NVIDIA N1X 40SM vs Lisuan Tech LX 7G100 Comparison

Head-to-Head Benchmarks

The recorded database contains no head-to-head benchmark results for the NVIDIA N1X 40SM versus the Lisuan Tech LX 7G100. Both entries show zero benchmark scores, zero average scores, and zero wins in the comparison table. This means the dataset does not provide any measured performance deltas, percentile rankings among rivals, or specific application-level wins for either part. The only quantitative comparisons available come from the specification fields, which reveal distinct design targets.

The N1X 40SM delivers 24.02 TFLOPS FP32 and 24.02 TFLOPS FP16 at a 1:1 ratio, while the LX 7G100 reaches 24.58 TFLOPS FP32 and 49.15 TFLOPS FP16 at a 2:1 ratio. In raw FP32 throughput, the LX 7G100 holds a 0.56 TFLOPS lead, a margin of roughly 2.3% over the NVIDIA part. However, in FP16 compute, the LX 7G100 more than doubles the N1X 40SM, offering 49.15 TFLOPS versus 24.02 TFLOPS, which represents a 104.6% advantage. This suggests the Lisuan architecture is heavily optimized for half-precision workloads, whereas the NVIDIA part treats FP16 as a direct 1:1 extension of FP32.

Pixel throughput favors the LX 7G100 decisively. The Lisuan part achieves 192.0 GPixel/s against the N1X 40SM's 93.84 GPixel/s, a 104.6% increase. Texture throughput tells a different story: the NVIDIA part posts 750.7 GTexel/s, while the LX 7G100 manages 384.0 GTexel/s. The N1X 40SM leads by 366.7 GTexel/s, a 95.5% advantage in texel fill. These opposing strengths point to fundamentally different rasterization pipelines, with NVIDIA emphasizing texture work and Lisuan prioritizing pixel output.

Memory bandwidth also diverges sharply. The N1X 40SM uses 128 GB of LPDDR5X on a 256 bit bus, yielding 273.2 GB/s. The LX 7G100 uses 12 GB of GDDR6 on a 192 bit bus, delivering 432.0 GB/s. The Lisuan part leads by 158.8 GB/s, a 58.1% bandwidth advantage, despite having a narrower bus. This stems from the GDDR6 memory clock rated at 2250 MHz (18 Gbps effective) versus the LPDDR5X at 1067 MHz (8.5 Gbps effective). Higher memory clocks compensate for the narrower bus, giving the LX 7G100 substantially more memory throughput.

Neither part has recorded head-to-head wins, so the database cannot assign a victory count. Both occupy the 50th percentile among all GPUs, indicating they sit at the median of the performance distribution in the current dataset. Without benchmark scores, the percentile ranking carries no additional resolution.

The Verdict

The database shows two GPUs with opposite architectural priorities. The NVIDIA N1X 40SM is an integrated graphics processor with no dedicated PCIe power connections, a 5 nm process, and an IGP form factor. It leads in texture rate and ships with a massive 128 GB memory pool, but its memory bandwidth is lower than the Lisuan part. The Lisuan Tech LX 7G100 is a discrete dual-slot card with a 225 W TDP, a 6 nm process, and a full complement of display outputs. It dominates in FP16 compute, pixel rate, and memory bandwidth.

For workloads that depend on half-precision math, such as AI inference or certain compute shaders, the LX 7G100 is the clear choice based on its 49.15 TFLOPS FP16 output. For tasks that stress texture sampling, the N1X 40SM's 750.7 GTexel/s gives it a meaningful edge. The LX 7G100 also supports modern graphics APIs, while the N1X 40SM does not, which matters for gaming and DirectX 12 Ultimate applications. The N1X 40SM offers 128 GB of memory, which is 116 GB more than the LX 7G100, but that capacity comes with a slower bus and lower bandwidth.

The absence of benchmark scores means no direct performance ranking exists. The specification data alone points to the LX 7G100 as the more capable discrete solution for bandwidth-heavy and half-precision tasks, while the N1X 40SM serves as an integrated option with high texture throughput and very large memory capacity.

Specification Differences

The two parts differ in nearly every measured specification. The NVIDIA N1X 40SM uses a GB20B chip on Blackwell 2.0 architecture, fabricated on TSMC's 5 nm process with a 382 mm² die size. The Lisuan Tech LX 7G100 uses a 7G106 chip on TrueGPU architecture, fabricated on TSMC's 6 nm process with an unknown die size.

Clock behavior differs sharply. The N1X 40SM lists a base clock of 741 MHz and a boost clock of 2346 MHz. The LX 7G100 has no base or boost clock entries in the database. Memory clocks also diverge: the N1X 40SM runs at 1067 MHz (8.5 Gbps effective), while the LX 7G100 runs at 2250 MHz (18 Gbps effective).

Memory configurations are radically different. The N1X 40SM has 128 GB of LPDDR5X on a 256 bit bus with 273.2 GB/s bandwidth. The LX 7G100 has 12 GB of GDDR6 on a 192 bit bus with 432.0 GB/s bandwidth.

