Among all the ARM processors listed as above for commercial tablet advertising, we would like to putRK3288 on the top of the performance ladder, due to the obvious key factors including 4K videodecoder, 5G WiFi (802.11 ac) & Gigabyte Lan for multi‐cast IP streaming. The other reason whyRK3288 gains the top position is that tablet advertising professionals learned from the mistakes,failures, and drawbacks of what they got from the long learning curve of RK3188, the No.2 runner ofthe commercial tablet performance racing.

And RK3288 is introduced together with Android 5.1, this version of Android carried someexpectations that are not available in the widely accepted & popular Android 4.4: screen pinning(multi‐screen), and there are quite more apps available based on such a newer version.

The benchmark of commercial tablet is Allwinner A20 powered tablet display and Rockchip RK3188based retail tablet. When Allwinner is more developer‐friendly, A20 is widely used for tailor‐madecommercial, retail & industrial applications when peripherals & device communication are needed.

Allwinner A20 Mother Board Design NormRockchip RK3188 as a follower, starts retail & commercial application from a designed‐for‐priceconsumer‐line mother board. Thanks to Rockchip’s partnership with Intel which sends a clear signalto industry that Rockchip gained entrenched advantage in reputation which influences the end‐usersand the buyer‐preference based marketing finally helps Rockchip won over the market share ofcommercial tablet market that was previously occupied by Allwinner family.

Allwinner A83T, the Octa‐core processor, entered the market with a super short boot up time(as shortas 10s), for comparison, RK3188 is almost in the same level as A83T in performance.

With A83T targeting the middle & high‐end market, Allwinner released A33, the down‐performancemodel of Allwinner A20, it was designed for small sized screens like 10.1” or below sized retail tablet,business hospitality tablet used for roommanagement (touchscreen controller for example).

Amlogic family, owned by Chinese and headquartered in US, it entered the commercial tablet marketearliest since 2012 when dual‐core processor was new to mass market. Amlogic is operated in awesternized way to buy up‐to‐date advanced IP for its ARM processor, it is NOT developer friendly, butit is built with managed engineering & due consideration for long‐term‐win strategy. We choose it foropenframe touch panel at the early stage when hardware options are very few. We built abundantcommunication interface for various commercial applications, see the following circuit diagram.

In early 2014, after CES, 4K became a tech‐topic in the industry, RK3288 took the lead again, but dueto its market‐first strategy, it is mass production ready until later 2015 for commercial use. During thistime, Amlogic learned the market and released 64‐bit quad‐core S905, it gained the top position in 4Kset‐top‐box market thanks to its great success in tele‐operator market. Amlogic’s main know‐how forcommercial application is the color reproduction and hardware video decoding. Our MP40 is one ofthe very few commercial use 4K media player that can run for months without failure. But due to thefact that Amlogic S905 does't have built‐in LCD panel interface, it lost the power for high‐end commercialtablet, while RK3288 takes the lead again and occupied the market.

In a long‐term, the solution design norm for mass market belongs to Rockchip, from RK3188 to RK3288.
