Snapdragon 800 (MSM 8974)

[A.k.a. "Snapdragon S4 Prime"]

Qualcomm has already started to roll out samples for their new Snapdragon
flagship SoC’s. Starting in mid 2013, we’ll start seeing new devices running
their new dragons. Thus it is important that XDA developer can keep up-to-date
on this development so that we can be quick to “help” both Qualcomm and the
carriers using devices, to develop for these products. Just in case they think
they need to re-invent the wheel by locking up their bootloaders and so on…

Please feel free to add or correct info posted in this thread.

Everyone is Welcome! (Especially Qualcomm)

Again AnandTech provide us with some useful and correct information.

The New Snapdragons

The new Kraits will find their way in new Snapdragon platforms, now numbered
200, 400, 600 and 800 (the old S1 – S4 labels are gone). As always, higher
numbers mean better performance but you’ll still need to rely on the internal
part numbers to know what’s really inside.

Today Qualcomm announced the Snapdragon 800, which implements four Krait 400
cores running at up to 2.3GHz, an Adreno 330 GPU and Qualcomm‘s 3rd generation
LTE baseband (9×25) all on a single die. Snapdragon 800 is the part formerly
(or still internally) known as MSM8974 which we’ve seen rumblings about
numerous times.

Qualcomm tells us that the Adreno 330 will offer roughly 50% more graphics
performance over Adreno 320, and an almost 2x increase in compute performance.

The integrated 9×25 3rd generation LTE baseband enables support for UE
Category 4 LTE with up to 150Mbps downstream, this is the same IP block as in
MDM9x25, and likewise MSM8974/Snapdragon 800 will be available in all the
usual variants (CDMA2000/WCDMA/LTE, WCDMA/LTE, and finally no modem).

Snapdragon 800 also integrates 802.11ac baseband, a new feature of modern
Qualcomm SoCs, just like 8960 and the previous S4 family.

Snapdragon 800 also includes a 2×32 LPDDR3 memory interface.

On the video/decode side, the SoC supports encode/decode of 4K HD content at
30 fps.

Also being announced today is the Snapdragon 600. This part integrates four
Krait 300 cores running at up to 1.9GHz. Adreno 320 handles GPU duties,
although with an increased clock speed. Compared to the current Snapdragon S4,
the 600 is expected to improve performance by up to 40% if you combine IPC and
frequency increases.

The new Snapdragon 600 is also known by the part Issue [SOLVED]” href=”http://en.samaanet.com/?p=8317″>number APQ8064T, and was
formerly known as the Snapdragon S4 Pro.

So here you can see that we will have a platform based on the following components:


PMIC:  8841/8941 (or 8851??)
RF:    WTR1605L
Audio:  WCD9320
Data:  WCN3660


This is already incorporated into their CodeAurora kernel GIT.
