Tagged: mt6753, mediatek
We do not talk about MediaTek's higher-end products too often. Part of that is because they use stock architectures, ARM's Cortex CPU, ARM's Mali GPU, and Imagination Technologies' PowerVR GPU, rather than designing their own CPU and/or GPU portion. Likewise, their design wins are also not covered too much on this site, such as the new Amazon Fire HD tablets, for their own reasons. They still make some interesting chips, though.

The MediaTek MT6753 is a true eight-core, 64-bit ARM SoC. Its press release makes the rest of its details... confusing. The release claims that it is clocked at 1.5 GHz and contains an ARM Mali-T720 GPU that is capable of OpenGL ES 3.0 and OpenCL 1.2. The ARM Mali-T720 is actually capable of OpenGL ES 3.1 and OpenCL 1.1. This leads some sites to report that the MT6753 actually contains a Mali-T760, which is newer and can utilize OpenGL ES 3.1 and OpenCL 1.2 (it is also used in the MT6752 that was released several months ago). Other sites report what MediaTek claims.
GSM-Arena, one site that claims the (more-sensible) Mali-T760, also claims that the Cortex CPU cores can be clocked up to 1.7 GHz. This might not be inaccurate either, because it could be intended to run at ~1.3 to 1.5 GHz with a 1.7 GHz peak for vendors that want to take it to eleven. Alternatively, they could be wrong and it could peak at 1.5 GHz. We don't know, and MediaTek should be more clear about these important details.
Everyone seems to agree on the chip's networking capability, though. It will directly support LTE protocols for both China and western markets. This is expected to make them more competitive against Qualcomm, which might lead to more interesting designs.
Devices containing the MT6753 are expected to ship next quarter.

When you start getting into the wearables market, even mobile SoCs can be somewhat big and power-hungry. As such, we are seeing more innovation in processors that satisfy these lower classes (which could just be us paying more attention). The MediaTek MT2601 is one such device, which combines a pair of ARM Cortex-A7 cores (1.2 GHz) with an ARM Mali 400MP GPU (intended frequency unknown) on a
package PCB that is less than 480mm2. (Edit @ 9:48PM -- they seem to mean the SoC and other chips, like the Bluetooth module)
Of course, these chips are designed to be low cost, low power, and whatever performance can be squeezed out of those two requirements, so it might not be the most interesting SoC that we can talk about. Still, battery life has been a major hindrance to smart watches and other small, niche devices. It will be interesting to see new-generation devices that use these components.
Heck, if I had more time, I might even want to hack around with these directly.

Today, Lenovo announced a refreshed lineup of its A-series tablets including the A7-50, A8, and A10. The new tablets take a common hardware platform and scale it from a 7-inch tablet to a 10-inch tablet with optional keyboard. All three tablets run the Android 4.2 operating system and will be available in May.
The Lenovo TAB A7-50 Android 4.2 tablet.
The new Lenovo TAB A-series is powered by a quad core MediaTek 8121 SoC clocked at 1.3 GHz paired with 1GB of LP-DDR2 memory and 16GB of internal flash storage. Users can add an additional 32GB of storage with a micro SD card. Networking is handled by an 802.11 b/g/n Wi-Fi and Bluetooth 4.0 radio along with an optional SIM card slot on certain models (cellular functionality not available in the North American market). The tablets come with IPS touchscreens with a resolution of 1280 x 800. Lenovo includes a 2MP webcam and a 5MP rear facing camera on all three A-series tablets. The A10 further adds stereo speakers and compatibility with a keyboard dock.
Lenovo rates all three tablets at eight hours of battery life.
The Lenovo TAB A8 tablet.
Beyond the Lenovo TAB A10 being available with a Bluetooth keyboard dock, the only major differences between the new three A-series tablets are physical dimensions, screen size, and weight. The Lenovo TAB A7-50 measures 198x121.2x9.9mm and weighs 0.70 lbs. The TAB A8 meanwhile measures 217x136x8.9mm and weighs slightly more at 0.79 lbs. Finally, the TAB A10 measures 264x176.5x8.9mm and weighs 1.2 lbs.

