I got to spend some time with the brand new Samsung Galaxy S7 and S7 Edge phones at MWC this week in Barcelona. Is this your next Android flagship phone?

No one is more excited to see the Snapdragon 820 processor in the Galaxy S7 (in some regions) than Qualcomm and Qualcomm's investors. Missing the S6 design win completely was a big blow to the SD 810 but the move to FinFET technology and a new SoC design have put the SD 820 back in the driver's seat for flagship smartphones it seems. While talking with Qualcomm's Peter Carson, Senior Director of Marketing and Modems, I learned quite a bit about the X12 LTE modem integration with the Galaxy S7 as well. As it turns out, the application processor itself isn't the only thing that has impressed OEMs or that will benefit consumers.
Modem marketers have a problem - quantifying the advantages of one LTE modem over another can be troublesome and complex. It's not as simple as X% faster or X% longer battery life, though those aspects of performance see improvement with better modem technology. And while of course the new announcement of Gigabit LTE is getting all the media attention at Mobile World Congress this week, there is a lot of excitement internally about the shipping implementation of the S7's modem.
The Galaxy S7 encompasses the most advanced Qualcomm TruSignal antenna technology implementation to date, combining several features to add real-world benefits to the cellular performance of the device.
First, the S7 will feature the most advanced version of the antenna tuner including a closed loop feedback cycle that will tweak antenna properties in real time based on sensor data and current signal properties. If the proximity sensor is activated or you are rotating or moving the mobile device, the receiver can adjust antenna properties to improve signal reliability measurably.
The best examples fall on the cell edge, where dropped calls are common and low voice quality are found. You can improve the gain of the antenna, that is adversly affected by simply holding the device, for much better reliability and even data throughput. That means fewer dropped calls and network drops for users that have moderate service reliability. Voice quality will get better as well, as the error rates that cause data loss in low signal areas will be reduced.
But even users that have a good signal can get benefits from the tech - gains of just 2-3 db will allow the modem and receiver to go into a lower power state, reducing 20% of the modem power draw. That won't equate to 20% total system battery life improvement but users that depend on their phones for extended use will see benefits from this integration.
Another TruSignal feature included in this modem implementation is smart transmit antenna switching. The simple explanation here is that the modem can swap which antennas are in receive and transmit modes in order to improve the transmit (upload) performance by as much as 10db! Based on properties of the antenna signal, position of the device and if you are in a heavy upload workload (posting some photos to Facebook, a video to YouTube), TruSignal allows the modem to change in real-time.
These techniques are additive so Galaxy S7 owners will find that both the antenna tuner and antenna switching are going to move the cellular performance forward, though Qualcomm isn't saying if ALL implementation of Samsung's new flagship smartphone will implement the features. I would guess that we'll see this on the Snapdragon 820 + X12 powered models only,
but I haven't learned yet which modem the Exynos-powered versions are using yet. Turns out the versions of the S7 that utilize the Samsung Exynos SoC are using a non-Qualcomm modem, so they will not support the features seen here.

