It's probably not a surprise to most that Futuremark is working on a new version of 3DMark around the release of DirectX 12. What might be new for you is that this version will include an API overhead test, used to evaluate a hardware configuration's ability to affect performance in Mantle, DX11 and DX12 APIs.
While we don't have any results quite yet (those are pending and should be very soon), Intel was showing the feature test running at an event at GDC tonight. In what looks like a simple cityscape being rendered over and over, the goal is to see how many draw calls, or how fast the CPU can react to a game engine, the API and hardware can be.
The test was being showcased on an Intel-powered notebook using a 5th Generation Core processor, code named Broadwell. Obviously this points to the upcoming support for DX12 (though obviously not Mantle) that Intel's integrated GPUs will provide.
It should be very interesting to see how much of an advantage DX12 offers over DX11, even on Intel's wide ranges of consumer and enthusiast processors.
SoFIA, Cherry Trail Make Debuts
Mobile World Congress is traditionally dominated by Samsung, Qualcomm, HTC, and others yet Intel continues to make in-roads into the mobile market. Though the company has admittedly lost a lot of money during this growing process, Intel pushes forward with today's announcement of a trio of new processor lines that keep the Atom brand. The Atom x3, the Atom x5, and the Atom x7 will be the company's answer in 2015 for a wide range of products, starting at the sub-$75 phone market and stretching up to ~$400 tablets and all-in-ones.
There are some significant differences in these Atom processors, more than the naming scheme might indicate.
Intel Atom x3 SoFIA Processor
For years now we have questioned Intel's capability to develop a processor that could fit inside the thermal envelope that is required for a smartphone while also offering performance comparable to Qualcomm, MediaTek, and others. It seemed that the x86 architecture was a weight around Intel's ankles rather than a float lifting it up. Intel's answer was the development of SoFIA, (S)mart (o)r (F)eature phone with (I)ntel (A)rchitecture. The project started about 2 years ago leading to product announcements finally reaching us today. SoFIA parts are "designed for budget smartphones; SoFIA is set to give Qualcomm and MediaTek a run for their money in this rapidly growing part of the market."
The SoFIA processors are based on the same Silvermont architecture as the current generation of Atom processors, but they are more tuned for power efficiency. Originally planned to be a dual-core only option, Intel has actually built both dual-core and quad-core variants that will pair with varying modem options to create a combination that best fit target price points and markets. Intel has partnered with RockChip for these designs, even though the architecture is completely IA/x86 based. Production will be done on a 28nm process technology at an unnamed vendor, though you can expect that to mean TSMC. This allows RockChip access to the designs, to help accelerate development, and to release them into the key markets that Intel is targeting.

While it is utterly inconceivable that Josh might have missed something in his look at Carrizo, that hasn't stopped certain Canadians from talking about Gila County, Arizona. AMD's upcoming processor launch is a little more interesting than just another Phenom II launch, especially for those worried about power consumption. With Adaptive Voltage and Frequency Scaling the new Excavator based chips will run very well at the sub-15W per core pair range which is perfect for POS, airplane entertainment and even in casinos. The GPU portion speaks to those usage scenarios though you can't expect an R9 295 at that wattage. Check out Hardware Canucks' coverage right here.
"AMD has been working hard on their mobile Carrizo architecture and they're now releasing some details about these Excavator architecture-equipped next generation APUs."
Here are some more Processor articles from around the web:
- AMD's new Carrizo: The x86 notebook processor that thinks it's a GPU @ The Register
- AMD Carrizo APU Details Revealed @ TechARP
- AMD FX-8320E Performance On Linux @ Phoronix
- Intel Broadwell HD Graphics 5500: Windows 8.1 vs. Linux @ Phoronix
- Preliminary Tests Of Intel Sandy Bridge & Ivy Bridge vs. Broadwell @ Phoronix
AMD Details Carrizo Further
Some months back AMD introduced us to their “Carrizo” product. Details were slim, but we learned that this would be another 28 nm part that has improved power efficiency over its predecessor. It would be based on the new “Excavator” core that will be the final implementation of the Bulldozer architecture. The graphics will be based on the latest iteration of the GCN architecture as well. Carrizo would be a true SOC in that it integrates the southbridge controller. The final piece of information that we received was that it would be interchangeable with the Carrizo-L SOC, which is a extremely low power APU based on the Puma+ cores.
A few months later we were invited by AMD to their CES meeting rooms to see early Carrizo samples in action. These products were running a variety of applications very smoothly, but we were not informed of speeds and actual power draw. All that we knew is that Carrizo was working and able to run pretty significant workloads like high quality 4K video playback. Details were yet again very scarce other than the expected timeline of release, the TDP ratings of these future parts, and how it was going to be a significant jump in energy efficiency over the previous Kaveri based APUs.
AMD is presenting more information on Carrizo at the ISSCC 2015 conference. This information dives a little deeper into how AMD has made the APU smaller, more power efficient, and faster overall than the previous 15 watt to 35 watt APUs based on Kaveri. AMD claims that they have a product that will increase power efficiency in a way not ever seen before for the company. This is particularly important considering that Carrizo is still a 28 nm product.
Intel Pushes Broadwell to the Next Unit of Computing
Intel continues to invest a significant amount of money into this small form factor product dubbed the Next Unit of Computing, or NUC. When it was initially released in December of 2012, the NUC was built as an evolutionary step of the desktop PC, part of a move for Intel to find new and unique form factors that its processors can exist in. With a 4" x 4" motherboard design the NUC is certainly a differentiating design and several of Intel's partners have adopted it for products of their: Gigabyte's BRIX line being the most relevant.
But Intel's development team continues to push the NUC platform forward and today we are evaluating the most recent iteration. The Intel NUC5i5RYK is based on the latest 14nm Broadwell processor and offers improved CPU performance, a higher speed GPU and lower power consumption. All of this is packed into a smaller package than any previous NUC on the market and the result is both impressive and totally expected.
A Walk Around the NUC
To most poeple the latest Intel NUC will look very similar to the previous models based on Ivy Bridge and Haswell. You'd be right of course - the fundamental design is unchanged. But Intel continues to push forward in small ways, nipping and tucking away. But the NUC is still just a box. An incredibly small one with a lot of hardware crammed into it, but a box none the less.
While I can appreciate the details including the black and silver colors and rounded edges, I think that Intel needs to find a way to add some more excitement into the NUC product line going forward. Admittedly, it is hard to inovate in that directions with a focus on size and compression.
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.

Tagged: Intel, edison, meetup
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.
