NVIDIA GeForce RTX 4080 Mobile vs Lisuan Tech LX 7G100 Comparison

The Verdict

The data presents a clear but asymmetric comparison. The NVIDIA GeForce RTX 4080 Mobile is a fully benchmarked, actively measured mobile GPU with a robust performance profile, while the Lisuan Tech LX 7G100 is a desktop card with no recorded benchmark scores in the database. The LX 7G100's average benchmark score is 0, and it holds no rival comparisons. The RTX 4080 Mobile, by contrast, has an average benchmark score of 38135 and sits at the 81st percentile among all GPUs.

For any user seeking verified performance data, the RTX 4080 Mobile is the only option with evidence. The LX 7G100 cannot be recommended based on measured results because none exist. However, the LX 7G100 does present a specification sheet that suggests a different design philosophy: it is a dual-slot desktop card with a 225 W TDP, a 1x 8-pin power connector, and a 550 W suggested PSU, whereas the RTX 4080 Mobile is an IGP (integrated graphics processor for laptops) with a 110 W TDP and no power connectors. The RTX 4080 Mobile uses the Ada Lovelace architecture on a 5 nm node; the LX 7G100 uses the TrueGPU architecture on a 6 nm node. The LX 7G100 has a higher pixel rate (192.0 GPixel/s vs 133.2 GPixel/s) and higher FP16 throughput (49.15 TFLOPS vs 24.72 TFLOPS), but the RTX 4080 Mobile counters with more shading units (7424 vs 6144), more TMUs (232 vs 192), and higher FP32 throughput (24.72 TFLOPS vs 24.58 TFLOPS). The verdict is straightforward: pick the RTX 4080 Mobile for verified performance, or the LX 7G100 only if raw specification sheet advantages in pixel rate and FP16 matter more than any measured data.

Architecture Differences

The RTX 4080 Mobile is built on the Ada Lovelace architecture using the AD104 chip, fabricated by TSMC on a 5 nm process node. It integrates 35,800 million transistors on a 294 mm² die, yielding a transistor density of 121.8M per mm². The architecture includes 58 ray tracing cores and 232 tensor cores, reflecting NVIDIA's dedicated hardware for RT and AI workloads. The FP16 throughput matches FP32 at 24.72 TFLOPS (1:1 ratio), indicating a design where half-precision does not double throughput. The production status is Active, with a release date of January 2, 2023, succeeding the GeForce 30 Mobile line and preceding the GeForce 50 Mobile line.

The LX 7G100 is based on the TrueGPU architecture with the 7G106 chip, also from TSMC but on a 6 nm process node. The transistor count and die size are recorded as unknown, and no transistor density is listed. The architecture does not list ray tracing cores or tensor cores. The FP16 throughput is 49.15 TFLOPS with a 2:1 ratio, meaning half-precision operations run at double the rate of FP32. The production status is Active, with a release date of June 17, 2026, and it has no predecessor or successor in the database.

The architectural split is stark: one is a mobile-focused, feature-rich NVIDIA design with RT and tensor hardware, the other is a newer, desktop-oriented chip with unknown transistor counts and no specialized core counts listed. The process node difference (5 nm vs 6 nm) gives the RTX 4080 Mobile a slight manufacturing advantage, but the LX 7G100 compensates with a higher FP16 rate and a higher pixel rate. The RTX 4080 Mobile's 232 tensor cores are a notable omission on the LX 7G100, which lists none.

Specification Differences

The two GPUs differ across nearly every major specification field, aside from memory configuration. Both have 12 GB GDDR6, a 192-bit bus, and 432.0 GB/s bandwidth, with identical memory clocks of 2250 MHz (18 Gbps effective). Beyond that, the differences are extensive.

The RTX 4080 Mobile uses the AD104 chip on a 5 nm TSMC process, with 35,800 million transistors and a 294 mm² die size.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries for these two GPUs. The winsA and winsB counters are both 0, and the headToHeadBenchmarks array is empty. Consequently, no direct comparative scores exist. However, the RTX 4080 Mobile has a full set of individual benchmark results, while the LX 7G100 has none.

The RTX 4080 Mobile's benchmark scores include a Geekbench OpenCL score of 159575 and a Geekbench Vulkan score of 145807. In Passmark tests, it scores 157 in DirectX 10, 244 in DirectX 11, 96 in DirectX 12, and 286 in DirectX 9. Its Passmark G2D score is 929, G3D score is 24926, and GPU compute score is 11191. The average benchmark score is 38135, placing it at the 81st percentile among all GPUs. Its nearest rivals in the database include the NVIDIA GeForce MX570 (avg score 38299, delta -0.4%), the NVIDIA GeForce RTX 5080 Mobile (avg score 38349, delta -0.6%), the NVIDIA GeForce RTX 4070 (avg score 37648, delta 1.3%), and the NVIDIA Tesla P4 (avg score 37628, delta 1.3%). These deltas indicate the RTX 4080 Mobile is within 0.6% of the MX570 and RTX 5080 Mobile, and about 1.3% ahead of the RTX 4070 and Tesla P4.

Since the LX 7G100 has no benchmark scores, its percentile is 50 (the default midpoint), and its average benchmark score is 0. The absence of data means the RTX 4080 Mobile's measured results cannot be directly compared to the LX 7G100's performance in any test. The only quantitative comparison possible is through specification-derived metrics, such as FP32 (24.72 vs 24.58 TFLOPS, a 0.6% edge for the RTX 4080 Mobile) and pixel rate (192.0 vs 133.2 GPixel/s, a 44% edge for the LX 7G100).

Where Each One Wins

The RTX 4080 Mobile wins in every category where measured performance exists. It has a verified average benchmark score of 38135, a 81st percentile ranking, and a full suite of Geekbench and Passmark results. Its shading unit advantage (7424 vs 6144) and TMU advantage (232 vs 192) likely contribute to its higher FP32 throughput (24.72 vs 24.58 TFLOPS), though the margin is slim. The RTX 4080 Mobile also supports Vulkan 1.4, a newer version than the LX 7G100's Vulkan 1.3. Its 110 W TDP and IGP form factor make it suitable for portable devices, with no external power connector required.

The LX 7G100 wins on specification-derived metrics that the RTX 4080 Mobile cannot match. Its pixel rate of 192.0 GPixel/s is 44% higher than the RTX 4080 Mobile's 133.2 GPixel/s, driven by its 96 ROPs vs 80. Its FP16 throughput of 49.15 TFLOPS is double the RTX 4080 Mobile's 24.72 TFLOPS, owing to the 2:1 FP16 ratio. The LX 7G100 also has more ROPs (96 vs 80) and a dual-slot desktop form factor with 4x DisplayPort 1.4a outputs, making it a fixed installation card. Its TDP of 225 W and 550 W suggested PSU indicate a higher power envelope for sustained desktop workloads.

In practical terms, the RTX 4080 Mobile is the choice for any application requiring verified benchmark scores, mobile deployment, or ray tracing and tensor core support. The LX 7G100 is the choice only for workloads that prioritize pixel fill rate or half-precision compute, and even then, its lack of recorded benchmarks means any advantage is purely theoretical. The database shows 0 wins for each in head-to-head tests, so the final split rests on the RTX 4080 Mobile's measured results versus the LX 7G100's unverified specifications.
