Upcoming 32-bit SoCs

An Introduction To The Major ARM-Based SoCs
By , Dorian Black

All four companies already sell powerful SoCs. But the market doesn’t stand still, and some of them are preparing to release revolutionary processors by the end of 2014, while others continue improving on already-successful formulas.

Qualcomm Snapdragon 805

As mentioned, Qualcomm was surprisingly slow to respond to Apple’s ARMv8-based A7. The 64-bit SoCs it already announced for 2014 are lower-end, while the high-end ones won’t arrive until next year. Even then, they're off-the-shelf reference cores from ARM.

That’s a little strange, to say the least, from the company that assumed its leadership position by pushing the envelope and taking full advantage of ARM’s latest instruction sets, and by shipping new designs even before reference ARM-based solutions started emerging. That gave it the early adopter advantage that made Snapdragon so successful. But for some reason, not only did Apple’s Cyclone announcement catch Qualcomm by surprise, but a year later there's still no proprietary architecture based on the ARMv8 ISA.

For 2014, it prepared a slight improvement of Snapdragon 801, apparent from the Snapdragon 805 designator. The CPU is based on the Krait 450 design now operating at up to 2.7 GHz.

The GPU gets a bigger boost with Adreno 420 graphics, though it's likely nowhere near as powerful as Nvidia’s Kepler-based solution, given a purported 40-percent speed-up compared to Adreno 330. Tegra K1 should be at least twice as fast as Adreno 330 (166 GFLOPS versus 365).

Qualcomm’s offerings for this year don’t seem as compelling or competitive as I’d like them to be, but the company profits from being a long-term and trusted partner to many OEMs, so it continues raking in the design wins.

Samsung Exynos 5433

Not a lot is known about the Exynos 5433, but it’s rumored to arrive later this year in Samsung's Galaxy Note 4, which would make it Samsung's highest-end SoC for 2014. Leaked benchmarks put it ahead of Qualcomm’s Snapdragon 805 in AnTuTu, though still below Nvidia’s Denver-based Tegra K1 (expected to surface in the fall).

What we might expect from the 5433 is another eight-core chip, probably built using a cluster of four Cortex-A7s and another cluster of four Cortex-A15s, perhaps manufactured at 20 nm. So, it should offer higher performance and better efficiency than the previous generation Exynos SoC.

Although an ARMv8-based Exynos has been rumored since late last year, it’s unlikely we'll see it in 2014. That processor will purportedly benefit from 14 nm lithography, and Samsung probably won't have that ready for mass production in the next few months. At best, we may hear more in early 2015, just in time for a Galaxy S6 (which could also make the Exynos 6 Octa name more appropriate, if that’s what it ends up being called).

    tegra and zune!?! rofl!
    the stark soc seems to have vanished from the latest soc roadmap... wonder what happened to it....
    wonder why mediatek, allwinner left out of the "big players" while nvidia in nowhere on the "competitive landscape" or anything that qualifies as such. :pt1cable:

    Yay! ARM chips!
    Half the cost and half the performance!

    Power efficient does not mean performance wise ...

    The Starks have been dropping like flies. Maybe Nvidia got worried HBO would finish killing them off in the fifth season.

    Haven't heard peep about Stark for a very long time, but the followup article, scheduled for next week, focuses on lesser-known Chinese ARM-based SoCs ;)

    I'm interested to see how well the Tegra K1 performs in market. It would be great if it was successful, because that will push Qualcomm and other manufacturers to develop more powerful chips as well. Competition benefits us consumers, and technology as a whole.

    As ARM chips become more powerful and x86 chips become more power efficient, it won't be long until the two of them meet. I'm curious to see which format will win that war. One thing's for sure, the next decade will be a very exciting time for mobile computing.

    The Shield Tablet murders its battery in just over two hours when its IGP gets pushed to its limits so I doubt the K1 will be particularly popular for products where small size and long battery life are priorities. If it does manage to succeed, it will be in larger devices that can accommodate larger batteries like Chromebooks and mobile devices specifically designed for mobile gamers.

    Tegra 4 was actually pretty powerful graphics wise. The problem is that it wasn't power efficient and thus got throttled when used in a smartphone. The Shield on the other hand actually lets it go full out, it's even got a small heatsink and airvents which do get hot after you've been using it for awhile. The K1 is similiar, it provides great visuals and is very powerful, but sucks power and generates heat doing so.

    everyone reports that 5433 will be 64-bit: http://www.droid-life.com/2014/08/20/galaxy-note-4-powered-by-64-bit-exynos-5433-benchmarked-only-beat-by-one-other-chipset/

    Is 702p a typo, or is Apple going to break another standard?

