Qualcomm makes all kinds of chips, with different production lines, of course. (He mainly designs the core of the chip, not produces it.)
The famous Snapdragon processor is a representative product of Qualcomm, which is designed and handed over to Samsung and TSMC, because they may be the most comprehensive capability in the chip field today.
So Qualcomm's various chips have different product lines. Such as MSM, APQ these are the models of the Snapdragon processor series zhi, MSM is an all-in-one processor that contains daoAP, BP and other components, APQ is a processor without baseband.
MDM is a product model of the Gobi series, which is a separate modem and also a baseband chip.
Qualcomm is very comprehensive, high, medium and low-end, like the Snapdragon 805 series, which is one of the strongest chips at present. The Snapdragon 200 is the absolute low-end goods.
Both Qualcomm and Mediatek are chip makers. The performance of its chips can not be generalized, depending on the specific model of the chip. Mediatek focuses on the middle and low end, and the current eight-core MT6592, the strongest performance, is also medium performance
