The Apple iPhone 17 Pro Max and Vivo iQOO 15 differ notably in their performance specs. The iPhone has an internal storage of 2048GB, double that of the iQOO 15’s 1024GB. The iPhone is equipped with 12GB of RAM, while the iQOO 15 offers 16GB, giving the Vivo device a slight edge in memory capacity. Both phones feature a 3 nm semiconductor size and use big.LITTLE technology in their CPUs, but the iPhone’s Apple A19 Pro chipset is paired with a 6-thread CPU running at 4.26 GHz (for two cores) and 2.51 GHz (for four cores). In comparison, the iQOO 15’s Qualcomm Snapdragon 8 Elite Gen 5 chipset has an 8-thread CPU running at 4.6 GHz (for two cores) and 3.62 GHz (for six cores).
The iPhone 17 Pro Max achieves an AnTuTu benchmark score of 2,885,786, while the iQOO 15 outperforms it with a score of 4,030,245. In Geekbench 6 results, the iPhone scores 10,223 (multi-core) and 3,933 (single-core), while the iQOO 15 scores 10,059 (multi-core) and 3,234 (single-core), showing that both devices are close in multi-core performance, but the iPhone has a higher single-core score.
For GPU performance, the iPhone has an Apple A18 GPU running at 1490 MHz, while the iQOO 15 has an Adreno 830 GPU clocked at 1200 MHz. The iQOO 15 also has a higher GPU shading unit count, with 1536 compared to the iPhone’s 128. Regarding memory, the iPhone uses 4800 MHz RAM speed, while the iQOO 15 uses 5300 MHz RAM speed. The iQOO 15 also supports ECC memory, which the iPhone does not, and has a maximum memory bandwidth of 85.1 GB/s, compared to the iPhone’s 78.8 GB/s. The TDP is slightly lower in the iQOO 15 at 8.2W compared to the iPhone’s 10W.
