The realme P4x is the stronger paper choice for a sharper screen and higher-tier listed chipset; the realme Narzo 90X offers faster rated charging and a slightly larger display. Both list a 7,000mAh typical battery and up to 144Hz refresh rate. For buyers in India, the right pick depends on those trade-offs and the price of the exact RAM and storage version being sold.

Which phone has the better display?
P4x: higher resolution
The P4x’s 1080 × 2400 FHD+ panel has substantially more pixels than the Narzo 90X’s 1570 × 720 HD+ panel. That gives the P4x the clearer specification advantage for fine text and detailed images. Both are LCDs and list a maximum 144Hz refresh rate.

Narzo 90X: larger panel and higher listed brightness
The Narzo 90X screen measures 6.8 inches, compared with 6.72 inches on the P4x. Its listed brightness figures are also higher: 975 nits typical normal brightness and 1,200 nits HBM, versus 800 nits and 1,000 nits HBM on the P4x. The specifications therefore do not make the P4x better in every display respect.
How do their processors compare?
The P4x lists a MediaTek Dimensity 7400 Ultra 5G, while the Narzo 90X lists a Dimensity 6300. The P4x has the higher-tier chip on paper, which makes its specifications more compelling for buyers prioritizing processing capability. This is a comparison of listed silicon only: no independent benchmark, gaming, or thermal test establishes how the phones perform against each other in real use.
Charging and battery: capacity is close, charging rates differ
Both phones list a 7,000mAh typical battery. Their rated capacities are slightly different: 6,830mAh for the P4x and 6,820mAh for the Narzo 90X. These figures do not establish equal battery life; a reliable endurance ranking would require comparable testing.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
The Narzo 90X supports up to 60W wired charging, against up to 45W for the P4x. Those are maximum rated charging powers, not promised charging times. Actual time to charge is not established by these specifications.

Camera specifications: similar main and front resolutions
Both list a 50MP main rear camera and an 8MP front camera. The P4x also lists a 2MP monochrome rear camera. Megapixel counts and camera count alone do not show which phone takes better photos; no comparative camera test is established here.
What is the price difference in India?
Available price figures are dated snapshots rather than guaranteed current checkout prices, and they do not all refer to confirmed matching variants or seller terms.

- Gadgets 360 listed the P4x at ₹23,473 at Amazon on 2 October 2026.
- Smartprix showed lowest-price snapshots of ₹21,498 for the Narzo 90X and ₹23,399 for the P4x on 7 October 2026.
- A Smartprix variant page dated 6 October 2026 listed the P4x 8GB/256GB at ₹20,499.
Because the figures come from different snapshots and configurations, subtracting them does not produce a definitive like-for-like price gap. Check the same RAM and storage configuration, seller, bank offers, and delivery location before deciding.
