Head-to-Head Benchmarks

The database contains no recorded head-to-head benchmark results for the NVIDIA H100 SXM5 96 GB versus the Lisuan Tech LX MAX. Both entries show an average benchmark score of zero and a percentile rank of 50 among all GPUs, which indicates that neither part has been exercised in the standardized test suite used by the database. Without measured scores, direct performance comparisons must rely on the hardware specifications and architectural characteristics recorded for each device.

The NVIDIA H100 SXM5 96 GB delivers a FP32 throughput of 66.91 TFLOPS, which is roughly 2.7 times the 24.58 TFLOPS of the Lisuan Tech LX MAX. For FP16 workloads, the H100 reaches 267.6 TFLOPS using a 4:1 ratio, while the LX MAX produces 49.15 TFLOPS at a 2:1 ratio. The H100's FP16 result is over five times higher, a gap that widens when considering the tensor core capabilities present in the H100 but entirely absent from the LX MAX specification.

Memory bandwidth separates the two by a wide margin. The H100 SXM5 uses HBM3 across a 5120-bit bus, achieving 3.36 TB/s. The LX MAX relies on GDDR6 over a 192-bit interface, reaching 432.0 GB/s. The H100's bandwidth is approximately 7.8 times greater, which directly impacts any memory-bound operation such as large matrix multiplications or data movement during model training.

Pixel throughput favors the LX MAX, which records 192.0 GPixel/s compared to 47.52 GPixel/s for the H100. Texture fill rate goes the other way, with the H100 producing 1,045.4 GTexel/s versus 384.0 GTexel/s for the LX MAX. The H100 also holds a large advantage in shading units, with 16,896 versus 6,144, and in tensor cores, where it has 528 units while the LX MAX lists none.

Clock speeds are partially recorded. The H100 runs at a base clock of 1350 MHz and boosts to 1980 MHz. The LX MAX has no base or boost clock listed, though its memory clock is set at 2250 MHz with 18 Gbps effective data rate. The H100 memory clock is 1313 MHz with 5.3 Gbps effective, so the LX MAX memory operates at a higher effective speed, but the HBM3 implementation on the H100 compensates through the vastly wider bus.

The H100 SXM5 is a server module with no display outputs, while the LX MAX is a dual-slot PCIe card with four DisplayPort 1.4a outputs. This difference alone dictates their primary use cases, as the LX MAX can drive displays while the H100 cannot.

Where Each One Wins

The NVIDIA H100 SXM5 96 GB dominates in raw compute throughput and memory bandwidth. Its FP32 result of 66.91 TFLOPS and FP16 result of 267.6 TFLOPS position it for heavy numerical workloads, particularly those that can exploit tensor cores. The 528 tensor cores provide hardware acceleration for matrix operations that the LX MAX cannot match. The H100's 3.36 TB/s memory bandwidth and 96 GB HBM3 capacity support large datasets that would not fit in the 12 GB GDDR6 memory of the LX MAX.

The Lisuan Tech LX MAX wins in pixel throughput, producing 192.0 GPixel/s against 47.52 GPixel/s for the H100. It also has a higher effective memory clock at 18 Gbps versus 5.3 Gbps, though the narrow 192-bit bus limits the practical benefit. The LX MAX includes four DisplayPort 1.4a outputs, making it suitable for direct display connection, which the H100 cannot do. The LX MAX also supports modern graphics APIs including DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.3, while the H100 lists no API support.

The H100 uses a PCIe 5.0 x16 interface, while the LX MAX uses PCIe 4.0 x16. The newer bus standard on the H100 provides higher transfer rates to the host system, which matters for data-intensive workloads. The LX MAX has a higher pixel rate and ROP count of 96 versus 24, suggesting stronger traditional rasterization capability, but the H100's texture rate of 1,045.4 GTexel/s far exceeds the LX MAX's 384.0 GTexel/s.

Specification Differences

The two GPUs differ across nearly every recorded specification. The NVIDIA H100 SXM5 uses the GH100 chip built on a 5 nm TSMC process with 80,000 million transistors on an 814 mm² die. The Lisuan Tech LX MAX uses the 7G106 chip on a 6 nm TSMC process with transistor count and die size listed as unknown.

Memory configuration shows a stark contrast. The H100 has 96 GB of HBM3 with a 5120-bit bus and 3.36 TB/s bandwidth. The LX MAX has 12 GB of GDDR6 with a 192-bit bus and 432.0 GB/s bandwidth. The H100 memory clock is 1313 MHz with 5.3 Gbps effective, while the LX MAX memory clock is 2250 MHz with 18 Gbps effective.

