Two ARM A15 cores can outperform four Cortex A9 cores

Written by Fuad Abazovic


28nm dual A15 beats Nvidia’s 40nm quad-core
We just had a nice chat with some chaps from Texas Instruments, the people behind the highly successful OMAP architecture, and we can tell you that 28nm can be very interesting for tablets and phones.

Unfortunately for consumers, 28nm comes only in 2012, for most companies in the latter part of next year, but it will get ARM chips quite a significant performance boost. We just heard that two new ARM 15 cores are fast enough to beat quad-cores based on the current A9 design. This means that a dual ARM A15 chip can beat Tegra 3, aka Kal-El, a 40nm quad-core solution. Kal-El is expected in Q3 2011, in August / September timeframe and it will be a while until you see 28nm ARM chips in actual products, which should appear roughly a year later.

This kind of performance will probably put a lot of pressure on Intel and AMD, companies who traditionally don’t know how to make chips that deliver ultra low power consumption, and it doesn’t stop there. In 2013 you can expect some 20nm chips to continue the transition.

Bear in mind that in 2012 we will see Windows 8 as well as Ice Cream Sandwich, Google’s OS that units a phone and tablet OS. Ice Cream Sandwich might come very late 2011 and it is promised to make a huge difference in the way users interact with tablets, phones and similar devices.

Of course, by the time Omap 5 and ARM A15 comes out, Nvidia should have Wayne A15 based 28nm as well.

2012 seems to be quite interesting year for tablet wars, as 2011 just kindled things up.

Well I hope so given that ARM now expects to compete in the desktop and server market.

That´s why Tegra 3 will suck.

Moki is right.. Kal-El will suck.. battery. It's going to be far too power-hungry. 4 cores at 40nm, with 5x GPU performance? Sorry Nvidia, that's just silly.

I doubt that. Have you seen the Kal-El demo?
Before i'm flagged as an Nvidia fanboy, i'm not.

So is it better to be a AM-DUNG beetle?!!

seen 2 demos of kal-el looks "nice" on a tablet fps games but power consumption is vital as always on mobile devices ..i`m happy if it will turn that arm a15 will be faster and not that power hungry ..i hope they will decide one day to invade desktop market even the low end or middle segment :)

This is the same scenario as HD6990M. Poorfags barking it's fastest mobile GPU.

No. If you have a basic understanding of SOC, you will know that a single SOC does not comsume as much power as you think.
Around 85% power is comsumed by monitor for a tablet / cellphone. And most of the Soc in market are less than 1W (or even half of that) in terms of TDP. So, no. Even KAl-El consumes 3 times of Tegra T250's power, it is still less than 2W.

And Moki is not quite right about soc either. Note that all of them are soc(system on a chip is not CPU) which uses ARM CPUs (Manufactures like NVIDIA,TI ..dont make CPUs, they buy the design from ARM. So the CPU are identical). Its similar to how different laptop uses different model of CPUs made by intel or AMD. so no, they dont suck. They just all have different market positions.

common sense should say that nvidia alreadly has the tech to put 4 arm 9 chips on 1 SoC, then they have the tech to put 4 ARM 15 chips on 1 SoC. . . or what ever ARM texas Instruments chip the like

Yes, basically similar to your idea here. It is just like how you place the CPU in different socket such as LGA775 socket 479 939 1156..etc..
But the biggest problem is that A15 is not yet released yet.The core is just taped-out not long ago and, if everything goes fine,will be released on late 2011.Thats why you see all the A15 related news have 2 keywords - "28nm" and "2012 tablet wars" (well some say late 2011. But Actual design will take longer time)
Thats why there are no A15 SoCs on the market yet.
