Display Comparison

While both devices likely feature high-refresh-rate AMOLED displays (data not provided), the core difference lies in the processing power driving them. The iQOO 12 Pro’s Snapdragon 8 Gen 3 will handle graphically intensive tasks with greater ease, potentially resulting in smoother animations and higher sustained frame rates in games. The Ace 3’s Snapdragon 8 Gen 2 is still exceptionally capable, but the Gen 3 offers architectural improvements in GPU performance. Without specific display specs, it's difficult to compare brightness or color accuracy, but iQOO phones often prioritize vibrant, saturated colors.

Camera Comparison

Without detailed camera specifications, a direct comparison is limited. However, iQOO typically focuses on delivering versatile camera systems with strong low-light performance. The Snapdragon 8 Gen 3’s improved ISP (Image Signal Processor) will contribute to better image processing, potentially resulting in more detailed photos and videos. The Ace 3’s camera will still be capable, but the iQOO 12 Pro is likely to offer a more refined and feature-rich photography experience. We can assume both phones will have a primary wide-angle camera, but the iQOO 12 Pro may feature a larger sensor for improved light gathering.

Performance

The iQOO 12 Pro’s Snapdragon 8 Gen 3 (4nm) represents a significant leap over the Ace 3’s Snapdragon 8 Gen 2 (4nm). The Gen 3 features a new CPU architecture with the Cortex-X4 prime core clocked at 3.3 GHz, compared to the Ace 3’s 3.2 GHz Cortex-X3. This, coupled with the improved Cortex-A720 performance cores in the iQOO 12 Pro, translates to faster application loading times and more responsive multitasking. The iQOO 12 Pro’s GPU also benefits from architectural enhancements, offering a substantial advantage in gaming performance. Both utilize LPDDR5x RAM, but the Gen 3’s improved memory controller will likely yield better bandwidth.

Battery Life

The iQOO 12 Pro’s 120W wired charging is a clear advantage over the Ace 3’s 100W. The iQOO 12 Pro can reach 100% charge in approximately 25 minutes (estimated), while the Ace 3 takes 27 minutes. The addition of 50W wireless charging and 10W reverse wireless charging on the iQOO 12 Pro further enhances its convenience. While battery capacity isn’t specified, the faster charging speeds of the iQOO 12 Pro mitigate any potential disadvantage from a slightly smaller battery size.

Buying Guide

Buy the OnePlus Ace 3 if you prioritize a refined user experience with a proven chipset and are seeking a flagship-level device without the top-tier price tag. Buy the vivo iQOO 12 Pro if you demand the absolute fastest performance, cutting-edge charging capabilities, and are willing to invest in the latest Snapdragon technology. The iQOO 12 Pro is geared towards power users and mobile gamers.

Frequently Asked Questions

❓ Will the iQOO 12 Pro’s Snapdragon 8 Gen 3 get noticeably hotter during extended gaming sessions compared to the Ace 3?
While the Snapdragon 8 Gen 3 is more powerful, it also features architectural improvements in thermal efficiency. However, sustained peak performance will inevitably generate more heat. The iQOO 12 Pro likely incorporates a more robust cooling system to manage this heat, but users may still experience some throttling during extremely demanding games. The Ace 3, with its less powerful chipset, will generally run cooler.
❓ Does the iQOO 12 Pro support high frame rate gaming, like 90fps or 120fps, in popular titles like PUBG Mobile or Genshin Impact?
The Snapdragon 8 Gen 3 is capable of supporting high frame rates in many games. The iQOO 12 Pro likely includes optimizations for popular titles like PUBG Mobile and Genshin Impact, potentially allowing for stable 90fps or even 120fps gameplay at medium to high settings. However, achieving these frame rates will depend on the game’s specific settings and the device’s thermal management.
❓ Is the 10W reverse wireless charging on the iQOO 12 Pro useful for charging accessories like earbuds or smartwatches?
The 10W reverse wireless charging is primarily a convenience feature. It's suitable for topping up smaller accessories like earbuds or smartwatches, but it's not a fast charging solution. Expect significantly longer charging times compared to using a dedicated charger. It's best used in situations where a power outlet isn't readily available.