Shader resources differ: the N1X 40SM has 5120 shading units, 320 TMUs, and 40 ROPs. The LX 7G100 has 6144 shading units, 192 TMUs, and 96 ROPs. The NVIDIA part also includes 40 RT cores and 160 tensor cores, while the Lisuan part lists no RT or tensor core counts.

Power and physical specs diverge completely. The N1X 40SM has an unknown TDP, an IGP slot width, no power connectors, and no suggested PSU. The LX 7G100 has a 225 W TDP, dual-slot width, one 8-pin power connector, and a 550 W suggested PSU. The Lisuan card measures 294 mm by 120 mm by 49 mm, while the NVIDIA IGP has no listed dimensions.

Display outputs differ: the N1X 40SM has one HDMI port, while the LX 7G100 has four DisplayPort 1.4a outputs. The bus interface also differs, with the N1X 40SM using PCIe 5.0 x16 and the LX 7G100 using PCIe 4.0 x16.

API support is another key divider. The N1X 40SM lists N/A for DirectX, OpenGL, and Vulkan. The LX 7G100 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.3.

Release dates are close: the N1X 40SM launched on 2026-05-31, and the LX 7G100 launched on 2026-06-17. Both are listed as Active in production.

Architecture Differences

The NVIDIA N1X 40SM uses the Blackwell 2.0 architecture, built on TSMC's 5 nm process. Its die size is 382 mm². The architecture includes dedicated RT cores and tensor cores, with 40 RT cores and 160 tensor cores present. The FP16 path runs at a 1:1 ratio with FP32, meaning the hardware likely uses the same execution units for both precisions. The chip is branded as part of the Blackwell IGP (N1x) generation, and the lack of API support suggests it may be designed for specialized compute rather than general graphics.

The Lisuan Tech LX 7G100 uses the TrueGPU architecture, built on TSMC's 6 nm process. The die size is unknown. This architecture shows no RT or tensor core entries, yet it achieves 49.15 TFLOPS FP16 at a 2:1 ratio, indicating a distinct half-precision path that doubles throughput relative to FP32. The TrueGPU generation supports full modern graphics APIs, including DirectX 12 Ultimate, which implies a conventional rasterization pipeline with feature level 12_2.

The shading unit counts differ: 5120 for the NVIDIA part versus 6144 for the Lisuan part. However, the NVIDIA chip has 320 TMUs versus 192 for Lisuan, and 40 ROPs versus 96 for Lisuan. These ratios explain the texture and pixel rate outcomes. The NVIDIA architecture allocates more texture units per shading unit, while the Lisuan architecture allocates more ROPs per shading unit.

The memory architecture also reflects different design goals. The NVIDIA part uses LPDDR5X, a low-power memory typically paired with integrated processors, on a 256 bit bus. The Lisuan part uses GDDR6, a discrete graphics memory, on a 192 bit bus. The GDDR6 clock of 2250 MHz (18 Gbps effective) is more than double the LPDDR5X clock of 1067 MHz (8.5 Gbps effective), which compensates for the narrower bus and produces higher bandwidth.

Where Each One Wins

The NVIDIA N1X 40SM wins in texture throughput. Its 750.7 GTexel/s is 95.5% higher than the LX 7G100's 384.0 GTexel/s. This makes it the stronger candidate for workloads that repeatedly sample textures, such as certain procedural generation tasks or image processing pipelines that rely on texel fetches.

The NVIDIA part also wins on memory capacity. With 128 GB of LPDDR5X, it offers more than ten times the 12 GB of the LX 7G100. For datasets that must reside entirely in video memory, the N1X 40SM provides a large pool, albeit with lower bandwidth at 273.2 GB/s.

The Lisuan Tech LX 7G100 wins in pixel throughput. Its 192.0 GPixel/s is 104.6% higher than the N1X 40SM's 93.84 GPixel/s. Rasterization workloads that fill many pixels per frame, such as high-resolution rendering, benefit from this ROP advantage.

The LX 7G100 also wins in memory bandwidth. Its 432.0 GB/s is 58.1% higher than the N1X 40SM's 273.2 GB/s. This benefits bandwidth-sensitive operations like large data transfers, compute shaders with heavy memory access, and high-resolution texture streaming.

The Lisuan part wins in FP16 compute. Its 49.15 TFLOPS is 104.6% higher than the N1X 40SM's 24.02 TFLOPS. Applications that use half-precision arithmetic, including machine learning inference and certain graphics effects, see a substantial throughput advantage.

The LX 7G100 wins on API compatibility. It supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.3, while the N1X 40SM lists N/A for all three. Any graphics workload requiring these APIs must use the Lisuan part.

The N1X 40SM wins on FP32 efficiency relative to FP16, given its 1:1 ratio, but the LX 7G100 still holds a 2.3% FP32 lead. The NVIDIA part also has a smaller process node at 5 nm versus 6 nm, which could imply lower power draw per transistor, though TDP for the N1X 40SM is unknown. The LX 7G100 has a defined 225 W TDP and requires a 550 W PSU, while the N1X 40SM needs no power connector. In systems without discrete GPU power, the N1X 40SM is the only viable choice. In systems with a power supply and space for a 294 mm dual-slot card, the LX 7G100 offers higher bandwidth, pixel rate, and FP16 throughput.
