What the differences mean in everyday use
Display: sharper image or larger panel?
The P4x’s 1080 × 2400 FHD+ resolution is substantially higher than the Narzo 90X’s 1570 × 720 HD+ resolution. That gives the P4x the paper advantage for fine text and image detail. The Narzo 90X’s screen is slightly larger at 6.8 inches, compared with 6.72 inches, and its listed brightness figures are higher. Both are LCDs with a maximum 144Hz refresh rate; that maximum alone does not establish which screen looks better in every condition.
Quick wins for a faster PC:

The P4x lists a MediaTek Dimensity 7400 Ultra 5G, while the Narzo 90X lists a Dimensity 6300. On the specifications alone, the P4x has the stronger chipset. This is not a measured performance result: there is no comparable benchmark or game test here to establish actual speed, sustained performance, thermals, or gaming experience.

Charging and battery capacity
The Narzo 90X supports up to 60W wired charging, compared with up to 45W on the P4x. Those are maximum rated wattages, not promises of a particular charge time. Both list a 7,000mAh typical battery; their rated capacities are 6,830mAh for the P4x and 6,820mAh for the Narzo 90X. Similar listed capacity does not prove similar battery life without comparable endurance testing.
Cameras: compare results, not megapixel counts
Both phones list a 50MP main rear camera and an 8MP front camera. The P4x also lists a 2MP monochrome rear camera. These specifications do not establish which phone takes better photos or video.
Price difference in India
Price comparisons depend on the date, seller, and exact RAM and storage variant. The following figures are snapshots reported by secondary sources, not guaranteed current prices or a like-for-like price gap.
- Gadgets 360 listed the P4x at ₹23,473 at Amazon on 2 October 2026. See its P4x price page.
- Smartprix showed lowest-price snapshots of ₹21,498 for the Narzo 90X and ₹23,399 for the P4x on 7 October 2026. Its comparison page does not make those figures a guaranteed matching-variant, same-seller comparison.
- A separate Smartprix variant page listed the P4x 8GB/256GB at ₹20,499 on 6 October 2026. See the variant comparison.
Before buying, compare the same RAM and storage configuration, seller, bank offer, and delivery location. The snapshots above come from different dates and configurations, so subtracting one from another would not produce a dependable like-for-like price difference.

Which one should you buy?
- Choose the P4x on specifications if FHD+ resolution and the higher-tier listed chipset matter most to you.
- Consider the Narzo 90X if faster rated wired charging or its slightly larger display is more important.
- Decide by the actual offer only after matching RAM and storage and checking the seller’s current terms.
These trade-offs do not establish real-world superiority in gaming, camera quality, thermals, or battery life. Manufacturer specifications describe listed features; independent, comparable testing would be needed to rank those outcomes.
