If a new report is to be believed, Samsung is going to have dibs on the Snapdragon 845 for the Galaxy S9. It had a similar deal with Qualcomm this year as well for the Galaxy S8. Samsung manufactured Qualcomm's Snapdragon 835 processor and got to keep the initial batch for itself. That's why early this year there was no other Snapdragon 835-powered handset on the market other than the Galaxy S8.
It appears that this might be the case for the Galaxy S9 as well. Qualcomm might return to Samsung in order to get its new chip manufactured. If that happens, Samsung is likely going to want to keep the initial batch of the Snapdragon 845 for the Galaxy S9 and Galaxy S9+.
Dibs On Snapdragon 845 for Galaxy S9
There isn't a lot of technical information available about the Snapdragon 845 as yet. However, more information is expected to surface in the coming days.
As far as availability is concerned, the Galaxy S9 and Galaxy S9+ will likely be the first handsets to come with Qualcomm's latest chip. This means that rivals like LG would have to go through yet another flagship cycle without access to Qualcomm's latest chip.
Samsung is expected to release the Galaxy S9 early next year. There are rumors about the handset being launched a month earlier than usual. It's not uncommon for these rumors to come up before a new flagship's launch, doesn't mean that it's going to happen.
