Where Each One Wins

The recorded data reveals a clear split between mobility and raw throughput. The RTX 3500 Mobile wins in power efficiency and portability: it is an IGP with a 100 W TDP, meaning it can be integrated directly into laptops without external power connectors. The LX ULTRA, by contrast, is a dual-slot desktop card with a 225 W TDP and a dedicated 16-pin power connector. For systems where space and power draw are constrained, the RTX 3500 Mobile is the only viable option.

The LX ULTRA wins decisively in raw compute and rendering capacity. It has 6144 shading units against 5120 on the RTX 3500 Mobile, 192 texture mapping units against 160, and 96 raster output pipelines against 64. Its pixel rate of 192.0 GPixel/s is nearly double the RTX 3500 Mobile's 98.88 GPixel/s. Texture rate on the LX ULTRA reaches 384.0 GTexel/s, compared to 247.2 GTexel/s on the NVIDIA part. These advantages translate directly to higher fill-rate workloads, such as high-resolution rendering with heavy texture sampling.

Memory capacity is another decisive win for the LX ULTRA. With 24 GB versus 12 GB, it can hold larger datasets, textures, and geometry in VRAM. For workloads that exceed 12 GB, the RTX 3500 Mobile would spill to system memory, while the LX ULTRA stays entirely on-GPU. The bandwidth is identical at 432.0 GB/s, so the extra capacity does not come with added speed, but capacity itself is a separate advantage.

The RTX 3500 Mobile counters with architectural features the LX ULTRA lacks. It includes 40 ray tracing cores and 160 tensor cores, while the LX ULTRA lists no RT cores and no tensor cores. This gives the RTX 3500 Mobile dedicated hardware for ray-traced rendering and AI-accelerated workloads, capabilities the LX ULTRA's TrueGPU architecture does not expose in the data.

Architecture Differences

The two GPUs come from fundamentally different design lineages. The RTX 3500 Mobile uses the AD104 chip based on NVIDIA's Ada Lovelace architecture, fabricated by TSMC on a 5 nm process. The transistor count is 35,800 million on a die size of 294 mm², yielding a density of 121.8 million transistors per square millimeter. The LX ULTRA uses the 7G105 chip with the TrueGPU architecture, fabricated by TSMC on a 6 nm process. Its transistor count and die size are listed as unknown, so no density comparison is possible.

The Ada Lovelace architecture in the RTX 3500 Mobile includes dedicated ray tracing cores (40 of them) and tensor cores (160 of them), which are absent from the LX ULTRA's specification list. This indicates the RTX 3500 Mobile is designed for hybrid workloads combining rasterization, ray tracing, and AI inference. The LX ULTRA's TrueGPU architecture appears focused on pure raster compute, given its higher shading unit count and FP32 throughput but no specialized acceleration blocks.

FP16 processing reveals a major architectural divergence. The RTX 3500 Mobile delivers 15.82 TFLOPS in FP16 with a 1:1 ratio to FP32, meaning it treats FP16 and FP32 at equal throughput. The LX ULTRA delivers 49.15 TFLOPS in FP16 with a 2:1 ratio, meaning FP16 runs at twice the rate of FP32. This suggests the LX ULTRA has a fundamentally different compute pipeline optimized for half-precision math, potentially for workloads like machine learning inference or image processing that tolerate reduced precision.

The transistor density figures belong only to the RTX 3500 Mobile: 35,800 million transistors packed into 294 mm². The 5 nm process allows this density, while the LX ULTRA's 6 nm process likely offers lower density, but the data does not confirm this since its die size is unknown. The RTX 3500 Mobile's architecture is also newer in lineage, with a predecessor in Ampere-MW and a successor in Blackwell-MW, while the LX ULTRA stands alone with no recorded predecessor or successor.

