NVIDIA N1X 48SM vs Lisuan Tech LX PRO Comparison

Where Each One Wins

The benchmark database shows a clean split between these two accelerators, with no head-to-head benchmark results recorded and zero wins recorded for either part. The differentiation therefore comes from the architectural profiles and the recorded feature sets rather than from direct performance comparisons.

The NVIDIA N1X 48SM is an integrated graphics processor (IGP) built on the Blackwell 2.0 architecture with a 5 nm process node. It pairs 6144 shading units with 192 tensor cores and 48 ray tracing cores, delivering 28.83 TFLOPS FP32 and the same 28.83 TFLOPS FP16 at a 1:1 ratio. Its memory subsystem uses 128 GB of LPDDR5X on a 256-bit bus for 273.2 GB/s of bandwidth. This configuration points toward workloads that favor large memory capacity, unified memory access patterns, and FP32 compute throughput. The 1:1 FP16 ratio indicates that the N1X treats FP16 and FP32 with equal throughput, which suits applications that do not require the doubled FP16 rate found in some competing designs.

The Lisuan Tech LX PRO is a discrete, dual-slot card built on the TrueGPU architecture with a 6 nm process node. It also has 6144 shading units, but its tensor cores and ray tracing cores are not recorded in the database. Its memory configuration is 24 GB of GDDR6 on a 192-bit bus, delivering 432.0 GB/s of bandwidth. The LX PRO achieves 24.58 TFLOPS FP32 and 49.15 TFLOPS FP16 at a 2:1 ratio. The higher FP16 throughput and the substantially larger memory bandwidth give the LX PRO an edge in workloads that can exploit mixed-precision arithmetic or that are bandwidth-limited. The 192.0 GPixel/s pixel rate and 384.0 GTexel/s texture rate indicate strong rasterization throughput per clock, while the N1X counters with 112.6 GPixel/s and 900.9 GTexel/s, the latter reflecting its 384 TMUs versus the LX PRO's 192.

The wins distribution effectively separates the two by form factor and memory strategy. The N1X wins on FP32 compute, texture throughput, and memory capacity. The LX PRO wins on FP16 compute, memory bandwidth, pixel throughput, and API support. Neither part has recorded benchmark scores, so the analysis relies on the recorded specifications.

Architecture Differences

The two accelerators diverge at the silicon level. The NVIDIA N1X 48SM uses the GB20B chip under the Blackwell 2.0 architecture, fabricated by TSMC on a 5 nm process. Its die size is recorded at 382 mm². The Lisuan Tech LX PRO uses the 7G105 chip under the TrueGPU architecture, also fabricated by TSMC but on a 6 nm process; its die size is not recorded in the database.

The N1X integrates 384 texture mapping units and 48 ROPs, while the LX PRO has 192 TMUs and 96 ROPs. This means the N1X has exactly double the texture units of the LX PRO, while the LX PRO has exactly double the ROPs of the N1X. The N1X's 900.9 GTexel/s texture rate reflects its TMU count, and the LX PRO's 192.0 GPixel/s pixel rate reflects its ROP count.

Memory architecture differs fundamentally. The N1X uses 128 GB of LPDDR5X on a 256-bit bus with 273.2 GB/s bandwidth. The LX PRO uses 24 GB of GDDR6 on a 192-bit bus with 432.0 GB/s bandwidth. The LX PRO delivers 158.8 GB/s more bandwidth than the N1X, despite having a narrower bus, because its memory clock runs at 2250 MHz with 18 Gbps effective, compared to the N1X's 1067 MHz with 8.5 Gbps effective.

Compute ratios differ as well. The N1X records FP16 at 28.83 TFLOPS with a 1:1 ratio to FP32, meaning it does not double FP16 throughput. The LX PRO records FP16 at 49.15 TFLOPS with a 2:1 ratio, meaning it doubles FP16 throughput relative to FP32. The LX PRO's FP16 figure is 20.32 TFLOPS higher than the N1X's FP16 figure, while the N1X's FP32 figure is 4.25 TFLOPS higher than the LX PRO's FP32 figure.

The N1X includes 192 tensor cores and 48 RT cores, both absent from the LX PRO's recorded specifications. The N1X is an IGP with no power connectors and no recorded TDP, while the LX PRO is a dual-slot card with a 225 W TDP, a single 16-pin power connector, and a suggested 550 W PSU. The N1X uses PCIe 5.0 x16, while the LX PRO uses PCIe 4.0 x16. The N1X has one HDMI output, while the LX PRO has four DisplayPort 1.4a outputs.

API support also separates the two. The N1X records N/A for DirectX, OpenGL, and Vulkan, while the LX PRO supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.3.

The Verdict

The recorded data indicates that the NVIDIA N1X 48SM is the appropriate choice for compute-heavy workloads that prioritize FP32 throughput, large memory capacity, and texture processing. Its 28.83 TFLOPS FP32 places it ahead of the LX PRO by 4.25 TFLOPS, and its 128 GB memory capacity dwarfs the LX PRO's 24 GB. The 900.9 GTexel/s texture rate, driven by 384 TMUs, gives it a strong advantage in texture-bound scenarios. The presence of 192 tensor cores and 48 RT cores suggests the N1X carries dedicated acceleration hardware, although no benchmark scores exist to quantify their impact.

The Lisuan Tech LX PRO is the appropriate choice for workloads that can exploit FP16 arithmetic, require higher memory bandwidth, or depend on standard graphics APIs. Its 49.15 TFLOPS FP16 is 20.32 TFLOPS higher than the N1X's FP16 figure. Its 432.0 GB/s bandwidth is 158.8 GB/s higher than the N1X's. Its 192.0 GPixel/s pixel rate, driven by 96 ROPs, doubles the N1X's pixel throughput. The LX PRO also records full DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.3 support, whereas the N1X records no API support at all.

The form factor difference matters. The N1X is an IGP with no power connectors and no recorded TDP, meaning it requires no discrete power delivery. The LX PRO is a dual-slot card with a 225 W TDP, a 16-pin connector, and a 550 W suggested PSU. The LX PRO measures 248 mm by 118 mm by 48 mm.

The percentile ranking for both parts is 50, and both have an average benchmark score of 0. Neither has any recorded head-to-head benchmark results, so the verdict is based entirely on the specification differences recorded in the database.
