vivo iQOO Z10 Turbo+

  • Newer Dimensity 9400+ chipset for superior CPU performance
  • More power-efficient 3nm process
  • Reverse wired charging for topping up accessories

  • Slower 90W charging compared to the K70 Ultra
  • Potential for less refined software experience (typical of iQOO)

Xiaomi Redmi K70 Ultra

  • Ultra-fast 120W charging for minimal downtime
  • Potentially more polished software experience (Xiaomi's MIUI)
  • PD3.0 support for wider charger compatibility

  • Older Dimensity 9300+ chipset with a 4nm process
  • Less powerful CPU core (Cortex-X4 vs X925)

Display Comparison

While both devices likely feature high-refresh-rate AMOLED displays (specs not provided), the core battle lies within. The iQOO Z10 Turbo+ benefits from the newer Dimensity 9400+ which, while not directly impacting the display, suggests a more modern overall design and potentially better display calibration. The Redmi K70 Ultra’s display quality will depend on panel sourcing and tuning, but the faster 120W charging could indirectly allow for more screen-on time.

Camera Comparison

Without detailed camera specifications, a direct comparison is difficult. However, both brands typically prioritize strong main sensors. The iQOO Z10 Turbo+’s performance will depend on the sensor size and image processing algorithms employed. Xiaomi’s Redmi K70 Ultra, benefiting from Xiaomi’s extensive camera software expertise, may offer more refined image processing and potentially better low-light performance. The absence of information regarding OIS is a key omission; its presence on either device would be a significant advantage.

Performance

The heart of the matter: the Mediatek Dimensity 9400+ in the iQOO Z10 Turbo+ versus the Dimensity 9300+ in the Redmi K70 Ultra. The 9400+ utilizes a 3nm process, offering improved power efficiency and thermal headroom compared to the 9300+'s 4nm node. Crucially, the 9400+ features the Cortex-X925 prime core clocked at 3.73 GHz, a step up from the 9300+'s Cortex-X4 at 3.25 GHz. This translates to a noticeable advantage in single-core performance, benefiting responsiveness and lighter tasks. The 9400+ also has more X4 cores (3 vs 3) which will help in multi-core workloads. Both phones utilize LPDDR5x RAM, but the 9400+'s superior CPU architecture will likely result in smoother multitasking and gaming experiences.

Battery Life

The Redmi K70 Ultra’s 120W wired charging is a clear advantage, promising a full charge in just 24 minutes. The iQOO Z10 Turbo+’s 90W charging is still fast, but noticeably slower. While battery capacity isn’t specified, the Dimensity 9400+’s 3nm process should contribute to better power efficiency, potentially mitigating the difference in charging speed. The K70 Ultra also supports PD3.0, offering wider compatibility with chargers, while the iQOO Z10 Turbo+ adds reverse wired charging, a niche but useful feature.

Buying Guide

Buy the vivo iQOO Z10 Turbo+ if you absolutely need the fastest possible CPU performance for demanding tasks like video editing or emulation, and value the latest processor architecture. Buy the Xiaomi Redmi K70 Ultra if you prioritize incredibly fast charging, a potentially more polished software experience, and are less concerned with having the absolute newest CPU core.

Frequently Asked Questions