Compute resources differ significantly. The H100 contains 16,896 shading units, 528 TMUs, 24 ROPs, and 528 tensor cores. The LX MAX contains 6,144 shading units, 192 TMUs, 96 ROPs, and no tensor cores. The H100 produces 66.91 TFLOPS FP32 and 267.6 TFLOPS FP16 (4:1). The LX MAX produces 24.58 TFLOPS FP32 and 49.15 TFLOPS FP16 (2:1).

Power and physical specifications diverge as well. The H100 has a TDP of 700 W with an 8-pin EPS power connector and requires a suggested 1100 W PSU. The LX MAX has a TDP of 225 W with a single 16-pin connector and a suggested 550 W PSU. The H100 is an SXM module, while the LX MAX is a dual-slot card measuring 248 mm by 118 mm by 48 mm. The H100 uses PCIe 5.0 x16, and the LX MAX uses PCIe 4.0 x16. Display outputs: none for the H100, four DisplayPort 1.4a for the LX MAX.

Release dates also differ. The H100 launched on 2023-03-20, while the LX MAX has a listed release date of 2026-03-16. The H100's predecessor is listed as Server Ada and its successor as Server Blackwell. The LX MAX has no predecessor or successor recorded.

Architecture Differences

The NVIDIA H100 SXM5 is built on the Hopper architecture, specifically the GH100 chip, and belongs to the Server Hopper generation (Hxx). It uses a 5 nm process from TSMC with 80,000 million transistors packed into an 814 mm² die, yielding a transistor density of 98.3 million per square millimeter. The architecture includes 528 tensor cores, which are designed for accelerated deep learning and scientific computing. The H100 uses HBM3 memory in a 96 GB configuration, a choice that prioritizes bandwidth and capacity over clock speed.

The Lisuan Tech LX MAX uses the TrueGPU architecture with the 7G106 chip and belongs to the 7G100 generation. It is built on a 6 nm TSMC process, but transistor count and die size are unknown. The architecture includes no tensor cores. The LX MAX uses GDDR6 memory in a 12 GB configuration with a 192-bit bus. The 6 nm process is slightly less dense than the H100's 5 nm node, but the LX MAX has no recorded transistor density figure.

The H100's Hopper architecture supports FP16 at a 4:1 ratio, meaning the FP16 throughput is four times the FP32 rate. The LX MAX's TrueGPU supports FP16 at a 2:1 ratio, so its FP16 throughput is only double the FP32 rate. This architectural choice on the H100 indicates a stronger focus on reduced-precision workloads common in AI training and inference. The LX MAX's 2:1 ratio suggests a more balanced approach between precision levels.

The H100 has no display outputs and no API support recorded, confirming its role as a compute accelerator for servers. The LX MAX includes full graphics API support, including DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.3, along with four DisplayPort 1.4a outputs. The LX MAX also has a higher ROP count of 96 versus 24, which aligns with its graphics-oriented design. The H100's 24 ROPs are unusually low for its compute power, reinforcing that rasterization is not its purpose.

The Verdict

The NVIDIA H100 SXM5 96 GB is the clear choice for compute-heavy server workloads. Its FP32 performance of 66.91 TFLOPS and FP16 performance of 267.6 TFLOPS, combined with 528 tensor cores and 3.36 TB/s of memory bandwidth, make it suited for large-scale numerical processing. The 96 GB HBM3 capacity enables handling datasets that far exceed the 12 GB GDDR6 available on the LX MAX. The H100's 700 W TDP and SXM form factor require a server environment with appropriate power delivery, as indicated by the 1100 W suggested PSU.

The Lisuan Tech LX MAX serves a different purpose. Its 24.58 TFLOPS FP32 and 49.15 TFLOPS FP16 are respectable for a 225 W card, and its 192.0 GPixel/s pixel rate with 96 ROPs supports traditional graphics rendering. The four DisplayPort 1.4a outputs allow direct display connection, and the API support for DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.3 makes it a functional graphics card. The dual-slot 248 mm length fits standard PC cases, and the 550 W suggested PSU is far more modest than the H100's requirement.

The data shows that these GPUs are not direct competitors. The H100 targets datacenter acceleration with no display capability and a 700 W power envelope. The LX MAX targets workstation or desktop use with a 225 W power draw and full display connectivity. A user needing maximum compute throughput for AI or scientific workloads should select the H100. A user needing a graphics card with display outputs and modern API support should select the LX MAX. Benchmark results in the database are not available for either card, so the verdict relies entirely on the recorded specifications and architectural differences.
