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).
Qualcomm Goes Ultrasonic
Qualcomm has unveiled what it claims is the world’s first ‘ultrasonic’ fingerprint scanner, in a bid to improve mobile security and further boost Android’s chances in the enterprise space.
The Qualcomm Snapdragon Sense ID 3D Fingerprint technology debuted during the chipmaker’s Mobile World Congress (MWC) press conference on Monday.
The firm claimed that the new feature will outperform the fingerprint scanners found on smartphones such as the iPhone 6 and Galaxy S6.
Qualcomm also claimed that, as well as “better protecting user data”, the 3D ultrasonic imaging technology is much more accurate than capacitive solutions currently available, and is not hindered by greasy or sweaty fingers.
Sense ID offers a more “innovative and elegant” design for manufacturers, the firm said, owing to its ability to scan fingerprints through any material, be it glass, metal or sapphire.
This means, in theory, that future fingerprint sensors could be included directly into a smartphone’s display.
Derek Aberle, Qualcomm president, said: “This is another industry first for Qualcomm and has the potential to revolutionise mobile security.
“It’s also another step towards the end of the password, and could mean that you’ll never have to type in a password on your smartphone again.”
No specific details or partners have yet been announced, but Qualcomm said that the Sense ID technology will arrive in devices in the second half of 2015, when the firm’s next-generation Snapdragon 820 processor is also tipped to debut.
The firm didn’t reveal many details about this chip, except that it will feature Kryo 64-bit CPU tech and a new machine learning feature dubbed Zeroth.
Qualcomm also revealed more details about LTE-U during Monday’s press conference, confirming plans to extend LTE to unused spectrum using technology integrated in its latest small-cell solutions and RF transceivers for mobile devices.
“We face many challenges as demand for data constantly grows, and we think the best way to fix this is by taking advantage of unused spectrum,” said Aberle.
Finally, the chipmaker released details about a new a partnership with Cyanogen, the open-source outfit responsible for the CyanogenMod operating system.
Qualcomm said that it will provide support for the best features and UI enhancements of CyanogenMod on Snapdragon processors, which will be available for the release of Qualcomm Reference Design in April.
The MWC announcements follow the launch of the ARM Cortex-based Snapdragon 620 and 618 chips last month, which promise to improve connectivity and user experience on high-end smartphones and tablets.
Aberle said that these chips will begin to show up in devices in mid to late 2015.
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
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.
Will The Chip Industry Take Fall?
Microchip Technology has managed to scare Wall Street by warning of an industry downturn. This follows rumours that a number of US semiconductor makers with global operations are reducing demand for chips in regions ranging from Asia to Europe.
Microchip Chief Executive Steve Sanghi warned that the correction will spread more broadly across the industry in the near future. Microchip expects to report sales of $546.2 million for its fiscal second quarter ending in September. The company had earlier forecast revenue in a range of $560 million to $575.9 million. Semiconductor companies’ shares are volatile at the best of times and news like this is the sort of thing that investors do not want to hear.
Trading in Intel, whiich is due to report third quarter results tomorrow, was 2.6 times the usual volume. Micron, which makes dynamic random access memory, or DRAM, was the third-most traded name in the options market. All this seems to suggest that the market is a bit spooked and much will depend on what Chipzilla tells the world tomorrow as to whether it goes into a nosedive.
MediaTek Goes IoT
SoC designer MediaTek has launched a new push to develop technologies used in wearables and Internet-of-Things (IoT) devices.
Dubbed MediaTek Labs, the new organisation will offer tools for developers such as software and hardware development kits (SDKs and HDKs), but it will also offer other forms of support, i.e. tech support and marketing.
MediaTek LinkIt dev platform
The MediaTek LinkIt platform promises to offer a full-service approach for developers keen to enter the space. It allows developers familiar with MediaTek’s Arduino implementation to quickly migrate to the new platform
For the time being the platform is limited to the MediaTek Aster MT2502A processor. The company says it is the world’s smallest commercially available SoC. The chip can work with MediaTek’s WiFi and GPS companion chipsets.
The company is calling on developers to join the MediaTek Labs initiative and in case you are interested you can check out the details on the new MediaTek Labs website.
MediaTek Aster spec
Now for some juicy hardware. The Aster MT2502A is an ARM7 EJ-S part clocked at 260MHz. The dev board features 4MB of RAM and 16MB of flash. GPS and WiFi capability can be added using the MT3332 and MT5931 chips. The platform supports microSD, Bluetooth (including BLE), along with GSM and GPRS communications.
The Aster is clearly not an SoC for feature packed wearables with high resolution screens, but it could be used in more down to earth applications such as fitness trackers.
