NVIDIA H100 SXM5 64 GB vs Lisuan Tech LX MAX Comparison

Head-to-Head Benchmarks

The database contains no recorded head-to-head benchmark results for the NVIDIA H100 SXM5 64 GB versus the Lisuan Tech LX MAX. Both entries show zero benchmark scores, zero average benchmark scores, and zero wins in the head-to-head comparison table. The percentile versus all GPUs field is identical for both, at 50, which indicates the database places each product at the median of its respective performance distribution, though neither has any measured data to substantiate that placement.

Without direct comparative scores, the only quantitative comparison available comes from the specification-level computed rates. The NVIDIA H100 SXM5 64 GB delivers 66.91 TFLOPS of FP32 compute, while the Lisuan Tech LX MAX delivers 24.58 TFLOPS. That places the H100 at approximately 2.7 times the FP32 throughput of the LX MAX. In FP16, the H100 lists 267.6 TFLOPS under a 4:1 ratio, whereas the LX MAX lists 49.15 TFLOPS under a 2:1 ratio, a gap of roughly 5.4 times in favor of the H100. The pixel rate favors the LX MAX, however: 192.0 GPixel/s against 47.52 GPixel/s for the H100, a 4.0 times advantage. The texture rate favors the H100 at 1,045.4 GTexel/s versus 384.0 GTexel/s, a 2.7 times margin.

Memory bandwidth heavily favors the H100, which records 2.02 TB/s from HBM3 across a 3072-bit bus. The LX MAX records 432.0 GB/s from GDDR6 across a 192-bit bus. That is a 4.7 times bandwidth advantage for the H100. The H100 also has substantially more memory capacity at 64 GB versus 12 GB. The LX MAX counters with a higher pixel fill rate, which suggests its ROP configuration (96 ROPs versus 24 ROPs) is optimized for rasterization throughput rather than compute density.

Where Each One Wins

The H100 SXM5 wins in compute throughput, memory capacity, memory bandwidth, texture rate, and transistor count. Its FP32 figure of 66.91 TFLOPS and FP16 figure of 267.6 TFLOPS position it as a data-center compute device. The 64 GB HBM3 pool with 2.02 TB/s bandwidth supports large model weights and high-bandwidth access patterns. The texture rate of 1,045.4 GTexel/s, driven by 528 TMUs, indicates strong texel processing capability.

The Lisuan Tech LX MAX wins in pixel throughput, ROP count, and display output support. Its 192.0 GPixel/s pixel rate is 4.0 times the H100's 47.52 GPixel/s, and its 96 ROPs are 4.0 times the H100's 24 ROPs. The LX MAX also supports four DisplayPort 1.4a outputs, while the H100 has no display outputs. The LX MAX's 12 GB GDDR6 memory, while smaller, runs at 18 Gbps effective, which is higher than the H100's 5.3 Gbps effective memory clock, though the HBM3 implementation on the H100 achieves far higher aggregate bandwidth.

The LX MAX also wins on physical integration: it is a dual-slot card measuring 248 mm by 118 mm by 48 mm, uses a single 16-pin power connector, and requires a 550 W suggested PSU. The H100 is an SXM module, uses an 8-pin EPS power connector, and requires a 1100 W suggested PSU. The LX MAX's 225 W TDP is far lower than the H100's 700 W TDP, which indicates the LX MAX is designed for air-cooled workstation or server environments, while the H100 targets liquid-cooled or high-density data-center racks.

Architecture Differences

The H100 uses the GH100 chip built on the Hopper architecture, fabricated by TSMC on a 5 nm process. The LX MAX uses the 7G106 chip built on the TrueGPU architecture, also fabricated by TSMC but on a 6 nm process. The H100 integrates 80,000 million transistors on an 814 mm² die, yielding a transistor density of 98.3 million per square millimeter. The LX MAX's transistor count and die size are unknown in the database, so no density comparison is possible.

