Samsung Galaxy Note20 Ultra 5G

  • Integrated S Pen for productivity and creativity
  • Versatile and high-quality camera system
  • Excellent display brightness and color accuracy

  • Slower charging speed (25W)
  • Potentially less powerful processor (Exynos variant)
  • Less focused on gaming features

Asus ROG Phone 5 Ultimate

  • Significantly faster Snapdragon 888 processor
  • Ultra-fast 65W charging
  • Gaming-centric features (high refresh rate, cooling)

  • Camera system is secondary to gaming
  • Less refined overall user experience
  • Bulkier design

Display Comparison

The Note20 Ultra boasts a measured peak brightness of 1024 nits, providing excellent visibility outdoors. While the ROG Phone 5 Ultimate’s peak brightness isn’t specified, its focus is on a high refresh rate for smoother gaming. Both feature infinite (nominal) contrast ratios, typical of AMOLED panels. The Note20 Ultra’s display is geared towards color accuracy and general use, while the ROG Phone’s prioritizes responsiveness for gaming. The ROG Phone’s higher refresh rate (likely 144Hz, based on the series) will provide a competitive edge in fast-paced games, a feature absent on the Note20 Ultra.

Camera Comparison

Both phones offer capable camera systems, but with different priorities. The Note20 Ultra’s camera is designed for versatile photography and videography, excelling in detail and dynamic range. The ROG Phone 5 Ultimate’s camera, while competent, is secondary to its gaming focus. Without specific sensor details for the ROG Phone, it’s safe to assume the Note20 Ultra likely has a larger main sensor and more sophisticated image processing. The Note20 Ultra’s video capabilities are likely superior, given Samsung’s expertise in this area. The inclusion of a 2MP macro camera on either device is largely inconsequential, offering minimal benefit over standard digital zoom.

Performance

This is where the ROG Phone 5 Ultimate truly shines. Its Qualcomm Snapdragon 888 5G (5nm) chipset represents a significant leap over the Note20 Ultra’s Exynos 990 (7nm+) or Snapdragon 865 5G+ (7nm+). The Snapdragon 888’s Cortex-X1 prime core and more efficient 5nm process translate to noticeably faster CPU and GPU performance. The Note20 Ultra’s CPU configuration varies by region – the global version with the Exynos 990 may exhibit more thermal throttling under sustained load compared to the US version with the Snapdragon 865 5G+. The ROG Phone 5 Ultimate’s advanced cooling system further mitigates throttling, ensuring consistent performance during long gaming sessions.

Battery Life

The Note20 Ultra has an endurance rating of 88 hours, indicating solid battery life. However, the ROG Phone 5 Ultimate compensates for potentially lower mAh capacity with its incredibly fast 65W charging. Achieving 70% charge in 30 minutes and 100% in 52 minutes is a game-changer for gamers who need to quickly top up between matches. The Note20 Ultra’s 25W charging feels comparatively slow. The ROG Phone 5 Ultimate also offers 10W reverse wired charging, while the Note20 Ultra provides 4.5W reverse wireless charging – a minor convenience feature on both devices.

Buying Guide

Buy the Samsung Galaxy Note20 Ultra 5G if you require a versatile device with exceptional note-taking capabilities, a refined camera experience, and a more traditional smartphone aesthetic. Buy the Asus ROG Phone 5 Ultimate if you prioritize uncompromising gaming performance, rapid charging, and a feature set tailored to mobile esports and extended gaming sessions.

Frequently Asked Questions

❓ Does the Exynos 990 in the global Note20 Ultra overheat during extended gaming sessions?
The Exynos 990 is known to be less thermally efficient than the Snapdragon 865 5G+. While the Note20 Ultra has cooling, prolonged gaming at high settings can lead to noticeable throttling, reducing performance. The ROG Phone 5 Ultimate’s Snapdragon 888 and advanced cooling system are far better equipped to handle sustained gaming loads.
❓ Is the 10W reverse wired charging on the ROG Phone 5 Ultimate useful for charging accessories like earbuds?
While 10W reverse wired charging is present, it's relatively slow. It's suitable for emergency top-ups of small accessories like earbuds or a smartwatch, but not for quickly charging larger devices like another phone. The Note20 Ultra's reverse wireless charging is even slower.
❓ Can the ROG Phone 5 Ultimate run games at 90fps or higher?
Yes, the ROG Phone 5 Ultimate, with its high refresh rate display (likely 144Hz) and powerful Snapdragon 888, can run many popular games at 90fps or even higher, depending on the game's settings and optimization. This provides a significantly smoother and more responsive gaming experience than the Note20 Ultra’s 60Hz display.
❓ How does the S Pen integration affect the Note20 Ultra's usability for students or professionals?
The S Pen is a key differentiator for the Note20 Ultra. It enables precise note-taking, document annotation, and creative tasks. For students and professionals who frequently handwrite notes or require precise input, the S Pen is a valuable tool that the ROG Phone 5 Ultimate simply cannot match.
