NVIDIA N1X 40SM vs Lisuan Tech LX MAX Comparison

Head-to-Head Benchmarks

The database contains no head-to-head benchmark results for the NVIDIA N1X 40SM and the Lisuan Tech LX MAX. Neither GPU has recorded benchmark scores, average benchmark scores of zero, and both sit at the 50th percentile versus all GPUs in the database. The wins count is zero for each side, meaning there is no measured performance data to compare directly. Without benchmark results, the comparison must rely entirely on the specification differences between the two cards.

The absence of benchmark data is itself a notable finding. The NVIDIA N1X 40SM is an integrated graphics processor (IGP) with a PCIe 5.0 x16 interface, while the Lisuan Tech LX MAX is a dual-slot discrete card with a PCIe 4.0 x16 interface. These form factors suggest very different intended use cases, yet neither has been subjected to the database's standard benchmark suite. The percentile ranking of 50 for both indicates they sit at the median of all recorded GPUs, but this ranking is based on specifications and availability rather than measured performance.

Where Each One Wins

Since no benchmark wins are recorded, the analysis shifts to what the specification data implies about each GPU's strengths. The NVIDIA N1X 40SM delivers 24.02 TFLOPS of FP32 performance and the same 24.02 TFLOPS for FP16 with a 1:1 ratio. Its 5120 shading units, 320 texture mapping units, and 40 render output units are paired with 40 ray tracing cores and 160 tensor cores. This makes it a heavily compute-focused IGP with substantial AI and ray tracing hardware for an integrated solution.

The Lisuan Tech LX MAX produces 24.58 TFLOPS of FP32 performance, slightly ahead of the NVIDIA part, and 49.15 TFLOPS of FP16 performance with a 2:1 ratio. This means the LX MAX can deliver twice the half-precision throughput of the N1X 40SM, which is a significant advantage for workloads that can utilize FP16 arithmetic. The LX MAX also has 6144 shading units, which is 1024 more than the N1X 40SM, but only 192 texture mapping units and 96 render output units. Its pixel rate of 192.0 GPixel/s is more than double the N1X 40SM's 93.84 GPixel/s, while its texture rate of 384.0 GTexel/s is roughly half the N1X 40SM's 750.7 GTexel/s.

Memory bandwidth splits the two GPUs sharply. The LX MAX uses 12 GB of GDDR6 memory on a 192-bit bus, delivering 432.0 GB/s of bandwidth. The N1X 40SM uses 128 GB of LPDDR5X memory on a 256-bit bus, but delivers only 273.2 GB/s. The LX MAX has 58% more memory bandwidth, which matters for memory-bound workloads. The N1X 40SM has over ten times the memory capacity, which is unusual for any GPU and suggests a focus on large in-memory datasets.

Architecture Differences

The NVIDIA N1X 40SM is built on the GB20B chip using the Blackwell 2.0 architecture, part of the Blackwell IGP generation for the N1x platform. It is fabricated on a 5 nm process at TSMC with a die size of 382 mm². The Lisuan Tech LX MAX uses the 7G106 chip with the TrueGPU architecture, belonging to the 7G100 generation. It is fabricated on a 6 nm process at TSMC, with the die size listed as unknown. The process node difference is one generation apart, with the N1X 40SM using the smaller process.

The NVIDIA GPU has 40 ray tracing cores and 160 tensor cores, while the LX MAX lists no ray tracing cores and no tensor cores in its specifications. This is a fundamental architectural divergence. The N1X 40SM is designed with dedicated hardware for ray tracing and tensor operations, which are essential for modern graphics effects and AI acceleration. The LX MAX's TrueGPU architecture does not expose these units, meaning any ray tracing or tensor workloads would need to run on its general-purpose shading units.

API support also differs substantially. The N1X 40SM lists DirectX, OpenGL, and Vulkan as N/A, meaning it does not support these standard graphics APIs. The LX MAX supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.3. This makes the LX MAX compatible with a wide range of modern games and applications, while the N1X 40SM would require a different software stack entirely. The display outputs reflect this: the N1X 40SM has a single HDMI output, while the LX MAX has four DisplayPort 1.4a outputs.

Clock speeds show a notable difference in operating characteristics. The N1X 40SM has a base clock of 741 MHz and a boost clock of 2346 MHz, with memory running at 1067 MHz (8.5 Gbps effective). The LX MAX has no base or boost clock listed, but its memory runs at 2250 MHz (18 Gbps effective), more than double the N1X 40SM's memory clock. The power envelope is also very different: the N1X 40SM has no listed TDP and uses no power connectors, while the LX MAX has a 225 W TDP and requires a single 16-pin power connector with a suggested 550 W power supply.

The Verdict

The data shows two GPUs with nearly identical FP32 compute throughput but radically different designs. The NVIDIA N1X 40SM achieves 24.02 TFLOPS of FP32, while the Lisuan Tech LX MAX achieves 24.58 TFLOPS, a difference of roughly 2%. In FP16, the LX MAX pulls ahead decisively with 49.15 TFLOPS versus 24.02 TFLOPS, a 2:1 advantage. For workloads that use half-precision arithmetic, the LX MAX is the clear choice based on raw throughput.

The N1X 40SM counters with 128 GB of memory, which dwarfs the LX MAX's 12 GB. This is a 10.7x difference in capacity. For applications that need to hold very large datasets on the GPU, such as certain AI inference or scientific computing tasks, the N1X 40SM's memory capacity is unmatched. However, its 273.2 GB/s bandwidth is lower than the LX MAX's 432.0 GB/s, so data movement would be slower despite the larger pool.

The N1X 40SM has ray tracing and tensor cores, while the LX MAX does not. This makes the N1X 40SM the only option for workloads that rely on those dedicated units, provided the software supports the Blackwell IGP platform. The LX MAX has full DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.3 support, making it the only one of the two that can run standard PC games and graphics applications. The N1X 40SM's lack of these APIs means it cannot function as a conventional gaming GPU.

The LX MAX also has a higher pixel rate at 192.0 GPixel/s versus 93.84 GPixel/s, which suggests better fill-rate performance for rasterization. Its texture rate is lower at 384.0 GTexel/s versus 750.7 GTexel/s, indicating the N1X 40SM has stronger texturing throughput. These opposing strengths make either GPU preferable depending on the specific rendering workload.

For users who need standard graphics API compatibility, a compact dual-slot card with DisplayPort outputs, and strong FP16 performance, the LX MAX is the only viable option from the data. For users who need massive memory capacity, integrated graphics with no power connectors, and dedicated ray tracing and tensor hardware, the N1X 40SM is the choice. The absence of benchmark results means neither GPU has proven performance in the database, so any selection must be based on specification fit rather than measured results.