MediaTek says it will offer three platforms based on two wearable solutions. The One Application Use (OAU) platform is for fitness trackers and simple Bluetooth devices. The Simple Application Platform (SAU) is intended for smart watches, wristbands and more elaborate fitness trackers.
SAU is the focus segment for the Aster chipset and it should offer 5 to 7 days of battery life.
MediaTek Rich Application Platform
The Rich Application Platform (RAU) is for Android Wear and it will offer a lot more functionality out of the box, including camera support, 3D graphics, as well as Bluetooth, WiFi and GPS in the same package.
This platform sounds a bit more interesting, but details are sketchy. For some reason many media outlets erroneously described the first Aster chip as MediaTek’s only smartwatch chip, but it is clearly not intended for the Rich Application Platform.
We have yet to see what sort of silicon MediaTek can conjure up for high-end wearables, but this is what it has in mind. The platform is designed for high-end smartwatches and glasses. It will feature multicore processors clocked at 1GHz or more. The platform also includes Bluetooth, GSM/GPRS, GPS, WiFi, sensors and a proper TFT screen. Battery life is described as short, two to three days, which sounds a bit better than what the current generation of smartwatches can deliver.
ARM Launches Juno
ARM has announced two programs to assist Android’s ascent into the 64-bit architecture market.
The first of those is Linaro, a port of the Android Open Source Project to the 64-bit ARMv8-A architecture. ARM said the port was done on a development board codenamed “Juno”, which is the second initiative to help Android reach the 64-bit market.
The Juno hardware development platform includes a system on chip (SoC) powered by a quad-core ARM Cortex-A53 CPU and dual-core ARM Cortex-A57 CPU in an ARM big.little processing configuration.
Juno is said to be an “open, vendor neutral ARMv8 development platform” that will also feature an ARM Mali-T624 graphics processor.
Alongside the news of the 64-bit initiatives, ARM also announced that Actions Semiconductor of China signed a license agreement for the 64-bit ARM Cortex-A50 processor family.
“Actions provides SoC solutions for portable consumer electronics,” ARM said. “With this IP license, Actions will develop 64-bit SoC solutions targeting the tablet and over-the-counter (OTT) set top box markets.”
The announcements from ARM come at an appropriate time, as it was only last week that Google announced the latest version of its Android mobile operating system, Android L, which comes with support for 64-bit processors. ARM’s latest developments mean that Android developers are likely to take advantage of them in the push to take Android to the 64-bit market.
Despite speculation that it would launch as Android 5.0 Lollipop, Google outed its next software iteration on Wednesday last week as simply Android L, touting the oddly-named iteration as “the largest update to the operating system yet”.
Can MediTek Win With Amazon?
According to the Taiwan Economic Daily, the chipmaker will supply SoCs for upcoming Amazon tablets. Details are sketchy and it is unclear whether MediaTek has landed an order for all Kindle Fire SKUs or just one of them. The paper claims MediaTek will start shipping the chips later this year, but we have no way of confirming or denying the report.
The chip in question appears to be the MT8135. It is a mid-range big.LITTLE part announced last year and it features two Cortex A15 and two Cortex A7 CPU cores. The GPU comes from Imagination and it’s the relatively fresh PowerVR G6200. The GPU is capable of churning out 83.2 GFLOPS at 650MHz, depending on the configuration of course.
It sounds like a decent all-round SoC, with a substantially faster GPU than previous MediaTek offerings in the same segment, which were powered by venerable SGX 54x and Mali 400/450 GPUs.
Information is limited and we can’t say for sure whether or not MediaTek actually landed the deal, or whether the deal includes more than a single Kindle Fire SKU. If true, it is a big coup for the Taiwan-based chipmaker, as Amazon ships up to two million Kindle tablets each quarter.
It would also help MediaTek’s ambitious tablet plans. The company hopes to double shipments of tablet-centric SoC products this year.
ARM To Focus On 64-bit SoC
ARM announced its first 64-bit cores a while ago and SoC makers have already rolled out several 64-bit designs. However, apart from Apple nobody has consumer oriented 64-bit ARM devices on the market just yet. They are slowly starting to show up and ARM says the transition to 64-bit parts is accelerating. However, the first wave of 64-bit ARM parts is not going after the high-end market.
Is 64-bit support on entry-level SoCs just a gimmick?
This trend raises a rather obvious question – are low end ARMv8 parts just a marketing gimmick, or do they really offer a significant performance gain? There is no straight answer at this point. It will depend on Google and chipmakers themselves, as well as phonemakers.
Qualcomm announced its first 64-bit part late last year. The Snapdragon 410 won’t turn many heads. It is going after $150 phones and it is based on Cortex A53 cores. It also has LTE, which makes it rather interesting.
