MediaTek says the new Helio X20 deca-core chip is too clever to overheat

Processor manufacturer MediaTek’s new Helio X20 chip is getting plenty of attention ahead of its forthcoming debut, but not in the way the company would really want. Rumors spread the chip was prone to overheating, and some smartphone firms had dropped plans to use it, something MediaTek went on to deny.

Following the overheating rumors, MediaTek wrote on the Weibo social network that the Helio X20 is working perfectly, and it has some clever technology inside that stops overheating becoming an issue. Apparently, if the chip detects it’s getting too hot, it turns off two cores and drops down to eight. If this sounds like a workaround, MediaTek’s quick to clarifies this is a fail-safe system that’s unlikely to be used.

A few days earlier, several major smartphone manufacturers were rumored to have canceled plans for future devices powered by the MediaTek Helio X20 processor, due to concerns regarding the chip overheating. The word spread from the Weibo social network, and the companies named were HTC, Lenovo, and Xiaomi. If that sounds familiar, it’s eerily similar to the situation faced by Qualcomm and the ill-fated Snapdragon 810The apparent cancellation is due to manufacturers inability to optimize the chip to overcome excessive generation of heat.

MediaTek’s Helio X20 is shaping up to be a mobile processing powerhouse. The deca-core chip has already been announced, and can run at a speedy 2.5GHz while consuming 30-percent less power than the Helio X10, seen in phones including the HTC One X9 and the Xiaomi Redmi Note 2. The X20 cleverly uses a “three gear” tri-cluster set up, where only selected cores are active depending on the tasks running. This improves on the “two gear” system seen on octa-core chips.

HTC uses MediaTek chips in phones often destined for markets other than the U.S., where it competes with Xiaomi and Lenovo, among others. Rumors surrounding the HTC Perfume/M20 have mentioned there may be two versions, one with a Snapdragon chip, and the other a MediaTek chip. HTC will certainly be wary of any heat-related issues, having stuffed the revised Snapdragon 810 inside the One M9, only to find it still didn’t cure the problem entirely.

Any problems faced by the MediaTek Helio X20 are rumor for now. MediaTek says mass production is already underway, and the first devices are coming very soon. Zopo Mobile, a Chinese brand, has been teasing the arrival of its Speed 8 phone for a while, for example, and it may be announced at MWC at the end of February.

MediaTek goes for gamers with new Helio G90 series smartphone chips

Smartphones designed primarily to appeal to mobile gamers are a growing niche, but the models that are available at the moment mostly occupy the higher end, and therefore carry steep prices. Processor manufacturer MediaTek has gotten in on the action with the Helio G90 series, chips designed for top-quality gaming on the move, complete with a new range of engines to optimize the experience. The good news here is that MediaTek has always focused on delivering premium features and performance on devices that don’t have premium prices.

Let’s talk about the technology. There are two new G90 series chips, the Helio G90 and the Helio G90T, although the difference between them is not clear. We’ve reched out to MediaTek to provide clarity, and will update here when we hear back. However, we do know the G90 uses the 64-bit ARM Cortex A76 and Cortex A55 octa-core platform — that’s what Qualcomm uses in processors like the Snapdragon 675 and 855 — with the ARM Mali G76 graphics processor (GPU), complete with the capacity for 10GB of LPDDR4 RAM. The Helio G90 chip will also support single cameras up to 64 megapixels or a dual-lens camera with a 24-megapixel lens and a second 16-megapixel lens.

Midrange phones can’t do A.I., but MediaTek’s P90 chip aims to change that
mediatek helio p90 interview chip dark

The Helio P90 is the latest processor to be announced by Taiwanese manufacturer MediaTek, and it serves several distinct purposes. It will shun the need to buy expensive high-end devices to use the latest artificial intelligence features, and see MediaTek potentially succeed in its goal of delivering value-driven devices with the latest tech. Additionally, it sets the company up as a serious force in the race to power the next billion people waiting to buy their first smartphone.

You’d be forgiven for thinking the quest to connect “the next billion” people falls solely at Google’s feet, seeing as it has spent almost entire keynote presentations talking about it with Android. Not quite. While Google is indeed a very large cog in the machine, MediaTek believes its involvement is so crucial, the company’s Chief Financial Officer David Ku boldly stated that if you want to “gain the next billion, you have to work with MediaTek.”

MediaTek’s Helio P90 chip has more A.I. tech than the entire Terminator franchise

Smartphones injected with artificial intelligence often cost quite a lot of money, but what if you could access this technology for a lot less? Sounds tempting doesn’t it, and that’s what MediaTek is aiming for with its next mobile processor, the Helio P90, which it will officially announce on December 13.

If you’re reading this and thinking you’ve seen such a claim before, it’s because MediaTek has a similar plan for the Helio P70 chip, which it revealed at the end of October. The Helio P90 goes several stages further than the P70, with MediaTek claiming the chip’s A.I. abilities have taken a three-fold leap over those offered by the P60 and P70. It will achieve this by using two application processing units (APU), and a new A.I. Accelerator (AIA).
