The entry of the Chromecast has provided TV experience with smart functionalities that allows the streaming of videos, pictures and audio over WiFi. Its first generation unit has been launched by Google in 2013.

The success of the product has been further reinforced when the Chromecast 2 surfaced a couple of years later. This second generation product introduces a re-designed frame including a more powerful processor.

This October, Google brings forth an enhanced device which showcases the far-reaching video experience. With the release of the Chromecast Ultra, the 4K streaming resolution has been established.

With the latest Chromecast in the market, enthusiasts and users wonder if the new version is far better than the second generation series. From the looks of it, the Ultra is perhaps a step higher.

Although the new model still assumes the small and circular form of the previous series, quite noticeable is the change made on the Chrome logo. The replacement has been simplified with a 'G' mark.

The Chromecast 2 runs a full HD 1080 x 1920p resolution. It has a 512MB RAM. Storage space is set at 256MB with a micro USB option.

While the specifications of the Chromecast Ultra is yet to be revealed, previous developments can be used as basis for its features. Considering that Marvell's Armada chips run the predecessors of the new unit, it is perceived that the Google's incoming product will also have the same processor. However, the upgraded chips are expected to be either the high version Armada 1500 Pro4K or the Armada 1500 Ultra which presents a highly-touted 1.8x performance enhancement.

Aside from accommodating HDMI and WiFi connections, the Ultra is the first external streaming device to support both HDR formats, namely, the HDR10 and the Dolby Vision. Resolution is pegged at 3840 x 2160p. It has included an Ethernet adapter which allows direct connection to a router or modem.

It is important to note that upgrading to the Ultra is only appropriate if a 4K TV is in place.
