The realme P4x 5G has the stronger display specifications and a higher-tier chipset on paper; the OPPO K14x 5G has a slightly larger screen and may cost less, depending on the variant and current offer. Both advertise a 50MP main camera, and their battery capacities differ, but neither spec sheet establishes which phone lasts longer or takes better photos in everyday use. For Indian buyers, compare the exact RAM/storage variants and checkout prices before deciding.

Which phone has better specifications?
Display: sharper and faster on the P4x, slightly larger on the K14x
realme specifies an FHD+ panel with a refresh rate of up to 144Hz. OPPO lists the K14x panel as HD+ at 1570 × 720 and up to 120Hz. That gives the P4x the higher resolution and maximum refresh-rate claims, while the K14x is marginally larger diagonally: OPPO’s 17.15cm measurement is about 6.75 inches, compared with realme’s 6.72 inches. The published figures do not establish brightness, color accuracy, or outdoor readability, so they cannot settle every aspect of display quality.
Performance: the chipset specifications favor the P4x
The manufacturers list a Dimensity 7400 Ultra in the P4x and a Dimensity 6300 in the K14x. The model names indicate different tiers, but they are not a substitute for a controlled head-to-head test. For additional context, 91mobiles reported Geekbench multi-core scores of 2,994 for the P4x and 1,869 for the K14x, plus AnTuTu scores of 974,831 and 565,613, respectively, on its comparison page accessed October 7, 2026. The page does not establish a controlled test protocol, so treat those as secondary-source figures rather than verified lab results.
There is also a different manufacturer figure: realme claims 780,000+ on AnTuTu for the P4x on its product page. Because the sources may use different test conditions, software, or configurations, these scores should not be combined as if they came from one comparable test. The useful takeaway is that realme lists the higher-tier chipset; the available figures do not establish a precise real-world performance gap.

Battery: larger stated capacity for realme, but no direct endurance comparison
realme advertises a 7000mAh battery and 45W charging. OPPO specifies 6500mAh typical capacity (6335mAh rated) and up to 45W SUPERVOOC charging. These are manufacturer specifications, not a direct runtime test; capacity alone cannot predict how long either phone will last for a particular user.
OPPO’s February 2, 2026 launch announcement reports up to 20.9 hours of screen-off calling, 17.6 hours of YouTube playback, 16.1 hours of Google Maps navigation, and 12.1 hours of WhatsApp video calling for the K14x. These are OPPO’s own measured claims, not independent results, and there is no directly comparable P4x battery test established here.
Cameras: similar main-camera resolution does not establish equal results
Both phones have a 50MP-class main rear camera in their published specifications, with a 2MP monochrome camera also listed for each. The P4x front-camera figure of 8MP comes from 91mobiles; OPPO specifies 5MP for the K14x. Megapixel counts do not show how well a camera handles focus, motion, low light, skin tones, or video, and no independent camera comparison between these models is established here.
What is the price difference?
On its comparison page accessed October 7, 2026, 91mobiles showed Amazon references of ₹21,939 for the realme P4x and ₹17,149 for the OPPO K14x. Subtracting those page values gives ₹4,790, with the P4x higher. This is a snapshot from one comparison page, not a guaranteed current, market-wide, or like-for-like price difference.

The comparison may not represent identical RAM/storage configurations. OPPO officially lists three K14x variants, while the comparison lists the P4x as 6GB/128GB; the full current P4x India variant matrix is not established here. Retail prices, stock, seller, card discounts, and exchange offers can all change the final amount. Compare the same memory and storage capacity where possible, and use the amount shown at checkout rather than treating the snapshot as a standing offer.

Choose the realme P4x if its strengths match your priorities
- You want the higher stated display resolution and refresh rate.
- You prefer the higher-tier chipset listed by the manufacturer.
- You value its advertised 7000mAh capacity.
Choose the OPPO K14x if its trade-offs and price suit you
- You prefer its slightly larger diagonal display and do not need the P4x’s higher resolution or refresh-rate claims.
- You find a lower checkout price for the same RAM/storage configuration.
- You want to choose among OPPO’s officially listed 4GB+64GB, 4GB+128GB, and 6GB+128GB options.
On the specifications established here, the P4x leads on display resolution, refresh rate, chipset tier, and advertised battery capacity. The K14x’s strongest case is its larger diagonal screen and a potentially lower price, but the observed price gap does not prove better value until the variants and live checkout totals match.
