The LX PRO has no recorded benchmark scores in the database, resulting in an average benchmark score of zero and a percentile rank of 50 versus the RTX 4070 Mobile's 73rd percentile.

Architecture Differences

The two GPUs represent fundamentally different design philosophies. The NVIDIA GeForce RTX 4070 Mobile is a mobile-class chip based on Ada Lovelace, using TSMC's 5 nm process with 22,900 million transistors on a 188 mm² die. This yields a transistor density of 121.8 million transistors per square millimeter. The Lisuan Tech LX PRO uses the TrueGPU architecture on TSMC's 6 nm process, with transistor count and die size listed as unknown in the database.

The RTX 4070 Mobile integrates 4608 shading units, 144 texture mapping units, and 48 raster operation units. It also includes 36 dedicated ray tracing cores and 144 tensor cores, features that support hardware-accelerated ray tracing and AI workloads. The LX PRO has a higher raw count of 6144 shading units, 192 TMUs, and 96 ROPs, but the database records no ray tracing cores or tensor cores for this chip.

Clock behavior differs significantly. The RTX 4070 Mobile has a base clock of 1395 MHz and a boost clock of 1695 MHz. The LX PRO has no base or boost clock listed in the database, leaving its operating frequency unspecified. The memory clocks differ as well: the RTX 4070 Mobile runs at 2000 MHz (16 Gbps effective), while the LX PRO runs at 2250 MHz (18 Gbps effective).

The bus interface also separates the two. The RTX 4070 Mobile uses PCIe 4.0 x8, while the LX PRO uses PCIe 4.0 x16, doubling the available bandwidth for host communication. The power delivery setup reflects their different roles: the RTX 4070 Mobile has no power connectors and a 115 W TDP, while the LX PRO requires a single 16-pin connector, has a 225 W TDP, and suggests a 550 W power supply.

The RTX 4070 Mobile is part of the GeForce 40-series with a known predecessor (GeForce 30 Mobile) and successor (GeForce 50 Mobile). The LX PRO belongs to the 7G100 generation, with no predecessor or successor listed. The RTX 4070 Mobile was released on January 2, 2023, while the LX PRO has a release date of March 16, 2026.

Where Each One Wins

The RTX 4070 Mobile is the only one of the two with recorded benchmark data. Its strengths lie in its established performance profile across multiple test suites. In Geekbench, it scores 109197 in OpenCL and 108367 in Vulkan, placing it in the 73rd percentile of all GPUs in the database. Its Passmark G3D score of 19587 and GPU compute score of 8399 indicate solid general-purpose and compute performance. The RTX 4070 Mobile also supports Vulkan 1.4, the newer API revision.

The LX PRO wins on raw specifications. Its 24 GB memory capacity is three times larger than the RTX 4070 Mobile's 8 GB, and its 432.0 GB/s bandwidth is 68.75% higher. The LX PRO also has more shading units (6144 versus 4608), more TMUs (192 versus 144), more ROPs (96 versus 48), and higher pixel and texture rates (192.0 GPixel/s versus 81.36 GPixel/s, and 384.0 GTexel/s versus 244.1 GTexel/s). Its FP32 throughput of 24.58 TFLOPS is 57.3% higher, and its FP16 throughput of 49.15 TFLOPS is more than triple the RTX 4070 Mobile's 15.62 TFLOPS.

The LX PRO also offers a wider PCIe interface (x16 versus x8), a dual-slot cooling design, and four DisplayPort 1.4a outputs, making it suitable for multi-monitor setups. The RTX 4070 Mobile's display outputs are listed as portable-device-dependent, meaning they vary by laptop implementation.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries between the RTX 4070 Mobile and the LX PRO. The RTX 4070 Mobile has its own benchmark suite with nine recorded scores, while the LX PRO has an empty benchmark array. This means no direct comparative measurements exist.

For the RTX 4070 Mobile, the recorded data shows a Geekbench OpenCL score of 109197 and a Geekbench Vulkan score of 108367, nearly identical results across the two API frameworks. In Passmark testing, the DirectX 9 score is 223, DirectX 10 is 116, DirectX 11 is 179, and DirectX 12 is 85. The G2D (2D graphics) score is 763, while the G3D (3D graphics) score is 19587. The GPU compute score is 8399.

The average benchmark score for the RTX 4070 Mobile is 27435. The nearest rivals in the database are the AMD Radeon RX 6700 XT with an average score of 27425 (0% delta), the NVIDIA GeForce RTX 3090 with 27565 (-0.5% delta), the NVIDIA RTX PRO 4000 Blackwell with 27135 (1.1% delta), and the AMD Radeon Pro Vega 20 with 27839 (-1.5% delta). These deltas show the RTX 4070 Mobile sits within 1.5% of desktop-class GPUs, an indication of strong mobile performance.

The LX PRO has a percentile rank of 50, which is lower than the RTX 4070 Mobile's 73, but this rank is based on zero recorded benchmark scores. The absence of data makes direct comparison impossible from measurements alone. What can be stated is the specification-level comparison, where the LX PRO holds clear advantages in memory capacity, bandwidth, shader count, and raw compute throughput.

The Verdict

The data presents two distinct profiles. The NVIDIA GeForce RTX 4070 Mobile is a measured, validated performer with a full suite of benchmark results. Its average score of 27435 places it alongside desktop GPUs like the Radeon RX 6700 XT and GeForce RTX 3090 in the database rankings. It delivers ray tracing cores and tensor cores, supports Vulkan 1.4, and is designed for integration into portable devices with a 115 W TDP.

The Lisuan Tech LX PRO is a specification-heavy card with no recorded benchmark scores. It offers 24 GB of memory, 432.0 GB/s of bandwidth, 6144 shading units, and 24.58 TFLOPS FP32 performance. Its 225 W TDP and dual-slot form factor indicate a desktop-oriented design. The lack of benchmark data means its real-world performance cannot be confirmed from the database.

For users who require validated performance data and proven compatibility with existing software ecosystems, the RTX 4070 Mobile is the only option with measurements to support its claims. Its 73rd percentile ranking and proximity to desktop-class rivals in average score suggest a capable mobile GPU.

For users who prioritize maximum memory capacity, highest raw throughput, and the ability to drive multiple DisplayPort outputs, the LX PRO offers the superior specification sheet. However, the absence of any recorded benchmark results means its actual performance remains unverified in the database. The choice comes down to verified results versus unmeasured potential.