    It's not related to the HBO show. Rather related to IRON MAN. As in, Tony Stark. His movies are still doing very well (a billion well that is, and so is downey's salary at about $80mil+ for ironman3...LOL). I think it's just delayed after erista/parker chips. These are superhero's, not hbo characters.

    I believe most of the moves are due to NV (and others) not being able to count on fabs to get what they wanted in their chips (based on previous history), so we have a few stopgap chips now as CYA stuff I guess. A few years ago they probably started wondering, will they get to 20nm ok or not, will they get to 16/14 or not, will finfet be in or out and at what node, will we be able to do 3d stacked ram etc etc. Tons of questions so they put more chips on the roadmap just in case. Wise IMHO, based on fab track records, even if they do seem to be getting their crap together finally for these last few big moves at TSMC/Samsung/GF. TSMC seems to be on schedule and GF/Samsung have swappable process etc now since working together with IBM.

    Maybe you guys should get on the right roadmap instead of the wrong show ;)

    But you don't HAVE to run it full out as anandtech showed, you can drop it to a 30fps limit (still beating everyone else) and avoid the problems you're talking about with battery and power sucking. They also mentioned it isn't bad on heat.
    http://anandtech.com/show/8354/tegra-k1-lands-in-acers-newest-chromebook
    Very battery efficient at 11.5-13hrs in a chromebook.

    http://anandtech.com/show/8329/revisiting-shield-tablet-gaming-ux-and-battery-life
    "In addition to the low GPU clocks, we see that the skin temperatures never exceed 34C, which is completely acceptable."
    So once you drop the perf some instead of running the chip in a way NO GAME will run it (maxed permanently for a test), the temps drop and so does battery. Games don't do what their benchmark does as they clearly showed in the "revisiting shield" article. Which comically anandtech make not so easy to find...ROFL. K1 tag won't get it, you have to hit joshua's articles. AMD's checks are still coming I guess...ROFL. ***cough, AMD PORTAL, cough ***

    If you cannot use the chip for more than 50% of what it is worth without murdering the battery, might as well make the chip 50% weaker in the first place and not have to bother with throttling to make battery life reasonable; it would still beat everything else currently on the market without having to bother with artificially capping its performance. The chip would be a buck or two cheaper to manufacture and yields would likely be better on top of that.

    Why remove the OPTION to run full out if desired? That is ridiculous. I can plug in and use FULL power all day, which is how most would use it if hooked to a TV as noted in reviews (for gaming with a gamepad).

    You're arguing to limit choice of something they are giving you for free...LOL. Ok. Whatever. Manufacturers can put the chip at whatever they want, as Acer did running it at 2.1ghz instead of 2.3ghz, thus giving it massive battery life for their chromebook. They can also govern the clocks of the gpu any way they want (sure I can override whatever they do in most cases, but they can set it at whatever for sale). Should AMD sell all their gpus with less power because they use more watts than NV cards? That's dumb and they wouldn't be competitive then.

    The point of having the power in there is you can use it WHEN DESIRED (like next year or the year after when games using this kind of power actually land). Your way, would have you require a NEW device at that point because they chose to artificially limit the soc forcing a new purchase. Your argument is ridiculous and even at 750 you get better battery than 852mhz it's clocked at, no need to drop it to half.

    The user has no idea anything is happening anyway. Bother? Bother who? Logic in the device does all this for you, just like a desktop drops speed when not used etc. No difference here. The ONLY correct move is giving me full power that won't damage the device (if you get to damage levels THEN and only THEN is it giving me too much). I'd rather have a super-powered device I could plug in and use for an extra year or two in really intense gaming, than be forced to buy a new product because they limited me for ABSOLUTELY no reason. I want the fastest clocks my gpu in my pc can run at, unless it damages the unit. ALWAYS. I'll gladly turn it down if I don't want as much heat in my room etc (or too noisy), rather than NOT have the ability to use the free power.

    By your logic they should just start shipping all current laptops as half speeds (heck ship everything at half), for great battery...LOL. What? Whatever. I'll plugin when needed and run intense games IN the house where I have a power outlet.
