ARM’s Cortex A72 mobile processor can blast out 4K video at 120 frames per second

In the constant war for more processing kick in our mobile devices and PCs, chip makers across the board are developing their own new CPUs and GPUs for mobile devices and other computers and their 4K ultra HD graphics needs.

Now, chip manufacturer ARM won a major victory in this race by coming uot with a new SoC (system on a chip) processor that is supposed to be the most powerful of its kind yet built.

More specifically, the new chip can handle 4K media and graphics at an astonishing 120 frames per second.

We’re talking about the new Cortex A72 processor and man does it ever come with some heavy duty video management power! This bad boy can record 4K video at a whopping 120 frames per second and offers an overall 50X performance increase from any leading smartphone built 5 years ago. It’s even 3.5 times more powerful than the Cortex A15 line from the same company, which is currently found in the already powerful Galaxy S5 phone.

To appreciate what this leap in 4K video rendering capability means, understand that this small processor, designed for mobile devices, now offers and ultra HD video frame rate that isn’t found in virtually any full-blown consumer-grade or even prosumer 4K video camera. Even many of the high-end professional video production cameras with 4K video recording rarely offer 4K video at more than 60 fps and many of these toys cost thousands of dollars.

The processor receives a further internal boost thanks to a Mali T880 GPU which offers a “console-like” processing capacity for mobile devices. In other words, 1.8 times more performance power than any other chip being put into mobile devices today. The T880 GPU also supports 4K content by itself, natively.

These amazing and sudden performance increases are possible thanks to a new chipmaking process that involves building the internal parts of the processor at a tiny 15nm FinFET scale.

Furthermore, the new A72 chip offers dramatically improved energy efficiency by consuming 75% less power than any 2014 chip when working under matching performance conditions.

Unfortunately, don’t hold your breath on buying a phone with the AMD Cortex A72. This powerhouse chip is supposed to be the benchmark processing technology of “multiple generations” of smartphones, but only as of 2016.

    “Console-like” power can be anything. Gamecube? That came out in 2001. PS3? That came out in 2006.

    One thing I’ve noticed with handhelds (both gaming handhelds, and smartphones) is that they tend to be roughly 8-10 years behind current consoles and PCs. For example, the Super NES was released in 1991. The Gameboy Advance was released in 2001 and had roughly Super NES-quality power. The Nintendo 64 was released in 1996. The Nintendo DS was released in 2005, and had roughly Nintendo 64-quality power. Likewise with mobile phones, whose power can be matched roughly to around console and PC power was ~10 years ago.

    So if mobile phones truly have the quality of graphics of an Xbox 360 (released in 2005), that would actually be really good, but still not “modern console” power.

    And this is ignoring the whole “sticks and buttons” problem of mobile phones. Even my nephew, when he was 4, complained about the iPad’s Rayman Jungle Run not having the gameplay of Rayman Origins.
