Intel Arc B580 vs Lisuan Tech LX ULTRA Comparison

The Verdict

The Intel Arc B580 and Lisuan Tech LX ULTRA occupy fundamentally different positions in the recorded benchmark database. The Arc B580 carries an average benchmark score of 23,021, placing it in the 68th percentile of all GPUs. The LX ULTRA has no recorded benchmark scores, an average of 0, and sits at the 50th percentile by default. The data shows that the Arc B580 is the only one of the two with measurable performance validation. The LX ULTRA presents a raw specification sheet that is impressive on paper, but without any benchmark results, its real-world standing cannot be quantified. For users who require verified performance data, the Arc B580 is the logical selection. For users who prioritize raw specifications such as 24 GB of memory and 24.58 TFLOPS of FP32 compute, the LX ULTRA is the specification leader, but it remains an unproven quantity in the database.
