As expected, Chinese chip maker MediaTek has unveiled its first 8-core, 64-bit processor for smartphones. But that’s not all. The company has also revealed that it’s new chips can support super slow motion video recording and high resolution displays with fast screen refresh rates.

The MediaTek MT6795 processor is the company’s most powerful chip to date. It has 8 ARM Cortex-A53 CPU cores that can handle speeds up to 2.2 GHz, supports dual-channel 933 MHz memory, and screen resolutions up to 2560 x 1600 pixels.

The MT6795 chip works with 4G LTE networks and also supports 802.11ac WiFi, Bleutooth, GPS, FM Radio, and 2G and 3G wireless networks.

Other features include support for recording 1080p video at up to 480 frames per second for super slow-motion video playback, and support for displays with screen refresh rates of 120 Hz, thanks to a partnership with Japan Display. Most smartphone screens on the market currently top out at 60 Hz.

The chip also supports video recording and playback at Ultra HD (4K2K) resolution using the H.265 format as well as H.264 and VP9 formats.

Wondering why MediaTek isn’t using the more powerful ARM Cortex-A57 technology for this chip? The company is apparently saving that for an upcoming tablet processor.

In other words, MediaTek’s new chip will likely compete against Qualcomm’s upcoming Snapdragon 615 processor for mid-range devices instead of the Snapdragon 810 chip for high-end devices. But all of these chips will probably make whatever chip is in your current phone look slow (once mobile operating systems and applications are optimized to fully take advantage of 64-bit architecture).

MediaTek’s new chip could show up in phones by the end of 2014.

  1. This is something to look forward to. I hope that my favorite software video surgeon has the power operate this.

  2. Kinda scary how Meidatek, Allwinner and Rockchip almost caught up to Qualcomm in such a short time.

  3. It will be interesting to see what real world performance and power usage is for these chips. Using the 28nm size will put them at a disadvantage but cost has a way of leveling things out a bit.

  4. lol why does 90% of the press think that 64 bit means fast?
    It’s A53 based , the A53 replaces A7, it’s a small ,cheap and low power core and you won’t get any kind of crazy performance, just quite a bit more than an A7.
    No point in mentioning Snapdragon 810 either. That one comes later and on 20nm, this thing is on 28nm and that’s why no A57. Wait a few more months and you’ll see A57 on 20nm from them too.

    1. 64bit registers can often be used as 32bit registers, meaning you have twice the count. It is a very (very very) good thing for compilers since, right now, most of them can use that to generate code that store more data in the cpu registers, avoiding lots of RAM/cache access.

      1. 64 bit registers does NOT mean you have twice as many registers as you would with 32 bit registers. I know of no architecture that allows you to access just the high 32 bits of a 64 bit register and treat it as a separate register from the low 32 bits. 64 bit ARM just happens to have twice as many general purpose registers as 32 bit ARM does.

        1. Ha ? I thought it was an implicit feature, as in x86 AX = AH + AL, making this a free meal from having larger registers, I was wrong.

          Anyway, if ARM7 64bits really have 2x as many registers, the compiler optimization is still possible.

          1. The 64bit has no impact on speed. The important thing is, that the architecture is ARMv8. This is the reason why Apple A7 dual-core CPU is faster then any 8-core CPUs out there.

            So if MediaTek will make an 8-core ARMv8 CPU it will be a beast!

          2. Register count matters a lot. Probably a lot less than modern architecture but still it has an impact. See gcc register allocation/spilling and the difference between binary output.

    2. ‘crazy performance’ Eh, supposedly ARM named the A series for approximate performance relative to other cores, so A9 is slightly better than A8, A15 is roughly twice as fast as A8, A53 is… uh… maths times better than A7, quite a few I think.

    1. Yes … but 8 of the LITTLE cores rather than the big ones but 8 all the same, they have a similar one with Cortex-A7 cores, the MTK 6592

    1. I am impressed by the rate at which they churn out new SOCs covering a large swathe of the market …. now … If only they can work this hard at GPL compliance and *with* the community
