Is Samsung Readying A 10nm SoC?
Of course, it is that time of the year. Apple, Qualcomm, MediaTek and now Samsung will have 10nm SoCs ready for phones in early 2017. Of course Samsung wants to use its own 10nm SoC in the Galaxy S8 that is expected in late February 2017, but probably with a mix of 10nm Snapdragon too.
Samsung’s next generation Exynos’ name is very uninspired. You don’t call your much better chip just the Exynos 8895, but that might not be the final name.
The Korean giant went from Exynos 7420 for Galaxy S5 and first 14nm for Android followed a year after with Exynos 8890 still 14nm but witha custom Exynos M1 “Mongoose” plus Cortex-A53eight core combination.
The new SoC is rumored to come with a 4GHz clock. The same leak suggests that the Snapdragon 830 can reach 3.6 GHz which would be quite an increase from the 2.15Ghz that the company gets with the Snapdragon 820. Samsung’s Exynos 8890 stops at 2.6GHz with one or two cores running while it drops to 2.3 GHz when three of four cores from the main cluster run. Calls us sceptics for this 4GHz number as it sounds like quite a leap from the previous generation.
Let us remind ourselves that the clock speed is quite irrelevant as it doesn’t mean anything, and is almost as irrelevant as an Antutu score. It tells you the maximal clock of a SoC but you really want to know the performance per watt or how much TFlops you can expect in the best case. A clock speed without knowing the architecture is insufficient to make any analysis. We’ve seen in the past that 4GHz processors were slower than 2.5GHz processors.
The fact that Samsung continued to use Snapdragon 820 for its latest greatest Galaxy Note 7 means that the company still needs Qualcomm and we don’t think this is going to change anytime soon. Qualcomm traditionally has a better quality modem tailored well for USA, China, Japan and even the complex Europe or the rest of the world.

Graphene May Give Processors A Boost
Researchers at MIT have figured out that graphene, sheets of atom-thick carbon, could be used to make chips a million times faster.
The researchers have worked out that slowing the speed of light to the extent that it moves slower than flowing electrons can create an “optical boom”, the optical equivalent of a sonic boom.
Slowing the speed of light is no mean feat, but the clever folks at MIT managed it by using the honeycomb shape of carbon to slow photons to slow photons to several hundredths of their normal speed in a free space, explained researcher Ido Kaminer.
Meanwhile, the characteristics of graphene speed up electrons to a million metres a second, or around 1/300 of the speed of light in a vacuum.
The optical boom is caused when the electrons passing though the graphene reach the speed of light, effectively breaking its barrier in the carbon honeycomb and causing a shockwave of light.
As electrons move faster than the trapped light, they bleed plasmons, a form of virtual particle that represents the oscillation of electrons on the graphene’s surface.
Effectively, it is the equivalent of turning electricity into light. This is nothing new – Thomas Edison did it a century ago with fluorescent tubes – but it can efficiently and controllably generate plasmons at a scale that works with microchip technology.
The discovery could allow chip components to be made from graphene to enable the creation of light-based circuits. These circuits could be the next step in the evolution of chip and computing technology, as the transfer of data through light is far faster than using electrons in today’s chips, even the fast pixel-pushing ones.
So much faster that it’s “six orders of magnitude higher than what is used in electronics”, according to Kaminer. That’s up to a million times faster in plain English.
“There’s a lot of excitement about graphene because it could be easily integrated with other electronics,” said physics professor Marin Soljačić, a researcher on the project, who is confident that MIT can turn this theoretical experiment into a working system. “I have confidence that it should be doable within one to two years.”
This is a pretty big concept and almost sci-fi stuff, but we’re always keen to see smaller and faster chips. It also shows that the future tech envisioned by the world of sci-fi may not be that far away.

ARM Shows Off 10nm Chip
ARM’s collaboration with TSMC has finally born some fruit with the tapeout of a 10nm test chip to show off the company’s readiness for the new manufacturing process.
