ARM is Already Considering 128-bit Mobile CPU

Earlier this year, Apple made headlines with its 64-bit SoC for the iPhone 5S. That SoC is now present in the iPad Air and the new iPad Mini Retina. Since the launch of the iPhone 5S, we've been hearing talk of a 64-bit Exynos from Samsung. Now ARM has confirmed that the chip is coming. The Korea Herald cites a senior manager at ARM as saying executives from Samsung and ARM met this week and discussed the ARM 64-bit chip expected to be used in a Samsung device next year.

Though it's not an official confirmation, rumors of a 64-bit Samsung device have been doing the rounds for a while. Word on the street is that the Galaxy S5 will include a 64-bit processor. No doubt if Samsung does include the 64-bit Exynos in the S5, we'll also see it in the next iteration of Galaxy Note as well.

Of course, with the rate at which mobile technology is evolving, it's hard to think about what's next without thinking about what's going to come in the future. To that end, it sounds like ARM is already considering a 128-bit processor. According to the KoreaTimes' ARM official, such a chip could hit the market in the next two years, but it's not set in stone.

    i would say more than overkill, 64bit already qualifies for that status

    128 bit is a little bit (pun not intended) overkill

    I much rather have this than pointless, battery eating, gpu sucking 1440p mobile displays...

    There is a difference between a CPU that can handle 128bits data structures a CPU that can do all arithmetic operations using 128bits operands. With AVX2, x86 can already work with 256bits registers and AVX3 will extend that to 512bits but most arithmetic using those are limited to 64bits int/float.

    I'm guessing ARM's 128bits will be similar: provide more register bits to work with SIMD and add a subset of instructions that can actually work with 128bits values.