MediaTek is taking a similar approach. Its quad-core MT6732 and octa-core MT6752 parts are Cortex A53 designs, too. Both sport LTE connectivity.
Qualcomm and MediaTek appear to be going after the same market – $100 to $150 phones with LTE and quad-core 64-bit stickers on the box. Marketers should like the idea, as they’re getting a few good buzzwords for entry-level gear.
However, we still don’t know much about their real-world performance. Don’t expect anything spectacular. The Cortex A53 is basically the 64-bit successor to the frugal Cortex A7. The A53 has a bit more cache, 40-bit physical addresses and it ends up a bit faster than the A7, but not by much. ARM says the A7 delivers 1.9DMIPS/MHz per core, while the A53 churns out 2.3DMIPS/MHz. That puts it in the ballpark of the good old Cortex A9. The first consumer oriented quad-core Cortex A9 part was Nvidia’s Tegra 3, so in theory a Cortex A53 quad-core could be as fast as a Tegra 3 clock-for-clock, but at 28nm we should see somewhat higher clocks, along with better graphics.
That’s not bad for $100 to $150 devices. LTE support is just the icing on the cake. Keep in mind that the Cortex A7 is ARM’s most efficient 32-bit core, hence we expect nothing less from the Cortex A53.
The Cortex A57 conundrum
Speaking to CNET’s Brooke Crothers, ARM executive vice president of corporate strategy Tom Lantzsch said the company was surprised by strong demand for 64-bit designs.
“Certainly, we’ve had big uptick in demand for mobile 64-bit products. We’ve seen this with our [Cortex] A53, a high-performance 64-bit mobile processor,” Lantzch told CNET.
He said ARM has been surprised by the pace of 64-bit adoption, with mobile parts coming from Qualcomm, MediaTek and Marvell. He said he hopes to see 64-bit phones by Christmas, although we suspect the first entry-level products will appear much sooner.
Lantzsch points out that even 32-bit code will run more efficiently on 64-bit ARMv8 parts. As software support improves, the performance gains will become more evident.
But where does this leave the Cortex A57? It is supposed to replace the Cortex A15, which had a few teething problems. Like the A15 it is a relatively big core. The A15 was simply too big and impractical on the 32nm node. On 28nm it’s better, but not perfect. It is still a huge core and its market success has been limited.
As a result, it’s highly unlikely that we will see any 28nm Cortex A57 parts. Qualcomm’s upcoming Snapdragon 810 is the first consumer oriented A57 SoC. It is a 20nm design and it is coming later this year, just in time for Christmas as ARM puts it. However, although the Snapdragon 810 will be ready by the end of the year, the first phones based on the new chip are expected to ship in early 2015.
While we will be able to buy 64-bit Android (and possibly Windows Phone) devices before Christmas, most if not all of them will be based on the A53. That’s not necessarily a bad thing. Consumers won’t have to spend $500 to get a 64-bit ARM device, so the user base could start growing long before high-end parts start shipping, thus forcing developers and Google to speed up 64-bit development.
If rumors are to be believed, Google is doing just that and it is not shying away from small 64-bit cores. The search giant is reportedly developing a $100 Nexus phone for emerging markets. It is said to be based on MediaTek’s MT6732 clocked at 1.5GHz. Sounds interesting, provided the rumour turns out to be true.
nVidia Speaks On Performance Issue
Nvidia has said that most of the outlandish performance increase figures touted by GPGPU vendors was down to poor original code rather than sheer brute force computing power provided by GPUs.
Both AMD and Nvidia have been using real-world code examples and projects to promote the performance of their respective GPGPU accelerators for years, but now it seems some of the eye popping figures including speed ups of 100x or 200x were not down to just the computing power of GPGPUs. Sumit Gupta, GM of Nvidia’s Tesla business said that such figures were generally down to starting with unoptimized CPU code.
During Intel’s Xeon Phi pre-launch press conference call, the firm cast doubt on some of the orders of magnitude speed up claims that had been bandied about for years. Now Gupta told The INQUIRER that while those large speed ups did happen, it was possible because of poorly optimized code to begin with, thus the bar was set very low.
Gupta said, “Most of the time when you saw the 100x, 200x and larger numbers those came from universities. Nvidia may have taken university work and shown it and it has an 100x on it, but really most of those gains came from academic work. Typically we find when you investigate why someone got 100x [speed up] is because they didn’t have good CPU code to begin with. When you investigate why they didn’t have good CPU code you find that typically they are domain scientist’s not computer science guys – biologists, chemists, physics – and they wrote some C code and it wasn’t good on the CPU. It turns out most of those people find it easier to code in CUDA C or CUDA Fortran than they do to use MPI or Pthreads to go to multi-core CPUs, so CUDA programming for a GPU is easier than multi-core CPU programming.”
