NVIDIA RTX 4000 SFF Ada Generation vs Lisuan Tech LX PRO Comparison

Head-to-Head Benchmarks

The recorded database entries for these two GPUs present an unusual comparison challenge. The NVIDIA RTX 4000 SFF Ada Generation carries two benchmark results, while the Lisuan Tech LX PRO has no recorded benchmark scores in the database. This absence of head-to-head data means direct performance comparisons must be derived from architectural specifications and the limited benchmark information available.

The RTX 4000 SFF Ada Generation achieves a Geekbench OpenCL score of 124,812 and a Geekbench Vulkan score of 109,364. These results place the card at the 95th percentile among all GPUs in the database, with an average benchmark score of 117,088. The LX PRO holds a 50th percentile ranking, though this figure is based on no recorded benchmark data and an average score of zero. The contrast between a 95th percentile placement and a 50th percentile placement is stark, but the latter value lacks supporting measurement data.

Comparing the two directly through the nearest rivals of the RTX 4000 SFF Ada Generation provides context for its standing. The NVIDIA GB10 averages 117,393, which is 0.3% ahead of the RTX 4000 SFF Ada Generation. The AMD Radeon PRO W7700 averages 118,976, a 1.6% advantage. The RTX 4000 SFF Ada Generation leads the NVIDIA Tesla V100 SXM2 16 GB by 2.4% (114,395 average) and the NVIDIA RTX A5500 Mobile by 2.8% (113,944 average). These margins are narrow, indicating the RTX 4000 SFF Ada Generation sits in a tightly contested performance band.

The LX PRO has no nearest rivals listed, no benchmark scores, and no average score. This means the database contains no measured evidence of its performance in any workload. Any comparison between the two cards must therefore rely on the theoretical specifications recorded for each, particularly shading units, texture units, raster operations pipelines, memory configuration, and clock rates.

Architecture Differences

The architectural divide between these two GPUs is substantial. The NVIDIA RTX 4000 SFF Ada Generation uses the AD104 chip built on the Ada Lovelace architecture, manufactured by TSMC on a 5 nm process.

These specifications suggest the LX PRO is designed for workloads that scale with raw compute and memory throughput.

The absence of benchmark data for the LX PRO is a decisive factor. The database records a 50th percentile ranking for the LX PRO, but with an average score of zero and no nearest rivals, this ranking carries no empirical weight. The RTX 4000 SFF Ada Generation's 95th percentile is backed by actual measurements. The LX PRO's higher clocked memory at 18 Gbps effective and larger 24 GB capacity may appeal to applications with explicit memory requirements, but no benchmark confirms that advantage in practice.

The architecture differences reinforce this divide. The RTX 4000 SFF Ada Generation includes ray tracing cores and tensor cores, which the LX PRO does not list, and supports Vulkan 1.4 versus the LX PRO's Vulkan 1.3. The RTX 4000 SFF Ada Generation also has documented transistor count and die size, while the LX PRO lists both as unknown. The 5 nm process node for the RTX 4000 SFF Ada Generation is more advanced than the 6 nm node for the LX PRO.

The verdict from the data is clear: the RTX 4000 SFF Ada Generation is the better-documented, better-measured, and more efficient card, with confirmed benchmark results and a high percentile ranking. The LX PRO offers superior theoretical specifications in compute and memory, but the database contains no evidence that these translate into real performance. Users who require verified performance should choose the RTX 4000 SFF Ada Generation. Users who value maximum specification headroom and can operate within a 225 W power envelope and 248 mm length may consider the LX PRO, but they do so without any benchmark confirmation.
