Related post: Roku Streaming Stick+ Review Onto the Fire Stick 4K versus the 4K Max, the most noticeable improvements at least in the hardware department is the inclusion of WiFi 6 (802.11a/b/g/n/ac/ax) support and 2GB of RAM. Comparatively, the Fire Stick 4K supports WiFi 5 dual-band on 802.11a/b/g/n/ac wifi networks and 1.5GB of RAM. WiFi 6 is the latest wireless WiFi standard and it offers faster data speed, better congestion, security and power management. However, the 4K Max needs a WiFi 6 router to take advantage of these benefits. But if you have the common WiFi 5 AC router, the stick will still work except you won’t take advantage of WiFi 6 capabilities. With those differences, the Fire Stick 4K and 4K Max have a lot in common. Both support 4K UHD, HDR, and HDR10+ streaming, as well as Dolby Vision and Dolby Atmos which provide great sound and picture quality. The 4K Max however, supports the new AV1 codec upto 3840x2160p(4K) at 60 FPS. Both come with 8GB of storage, have Bluetooth 5.0 LE, and come with Alexa Voice remote.
