NVIDIA GeForce RTX 4090 Mobile vs Lisuan Tech LX 7G100 Comparison

The NVIDIA GeForce RTX 4090 Mobile and the Lisuan Tech LX 7G100 are two very different GPUs that happen to share a few surface-level specifications. The RTX 4090 Mobile is a laptop-class part built on a 5 nm process, while the LX 7G100 is a dual-slot desktop card on a 6 nm node. The recorded data shows that the RTX 4090 Mobile has a substantial benchmark presence, while the LX 7G100 has no recorded benchmark scores in the database. This creates a comparison where one side is fully quantified and the other is defined solely by its architecture and specifications.

The Verdict

The data points to a clear split based on workload and form factor. The NVIDIA GeForce RTX 4090 Mobile delivers a large set of measured benchmark scores across multiple tests, including Geekbench OpenCL at 180831 and Passmark G3D at 27212. Its average benchmark score sits at 43667, placing it in the 84th percentile of all GPUs tracked in the database. For anyone needing a mobile solution with proven performance, the RTX 4090 Mobile is the only choice with empirical support.

The Lisuan Tech LX 7G100 has zero recorded benchmarks, an average benchmark score of 0, and a 50th percentile ranking by default. Its specifications show a 12 GB memory configuration, a 192-bit memory bus, and a 225 W power draw, but without test results, the database cannot confirm how those specs translate into real-world performance. The LX 7G100 might be selected for desktop builds where a dual-slot card with four DisplayPort outputs is preferred, but the absence of data means no performance verdict can be made.

For compute-heavy tasks like OpenCL workloads, the RTX 4090 Mobile is the only option with recorded evidence. The LX 7G100 offers a different feature set, including a 2:1 FP16 ratio, but lacks any benchmark confirmation. The verdict from the data is straightforward: the RTX 4090 Mobile is the verified performer, while the LX 7G100 remains an unquantified alternative.

Architecture Differences

The two GPUs diverge at the most fundamental level. The RTX 4090 Mobile uses the AD103 chip with NVIDIA’s Ada Lovelace architecture, built on a 5 nm process at TSMC. It contains 45,900 million transistors on a 379 mm² die, yielding a transistor density of 121.1M per mm². The LX 7G100 uses the 7G106 chip with an architecture called TrueGPU, built on a 6 nm process, also at TSMC. Its transistor count and die size are listed as unknown in the database.

The RTX 4090 Mobile has 9728 shading units, 304 texture mapping units, and 112 raster output units. It also includes 76 ray tracing cores and 304 tensor cores, which are absent from the LX 7G100’s specification list. The LX 7G100 has 6144 shading units, 192 TMUs, and 96 ROPs, with no ray tracing or tensor core data recorded.

Clock behavior differs as well. The RTX 4090 Mobile has a base clock of 1335 MHz and a boost clock of 1695 MHz. The LX 7G100 has no base or boost clock values in the database. Both use GDDR6 memory with a 2250 MHz memory clock and 18 Gbps effective speed, but the RTX 4090 Mobile has 16 GB on a 256-bit bus, while the LX 7G100 has 12 GB on a 192-bit bus. That yields memory bandwidth of 576.0 GB/s for the RTX 4090 Mobile versus 432.0 GB/s for the LX 7G100.

The FP32 throughput is 32.98 TFLOPS for the RTX 4090 Mobile and 24.58 TFLOPS for the LX 7G100. The FP16 numbers differ more sharply: the RTX 4090 Mobile achieves 32.98 TFLOPS with a 1:1 ratio, while the LX 7G100 reaches 49.15 TFLOPS with a 2:1 ratio. This indicates the LX 7G100 is designed for FP16-heavy workloads, even though no benchmarks confirm this advantage.

API support also separates them. Both support DirectX 12 Ultimate (12_2) and OpenGL 4.6. The RTX 4090 Mobile supports Vulkan 1.4, while the LX 7G100 is limited to Vulkan 1.3. The production status for both is Active, but the RTX 4090 Mobile has a release date of 2023-01-02, while the LX 7G100 is dated 2026-06-17.

The RTX 4090 Mobile sits between these competitors, slightly ahead of the M6000 variants and slightly behind the RTX A6000.

The LX 7G100 has no benchmark results, no nearest rivals, and an average score of 0. Its percentile rank of 50 is a default placeholder, not a measured position. The data cannot show any head-to-head wins for the LX 7G100 because no tests were recorded.

Where Each One Wins

The RTX 4090 Mobile wins in every measured category. Its OpenCL score of 180831 shows strong compute performance for general GPU workloads. Its Vulkan score of 170774 indicates solid cross-platform graphics capability. The Passmark G3D score of 27212 places it well above the typical range for integrated graphics, and the GPU compute score of 12347 reinforces its compute strengths.

The RTX 4090 Mobile also wins on raw specification counts: more shading units (9728 vs 6144), more TMUs (304 vs 192), more ROPs (112 vs 96), higher texture rate (515.3 GTexel/s vs 384.0 GTexel/s), higher FP32 (32.98 vs 24.58 TFLOPS), and higher memory bandwidth (576.0 vs 432.0 GB/s). Its 16 GB memory capacity exceeds the LX 7G100’s 12 GB, and its 256-bit bus is wider than 192-bit.

The LX 7G100 has two specification wins. Its pixel rate is 192.0 GPixel/s versus 189.8 GPixel/s for the RTX 4090 Mobile, a marginal 1% advantage. Its FP16 throughput is 49.15 TFLOPS versus 32.98 TFLOPS, a 49% advantage in FP16 compute. The LX 7G100 also has a 2:1 FP16 ratio, which suggests it can process FP16 workloads at roughly twice the rate of FP32, while the RTX 4090 Mobile runs FP16 at a 1:1 ratio.

For physical installation, the LX 7G100 is a dual-slot card with four DisplayPort 1.4a outputs and a 294 mm length, making it suitable for desktop chassis with standard PCIe slots. The RTX 4090 Mobile is an IGP with portable device dependent outputs, meaning it is designed for laptops or mobile workstations.

The database shows the RTX 4090 Mobile in the 84th percentile of all GPUs, while the LX 7G100 sits at the 50th percentile with no measured data. The RTX 4090 Mobile’s nearest rivals all fall within a narrow range around 43262 to 44075 average score, confirming it competes at a specific performance tier. The LX 7G100 has no comparable data points.

For users prioritizing verified performance, mobile form factor, and ray tracing support, the RTX 4090 Mobile is the only option with evidence. For users needing a desktop card with FP16-heavy compute and multiple DisplayPort outputs, the LX 7G100 offers those specifications, but the lack of benchmark data means its actual performance remains unverified. The recorded data favors the RTX 4090 Mobile across every test category, while the LX 7G100’s advantages are limited to two specification values and a physical form factor.
