Recent summary of some new chips used by Alibaba Cloud (updated rk3066)

From: http://bbs.imp3.net/thread-10691814-1-1.html

Chip name	Keyou	Pre-market promotion frequency	Maximum frequency of production machines	Maximum frequency	GPU	Remarks
Rk3066	Original path Cobi cube	1.4 GHz * 2	1.6 GHz * 2	1.6 GHz * 2	Mali 400mp4 @ 266 MHz (Old firmware) Mali 400mp4 @ 399 MHz (Latest firmware)	Features: High Frequency The founder of Zichang virtual mark frequency was very calm this time. From the rk2818 era, the virtual mark of 624mhz was set to 660 MHz and the 918 MHz of rk2918 (and the kernel is displayed as 1008 MHz by modifying the kernel) the Virtual Scale is 1.2 GHz, and the scale of the Virtual Scale is increasing. This rk3066 nominal 1.4ghz aroused the curiosity of netizens-will the clock speed eventually run at 600 MHz or MHz? The result is rk30 ......
Jingchen Semiconductor Aml8726mx	Blue Magic	1.5 GHz * 2	Default maximum frequency: 1.2 GHz * 2 Particularly adjusted to High-Performance Mode: 1.32 GHz * 2 (7-inch host) 1.5 GHz * 2 (9.7 inch host)	1.5 GHz * 2	Mali 400mp2 @ 333 MHz	Features: cheap The main advantage of this controller is that it is cheap, and the price of the tablet with this controller can be very low, in addition, this product has flash hard decoding (that is, videos embedded in Flash such as Youku and Tudou can be hard solved, so they can be viewed smoothly on the webpage). AML also has many years of experience in set-top boxes, although it is the same as the decoding of the 1080p specification, this solution has better compatibility, so the price should be MP4.
New coastline Ns2816m	Aike	2.0 GHz * 2	1.2 GHz * 2	1.2 GHz * 2	Mali 400mp2 @ 400 MHz (The most popular MP2 mali400 after aml mx gpu frequency reduction)	Features: High-frequency GPU This main control has been publicized for a long time. It seems that after NVIDIA came out, it has been vigorously publicized. It seems that after more than a year, there has finally been a finished product, and there is only love.
Flisikar I. mx 6 quad	Chi Wei	1.2 GHz * 4	1.2 GHz * 4 1.0 GHz * 4 (Some products use this frequency to save power)	1.2 GHz * 4	Gc2000 @??? MHz	Features: quad-core This is the use of the new tablet launched by Chi Kai recently. Based on the current intelligence, the performance is very strong. Although the GPU is also very strong, it is a bit unpopular.
Lianfa Branch Mt6575	Lenovo	1 GHz	1 GHz	1 GHz	Powervr sgx531 ultra @ 522 MHz	Features: Cortex-A9 architecture, huge cheap, public edition firmware are very mature (inherent characteristics of the subject), High Integration MTK has always been the main shanzhai, the new chip launched in February using the Cortex-A9 architecture, the same frequency than the A8 on the 25%, in addition, the sgx531 is adopted with a frequency of up to MHz to the limit (the GPU performance is equivalent to the sgx540 of the default frequency, as shown in the table below ), the overall performance is basically the same as that of Samsung hummingbird, The 1.2ghz high-frequency edition known as A8, which is the strongest.
Quanzhi A ??	Onda	?? GHz * 4	?? GHz * 4	?? GHz * 4	Mali 400mp? @??? MHz (A lot of resources are available after authorization)	Features: Unknown It is said that the Cortex-A7 architecture, the same frequency performance is slightly lower than A8, the main performance ratio, multi-core performance can increase I heard that quanzhi will skip dual-core and directly build a quad-core architecture. At present, it is calm and will repeat the Reverse Attack that went public when the chip was released last year and a mass production machine was released? Chip name is also the object of many netizens guess, considering the current arm's highest-order chip architecture for Cortex-A15, this chip will be named A16? In addition, we are very much looking forward to the support of 4320p ultimate HD hardware solutions for the next generation of products!

 

About Mali 400, recently used a lot of manufacturers, because arm bound this with the Cortex-A9 authorization, the villagers in order to save money to buy this by the way, this thing can be said to support multi-core, in fact, we can see that there are only one pixel processor and one vertex processor, so the performance is like this (some data is for personal speculation ):
After thinking about it, I 'd like to add an industry benchmark apple comparison:

Chip	GPU	Polygon Generation Rate	Pixel filling rate	Floating Point computing capability
Apple a5x	Powervr sgx543 mp4@ 250 MHz	130 mtri/s	4000mp/s	32 gflops
