Architecture Differences

The NVIDIA RTX 4000 SFF Ada Generation uses the AD104 chip built on TSMC's 5 nm process, with 35,800 million transistors on a 294 mm² die. This yields a transistor density of 121.8 million per mm². The architecture is Ada Lovelace, part of the GeForce 40-series, and its generation is listed as Workstation Ada. The LX MAX uses the 7G106 chip on TSMC's 6 nm process, with the TrueGPU architecture and the 7G100 generation. Transistor count and die size are unknown for the LX MAX.

Both cards use GDDR6 memory, but the RTX 4000 SFF Ada Generation runs its memory at 1750 MHz with 14 Gbps effective speed, while the LX MAX runs at 2250 MHz with 18 Gbps effective speed. The RTX 4000 SFF Ada Generation has 6144 shading units and 192 texture mapping units, matching the LX MAX's 6144 shading units and 192 TMUs. The LX MAX has 96 ROPs versus 64, and the RTX 4000 SFF Ada Generation includes 48 RT cores and 192 tensor cores, which the LX MAX does not list.

API support shows the RTX 4000 SFF Ada Generation supports Vulkan 1.4, while the LX MAX supports Vulkan 1.3. Both support DirectX 12 Ultimate (12_2) and OpenGL 4.6. Display outputs differ: the RTX 4000 SFF Ada Generation has four mini-DisplayPort 1.4a connectors, while the LX MAX has four full-size DisplayPort 1.4a connectors. The bus interface is PCIe 4.0 x16 for both.

The RTX 4000 SFF Ada Generation was released on March 20, 2023, while the LX MAX has a release date of March 16, 2026.

The Verdict

The data indicates two distinctly positioned products. The NVIDIA RTX 4000 SFF Ada Generation is a compact, low-power workstation card with verified benchmark results. Its 95th percentile ranking and average score of 117,088 place it competitively against the NVIDIA GB10, AMD Radeon PRO W7700, NVIDIA Tesla V100 SXM2 16 GB, and NVIDIA RTX A5500 Mobile. Its 20 GB memory capacity, 48 RT cores, and 192 tensor cores support workloads involving ray tracing and AI acceleration. Its 70 W TDP and 168 mm length make it suitable for space-constrained systems.

The Lisuan Tech LX MAX lacks any benchmark scores, leaving its real-world performance unverified. Its specifications suggest a higher theoretical compute ceiling with 24.58 TFLOPS FP32, 432.0 GB/s bandwidth, and 96 ROPs. However, the 12 GB memory capacity and 225 W power draw present trade-offs. The absence of RT core and tensor core data indicates potential limitations for ray-traced or tensor-based tasks.

Users requiring a compact card with proven performance, large memory, and specialized AI/RT hardware should consider the RTX 4000 SFF Ada Generation. Users prioritizing raw fill rates and memory bandwidth on paper, and who have the space and power budget for a larger card, may examine the LX MAX, though no measured results support its theoretical advantages. The recorded data favors the RTX 4000 SFF Ada Generation for verified performance and feature completeness.
