What the manufacturer lists
Realme's European product page lists the Snapdragon 680 processor, 33W Dart charging, a 5,000mAh battery, a 50-megapixel main-camera system and a display supporting up to 90Hz. These describe the original Realme 9i, rather than every phone with a similar name or a later 5G variant.

The page's dynamic-RAM advertising combines physical memory with storage allocated to an expansion feature. That is not the same as installing an equivalent amount of physical RAM. Similarly, camera megapixels alone do not measure image quality, and a display's maximum refresh rate does not guarantee every app runs at that rate.
This is a guide to an older model's claims, not a current buying recommendation. Check the exact regional variant, software support, warranty and current price before comparing an available unit. The Quest Pro guide applies the same distinction between a product's original launch specifications and today's offer.
