NVIDIA RTX 4000 Mobile Ada Generation vs Lisuan Tech LX PRO Comparison

The Verdict

The data presents two very different solutions for GPU-accelerated work. The NVIDIA RTX 4000 Mobile Ada Generation is a 110 W integrated graphics processor built on a 5 nm TSMC process, designed to fit into a portable device. The Lisuan Tech LX PRO is a 225 W dual-slot desktop card on a 6 nm TSMC process with a 16-pin power connector and a 550 W suggested power supply. The LX PRO offers a 24 GB memory pool and a 2:1 FP16 ratio, while the RTX 4000 Mobile has a higher FP32 shading rate and more texture mapping units. Users who prioritize portability and lower power draw within a laptop form factor should select the RTX 4000 Mobile. Users who require double the memory capacity for large datasets and who have a desktop chassis with adequate power delivery should select the Lisuan Tech LX PRO.

Architecture Differences

The NVIDIA RTX 4000 Mobile Ada Generation uses the AD104 chip based on the Ada Lovelace architecture, manufactured by TSMC on a 5 nm process. The chip contains 35,800 million transistors on a die size of 294 mm², yielding a transistor density of 121.8M per mm². It is part of the GeForce 40-series and the Ada-MW generation. The architecture includes 58 RT cores and 232 tensor cores, features that the Lisuan Tech LX PRO lacks entirely, as its data sheet lists no RT cores and no tensor cores.

The Lisuan Tech LX PRO uses the 7G105 chip based on the TrueGPU architecture, manufactured by TSMC on a 6 nm process. The transistor count and die size are unknown. Its FP16 performance is 49.15 TFLOPS with a 2:1 ratio, meaning it can perform twice as many FP16 operations as FP32 operations. The NVIDIA chip has an FP16 rate of 24.72 TFLOPS with a 1:1 ratio, meaning FP16 and FP32 throughput are identical. This architectural difference indicates the LX PRO is tuned for workloads that benefit from half-precision math, while the RTX 4000 Mobile treats FP16 and FP32 as equal.

The RTX 4000 Mobile supports Vulkan 1.4, whereas the LX PRO supports Vulkan 1.3. Both GPUs support DirectX 12 Ultimate (12_2) and OpenGL 4.6. The production status for both is Active. The RTX 4000 Mobile was released on 2023-03-20, while the LX PRO has a release date of 2026-03-16. The RTX 4000 Mobile lists a predecessor of Ampere-MW and a successor of Blackwell-MW; the LX PRO lists no predecessor or successor.

Specification Differences

The two GPUs differ across nearly every core specification. The NVIDIA RTX 4000 Mobile has 7424 shading units, 232 TMUs, and 80 ROPs. The Lisuan Tech LX PRO has 6144 shading units, 192 TMUs, and 96 ROPs. The RTX 4000 Mobile has more shading units and TMUs, while the LX PRO has more ROPs.

Clock speeds differ significantly. The RTX 4000 Mobile has a base clock of 1290 MHz and a boost clock of 1665 MHz. The LX PRO has no base clock and no boost clock listed in the database. Both GPUs use a memory clock of 2250 MHz with 18 Gbps effective speed.

Memory capacity is the largest differentiator. The RTX 4000 Mobile has 12 GB of GDDR6 on a 192-bit bus with 432.0 GB/s bandwidth. The LX PRO has 24 GB of GDDR6 on the same 192-bit bus with the same 432.0 GB/s bandwidth. The bus width and bandwidth are identical, but the LX PRO holds twice the data.

Compute rates show a close FP32 race. The RTX 4000 Mobile delivers 24.72 TFLOPS FP32, while the LX PRO delivers 24.58 TFLOPS FP32. The LX PRO leads in pixel rate at 192.0 GPixel/s versus 133.2 GPixel/s for the RTX 4000 Mobile. Texture rates are nearly identical: 386.3 GTexel/s for the RTX 4000 Mobile and 384.0 GTexel/s for the LX PRO.

