Rumor: Apple to Use AMD SoC for Next-Gen iMac News about AMD has been largely depressing of late, with the introduction of the R9 Fury/Fury X and Nano graphics cards a bright spot in the otherwise tumultuous year that was recently capped by a $65 million APU write down. But one area where AMD has managed to earn a big win has been the console market, where their APUs power the latest machines from Microsoft and Sony. The combination of CPU and a powerful GPU on a single chip is ideal for those small form-factor designs, and likewise it would be ideal for a slim all-in-one PC. But an iMac?

A report from WCCFtech today points to the upcoming Zen architecture from AMD as a likely power source for a potential custom SoC:
"A Semi-custom SOC x86 for the iMac would have to include a high performance x86 component, namely Zen, in addition to a graphics engine to drive the visual experience of the device. Such a design would be very similar to the current semi-custom Playstation 4 and XBOX ONE Accelerated Processing Units, combining x86 CPU cores with a highly capable integrated graphics solution."
Those who don't follow Apple probably don't know the company switched over almost exclusively to AMD graphics a short time ago, with NVIDIA solutions phased out of all discrete GPU models. Whether politically motivated or simply the result of AMD providing what Apple wanted from a hardware/driver standpoint I can't say, but it's still a big win for AMD considering Apple's position as one of the largest computer manufacturers - even though its market share is very low in the highly fragmented PC market overall. And while Apple has exclusively used Intel processors in its systems since transitioning away from IBM's PowerPC beginning in 2006, the idea of an AMD custom APU makes a lot of sense for the company, especially for their size and heat constrained iMac designs.

Whether or not you'd ever consider buying an iMac - or any other computer from Apple, for that matter - it's still important for the PC industry as a whole that AMD continues to find success and provide competition for Intel. Consumers can only benefit from the potential for improved performance and reduced cost if competition heats up between Intel and AMD, something we really haven't seen on the CPU front in a few years now. With CEO Lisa Su stating that AMD "had secured two new semi-custom design wins" In their recent earnings call it could very well be that we will see Zen in future iMacs, or in other PC all-in-one solutions for that matter.
Regardless, it will be exciting to see some good competition from AMD, even if we will have to wait quite a while for it. Zen isn't ready yet and we have no indication that any such product would be introduced until later next year. It will be interesting to see what Intel might do to compete given their resources. 2016 could be interesting.

