One Small Step
While most articles surrounding the iPhone 6 and iPhone 6 Plus this far have focused around user experience and larger screen sizes, performance, and in particular the effect of Apple's transition to the 20nm process node for the A8 SoC have been our main questions regarding these new phones. Naturally, I decided to put my personal iPhone 6 though our usual round of benchmarks.
First, let's start with 3DMark.
Comparing the 3DMark scores of the new Apple A8 to even the last generation A7 provides a smaller improvement than we are used to seeing generation-to-generation with Apple's custom ARM implementations. When you compare the A8 to something like the NVIDIA Tegra K1, which utilizes desktop-class GPU cores, the overall score blows Apple out of the water. Even taking a look at the CPU-bound physics score, the K1 is still a winner.
A 78% performance advantage in overall score when compared the A8 shows just how much of a powerhouse NVIDIA has with the K1. (Though clearly power envelopes are another matter entirely.)
If we look at more CPU benchmarks, like the browser-based Google Octane and SunSpider tests, the A8 starts to shine more.
While the A8 edges out the A7 to be the best performing device and 54% faster than the K1 in SunSpider, the A8 and K1 are neck and neck in the Google Octane benchmark.
Moving back to a graphics heavy benchmark, GFXBench's Manhattan test, the Tegra K1 has a 75% percent performance advantage over the A8 though it is 36% faster than the previous A7 silicon.
These early results are certainly a disappointment compared to the usual generation-to-generation performance increase we see with Apple SoCs.
However, the other aspect to look at is power efficiency. With normal use I have noticed a substantial increase in battery life of my iPhone 6 over the last generation iPhone 5S. While this may be due to a small (about 1 wH) increase in battery capacity, I think more can be credited to this being an overall more efficient device. Certain choices like sticking to a highly optimized Dual Core CPU design and Quad Core GPU, as well as a reduction in process node to 20nm all contribute to increased battery life, while surpassing the performance of the last generation Apple A7.
In that way, the A8 moves the bar forward for Apple and is a solid first attempt at using the 20nm silicon technology at TSMC. There is a strong potential that further refined parts (like the expected A8x for the iPad revisions) Apple will be able to further surpass 28nm silicon in performance and efficiency.

First, Chipworks released a dieshot of the new Apple A8 SoC (stored at archive.org). It is based on the 20nm fabrication process from TSMC, which they allegedly bought the entire capacity for. From there, a bit of a debate arose regarding what each group of transistors represented. All sources claim that it is based around a dual-core CPU, but the GPU is a bit polarizing.

Most sources, including Chipworks, Ars Technica, Anandtech, and so forth believe that it is a quad-core graphics processor from Imagination Technologies. Specifically, they expect that it is the GX6450 from the PowerVR Series 6XT. This is a narrow upgrade over the G6430 found in the Apple A7 processor, which is in line with the initial benchmarks that we saw (and not in line with the 50% GPU performance increase that Apple claims). For programmability, the GX6450 is equivalent to a DirectX 10-level feature set, unless it was extended by Apple, which I doubt.

DailyTech has their own theory, suggesting that it is a GX6650 that is horizontally-aligned. From my observation, their "Cluster 2" and "Cluster 5" do not look identical at all to the other four, so I doubt their claims. I expect that they heard Apple's 50% claims, expected six GPU cores as the rumors originally indicated, and saw cores that were not there.
Which brings us back to the question of, "So what is the 50% increase in performance that Apple claims?" Unless they had a significant increase in clock rate, I still wonder if Apple is claiming that their increase in graphics performance will come from the Metal API even though it is not exclusive to new hardware.
But from everything we saw so far, it is just a handful of percent better.

Tagged: Intel, spreadtrum, rda, Rockchip, SoC
A few months ago, Intel partnered with Rockchip to develop low-cost SoCs for Android. The companies would work together on a design that could be fabricated at TSMC. This time Intel is partnering with Tsinghua Unigroup Ltd. and, unlike Rockchip, also investing in them. The deal will be up to $1.5 billion USD in exchange for a 20% share (approximately) of a division of Tsinghua.

