AMD Releases 2014 Mobile APU Details: Beema and Mullins Cut TDPs

AMD’s APU13 is all about APUs and their programming, but the hardware we have seen so far has been dominated by the upcoming Kaveri products for FM2+.  It seems that AMD has more up their sleeves for release this next year, and it has somewhat caught me off guard.  The Beema and Mullins based products are being announced today, but we do not have exact details on these products.  The codenames have been around for some time now, but interest has been minimal since they are evolutionary products based on Kabini and Temash APUs that have been available this year.  Little did I know that things would be far more interesting than that.

The basis for Beema and Mullins is the Puma core.  This is a highly optimized revision of Jaguar, and in some ways can be considered a new design.  All of the basics in terms of execution units, caches, and memory controllers are the same.  What AMD has done is go through the design with a fine toothed comb and make it far more efficient per clock than what we have seen previously.  This is still a 28 nm part, but the extra attention and love lavished upon it by AMD has resulted in a much more efficient system architecture for the CPU and GPU portions.

The parts will be offered in two and four core configurations.  Beema will span from 10W to 25W configurations.  Mullins will go all the way down to “2W SDP”.  SDP essentially means that while the chip can be theoretically rated higher, it will rarely go above that 2W envelope in the vast majority of situations.  These chips are expected to be around 2X more efficient per clock than the previous Jaguar based products.  This means that at similar clock speeds, Beema and Mullins will pull far less power than that previous gen.  It should also allow some higher clockspeeds at the top end 25W area.

These will be some of the first fanless quad cores that AMD will introduce for the tablet market.  Previously we have seen tablets utilize the cut down versions of Temash to hit power targets, but with this redesign it is entirely possible to utilize the fully enabled quad core Mullins.  AMD has not given us specific speeds for these products, but we can guess that they will be around what we see currently, but the chip will just have a lower TDP rating.

AMD is introducing their new security platform based on the ARM Trustzone.  Essentially a small ARM Cortex A5 is integrated in the design and handles the security aspects of this feature.  We were not briefed on how this achieves security, but the slide below gives some of the bullet points of the technology.

Since the pure-play foundries will not have a workable 20 nm process for AMD to jump to in a timely manner, AMD had no other choice but to really optimize the Jaguar core to make it more competitive with products from Intel and the ARM partners.  At 28 nm the ARM ecosystem has a power advantage over AMD, while at 22 nm Intel offers similar performance to AMD but with greater power efficiency.

This is a necessary update for AMD as the competition has certainly not slowed down.  AMD is more constrained obviously by the lack of a next-generation process node available for 1H 2014, so a redesign of this magnitude was needed.  The performance per watt metric is very important here, as it promises longer battery life without giving up the performance people received from the previous Kabini/Temash family of APUs.  This design work could be carried over to the next generation of APUs using 20 nm and below, which hopefully will keep AMD competitive with the rest of the market.  Beema and Mullins are interesting looking products that will be shown off at CES 2014.

Double performance per watt of Temash/Kabini with updated GCN graphics plus Mantle accleration?

Might this phoronix article be related to the cryptographic co-processor?

It has to be related...

I am super excited about AMD's amazing APU's! The GCN on the apu's is amazing just by itself but improving both GPU and CPU aspects is gonna be killer! I know intel has kicked butt with CPU over AMD but GPU on and SOC goes to AMD hands down. I can not wait for AMD to get a SOC for the high end market that is gonna be a game changer for me considering I am running a Bulldozer haha! I do have a 780 GPU but I would like to shut that off sometimes and just use integrated for power savings. Keep up the good work at PC Per!!!

Yes, but AMD's new wireless display tech will only be supported for windows 8, 8.1, and no Linux(1)! Better watch out AMD, because gaming is coming to Linux, and you better offer top grade Linux driver support, for all of your new technology, or you will become a company that only supplys x86 CPUs for the gaming console makers, I do like Intel, much, but I have absolutely no love for M$! Do not let TIFKAM take you down the drain with it! Nvidia may be the only option for STEAM OS, and gaming without M$'s grubby little hands all over the pie!
