Both are Kirin 9000 series, using the same architecture and manufacturing process. However, the 9000e is manufactured by TSMC, while the Kirin 9000l is manufactured by Samsung.
In terms of cpu, the 9000e is the same as the 9000, while the 9000l reduces the megacore 0.27Ghz frequency. In terms of gpu, the Kirin 9000 is the strongest, with 24 cores of gpu, the 9000e is 22 cores, and the 9000l has only 18 cores. Therefore, the Kirin 9000l is worse than the Kirin 9000e in terms of computing speed and image processing capacity.
