

The H100 is built on the Hopper architecture, specifically the GH100 chip, and belongs to the Server Hopper generation. It uses a 5 nm process at TSMC, with 80,000 million transistors on a die size of 814 mm². The transistor density is 98.3 million per square millimeter. The LX PRO uses the TrueGPU architecture with the 7G105 chip, belongs to the 7G100 generation, and is fabricated on a 6 nm TSMC process. Its transistor count and die size are recorded as unknown, so no density figure is available. The process node difference suggests the H100 uses a more advanced lithography, but the LX PRO compensates with a smaller memory bus and different memory technology.

Memory architecture is a major split. The H100 uses 96 GB of HBM3 on a 5120-bit bus, yielding 3.36 TB/s bandwidth. The LX PRO uses 24 GB of GDDR6 on a 192-bit bus, yielding 432.0 GB/s. The H100’s bus width is over 26 times wider, and its bandwidth is 7.8 times higher. The H100’s memory clock is listed as 1313 MHz with 5.3 Gbps effective, while the LX PRO’s memory clock is 2250 MHz with 18 Gbps effective. The LX PRO’s memory runs faster per pin, but the H100’s vastly wider bus delivers far more total throughput.

Compute resources differ sharply. The H100 has 16,896 shading units, 528 TMUs, and 24 ROPs, with 528 tensor cores. The LX PRO has 6,144 shading units, 192 TMUs, and 96 ROPs, with no tensor cores recorded. The H100 has 2.75 times the shading units and TMUs, but the LX PRO has 4 times the ROPs. This explains the H100’s higher texture rate and the LX PRO’s higher pixel rate. The H100’s 528 tensor cores are absent from the LX PRO, indicating a design focus on AI and matrix math for the H100.

Power and connectivity also differ. The H100 has a TDP of 700 W, uses an 8-pin EPS connector, and recommends a 1100 W PSU. The LX PRO has a TDP of 225 W, uses a single 16-pin connector, and recommends a 550 W PSU. The H100 uses PCIe 5.0 x16, while the LX PRO uses PCIe 4.0 x16. The H100 is a dual-slot card measuring 268 mm in length and 111 mm in height. The LX PRO is also dual-slot, measuring 248 mm in length, 118 mm in height, and 48 mm in width. The H100 has no display outputs; the LX PRO has four DisplayPort 1.4a outputs.

Head-to-Head Benchmarks

The database contains no recorded head-to-head benchmark scores for these two GPUs, and neither card has any individual benchmark entries. The wins and losses are therefore calculated from the specification-derived metrics, which serve as the only quantitative basis for comparison. Using those metrics, the H100 wins in FP32, FP16, texture rate, memory bandwidth, and memory capacity. The LX PRO wins in pixel rate, memory clock, and API support.

FP32 performance is 62.08 TFLOPS for the H100 against 24.58 TFLOPS for the LX PRO. This is a 2.53 times advantage for the H100, meaning the H100 can process 2.5 times as many single-precision floating-point operations per second. For scientific simulation, physics calculations, or general compute, this is the primary figure. The H100’s lead in FP16 is even larger: 248.3 TFLOPS versus 49.15 TFLOPS, a 5.05 times difference. The LX PRO’s FP16 rate uses a 2:1 ratio, while the H100 uses a 4:1 ratio, indicating the H100 is optimized for half-precision workloads like deep learning training and inference.

Texture rate follows the shading unit count. The H100 achieves 969.9 GTexel/s from 528 TMUs, while the LX PRO achieves 384.0 GTexel/s from 192 TMUs. This is a 2.53 times advantage, matching the FP32 ratio exactly, since both derive from the same clock and unit counts. The H100’s pixel rate, however, is far lower at 44.09 GPixel/s from 24 ROPs, against 192.0 GPixel/s from 96 ROPs for the LX PRO. The LX PRO’s pixel rate is 4.35 times higher, a direct result of having 4 times the ROPs and a higher memory clock.

Memory bandwidth is the most lopsided metric. The H100’s 3.36 TB/s is 7.78 times the LX PRO’s 432.0 GB/s. This bandwidth advantage is critical for large datasets, high-resolution tensors, or any workload that streams data through the GPU. The H100’s 96 GB capacity is 4 times the LX PRO’s 24 GB, allowing the H100 to hold entire models or datasets in memory without spilling to system RAM. The LX PRO’s memory clock is higher at 2250 MHz versus 1313 MHz, but the HBM3 interface on the H100 more than compensates with its 5120-bit bus.

The Verdict

The data points to a clear separation of roles. For compute-intensive tasks, the NVIDIA H100 PCIe 96 GB is the stronger part. Its FP32 and FP16 ratings are 2.53 and 5.05 times the LX PRO’s, respectively. Its memory bandwidth is 7.78 times higher, and its 96 GB capacity is 4 times larger. The presence of 528 tensor cores further reinforces its suitability for AI and matrix workloads. The 700 W TDP and 1100 W PSU recommendation reflect the cost of that performance, and the lack of display outputs means it is designed for server environments where video output is handled elsewhere.

For graphics rendering or any scenario requiring direct display output, the Lisuan Tech LX PRO is the only viable option. It provides four DisplayPort 1.4a connections and supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.3, which the H100 does not. Its pixel rate of 192.0 GPixel/s is 4.35 times the H100’s, making it better suited for rasterization-heavy work. The LX PRO also uses far less power at 225 W, and its PCIe 4.0 interface is older but still functional for most graphics workloads.

The H100 wins in every metric related to raw compute throughput and memory bandwidth. The LX PRO wins in every metric related to pixel output, API compatibility, and display functionality. There is no single winner across all categories. The choice depends entirely on the intended use case, and the recorded data supports a definitive split: compute servers and AI training favor the H100, while graphics workstations and display-driven tasks favor the LX PRO. The absence of shared benchmark scores means these specification-derived ratios are the only quantitative comparison available, but they are consistent across multiple independent metrics.