The 7-inch Lenovo Tab A7-50 has an MSRP of $129 while the 8-Inch Tab A8 has an MSRP of $179. The 10.1-inch Tab A10 has a base price of $249 and is also available as a tablet and keyboard bundle for $299.
What do you think about Lenovo's new A-series lineup? On one hand, you have three size options at competitive prices, but on the other you only have a single option as far as internal specifications and screen resolution no matter the screen size. If you can live with the MTK 8121 and 1GB of RAM, they could be a viable option.

Tagged: mediatek, arm, cortex, A17
Our Josh Walrath wrote up an editorial about the Cortex-A17 architecture less than two days ago. In it, he reports on ARM's announcement that "the IP" will ship in 2015. On the same calendar date, MediaTek announced their MT6595 SoC, integrating A17 and A7 cores, will be commercially available in 1H 2014 with devices in 2H 2014.
Of course, it is difficult to tell how ahead of schedule this is, depending on what ARM meant by shipping in 2015 and what MediaTek meant by devices based on the MT6595 platform in 2H 2014.
There are two key features about the A17: a 40% power reduction from A15 and its ability to integrate with A7 cores in a big.LITTLE structure. MediaTek goes a little further with "CorePilot", which schedules tasks across all eight cores (despite it being a grouping of two different architectures). This makes some amount of sense because it allows for four strong threads which can be augmented with four weaker threads. Especially for applications like web browsers, it is not uncommon to have a dominant main thread.
The SoC will also support LTE and HSPA+ mobile and 802.11ac wireless connections. It will not integrate the Mali-T720 GPU (DX11/OpenGL ES 3.0), but instead use the Power VR Series6 GPU (DX10/OpenGL ES 3.0 unless it is an unannounced design). MediaTek does not explain why they chose the one licensed GPU over the other.
MediaTek claims the MT6595 platform will be available in the first half of 2014 with devices coming in the second half.

Tagged: CES, CES 2014, arm, Huawei, mediatek, 8 core
While clearly the need for an 8-core smartphone is still a debate, the enablement of hardware partners like Huawei, Mediatek and ARM are creating an ecosystem that enables the software developer to stretch their legs and innovate. While wandering around CES we ran into the Huawei G750 smartphone, the first to be powered by a true 8-core (octa-core) processor.
This phone likely isn't going to find its way to the US market but the design was solid and the user interface, as you would expect, was snappy and smooth. This processor from Mediatek, the MT6592, has the ability to run all 8 Cortex-A7 cores at the same time when the needs arise. Rather than go with the big.LITTLE design route Mediatek instead include 8 of the "little" cores in this design.
Each core is capable of clocking in at 2.0 GHz (though this Huawei model seems to cap at 1.7 GHz) and MediaTek claims that this allows support for 4K high bit-rate H.264 video playback as well as H.265 and VP9 playback.
The concern of a "core race" in the mobile market is definitely real though you have to be impressed by the drive for hardware vendors to improve capabilities. Now we just need to be sure that the software ecosystem and the power management designs are keeping up.

ASUS has released its own spin on a budget tablet with the new MeMo Pad HD 7. An updated model of the original MeMo Pad, the new 7” tablet runs Android 4.2.1 with newer hardware.
On the outside, the MeMo Pad HD 7 features a 1280x800 IPS display, 1.2 MP webcam, and 5 MP rear camera with auto focus. The top of the tablet hosts a micro USB port, microphone, and headphone jack. The MeMo Pad HD 7 measures 7.7” x 4.7” x 0.43” and weighs 0.67 pounds (303 grams). The MeMo Pad HD 7 comes in blue, green, pink, and white.
The ASUS MeMo Pad HD 7 is powered by a quad core MediaTek MT8125 SoC clocked at 1.2GHz, 1GB of RAM, 16GB of internal storage, and a 15Whr battery. Wireless radios include 802.11b/g/n Wi-Fi, Bluetooth 4.0, and Miracast wireless display support. The device also has two built in stereo speakers with Sonic Master audio technology.
Best of all, the budget tablet is available now with a price of $149. As an even more affordable alternative to the new Nexus 7, the ASUS MeMo Pad HD 7 looks to be a decent device.

