I wouldn't say the gap is closed. It's not bad as previous Intel modems but not Qualcomm quality. I had Pixel 2 went to iPhone XR(current phone). In between I also had other android phones (S9, G7 and Pixel 3) for testing purposes. When compared to iPhone XR, iPhone XR had slower speeds when compared to Qualcomm modems. Also if your carrier supports carrier aggregation then the speeds are noticeable. I had do live streams with tethering this summer and Intels modems are not fast as Qualcomm modems.
