Qualcomm Snapdragon 800 and 801: what are and what is the difference?

In 2013, the company Qualcomm, a leader of the modern 

market processors for mobile devices , today announced the new top 805 Snapdragon chip , promising to release it in 2014. However, in the first quarter of this year, almost all major smartphone manufacturers announce recent flagship, which, of course , can not be equipped with a Snapdragon 800 , because it is already installed in most of autumn " monstrofonov ." 

Therefore appeared Snapdragon line 801 , some members of it have the same indices as the previous . So what do they really differ ?

Anand Shimp (Anand Lal Shimpi) in his blog AnandTech has published an excellent article for those who are aware of appearance Snapdragon processor line 801 , but could not understand what she was better than the previous generation , the current champions for the autumn . Probably should start with a list of all modifications for each type of chips.

800 Snapdragon lineup consists of three processors : MSM8974VV, MSM8974AA and MSM8974AB. Connects them all several important factors : the second version of SoC, support for eMMC 4.5 and the absence of the concurrent operation of two SIM. It is for these items Snapdragon 800 and 801 differ from Snapdragon . Fresh version of the flagship chip from Qualcomm boasts the third version of the layout SoC, increased frequency of ISP, support higher speed eMMC v5 and the possibility of simultaneous work with two SIM-cards. 801 -series also consists of three chips : MSM8974AA, MSM8974AB and MSM8974AC. As you can clearly see , the numbers of two processors in both product lines coincide, which leads to confusion .

Moreover, MSM8974AA frequency of the CPU, the accelerator , the memory bus and ISP ( module responsible for most camera functions ) of Snapdragon 800 is identical to those in the 801- m Snapdragon , differences lie here in the very key points described above. This reckoning last year many partners Qualcomm chip MSM8974AC to 800 series , prove that in front of us , only a small refinement , for marketing purposes allocated to a separate line . In general, the Snapdragon 800 and 801 are identical to four core Krait 400 accelerator Adreno 330 and LTE- line modems 9 × 25.

However , the emergence of Snapdragon 801 was really necessary Qualcomm partners in order to make a large part of people chasing for a new "iron" , buy fresh flagships . In this case, the U.S. chip maker not only satisfied the commercial interests of the partners, but also pleased geeks shoppers.
