Architecture Differences

The NVIDIA H100 CNX and the Lisuan Tech LX MAX represent fundamentally different design philosophies. The H100 CNX is built on the Hopper architecture, a dedicated server-grade compute platform from NVIDIA. It uses the GH100 chip fabricated on a 5 nm process at TSMC. The transistor count is listed at 80,000 million, packed into a die size of 814 mm², yielding a transistor density of 98.3M per mm². This is a massive, high-bandwidth compute engine aimed at data center workloads.

The Lisuan Tech LX MAX, by contrast, uses the TrueGPU architecture with a 7G106 chip, manufactured on a 6 nm process, also at TSMC. The database does not list its transistor count or die size. The LX MAX includes display outputs (4x DisplayPort 1.4a) and supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.3, indicating a client-oriented or workstation-oriented design. The H100 CNX has no display outputs and no listed API support, consistent with a headless accelerator.

Memory architecture differs substantially. The H100 CNX uses 80 GB of HBM2e across a 5120-bit bus, delivering 2.04 TB/s of bandwidth. The LX MAX uses 12 GB of GDDR6 on a 192-bit bus, yielding 432.0 GB/s. The H100 CNX has 456 tensor cores, while the LX MAX lists no tensor cores. The H100 CNX also has a higher transistor density, reflecting its more complex compute structure.

Clock behavior also distinguishes the two. The H100 CNX has a base clock of 690 MHz and a boost clock of 1845 MHz. The LX MAX has no base or boost clocks listed, but its memory runs at 2250 MHz with 18 Gbps effective. The H100 CNX memory runs at 1593 MHz with 3.2 Gbps effective.

Power delivery differs: the H100 CNX uses an 8-pin EPS connector and has a TDP of 350 W, while the LX MAX uses a single 16-pin connector and a TDP of 225 W. The H100 CNX suggests a 750 W power supply; the LX MAX suggests 550 W. Physically, the H100 CNX is 267 mm long and 111 mm tall, while the LX MAX is 248 mm long, 118 mm tall, and 48 mm wide.

The Verdict

The recorded data shows two accelerators targeting different segments. The NVIDIA H100 CNX is a server-class compute card with an 80 GB HBM2e memory pool, 2.04 TB/s bandwidth, and 456 tensor cores. Its FP32 throughput is 53.84 TFLOPS and FP16 is 215.4 TFLOPS (4:1). It has no display outputs and is built for compute-heavy environments.

The Lisuan Tech LX MAX is a smaller, lower-power card with 12 GB GDDR6, 432.0 GB/s bandwidth, and no tensor cores. Its FP32 throughput is 24.58 TFLOPS and FP16 is 49.15 TFLOPS (2:1). It has four DisplayPort outputs and full DirectX 12 Ultimate support.

Based on the database, the H100 CNX is the choice for workloads that demand large memory capacity, high memory bandwidth, and tensor core acceleration. The LX MAX fits scenarios where display output, a lower power envelope, and a smaller physical footprint are required. Neither card has benchmark scores recorded, and both hold a percentile rank of 50 among all GPUs, with an average benchmark score of 0. The launch MSRP is not listed for either card.

Head-to-Head Benchmarks

The database records no head-to-head benchmark entries and no wins for either card. Both cards have an average benchmark score of 0 and a percentile rank of 50. Therefore, direct performance comparisons rely on computed specifications rather than measured results.

In raw FP32 compute, the NVIDIA H100 CNX delivers 53.84 TFLOPS, which is more than double the 24.58 TFLOPS of the Lisuan Tech LX MAX. The FP16 comparison shows a larger gap: the H100 CNX produces 215.4 TFLOPS (4:1) versus 49.15 TFLOPS (2:1) for the LX MAX. That is a substantial difference in peak throughput for mixed-precision workloads.

Memory bandwidth favors the H100 CNX decisively. With 2.04 TB/s, it offers nearly five times the bandwidth of the LX MAX, which sits at 432.0 GB/s. The H100 CNX also has 80 GB of memory versus 12 GB, a 6.7x capacity advantage. These figures indicate the H100 CNX is designed for data sets that exceed the memory capacity of most client GPUs.

Pixel rate is one area where the LX MAX leads. It produces 192.0 GPixel/s, compared to 44.28 GPixel/s for the H100 CNX. The LX MAX also has more ROPs (96 versus 24). Texture rate, however, favors the H100 CNX at 841.3 GTexel/s versus 384.0 GTexel/s, driven by its higher TMU count (456 versus 192).

The H100 CNX has 14,592 shading units, more than double the 6,144 on the LX MAX. The transistor count difference is similarly lopsided: 80,000 million for the H100 CNX versus unknown for the LX MAX. The die size of 814 mm² for the H100 CNX reflects a much larger physical implementation.

The LX MAX counters with a higher pixel throughput and a lower power draw of 225 W versus 350 W. Its memory clock runs at 2250 MHz with 18 Gbps effective, while the H100 CNX memory runs at 1593 MHz with 3.2 Gbps effective. The LX MAX also supports PCIe 4.0 x16, whereas the H100 CNX uses PCIe 5.0 x16.

The data shows that the H100 CNX dominates in compute throughput, memory capacity, memory bandwidth, texture rate, and shading unit count. The LX MAX leads in pixel rate, ROP count, and has a smaller power footprint. Without recorded benchmark scores, these specification differences define the performance envelope of each card.
