NVIDIA H800 SXM5 vs Lisuan Tech LX 7G100 Comparison

Head-to-Head Benchmarks

The database records no direct head-to-head benchmark results for the NVIDIA H800 SXM5 and the Lisuan Tech LX 7G100. Both entries show an average benchmark score of 0 and a percentile rank of 50 among all GPUs, with no nearest rivals listed. This means the comparative analysis must rely entirely on the recorded specification data rather than measured performance outcomes.

What the data does show is a significant split in raw compute capabilities. The NVIDIA H800 SXM5 delivers 59.30 TFLOPS of FP32 performance, which is 2.4 times the 24.58 TFLOPS recorded for the Lisuan Tech LX 7G100. In FP16, the H800 reaches 237.2 TFLOPS (4:1 ratio), while the LX 7G100 manages 49.15 TFLOPS (2:1 ratio). The H800 holds a 4.8 to 1 advantage in half-precision throughput when accounting for the respective ratios.

Pixel processing tells the opposite story. The LX 7G100 achieves 192.0 GPixel/s, which is 4.6 times the 42.12 GPixel/s of the H800. Texture fill rates are closer: the H800 posts 926.6 GTexel/s against 384.0 GTexel/s for the LX 7G100, giving NVIDIA a 2.4 to 1 lead.

Memory bandwidth heavily favors the H800. The SXM5 module provides 3.36 TB/s over a 5120-bit HBM3 interface, compared to 432.0 GB/s across a 192-bit GDDR6 bus for the LX 7G100. That is a 7.8 to 1 difference. However, the LX 7G100 uses faster effective memory signaling at 18 Gbps versus 5.3 Gbps on the H800, though the H800 compensates with its vastly wider bus.

Architecture Differences

The two products sit on different manufacturing nodes and design philosophies. NVIDIA's H800 SXM5 uses the GH100 chip built on a 5 nm process at TSMC, with 80,000 million transistors on an 814 mm² die. That translates to a transistor density of 98.3 million per square millimeter. The architecture is Hopper, part of the Server Hopper (Hxx) generation. The Lisuan Tech LX 7G100 uses the 7G106 chip on a 6 nm process, also from TSMC, but the database lists transistor count and die size as unknown.

The H800 employs 16,896 shading units, 528 TMUs, and 24 ROPs. It packs 528 tensor cores, which the LX 7G100 lacks entirely. The LX 7G100 has 6,144 shading units, 192 TMUs, and 96 ROPs. The ROP count is 4 times higher on the Lisuan part, which explains its pixel rate advantage. The H800 has no display outputs, while the LX 7G100 provides 4x DisplayPort 1.4a outputs.

API support differs completely. The LX 7G100 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.3. The H800 lists null values for DirectX, OpenGL, and Vulkan, consistent with its server accelerator role. Memory configurations also diverge: 80 GB HBM3 on the H800 versus 12 GB GDDR6 on the LX 7G100.

Power and physical design separate the two further. The H800 is an SXM module with a 700 W TDP and requires an 8-pin EPS connector plus a suggested 1100 W power supply. The LX 7G100 is a dual-slot card at 225 W TDP, uses a single 8-pin connector, and suggests a 550 W PSU. The LX 7G100 measures 294 mm in length, 120 mm in height, and 49 mm in width. The H800 has no recorded dimensions. The H800 uses PCIe 5.0 x16, while the LX 7G100 uses PCIe 4.0 x16.

The H800's release date is March 2023, with a predecessor listed as Server Ada and a successor as Server Blackwell. The LX 7G100 has a release date of June 2026 and no recorded predecessor or successor. Both are marked as Active production status.

Where Each One Wins

The NVIDIA H800 SXM5 wins decisively in compute-heavy workloads that rely on FP32, FP16, and tensor operations. Its 59.30 TFLOPS FP32 and 237.2 TFLOPS FP16 figures, combined with 528 tensor cores, position it for large-scale matrix mathematics, neural network training, and scientific simulation. The 3.36 TB/s memory bandwidth and 80 GB HBM3 capacity allow it to feed data to those cores at a rate the LX 7G100 cannot match. The 2.4 to 1 lead in texture rate also favors the H800 for tasks that sample textures heavily.

The Lisuan Tech LX 7G100 wins in pixel throughput and graphics output. Its 192.0 GPixel/s is 4.6 times the H800's rate, and its 96 ROPs quadruple the H800's 24. The 4x DisplayPort 1.4a outputs make it a display-capable device, while the H800 has no outputs at all. The LX 7G100 also supports modern graphics APIs, whereas the H800 has no recorded API support. For rasterization, frame composition, or any workload that ends with pixels on a screen, the LX 7G100 is the only viable option in this pairing.

Memory speed per pin favors the LX 7G100. Its 18 Gbps effective GDDR6 signaling is 3.4 times faster than the H800's 5.3 Gbps effective HBM3 signaling. That advantage disappears when total bandwidth is considered, but for latency-sensitive or small-footprint workloads, the faster per-pin rate may matter.

The Verdict

The database presents two products with no overlapping use case. The NVIDIA H800 SXM5 is a server accelerator built for raw computation. Its 59.30 TFLOPS FP32, 237.2 TFLOPS FP16, 528 tensor cores, 80 GB HBM3, and 3.36 TB/s bandwidth indicate a device designed for large-scale numerical workloads. The lack of display outputs and API support confirms it is not meant for graphics presentation. The 700 W TDP and SXM module form factor further signal a data-center installation.

The Lisuan Tech LX 7G100 is a graphics card. Its 192.0 GPixel/s pixel rate, 96 ROPs, 4x DisplayPort 1.4a outputs, and full API support (DirectX 12 Ultimate, OpenGL 4.6, Vulkan 1.3) make it suitable for rendering to a screen. The 12 GB GDDR6 and 432.0 GB/s bandwidth provide enough memory throughput for display workloads, and the 225 W TDP with a dual-slot design allows standard PC installation.

The data does not support choosing one over the other for the same task. For compute density, tensor operations, or high-bandwidth data movement, the H800 is superior by factors of 2.4 to 7.8 in the relevant metrics. For pixel generation, graphics API compatibility, or display output, the LX 7G100 is the only option. The H800's 4.8 to 1 FP16 advantage and 2.4 to 1 texture rate lead suggest it dominates any non-graphics workload. The LX 7G100's 4.6 to 1 pixel rate advantage and 4 to 1 ROP lead make it the clear choice for rasterization. Buyers should match the hardware to the workload: H800 for compute servers, LX 7G100 for graphics workstations.
