NVIDIA RTX A400 vs Lisuan Tech LX 7G100 Comparison

The Verdict

The NVIDIA RTX A400 and Lisuan Tech LX 7G100 serve completely different purposes. The RTX A400 is a low-profile, power-efficient workstation card designed for basic professional workloads and multi-display setups. It delivers a 35th percentile ranking among all GPUs in the database, with an average benchmark score of 6078. The LX 7G100, by contrast, sits at the 50th percentile, but its benchmark data is empty, meaning its competitive position cannot be quantified from recorded measurements. The database contains no head-to-head benchmark results and no wins recorded for either card.

For users needing a compact, single-slot card with minimal power draw and four mini-DisplayPort outputs, the RTX A400 is the documented choice. For users requiring 12 GB of memory, a 192-bit bus, and substantially higher raw compute throughput, the LX 7G100 is the only option with those specifications. The data shows no overlap in their intended use cases: one is a low-power workstation add-in card, the other is a high-throughput compute-oriented board.

Architecture Differences

The RTX A400 uses the GA107 chip built on the Ampere architecture, manufactured on an 8 nm process at Samsung. It packs 8,700 million transistors into a 200 mm² die, yielding a transistor density of 43.5 million per mm². The LX 7G100 uses the 7G106 chip on a "TrueGPU" architecture, fabricated on a 6 nm process at TSMC. Its transistor count and die size are not recorded in the database.

The RTX A400 features 768 shading units, 24 texture mapping units, 16 ROPs, 6 RT cores, and 24 tensor cores. The LX 7G100 has 6144 shading units, 192 TMUs, and 96 ROPs, but no RT core or tensor core counts are listed. The LX 7G100's FP32 throughput is 24.58 TFLOPS, roughly nine times the RTX A400's 2.706 TFLOPS. The LX 7G100 also doubles FP16 performance to 49.15 TFLOPS with a 2:1 ratio, while the RTX A400's FP16 matches its FP32 at 2.706 TFLOPS with a 1:1 ratio.

The RTX A400 supports PCIe 4.0 x8, while the LX 7G100 uses PCIe 4.0 x16. Both support DirectX 12 Ultimate (12_2) and OpenGL 4.6. The RTX A400 supports Vulkan 1.4, while the LX 7G100 supports Vulkan 1.3.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark results between the RTX A400 and LX 7G100. Each card's wins count is zero. However, the RTX A400 has individual benchmark scores, while the LX 7G100 has none recorded.

The RTX A400's recorded scores include Geekbench OpenCL at 22844, Geekbench Vulkan at 22237, Passmark DirectX 10 at 32, DirectX 11 at 37, DirectX 12 at 27, DirectX 9 at 87, G2D at 899, G3D at 5983, and GPU compute at 2557. Its average benchmark score is 6078, placing it at the 35th percentile among all GPUs.

The LX 7G100 has no benchmark entries, no average score, and no nearest rivals. Its percentile of 50 is recorded but unsupported by any measured data. The RTX A400's nearest rivals are all low-to-mid-range cards: the GeForce MX230 (delta 0%), Quadro P2000 (0.5% ahead), Iris Pro Graphics 6200 (0.6% behind), and Radeon 760M (1% ahead).

Without LX 7G100 benchmark data, no direct performance comparison can be made. The specification gap suggests the LX 7G100 should dominate in compute-heavy workloads based on its FP32, memory bandwidth, texture rate, and pixel rate figures, but the database does not confirm this with actual scores.

Where Each One Wins

For low-power, compact workstation use: the RTX A400 wins. It draws 50 W, needs no power connectors, fits in a single slot, and measures just 163 mm long. Its 250 W suggested PSU means it can drop into nearly any existing system. Four mini-DisplayPort 1.4a outputs support multi-display setups. The 4 GB GDDR6 memory and 96.00 GB/s bandwidth are modest, but the card's 35th percentile ranking at least places it with usable performance for basic 2D and light 3D workloads, as evidenced by its Passmark G3D score of 5983 and GPU compute score of 2557.

For compute-heavy, memory-hungry workloads: the LX 7G100 wins on paper. Its 12 GB GDDR6 on a 192-bit bus delivers 432.0 GB/s, 4.5 times the RTX A400's bandwidth. FP32 throughput of 24.58 TFLOPS is approximately nine times higher. The 384.0 GTexel/s texture rate and 192.0 GPixel/s pixel rate dwarf the RTX A400's 42.29 GTexel/s and 28.19 GPixel/s. The 6144 shading units give it eight times the shader count. PCIe 4.0 x16 provides double the bus bandwidth of the RTX A400's x8 connection.

For users running DirectX 12 Ultimate workloads: both cards support the full 12_2 feature set. For Vulkan applications: the RTX A400 supports Vulkan 1.4, while the LX 7G100 supports Vulkan 1.3, a minor version difference that may matter for specific extensions.

For physical installation: the RTX A400 fits in small chassis with its 163 mm length and single-slot profile. The LX 7G100 requires a full-size case: 294 mm long, 120 mm tall, 49 mm wide, dual-slot, plus clearance for an 8-pin power connector.

For systems with limited PSU headroom: the RTX A400's 50 W TDP and no connectors make it the safe pick. The LX 7G100's 225 W TDP and 550 W suggested PSU demands a substantial power supply.

For software compatibility: both support DirectX 12 Ultimate, OpenGL 4.6, and Vulkan, so API-level compatibility is similar. The LX 7G100 lacks recorded RT cores and tensor cores, so AI acceleration and ray tracing features cannot be verified from the database. The RTX A400 explicitly lists 6 RT cores and 24 tensor cores, confirming those capabilities.

The data shows no scenario where both cards serve the same role. The RTX A400 is a documented, benchmarked low-power workstation card. The LX 7G100 is an unbenchmarked, high-specification compute card whose real-world performance remains unmeasured. Buyers seeking verified performance numbers should look at the RTX A400's recorded scores. Buyers needing maximum memory and compute throughput on paper should consider the LX 7G100, but the database provides no evidence of its actual performance.
