Samsung Galaxy Note20 Ultra

  • Integrated S Pen for productivity and creativity.
  • Premium build quality and design.
  • Versatile camera system (historically).

  • Slower charging speeds (25W).
  • Older chipset (Exynos 990 or Snapdragon 865+).
  • Potentially more throttling under sustained load.

Asus ROG Phone 5s

  • Significantly faster charging (65W).
  • More powerful Snapdragon 888+ chipset.
  • Optimized for gaming with superior thermal management.

  • Less emphasis on camera versatility.
  • Gaming-centric design may not appeal to all.
  • Lacks integrated stylus support.

Display Comparison

Both phones feature excellent displays, but cater to different needs. While the Note20 Ultra’s display specs aren’t provided, Samsung historically delivers vibrant, color-accurate panels. The ROG Phone 5s, though lacking specific brightness data, is optimized for gaming with a high refresh rate. The Note20 Ultra’s focus is on overall visual fidelity, while the ROG Phone 5s prioritizes responsiveness and smoothness during gameplay. The Note20 Ultra’s S Pen integration also adds a unique dimension to display interaction.

Camera Comparison

The Note20 Ultra, historically, has a strong camera reputation, but specific sensor details are missing. The ROG Phone 5s, being gaming-focused, likely prioritizes camera functionality less. The Note20 Ultra’s image processing is geared towards producing vibrant, social media-ready photos, while the ROG Phone 5s likely offers a more neutral profile. Without specific sensor size data for the Note20 Ultra, it’s difficult to definitively declare a winner, but Samsung’s history suggests a more versatile and refined camera experience.

Performance

The Asus ROG Phone 5s boasts a significant performance advantage with its Qualcomm Snapdragon 888+ 5G (5nm) chipset, compared to the Samsung Galaxy Note20 Ultra’s Exynos 990 (7nm+) or Snapdragon 865 5G+ (7nm+). The 888+’s Cortex-X1 prime core, clocked at 2.99 GHz, provides a substantial uplift in single-core performance. The ROG Phone 5s’ 5nm process node also translates to improved thermal efficiency, reducing throttling during extended gaming sessions. The Note20 Ultra’s CPU, while capable, is architecturally older and less efficient. The ROG Phone 5s’ superior GPU will deliver higher frame rates and more detailed graphics in demanding games.

Battery Life

The ROG Phone 5s’ 65W wired charging is a game-changer, achieving 70% charge in 30 minutes and 100% in 52 minutes, vastly outperforming the Note20 Ultra’s 25W charging. While battery capacity isn’t specified for either device, the ROG Phone 5s’ faster charging mitigates any potential capacity disadvantage. The Note20 Ultra offers 15W wireless charging and 4.5W reverse wireless, while the ROG Phone 5s provides 10W reverse *wired* charging, a less common but potentially faster method for topping up accessories.

Buying Guide

Buy the Samsung Galaxy Note20 Ultra if you need a premium smartphone with a built-in stylus for note-taking, document editing, and creative tasks, alongside a capable camera system and a more refined software experience. Buy the Asus ROG Phone 5s if you prioritize mobile gaming above all else, demanding the highest frame rates, sustained performance under load, and the fastest possible charging speeds, even if it means sacrificing some mainstream features.

Frequently Asked Questions

❓ Does the Exynos 990 in the Note20 Ultra overheat during prolonged gaming sessions?
The Exynos 990 is known to generate more heat than the Snapdragon 865+ or 888+. While Samsung implemented cooling solutions, extended gaming at high settings can lead to noticeable throttling, reducing sustained performance. The ROG Phone 5s, with its Snapdragon 888+ and advanced cooling system, is significantly better equipped to handle thermal demands.
❓ Is the 10W reverse wired charging on the ROG Phone 5s useful for charging accessories like earbuds?
Yes, the 10W reverse wired charging is a convenient feature for topping up accessories like wireless earbuds or smartwatches. While not as fast as dedicated chargers, it's a practical solution when you're away from a power outlet and need a quick boost for a smaller device. The Note20 Ultra's 4.5W reverse wireless is slower and less efficient.
❓ Can the Asus ROG Phone 5s maintain 60fps in demanding games like Genshin Impact?
The ROG Phone 5s can comfortably maintain 60fps in Genshin Impact at high settings. Its Snapdragon 888+ chipset and optimized cooling system provide the necessary horsepower to handle the game's demanding graphics. It can even push higher frame rates with settings adjustments, offering a smoother gaming experience than the Note20 Ultra.
