The Verdict

The data presents two very different products. The RTX 4080 Mobile is a mobile-class GPU with a modest 110 W TDP, designed for portable devices, and it has a full set of recorded benchmark scores showing competitive performance against other GPUs. Its average score of 38,135 places it in the 81st percentile, with direct rivals like the MX570 and RTX 5080 Mobile scoring nearly identically within 0.6%.

The Lisuan Tech LX PRO is a desktop-style dual-slot card with a 225 W TDP, a 550 W suggested PSU, and 4x DisplayPort 1.4a outputs. It has no benchmark scores at all, so its actual performance is unmeasured in this database. However, its raw specifications indicate a different design philosophy: more memory (24 GB vs 12 GB), more ROPs (96 vs 80), and a higher pixel rate (192.0 vs 133.2 GPixel/s).

For anyone evaluating the RTX 4080 Mobile, the recorded data confirms it delivers performance on par with the MX570 and RTX 5080 Mobile, while slightly edging out the RTX 4070 and Tesla P4 by 1.3%. For the LX PRO, the absence of benchmark data means it cannot be ranked against any competitor; only its specifications can be analyzed. The choice between these two depends entirely on whether measured performance (RTX 4080 Mobile) or higher memory capacity and ROP count (LX PRO) matters more for the intended workload.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark comparisons between the RTX 4080 Mobile and the LX PRO. The headToHeadBenchmarks field is empty, and neither winsA nor winsB has a recorded value. However, the RTX 4080 Mobile has individual benchmark scores that provide context for its capabilities.

In Geekbench OpenCL, the RTX 4080 Mobile scores 159,575. In Geekbench Vulkan, it scores 145,807. PassMark results show a DirectX 10 score of 157, DirectX 11 score of 244, DirectX 12 score of 96, and DirectX 9 score of 286. The PassMark G2D score is 929, the G3D score is 24,926, and the GPU compute score is 11,191. These scores indicate a GPU that handles both compute and graphics workloads with balanced results.

The LX PRO has no recorded scores in any test, so no direct comparison of measured performance is possible. The only comparative analysis must rely on the specification differences, particularly the memory capacity, ROP count, and pixel rate advantages of the LX PRO versus the shading unit, TMU, and texture rate advantages of the RTX 4080 Mobile.

Specification Differences

The two GPUs differ significantly in their core specifications. The RTX 4080 Mobile uses the AD104 chip built on a 5 nm process at TSMC, with 35,800 million transistors on a 294 mm² die. The LX PRO uses the 7G105 chip on a 6 nm process also at TSMC, but its transistor count and die size are listed as unknown.

Memory configurations differ substantially: the RTX 4080 Mobile has 12 GB of GDDR6, while the LX PRO has 24 GB of GDDR6. Both use a 192-bit bus and deliver 432.0 GB/s bandwidth, with identical memory clocks of 2250 MHz (18 Gbps effective).

Compute resources show a split. The RTX 4080 Mobile has more shading units (7,424 vs 6,144), more TMUs (232 vs 192), and includes 58 RT cores and 232 tensor cores. The LX PRO has more ROPs (96 vs 80) and does not list RT or tensor cores. The pixel rate favors the LX PRO at 192.0 GPixel/s versus 133.2 GPixel/s, while the texture rate slightly favors the RTX 4080 Mobile at 386.3 GTexel/s versus 384.0 GTexel/s.

FP32 compute is nearly identical: 24.72 TFLOPS for the RTX 4080 Mobile and 24.58 TFLOPS for the LX PRO. FP16 performance differs by design, with the RTX 4080 Mobile delivering 24.72 TFLOPS at a 1:1 ratio and the LX PRO delivering 49.15 TFLOPS at a 2:1 ratio.

Power and physical specifications are strongly divergent. The RTX 4080 Mobile has a 110 W TDP, no power connectors, and an IGP slot width. The LX PRO has a 225 W TDP, one 16-pin power connector, a dual-slot width, and a suggested PSU of 550 W. The LX PRO measures 248 mm in length, 118 mm in height, and 48 mm in width, while the RTX 4080 Mobile has no listed dimensions.

