NVIDIA N1 16SM vs Lisuan Tech LX PRO Comparison

Head-to-Head Benchmarks

The database records no overlapping benchmark submissions for the NVIDIA N1 16SM and the Lisuan Tech LX PRO, so a direct score-by-score comparison is not possible from measured results. Instead, the comparison must rely on the recorded architectural and specification data for each part, which differ substantially across nearly every measurable field.

The Lisuan Tech LX PRO holds the clear advantage in raw compute throughput. Its FP32 rating of 24.58 TFLOPS is more than 2.5 times the NVIDIA N1 16SM's 9.609 TFLOPS. In FP16 workloads, the gap widens further: the LX PRO delivers 49.15 TFLOPS with a 2:1 FP16-to-FP32 ratio, while the N1 16SM delivers 9.609 TFLOPS at a 1:1 ratio. This means the LX PRO processes FP16 data at approximately five times the rate of the N1 16SM. The texture rate follows the same pattern, with the LX PRO at 384.0 GTexel/s versus 300.3 GTexel/s for the N1 16SM, a 28% margin. Pixel throughput shows the largest relative difference: the LX PRO renders at 192.0 GPixel/s, which is 3.4 times the N1 16SM's 56.30 GPixel/s.

Memory bandwidth also favors the LX PRO decisively. The LX PRO's 432.0 GB/s over a 192-bit GDDR6 interface exceeds the N1 16SM's 273.2 GB/s over a 256-bit LPDDR5X interface by 58%. The effective memory clock of 18 Gbps on the LX PRO doubles the 8.5 Gbps effective rate of the N1 16SM. However, the N1 16SM counters with a far larger memory capacity: 128 GB versus 24 GB. This is a five-fold difference in capacity, which changes the nature of the workloads each part can accommodate.

The N1 16SM does hold advantages in other areas. Its boost clock of 2346 MHz is recorded, while the LX PRO has no base or boost clock listed in the database, so clock-for-clock comparison is incomplete. The N1 16SM uses a PCIe 5.0 x16 interface, which is one generation newer than the LX PRO's PCIe 4.0 x16. The N1 16SM also carries dedicated ray tracing cores (16) and tensor cores (64), while the LX PRO lists neither, indicating those specialized units are absent or unconfirmed. The N1 16SM's process node is 5 nm versus 6 nm for the LX PRO, and its die size of 382 mm² is recorded, while the LX PRO's die size is unknown.

Where Each One Wins

The Lisuan Tech LX PRO wins in every throughput-oriented category that the database tracks. For compute-heavy tasks, the LX PRO's FP32 and FP16 figures place it in a higher performance class. The 24.58 TFLOPS FP32 rating and 49.15 TFLOPS FP16 rating suggest workloads such as large matrix operations, simulation, or high-resolution rendering would complete faster on the LX PRO. The 192.0 GPixel/s pixel rate and 384.0 GTexel/s texture rate indicate strong fill-rate performance for rasterization-heavy scenes. The 432.0 GB/s memory bandwidth supports these compute rates, allowing data to feed the 6144 shading units and 192 texture mapping units without as much bottleneck pressure. The LX PRO also supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.3, making it applicable to modern graphics APIs.

The NVIDIA N1 16SM wins in capacity and integration features. Its 128 GB of LPDDR5X memory is unmatched by the LX PRO's 24 GB, making the N1 16SM suitable for data sets that exceed the LX PRO's memory ceiling. The N1 16SM's 16 ray tracing cores and 64 tensor cores provide hardware acceleration for ray-traced graphics and AI inference tasks, respectively, which the LX PRO cannot claim from the recorded data. The N1 16SM's PCIe 5.0 x16 interface offers double the per-lane bandwidth of PCIe 4.0, which matters for data transfer between the GPU and host system. The N1 16SM is also an IGP with no power connectors and no slot width, meaning it integrates into a system without occupying an expansion slot, whereas the LX PRO is a dual-slot card requiring a 16-pin power connector and a suggested 550 W power supply. The N1 16SM's 5 nm process node indicates a more advanced manufacturing process than the 6 nm node of the LX PRO, which can affect power efficiency and thermal behavior, though the N1 16SM's TDP is unknown while the LX PRO's TDP is recorded at 225 W.

