Qualcomm names all of their Snapdragon chips just numbers, but they are usually hard to tell apart. The only way to distinguish between them is the first number, 400, 600, and so on means a different series. However, two Snapdragon chips will now be renamed to make them “easier” to tell apart.
The Snapdragon 618 will be changed to 650, and the 620 will now be known as the 652. The reason for this change is to separate these two chips from lower-end ones in the same line.
Since the announcement of the Snapdragon 620 earlier this year, we’ve added a number of processors to the 600 tier including the 615, 616 and 617. The Snapdragon 620 and 618 processors stood out however, with their use of our advanced X8 LTE modem technology with Cat 6 support and carrier aggregation plus the advanced ARM-A72 CPU and next generation Qualcomm Adreno 510 GPU.
The 650 and 652 feature 4K Ultra HD video capture, advanced X8 LTE modems with carrier aggregation support, and Cortex-A72 CPU cores. For these reasons, Qualcomm felt it was necessary to push them far ahead of the others in the 600 tier.
Currently, neither chip is being used in any smartphones or tablets, but Qualcomm says they will be soon.
