NVIDIA H100 SXM5 96 GB vs Lisuan Tech LX PRO Comparison

The Verdict

The recorded data separates these two server accelerators into distinct performance and deployment classes. The NVIDIA H100 SXM5 96 GB occupies the high-capacity, high-throughput segment of the database, while the Lisuan Tech LX PRO targets a lower-power, compact form factor with a different feature set.

The H100 SXM5 96 GB delivers significantly higher raw compute throughput across both FP32 and FP16 workloads. Its FP32 rate of 66.91 TFLOPS is roughly 2.7 times the LX PRO's 24.58 TFLOPS. In FP16, the H100 reaches 267.6 TFLOPS using a 4:1 ratio, versus the LX PRO's 49.15 TFLOPS at 2:1. For any workload that depends on dense floating-point arithmetic, the H100 is the stronger choice.

The Lisuan Tech LX PRO counters with a substantially lower power envelope (225 W TDP versus 700 W), a dual-slot PCIe 4.0 x16 card format, and four DisplayPort 1.4a outputs. The H100 SXM5 has no display outputs and uses an SXM module form factor with an 8-pin EPS connector. The LX PRO is the only one of the two that can drive displays directly.

For memory capacity and bandwidth, the H100 leads decisively. It provides 96 GB of HBM3 across a 5120-bit bus, achieving 3.36 TB/s. The LX PRO provides 24 GB of GDDR6 across a 192-bit bus, delivering 432.0 GB/s. The H100's memory bandwidth is roughly 7.8 times higher.

The data indicates the H100 targets training and inference workloads that require massive memory capacity and bandwidth, while the LX PRO suits applications needing moderate compute, lower power, and direct display output. Users with FP32-heavy or FP16-heavy workloads should choose the H100. Users constrained by power budgets or requiring display outputs should choose the LX PRO.

Architecture Differences

The two accelerators use different process nodes, chip designs, and memory technologies. The NVIDIA H100 SXM5 96 GB uses the GH100 chip built on the Hopper architecture. The manufacturing process is 5 nm at TSMC, with 80,000 million transistors on an 814 mm² die. The transistor density measures 98.3 million transistors per square millimeter.

The Lisuan Tech LX PRO uses the 7G105 chip built on the TrueGPU architecture. TSMC fabricates this chip on a 6 nm process. The database lists transistor count and die size as unknown, and no transistor density figure is recorded.

The H100 integrates 16,896 shading units, 528 texture mapping units, and 24 raster operation units. It also includes 528 tensor cores. The LX PRO integrates 6,144 shading units, 192 TMUs, and 96 ROPs. The LX PRO has no tensor cores listed in the database.

Memory architecture differs completely. The H100 uses HBM3 with a 5120-bit bus width, delivering 3.36 TB/s of bandwidth. The LX PRO uses GDDR6 with a 192-bit bus, delivering 432.0 GB/s. The H100's memory clock is listed as 1313 MHz with 5.3 Gbps effective throughput, while the LX PRO's memory clock is 2250 MHz with 18 Gbps effective throughput.

The H100's clock speeds are recorded as 1350 MHz base and 1980 MHz boost. The LX PRO has no base or boost clock figures in the database. The H100's pixel rate is 47.52 GPixel/s and its texture rate is 1,045.4 GTexel/s. The LX PRO posts a pixel rate of 192.0 GPixel/s and a texture rate of 384.0 GTexel/s.

The H100 uses an SXM module slot width and requires an 8-pin EPS power connector. The suggested PSU rating is 1100 W. The LX PRO is a dual-slot card using a single 16-pin connector, with a suggested PSU of 550 W.

Interface support also differs. The H100 uses PCIe 5.0 x16, while the LX PRO uses PCIe 4.0 x16. The H100 has no display outputs. The LX PRO provides four DisplayPort 1.4a outputs and supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.3. The H100 lists no API support in the database.

Where Each One Wins

The H100 SXM5 96 GB wins in raw compute throughput. Its FP32 performance of 66.91 TFLOPS exceeds the LX PRO's 24.58 TFLOPS by a factor of roughly 2.7. Its FP16 performance of 267.6 TFLOPS (4:1) exceeds the LX PRO's 49.15 TFLOPS (2:1) by a factor of approximately 5.4.