Head-to-Head Benchmarks

The head-to-head benchmark data is empty, but the specification-derived performance indicators provide a comprehensive comparison. The most significant wins for the LX ULTRA come in throughput metrics. Its FP32 output of 24.58 TFLOPS is 55% higher than the RTX 3500 Mobile's 15.82 TFLOPS, a substantial margin for any compute-bound workload. In FP16, the LX ULTRA's 49.15 TFLOPS is 210% higher, more than triple the RTX 3500 Mobile's 15.82 TFLOPS. This makes the LX ULTRA particularly dominant in half-precision tasks.

The pixel rate difference is even more pronounced on a percentage basis. The LX ULTRA's 192.0 GPixel/s is 94% higher than the RTX 3500 Mobile's 98.88 GPixel/s. For rasterization-heavy scenes with high resolution and anti-aliasing, this near-doubling of fill rate can translate directly into higher frame rates. The texture rate gap is 55%: 384.0 GTexel/s versus 247.2 GTexel/s. This benefits the LX ULTRA in texture-rich environments like open-world games or 3D rendering with complex materials.

The RTX 3500 Mobile's wins are architectural rather than raw-throughput based. Its 40 RT cores and 160 tensor cores provide dedicated hardware that the LX ULTRA does not list at all. In ray-traced workloads, the RTX 3500 Mobile can offload intersection and shading calculations to specialized units, while the LX ULTRA would rely on general-purpose shaders. Similarly, tensor cores accelerate matrix operations for AI inference and DLSS-style upscaling, capabilities absent from the LX ULTRA's specification.

Power efficiency is a clear win for the RTX 3500 Mobile. At 100 W TDP, it delivers 15.82 TFLOPS with a per-watt efficiency of 158.2 GFLOPS/W. The LX ULTRA at 225 W delivers 24.58 TFLOPS, a per-watt efficiency of 109.2 GFLOPS/W. The RTX 3500 Mobile is 45% more efficient in FP32 per watt. This matters for sustained workloads in thermally constrained environments, where the LX ULTRA's higher power draw would require more substantial cooling.

The Verdict

The data points to two distinct use cases. The RTX 3500 Mobile Ada Generation is designed for mobile workstations where power consumption, physical space, and specialized acceleration matter. Its 100 W TDP, IGP form factor, and absence of power connectors make it suitable for laptops. Its 40 RT cores and 160 tensor cores provide ray tracing and AI acceleration that the LX ULTRA cannot offer. The 12 GB memory capacity is sufficient for many professional workloads, though it is half the LX ULTRA's 24 GB.

The Lisuan Tech LX ULTRA is a desktop-oriented card with a dual-slot form factor, 268 mm length, and 225 W TDP. It demands a 550 W PSU and a 16-pin connector. In exchange, it delivers 55% higher FP32, 210% higher FP16, 94% higher pixel rate, and 55% higher texture rate than the RTX 3500 Mobile. Its 24 GB memory capacity doubles the NVIDIA part, and its 96 ROPs support higher fill rates. The LX ULTRA's 6 nm TrueGPU architecture prioritizes raw compute over specialized features, and its Vulkan 1.3 support is one version behind the RTX 3500 Mobile's 1.4.

The release dates reinforce this split. The RTX 3500 Mobile launched in March 2023, while the LX ULTRA launched in March 2026. The NVIDIA part sits within a lineage (predecessor Ampere-MW, successor Blackwell-MW), indicating an established product family. The LX ULTRA appears as a standalone entry with no recorded lineage. Both share identical memory bandwidth at 432.0 GB/s and the same 192-bit bus, so memory speed is not a differentiator.

The verdict is straightforward from the data. The RTX 3500 Mobile suits users who need ray tracing, tensor acceleration, low power draw, and a mobile form factor. The LX ULTRA suits users who prioritize raw FP32 and FP16 throughput, pixel and texture fill rates, and large memory capacity in a desktop chassis. The choice hinges on whether specialized acceleration and portability outweigh raw compute and memory size. Neither GPU dominates the other across all metrics; they are optimized for different environments.
