One noticeable difference between the user experience here is that the ROG 7 also supports hardware customization support through various settings. The pricing of the ROG 7 is not yet revealed, but as per trends, one can expect this phone to be listed at around $999, while the Zenfone 9 is available starting from $655.Designed for hardcore gamers, it makes sense why the ROG Phone 7 is priced at around a thousand dollars, considering the specs. A gamer who wants to outperform others and get into the competitive scenario should definitely consider spending his money on the ROG 7. PerformanceWe have a clear winner here. The ROG Phone 7 boasts Qualcomm's latest, the Snapdragon 8 Gen 2, which can smoothly run any operation you throw at it. The Zenfone 9, on the other hand, runs on Snapdragon 8+ Gen 1. Remember, this processor is more than enough for any everyday task, but heavy games run better on the 8 Gen 2 chipset.We have 16 gigs of the latest LPDDR5X RAM paired with 512GB UFS 4.0 storage on ROG 7, while Zenfone 9 has up to 256 GB UFS 3.1 storage with up to 16GB LPDDR5 RAM. So we can say that ROG 7 is better in performance.CameraBoth devices are similar in camera performance to say. They both contain the Sony IMX766X primary sensor with the same aperture. While the image processing in the 8 Gen 2 is better, as we have seen in the Samsung Galaxy S23 Ultra, the difference in image quality between Zenfone 9 and ROG Phone 7 is unnoticeable.Images come out crisp and detailed and have good HDR. The sensors shoot good color-accurate photos in daylight but might struggle in harsh lighting conditions like at night.If you are looking for a good phone for mobile photography, check out the best phones for photography.DisplayUndisturbed display of the ROG phone 7 ( Image via GSMArena)If other things don't matter and you want a phone with a beautiful display panel, the ROG 7 is a clear winner. The display is undisturbed without a camera notch and can refresh up to 165Hz. Zenfone 9 has a mini display when compared to ROG Phone 7, and this might be attractive to those who like compact phones.Displays on both devices use Samsung AMOLED technology and do their jobs pretty well. New users might not notice a huge difference between the 120Hz and 165Hz refresh rates, but for a gamer, a dynamic display is as important as the processor. So for long smooth gaming sessions, the points go to the ROG Phone 7.BatteryAs a gaming device, the ROG Phone 7 is expected to have a large battery, which it does with a 6000mAh battery that supports QuickCharge 5.0 and comes with a 65W PD charger in the box. It has two USB Type-C ports, one at the bottom and another at the side, allowing streamers to go live easily. The Zenfone 9 only has a 4300mAh battery that supports 30W fast charging and is more than enough for a day of usage.VerdictNow, the best part. The right choice among the best ASUS devices depends on your budget, what you want to do with the device on a daily basis, and the form factor. While the ROG Phone 7, with its advanced cooling system, is a great option for streamers and hardcore gamers, it might not be ideal for someone who wants a good phone for everyday usage.Surely the Zenfone 9 can run games pretty well, but the device might heat up, and prolonged sessions might result in lagging issues. There is a good price difference between the devices, and if you don't mind an 8.15-ounce smartphone making a bulge in your pocket, you should go for the ASUS ROG Phone 7.For more about ROG 7 and its comparisons, check out the following: ROG 7 vs. OnePlus 11 and ROG 7 vs. iPhone 14.