The H100 also wins on memory capacity and bandwidth. It holds 96 GB versus 24 GB, a 4x capacity advantage. Its 3.36 TB/s bandwidth is roughly 7.8 times the LX PRO's 432.0 GB/s. The H100's 5120-bit bus width is over 26 times wider than the LX PRO's 192-bit bus.

The H100 wins on texture throughput. Its 1,045.4 GTexel/s exceeds the LX PRO's 384.0 GTexel/s by a factor of 2.7. The H100 also includes tensor cores (528), a feature entirely absent from the LX PRO's specification sheet.

The LX PRO wins on pixel throughput. Its 192.0 GPixel/s exceeds the H100's 47.52 GPixel/s by a factor of 4.0. This advantage comes from the LX PRO's higher ROP count (96 versus 24) and its different rendering pipeline.

The LX PRO wins on power efficiency in terms of TDP. It draws 225 W versus the H100's 700 W, roughly one-third the power. The suggested PSU requirement reflects this: 550 W for the LX PRO versus 1100 W for the H100.

The LX PRO wins on physical integration flexibility. It is a dual-slot PCIe card measuring 248 mm in length, 118 mm in height, and 48 mm in width. It connects via PCIe 4.0 x16 and provides four DisplayPort 1.4a outputs. The H100 is an SXM module with no display outputs.

The LX PRO wins on API compatibility. It supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.3. The H100 lists no API support in the database, which aligns with its server-oriented role and lack of display outputs.

The H100 wins on interface bandwidth potential. It uses PCIe 5.0 x16, while the LX PRO uses PCIe 4.0 x16. The H100 also has a higher transistor count (80,000 million) compared to the LX PRO's unknown count.

Head-to-Head Benchmarks

The database records no direct head-to-head benchmark results between these two accelerators, and both have zero wins in the comparison fields. The analysis below relies on the specification-level performance metrics recorded in the database.

The largest single-metric advantage for the H100 appears in memory bandwidth. The H100's 3.36 TB/s versus the LX PRO's 432.0 GB/s represents a 7.8x gap. For workloads that stream large datasets, such as training sets that exceed local cache, this difference directly impacts throughput.

The FP16 comparison shows the second-largest gap. The H100's 267.6 TFLOPS (4:1) versus the LX PRO's 49.15 TFLOPS (2:1) yields a 5.4x difference. This matters for machine learning training loops that rely on reduced precision arithmetic. The H100's tensor cores (528) provide dedicated hardware for such operations, a resource the LX PRO entirely lacks.

The FP32 comparison shows a 2.7x gap. The H100's 66.91 TFLOPS versus the LX PRO's 24.58 TFLOPS reflects the H100's higher shading unit count (16,896 versus 6,144) and its higher boost clock (1980 MHz versus no recorded boost clock). For scientific computing or graphics workloads using single-precision math, this gap is substantial.

Texture throughput shows the same 2.7x ratio. The H100's 1,045.4 GTexel/s versus the LX PRO's 384.0 GTexel/s follows from the H100's larger TMU count (528 versus 192). Applications that sample textures heavily, such as real-time rendering or image processing pipelines, will see a proportional difference.

The LX PRO's largest advantage appears in pixel throughput. Its 192.0 GPixel/s versus the H100's 47.52 GPixel/s represents a 4.0x difference. This stems from the LX PRO's higher ROP count (96 versus 24). Rasterization-heavy workloads, including frame buffer operations and pixel shading, favor the LX PRO.

Memory capacity shows a 4x advantage for the H100. With 96 GB versus 24 GB, the H100 can hold larger models, larger batch sizes, or larger working sets entirely on the accelerator. The LX PRO's 24 GB may require more frequent data movement between the card and host memory.

The power envelope shows the LX PRO at 225 W versus the H100 at 700 W. The LX PRO draws 32.1% of the H100's power budget. This allows the LX PRO to fit into systems with a 550 W suggested PSU, while the H100 requires an 1100 W suggested PSU.

The physical form factor favors the LX PRO for integration into standard server chassis. It is a dual-slot card with dimensions of 248 mm length, 118 mm height, and 48 mm width. The H100 uses an SXM module, which requires a compatible server board and chassis. The LX PRO's PCIe 4.0 x16 interface allows installation into a wider range of existing systems, while the H100's PCIe 5.0 x16 interface offers higher host interconnect bandwidth for newer platforms.