The H100 belongs to the Server Hopper generation, while the LX MAX belongs to the 7G100 generation. The H100's predecessor is listed as Server Ada and its successor as Server Blackwell, indicating a defined product roadmap. The LX MAX has no listed predecessor or successor, suggesting a standalone or first-generation product.

The H100 includes 528 tensor cores, the LX MAX lists none. The H100's shading unit count is 16,896, the LX MAX has 6,144. The H100 has 528 TMUs, the LX MAX has 192. The H100 has 24 ROPs, the LX MAX has 96. The H100 has no RT cores listed, and the LX MAX also has none listed.

The H100's FP16 compute is listed at a 4:1 ratio, meaning the 267.6 TFLOPS figure is achieved with four FP16 operations per clock per lane. The LX MAX's FP16 is listed at a 2:1 ratio, achieving 49.15 TFLOPS. The H100's FP32 figure of 66.91 TFLOPS is the standard single-precision rate. The LX MAX's FP32 figure of 24.58 TFLOPS is also standard. The H100's compute-to-bandwidth ratio is approximately 33.1 TFLOPS per TB/s of memory bandwidth, while the LX MAX's ratio is approximately 56.9 TFLOPS per TB/s, indicating the LX MAX has a tighter balance between compute and memory throughput.

The Verdict

The data indicates two fundamentally different product categories. The NVIDIA H100 SXM5 64 GB is a data-center compute accelerator. Its 64 GB HBM3 pool, 2.02 TB/s bandwidth, 16,896 shading units, 528 tensor cores, and 66.91 TFLOPS FP32 place it squarely in high-performance computing and AI training workloads. The absence of display outputs confirms its role as a server module, not a workstation graphics card.

The Lisuan Tech LX MAX is a workstation or consumer-oriented GPU. Its 4x DisplayPort 1.4a outputs, DirectX 12 Ultimate support, OpenGL 4.6, Vulkan 1.3, dual-slot form factor, and 225 W TDP indicate a rasterization-focused product. The 192.0 GPixel/s pixel rate and 96 ROPs give it a clear advantage in fill-rate-bound workloads. The 12 GB GDDR6 memory and 432.0 GB/s bandwidth are sufficient for typical graphics workloads but far below the H100's capacity.

The H100 wins on compute density, memory capacity, and memory bandwidth. The LX MAX wins on pixel throughput, display connectivity, and power efficiency. The H100's FP16 advantage is particularly large at 267.6 TFLOPS versus 49.15 TFLOPS, which matters for mixed-precision training. The LX MAX has no tensor cores listed, so its FP16 path relies on standard shader execution.

The bus interface difference (PCIe 5.0 x16 versus PCIe 4.0 x16) gives the H100 a potential data-transfer advantage, though the LX MAX's smaller memory footprint may reduce the need for host transfers. The process node difference (5 nm versus 6 nm) is minor, and both are TSMC fabricated.

The H100's 80,000 million transistors on 814 mm² indicate a much larger and more complex chip than the LX MAX, whose transistor count and die size are unknown. The H100's 528 TMUs versus the LX MAX's 192 TMUs explain its 2.7 times texture rate advantage. The LX MAX's 96 ROPs versus the H100's 24 ROPs explain its 4.0 times pixel rate advantage.

For compute-heavy workloads such as large-scale training, inference, scientific simulation, or any task requiring large memory capacity and high bandwidth, the H100 is the clear choice. For graphics rendering, display output, or fill-rate-bound applications, the LX MAX is the only option with display support, and its pixel throughput is superior. The H100's 700 W TDP and 1100 W suggested PSU require infrastructure that the LX MAX's 225 W TDP and 550 W suggested PSU do not.

The release dates show the H100 launched in 2023, while the LX MAX is dated 2026, indicating a newer product. Both are listed as Active in production. The database currently has no benchmark scores for either, so the percentile of 50 for both is provisional. The specification-level analysis above is the only quantitative basis for comparison until measured results are recorded.
