NVIDIA GeForce RTX 4080 Mobile vs Lisuan Tech LX ULTRA Comparison

Head-to-Head Benchmarks

The recorded data presents an unusual comparison: the NVIDIA GeForce RTX 4080 Mobile has a full set of benchmark scores, while the Lisuan Tech LX ULTRA has no recorded benchmark results. The average benchmark score for the RTX 4080 Mobile is 38,135, placing it in the 81st percentile of all GPUs in the database. The LX ULTRA holds a 50th percentile rating, but its average benchmark score is listed as 0, meaning no measured performance data exists for direct comparison.

Looking at the RTX 4080 Mobile’s individual results, the strongest showing comes in the Passmark G3D test with a score of 24,926. The Geekbench OpenCL result reaches 159,575, while the Vulkan test scores 145,807. Compute performance in the Passmark GPU compute test reaches 11,191. Legacy DirectX tests show 286 in DirectX 9, 244 in DirectX 11, 157 in DirectX 10, and 96 in DirectX 12. The Passmark G2D score is 929.

When comparing the RTX 4080 Mobile to its nearest rivals in the database, the data shows tight clustering. The NVIDIA GeForce MX570 posts an average score of 38,299, which is 0.4% higher than the RTX 4080 Mobile. The NVIDIA GeForce RTX 5080 Mobile scores 38,349, 0.6% higher. Both the NVIDIA GeForce RTX 4070 and the NVIDIA Tesla P4 score lower, at 37,648 and 37,628 respectively, each 1.3% behind the RTX 4080 Mobile. These deltas are small, indicating that the RTX 4080 Mobile sits in a competitive performance band rather than dominating or being dominated by its closest peers.

For the LX ULTRA, the absence of benchmark scores means no head-to-head wins can be assigned. The head-to-head benchmark list is empty, and the win counters for both items stand at zero. Any performance comparison must therefore rely on architectural specifications and theoretical throughput numbers, not measured results.

Architecture Differences

The two GPUs come from different design lineages. The NVIDIA GeForce RTX 4080 Mobile uses the AD104 chip based on Ada Lovelace architecture, fabricated on a 5 nm process at TSMC. The die contains 35,800 million transistors on a 294 mm² area, yielding a transistor density of 121.8 million per mm². The Lisuan Tech LX ULTRA uses the 7G105 chip with a TrueGPU architecture, produced on a 6 nm process, also at TSMC. Its transistor count and die size are listed as unknown, with no density figure available.

Memory configurations differ notably. The RTX 4080 Mobile has 12 GB of GDDR6 on a 192-bit bus, delivering 432.0 GB/s bandwidth. The LX ULTRA doubles the capacity to 24 GB of GDDR6, also on a 192-bit bus with the same 432.0 GB/s bandwidth. Both run memory at 2250 MHz with 18 Gbps effective speed. The bandwidth is identical, but the LX ULTRA offers twice the memory capacity.

Shader resources show a different distribution. The RTX 4080 Mobile carries 7,424 shading units, 232 texture mapping units, and 80 ROPs. The LX ULTRA has fewer shading units at 6,144, fewer TMUs at 192, but more ROPs at 96. Ray tracing cores exist only on the RTX 4080 Mobile, with 58 dedicated RT cores and 232 tensor cores. The LX ULTRA lists no RT cores and no tensor cores, indicating a different feature focus.

Theoretical throughput numbers are close. The RTX 4080 Mobile reaches 24.72 TFLOPS FP32 and 24.72 TFLOPS FP16 (1:1 ratio). The LX ULTRA achieves 24.58 TFLOPS FP32 and 49.15 TFLOPS FP16 (2:1 ratio). The FP32 figures are nearly identical, but the LX ULTRA doubles its FP16 throughput, suggesting a different compute path for half-precision workloads. Pixel and texture rates also align closely: the RTX 4080 Mobile delivers 133.2 GPixel/s and 386.3 GTexel/s, while the LX ULTRA posts 192.0 GPixel/s and 384.0 GTexel/s. The LX ULTRA has a higher pixel rate due to its larger ROP count, while the texture rate is essentially equal.

Power and physical specifications diverge sharply. The RTX 4080 Mobile has a TDP of 110 W, uses an integrated graphics processor form factor (IGP), and requires no power connectors. The LX ULTRA draws 225 W, uses a dual-slot design, needs a single 16-pin power connector, and suggests a 550 W power supply. The LX ULTRA measures 268 mm in length, 112 mm in height, and 40 mm in width. The RTX 4080 Mobile has no listed dimensions. Both use PCIe 4.0 x16 interfaces. Display outputs differ: the RTX 4080 Mobile is portable device dependent, while the LX ULTRA provides 4x DisplayPort 1.4a.

API support shows minor differences. Both support DirectX 12 Ultimate (12_2) and OpenGL 4.6. The RTX 4080 Mobile supports Vulkan 1.4, while the LX ULTRA supports Vulkan 1.3. The RTX 4080 Mobile was released on 2023-01-02, with a predecessor in GeForce 30 Mobile and a successor in GeForce 50 Mobile. The LX ULTRA has a release date of 2026-03-16 and lists no predecessor or successor. Both are marked as Active in production status.

The Verdict

The data presents a clear split. For anyone requiring measured performance evidence, the NVIDIA GeForce RTX 4080 Mobile is the only option with recorded benchmarks. Its 81st percentile standing, average score of 38,135, and close positioning against rivals like the GeForce RTX 5080 Mobile (0.6% higher) and GeForce RTX 4070 (1.3% lower) provide concrete reference points. The LX ULTRA has no benchmark scores, placing it at a 50th percentile with a zero average score, so its actual performance cannot be verified from the database.

The LX ULTRA offers advantages in specific specification areas. Its 24 GB memory capacity is double the RTX 4080 Mobile’s 12 GB, which matters for workloads that exceed 12 GB. Its FP16 throughput of 49.15 TFLOPS is double the RTX 4080 Mobile’s 24.72 TFLOPS, and its pixel rate of 192.0 GPixel/s is higher. But these are theoretical numbers, not measured results.

The RTX 4080 Mobile counters with ray tracing cores (58 RT cores) and tensor cores (232), which the LX ULTRA lacks entirely. It also draws 110 W versus 225 W, making it far more power-efficient on paper. The RTX 4080 Mobile’s smaller form factor, IGP slot width, and no power connector requirement position it for mobile integration, while the LX ULTRA is a dual-slot desktop card.

The verdict depends on what the data can support. The RTX 4080 Mobile has verifiable performance data and a clear position among rivals. The LX ULTRA has capacity and theoretical compute advantages, but no measured scores to confirm them. The database records no head-to-head wins for either side.
