As Sebastian discovered when he delved into the world of MU-MIMO routers, benchmarking the performance of wireless devices is not as easy as it sounds. TweakTown recently put together a basic overview of the performance of a variety of wireless routers and NICs to see if there was one that stood out above the competition. They used Netperf to test the cards latency and throughput on these routers, graphing them out for easy viewing. The results display the performance at a distance of 20' from the router on both 2.4 and 5GHz bandwidths, with some interesting results. Pop by for a look.
"I've been pondering an article like this for a while but the logistics of getting everything in-house and testing never really came together. After completing my last round of articles, I suddenly realized I had all of the wireless NICs in-house that come in modern motherboards and laptops, apart from the Killer 1535, which easily enough was sent over to be included after emailing Rivet Networks."

Canonical, the company behind the Ubuntu Linux operating system, is now offering up its first Ubuntu tablet with Spanish manufacturing partner BQ. The Aquaris M10 Ubuntu Edition is a 10-inch tablet powered by ARM and loaded with Ubuntu 15.04.
The tablet features an all black (or white) case with rounded edges and a matte back. Mobilegeeks managed to get hands on with the Android version of the Aquaris M10 which you can check out here. The internals are a bit different on the Ubuntu Edition, but the chassis and design remains the same. It measures 8.2mm thick and weighs in at 470 grams (1.03 pounds). The front is dominated by a 10.1” AHVA touchscreen display that comes in either 1280 x 800 or Full HD 1920 x 1080 resolution depending on the model. A capacitive home button sits below along with two 0.7W speakers while a 5MP webcam is positioned above the display. There is an 8MP rear camera, and the sides hold Micro HDMI, Micro USB, Micro SD, and 3.5mm audio ports.
The Aquaris M10 Ubuntu Edition is powered by a quad core MediaTek SoC with Mali-T720MP2 graphics, 2GB of RAM, and 16GB of eMMC storage (with approximately 10GB usable by end users) that can be expanded via Micro SD cards up to 64GB. The Full HD model uses the MediaTek MT8163A clocked at 1.5 GHz while the HD Aquaris M10 uses the slightly lower clocked MT8163B running at 1.3 GHz.
Wireless capabilities include 802.11n (dual band) Wi-Fi, Bluetooth 4.0, and GPS. It is powered by a 7,280 mAh Li-Po battery. BQ has pre-loaded the tablet with Ubuntu 15.04 which users will likely want to update once drivers are ready as it is End-of-Life.
The Aquaris M10 is available for pre-order now, with expected ship dates in early April. The HD Ubuntu Edition tablet is listed at €259.90 ($295) while the Full HD version will run you €299.90 ($340). Currently, the Full HD tablet comes in black and the HD tablet is all white. Both models come with a screen protector and case as a pre-order bonus.
It is interesting to see an official Ubuntu tablet, but I wonder if this is too little, too late for the open source OS. Canonical is positioning this as a daily driver that can be a tablet when you want to be mobile, a PC when propped up with a case and paired with wireless keyboard and mouse, and a media streamer when connecting it to the big screen with HDMI. I would expect performance to improve over time once the community gets a hold of it and starts tweaking it though the hardware is going to be a limiting factor. I want a Linux tablet to succeed, and hopefully this will open the door for higher end models. I don’t see myself jumping on this particular one though at this price.
Are you excited for the Ubuntu Edition M10?

MediaTek might not be well-known in the United States, but the company has been working to expand from China, where it had a 40% market share as of June 2015, into the global market. While 2015 saw the introduction of the 8-core Helio P10 and the 10-core helio X20 SoCs, the company continues to expand their lineup, today announcing the Helio P20 SoC.
There are a number of differences between the recent SoCs from MediaTek, beginning with the CPU core configuration. This new Helio P20 is a “True Octa-Core” design, but rather than a big.LITTLE configuration it’s using 8 identically-clocked ARM Cortex-A53 cores at 2.3 GHz. The previous Helio P10 used a similar CPU configuration, though clocks were limited to 2.0 GHz with that SoC. Conversely, the 10-core Helio X20 uses a tri-cluster configuration, with 2x ARM Cortex-A72 cores running at 2.5 GHz, along with a typical big.LITTLE arrangement (4x Cortex-A53 cores at 2.0 Ghz and 4x Cortex-A53 cores at 1.4 GHz).
Another change affecting MediaTek’s new SoC and he industry at large is the move to smaller process nodes. The Helio P10 was built on 28 nm HPM, and this new P20 moves to 16 nm FinFET. Just as with the Helio P10 and Helio X20 (a 20 nm part) this SoC is produced at TSMC using their 16FF+ (FinFET Plus) technology. This should provide up to “40% higher speed and 60% power saving” compared to the company’s previous 20 nm process found in the Helio X20, though of course real-world results will have to wait until handsets are available to test.
The Helio P20 also takes advantage of LPDDR4X, and is “the world’s first SoC to support low power double data rate random access memory” according to MediaTek. The company says this new memory provides “70 percent more bandwidth than the LPDDR3 and 50 percent power savings by lowering supply voltage to 0.6v”. Graphics are powered by ARM’s high-end Mali T880 GPU, clocked at an impressive 900 MHz. And all-important modem connectivity includes CAT6 LTE with 2x carrier aggregation for speeds of up to 300 Mbps down, 50 Mbps up. The Helio P20 also supports up to 4k/30 video decode with H.264/265 support, and the 12-bit dual camera ISP supports up to 24 MP sensors.
Specs from MediaTek:
- Process: 16nm
- Apps CPU: 8x Cortex-A53, up to 2.3GHz
- Memory: Up to 2 x LPDDR4X 1600MHz (up to 6GB) + 1x LPDDR3 933Mhz (up to 4GB) + eMMC 5.1
- Camera: Up to 24MP at 24FPS w/ZSD, 12bit Dual ISP, 3A HW engine, Bayer & Mono sensor support
- Video Decode: Up to 4Kx2K 30fps H.264/265
- Video Encode: Up to 4Kx2K 30fps H.264
- Graphics: Mali T-880 MP2 900MHz
- Display: FHD 1920x1080 60fps. 2x DSI for dual display
- Modem: LTE FDD TDD R.11 Cat.6 with 2x20 CA. C2K SRLTE. L+W DSDS support
- Connectivity: WiFiac/abgn (with MT6630). GPS/Glonass/Beidou/BT/FM.
- Audio: 110db SNR & -95db THD
It’s interesting to see SoC makers experiment with less complex CPU designs after a generation of multi-cluster (big.LITTLE) SoCs, as even the current flagship Qualcomm SoC, the Snapdragon 820, has reverted to a straight quad-core design. The P20 is expected to be in shipping devices by the second half of 2016, and we will see how this configuration performs once some devices using this new P20 SoC are in the wild.

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.
Image Credit: A Weibo user via GSM-Arena
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.