The new test chip contains ARM’s yet-to-be-announced “Artemis” CPU core which is named after a goddess who will turn you into deer and tear you apart with wild dogs if you ever see her. [The NDA must have been pretty tough on this chip.ed]
In fact things have been ticking along on this project for ages. ARM discloses that tapeout actually took place back in December last year and is expecting silicon to come back from the foundry in the following weeks.
ARM actually implemented a full four-core Artemis cluster on the test chip which should show vendors what is possible for their production designs. The test chip has a current generation Mali GPU implementation with 1 shader core to show vendors what they will get when they use ARM’s POP IP in conjunction with its GPU IP. There is also a range of other IP blocks and I/O interfaces that are used to validation of the new manufacturing process.
TSMC’s 10FF manufacturing process is supposed to increase density with scaling’s of up to 2.1x compared to the previous 16nm manufacturing node. It also brings about 11-12 per cent higher performance at each process’ respective nominal voltage, or a 30 per cent reduction in power.
ARM siad that comparing a current Cortex A72 design on 16FF+ and an Artemis core on 10FF on the new CPU and process can halve the dynamic power consumption. Currently clock frequencies on the new design are still behind the older more mature process and IP, but ARM expects this to improve as it optimizes its POP and the process stabilizes.

TSMC’s FinFet Coming In 2015?
TSMC has announced that it will begin volume production of 16nm FinFET products in the second half of 2015, in late Q2 or early Q3.
For consumers, this means products based on TSMC 16nm FinFET silicon should appear in late 2015 and early 2016. The first TSMC 16nm FinFET product was announced a few weeks ago.
TSMC executive CC Wei said sales of 16nm FinFET products should account for 7-9% of the foundry’s total revenue in Q4 2015. The company already has more than 60 clients lined up for the new process and it expects 16nm FinFET to be its fastest growing process ever.
Although TSMC is not talking about the actual clients, we already know the roster looks like the who’s who of tech, with Qualcomm, AMD, Nvidia and Apple on board.
This also means the 20nm node will have a limited shelf life. The first 20nm products are rolling out as we speak, but the transition is slow and if TSMC sticks to its schedule, 20nm will be its top node for roughly a year, giving it much less time on top than earlier 28nm and 40nm nodes.
The road to 10nm
TSMC’s 16nm FinFET, or 16FinFET, is just part of the story. The company hopes to tape out the first 10nm products in 2015, but there is no clear timeframe yet.
Volume production of 10nm products is slated for 2016, most likely late 2016. As transitions speed up, TSMC capex will go up. The company expects to invest more than $10bn in 2015, up from $9.6bn this year.
TSMC expects global smartphone shipments to reach 1.5bn units next year, up 19 percent year-on-year. Needless to say, TSMC silicon will power the majority of them.
TSMC Testing ARM’s Cortex A57
ARM and TSMC have manufactured the first Cortex A57 processor based on ARM’s next-gen 64-bit ARMv8 architecture.
The all new chip was fabricated on TSMC’s equally new FinFET 16nm process. The 57 is ARM’s fastest chip to date and it will go after high end tablets, and eventually it will find its place in some PCs and servers as well.
Furthermore the A57 can be coupled with frugal Cortex A53 cores in a big.LITTLE configuration. This should allow it to deliver relatively low power consumption, which is a must for tablets and smartphones. However, bear in mind that A15 cores are only now showing up in consumer products, so it might be a while before we see any devices based on the A57.
In terms of performance, ARM claims the A57 can deliver a “full laptop experience,” even when used in a smartphone connected to a screen, keyboard and mouse wirelessly. It is said to be more power efficient than the A15 and browser performance should be doubled on the A57.
It is still unclear when we’ll get to see the first A57 devices, but it seems highly unlikely that any of them will show up this year. Our best bet is mid-2014, and we are incorrigible optimists. The next big step in ARM evolution will be 20nm A15 cores with next-generation graphics, and they sound pretty exciting as well.
TSMC And Imagination Team Up
TSMC and Imagination Technologies announced the next step in their tech collaboration in an effort to develop Imagination’s next generation PowerVR 6-series GPUs.
