NVIDIA GeForce RTX 4080 Max-Q vs Lisuan Tech LX 7G100 Comparison

Head-to-Head Benchmarks

The database records no direct head-to-head benchmark scores for the NVIDIA GeForce RTX 4080 Max-Q and the Lisuan Tech LX 7G100. Both entries show an average benchmark score of zero and a percentile rank of 50 among all GPUs, with no nearest rivals listed. Consequently, the comparison rests entirely on the recorded specification data and derived performance metrics rather than measured application results.

The Lisuan Tech LX 7G100 holds the clear advantage in raw compute throughput. Its FP32 rating reaches 24.58 TFLOPS, which is 22.6% higher than the RTX 4080 Max-Q's 20.04 TFLOPS. The gap widens dramatically in FP16 workloads, where the LX 7G100 delivers 49.15 TFLOPS using a 2:1 ratio, versus the RTX 4080 Max-Q's 20.04 TFLOPS at a 1:1 ratio. That represents a 145% advantage for the Lisuan part in half-precision operations, a meaningful margin for workloads that leverage mixed-precision computing.

The Lisuan Tech LX 7G100 also leads in pixel throughput and texture throughput. Its pixel rate of 192.0 GPixel/s doubles the RTX 4080 Max-Q's 108.0 GPixel/s. Texture rate follows a similar pattern, with the LX 7G100 producing 384.0 GTexel/s against 313.2 GTexel/s for the NVIDIA part, a 22.6% lead. These differences stem from the Lisuan chip's higher ROP count (96 versus 80) and its elevated clock behavior, even though the RTX 4080 Max-Q has more shading units and TMUs.

The NVIDIA GeForce RTX 4080 Max-Q counters with architectural features absent from the Lisuan Tech LX 7G100 record. The RTX 4080 Max-Q includes 58 RT cores and 232 tensor cores, while the Lisuan part lists no RT cores and no tensor cores at all. This gives the NVIDIA GPU a decisive edge in ray-traced rendering and AI-accelerated workloads, assuming software support for those dedicated units. The RTX 4080 Max-Q also carries more shading units (7424 versus 6144, a 20.8% advantage) and more TMUs (232 versus 192, a 20.8% advantage), though the Lisuan part's higher clock rates compensate in aggregate throughput.

Memory configurations match exactly: both use 12 GB of GDDR6 on a 192-bit bus, with 432.0 GB/s bandwidth and 2250 MHz memory clock (18 Gbps effective). Neither side gains a memory advantage in capacity, bus width, or bandwidth.

Where Each One Wins

The Lisuan Tech LX 7G100 wins decisively in raw compute throughput and fill-rate-bound scenarios. Its FP32 performance of 24.58 TFLOPS exceeds the RTX 4080 Max-Q, and its FP16 output at 49.15 TFLOPS is more than double. This makes the LX 7G100 the stronger candidate for general-purpose compute, scientific simulations, and workloads that rely heavily on half-precision math, such as certain machine learning inference tasks. The doubling of pixel rate (192.0 GPixel/s) and the 22.6% texture rate advantage also favor the Lisuan part in rasterization-heavy scenes where pixel shading and texture sampling dominate. Its larger ROP count (96 versus 80) supports higher-resolution rendering with less bottlenecking.

The NVIDIA GeForce RTX 4080 Max-Q wins in features and efficiency. Its 58 RT cores provide dedicated hardware for ray-traced effects, a capability the Lisuan Tech LX 7G100 entirely lacks. The 232 tensor cores enable AI acceleration, which the Lisuan part cannot offer. The RTX 4080 Max-Q also operates at 60 W TDP compared to 225 W for the LX 7G100, making it far more suitable for thin-and-light portable devices. The NVIDIA GPU integrates as an IGP with no power connectors, while the Lisuan part is a dual-slot card requiring a 550 W power supply. In any scenario where power draw, physical size, or mobile integration matters, the RTX 4080 Max-Q holds the advantage.

The memory subsystem is a tie. Both GPUs ship with 12 GB of GDDR6 on a 192-bit interface, delivering 432.0 GB/s. Neither part offers a capacity or bandwidth edge, so memory-bound workloads will not differentiate between them.

Specification Differences

The two GPUs diverge across nearly every specification field. The RTX 4080 Max-Q uses a 5 nm process from TSMC, while the LX 7G100 uses a 6 nm process, also TSMC. The NVIDIA chip, AD104, packs 35,800 million transistors on a 294 mm² die, achieving a transistor density of 121.8 million per mm². The Lisuan chip, 7G106, has unknown transistor count and die size.