Power and physical design are completely different. The RTX 4000 Mobile has a 110 W TDP, is an IGP with no slot width, has no power connectors, and uses a PCIe 4.0 x16 interface. The LX PRO has a 225 W TDP, is dual-slot, uses a single 16-pin power connector, requires a 550 W suggested PSU, and also uses PCIe 4.0 x16. The RTX 4000 Mobile has display outputs that are portable device dependent. The LX PRO has 4x DisplayPort 1.4a outputs. The LX PRO measures 248 mm by 118 mm by 48 mm; the RTX 4000 Mobile has no listed dimensions.

Head-to-Head Benchmarks

The recorded data does not include any direct head-to-head benchmark scores, wins for either GPU, or nearest rivals. The analysis must rely on the specification-derived rates that are present in the database.

In FP32 compute, the NVIDIA RTX 4000 Mobile leads by a small margin. It delivers 24.72 TFLOPS against 24.58 TFLOPS for the Lisuan Tech LX PRO, a difference of 0.14 TFLOPS. This is a negligible gap in raw single-precision throughput, indicating that for standard FP32 rendering or compute workloads, the two GPUs will perform at a nearly identical level.

In FP16 compute, the Lisuan Tech LX PRO is decisively ahead. Its 49.15 TFLOPS FP16 rate is double its FP32 rate, while the RTX 4000 Mobile's FP16 rate is capped at 24.72 TFLOPS. The LX PRO offers 24.43 TFLOPS more FP16 throughput than the RTX 4000 Mobile. For any workload that uses half-precision arithmetic, such as certain AI inference or graphics passes, the LX PRO has a clear mathematical advantage.

In pixel fill rate, the LX PRO wins again. Its 192.0 GPixel/s is 58.8 GPixel/s higher than the 133.2 GPixel/s of the RTX 4000 Mobile. This indicates the LX PRO has a stronger ROP configuration, which is useful for high-resolution rendering with heavy overdraw or for driving multiple displays at high resolutions.

In texture fill rate, the two are nearly tied. The RTX 4000 Mobile posts 386.3 GTexel/s, just 2.3 GTexel/s ahead of the LX PRO's 384.0 GTexel/s. This suggests that texture-heavy workloads will see no meaningful difference between the two cards.

Memory bandwidth is identical at 432.0 GB/s for both. The RTX 4000 Mobile has 12 GB of capacity, while the LX PRO has 24 GB. With the same bandwidth, the LX PRO can hold a larger working set without needing to swap data, but the speed of data transfer is the same.

Where Each One Wins

The NVIDIA RTX 4000 Mobile Ada Generation wins in scenarios where its higher shading unit count and FP32 throughput matter most. With 7424 shading units and 24.72 TFLOPS FP32, it edges out the LX PRO in single-precision compute. Its higher texture rate of 386.3 GTexel/s also gives it a slight lead in texture-heavy workloads. The RTX 4000 Mobile includes 58 RT cores and 232 tensor cores, making it the only option of the two with dedicated hardware for ray tracing and tensor operations. Its 110 W TDP and IGP form factor mean it can operate inside a portable device without external power connectors. Users who need a mobile workstation GPU with ray tracing support and balanced FP32/FP16 performance should choose the RTX 4000 Mobile.

The Lisuan Tech LX PRO wins in memory capacity and half-precision compute. Its 24 GB GDDR6 pool is double the RTX 4000 Mobile's 12 GB, which is critical for large language models, big simulation grids, or multi-application workflows that exceed 12 GB. Its FP16 rate of 49.15 TFLOPS is roughly double that of the RTX 4000 Mobile, making it the better choice for FP16-intensive workloads. The LX PRO also leads in pixel rate at 192.0 GPixel/s and has 96 ROPs versus 80, giving it an edge in fill-rate-bound scenarios. Its 4x DisplayPort 1.4a outputs support multi-monitor desktop setups, whereas the RTX 4000 Mobile's outputs depend on the portable device. The LX PRO is a desktop card requiring a 550 W suggested PSU and a dual-slot chassis, so it is suited for stationary workstations where power and space are available.

The data shows a split decision. For portable use, ray tracing, and tensor-heavy workloads, the RTX 4000 Mobile is the only functional choice due to its form factor and dedicated cores. For stationary use with large memory requirements or FP16 compute, the LX PRO is the stronger performer on paper. Both GPUs sit at the 50th percentile against all GPUs in the database, and neither has an average benchmark score recorded.
