MediaTek’s most exciting next-gen chip is the upcoming 7nm Arm Cortex-A77 processor with integrated support for 5G wireless. But we probably won’t see devices powered by that chip until early next year.

The chip maker has another new processor on the way though — the MediaTek Helio P65 is an upcoming octa-core processor that features two Arm Cortex-A75 CPU cores and six Arm Cortex-A55 CPU cores.

It also packs a new neural processing unit that MediaTek offers twice the AI performance of its earlier chips. But in some ways the MediaTek Helio P65 seems like a downgrade from the older Helio P60.

For example, the new chip features Arm Mali-G52 graphcis rather than the higher-performance Mali-G72 GPU. So 3D graphcis performance likely won’t be as good.

And while the Helio P60 sported less-powerful Arm Cortex-A73 and Cortex-A53 CPU cores, it had four of each (instead of 2 and 6), so you can probably expect better single-core performance from the new Helio P65, but lower multi-core performance, depending on the tasks.

The Helio P65 also lacks support for dual-channel memory and UFS storage, both of which are present in the Helio P60 and Helio P70.

All of which is to say… I doubt that MediaTek expects this chip to replace its predecessors. Instead it’s likely to help round out the company’s lineup of chips for mid-range smartphones.

  1. mali g52 is 30% more powerful than adreno 618 found in snapdragon 730. i just heard that. for multitasking and gaming its a beast

  2. Multi-thread performance is one thing, real-life multi-process performance is another. The new Cortexes, starting with the A75 and the A55, make it possible to run both the big and the little cores at the same time, whereas the A73/A53 have an exclusive operation. So when a heavy task starts, the two A76 will be activated while the A55 will still run other, background tasks and less heavy threads.

    1. My understanding is that such a thing has been possible for several years. I remember Heterogeneous Multi Processing(HMP) was planned but broken on the old Exynos 5410, but worked correctly on the 5420. As I recall, what the A75/A55 products allowed was more flexibility in core layout, no longer being limited to banks of two or four CPU cores. This means we can see SoCs with odd layouts like five small and three large cores, in theory.

      1. You’re exactly correct.
        A Cortex A73 and Cortex A53 are the slower counterparts to say Cortex A76 and Cortex A55. But a 4+4 slow soc can/will still beat out a 2+6 fast soc because of the big discrepancy between the Big Cores vs Small Cores. And the Helio P65 is going to have a decent A75/A55 but far from the best implementation. And because of this reason, we can safely say it will be slightly slower than the old Helio P60.

        But for one thing, it will be more efficient.
        The only thing better would be to use a future 1+7 setup with an overclocked Cortex A78 and underclocked Cortex A58 on a Samsung 5nm lithography, that could maintain performance whilst stretching efficiency far.
