Both phones are powered by Qualcomm’s Snapdragon 8 Elite Gen 5 – a 3nm flagship chip that offers significant performance and increased power efficiency. This means that in real-world usage – multitasking, gaming and productivity – you’re likely to see similar raw compute power on both devices.
Camera Features
OnePlus 15: Triple 50MP rear cameras – main sensor, ultra-wide and telephoto – plus a 32MP front-facing camera. It relies on OnePlus’s in-house processing engine for image optimization.
Realme GT8 Pro: Offers a more ambitious triple-lens setup: a 50MP Ricoh GR-tuned main sensor, another 50MP ultra-wide, and a 200MP telephoto lens with 120× digital zoom. It also supports creative imaging modes and film-style tone options.
For video, the Realme supports high-frame-rate capture and improved processing, though real-world low-light performance remains to be seen.
Battery and Charging

Charging is fast on both fronts: the OnePlus supports 50W wireless charging and 120W wireless charging. The Realme tops the list with 120W wired speed and also supports 50W wireless charging.
In practice, the OnePlus’s larger battery and more efficient chip offer slightly better endurance, especially under heavy usage.