The new GPUs are still not ready for prime time, but they should be used in future SoC designs, including those stamped out using TSMC’s 16nm FinFET process. The two companies will work to create new reference system designs, utilizing high bandwidth memory standards and TSMC’s 3D IC technology.
As GPU muscle becomes more important for next generation SoCs, designers need more advanced and more complex processes, such as TSMC’s 16FinFET.
“Through advanced projects initiated under this partnership, Imagination and TSMC are working together to showcase how SoCs will transform the future of mobile and embedded products,” said Hossein Yassaie, CEO of Imagination.
TSMC VP Cliff Hou argued that the need for high performance mobile GPUs will drive silicon processes in the future, much in the same way CPU development pushed new processes in the nineties.
Samsung Goes Star-ups
Samsung will put $1.1 billion towards venture capital funding of semiconductor firms.
The company said that it will commit the research and development funding through its Samsung Venture Americas branch and Catalyst Fund investment operations, according to multiple reports.
The investment is set to target semiconductor design and manufacturing. The company will look to fund startups that can assist its hardware units and will open a new R&D facility in Silicon Valley.
The announcement comes as Samsung is seeing its revenues hit record levels. The company reported quarterly profits of 7.5 billion to close out 2012 and sales from Samsung’s handset unit reached record levels.
Analysts believe that the company now controls nearly 23 percent of the smartphone market. The jump in hardware sales has brought with it a healthy appetite for components. Earlier this month Samsung passed Apple to become the world’s largest single user of semiconductor chips.
Samsung has recently stepped up its investment activities, with the firm buying storage vendor Nvelo and last week buying a small stake in Wacom, best known for its touchpad and stylus input technology. With the firm looking to invest in startups, it is perhaps looking to follow in Apple’s footsteps, which kickstarted its chip design efforts by buying PA Semiconductor and later Intrinsity, and invested in Imagination Technologies.
TSMC 20nm Processors In High Demand
TSMC believes demand for next-generation 20nm chips will be even higher than demand for current 28nm products.
Speaking in a conference call, TSMC CEO Morris Chang said the volume of 20nm SoCs built next year will be greater than 28nm volume in 2012 and by 2015 it should be greater than 28nm volume in 2013.
TSMC hopes to start 20nm production in the latter part of the year. The company is constructing two new facilities at Fab 15 and it hopes to start 20nm production in both simultaneously. We could be in for a quick ramp.
TSMC will offer only one version of the 20nm process, compared to four versions of the 28nm process. This should also allow it to ramp up volume production faster, reckons Xbit Labs.
TSMC To Boost 28nm Production
TSMC is able to make chips using 28nm process technology at a speedier pace that it originally anticipated. This means that the chipmaker will likely be able to meet demand for existing orders and start accepting new designs.
TSMC promised to increase its 28nm capacity to 68 thousand 300mm wafers per month by the end of the year. It did this by ramping up fab 15/phase 2 to 50,000 300mm wafers a month. According to the Taiwan Economic News it looks like the outfit managed to beat its own projections, which should be good news for customers like AMD, Nvidia and Qualcomm. Well not AMD of course. It just told Globalfoundries to stop making so many of its chips so it can save a bit of money.
But it looks like TSMC is flat out. In November the fab 15/phase 2 processed 52,000 wafers. When combined with fab 15/phase 1, TSMC should be able to process 75 – 80, 000 300mm wafers using 28nm process technologies this month. TSMC produces the majority of 28nm chips at fab 15, which will have capacity of more than 100,000 300mm wafers per month when fully operational.
TSMC Makes Expansion Plans
TSMC is expected to spend $10 billion next year in capital works as Apple plans to contract the outfit to build its next-generation processors.
According to the Chinese-language Economic Daily News TSMC has informed the equipment suppliers of its decision to hike capital expenditure for 2013 to US$10 billion. This indicates that TSMC has overcome technical problem with 20nm process, which Apple’s next-generation processors are said to use.
It also suggests that Jobs’ Mob is speeding up its reduction of work it gives Samsung. Apple has reportedly sent around 200 design engineers to help TSMC get familiar with the company’s next-generation processor designs at TSMC’s facility in Central Taiwan Science Park.
