New Features and Specifications
It is increasingly obvious that in the high end smartphone and tablet market, much like we saw occur over the last several years in the PC space, consumers are becoming more concerned with features and experiences than just raw specifications. There is still plenty to drool over when looking at and talking about 4K screens in the palm of your hand, octa-core processors and mobile SoC GPUs measuring performance in hundreds of GFLOPS, but at the end of the day the vast majority of consumers want something that does something to “wow” them.
As a result, device manufacturers and SoC vendors are shifting priorities for performance, features and how those are presented both the public and to the media. Take this week’s Qualcomm event in San Diego where a team of VPs, PR personnel and engineers walked me through the new Snapdragon 810 processor. Rather than showing slide after slide of comparative performance numbers to the competition, I was shown room after room of demos. Wi-Fi, LTE, 4K capture and playback, gaming capability, thermals, antennae modifications, etc. The goal is showcase the experience of the entire platform – something that Qualcomm has been providing for longer than just about anyone in this business, while educating consumers on the need for balance too.
As a 15-year veteran of the hardware space my first reaction here couldn’t have been scripted any more precisely: a company that doesn’t show performance numbers has something to hide. But I was given time with a reference platform featuring the Snapdragon 810 processor in a tablet form-factor and the results show impressive increases over the 801 and 805 processors from the previous family. Rumors of the chips heat issues seem overblown, but that part will be hard to prove for sure until we get retail hardware in our hands to confirm.
Today’s story will outline the primary feature changes of the Snapdragon 810 SoC, though there was so much detail presented at the event with such a short window of time for writing that I definitely won’t be able to get to it all. I will follow up the gory specification details with performance results compared to a wide array of other tablets and smartphones to provide some context to where 810 stands in the market.

This is just a quick note for a small subset of our audience. If any of our developer-minded readers are in the Phoenix, Arizona region on February 19th, Intel will be hosting a meetup at UAT (the University of Advancing Technology). The processor vendor will perform a technical presentation about the Edison Internet-of-Things (IoT) developer kit. Shortly after the presentation, the group will move to Aunt Chilada's for a social event.
The presentation will take place in the theatre (there is only one as far as I can tell) at 6:30pm. Admission is free and there will be 10 Intel Edison kits to be raffled. Food and beverages will be provided by Intel (at Aunt Chilada's restaurant).

Tagged: amd, amazon
So allegedly Amazon UK sold some AMD A8-7600 APUs, but they actually shipped Athlon 64 X2 5200+ CPUs. Despite what you would think, it was actually “dispatched and sold” by Amazon UK itself, rather than a dishonest seller who has some explaining to do. For those affected, Amazon is apparently handling customer service well, as expected, and promptly replacing the parts. It does not seem to affect other regions, and the problem started just a short time ago.
Unless you're Sebastian, these processors will not even fit in the motherboard socket. PC World has an interesting side-by-side comparison of the two pin configurations. They do not look alike at all. You should not have a hard time identifying the problem if you are careful enough to look before you insert, which is obviously something that you shouldn't have to do. Also, AMD refers customers to their authenticity support page for a few extra ways to be sure that the box that you got came from AMD.
What would be the most interesting part of this story is finding out what happened. Unfortunately, we probably will never know, unless it turns into a famous legal battle of some sort.
SFF PCs get an upgrade
Ultra compact computers, otherwise known as small form factor PCs, are a rapidly increasing market as consumers realize that, for nearly all purposes other than gaming and video editing, Ultrabook-class hardware is "fast enough". I know that some of our readers will debate that fact, and we welcome the discussion, but as CPU architectures continue to improve in both performance and efficiency, you will be able to combine higher performance into smaller spaces. The Gigabyte BRIX platform is the exact result that you expect to see with that combination.
Previously, we have seen several other Gigabyte BRIX devices including our first desktop interaction with Iris Pro graphics, the BRIX Pro. Unfortunately though, that unit was plagued by noise issues - the small fan spun pretty fast to cool a 65 watt processor. For a small computer that would likely sit on top of your desk, that's a significant drawback.
Intel Ivy Bridge NUC, Gigabyte BRIX S Broadwell, Gigabyte BRIX Pro Haswell
This time around, Gigabyte is using the new Broadwell-U architecture in the Core i7-5500U and its significantly lower, 15 watt TDP. That does come with some specification concessions though, including a dual-core CPU instead of a quad-core CPU and a peak Turbo clock rate that is 900 MHz lower. Comparing the Broadwell BRIX S to the more relevant previous generation based on Haswell, we get essentially the same clock speed, a similar TDP, but also an improved core architecture.
Today we are going to look at the new Gigabyte BRIX S featuring the Core i7-5500U and an NFC chip for some interesting interactions. The "S" designates that this model could support a full size 2.5-in hard drive in addition to the mSATA port.
ARM Releases Top Cortex Design to Partners
ARM has an interesting history of releasing products. The company was once in the shadowy background of the CPU world, but with the explosion of mobile devices and its relevance in that market, ARM has had to adjust how it approaches the public with their technologies. For years ARM has announced products and technology, only to see it ship one to two years down the line. It seems that with the increased competition in the marketplace from Apple, Intel, NVIDIA, and Qualcomm ARM is now pushing to license out its new IP in a way that will enable their partners to achieve a faster time to market.
The big news this time is the introduction of the Cortex A72. This is a brand new design that will be based on the ARMv8-A instruction set. This is a 64 bit capable processor that is also backwards compatible with 32 bit applications programmed for ARMv7 based processors. ARM does not go into great detail about the product other than it is significantly faster than the previous Cortex-A15 and Cortex-A57.
The previous Cortex-A15 processors were announced several years back and made their first introduction in late 2013/early 2014. These were still 32 bit processors and while they had good performance for the time, they did not stack up well against the latest A8 SOCs from Apple. The A53 and A57 designs were also announced around two years ago. These are the first 64 bit designs from ARM and were meant to compete with the latest custom designs from Apple and Qualcomm’s upcoming 64 bit part. We are only now just seeing these parts make it into production, and even Qualcomm has licensed the A53 and A57 designs to insure a faster time to market for this latest batch of next-generation mobile devices.
We can look back over the past five years and see that ARM is moving forward in announcing their parts and then having their partners ship them within a much shorter timespan than we were used to seeing. ARM is hoping to accelerate the introduction of its new parts within the next year.

