Samsung Galaxy S23+

  • Brighter display for outdoor visibility
  • More compact and pocketable design
  • Refined software experience and wider ecosystem

  • Slower charging speed
  • Less focused on gaming-specific features
  • Potentially lower sustained performance under extreme load

Asus ROG Phone 7 Ultimate

  • Faster 65W charging for quick top-ups
  • Superior cooling system for sustained gaming
  • Gaming-centric features like AirTriggers and customizable settings

  • Larger and heavier design
  • Lower peak display brightness
  • Camera likely not as refined as the S23+

Display Comparison

Both devices utilize the Snapdragon 8 Gen 2, but their displays differ. The S23+ boasts a measured peak brightness of 1205 nits, exceeding the ROG Phone 7 Ultimate’s 1095 nits, making it more visible outdoors. While the ROG Phone 7 Ultimate claims an infinite contrast ratio, the S23+’s display technology likely offers comparable performance. The S23+’s smaller size (data not provided) contributes to a higher pixel density, potentially resulting in a sharper image. Neither device specifies PWM dimming rates, a crucial factor for users sensitive to flicker.

Camera Comparison

Both devices offer photo and video capabilities, but detailed camera specs are absent. Given Samsung’s history, the S23+ likely prioritizes image processing for vibrant, shareable photos, while Asus may lean towards a more natural look. Without sensor size or aperture information, a direct comparison is difficult. However, the ROG Phone 7 Ultimate’s gaming focus suggests camera quality is secondary to other features. The inclusion of a 2MP macro camera on either device is likely a marketing tactic with limited practical benefit.

Performance

Both phones are powered by the Qualcomm Snapdragon 8 Gen 2 (4nm), but with slight CPU clock speed variations. The S23+ features a 3.36 GHz Cortex-X3, while the ROG Phone 7 Ultimate clocks in at 3.2 GHz. This difference, while measurable, is unlikely to be noticeable in most real-world scenarios. Both utilize the same core configuration for A715, A710, and A510 cores. The ROG Phone 7 Ultimate’s cooling system, a hallmark of the ROG series, is expected to provide superior sustained performance under heavy load, mitigating thermal throttling during extended gaming sessions. Both utilize LPDDR5x RAM (spec not provided, but standard for this tier).

Battery Life

The Asus ROG Phone 7 Ultimate boasts an endurance rating of 131 hours, slightly exceeding the Samsung Galaxy S23+'s 111-hour rating. However, the S23+ delivers a solid 13:51h of active use. The ROG Phone 7 Ultimate’s 65W wired charging, completing a full charge in 42 minutes, is significantly faster than the S23+'s 45W charging (65% in 30 minutes). The ROG Phone 7 Ultimate also offers 10W reverse wired charging, a unique feature absent on the S23+, which provides 4.5W reverse wireless charging. The ROG Phone 7 Ultimate’s faster charging is a significant advantage for gamers who need to quickly top up their battery between matches.

Buying Guide

Buy the Samsung Galaxy S23+ if you need a premium smartphone with a versatile camera system, a more manageable size for one-handed use, and a polished software experience. Buy the Asus ROG Phone 7 Ultimate if you prioritize maximum gaming performance, extended play sessions thanks to its advanced cooling, and don't mind a larger, more specialized device.

Frequently Asked Questions

❓ Does the Snapdragon 8 Gen 2 in the ROG Phone 7 Ultimate overheat during prolonged gaming sessions?
While the Snapdragon 8 Gen 2 is a powerful chip, the ROG Phone 7 Ultimate’s advanced cooling system – including vapor chamber and potentially external fan accessories – is specifically designed to mitigate thermal throttling. This allows for sustained peak performance during extended gaming sessions, unlike some other devices with the same chipset.
❓ Is the 10W reverse wired charging on the ROG Phone 7 Ultimate useful for charging accessories like earbuds?
Yes, the 10W reverse wired charging is a convenient feature for topping up smaller accessories like wireless earbuds or a smartwatch. While not as fast as dedicated chargers, it provides a useful emergency charging option when a power outlet isn't available.
❓ How does the camera processing differ between the S23+ and the ROG Phone 7 Ultimate?
Samsung typically employs a more vibrant and saturated image processing style, aiming for immediately shareable photos. Asus, given its gaming focus, may prioritize a more natural and accurate color representation. Without detailed camera samples, it's difficult to say definitively, but expect a noticeable difference in the 'look' of the photos.
❓ Does the ROG Phone 7 Ultimate support high refresh rate gaming (90fps or 120fps) in popular titles like PUBG Mobile?
The ROG Phone 7 Ultimate is designed to support high refresh rate gaming in many popular titles, including PUBG Mobile. The device’s high refresh rate display and powerful chipset, combined with Asus’s gaming optimizations, allow for smoother and more responsive gameplay. Specific frame rate support will depend on the game’s settings and optimization.