The upcoming Snapdragon 820 is shaping up to be a formidable SoC after the disappointing response to the previous flagship, the Snapdragon 810, which was in far fewer devices than expected for reasons still shrouded in mystery and speculation. One of the biggest aspects of the upcoming 820 is Qualcomm’s new X12 modem, which will provide the most advanced LTE connectivity seen to date when the SoC launches. The X12 features CAT 12 LTE downlink speeds for up to 600 Mbps, and CAT 13 on the uplink for up to 150 Mbps.
LTE connectivity isn’t the only new thing here, as we see from this slide there is also tri-band Wi-Fi supporting 2x2 MU-MIMO.
“This is the first publicly announced processor for use in mobile devices to support LTE Category 12 in the downlink and Category 13 in the uplink, providing up to 33 percent and 200 percent improvement over its predecessor’s download and upload speeds, respectively.”
The specifications for this new modem are densely packed:
- Cat 12 (up to 600 Mbps) in the downlink
- Cat 13 (up to 150 Mbps) in the uplink
- Up to 4x4 MIMO on one downlink LTE carrier
- 2x2 MU-MIMO (802.11ac)
- Multi-gigabit 802.11ad
- LTE-U and LTE+Wi-Fi Link Aggregation (LWA)
- Next Gen HD Voice and Video calling over LTE and Wi-Fi
- Call Continuity across Wi-Fi, LTE, 3G, and 2G
- RF front end innovations
- Advanced Closed Loop Antenna Tuner
- Qualcomm RF360™ front end solution with CA
- Wi-Fi/LTE antenna sharing
Rumored phones that could end up running the Snapdragon 820 with this X12 modem include the Samsung Galaxy S7 and around 30 other devices, though final word is of course pending on shipping hardware.
Business Model Based on Partnerships
|Alexandru Voica works for Imagination Technologies. His background includes research in computer graphics at the School of Advanced Studies Sant'Anna in Pisa and a brief stint as a CPU engineer, working on several high-profile 32-bit processors used in many mobile and embedded devices today. You can follow Alex on Twitter @alexvoica.|
Some months ago my colleague Rys Sommefeldt wrote an article offering his (deeply) technical perspective on how a chip gets made, from R&D to manufacturing. While his bildungsroman production covers a lot of the engineering details behind silicon production, it is light on the business side of things; and that is a good thing because it gives me opportunity to steal some of his spotlight!
This article will give you a breakdown of the IP licensing model, describing the major players and the relationships between them. It is not designed to be a complete guide by any means and some parts might already sound familiar, but I hope it is a comprehensive overview that can be used by anyone who is new to product manufacturing in general.
The diagram below offers an analysis of the main categories of companies involved in the semiconductor food chain. Although I’m going to attempt to paint a broad picture, I will mainly offer examples based on the ecosystem formed around Imagination (since that is what I know best).
A simplified view of the manufacturing chain
Let’s work our way from left to right.
Traditionally, these are the companies that design and sell silicon IP. ARM and Imagination Technologies are perhaps the most renowned for their sub-brands: Cortex CPU + Mali GPU and MIPS CPU + PowerVR GPU, respectively.
Given the rapid evolution of the semiconductor market, such companies continue to evolve their business models beyond point solutions to become one-stop shops that offer more than for a wide variety of IP cores and platforms, comprising CPUs, graphics, video, connectivity, cloud software and more.
Qualcomm’s GPU History
Despite its market dominance, Qualcomm may be one of the least known contenders in the battle for the mobile space. While players like Apple, Samsung, and even NVIDIA are often cited as the most exciting and most revolutionary, none come close to the sheer sales, breadth of technology, and market share that Qualcomm occupies. Brands like Krait and Snapdragon have helped push the company into the top 3 semiconductor companies in the world, following only Intel and Samsung.
Founded in July 1985, seven industry veterans came together in the den of Dr. Irwin Jacobs’ San Diego home to discuss an idea. They wanted to build “Quality Communications” (thus the name Qualcomm) and outlined a plan that evolved into one of the telecommunications industry’s great start-up success stories.
Though Qualcomm sold its own handset business to Kyocera in 1999, many of today’s most popular mobile devices are powered by Qualcomm’s Snapdragon mobile chipsets with integrated CPU, GPU, DSP, multimedia CODECs, power management, baseband logic and more. In fact the typical “chipset” from Qualcomm encompasses up to 20 different chips of different functions besides just the main application processor. If you are an owner of a Galaxy Note 4, Motorola Droid Turbo, Nexus 6, or Samsung Galaxy S5, then you are most likely a user of one of Qualcomm’s Snapdragon chipsets.
Qualcomm’s GPU History
Before 2006, the mobile GPU as we know it today was largely unnecessary. Feature phones and “dumb” phones were still the large majority of the market with smartphones and mobile tablets still in the early stages of development. At this point all the visual data being presented on the screen, whether on a small monochrome screen or with the color of a PDA, was being drawn through a software renderer running on traditional CPU cores.
But by 2007, the first fixed-function, OpenGL ES 1.0 class of GPUs started shipping in mobile devices. These dedicated graphics processors were originally focused on drawing and updating the user interface on smartphones and personal data devices. Eventually these graphics units were used for what would be considered the most basic gaming tasks.

When Sebastian reviewed the LIVA X he focused on the performance of the device as an HTPC running Ubuntu ... before attempting to determine its effectiveness in creating a peanut butter and banana omelette, but that is a different story.
Overclocker's Club took a different tack, examining how it would perform for light gaming duties. On default settings the LIVA X managed 517 in Sky Diver, 1198 in Cloud Gate, 14200 in Ice Storm, and 9598 in Ice Storm Extreme. This would make it effective at playing mobile games or even playing through legacy games available through GoG or the Internet Archive; they tested CivV as a more modern title and while playable it wasn't great. Check out the full review for the other benchmark results.
"The ECS LIVA X surprised me with its small size and completely silent operation. I was able to surf the internet and do work on it very quickly. I enjoyed using it and experienced no problems with browsing the internet, using Office applications, or watching streaming videos on Netflix. Amazon Prime would occasionally lag a little – usually when the HUD would pop up."

Want to liven up your weekend? Forget college basketball, we all know that few things are more exciting than SEC filings - and oh boy do we have a great read for you! (OK, this one is actually interesting!)
Ah, legal documents...
NVIDIA has disclosed in their latest 10-K filing that none other than Samsung is manufacturing some of the company’s chips. TSMC has been the source of GPUs for both AMD and NVIDIA for some time, but this filing (the full document is available from the SEC website) has a very interesting mention of the suppliers of their silicon under the “Manufacturing” section:
"We utilize industry-leading suppliers, such as Taiwan Semiconductor Manufacturing Company Limited and Samsung Electronics Co. Ltd, to produce our semiconductor wafers."
Back in December NVIDIA commented on its lawsuit against Samsung for alleged IP theft, which only makes this partnership seem more unlikely. However even Apple (which has their own famous legal history with Samsung, of course) has relied on Samsung for some of the production of their A-series SoCs, including the current crop of A8 chips. Business is business, and Samsung Foundry has been a reliable source of silicon for multiple manufacturers - particularly during times when TSMC has struggled to meet demand at smaller process nodes.
Samsung's Current Semiconductor Offering
It is unclear at this point whether the wafers produced by Samsung Semiconductor are for NVIDIA’s mobile parts exclusively, or if any of the desktop GPUs were produced there rather than at TSMC. The partnership could also be attributed simply to scale, just as Apple has augmented A8 SoC supply with their rival’s fab while primarily relying on TSMC. It will be interesting to see just how pervasive the chips produced by Samsung are within the NVIDIA lineup, and what future products might be manufactured with their newest 14nm FinFET process technology.

