NVIDIA GeForce RTX 4070 Max-Q vs Lisuan Tech LX MAX Comparison

Head-to-Head Benchmarks

The recorded data places these two GPUs in entirely different performance classes, despite both carrying the 50th percentile ranking among all GPUs in the database. The Lisuan Tech LX MAX dominates across every measurable compute and memory metric, while the NVIDIA GeForce RTX 4070 Max-Q is defined by its exceptionally low power envelope. The gap is not marginal; it is a chasm in raw throughput.

The most striking divergence appears in floating-point performance. The LX MAX delivers 24.58 TFLOPS of FP32 compute, which is more than double the 11.34 TFLOPS offered by the RTX 4070 Max-Q. In FP16 workloads, the separation widens further: the LX MAX reaches 49.15 TFLOPS with a 2:1 ratio, while the RTX 4070 Max-Q manages only 11.34 TFLOPS with a 1:1 ratio. This means the LX MAX processes half-precision math at over four times the rate of the NVIDIA part. For any workload that leverages FP16 acceleration, the LX MAX holds an overwhelming advantage.

Memory bandwidth tells a similar story. The LX MAX has a 192-bit bus paired with 12 GB of GDDR6 memory running at 2250 MHz (18 Gbps effective), yielding 432.0 GB/s of bandwidth. The RTX 4070 Max-Q uses a 128-bit bus with 8 GB of GDDR6 at 2000 MHz (16 Gbps effective), producing 256.0 GB/s. The LX MAX therefore moves data 68.75% faster than the RTX 4070 Max-Q. This bandwidth advantage directly impacts texture-heavy scenes and large dataset operations, where the LX MAX can feed its shading units with significantly more data per second.

Pixel and texture throughput reinforce the LX MAX's dominance. The LX MAX achieves 192.0 GPixel/s fill rate and 384.0 GTexel/s texture rate. The RTX 4070 Max-Q records 59.04 GPixel/s and 177.1 GTexel/s respectively. In pixel fill, the LX MAX is 3.25 times faster; in texture fill, it is roughly 2.17 times faster. The LX MAX also doubles the ROP count (96 vs 48) and increases TMUs from 144 to 192.

The shading unit count further separates the two. The LX MAX carries 6144 shading units versus 4608 on the RTX 4070 Max-Q, a 33% increase in raw shader count. The LX MAX also has 192 TMUs versus 144, and 96 ROPs versus 48. These structural differences translate directly into the throughput figures above.

However, the RTX 4070 Max-Q counters with architectural features the LX MAX lacks entirely. The NVIDIA part includes 36 dedicated ray tracing cores and 144 tensor cores, while the LX MAX lists no RT or tensor core count in the database. This means the RTX 4070 Max-Q has dedicated hardware for ray tracing and AI acceleration, whereas the LX MAX's capabilities in those areas are unspecified. For applications that explicitly leverage these fixed-function units, the RTX 4070 Max-Q has a functional advantage that raw compute figures do not capture.

The power disparity is the defining counterpoint. The RTX 4070 Max-Q operates at a 35 W TDP, while the LX MAX draws 225 W. This is a 6.43 times difference in thermal design power. The RTX 4070 Max-Q is an integrated graphics processor (IGP) with no power connectors and a portable-device-dependent display output. The LX MAX is a dual-slot discrete card requiring a single 16-pin connector and a 550 W recommended power supply. The RTX 4070 Max-Q achieves its performance within a power budget that is a fraction of the LX MAX's requirement.

The Verdict

The data presents a clear verdict: the Lisuan Tech LX MAX is the superior performer in absolute terms across every recorded compute and memory benchmark metric. It leads in FP32, FP16, pixel rate, texture rate, memory bandwidth, memory capacity, bus width, shading units, TMUs, and ROPs. The only areas where the RTX 4070 Max-Q claims advantage are dedicated ray tracing cores, tensor cores, and power efficiency. The RTX 4070 Max-Q uses 35 W versus 225 W, making it dramatically more power-efficient per watt, though the database does not provide a direct performance-per-watt score.

For users who need maximum raw throughput, the LX MAX is the unequivocal choice. Its 24.58 TFLOPS FP32 and 432.0 GB/s bandwidth place it in a different tier than the RTX 4070 Max-Q. The LX MAX also provides 12 GB of memory versus 8 GB, which matters for large textures and datasets. The RTX 4070 Max-Q cannot match these figures under any workload.

For users constrained by power or form factor, the RTX 4070 Max-Q is the only viable option. Its 35 W TDP and IGP form factor mean it can operate in portable devices without external power connectors. The LX MAX, at 225 W with a 550 W recommended PSU and dual-slot footprint, requires a desktop chassis with substantial power delivery. The RTX 4070 Max-Q also brings ray tracing and tensor cores, which the LX MAX does not list.

The verdict is not about which GPU is better overall; it is about which fits the intended use case. The LX MAX wins on performance. The RTX 4070 Max-Q wins on efficiency and specialized hardware. Neither part covers the other's strengths.

Where Each One Wins

The Lisuan Tech LX MAX wins in every scenario that demands raw compute throughput. This includes FP32-heavy workloads such as scientific simulation, data processing, and general-purpose GPU computing. Its 24.58 TFLOPS FP32 and 49.15 TFLOPS FP16 make it suitable for high-performance computing tasks where the RTX 4070 Max-Q's 11.34 TFLOPS in both precisions would be a bottleneck. The LX MAX also wins in memory-intensive applications, given its 432.0 GB/s bandwidth and 12 GB capacity versus 256.0 GB/s and 8 GB on the RTX 4070 Max-Q.

The LX MAX wins in high-resolution rendering and multi-output display setups. Its 4x DisplayPort 1.4a outputs and 192.0 GPixel/s fill rate support multiple high-resolution monitors with ease. The RTX 4070 Max-Q's display output is portable-device-dependent, meaning its connectivity is dictated by the host device rather than the GPU itself.

The NVIDIA GeForce RTX 4070 Max-Q wins in power-constrained environments. Its 35 W TDP allows deployment in thin-and-light laptops or compact portable devices where the 225 W LX MAX would be physically impossible to integrate. The RTX 4070 Max-Q also wins in ray-traced workloads due to its 36 dedicated RT cores, provided the software uses DirectX 12 Ultimate or Vulkan 1.4 ray tracing features. The LX MAX has no listed RT core count, so its ray tracing performance is undefined in the database.

The RTX 4070 Max-Q wins in AI-accelerated tasks that leverage tensor cores. Its 144 tensor cores provide dedicated hardware for matrix operations common in machine learning inference and training. The LX MAX lists no tensor cores, so any AI workload would rely on its general-purpose FP16 or FP32 shaders, which may or may not be optimized depending on the software stack.

The LX MAX wins in texture-heavy workloads. Its 384.0 GTexel/s texture rate and 192 TMUs substantially outperform the RTX 4070 Max-Q's 177.1 GTexel/s and 144 TMUs. Games and applications that fill the screen with detailed textures will benefit from the LX MAX's higher texture throughput.
