The Narzo also lists a faster-refresh display and more memory/storage options. Both official specification pages list 45W charging. Prices vary by listing and date, so compare the same market and storage tier before buying.
Key differences at a glance
The specifications below come from realme pages for different markets: the C100X entry is from realme Italy and the Narzo entry is from realme India. They should not be treated as universal configurations; confirm the exact regional model and SKU offered to you.

Which one has 5G, and what does that mean?
On the cited regional specifications, the Narzo 100x 5G is the 5G choice; the C100X Italy specification does not support 5G NR. The Narzo’s India specification lists 5G bands, but real-world access still depends on the carrier, coverage, plan, and local network deployment. Realme notes that live-network functions depend on carrier network conditions and service deployment.
The chipset names also differ, but the available evidence is specification-level rather than independent performance testing. It does not establish how much faster one phone is in everyday use, gaming, or sustained workloads.

Display, storage, and camera differences
Refresh rate
Both cited models use HD+ LCD panels. The C100X specification lists a refresh rate up to 120 Hz, compared with up to 144 Hz for the Narzo. A higher maximum refresh rate can make supported motion appear smoother, but it is not a measure of resolution or a guarantee that every app or activity runs at that rate.
Memory and storage
The cited C100X configuration is 4GB RAM and 256GB storage, using LPDDR4X memory and eMMC 5.1 storage; the page also lists microSD support. The Narzo page lists three configurations, from 4GB + 128GB to 6GB + 256GB, with LPDDR4X and UFS 2.2 storage. These are market-specific listed options, not a promise that every configuration is sold in every country.

Cameras
Both specifications list a 50MP rear camera. The front camera is listed as 5MP on the C100X and 8MP on the Narzo. Megapixel counts alone do not establish photo quality, so these figures are useful for identifying the listed hardware, not for predicting which phone takes better pictures.
The Tool Desk
Outbyte Driver Updater FREEFix the driver behind crashes, sound loss and screen glitchesFind Drivers →Outbyte PC Repair FREEClear out junk files and repair common Windows errorsFree Scan →Battery capacity and charging: check the regional figure
The official Italy C100X page gives a typical battery capacity of 7,500 mAh; the official India Narzo page gives 8,000 mAh. A Gadgets Now comparison instead reports 8,000 mAh for both models, so the C100X capacity is inconsistent across the cited sources. Use the specification for the exact regional SKU you are considering rather than assuming one figure applies worldwide.

Both official specifications list 45W charging, though the Narzo page calls it 45W SUPERVOOC. The figures describe listed charging capability; they do not establish equal charging time under all conditions.
Price difference: India listings captured on October 7, 2026
Prices in the cited pages are snapshots, not guaranteed current or transaction prices. The realme Store India ranking page, accessed October 7, 2026, displayed ₹17,999 for the C100X and ₹20,499 for the Narzo 100x 5G—a ₹2,500 difference in that listing. A separate realme India comparison page displayed ₹20,999 for the Narzo. Gadgets Now showed third-party offer-price figures of ₹16,999 for the C100X and ₹22,999 for the Narzo; these were not verified transaction prices.

Because these sources disagree, check the live realme listing and the exact RAM/storage variant for your market at purchase time. The C100X specification used here is from Italy, while the quoted store prices are India listings; the price comparison does not establish a like-for-like price in another country.
Which phone should you choose?
- Choose the Narzo 100x 5G if 5G is a priority: it is the 5G model in the cited specifications and offers the higher stated refresh-rate ceiling and more listed RAM/storage configurations.
- Consider the C100X if its listed configuration and local price suit you: the cited page lists 4GB + 256GB, microSD support, and up to 45W charging, but its Italy specification is 4G-only.
- Compare the exact variants before deciding: the two specification sources are from different markets, and the India price snapshots do not establish the C100X’s price in Italy or another region.
- Check the box contents before buying accessories: the cited Narzo India package listing includes a charger, cable, and protective case, but contents can vary by retail market.
Realme’s C100X specification page cautions that specifications are subject to the actual product. Confirm local model details with the seller before ordering.