Intel is hoping to use this partnership to develop mobile SoCs, for smart (and "feature") phones, tablets, and other devices, and get significant presence in the Chinese mobile market. Tsinghua acquired Spreadtrum Communications and RDA Microelectronics within the last two years. The "holding group" that owns these division is apparently the part of Tsinghua which Intel is investing in, specifically.
Spreadtrum will produce SoCs based on Intel's "Intel Architecture". This sounds like they are referring to the 32-bit IA-32, which means that Spreadtrum would be developing 32-bit SoCs, but it is possible that they could be talking about Intel 64. These products are expected for 2H'15.

The Nexus line is due for an update, with each product being released for at least a year. They are devices which embody Google's vision... for their own platform. You can fall on either side of that debate, whether it guides OEM partners or if it is simply a shard the fragmentation issue, if you even believe that fragmentation is bad, but they are easy to recommend and a good benchmark for Android.
We are expecting a few new entries in the coming months, one of which being the Nexus 9. Of note, it is expected to mark the return of HTC to the Nexus brand. They were the launch partner with the Nexus One and then promptly exited stage left as LG, Samsung, and ASUS performed the main acts.
We found this out because NVIDIA spilled the beans on their lawsuit filing against Qualcomm and Samsung. Apparently, "the HTC Nexus 9, expected in the third quarter of 2014, is also expected to use the Tegra K1". It has since been revised to remove the reference. While the K1 has a significant GPU to back it up, it will likely be driving a very high resolution display. The Nexus 6 is expected to launch at around the same time, along with Android 5.0 itself, and the 5.2-inch phone is rumored to have a 1440p display. It seems unlikely that a larger, tablet display will be lower resolution than the phone it launches alongside -- and there's not much room above it.
The Google Nexus 9 is expected for "Q3".

Tagged: Red Hat, microsoft, Feedhenry
Red Hat just acquired Feedhenry for around €63.5 million to enhance their ability to support mobile apps. Feedhenry designs mobile apps on both the client and server side which run on Android, iOS, Windows Phone, QNX and HTML5 as well as integration with apps from companies such as Salesforce, SAP and Oracle. This purchase could help Red Hat become an attractive alternative for companies wishing to serve apps across all platforms and increased usage of Openshift and Openstack. The Inquirer also posted news on a extension to the price discount on Microsoft's licensing for mobile developers. They are still offering lifetime accounts for Dev Center for $19.99 for individuals and $99.99 for businesses, which compares favourably to the one time Android fee of $25 and even better against Apple's $99 per year. If they could just get their phones to play nicely with O365 this could well increase their market share for mobile phones.
"RED HAT HAS ACQUIRED Feedhenry, a designer of mobile apps for the enterprise market. The company sees the acquisition as a key driver to offer cross-platform support for its existing software products, including Red Hat Enterprise Linux Openstack 7, which it released earlier this year."

In much the same way as FirefoxOS is targeting foreign markets with low-cost phones, with the Intex Cloud Fx as the extreme example, Google is pushing for the overseas markets with Android One. Based on Android 4.4 and updated as new versions launch, for up to two years at least, the devices will not be old and outdated.
In terms of hardware, the platform is said to feature front and rear cameras, a quad-core processor, a microSD card slot, and dual SIM slots. Google has several partners involved with the initiative: Acer, Airtel, Alcatel, ASUS, HTC, Intex, Karbonn, LAVA, Lenovo, MediaTek, Cromax, Panasonic, Qualcomm, Spice, and Xolo. Besides a baseline standard, and a bit of marketing, there does not seem to be much to the platform itself.
Of course, delivering a quality standard, at an affordable price, to places which normally cannot obtain smartphones at all is noteworthy.

The Inquirer had a chance for some hands on time with the new Acer Aspire Switch 12 convertible tablet and keyboard. It is powered by the new Core M 5Y10a at 1Ghz, which does not require a fan and has 4GB of RAM and runs Win8. The screen specifications were not listed but their eyeballs suggest the screen is a full 1080p which is a great improvement from the usual 1366x768 on these convertible devices. They were not overly impressed by the quality of the keyboard or the process to attach or remove it from the screen but the sacrifice in aesthetics does help to keep the device very light and thin when the keyboard dock is attached. You can see their preview here, hopefully a full review will appear soon.
"The Aspire Switch 12 is the successor to the Taiwanese firm's previous affordable multi-mode device, the Aspire Switch 10. It boasts a slimmer design thanks to Intel's new 14nm fanless processor, has a 12.5in display and features five alternative viewing modes."