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.

Tagged: rumor, processors, Kaveri, Godavari, cpu, Athlon X4, APU, amd
VR-Zone has published a report with a detailed slide showing upcoming AMD Godavari processors, and the updated lineup includes 12 new models.
The release schedule indicates a spring availability for most of the new APUs, with the Athlon X4 850 and 870K shipping in May. The APU line gets a new flagship desktop part with the A10-8850K, and this appears to be a higher-clocked version of the A10-7850K, with a 100MHz higher boost clock (4.1 GHz vs. 4.0 GHz) and a higher GPU clock of 856 MHz (vs. 720 MHz).
Of particular interest for the potential budget quad-core buyer is the Athlon X4 870K, a new 95W part which would presumably replace the X4 860K - a processor that has seen inconsistent availability (and is currently unavailable on Newegg). With more games being released that require a quad-core to run, these sub-$100 Athlon CPUs present a great value in constructing a low-cost gaming system these days.
The slide does not indicate a change in the 28nm process from Kaveri, and it should be safe to assume these will not represent a significant architectural change. The modest clock increases from Kaveri will result in some performance gains, and this is good for consumers assuming these will sell at the same price points as the outgoing models.

A new report of leaked benchmarks paints a very interesting picture of the upcoming AMD Carrizo mobile APU.
Image credit: SiSoftware
Announced as strictly mobile parts, Carrizo is based on the next generation Excavator core and features what AMD is calling one of their biggest ever jumps in efficiency. Now alleged leaked benchmarks are showing significant performance gains as well, with numbers that should elevate the IGP dominance of AMD's APUs.
Image credit: WCCFtech
"The A10 7850K scores around 270 Mpix/s while Intel’s HD5200 Iris Pro scores a more modest 200 Mpix/s. Carriso scores here over 600 Mpix/s which suggests that Carrizo is more than twice as fast as Kaveri and three times faster than Iris Pro. To put this into perspective this is what an R7 265 graphics card scores, a card that offers the same graphics performance inside the Playstation 4."
While the idea of desktop APUs with greatly improved graphics and higher efficency is tantalizing, AMD has made it clear that these will be mobile-only parts at launch. When asked by Anandtech, AMD had this to say about the possibility of a desktop variant:
“With regards to your specific question, we expect Carrizo will be seen in BGA form factor desktops designs from our OEM partners. The Carrizo project was focused on thermally constrained form factors, which is where you'll see the big differences in performance and other experiences that consumers value.”
The new mobile APU will be manufactured with the same 28nm process as Kaveri, with power consumption up to 35W for the Carrizo down to a maximum of 15W for the ultra-mobile Carrizo-L parts.

Tagged: Pentium G3258, overclock, Intel
You just don't see CPU overclocking guides much anymore, the process has become much easier over the years as Intel and AMD both now sell unlocked CPUs that they expect you to overclock and the motherboard tools and UEFI interfaces do a lot of the heavy lifting for you now. No longer are you doing calculations for frequency ratios or drawing on your CPU with conductive ink. Overclockers Club is revisiting those heydays with a guide on how to make your $70 3.2GHz Pentium G3258 into a more serious beast with a speed well over 4GHz. The steps for overclocking are not difficult but for those who do not have a background in overclocking CPUs, the verification testing steps they describe will be of great value. If you are already well versed in the ways of MemTest86 and Prime95 then perhaps it will be a nice reminder of the days of the Celeron and the huge increases in frequency that family rewarded the patient overclocker with.
"To reach 4.7GHz was a cinch once I adjusted all the smaller voltage settings. Like all overclockers, it was a journey with many failures along the way. One day it would boot and run Prime95, and the next time Windows would not load. It took a while to sort it out by backing down to 4.5GHz and raising each setting until I settled on the below settings."

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.
