Samsung, Exynos, processor, MWC

Plus new camera sensors and radio chipsets

Mobile World Congress isn't just big smartphone announcements — like any big trade show there are announcements small and big, consumer and technical. This one trends more on the side of technical, and it's Samsung's latest application processors: the Exynos 5422 and Exynos 5260.

We'll start with the Exynos 5422, an octa-core chipset that, like previous Samsung octa-core processors, is really more like two quad core processors combined. The Exynos 5422 includes four powerful ARM Cortex-A15 cores that can be clocked up to a blazing 2.1GHz, and four ARM Cortex-A7 cores running at up to 1.5GHz for lighter loads. Samsung claims the Exynos 5422 can "deliver up to 34 percent higher performance than in previous Exynos Octa models." All this power means the processor can handle 4K displays with aplomb, though it's not likely we're going to see those any time soon, so that extra oomph can instead be directed at other tasks. The 28-nanometer process used to fabricate the Exynos 5422 is said to result in a 10% reduction in power consumption.

The Exynos 5260, on the other hand, is a hexa-core processor with two big 1.7GHz ARM Cortex-A15 cores paired with four 1.3GHz ARM Cortex-A7 cores. The 6-core model isn't quite as powerful as its 8-core brother, having both a lower clock speed and fewer cores, but Samsung still projects it to be able to handle displays all the way up to WQXGA (2560x1600). The Exynos 5260 is currently in production, while the Exynos 5422 is scheduled to start mass production in the first quarter of the year, so be looking for both in future Samsung products.

Apart from the new Exynos 5 chips, Samsung's also pumping out new CMOS image sensors (i.e. the sensors that go into smartphone cameras). The new ISOCELL sensors were first previewed back in September 2013, and now they're beginning production on both 13- and 16-megapixel. Samsung says the sensors will have 1.12-micrometer pixels:

By incorporating ISOCELL, the image sensor will have 30 percent decrease in crosstalk; 30 percent increase in full well capacity; and 20 percent wider chief ray angle.

The 13-megapixel ISOCELL sensor utilizes what "Smart Wide Dynamic Range" technology which allows for multiple-exposure HDR imagery to be captured at 30 frames per second. The 16-megapixel sensor, however, features a 16:9 aspect ratio (standard camera sensors are built at 4:3), mimicking the aspect ratio of most smartphone screens, modern computer displays, and televisions. By going with a wider aspect ratio, the entire 16-megapixel array can be utilized when recording video, which this sensor does at 60 frames per second. The 13-megapixel sensor is due to begin manufacturing in the first quarter, with the 16-megapixel version hitting the assembly line the following quarter.

Apart from that, Samsung's also produced a third-generation NFC chip, the first to use a 45-nanometer embedded flash process for lower power consumption, plus it uses "the industry's smallest antenna with enhanced radio frequency performance." There's also a new low-power Wi-Fi solution — the S5N2120 — designed for connected devices with a small footprint and low power draw.

Very nice. Is it 64-bit?

Nope.

Looks good.

I'm not interested in a 4K (or even 2K) display on a phone -- seems like a waste of battery, memory and CPU handling that kind of resolution. I do see the use of being able to output 4K when connected to a larger display device such as a 4K TV, though. I think that Tegra Shield can do this?

ronnypoo says:

Thought the same as well. Supposedly these will improve the sensors. Can't wait to see how much more awesome the note 4's camera is compared to the nearly perfect camera on the note 3 :)

What's the point of having this much power. I understand quad core but really who needs this much computing power. Then again I guess it's to save battery life unless they offered the option to have all 8 cores running at once which that would be unnecessary

The future is using a phone as a secure device to be used to do all basic personal computing. For example - Samsung can sell a smart TV with a phone dock. You can just dock your phone and have a keyboard and mouse peripheral and use it to do word processing, photo editing, movie editing, gaming, etc. You can also video chat and answer calls using this setup.

However, the power user and advanced gamer will still need a custom desktop/laptop.

this is true... although a true perfect future would be a completely connected society. Our devices are merely empty shells with radio components to send all the data for storage and processing to the cloud.

So is the ISOCELL sensor also coming in the S5? many rumors and sample photos circulating have pointed towards that, is the S5 gonna be using the firstfruits of the ISOCELL 16mp sensor?

The only reference I have seen to this is AnandTech: http://www.anandtech.com/show/7768/galaxy-s5-initial-thoughts The question for me is how the camera module including these new features (phase detection auto-focus, real-time HDR and possibly ISOCELL technology) compare to competitors' cameras that include OIS in the real world under different lighting conditions.

For what phones do currently, this may seem a bit overkill. However, in the (near-ish) future when wearables and other peripherals will be communicating with the phone in your pocket, the more powerful and efficient these processors are the better.
It's not so much about what it does today, but what it will be required to do in the future.

I imagine that the next note 4 is going to be a beast, and with these it should run smooth as silk. Lol, wait it'll have tw.. Nevermind.
