Group 1: Vibration Motor Performance - Xiaomi 15 Ultra uses ESA 0809B motor, which is decent but lacks top-tier performance in vibration feedback, leading to a subpar typing experience [7]. - OPPO Find X8 Ultra features the CSA 0916 Turbo motor, recognized as a top-tier option, providing excellent vibration feedback and responsiveness, making it stand out in user experience [9]. - Vivo X200 Ultra opts for a different motor, the Dongguan East Magnetic 9593, which offers acceptable response speed but falls short in vibration strength compared to OPPO [11]. Group 2: Speaker Quality - Xiaomi 15 Ultra combines the AAC 1014E and Goer 1115D speakers, enhanced with N'BASS acoustic materials, resulting in solid hardware specifications [13]. - OPPO Find X8 Ultra utilizes AAC 1012 and AAC 1115E, aiming for balanced sound quality [13]. - Vivo X200 Ultra boasts the largest speaker configuration with AAC 1210D and Goer 1511P, but the sound lacks fullness and depth due to insufficient tuning [16]. Group 3: Microphone Configuration - Both Xiaomi and OPPO include four microphones for superior multi-channel recording capabilities [18]. - Vivo X200 Ultra has reduced its microphone count from four to three, which contradicts its focus on video recording capabilities [18]. Group 4: Display Performance - All three models support 2K resolution and 120Hz refresh rate, but differ in brightness: Xiaomi 15 Ultra at 700 nits, OPPO Find X8 Ultra at 780 nits, and Vivo X200 Ultra at 825 nits [19]. - Vivo X200 Ultra excels in peak brightness at 1818 nits, significantly outperforming the others [21]. - Vivo X200 Ultra employs advanced high-frequency PWM dimming across all brightness levels, enhancing eye comfort [22]. Group 5: Touch Sampling Rate - Xiaomi 15 Ultra and Vivo X200 Ultra achieve around 300Hz touch sampling rate, ensuring smooth user experience [24]. - OPPO Find X8 Ultra claims 240Hz but measures only 125Hz in practice, indicating a performance shortfall [24]. Group 6: Communication Capabilities - Vivo X200 Ultra supports the most 5G bands at 25, followed by Xiaomi 15 Ultra with 23, and OPPO Find X8 Ultra with 18 [25]. - Xiaomi 15 Ultra offers comprehensive satellite communication support, enhancing user safety during outdoor activities [25]. - Xiaomi 15 Ultra features the highest USB interface specifications, facilitating faster data transfer for professional users [27]. Group 7: Overall Summary - Xiaomi 15 Ultra excels in communication and interface specifications but has average motor and display performance [28]. - OPPO Find X8 Ultra is distinguished by its superior vibration motor and user experience but has limitations in communication capabilities [28]. - Vivo X200 Ultra leads in display technology but suffers from audio tuning issues and reduced microphone count [30].
