The realme P4x 5G prioritizes a larger stated battery, faster rated charging and a 144Hz display; the Nothing Phone (4b) offers a Super AMOLED screen, an ultrawide rear camera and longer reported software support. A 2026 91mobiles comparison page showed ₹26,999 for the P4x and ₹35,999 for the Phone (4b)—a ₹9,000 difference in that Flipkart-associated price snapshot, not a guaranteed current price.

Which phone has the better display?
Choose the Nothing Phone (4b) if you value an AMOLED panel: its listed 6.77-inch Super AMOLED screen is slightly larger than the P4x’s 6.72-inch LCD. The P4x has the higher listed refresh rate at 144Hz versus 120Hz. That number alone does not establish which screen looks better; panel type, content and personal preference matter.

How do their cameras compare?
Both phones are listed with a 50MP main rear camera. The Nothing Phone (4b) adds an 8MP ultrawide camera, while the P4x’s listed secondary camera is a 2MP monochrome unit. The front-camera specifications are 16MP for Nothing and 8MP for realme. Megapixel counts and camera configurations do not demonstrate image quality, and no controlled photo comparison establishes a clear winner.
Which phone is faster?
The comparison lists a MediaTek Dimensity 7400 Ultra in the P4x, with realme stating a 2.6GHz peak, and a Snapdragon 6 Gen 4 in the Phone (4b), listed at up to 2.3GHz. Peak clock speed is not enough to determine gaming performance, everyday responsiveness or sustained speed. A reliable performance verdict would require comparable tests of both phones.
What is the price difference?
In the 91mobiles comparison page’s 2026 snapshot, the P4x was listed at ₹26,999 and the Phone (4b) at ₹35,999, both associated with Flipkart. That is a ₹9,000 gap in that snapshot—not a live quote, market average or Amazon price. Before buying, check the current checkout total, seller, offers and exact RAM and storage variant.
