We already listed pros and cons of each model. However, you may also find useful to look at their common strengths and weaknesses shown side-by-side.

Screen

Sony Alpha 6400 and Sony Cyber-shot DSC-RX100 III have 3.0" Tilting screens with 922k dot and 1,229k dot resolutions respectively. Tilting screen makes cameras very useful for photography purposes but not so useful for video shooting. Sony Alpha 6400 also features touchscreen which has advantages such as easy menu navigation, intuitive controls, quick setting adjustment and most importantly a Touch-to-Focus functionality allowing users to select a specific point on the screen where they want the camera to focus. This feature can be helpful for achieving precise focus in both photo and video recording.

Viewfinder

Sony Alpha 6400 has a built-in 0.39" Electronic viewfinder with 2,359k dot resolution and Sony Cyber-shot DSC-RX100 III has a built-in Electronic viewfinder with 1,440k dot resolution. They both have 100% coverage.

Sony Alpha 6400 features a 24.2 megapixel APS-C CMOS sensor with dimensions of 23.5 x 15.6 mm and a total area of 366.6 mm². Its native ISO range is 100 - 32,000 and expands to 100 - 102,400 in boosted mode. Sony Cyber-shot DSC-RX100 III features a 20.1 megapixel 1-inch BSI-CMOS sensor with dimensions of 13.2 x 8.8 mm and a total area of 77.4 mm². Its native ISO range is 125 - 12,800 and expands to 80 - 25,600 in boosted mode.

Sony Cyber-shot DSC-RX100 III has BSI-CMOS sensor, short for Backside Illuminated Complementary Metal-Oxide-Semiconductor sensor. In traditional CMOS sensors, the wiring and circuitry are located on the front side of the sensor, which can block some of the incoming light. BSI technology flips this design by placing the photosensitive elements (pixels) on the backside of the sensor, allowing more light to reach the pixels. This significantly enhances light sensitivity and improves low-light performance. BSI-CMOS sensors are particularly effective in low-light conditions, as they can capture more light, resulting in brighter and less noisy images. This makes them well-suited for indoor and night photography. BSI-CMOS sensors deliver a higher SNR and reduced cross-talk.

Sony Alpha 6400 is equipped with BIONZ X processor and can take pictures up to 6000 x 4000 resolution. Sony Cyber-shot DSC-RX100 III is equipped with Bionz X processor and can take pictures up to 5472 x 3648 resolution. It can also take pictures with lower resolution like 3:2 mode: 3888x2592, 2736x1824; 4:3 mode: 4864x3648, 3648x2736, 2592x1944, 640x480; 16:9 mode: 5472x3080, 2720x1528; 1:1 mode: 3648x3648, 2544x2544, 1920x1920 with 1:1, 4:3, 3:2, 16:9 aspect ratios.