MediaTek, do you even lift?
According to a Taiwan Media Roundtable transcript, discovered by IT World, Qualcomm has no interest, at least at the moment, in developing an octo-core processor. MediaTek, their competitor, recently unveiled an eight core ARM System on a Chip (SoC) which can be fully utilized. Most other mobile SoCs with eight cores function as a fast quad-core and a slower, but more efficient, quad-core processor with the most appropriate chosen for the task.
Anand Chandrasekher of Qualcomm believes it is desperation.
So, I go back to what I said: it's not about cores. When you can't engineer a product that meets the consumers' expectations, maybe that’s when you resort to simply throwing cores together. That is the equivalent of throwing spaghetti against the wall and seeing what sticks. That's a dumb way to do it and I think our engineers aren't dumb.
The moderator, clearly amused by the reaction, requested a firm clarification that Qualcomm will not launch an octo-core product. A firm, but not clear, response was given, "We don't do dumb things". Of course they would not commit to swearing off eight cores for all eternity, at some point they may find core count to be their bottleneck, but that is not the case for the moment. They will also not discuss whether bumping the clock rate is the best option or whether they should focus on graphics performance. He is just assured that they are focused on the best experience for whatever scenario each product is designed to solve.
And he is assured that Intel, his former employer, still cannot catch them. As we have discussed in the past: Intel is a company that will spend tens of billions of dollars, year over year, to out-research you if they genuinely want to play in your market. Even with his experience at Intel, he continues to take them lightly.
We don't see any impact from any of Intel's claims on current or future products. I think the results from empirical testers on our products that are currently shipping in the marketplace is very clear, and across a range of reviewers from Anandtech to Engadget, Qualcomm Snapdragon devices are winning both on experience as well as battery life. What our competitors are claiming are empty promises and is not having an impact on us.
Qualcomm has a definite lead, at the moment, and may very well keep ahead through Bay Trail. AMD, too, kept a lead throughout the entire Athlon 64 generation and believed they could beat anything Intel could develop. They were complacent, much as Qualcomm sounds currently, and when Intel caught up AMD could not float above the sheer volume of money trying to drown them.
Then again, even if you are complacent, you may still be the best. Maybe Intel will never get a Conroe moment against ARM.

During Computex Acer announced its new Liquid S1 smartphone. In fact, the term smartphone may not be enough to do the nearly tablet-sized 5.7” Liquid S1 justice, and Acer has even dubbed it a “phablet”.
On the outside, the Acer Liquid S1 has a massive 5.7” touchscreen with 720p resoultion surrounded by an aluminum side grip and a front 24mm and 8MP rear camera. The smartphone/tablet/phablet (heh) weighs in at 195g.
The new mobile device is powered by a quad core MediaTek SoC clocked at 1.5GHz, 1GB RAM, 8GB storage, and a 2,400mAh battery that Acer claims will last “all day.” The Liquid S1 runs Android 4.2.2, and offers a stock experience apart from Acer's multitasking Float UI and Cloud Docs document software. Other features include DTS StudioSound audio, dual SIM card slots, and a microSD card support (maximum of 32GB).
Wireless connectivity options include Bluetooth, Wi-Fi, and 3G radios as well as wireless display and wireless printing technology.
The Liquid S1 smartphone will be available in either matte black or white across Asia and Europe for 329 Euros. It is set for release sometime in the third quarter of this year (Q3'13). US users wanting a large smartphone (or small tablet) will need to either import the Acer model or look elsewhere as the company has not yet expanded its mobile offerings to this side of the pond, excluding laptops of course.

