ARM's new efficient Cortex-A35 core might end up employed inside wearables

ARM's new efficient Cortex-A35 core might end up employed inside wearables
On the heels of introducing its Mali-T470 GPU that will crunch graphics for wearable devices, ARM has introduced the ARM Cortex-A35 core that can be used for the wearables market. It is designed to be used in devices where not that much processing power is required. The new core is part of a low power consumption tier that ARM calls "Ultra High Efficiency."

The Cortex-A35 is 25% smaller than the Cortex-A53, and uses 32% less power than the latter. Overall, it is 25% more efficient. Which means that we co could see the Cortex A-35 replace the Cortex A-53, the Cortex-A5 and Cortex-A7. Compared to the Cortex-A7, the new core uses 10% less power, with a 6% to 40% improvement in performance. It can be used in conjunction with the Cortex-A72, Cortex A-57 or Cortex-A53 in a big.LITTLE designed chipset where it would be handling the less imposing tasks.

Parts of the Cortex-A35 are even newer than what you will find on the Cortex A-72, which is why the new core is so power efficient. The first devices to employ the Cortex-A35, whether a smartwatch or a new handset, will be rolling off the assembly line in 2016.

Good stuff

A72 + A35 Big little wombo combo setio wouldn't be that bad right?

I doubt a35 cores will have enough processing power for even light tasks in a phone OS.

PhoneArea missed lots of important info, from the AnandTech While both at the same frequency and 28nm process The A35 can "match the A53's performance from 80% to up to 100% depending on use-case" "The A35 is able to achieve all of this at 75% the core size and 68% the power of the A53"http://images.anandtech.com/doci/9769/a53-comp.PNGhttp://images.anandtech.com/doci/9769/config.PNG So it seems like 14/16nm A35s would definitely be more than power enough IMO its highly likely Qualcomm's 630 or 430, and the next flagships from MediaTek and Kirin will use A72s+A35s

I think Mediatek can try A72+A53+A35 10-12 core configurations for high-end and 8 core A35 for low end.

Probably a 10-12 core with A72s and A35s at different clockrates/voltages If ARM's claims are true, IMO there's not really point using A53s when you could probably use A35s with a slightly higher clockrate IMO we will see the A35 replacing the A53, until the A53's true successor comes See my comment below for the supposedly leaked roadmap

One of the graph shows 40% better perf than A7 at Geekbench. We know that Mediatek's new mid-range chip Helio P10 coming with 2GHz A53 by end of the year or early 2016. To matching its Geekbench scores A35 should be clocked to 2.4GHz and matching P10 won't be enough for its successor. It needs to be faster lets say about 25%. So we are talking about 3GHz clock speeds. Honestly I don't know whether or not it's possible for 28nm. Even if it isn't they could make it possible with FD-SOI from Samsung or Global Foundries, but chipmakers doesn't seems like inclined to FD-SOI yet.

That Helio P10's A53s would probably be built on 28nm HPm or 20nm/newer AFAIK all A7s have been built on 28nm LP or older So its not apples to apples The closest comparison is the A35 to A53 while same clockrate and process Where its "within 80-100% performance" while "using 68% power" We need to wait for benchmarks Personally, I wouldn't be surprised if a 2.2GHz A35 outperformed that 2.0GHz A53, since the A53 is a design from 2012 after all I too would like to see some SoCs built on FD-SOI

Decacore setup helio x25 High performance: A72 x2 Power/Efficiency: A53 x4 Ultra Efficiency: A35 x4

It shows better performance than A7, which is good enough for basic tasks. But yes, A53 would be the better option for big.Little.

If the A7 did (which it did, as it was the LITTLE component in the exynos SoCs before 7 octa), then this will too. If it cam be clocked high enough, it may be an alternative to the A53s in the big.LITTLE setup, while shifting the A53s to the big function. It'll only really be good enough for stuff 1080p and below, though. Built on a 20nm or 28nm HPL process, this could be great!

No more big.LITTLE please

I'm not a fan of BIG little configuration either. Manufactures should either go with Apple's approach of two high power cores or use four slightly lower cores.

four custom cores was always my ideal.

Why should manufaturers go with Apple's approach? big.LITTLE has proven to be great. Especially with the ones in Samsung's Exynos, which can use all 8 cores simultaneously.

which also overheats, but nobody cared because they were busy hating SD 810.

Also its been officially confirmed that the A35's codename was Mercury, which could mean this supposed leaked roadmap is truehttp://www.fudzilla.com/images/stories/2015/April/ARM10nm.jpg The roadmap suggests we will see an A53 successor codenamed Ananke and an A57 successor codenamed Artemis later Sourcehttp://www.fudzilla.com/news/processors/37583-arm-10nm-and-16nm-finfet-cortex-designs-leaked

my next phone should have A35 x 4... I'm currently using A7 x 4 and I am getting 7 hours of on screen time and the phone only gets hot when I use ( play a casual game or watch a video) and charge it at the same time. call me crazy but this is all I need
