Asus ROG Phone 8
- Superior gaming performance and cooling
- Compact flagship form factor
- Faster wired charging (International model)
- Potentially shorter battery life
- Less versatile camera system
Samsung Galaxy S24 Ultra
- Exceptional battery life
- Top-tier camera system with versatile zoom
- Brighter and larger display
- Slower wired charging
- Larger and heavier form factor
Display Comparison
The Samsung Galaxy S24 Ultra boasts a significantly brighter display, reaching a measured 1447 nits, ensuring excellent visibility even in direct sunlight. While the ROG Phone 8’s display specs aren’t provided, Asus typically prioritizes refresh rate and color accuracy for gaming. The S24 Ultra’s panel likely utilizes LTPO technology for adaptive refresh rates, conserving battery life. The S24 Ultra’s larger screen size also benefits content consumption and multitasking, while the ROG Phone 8’s smaller size enhances portability.
Camera Comparison
The S24 Ultra is expected to feature a more sophisticated camera system, leveraging larger sensors and advanced image processing algorithms. While specific details are missing, Samsung’s history suggests a focus on computational photography and versatile zoom capabilities. The ROG Phone 8, while capable, likely prioritizes image quality for social media sharing rather than professional-grade photography. The S24 Ultra’s OIS (Optical Image Stabilization) will likely be more advanced, resulting in sharper images and smoother video recording. Ignoring the typical 2MP macro lens found on many phones, the S24 Ultra’s main sensor size and aperture will be key differentiators.
Performance
Both devices are powered by the Qualcomm SM8650-AB/AC Snapdragon 8 Gen 3 (4nm), but subtle CPU clock speed differences exist. The S24 Ultra’s CPU reaches 3.39GHz, slightly exceeding the ROG Phone 8’s 3.3 GHz peak. This difference, coupled with potentially more aggressive thermal management in the S24 Ultra, could translate to sustained performance in demanding tasks. Both utilize LPDDR5x RAM, but the ROG Phone 8’s cooling system is specifically designed to minimize thermal throttling during extended gaming sessions, potentially offsetting the S24 Ultra’s clock speed advantage. The ROG Phone 8’s focus on gaming also suggests software optimizations geared towards maximizing frame rates and minimizing latency.
Battery Life
The Samsung Galaxy S24 Ultra demonstrates a clear advantage in battery life, achieving 13:49 hours of active use. The ROG Phone 8’s battery capacity isn’t specified, but its focus on high performance likely results in faster battery drain. The S24 Ultra’s 45W wired charging is slower than the ROG Phone 8’s 65W (International) or 30W (India) charging, but the S24 Ultra’s larger battery and efficient power management compensate for this. Both support 15W wireless charging, while the ROG Phone 8 offers 10W reverse wired charging compared to the S24 Ultra’s 4.5W reverse wireless, making the ROG Phone 8 a more effective power bank for accessories.
Buying Guide
Buy the Asus ROG Phone 8 if you prioritize mobile gaming above all else, demand a compact flagship form factor, and appreciate features like AirTriggers. Buy the Samsung Galaxy S24 Ultra if you need a top-tier camera system, exceptional battery life for all-day use, and a feature-rich experience encompassing productivity, entertainment, and photography.
