I thought so, but folks here asserted I was wrong. This should be the new chip with smaller fabrication. Still does not mean the US will see a S4 refresh with it.
Update:
Yep, as thought- it is a the new chipset I mentioned. Lower fabrication and faster chipset. The 600 is the same fabrication and design structure as the dual core in the S3. The 800 is the real deal change for the chipset family.
Still, if there is an S4 refresh with the 800, not too likely the US sees it, so probably the Note 3.
