With things moving at a surprisingly fast pace in the mobile chipset world, ARM had recently revealed that the company had the Cortex A72 under development, which would offer several new advancements over its current Cortex A57 top dog. One of these would be the ability to record 4K video at slo-mo, ensuring that you don’t end up missing any detail at all. Well, the company’s laid out comprehensive details about the A72 today, and gone as far as to compare it to Intel’s Core M, a processor that’s recently been making quite a lot of rounds.

 

 

ARM’s latest Cortex A72, as expected before will be manufactured on the 16 nm node. The processor core has several advancements on board, which include a 75% increase in efficiency over its Cortex A15, launched by the company nearly 4 years back. But while earlier products from the company have focused mainly on smartphones and mobile devices, looks like ARM’s moving more towards low power demanding ultrabooks as well. Apart from detailing the Cortex A72’s specifications today, the company has also stacked its latest against Intel’s Core M.

 

 

As can be seen above, so confident is ARM in its Cortex A72’s abilities, that its gone straight ahead and compared it to Intel’s Braodwell. While Broadwell really is no match when it comes to complete power packed performance, restrict both thermal envelope and power, and you’ll see the chip make some gains. These can be seen above, with the Cortex A72 going head to head against Core M. There’s also been word about it being used in more than mobile devices, so we’ll have to wait until the A72 becomes available, which is next year, in 2016.

 

 

ARM has been more impressive than usual as of late. Not long ago most thought ARM would be extinguished by x86 although it's looking like they have a lot of fight left in them. Impressive to reach near Core M performance at under a 1w envelope in a market where not just performance matters but also power efficiency.

I trust these guys over wccftech, they've been around a really long time.

I think the biggest news here is that A72 will use less power than A57 on the same processing node.20% reduced power consumption at the same manufacturing processor and clock speed is pretty sweet. On top of that we get IPC as well (seems to be about 20% increase on average).

A lot of the numbers from ARM are kind of misleading because they compare it against A15 which is now 4 years old, not A57 which is their latest architecture. They are also comparing A15 on 28nm vs A72 on 16nm. Just something to keep in mind when looking at some of the numbers. A72 seems like a pretty good upgrade from A57. More performance for less power is always good news.

I've read the huge article the other day, ton of info

Head over to the anandtech article, they included the A57 in the charts.

What I'm curious about is how Qualcomms Snapdragon 620(A72+A53) will preform compared to the Snapdragon 820(Kryo).

Qualcomm had the edge over stock ARM designs with Krait up until the A57 launched, will be interesting to see what they can do.