The N1 16SM's release date of May 31, 2026 is later than the LX PRO's March 16, 2026, so the N1 16SM is the more recent introduction. Both parts are marked as Active in production status, and both sit at the 50th percentile versus all GPUs in the database, with average benchmark scores of zero due to the absence of recorded benchmark results.

The Verdict

The data points to two distinct use cases rather than a single winner. For applications that depend on raw compute throughput, memory bandwidth, and fill rates, the Lisuan Tech LX PRO is the stronger choice based on its 24.58 TFLOPS FP32, 49.15 TFLOPS FP16, 192.0 GPixel/s pixel rate, and 432.0 GB/s bandwidth. These figures are multiples of the N1 16SM's corresponding values, and no recorded data on the N1 16SM closes that gap.

For applications that require very large memory capacity, hardware ray tracing, or AI acceleration, the NVIDIA N1 16SM is the only option among the two. Its 128 GB memory capacity is five times the LX PRO's 24 GB, and its 16 ray tracing cores and 64 tensor cores provide dedicated hardware that the LX PRO does not list. The N1 16SM's IGP form factor and lack of power connectors also make it suitable for systems where a discrete dual-slot card with a 225 W TDP and a 16-pin connector cannot be accommodated.

The percentile ranking of both parts at 50 means the database places them at the median of all recorded GPUs, but this is based on no benchmark scores, so it should be read as a placeholder rather than a performance assessment. The LX PRO's higher throughput metrics in every compute category suggest it would rank higher in compute-oriented benchmarks if such results were recorded. The N1 16SM's larger memory and specialized cores suggest it would rank higher in capacity-constrained or ray-tracing workloads. The choice comes down to whether the workload is compute-bound or capacity/feature-bound.

Architecture Differences

The two GPUs are built on different architectures from different generations. The NVIDIA N1 16SM uses the GB20B chip based on the Blackwell 2.0 architecture, part of the Blackwell IGP (N1x) generation. The Lisuan Tech LX PRO uses the 7G105 chip based on the TrueGPU architecture, part of the 7G100 generation. These are unrelated design lineages with different design priorities.

The N1 16SM is fabricated on a 5 nm process at TSMC with a die size of 382 mm². The LX PRO is fabricated on a 6 nm process at the same foundry, TSMC, with an unknown die size. The smaller process node on the N1 16SM allows for higher transistor density, though the transistor count for both parts is listed as unknown. The N1 16SM's 2048 shading units, 128 TMUs, and 24 ROPs are substantially fewer than the LX PRO's 6144 shading units, 192 TMUs, and 96 ROPs, indicating the LX PRO is designed for wider parallel execution.

The N1 16SM includes 16 ray tracing cores and 64 tensor cores, which are dedicated hardware units for ray tracing and tensor operations. The LX PRO lists no ray tracing cores and no tensor cores, suggesting either their absence or a lack of recorded data for those units. The N1 16SM's FP16 performance matches its FP32 at 9.609 TFLOPS with a 1:1 ratio, meaning it does not double FP16 throughput. The LX PRO's FP16 performance of 49.15 TFLOPS uses a 2:1 ratio, doubling its FP32 rate, which indicates a design that accelerates FP16 compute.

The N1 16SM is an IGP with no slot width, no power connectors, and a single HDMI output. The LX PRO is a dual-slot card with a 16-pin power connector, a 225 W TDP, a suggested 550 W power supply, and four DisplayPort 1.4a outputs. The N1 16SM reports no DirectX, OpenGL, or Vulkan API support in the database, while the LX PRO reports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.3. The N1 16SM's lack of recorded API support may reflect its IGP nature or incomplete data entry, but as recorded, the LX PRO is the only one with confirmed graphics API compatibility.
