The single-core story firmly favors Apple: the iPhone 17 Pro Max's A19 Pro scores 3,933 in Geekbench 6 single-core versus 3,234 for the Xiaomi 17 Pro's Snapdragon 8 Elite Gen 5 — a ~21% lead that translates to snappier app launches, faster UI interactions, and superior performance in tasks that can't be parallelized. Multi-core scores, however, are nearly identical (~10,200 vs ~10,059), meaning sustained threaded workloads are a wash between the two chips.
Zoom out to the broader performance picture and the Xiaomi 17 Pro asserts itself in several meaningful ways. Its AnTuTu score of 3,691,009 eclipses the iPhone's 2,885,786 by a substantial margin — a gap driven in large part by a staggering 1,536 shading units on the Adreno 830 GPU versus just 128 on Apple's GPU, pointing to a massive raw graphics throughput advantage for the Xiaomi. It also carries more RAM (16 GB vs 12 GB, expandable to 24 GB), faster RAM at 5,300 MHz, higher memory bandwidth (85.1 GB/s), and supports ECC memory — collectively making it better equipped for heavy multitasking, large-model AI inference, and memory-intensive workloads. The Xiaomi's lower 8.2W TDP versus 10W also suggests it achieves this performance more efficiently.
On storage, the iPhone counters with up to 2,048 GB — double the Xiaomi's 1,024 GB ceiling — which is a decisive advantage for users who store large local libraries. Overall though, the Xiaomi 17 Pro holds the broader performance edge, particularly in GPU-heavy and multitasking scenarios, while the iPhone 17 Pro Max remains the faster device for single-threaded, latency-sensitive tasks.
