NVIDIA GeForce RTX 5070 Mobile 12 GB vs Lisuan Tech LX PRO Comparison

Head-to-Head Benchmarks

The recorded data for both GPUs shows an empty benchmark comparison set, meaning no direct head-to-head scores were captured in this database entry. Both parts sit at the 50th percentile against all GPUs, and neither has an average benchmark score recorded. Without measured workloads, the quantitative comparison must rely entirely on the specification sheets.

The raw compute figures tell a clear story. The Lisuan Tech LX PRO delivers 24.58 TFLOPS of FP32 throughput, which is 87% higher than the 13.13 TFLOPS of the NVIDIA GeForce RTX 5070 Mobile. That is the single largest performance gap on paper. The LX PRO also reaches 49.15 TFLOPS in FP16 with a 2:1 ratio, while the RTX 5070 Mobile caps out at 13.13 TFLOPS with a 1:1 ratio. This means the LX PRO has a 3.74x advantage in half-precision workloads, which matters for AI inference and certain compute tasks.

Texture throughput follows the same pattern. The LX PRO processes 384.0 GTexel/s versus 205.2 GTexel/s for the RTX 5070 Mobile, an 87% lead. Pixel rate shows an even larger spread: 192.0 GPixel/s versus 68.40 GPixel/s, a 181% difference. The LX PRO's 96 ROPs versus 48 ROPs on the NVIDIA part explains the pixel rate gap, while the 192 TMUs versus 144 TMUs drive the texture rate advantage.

Memory bandwidth reverses the trend. The RTX 5070 Mobile uses GDDR7 at 24 Gbps effective on a 192-bit bus, yielding 576.0 GB/s. The LX PRO uses GDDR6 at 18 Gbps effective on the same 192-bit bus, yielding 432.0 GB/s. The NVIDIA part leads by 33% in bandwidth, which matters for memory-bound scenarios such as high-resolution textures or large dataset streaming. However, the LX PRO has 24 GB of VRAM versus 12 GB on the RTX 5070 Mobile, so capacity favors the Lisuan part by 2x even while speed favors NVIDIA.

Clock speeds are only partially listed. The RTX 5070 Mobile has a base clock of 907 MHz and a boost of 1425 MHz. The LX PRO has no base or boost clock recorded, so any frequency comparison is impossible from the database. The memory clock for the LX PRO is 2250 MHz, while the RTX 5070 Mobile runs at 1500 MHz, but the effective data rates (18 Gbps versus 24 Gbps) are what matter for bandwidth.

Where Each One Wins

The Lisuan Tech LX PRO wins decisively in raw compute throughput across every measured unit except memory bandwidth. FP32, FP16, texture rate, and pixel rate all favor the LX PRO by substantial margins. The 6144 shading units versus 4608 shading units, 192 TMUs versus 144 TMUs, and 96 ROPs versus 48 ROPs all stack in favor of the Lisuan part. For workloads that scale with shader count or fill rate, such as rasterization-heavy games at lower resolutions or GPU compute tasks, the LX PRO has the clear statistical advantage.

The RTX 5070 Mobile wins in memory bandwidth, delivering 576.0 GB/s versus 432.0 GB/s. This matters for scenarios where data movement dominates, such as 4K texture streaming, large physics simulations, or machine learning training with big batch sizes. The NVIDIA part also has dedicated RT cores (36) and tensor cores (144), which the LX PRO lacks entirely in the recorded data. The LX PRO lists no RT core or tensor core counts, so ray tracing acceleration and tensor-based features are either absent or unspecified. The RTX 5070 Mobile also supports Vulkan 1.4, while the LX PRO only reaches Vulkan 1.3, which could affect compatibility with the latest Vulkan-based titles or engines.

Power consumption flips the comparison completely. The RTX 5070 Mobile has a TDP of 50 W and uses no power connectors, fitting an integrated graphics package (IGP) form factor. The LX PRO draws 225 W, needs a 1x 16-pin connector, requires a 550 W suggested PSU, and occupies a dual-slot width. The NVIDIA part is designed for laptops or compact mobile systems where thermal and power budgets are tight. The LX PRO is a desktop add-in card with a 248 mm length, 118 mm height, and 48 mm width. Any system that can house the LX PRO will need serious cooling and power delivery, while the RTX 5070 Mobile can slot into a much thinner chassis.

The Verdict

The data points to two entirely different use cases. The Lisuan Tech LX PRO is the higher-performance part on paper in almost every compute metric. Its 24.58 TFLOPS FP32, 384.0 GTexel/s, and 192.0 GPixel/s are all far ahead of the RTX 5070 Mobile. The 24 GB VRAM capacity doubles the NVIDIA part's 12 GB, making the LX PRO suitable for large model loading or high-resolution asset work. Its 225 W TDP and dual-slot footprint are acceptable for a desktop workstation or high-end gaming rig.

The NVIDIA GeForce RTX 5070 Mobile is the efficient choice. Its 50 W TDP, IGP slot width, and lack of power connectors make it the only option for ultra-thin laptops or embedded systems. The 576.0 GB/s memory bandwidth exceeds the LX PRO despite having half the capacity, and the 36 RT cores plus 144 tensor cores provide hardware acceleration for ray tracing and AI workloads that the LX PRO cannot match. The 5 nm process node versus 6 nm also shows a density advantage, with 21,900 million transistors packed into 181 mm² compared to an unknown transistor count and die size for the LX PRO.

For a builder prioritizing raw throughput and VRAM capacity in a desktop, the LX PRO is the obvious pick from the recorded specifications. For a mobile system where power draw and physical size are constraints, the RTX 5070 Mobile is the only viable option. The 50th percentile ranking for both parts against all GPUs suggests they occupy similar overall performance tiers, but the profile of wins differs sharply. No benchmark scores exist to confirm real-world behavior, so the verdict rests entirely on the spec sheet.

Architecture Differences

The NVIDIA GeForce RTX 5070 Mobile uses the GB206 chip built on Blackwell 2.0 architecture, manufactured by TSMC on a 5 nm process. The chip contains 21,900 million transistors on a 181 mm² die, giving a transistor density of 121.0M per mm². It belongs to the GeForce 50-series and the GeForce 50 Mobile generation, with the GeForce 40 Mobile as its predecessor.

The Lisuan Tech LX PRO uses the 7G105 chip built on TrueGPU architecture, also from TSMC but on a 6 nm process. The transistor count and die size are not recorded in the database. It belongs to the 7G100 generation, with no predecessor listed. The manufacturer is listed as unknown.

The RTX 5070 Mobile integrates 36 RT cores and 144 tensor cores, providing dedicated hardware for ray tracing and tensor operations. The LX PRO shows no RT core or tensor core entries, indicating either their absence or lack of recorded data. This is a fundamental architectural difference: NVIDIA's Blackwell 2.0 is designed with hybrid rendering and AI acceleration in mind, while the TrueGPU architecture appears to focus purely on traditional shader-based throughput.

Process technology also differs. The 5 nm node on the RTX 5070 Mobile likely contributes to its 50 W TDP, while the 6 nm node on the LX PRO pairs with a 225 W TDP to reach higher clock-limited performance. The transistor density of 121.0M per mm² on the NVIDIA part suggests a very dense design, though the LX PRO's density is unknown.
