The realme C100X and realme Narzo 100x 5G are different phones, not alternate names for one model. In the cited specifications, the C100X is a 4G phone with a Unisoc T7250 processor, while the Narzo supports 5G and uses a MediaTek Dimensity 6300. The Narzo also specifies a faster 144 Hz display and UFS 2.2 storage. Both list 45W charging, but their official battery figures come from different regional pages. In an India store snapshot accessed on October 7, 2026, the C100X was listed at ₹17,999 and the Narzo at ₹20,499; those displayed prices may change.
How the C100X and Narzo 100x 5G differ
The most consequential difference is connectivity: the cited realme Italy specification page for the C100X does not support 5G NR, while realme India lists 5G bands for the Narzo 100x 5G. Their processors are different too. These are regional specification sources, so confirm the exact model and SKU offered where you plan to buy.

Which model is the better fit?
Choose the Narzo 100x 5G if you need 5G
Only the Narzo is listed with 5G support in the cited specifications. It also has the higher stated maximum refresh rate and more listed RAM/storage configurations. Those are specification differences, not proof of a particular real-world performance or image-quality advantage.

Consider the C100X if its specific configuration and price suit you
The cited C100X listing pairs 4GB RAM with 256GB of eMMC 5.1 storage. The Narzo offers 4GB or 6GB RAM and UFS 2.2 storage in the listed India configurations. Compare like-for-like retail-market SKUs rather than assuming the Italy C100X specification page describes every C100X sold elsewhere.
Both phones list a 50MP rear camera, but megapixel counts alone do not establish which camera takes better photos. The listed front-camera resolutions are 5MP for the C100X and 8MP for the Narzo.
Battery capacity and charging: check the regional figures
The official Italy C100X page lists a typical battery capacity of 7,500 mAh; realme India lists 8,000 mAh typical for the Narzo. A Gadgets Now comparison instead reports 8,000 mAh for both. Because the C100X figure conflicts, do not treat either number as universal across markets or SKUs. Verify the specification for the exact product being sold.
Both cited official specifications list 45W charging, although the Narzo page names it 45W SUPERVOOC. The Narzo India package listing includes a charger, USB data cable, and protective case; check the seller’s box contents before buying accessories separately.
