Qualcomm's Adreno X2-90 GPU in the Snapdragon X2 Elite offers nearly double the theoretical compute throughput of its predecessor Adreno X1, with eight shader processors, higher clock speeds (1.85 GHz), and improved integer performance. The architecture emphasizes FP32 and FP16 operations but lacks FP64 support and hardware fused multiply-add capability, comparing competitively with AMD's integrated GPUs in laptops.
Apple's iPhone 18 Pro Max sold in the US continues to use Qualcomm's Snapdragon X80 modem, according to a TechInsights teardown, despite most other variants adopting Apple's in-house C2 modem. The discrepancy likely stems from contractual obligations, though Apple's C-series modems now match Qualcomm's capabilities with better power efficiency.
A teardown of the iPhone 18 Pro Max reveals it uses a Qualcomm Snapdragon SDX80M 5G modem instead of Apple's advertised C2 modem, but only in the US market. Apple's specification pages confirm the C2 is listed for the iPhone 18 Pro but omitted for the Pro Max in the US, while other markets show the C2 in both models. The discrepancy likely stems from Apple's 2023 agreement with Qualcomm.