Display outputs also differ: the RTX 4080 Mobile is described as "Portable Device Dependent," while the LX PRO provides 4x DisplayPort 1.4a. Both support PCIe 4.0 x16 and DirectX 12 Ultimate (12_2) and OpenGL 4.6. Vulkan support differs slightly, with the RTX 4080 Mobile at version 1.4 and the LX PRO at version 1.3.

Architecture Differences

The RTX 4080 Mobile belongs to the GeForce 40-series, built on NVIDIA's Ada Lovelace architecture. It uses the AD104 chip fabricated on a 5 nm process at TSMC, with a transistor density of 121.8M per mm². The architecture includes dedicated RT cores (58) and tensor cores (232), which are absent from the LX PRO's specification list. Ada Lovelace is designed for the GeForce 40 Mobile generation, with the predecessor being GeForce 30 Mobile and the successor being GeForce 50 Mobile.

The Lisuan Tech LX PRO belongs to the 7G100 generation and uses an architecture called "TrueGPU" with the 7G105 chip. It is fabricated on a 6 nm process at TSMC, but the transistor count and die size are not recorded. The architecture does not list RT cores or tensor cores, which suggests a different compute focus. Its FP16 performance of 49.15 TFLOPS at a 2:1 ratio indicates the architecture can process half-precision data at twice the FP32 rate, unlike the RTX 4080 Mobile which runs FP16 at a 1:1 ratio.

The memory architecture is similar in terms of bus width and bandwidth, but the LX PRO doubles the capacity to 24 GB. The ROP count is higher on the LX PRO (96 vs 80), which contributes to its higher pixel rate. The RTX 4080 Mobile compensates with more shading units and TMUs, resulting in a slightly higher texture rate. Both use GDDR6 memory and PCIe 4.0 x16 interfaces.

The production status for both is "Active," with the RTX 4080 Mobile released in January 2023 and the LX PRO dated March 2026. The LX PRO has no predecessor or successor listed.

Where Each One Wins

The RTX 4080 Mobile wins in measured performance. It has a complete set of benchmark scores across Geekbench and PassMark tests, with an average score of 38,135 and an 81st percentile ranking. It narrowly outperforms the RTX 4070 and Tesla P4 by 1.3% in average score. The mobile form factor, with its 110 W TDP and IGP design, makes it suitable for portable devices where power draw is constrained. Its 58 RT cores and 232 tensor cores give it dedicated hardware for ray tracing and AI workloads, which the LX PRO does not list.

The LX PRO wins in raw memory capacity, offering 24 GB versus 12 GB, which benefits workloads that require large datasets or high-resolution textures. Its pixel rate of 192.0 GPixel/s is 44% higher than the RTX 4080 Mobile's 133.2 GPixel/s, indicating stronger fill-rate performance for pixel-heavy rendering. The higher ROP count (96 vs 80) supports this advantage. The dual-slot card with 4x DisplayPort 1.4a outputs is designed for multi-monitor desktop setups, whereas the RTX 4080 Mobile depends on the portable device's display configuration.

The FP16 compute advantage belongs to the LX PRO, which delivers 49.15 TFLOPS at a 2:1 ratio, exactly double the RTX 4080 Mobile's 24.72 TFLOPS at a 1:1 ratio. This suggests the LX PRO can process half-precision workloads faster. However, the RTX 4080 Mobile matches or slightly exceeds the LX PRO in FP32 compute (24.72 vs 24.58 TFLOPS) and texture rate (386.3 vs 384.0 GTexel/s).

The RTX 4080 Mobile's release date of January 2023 means it has established drivers and software support, while the LX PRO's March 2026 date suggests a newer product. The RTX 4080 Mobile's 5 nm process node is smaller than the LX PRO's 6 nm node, which typically indicates higher transistor density, and indeed the RTX 4080 Mobile packs 35,800 million transistors on a 294 mm² die. The LX PRO's transistor count is unknown, so no density comparison is possible.

For users who rely on documented benchmark results, the RTX 4080 Mobile is the only one of the two with measured data. For users who need maximum memory capacity and pixel throughput, the LX PRO's specifications indicate advantages in those specific areas. The choice depends on whether verified performance or specific hardware capabilities take priority.
