NVIDIA GeForce RTX 5090 Mobile vs Lisuan Tech LX PRO Comparison

Head-to-Head Benchmarks

The recorded data shows a stark contrast between these two GPUs: the NVIDIA GeForce RTX 5090 Mobile has a full benchmark suite with measurable results, while the Lisuan Tech LX PRO has no benchmark scores recorded in the database. This absence of data for the LX PRO makes direct numerical comparison impossible, but the specifications and the RTX 5090 Mobile's performance percentiles provide a clear picture of expected relative standing.

The RTX 5090 Mobile posts an average benchmark score of 45,152 across its ten recorded tests. Its percentile ranking of 84 among all GPUs indicates it outperforms the vast majority of the database's tracked graphics cards. The strongest results come from compute-oriented workloads: the Geekbench OpenCL score reaches 201,834, while the Vulkan score is 198,405. In the 3DMark Steel Nomad DX12 test, the card delivers a score of 5,871. The Passmark suite shows a G3D score of 30,034 and a GPU compute score of 13,401, alongside legacy DirectX tests ranging from 138 (DX12) to 324 (DX9).

The nearest rivals in the database provide context for the RTX 5090 Mobile's positioning. The AMD Radeon Pro 5500 XT averages 45,384, which is 0.5% higher than the RTX 5090 Mobile's average, a negligible difference. The NVIDIA GeForce RTX 4070 Ti scores 44,795, putting it 0.8% behind the RTX 5090 Mobile. The Intel Arc A730M averages 45,592, or 1% ahead, while the NVIDIA RTX 5880 Ada Generation scores 45,972, leading by 1.8%. These margins are all within a narrow band, indicating that the RTX 5090 Mobile sits in a competitive cluster where small score variations separate cards.

For the LX PRO, the database records zero benchmark scores and an average score of zero, with a percentile rank of 50. This percentile suggests it sits at the median of all tracked GPUs, but without actual test results, that ranking cannot be verified against specific workloads. The LX PRO's theoretical compute figures, however, offer a basis for projection: its FP32 throughput is 24.58 TFLOPS compared to the RTX 5090 Mobile's 31.80 TFLOPS, a 22.7% deficit. In FP16, the LX PRO reaches 49.15 TFLOPS with a 2:1 ratio, while the RTX 5090 Mobile delivers 31.80 TFLOPS at a 1:1 ratio, meaning the LX PRO holds a 54.6% advantage in half-precision workloads if the architecture scales as specified.

The Verdict

The data supports a clear conclusion: the NVIDIA GeForce RTX 5090 Mobile is the more complete and verifiable product. It has ten recorded benchmark scores, a percentile rank of 84, and a demonstrated average score of 45,152. The Lisuan Tech LX PRO has no recorded benchmarks, no average score, and a percentile rank of 50 that cannot be substantiated with actual test data. For any application requiring confirmed performance, the RTX 5090 Mobile is the only choice backed by measurements.

The LX PRO's specification sheet does indicate strengths in specific areas, particularly FP16 compute and pixel throughput. Its pixel rate of 192.0 GPixel/s exceeds the RTX 5090 Mobile's 169.7 GPixel/s by 13.1%. The LX PRO also offers higher memory clock speeds at 2250 MHz (18 Gbps effective) versus 1750 MHz (28 Gbps effective) for the RTX 5090 Mobile, though the RTX 5090 Mobile compensates with a wider 256-bit bus and GDDR7 memory, achieving 896.0 GB/s bandwidth versus 432.0 GB/s for the LX PRO.

The RTX 5090 Mobile also demonstrates efficiency advantages. Its TDP is 95 W compared to the LX PRO's 225 W, a 130 W difference that has substantial implications for system integration. The RTX 5090 Mobile uses an integrated form factor (IGP) with no power connectors, while the LX PRO requires a dual-slot cooler and a single 16-pin power connector. The suggested power supply for the LX PRO is 550 W, which adds system-level requirements.

For users prioritizing verified performance, the RTX 5090 Mobile is the clear selection. For users who specifically need high FP16 throughput or maximum pixel fill rates, the LX PRO's specifications suggest potential advantages, but those advantages remain unconfirmed without benchmark data.

