MediaTek's 10-core CPU & MT6797 SoC fully detailed, mass production to begin this Summer

MediaTek's 10-core CPU & MT6797 SoC fully detailed, mass production to begin this Summer
Taiwanese chipset maker MediaTek held an event to acquaint the press and its technological partners with its upcoming flagship SoC, the MT6797. As you may have heard already, this one pushes mobile CPUs into 64-bit deci-core territory, incorporating four ARM 1.4GHz Cortex-A53 cores for basic processing, four 2GHz ARM Cortex-A57 cores for middle to heavy usage cases, and two 2.5GHz ARM Cortex A72 for bursts of maximum horsepower.

The SoC, which is to be made on the ageing 20nm process, also incorporates an ARM Mali-T880 MP4 graphics chip clocked to 700MHz, good for encoding & decoding H.265 4K/2K video at 30 FPS, while powering up to 2560x1600 resolution displays. The chipset can handle up to 25MP camera sensors and comes with Native3D 2.0 technology for taking three-dimensional stills. The end result probably resembles the outcome of the Galaxy S6's Virtual shot mode.

A glaring weakness in an otherwise stellar spec sheet is the lack of LPDDR4 RAM support. The MT6797 is stuck with 993MHz LPDDR3 RAM, while Qualcomm and Samsung have already switched to fast 1600MHz LPDDR4 RAM. On a less relevant note, Qualcomm already has LTE Cat-9 support worked out, while MediaTek is on LTE Cat-6.

Otherwise, MT seems to be on a roll with this chipset, bringing very good performance potential at an affordable price to interested vendors. After all, MediaTek's silicon is quite an important factor in Chinese smartphones' famous performance-to-price ratio, so it's good to see the Taiwanese players keeping up with the top dogs while doing their part to advance mobile CPU technology. MT6797-powered smartphones should reach the market by this year's end.

Most stupid soc EVER .. 4x A72 andx 4 A53 would make sense, this is just plain stupid ..

MediaTek is master of marketing...3 cluster cpu in mobile soc is ridiculous and serve no purpose other than marketing advantage and lure dumb people! Simple 2/4 A72 core unit with async clock (I know arm design support sync clock) would've been more than enough. If MediaTek is so hell bent on wasting money they should create new in-order 4-wide cpu core based on A53(in-order 2-wide) design.

Good job MTK but disappointment with LPDDR4 RAM. Sammy is way ahead of the competition right now. Bang...

Except RAM support it seems quite good. Also I guess it's lack of UFS 2.0 support. They put it in 2 very powerful cores and a potent GPU. There is no need to be obsessive over core counts either way. There are interesting stuff in the imaging and video capabilities. Most certainly it will be cheaper than Qualcomm counterpart. Though it's timing a bit letdown.

One mistake in the article: ARM Cortex-A57 cores for middle to heavy usage cases, Should be ARM Cortex-A53 cores for middle to heavy usage cases, And good luck to Mediatek clocking the A72 cores at 2.5GHz in the 20nm without using FinFET. They will really need it in order not to have issues with thermal throttling...

All those cores will need incredible optimization... Too damn much going on... I wish an OEM could make a A72 custom super core, make it dual core and pair it with four A17/A53 custom cores or something... No particular reason, I just want to see it implemented or something LOL for the sake of nothingness...

this beast will be the real killer.. real battery killer... (70k+ antutu score i guess, but who care :-/) but its still nice if some brand put this in $400 phone :D

fandroids wants a 10-core-processor in a mobile phone, right? for bragging? forget the effect on battery life,, overly high specs like multi-core processors, 10gb ram, UHD screen are the ones that matter for gullible fandroids

I know right. 10 core CPU?!?! Even the most high end PC don't need that kind of power. This is pure bragging rights. And technophiles will still replace the phone after only 1 year.

Obviously you don't get it big.LITTLE.

f**k the big.little f**king architecture it's not good at all it was supposed to bring power efficiency but only thing i see is battery draining a quad core CPU was good enough.

so just because it has less core is should be more efficient? lol, big.LITTLE is more efficient than quadcore. Qualcomm just can't make it right because the are stupid.. lol.

I'd wait for some battery tests before making a judgement. Mediatek chipsets are known for their good battery efficiency.

Even if they add 100 more cores, a cheap and low performing processor will always be a cheap and low performing processor.

And also what a waste of die space.

don't blame the processor...blame the laggy resource hog OS!

I see. Maybe you need a wang wacking in your face to wake up, my friend. :)

Cortex-A57 and specially A72 is anything but low performing. This chip is actually one of the most interesting I have seen from MT, considering they usually just use lower spec cores like A9 and A53. The GPU might even blow away the Mali T760 MP6 in Exynos 7420.

The 7420 has Mali T760 MP8, not MP6.

The GPU of this new Mediatek will never beat top GPUs because it is still four core and still has poor fillrate.

but ARM Cortex A72 is the highest performance core today :-/ A53 and A57 also high performance core, they used in snapdragon 810 and samsung S6's exynos

I'll hold my judgement until the real life test of this chip. Beside, as everyday phone driver, how much process power do you really need. If you really want to chase spec, go to the PC world. That's where the big boys are at. With phones, it's all pre-build anyway.

let them be no need to resist it, it's a step in smartphone evolve.

Pretty sure this Soc will have a better performanc to $ ratio than Quallcom and samsung offers.

lol ok MediaTek. Lets see how this turns out!
