The India-market spec sheets give the vivo T4x 5G an edge in listed display resolution and storage speed, while the OPPO K14x 5G supports storage-card expansion and lists a slightly higher maximum charging wattage. Both have a stated 6,500mAh typical battery and IP64 rating. A reliable current price difference cannot be established from the official listings reviewed: the vivo prices are for different memory configurations, and the OPPO sources do not state a price.
vivo T4x vs OPPO K14x: key specifications
The following figures are from the manufacturers’ India product pages. Configurations and availability can vary; vivo notes that specifications may vary by batch and usage, and OPPO also cautions that specifications may vary. See vivo’s T4x 5G specifications and OPPO’s K14x 5G specifications.

The brightness figures use manufacturer methods, so they are not a controlled head-to-head measurement. Chipset and storage specifications likewise describe components, not independently measured speed or gaming performance.

Which phone has the better display?
The vivo T4x has the sharper listed screen. Its 2408 × 1080 resolution and 393 ppi are substantially higher than the K14x’s 1570 × 720 and 256 ppi. Both list an LCD panel with a refresh rate of up to 120Hz. That shared maximum does not offset the resolution difference when fine text and image detail are priorities.

OPPO lists a higher HBM brightness figure—1125 nits typical versus vivo’s listed 1050 nits—but manufacturer measurement methods are not established as identical. Treat those figures as product specifications, not proof that one screen is brighter in every setting.
Performance and storage: what the spec sheets establish
vivo specifies a Dimensity 7300 5G with UFS 3.1 storage; OPPO specifies a Dimensity 6300 with UFS 2.2. These published component specifications favor the T4x on paper, but they do not establish a particular benchmark score, gaming frame rate, or real-world speed advantage.
Memory configurations differ as well. vivo lists up to 8GB RAM and a 256GB storage option. OPPO lists up to 6GB RAM and 128GB storage, but supports a storage card. The T4x’s listed storage is not expandable. Check the exact variant on sale before comparing prices or deciding whether its built-in capacity is enough.

Both manufacturers state a 6500mAh typical battery capacity. The T4x supports up to 44W FlashCharge, while the K14x lists up to 45W SUPERVOOC. The one-watt difference does not establish which phone charges faster: the charging systems, compatible adapters and charging conditions differ, and no direct charging test is available here.
Both phones carry an IP64 rating, which is limited ingress protection—not a promise that either is waterproof or safe to submerge. vivo says resistance can decline through wear and warns against liquid ingress. OPPO also qualifies its resistance claim and says liquid or dust damage is not covered under warranty. Follow each manufacturer’s handling and warranty terms.

Are the cameras different?
Both phones list a 50MP primary rear camera and a 2MP secondary camera, though the secondary camera types differ: vivo calls its unit a bokeh camera and OPPO lists a monochrome camera. The T4x lists an 8MP, f/2.05 front camera; the K14x lists a 5MP, f/2.2 front camera. Pixel counts and aperture figures alone do not determine image quality. No comparative photo samples or camera tests establish a winner.
What is the price difference between vivo T4x and OPPO K14x?
A like-for-like current price gap is not established by the official sources reviewed. The vivo Store listing showed ₹19,499 for the T4x 8GB + 128GB variant, while vivo’s official comparison page showed ₹16,999 for the 6GB + 128GB variant. Those prices apply to different configurations and page contexts; neither is a valid same-variant comparison with the other.

Quick Recap
Which phone should you choose?
- Choose the vivo T4x on specifications if a higher-resolution display, UFS 3.1 storage, or a listed 256GB configuration is more important to you.
- Consider the OPPO K14x if storage-card expansion is useful or you are considering its lower listed memory configurations. Confirm the exact card support and variant in the live product listing.
- For battery or charging, the published capacities are tied, and the maximum wattages do not establish real charging times.
- For camera quality, do not decide from megapixel counts alone; the available specifications do not establish a photo-quality winner.
- For value, compare current like-for-like prices. The available official price evidence is incomplete for a direct comparison.