Architecture Differences

The two GPUs employ fundamentally different architectures. The NVIDIA GeForce RTX 5090 Mobile uses the Blackwell 2.0 architecture on the GB203 chip, fabricated on a 5 nm process at TSMC. The Lisuan Tech LX PRO uses the TrueGPU architecture on the 7G105 chip, fabricated on a 6 nm process, also at TSMC. The process node difference of 1 nm gives the RTX 5090 Mobile a density advantage, reflected in its transistor count of 45,600 million across a 378 mm² die, yielding a density of 120.6 million transistors per square millimeter. The LX PRO's transistor count and die size are listed as unknown, so no direct density comparison is possible.

The RTX 5090 Mobile integrates 10,496 shading units, 328 texture mapping units, and 112 render output units. It also includes 82 ray tracing cores and 328 tensor cores, providing dedicated hardware for both ray-traced rendering and AI acceleration. The LX PRO has 6,144 shading units, 192 TMUs, and 96 ROPs, but its ray tracing core and tensor core counts are not recorded in the database. This absence suggests either the architecture lacks these specialized units or the data was not captured.

The memory subsystems differ substantially. The RTX 5090 Mobile uses 24 GB of GDDR7 memory on a 256-bit bus, achieving a bandwidth of 896.0 GB/s. The LX PRO also has 24 GB, but uses GDDR6 on a 192-bit bus, resulting in 432.0 GB/s bandwidth. The RTX 5090 Mobile's bandwidth advantage is 464.0 GB/s, or 107.4% higher, which directly impacts memory-bound workloads such as high-resolution textures and large data sets.

API support shows minor differences: both support DirectX 12 Ultimate (12_2) and OpenGL 4.6, but the RTX 5090 Mobile supports Vulkan 1.4 while the LX PRO supports Vulkan 1.3. The RTX 5090 Mobile uses a PCIe 5.0 x16 interface, while the LX PRO uses PCIe 4.0 x16, offering half the interconnect bandwidth for data transfers between the GPU and system.

Where Each One Wins

The NVIDIA GeForce RTX 5090 Mobile wins in all verified performance categories because it is the only GPU with recorded benchmark data. Its average score of 45,152 and percentile rank of 84 confirm strong overall performance. The card also leads in FP32 compute (31.80 TFLOPS), memory bandwidth (896.0 GB/s), texture rate (496.9 GTexel/s), and shading unit count (10,496). Its 95 W TDP and integrated form factor make it suitable for compact systems without external power requirements.

The Lisuan Tech LX PRO wins in theoretical specifications where its architecture provides advantages. Its FP16 throughput of 49.15 TFLOPS is 54.6% higher than the RTX 5090 Mobile's 31.80 TFLOPS, making it potentially stronger for half-precision workloads such as certain AI inference tasks. Its pixel rate of 192.0 GPixel/s exceeds the RTX 5090 Mobile, suggesting faster fill-rate-bound rendering. The LX PRO also has a higher memory clock at 2250 MHz, though the RTX 5090 Mobile's wider bus and GDDR7 technology overcome this in total bandwidth.

For display connectivity, the LX PRO offers four DisplayPort 1.4a outputs, while the RTX 5090 Mobile's outputs are listed as portable device dependent, meaning the LX PRO is better suited for multi-monitor desktop configurations. The LX PRO's dual-slot design with a 248 mm length also indicates a desktop-oriented card, while the RTX 5090 Mobile is designed for laptop integration.

The RTX 5090 Mobile's Vulkan 1.4 support and PCIe 5.0 x16 interface give it advantages in API currency and interconnect bandwidth. The LX PRO's PCIe 4.0 x16 interface is one generation older, which may impact data transfer rates in bandwidth-sensitive scenarios.

In summary, the RTX 5090 Mobile is the superior choice for any workload requiring verified performance, efficiency, or ray tracing capability. The LX PRO's specifications suggest potential advantages in FP16 compute and pixel fill rate, but without benchmark confirmation, those advantages remain theoretical. Users with specific half-precision or fill-rate requirements might investigate the LX PRO further, but the absence of measured results limits confidence in its real-world performance.
