Display Comparison

The vivo X100 Ultra boasts a significantly brighter display, reaching a measured 1801 nits, making it exceptionally visible outdoors. While the OnePlus Ace 3’s display specs aren’t provided, the X100 Ultra’s brightness advantage is substantial. The X100 Ultra’s panel likely utilizes LTPO technology for adaptive refresh rates, contributing to power efficiency, a feature not confirmed for the Ace 3. This difference in peak brightness directly benefits users who frequently consume content in bright sunlight.

Camera Comparison

Without detailed camera specifications for either device, a direct comparison is limited. However, vivo’s X-series is renowned for its camera prowess, and the ‘Ultra’ designation suggests a premium imaging system. The Snapdragon 8 Gen 3’s improved ISP (Image Signal Processor) will contribute to better image processing in the X100 Ultra. While the Ace 3 likely offers a capable camera, the X100 Ultra is expected to deliver superior image quality, especially in low-light conditions, and potentially offer more advanced features.

Performance

The core difference lies in the chipsets: the OnePlus Ace 3 utilizes the Snapdragon 8 Gen 2 (4nm), while the vivo X100 Ultra features the newer Snapdragon 8 Gen 3 (4nm). The Gen 3’s CPU architecture – Cortex-X4 prime core clocked at 3.3 GHz versus the Ace 3’s 3.2 GHz Cortex-X3 – offers a noticeable performance uplift, particularly in demanding tasks. The X100 Ultra’s CPU also benefits from a more efficient Cortex-A720 configuration. Both phones utilize 4nm fabrication, but the architectural improvements in the Gen 3 translate to better sustained performance and thermal management, benefiting gamers and power users.

Battery Life

The vivo X100 Ultra demonstrates impressive battery endurance, achieving 12:55h of active use. The OnePlus Ace 3’s battery capacity is unknown, but its 100W wired charging is significantly faster than the X100 Ultra’s 80W wired charging, achieving a full charge in just 27 minutes. The X100 Ultra compensates with 30W wireless and reverse wireless charging, offering greater versatility. Users prioritizing minimal downtime will favor the Ace 3’s faster wired charging, while those valuing convenience and wireless options will appreciate the X100 Ultra’s broader charging ecosystem.

Buying Guide

Buy the OnePlus Ace 3 if you need a powerful gaming phone that won't break the bank, and value incredibly fast wired charging. It's ideal for users who prioritize performance-per-dollar. Buy the vivo X100 Ultra if you prefer a no-compromise flagship experience with the latest processor, a stunningly bright display, and the convenience of wireless charging and reverse wireless capabilities. It caters to users who demand the best and are willing to pay for it.

Frequently Asked Questions

❓ Does the Snapdragon 8 Gen 3 in the vivo X100 Ultra get noticeably hotter than the Snapdragon 8 Gen 2 in the OnePlus Ace 3 during extended gaming sessions?
While both chips are fabricated on a 4nm process, the Snapdragon 8 Gen 3 features architectural improvements and a more efficient CPU configuration. This generally translates to better thermal management, meaning the X100 Ultra is likely to maintain higher sustained performance for longer periods without significant throttling compared to the Ace 3, though both phones will experience some heat during intense gaming.
❓ How much does the 30W wireless charging on the vivo X100 Ultra impact the overall charging time compared to the OnePlus Ace 3’s 100W wired charging?
Wireless charging is inherently slower than wired charging. While 30W wireless charging is respectable, the OnePlus Ace 3’s 100W wired charging will fully charge the device in approximately 27 minutes. The X100 Ultra will take considerably longer to reach 100% via wireless charging, making the Ace 3 the clear winner for users prioritizing speed.
❓ Is the difference in display brightness between the two phones noticeable in everyday use, or only in direct sunlight?
The 1801 nit peak brightness of the vivo X100 Ultra is most dramatically noticeable in direct sunlight, where the screen remains easily readable. However, even in indoor environments, the higher brightness contributes to a more vibrant and immersive viewing experience, particularly when consuming HDR content.