Tagged: radio-on-a-chip, iot, internet of things
Tiny and passively-powered radios would make for some interesting applications. One major issue is that you cannot shrink an antenna down infinitely; its size is dependent upon the wavelength of EM radiation that it is trying to detect. Researchers at Stanford and Berkeley have announced "ant-sized" radio-on-a-chip devices, fabricated at 65nm, which are powered by the signal that they gather.
The catch is that, because their antenna is on the order of a few millimeters, it is tuned for ~60 GHz. There are reasons why you do not see too many devices operate at this frequency. First, processing that signal with transistors is basically a non-starter, so they apparently designed a standard integrated circuit for the task.
The other problem is that 60 GHz is an Extremely High Frequency (EHF) and, with its high frequency, is very difficult to transmit over long ranges. The 57-64 GHz region, in particular, is a range which oxygen resonates at. While it is possible to brute-force a powerful signal through a sensitive antenna, that defeats the above purpose. Of course, the researchers have been honest about this. Right in their IEEE abstract, they claim a current, measured range of 50cm. In their Stanford press release, they state that this is designed to be part of a network with units every meter (or so). Current bandwidth is a little over 12 megabit.
Simply put, this will not become your new WiFi hotspot. However, for small and connected devices that are in close proximity, this could provide an interesting communication method for when size, cost, and power efficiency trump speed and range.

Tagged: motorola, moto 360, smartwatch
When I covered the announcement of the Apple Watch, one of our readers pointed out that we had very little smart watch coverage. That is fair critique, and I can see how it appeared to give Apple an unfair slant. As far as I know, we will not be reviewing any smart watch, of any sort, for the foreseeable future (my phone still runs Froyo). Engadget and Ars Technica did, though.
Android Wear launched with three smart watches: the LG G Watch, the Samsung Gear Live, and (after a little delay) the Motorola Moto 360. The third one is a bit different from the other two in that it features a round screen. Both sites like the design but complain about its use of a TI OMAP3 SoC and its limited battery life. The OMAP3630 is manufactured at 45nm, which is a few process shrinks behind today's 28nm products and soon-to-be-released devices with 20nm and 14nm processors. With a 300mAh battery, a little less than a half or a third of a typical AAA battery, this leads to frequent charging. The question is whether this will be the same for all smart watches, and we don't know that yet. The Samsung and the LG smart watches, under Ars Technica's custom benchmark, vastly outperform it, though.
Engadget also complained about its price, at $250 and $299, which is actually $100 and $50 less than Apple's starting price. Ars Technica neither praised nor complained about the price.

If you were on a mission to make the cheapest possible mobile phone, you would probably not do much better than Intex Cloud Fx. Running Firefox OS, it will cost users about $35 to purchase it outright. Its goal is to bring the internet to places which would otherwise have nothing.
I believe the largest concession made by this phone is its RAM -- 128 MB. Yes, I had a computer with 32 MB of RAM and it browsed the internet just fine (on Netscape Navigator 2 through 4). I also had a computer before that (which was too slow to run Windows 3.1 but hey it had a turbo button). This is also the amount of RAM on the first and second generation iPod Touches. Nowadays, it is very little. Ars Technica allegedly made it crash by scrolling too fast and attempting to run benchmarks on it. This leads into its other, major compromise: its wireless connectivity. It does not support 3G. Edge is the best that you will get.
Other than those two points: it has a 1 GHz Spreadtrum SoC, 46MB of storage, a 2MP camera, and a 1250mAh battery. You do get WiFi, Bluetooth, and a microSD card slot. It also supports two SIM cards if necessary.
Again, at $35, this is not designed for America or Western Europe. This is for the areas of the world that will probably not experience the internet at all unless it is through a mobile phone. For people in India and Asia, it is about the lowest barrier to entry of the internet that is possible. You can also check out phones from other partners of Mozilla.
