AnandTech | Samsung Galaxy S 4 Review - Part 1
Part 1 of the Anandtech review... You'll see why they're considered the holy grail of reviews by many. Great writing, supreme detail you get nowhere else, and tables upon tables. However, I found the processor part most interesting:
Very interesting. It's still billed as the S600, but is something slightly different than what everybody else is using. Maybe more light can be shed on this in the coming months.

That brings us to the Galaxy S 4. It's immediately apparent that something is different here because Samsung is shipping the Snapdragon 600 at a higher frequency than any other OEM. The Krait 300 cores in SGS4 can run at up to 1.9GHz vs. 1.7GHz for everyone else. Curiously enough, 1.9GHz is the max frequency that Qualcomm mentioned when it first announced Snapdragon 600.
Samsung is obviously a very large customer, so at first glance we assumed it could simply demand a better bin of Snapdragon 600 than its lower volume competitors. Looking a bit deeper however, we see that the Galaxy S 4 uses something different entirely.
Digging through the Galaxy S 4 kernel source we see references to an APQ8064AB part. As a recap, APQ8064 was the first quad-core Krait 200 SoC with no integrated modem, more commonly referred to as Snapdragon S4 Pro. APQ8064T was supposed to be its higher clocked/Krait 300 based successor that ended up with the marketing name Snapdragon 600. APQ8064AB however is, at this point, unique to the Galaxy S 4 but still carries the Snapdragon 600 marketing name.
If we had to guess, we might be looking at an actual respin of the APQ8064 silicon in APQ8064AB. Assuming Qualcomm isn't playing any funny games here, APQ8064AB may simply be a respin capable of hitting higher frequencies. We'll have to keep a close eye on this going forward, but it's clear to me that the Galaxy S 4 is shipping with something different than everyone else who has a Snapdragon 600 at this point.
Very interesting. It's still billed as the S600, but is something slightly different than what everybody else is using. Maybe more light can be shed on this in the coming months.