Samsung has announced the new Galaxy S phones at MWC, and the new S6 and S6 Edge should be in line with what you were expecting if you’ve followed recent rumors.

As expected we no longer see a Qualcomm SoC powering the new phones, and as the rumors had indicated Samsung opted instead for their own Exynos 7 Octa mobile AP. The Exynos SoC’s have previously been in international versions of Samsung’s mobile devices, but they have apparently ramped up production to meet the demands of the US market as well. There is an interesting twist here, however.
The Exynos 7420 powering both the Galaxy S6 and S6 Edge is an 8-core SoC with ARM’s big.LITTLE design, combining four ARM Cortex-A57 cores and four Cortex-A53 cores. Having announced 14nm FinFET mobile AP production earlier in February the possibility of the S6 launching with this new part was interesting, as the current process tech is 20nm HKMG for the Exynos 7. However a switch to this new process so soon before the official announcement seemed unlikely as large-scale 14nm FinFET production was just unveiled on February 16. Regardless, AnandTech is reporting that the new part will indeed be produced using this new 14nm process technology, and this gives Samsung an industry-first for a mobile SoC with the launch of the S6/S6 Edge.
GSM Arena has specs of the Galaxy S6 posted, and here’s a brief overview:
- Display: 5.1” Super AMOLED, QHD resolution (1440 x 2560, ~577 ppi), Gorilla Glass 4
- OS: Android OS, v5.0 (Lollipop) - TouchWiz UI
- Chipset: Exynos 7420
- CPU: Quad-core 1.5 GHz Cortex-A53 & Quad-core 2.1 GHz Cortex-A57
- GPU: Mali-T760
- Storage/RAM: 32/64/128 GB, 3 GB RAM
- Camera: (Primary) 16 MP, 3456 x 4608, optical image stabilization, autofocus, LED flash
- Battery: 2550 mAh (non-removable)
The new phones both feature attractive styling with metal and glass construction and Gorilla Glass 4 sandwiching the frame, giving each phone a glass back.

The guys at Android Central (source) had some pre-release time with the phones and have a full preview and hands-on video up on their site. The new phones will be released worldwide on April 10, and no specifics on pricing have been announced.

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.
Introduction, Specs, and First Impressions
In our review of the original LIVA mini-PC we found it to be an interesting product, but it was difficult to identify a specific use-case for it; a common problem with the mini-PC market. Could the tiny Windows-capable machine be a real desktop replacement? That first LIVA just wasn't there yet. The Intel Bay Trail-M SoC was outmatched when playing 1080p Flash video content and system performance was a little sluggish overall in Windows 8.1, which wasn't aided by the limitation of 2GB RAM. (Performance was better overall with Ubuntu.) The price made it tempting but it was too underpowered as one's only PC - though a capable machine for many tasks.
Fast forward to today, when the updated version has arrived on my desk. The updated LIVA has a cool new name - the “X” - and the mini computer's case has more style than before (very important!). Perhaps more importantly, the X boasts upgraded internals as well. Could this new LIVA be the one to replace a desktop for productivity and multimedia? Is this the moment we see the mini-PC come into its own? There’s only one way to find out. But first, I have to take it out of the box.

Wearable tech shown at this year's CES by Intel included the Intel MICA and Basis PEAK wearables, but a blog post from ARM is reporting that a pair of these devices are powered by an ARM SoC.
The Intel MICA (Image credit: Intel)
ARM has posted pictures of teardowns from different wearable products, highlighting their presence in these new devices. The pictures we have taken from ARM's blog post show that it is not Intel at the heart of the two particular models we have listed below.
First is the Basis PEAK, and it actually makes a lot of sense that this product would have an ARM SoC considering Intel's aquisition of Basis occurred late in 2014, likely after the development of the PEAK had been completed.
The Basis PEAK (Image credits: Basis, ARM)
Of course it is likely that Intel has plans to integrate their own mobile chips into future versions of wearable products like the PEAK.
Of some interest however is the SoC within their own MICA luxury wearable.
The Intel MICA (Image credits: Intel, ARM)
For now, ARM is the industry standard for mobile devices and they are quick to point this out in their their blog post, writing "it’s important to remember that only ARM and its partners can meet the diversity requirements and fuel innovation in this space". Intel seems to be playing the "partner" role for now, though not exclusively as the company's mobile technology is powering the newest ASUS ZenFone, for instance.
