OnePlus Ace 5 Ultra
- Potentially higher peak CPU performance with Dimensity 9400+
- Bypass charging minimizes heat during gaming
- 100W wired charging is still very fast
- Dimensity 9400+ may throttle more under sustained load
- Lacks wireless charging
vivo iQOO 12 Pro
- More efficient Snapdragon 8 Gen 3 chipset
- 120W wired and 50W wireless charging
- Likely superior camera system
- Slightly lower peak CPU clock speed
- May be more expensive
Display Comparison
While display specs are absent from the provided data, both phones likely feature high refresh rate AMOLED panels. However, the iQOO 12 Pro, given vivo’s history, is expected to have a slightly more color-accurate display with potentially higher peak brightness. The iQOO 12 Pro’s inclusion of 50W wireless charging suggests a more advanced display controller capable of handling higher power demands, potentially translating to better display quality.
Camera Comparison
Without camera specifications, a direct comparison is limited. However, vivo’s iQOO sub-brand typically prioritizes camera performance, suggesting the iQOO 12 Pro likely features a more sophisticated camera system with larger sensors and advanced image processing algorithms. The Snapdragon 8 Gen 3’s ISP (Image Signal Processor) is also generally considered superior, offering better dynamic range and low-light performance. The Ace 5 Ultra will likely offer a competent camera, but the iQOO 12 Pro is expected to excel in this area.
Performance
The core battle lies in the chipsets. The OnePlus Ace 5 Ultra’s Dimensity 9400+ (3nm) boasts a Cortex-X925 prime core clocked at 3.73 GHz, potentially offering a slight edge in single-core performance compared to the iQOO 12 Pro’s Snapdragon 8 Gen 3 (4nm) with its 3.3 GHz Cortex-X4. However, the Snapdragon 8 Gen 3’s 4nm process offers superior thermal efficiency, mitigating throttling during sustained workloads. The Dimensity 9400+'s CPU configuration (1+3+4) versus the Snapdragon's (1+3+2+2) suggests a focus on maximizing peak performance at the expense of sustained efficiency. The iQOO 12 Pro’s LPDDR5x RAM, standard for flagships, will complement the Snapdragon’s efficiency.
Battery Life
The iQOO 12 Pro’s 120W wired charging significantly surpasses the Ace 5 Ultra’s 100W, translating to a faster 0-100% charge time. The addition of 50W wireless charging on the iQOO 12 Pro is a substantial advantage, offering convenience without sacrificing charging speed. While the Ace 5 Ultra offers bypass charging, minimizing heat during gaming, the iQOO 12 Pro’s superior thermal management from the 4nm Snapdragon 8 Gen 3 may negate the need for this feature.
Buying Guide
Buy the OnePlus Ace 5 Ultra if you prioritize a potentially higher peak CPU performance, especially in heavily optimized games, and value the 100W wired charging with bypass charging for minimal heat during gaming. Buy the vivo iQOO 12 Pro if you prefer a more refined and thermally managed experience, benefit from faster overall charging speeds (including wireless), and appreciate Qualcomm’s established ecosystem and software optimization.
