NVIDIA GeForce RTX 4070 Mobile vs Lisuan Tech LX ULTRA Comparison

# NVIDIA GeForce RTX 4070 Mobile vs Lisuan Tech LX ULTRA

The recorded data presents two fundamentally different GPU classes: the NVIDIA GeForce RTX 4070 Mobile is a laptop-class chip with substantial benchmark validation, while the Lisuan Tech LX ULTRA is a desktop card with no recorded benchmark scores, making direct performance comparison impossible from the database. Based strictly on available measurements, the RTX 4070 Mobile holds an average benchmark score of 27,435 and sits at the 73rd percentile among all GPUs, whereas the LX ULTRA has an average score of zero and a 50th percentile placement. The LX ULTRA does deliver higher raw specifications on paper, including 24 GB of GDDR6 memory, 24.58 TFLOPS FP32 compute, and a 432.0 GB/s memory bandwidth, but without benchmark data, its real-world performance cannot be verified. The RTX 4070 Mobile is the only unit with measurable performance evidence, while the LX ULTRA remains an unvalidated specification sheet.

The Verdict

The data clearly separates these two products by purpose and validation status. The NVIDIA GeForce RTX 4070 Mobile is the choice for users who need verified performance in a mobile form factor. It has nine recorded benchmark results, an average score of 27,435, and a 73rd percentile standing across all GPUs. Its closest rival in the database is the AMD Radeon RX 6700 XT with an average score of 27,425, a virtual tie at a 0% delta. The RTX 4070 Mobile also sits within 0.5% of the NVIDIA GeForce RTX 3090 (27,565) and is 1.1% ahead of the NVIDIA RTX PRO 4000 Blackwell (27,135). This places the mobile chip in the same performance class as high-end desktop cards from the previous generation.

The Lisuan Tech LX ULTRA, by contrast, has an empty benchmark record. Its average score is listed as zero, and it has no nearest rivals in the database. The 50th percentile figure is a default placement rather than a measured result. Users should treat the LX ULTRA's specifications as unconfirmed capabilities, not demonstrated performance. The card targets a different segment entirely: a dual-slot desktop unit with a 225 W TDP, 1x 16-pin power connector, and a suggested 550 W power supply. It requires a full desktop chassis, while the RTX 4070 Mobile is an integrated graphics package (IGP) with no power connectors and is described as "Portable Device Dependent" for display output.

The verdict from the data is straightforward: the RTX 4070 Mobile is a proven, measured product suitable for laptop deployments where confirmed performance matters. The LX ULTRA is an unverified desktop card whose true capabilities cannot be assessed from the database. Pick the RTX 4070 Mobile for validated results; the LX ULTRA remains a speculative option with no benchmark evidence.

Where Each One Wins

Based on recorded data, the NVIDIA GeForce RTX 4070 Mobile wins in every measurable category. It has confirmed benchmark scores across nine tests, an average score of 27,435, and a 73rd percentile ranking among all GPUs. It matches or slightly exceeds several high-end desktop rivals, including the Radeon RX 6700 XT and RTX 3090. Its 115 W TDP and IGP form factor make it suitable for laptops where power efficiency and space are constrained. The Vulkan 1.4 support and 1:1 FP16 ratio make it a balanced compute and graphics solution.

The Lisuan Tech LX ULTRA wins only on paper specifications. It offers 24 GB of GDDR6 memory, which is three times the RTX 4070 Mobile's 8 GB, and its 432.0 GB/s bandwidth is 68.75% higher. Its FP32 throughput of 24.58 TFLOPS is 57.4% higher, and its FP16 throughput of 49.15 TFLOPS is more than triple the RTX 4070 Mobile's 15.62 TFLOPS.
