ARM Cores Take On PC Processors

ARM is looking beyond smartphones to PCs with its new 64-bit Cortex-A72 processor core.

SAN FRANCISCO – ARM announced a new processor core, GPU core, and interconnect targeted for mobile SoCs. The 64-bit Cortex-A72 processor core, Mali-T880 graphics core, and CoreLink CCI-500 aim to power a new class of mobile devices that "serve as your primary and only compute platform."

While slim on specs, ARM promises that its Cortex-A72 processor will deliver 3.5 times the performance of its Cortex-A15 devices while consuming 75% less power. ARM says its Mali-T880 graphics cores are similarly impressive in generation-over-generation improvements supporting resolutions up to 4K pixels at 120 frames/second.

The new version of the cache coherent CoreLink provides twice the memory bandwidth and 30% more performance as a processor/memory interconnect than ARM's earlier version. It also supports ARM's TrustZone for secure decoding of video from a Mali core.

Re: Maybe for mobile
This is just a logical next step for ARM to invade the PC market. We've seen ARM-based PCs for some time already, but they really need to offer enough horsepower to use dazzling applications.

Is ARM there yet? I think that the platform is getting close, but it almost seems as though they are being held back by the likes of Intel and Microsoft.

What prospect for ARM in the cloud?
Andrew Feldman, corporate VP of AMD, said at the OpenCompute Conference 2014: "By 2019, ARM will command 25% of the server market." That's an optimistic prediction. Use of ARM servers is still extremely limited, I believe. What would help the prediction is if cloud vendors decide thjere are long term savings in converting to ARM.

Mobile devices need more battery life
Offering 3.5 times the performance while consuming 75% less power is a winning combination. Such ARM chips would be great in phones, tablets and small laptops. In the mobile device, battery life is almost as important as processing power.

Maybe for mobile
It's good to see ARM continuing to push the envelope on mobile performance. I'm particularly impressed that Oculus is interested in its development.

However performance wise, I don't see this holding a candle to Intel's desktop efforts. It's been king of the hill for the best part of a decade now and doesn't look likely to lose that crown any time soon.
