Can MediaTek Bring The Cortex-A72 To Market?

Comments Off on Can MediaTek Bring The Cortex-A72 To Market?

MediaTek became the first chipmaker to publicly demo a SoC based on ARM’s latest Cortex-A72 CPU core, but the company’s upcoming chip still relies on the old 28nm manufacturing process.

We had a chance to see the upcoming MT8173 in action at the Mobile World Congress a couple of weeks ago.

The next step is to bring the new Cortex-A72 core to a new node and into mobiles. This is what MediaTek is planning to do by the end of the year.

Cortex-A72 smartphone parts coming in Q4

It should be noted that MediaTek’s 8000-series parts are designed for tablets, and the MT8173 is no exception. However, the new core will make its way to smartphone SoCs later this year, as part of the MT679x series.

According to Digitimes Research, MediaTek’s upcoming MT679x chips will utilize a combination of Cortex-A53 and Cortex-A57 cores. It is unclear whether MediaTek will use the planar 20nm node or 16nm FinFET for the new part.

By the looks of it, this chip will replace 32-bit MT6595, which is MediaTek’s most successful high performance part yet, with a few relatively big design wins, including Alcatel, Meizu, Lenovo and Zopo. The new chip will also supplement, and possibly replace the recently introduced MT6795, a 64-bit Cortex-A53/Cortex-A72 part used in the HTC Desire 826.

More questions than answers

Digitimes also claims the MT679x Cortex-A72 parts may be the first MediaTek products to benefit from AMD technology, but details are scarce. We can’t say whether or not the part will use AMD GPU technology, or some HSA voodoo magic. Earlier this month we learned that MediaTek is working with AMD and the latest report appears to confirm our scoop.

The other big question is the node. The chip should launch toward the end of the year, so we probably won’t see any devices prior to Q1 2016. While 28nm is still alive and kicking, by 2016 it will be off the table, at least in this market segment. Previous MediaTek roadmap leaks suggested that the company would transition to 20nm on select parts by the end of the year.

However, we are not entirely sure 20nm will cut it for high-end parts in 2016. Huawei has already moved to 16nm with its latest Kirin 930 SoC, Samsung stunned the world with the 14nm Exynos 7420, and Qualcomm’s upcoming Snapdragon 820 will be a FinFET part as well.

It is obvious that TSMC’s and Samsung’s 20nm nodes will not be used on most, if not all, high-end SoCs next year. With that in mind, it would be logical to expect MediaTek to use a FinFET node as well. On the other hand, depending on the cost, 20nm could still make sense for MediaTek – provided it ends up significantly cheaper than FinFET. While a 20nm chip wouldn’t deliver the same level of power efficiency and performance, with the right price it could find its way to more affordable mid-range devices, or flagships designed by smaller, value-oriented brands (especially those focusing on Chinese and Indian markets).

MediaTek Shows Off New IoT Platform

Comments Off on MediaTek Shows Off New IoT Platform

MediaTek had announced a new development platform, as part of its MediaTek Labs initiative.

The LinkIt Connect MT7681 platform is based on the MT7681 SoC, designed for simple and affordable WiFi-enabled Internet of Things (IoT) devices. The company also released a software development kit (SDK) and hardware development kit (HDK) for the new platform.

The HDK includes the LinkIt Connect 7681 development board, which features the MT7681 chipset, micro-USB port and pins for various I/O interfaces. The chipset can be used in WiFi station or access point modes.

In station mode, the chip connects to a wireless access point and communicates with web services or cloud servers, which means it could be used to control smart thermostats. However, in access point mode, the chipset can communicate with devices directly, for example to control smart plugs or light bulbs using a smartphone.

“The world is rapidly moving towards connecting every imaginable device in the home, yet developers often have to spend too much effort on making their products Wi-Fi enabled,” said Marc Naddell, VP, MediaTek Labs. “The MediaTek LinkIt Connect 7681 platform simplifies and accelerates this process so that developers can focus on making innovative home IoT products, whatever their skill level.”

MediaTek Labs was launched in September 2014 and its goal is to promote a range of innovative MediaTek platforms, namely frugal devices such as wearables, IoT and home automation hardware.

MediaTek Cuts Xiaomi

Comments Off on MediaTek Cuts Xiaomi

The dark satanic rumour mill manufactured a hell on earth rumour that MediaTek has stopped supplying chips to Xiaomi.

MediaTek is apparently cross that Xiaomi has been investing in SoC supplier Leadcore Technology. Xiaomi has reportedly reached a deal with Leadcore allowing the phone maker to get access to the chip designer’s technology patents. DigiTimes however suggests that MediaTek has been trying to expand its presence in the mid-range and high-end market segments, but finds Xiaomi’s pricing strategy is disrupting its plans.

MediaTek’s MT6589T, a quad-core 1.5GHz chip, was originally designed to target mid-range and high-end mobile devices. The solution was introduced in Xiaomi’s Redmi smartphone in August 2013. However, prices for the Redmi series have been cut to as low as $114.

Xiaomi is ranked as the third largest smartphone vendor worldwide in the third quarter of 2014. Xiaomi’s shipments for the quarter registered a 211.3 per cent on-year jump boosting its market share to 5.3 per cent from 2.1 per cent during the same period of 2013.