Clock behavior differs sharply. The RTX 4080 Max-Q lists a base clock of 795 MHz and a boost clock of 1350 MHz. The LX 7G100 lists no base or boost clocks, though its higher fill rates and FP32 output imply faster operating frequencies. Memory clocks match at 2250 MHz (18 Gbps effective).

Shading resources differ: the RTX 4080 Max-Q has 7424 shading units, 232 TMUs, and 80 ROPs. The LX 7G100 has 6144 shading units, 192 TMUs, and 96 ROPs. The RTX 4080 Max-Q adds 58 RT cores and 232 tensor cores; the LX 7G100 has none listed.

Power and physical design are opposites. The RTX 4080 Max-Q is a 60 W IGP with no power connectors. The LX 7G100 is a dual-slot card, 294 mm long, 120 mm tall, 49 mm wide, with a 225 W TDP, one 8-pin connector, and a 550 W suggested power supply. Display outputs also differ: the RTX 4080 Max-Q is portable-device dependent, while the LX 7G100 provides four DisplayPort 1.4a outputs.

API support is close but not identical. Both support DirectX 12 Ultimate and OpenGL 4.6. The RTX 4080 Max-Q supports Vulkan 1.4; the LX 7G100 supports Vulkan 1.3. The RTX 4080 Max-Q's FP16 runs at 1:1 ratio, while the LX 7G100 runs at 2:1, doubling its half-precision throughput.

Architecture Differences

The RTX 4080 Max-Q is built on NVIDIA's Ada Lovelace architecture, the GeForce 40 Mobile generation. It uses the AD104 chip manufactured on a 5 nm TSMC process. Ada Lovelace introduces dedicated RT cores (58 in this part) and tensor cores (232) for ray tracing and AI acceleration. The architecture also supports a 1:1 FP16 ratio, meaning FP16 and FP32 throughput are identical. The transistor count of 35,800 million on 294 mm² yields a density of 121.8 million transistors per square millimeter.

The Lisuan Tech LX 7G100 uses a proprietary TrueGPU architecture on the 7G106 chip, manufactured on a 6 nm TSMC process. TrueGPU includes no RT cores and no tensor cores, per the recorded data. Its FP16 execution runs at a 2:1 ratio, doubling half-precision output relative to FP32. The architecture favors raw throughput over specialized units, as shown by its higher FP32, pixel rate, and texture rate despite fewer shading units. Transistor count and die size remain unknown, so density comparisons are not possible.

The process node difference (5 nm versus 6 nm) likely contributes to the RTX 4080 Max-Q's lower power draw, though the architecture's efficiency features and the Max-Q design's 60 W TDP are the dominant factors. The LX 7G100's 225 W TDP suggests a design tuned for maximum compute output rather than power efficiency. The absence of RT and tensor cores in the LX 7G100 means it relies entirely on general-purpose shader execution, while the RTX 4080 Max-Q can offload specific workloads to dedicated hardware.

The Verdict

The data paints a clear split. The Lisuan Tech LX 7G100 is the stronger raw compute engine. Its FP32 output of 24.58 TFLOPS beats the RTX 4080 Max-Q by 22.6%, and its FP16 output of 49.15 TFLOPS is 145% higher. Fill rates follow suit: 192.0 GPixel/s versus 108.0 GPixel/s, and 384.0 GTexel/s versus 313.2 GTexel/s. For users who prioritize shader throughput, pixel processing, or half-precision math, the LX 7G100 is the superior part in every measured dimension.

The NVIDIA GeForce RTX 4080 Max-Q is the more feature-rich and efficient option. Its 58 RT cores and 232 tensor cores provide dedicated ray tracing and AI acceleration, capabilities the LX 7G100 lacks entirely. The RTX 4080 Max-Q operates at 60 W TDP with no external power connectors, while the LX 7G100 requires 225 W and a dual-slot chassis with a 550 W power supply. The NVIDIA part also supports Vulkan 1.4 versus 1.3 on the Lisuan part.

The choice hinges on workload and form factor. For a portable, power-constrained device where ray tracing, AI features, and low power draw are essential, the RTX 4080 Max-Q is the only viable option between these two. For a desktop or larger chassis where maximum compute throughput and fill rates matter and power is less constrained, the Lisuan Tech LX 7G100 delivers higher measured performance in FP32, FP16, pixel rate, and texture rate. The RTX 4080 Max-Q wins on features and efficiency; the LX 7G100 wins on speed and throughput. Neither GPU holds a memory advantage, as both provide identical 12 GB GDDR6 configurations with 432.0 GB/s bandwidth.
