Talk:Rockchip

Where does it indicate that RK2818 has a max clock of 640MHz? Everything on the market is 622MHz (rounding down).

ARM

It's not clearly stated for every chip which ARM architecture generation it is. For example, what architecture is the Rockchip 2818? I've heard it might be ARM9 or ARM11... --Arny (talk) 11:37, 19 April 2011 (UTC)

"ARM9" is NOT an "instruction set"

In the table at the bottom, "ARM9" appears under the "CPU Instruction Set" column. This is incorrect. ARM ISAs have the prefix "ARMv" not "ARM", e.g. ARM11 systems use the ARMv6 instruction set. I don't have time to clean up the mistakes in the article but I do have time to make a record of them here.

Reorder the table and features list?

Possibly the table should come first with the detailed feature descriptions afterwards. — Preceding unsigned comment added by Bostwickenator (talk • contribs) 22:00, 25 April 2013 (UTC)

Inconsistency in RK31xx series information

Article says "The RK3188 ... features a quad core CPU with 2 GHz frequency or faster". Further down the "List of Rockchip SoC" table entry for RK3188 says "Up to 1.8 GHz". 96.26.79.253 (talk) 12:30, 30 April 2013 (UTC)

• The details page on their website actually says 1.6 but a lot of devices are shipping with 1.8 listed. Bostwickenator (talk) 23:56, 4 May 2013 (UTC)
  • Then should it read "features a quad core CPU with 2 GHz frequency or slower"? 96.26.79.253 (talk) 01:32, 10 June 2013 (UTC)

Specifications of RK3288

The exact specifications of the RK3288 are still uncertain as of this writing, with Rockchip having made conflicting statements. So the specifications are left with multiple possibilities (Cortex A12/17, Mali-T764/T624) in the article. If you dig deeper into news articles at websites like CNXSoft [1] (especially article comments sections) there continues to be uncertainty about the real availability of the RK3288 ("limited trial production run in June" of RK3288-based device etc). Over-optimistic statements about availability or specifications are very common in the Chinese supply chain, and products sometimes show up in online shops months before they are available or shipped (if at all).

High power draw was also noted. In the semiconductor press, there have been reports about problems with the 28nm process at GlobalFoundries that Rockchip has been using for recent products. It is possible that Rockchip has made redesigns of the chip with different Cortex or GPU cores. The specs should be updated only after end products are clearly available in mass production.

Weird we can't get solid info from rockchip.   http://www.cnx-software.com/2014/01/10/rockchip-rk3288-vs-rk3188-performance-comparison/   Daniel.Cardenas (talk) 20:18, 4 July 2014 (UTC)

Early testing of a RK3288-based device performed in late August 2014 shows clear evidence that the RK3288 has Cortex-A12 cores. It appears Rockchip is intentionally overstating the specifications of the RK3288, despite the fact that Rockchip themselves had earlier described the cores as being Cortex-A12. The Cortex-A12 is not much slower that the Cortex-A17, but apparently Rockchip is sensitive about the lower number potentially negatively affect its marketing. "Lying" about specification is not uncommon in China (see also Actions Semiconductor's ATM7029 chip). Calamites (talk) 09:57, 19 September 2014 (UTC)

Following feedback from User:Popolon, the article has recently been updated to reflect a recent decision by ARM. Although RK3288 technically contains ARM Cortex-A12 cores, ARM has abandoned the name Cortex-A12 and allows it to be called Cortex-A17, just like the "real" Cortex-A17 core, since the latest production revision of Cortex-A12 has a similar performance level as Cortex-A17. It is likely that Rockchip has been one of the few, or only, major chip company that has adopted Cortex-A12 (tied to GlobalFoundries 28 nm HKMG process, for which there are few other customers).

High Efficiency Video Coding (H.265)

RK3288 is supposed to contain Semiconductor intellectual property core capable of video acceleration of High Efficiency Video Coding (HEVC, H.265). It would be nice to get more information about this. E.g. Broadcom Crystal HD, PureVideo, Unified Video Decoder, Quick Sync Video have all their distinct articles. We could write such an article for the Rockchip video acceleration module, or at least a section in this article. But it would need a name, such e.g. CedarX and of course information. Personally, I am interested in Linux support. User:ScotXW^t@lk 16:33, 28 June 2014 (UTC)

Merger proposal

I propose that Rockchip RK3288 be merged into Rockchip. I think that the content in the Rockchip RK3288 article can easily be explained in the context of Rockchip, and the Rockchip article is of a reasonable size that the merging of Rockchip RK3288 will not cause any problems as far as article size or undue weight is concerned. Prunk (talk) 11:26, 8 December 2015 (UTC)

I think there is lot to say about this SoC, the number of device that used it, including for the first time in the history of Rockchip, some laptops by vendors like Asus, the changes in the politics of Rockchip that started to actively work on mainline Linux kernel with it, instead of having it's own repository before, about the A12/17 story, this processor meet a good reception in news due to its good performances. The next chip (firts arm 64 bits) reuse lot of things from this one. I worked mainly on french wikipedia article on this points.Popolon (talk) 19:25, 8 December 2015 (UTC)

Ditto the above. The are many precedents such as the individual pages for the Intel CPUs. Over a year and no movement on this I'm removing the merger request. — Preceding unsigned comment added by Bostwickenator (talk • contribs) 18:13, 29 December 2016 (UTC)

Linux SDK Wiki is gone

Sadly, it seems the Linux SDK wiki is gone. Does anyone know why? It still exists on the internet archive at: https://web.archive.org/web/20200620232346/https://opensource.rock-chips.com/wiki_Linux_SDK

Would update the links, but I don't know if it is irrelevant now if everything Linux-wise has been mainlined. Hamishtmb (talk) 15:58, 27 May 2022 (UTC)