Tagged: texas instruments, mediatek, imagination, hsa foundation, hsa, arm, amd, AFDS
Today is a big day for AMD as they, along with four other major players in the world of processors and SoCs, announced the formation of the HSA Foundation. The HSA Foundation is a non-profit consortium created to define and promote an open approach to heterogeneous computing. The primary goal is to make it easier for software developers to write and program for the parallel power of GPUs. This encompasses both integrated and discrete of which the HSA (heterogeneous systems architecture) Foundation wants to enable users to take full advantage of all the processing resources available to them.
On stage at the AMD Fusion Developer Summit in Bellevue, WA, AMD announced the formation of the consortium in partnership with ARM, Imagination Technologies, MediaTek, and Texas Instruments; some of the biggest names in computing.
The companies will work together to drive a single architecture specification and simplify the programming model to help software developers take greater advantage of the capabilities found in modern central processing units (CPUs) and graphics processing units (GPUs), and unlock the performance and power efficiency of the parallel computing engines found in heterogeneous processors.
There are a lot of implications in this simple statement and there are many questions that are left open ended to which we hope to get answered this week while at AFDS. The idea of a "single architecture specification" set a lot of things in motion and makes us question the direction of both AMD and the traditionally ARM-based companies of the HSA Foundation will be moving in. AMD has had the APU, and the eventual complete fusion of the CPU and GPU, on its roadmap for quite a few years and has publicly stated that in 2014 they will have their first fully HSA-capable part. We are still assuming that this is an x86 + Radeon based part, but that may or may not be the long term goal; ideas of ARM-based AMD processors with Radeon graphics technology AND of Radeon based ARM-processors built by other companies still swirl amongst the show. There are even rumors of Frankenstein-like combinations of x86 and ARM based products for niche applications.
Looks like there is room for a few more founding partners...
Obviously ARM and others have their own graphics IP (ARM has Mali, Imagination Technology has Power VR) and those GPUs can be used for parallel processing in much the same way that we think of GPU processing on discrete GPUs and APUs today. ARM processor designers are well aware of the power and efficiency benefits of utilizing all of the available transistors and processing power correctly and the emphasis on an HSA-style system design makes a lot of sense moving forward.
My main question for the HSA Foundation is its goals: obviously they want to promote the simplistic approach for programmers, but what does that actually translate to on the hardware side? It is possible that both x86 and ARM-based ISAs can continue to exist with libraries and compilers built to correctly handle applications for each architecture, but that would seem to me to be against the goals of such a partnership of technology leaders.
In a meeting with AMD personnel, the most powerful and inspiring idea from the HSA Foundation is summed up with this:
"This is bigger than AMD. This is bigger than the PC ecosystem."
The end game is to make sure that all software developers can EASILY take advantage of both traditional and parallel processing cores without ever having to know what is going on under the hood. AMD and the other HSA Foundation members continue to tell us that this optimization can be completely ISA-agnostic – though the technical blockages for that to take place are severe.
AMD will benefit from the success of the HSA Foundation by finally getting more partners involved in promoting the idea of heterogeneous computing, and powerful ones at that. ARM is the biggest player in the low power processor market responsible for the Cortex and Mali architectures found in the vast majority of mobile processors. As those partners trumpet the same cause as AMD, more software will be developed to take advantage of parallel computing and AMD believes their GPU architecture gives them a definite performance advantage once that takes hold.
What I find most interesting is the unknown – how will this affect the roadmaps for all the hardware companies involved? Are we going to see the AMD APU roadmap shift to an ARM-IP system? Will we see companies like Texas Instruments fully integrate the OMAP and Power VR cores into a single memory space (or ARM with Cortex and Mali)? Will we eventually see NVIDIA jump onboard and lend their weight towards true heterogenous computing?
We have much more the learn about the HSA Foundation and its direction for the industry but we can easily say that this is probably the most important processor company collaboration announcement in many years – and it does so without the 800 pound gorilla that is Intel in attendance. By going after the ARM-based markets where Intel is already struggling to compete in, AMD can hope to create a foothold with technological and partnership advantages and return to a seat of prominence. This harkens back to the late 1990s when AMD famously put together the "virtual gorilla" with many partners to take on Intel.
