NVIDIA GeForce RTX 4050 Mobile vs Lisuan Tech LX ULTRA Comparison

Where Each One Wins

The benchmark database presents a stark contrast between these two GPUs. The NVIDIA GeForce RTX 4050 Mobile is a fully characterized mobile part with nine recorded benchmark scores, while the Lisuan Tech LX ULTRA has zero recorded benchmarks, an average score of zero, and no rival comparisons. This means the data cannot show where the LX ULTRA wins; it can only show where the RTX 4050 Mobile delivers measurable results. The RTX 4050 Mobile holds a percentile rank of 63 against all GPUs, placing it above the median, while the LX ULTRA sits at the 50th percentile with no empirical backing.

The RTX 4050 Mobile wins in every category where data exists. Its strongest absolute result is the Geekbench Vulkan score of 75,235, slightly ahead of its OpenCL score of 74,748. In Passmark tests, the G3D score of 14,423 dominates the compute score of 5,947, indicating that the GPU is far more adept at rasterized graphics workloads than at general-purpose compute. The DirectX 9 score of 184 is the highest among the older API tests, while DirectX 11 scores 130, DirectX 10 scores 79, and DirectX 12 scores 61. The G2D score of 633 shows modest 2D performance relative to the 3D results.

The LX ULTRA, despite its larger hardware specifications, cannot claim any benchmark win because no measurements exist. The database records its average benchmark score as 0, and its percentile rank of 50 is a default value rather than a derived statistic. The data indicates that the LX ULTRA is essentially unverified, which is a significant disadvantage for any comparison. For users who rely on measured performance, the RTX 4050 Mobile is the only option with demonstrated capability.

Architecture Differences

The architectural gap between these two GPUs is substantial and extends to nearly every fundamental component. The RTX 4050 Mobile uses the AD107 chip built on TSMC's 5 nm process, while the LX ULTRA uses the 7G105 chip on TSMC's 6 nm process. The RTX 4050 Mobile's transistor count is recorded as 18,900 million on a die size of 159 mm², giving a transistor density of 118.9 million per square millimeter. The LX ULTRA's transistor count and die size are both listed as unknown, so no density figure can be calculated.

The RTX 4050 Mobile is based on the Ada Lovelace architecture, part of the GeForce 40-series, and belongs to the GeForce 40 Mobile generation. The LX ULTRA uses a "TrueGPU" architecture from the 7G100 generation, with no series or codename recorded. The RTX 4050 Mobile's predecessor is the GeForce 30 Mobile, and its successor is the GeForce 50 Mobile. The LX ULTRA has no recorded predecessor or successor.

The RTX 4050 Mobile includes 20 RT cores and 80 tensor cores, both of which are absent from the LX ULTRA's specification sheet, where they are listed as null. The RTX 4050 Mobile supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The LX ULTRA also supports DirectX 12 Ultimate (12_2) and OpenGL 4.6, but only Vulkan 1.3, one version behind. The LX ULTRA uses a PCIe 4.0 x16 interface, while the RTX 4050 Mobile uses PCIe 4.0 x8, which halves the available bus bandwidth for the mobile part.

Power delivery differs sharply. The RTX 4050 Mobile has a TDP of 50 W, uses no power connectors, and is designed as an IGP (integrated graphics processor) with a slot width of IGP. The LX ULTRA has a TDP of 225 W, requires a single 16-pin power connector, suggests a 550 W power supply, and occupies a dual-slot form factor with dimensions of 268 mm in length, 112 mm in height, and 40 mm in width. The RTX 4050 Mobile's display outputs are listed as "Portable Device Dependent," while the LX ULTRA provides four DisplayPort 1.4a outputs.

Head-to-Head Benchmarks

Since the head-to-head benchmark array is empty and the LX ULTRA has no recorded scores, a direct comparison of test results is impossible. Instead, the data allows an individual assessment of the RTX 4050 Mobile's performance against its nearest rivals, which provides context for its capabilities.

The RTX 4050 Mobile's average benchmark score is 19,049. Its nearest rival, the AMD Radeon RX 6600, scores 19,036, a delta of 0.1 percent, meaning the RTX 4050 Mobile is effectively tied with it. The NVIDIA Quadro K6000 also scores 19,030, another 0.1 percent delta. The NVIDIA Tesla K20m scores 19,089, which is 0.2 percent higher than the RTX 4050 Mobile, making it the only rival ahead. The NVIDIA RTX 2000 Ada Generation scores 18,954, a 0.5 percent delta in favor of the RTX 4050 Mobile.

These deltas are all within one percent, indicating that the RTX 4050 Mobile performs in a tightly clustered band around the 19,000 average score mark. The data shows that the RTX 4050 Mobile is not a performance outlier; it sits squarely among established GPUs from both AMD and NVIDIA. The RTX 4050 Mobile's percentile rank of 63 means it outperforms 63 percent of all GPUs in the database, which is a solid but not exceptional position.

For the LX ULTRA, the absence of benchmarks means there is no score to compare, no delta to compute, and no percentile rank derived from measurement. The database lists its percentile as 50 and its average score as 0, but these are placeholders rather than results. The LX ULTRA's hardware specifications suggest high theoretical capability, such as 24.58 TFLOPS FP32 and 432.0 GB/s memory bandwidth, but the data does not verify whether these translate into actual performance.

The Verdict

The data leads to one clear conclusion: the NVIDIA GeForce RTX 4050 Mobile is the only GPU of the two with measured, verified performance. Its benchmark scores, percentile rank of 63, and rival comparisons all come from recorded data. The Lisuan Tech LX ULTRA has no benchmarks, no average score, and no rival comparisons, making it impossible to recommend based on evidence.

The RTX 4050 Mobile is suitable for users who need a mobile GPU with confirmed results across multiple APIs and workloads. Its Geekbench Vulkan score of 75,235 and OpenCL score of 74,748 indicate strong compute and graphics capability for a 50 W part. Its Passmark G3D score of 14,423 confirms solid 3D rendering performance, while its G2D score of 633 is modest. The GPU sits within 0.5 percent of its nearest rivals, including the AMD Radeon RX 6600, which validates its positioning.

The LX ULTRA, based purely on the data, is an unverified product. Its specifications are impressive on paper: 24 GB of GDDR6 memory, 6,144 shading units, 192 texture mapping units, 96 ROPs, and 24.58 TFLOPS FP32. Its memory bandwidth of 432.0 GB/s is more than double the RTX 4050 Mobile's 192.0 GB/s. However, without any benchmark scores, these numbers cannot be confirmed to deliver real-world performance. The database shows no evidence of its behavior under load, its thermal characteristics, or its compatibility with existing software.

Users who require a verified GPU with a known performance profile should choose the RTX 4050 Mobile. Users who are considering the LX ULTRA must accept that the data provides no evidence of its performance, and the 225 W TDP, dual-slot size, and 16-pin power connector suggest a desktop-oriented card. The RTX 4050 Mobile's 50 W TDP and IGP form factor make it a low-power option, while the LX ULTRA demands a 550 W power supply. The choice is clear from the data: verified performance beats unverified specifications.
