Based on the benchmarks which were initially posted on Clien, the A15 managed to score a peak performance of 198 FPS on the Manhattan 3.1 benchmark. However, subsequent tests saw it drop down to around 140-150 FPS. This seems like a massive dip, but as Tron notes in an older tweet, the A14 scored 120 FPS in the same benchmark, so even after the drop, it still outperforms the A14 by quite a considerable margin.
Apple A15 GPU peak benchmark test
Manhattan 3.1: 198 FPS (July unit sample)
However, after second round of test, throttling kicks in and drops to 140~150FPS.

Also, it should be noted that the benchmarks were apparently conducted in July based on a sample. This means that it hasn’t been optimized yet and we imagine that Apple has probably made further tweaks to improve and stabilize its performance since, so we’ll have to wait for the new iPhones to get a better idea of how well it will perform.
Apple has since confirmed that they will be hosting an event on the 14th of September where we will most likely see the new iPhone 13s and the Apple Watch Series 7 announced, so check back with us then for more updates.
