AMD's plans for 2014

DigiTimes has put together an overview of AMD's plans to take back market share over the coming year, though of course AMD is not confirming or denying the accuracy of their report.  First off will be the coming of the 28nm Kaveri family in January with availability planned to follow quickly.  Beema, which will be based on the Puma+ architecture should arrive in the summer but there is also a Kabini-based series for the new socket, FS1B, which will get limited release in some areas.  FS1B will be used for up coming Sempron and Athlon models designed for low power usage scenarios though don't expect to see AM3+ or FM2 disappear any time soon.  You will have to wait for 2015 before Carrizo and Nolan make an appearance.

"AMD has been enhancing the marketing of its processors in DIY markets and aims to increase its global DIY market share from about 30% currently to 40%, and to reach a DIY market share above 45% in China in particular, at the end of 2014, according to Taiwan-based motherboard makers."

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.

AMD's unannouced 2014 roadmap

Subject: General Tech | August 27, 2013 - 12:30 PM |
Tagged: amd, roadmap, 2014, Kaveri, Kabini, carrizo, beema, Excavator, Nolan, 2015, socket sf1b

As is usually the case, AMD will not comment on the accuracy of DigiTimes information but as we have seen in the past their roadmaps have been spot on.  Over the next 8 months or so will see the arrival of the Hawaii GPU family and the entrance of Kaveri and Kabini chips, nothing new there but good to have independent confirmation.  In the latter part of 2014 and 2015 things are a little more interesting as Beema will replace Kabini with an HSA compliant architecture and use a new socket called FS1B.  In 2015 Beema will be replaced by a chip called Nolan and we will finally see the Excavator based Carrizo which are slated to have 45W and 65W versions.

You can expect to see FM1 and AM3 phased out of active production by the end of 2013, with AM3+ and FM2 being the two active sockets until FS1B arrives.

"AMD has recently updated its product roadmap and is set to release its Hawaii-based GPUs at the end of September, Kaveri-based APUs for the high-end segment and Kabini-based APUs for the entry-level segment in the first quarter of 2014, according to sources from the upstream supply chain."