The follow-up to the Samsung Galaxy S6 is already being rumored, which people are obviously calling the Galaxy S7. The last two phones were unveiled at Mobile World Congress in Barcelona, Spain, which takes place in late February / early March. Information coming out in November is a bit... early. Some sites believe that Samsung will announce the phone in January, but who knows? Some of the rumors are interesting, though.
The one that catches my attention is the potential inclusion of a microSD card slot. External storage is rare these days, with Google removing it from their Nexus line and severely limiting what apps can do with the contents. That said, Android 6.0, recently released for a few devices, made further changes to increase its capabilities. You can now use SD cards as internal storage, but only if you agree to format and encrypt the storage to use only on that device. While the recent batch of Nexus phones don't include a microSD card slot, the changes might be enough to sway third-party manufacturers to include a slot.
As a developer, it would certainly be nice, especially if you intend to develop software that uses an SD card. Makes sense, right? Purchasing a developer phone that has all the features you might want to target?
Speaking of developer phones, the upcoming device should have a top-of-the-line processor in it. Reports are split between the Snapdragon 820 and the Exynos 8890. If it's the latter, availability is expected Q1 2016; the former started sampling a few months ago and was launched on November 11th. As such, SoC availability should be ready if Samsung intends to launch the phone early, regardless of the chosen chip, but that's probably not the limiting factor. It is also entirely possible that Samsung could include different processors for different markets. Qualcomm was absent from the Galaxy S6 line, but the S5 had some sub-models using Qualcomm processors and others Samsung's own implementation.
Either way, they are fast processors that support OpenGL ES 3.1 + AEP at the very least. The Adreno 530 is rated for about 550 GFLOPs, which is a tiny bit faster than a GeForce 9800 GT, although with Vulkan-level feature support (provided correct drivers). Thankfully Google has been more friendly to Khronos-based standards, and Samsung even more so.
When will we know for sure? Don't know. How much will it cost? Don't know. What will it be officially called? Don't know, but anything other than Galaxy S7 would be surprising. Would it make sense for Samsung to shake up the date and other long-running details? Well, the Galaxy S6 launch was lackluster, so this would be the most likely time for them to be squirrely. We'll see.
Introduction and Specifications
Had you asked me just a few years ago if 6-inch phones would not only be a viable option, but a dominant force in the mobile computing market, I would have likely rolled my eyes. At that time phones were small, tablets were big, and phablets were laughed at. Today, no one is laughing at the Galaxy Note 4, the latest iteration in Samsung’s created space of larger-than-you-probably-thought-you-wanted smartphones. Nearly all consumers are amazed by the size of the screen and the real estate this class of phone provides but some are instantly off put by the way the phone feels in the hand – it can come off as foreign, cumbersome, and unusable.
In my time with the new Galaxy Note 4 – my first extended-use experience with a phone of this magnitude – I have come to see the many positive traits that a larger phone can offer. There are some trade-offs of course, including the pocket/purse viability debate. One thing beyond question is that a large phone means a big screen. One that can display a large amount of data whether that be on a website or in a note-taking application. The extra screen real estate can instantly improve your productivity. To that end Samsung also provides a multi-tasking framework that lets you run multiple programs in a side-by-side view, similar to what the original version of Windows 8 did. It might seem unnecessary for an Android device, but as soon as you find the situation where you need it going back to a device without it can feel archaic.
A larger phone also means that there is more room for faster hardware, a larger camera sensor, and a bigger battery. Samsung even includes an active stylus called the S-Pen in the body of the device – something that few other modern tablets/phablets/phones feature.

EVGA GTX 750 Ti ACX FTW
The NVIDIA GeForce GTX 750 Ti has been getting a lot of attention around the hardware circuits recently, but for good reason. It remains interesting from a technology stand point as it is the first, and still the only, Maxwell based GPU available for desktop users. It's a completely new architecture which is built with power efficiency (and Tegra) in mind. With it, the GTX 750 Ti was able to push a lot of performance into a very small power envelope while still maintaining some very high clock speeds.
NVIDIA’s flagship mainstream part is also still the leader when it comes to performance per dollar in this segment (for at least as long as it takes for AMD’s Radeon R7 265 to become widely available). There has been a few cases that we have noticed where the long standing shortages and price hikes from coin mining have dwindled, which is great news for gamers but may also be bad news for NVIDIA’s GPUs in some areas. Though, even if the R7 265 becomes available, the GTX 750 Ti remains the best card you can buy that doesn’t require a power connection. This puts it in a unique position for power limited upgrades.
After our initial review of the reference card, and then an interesting look at how the card can be used to upgrade an older or under powered PC, it is time to take a quick look at a set of three different retail cards that have made their way into the PC Perspective offices.
On the chopping block today we’ll look at the EVGA GeForce GTX 750 Ti ACX FTW, the Galaxy GTX 750 Ti GC and the PNY GTX 750 Ti XLR8 OC. All of them are non-reference, all of them are overclocked, but you’ll likely be surprised how they stack up.

The GALAXY GTX 780 Hall of Fame Edition is more than just a pretty white PCB, the GPU runs at a Boost Clock of 1.1GHz which is a full 200MHz above stock out of the box, after tweaking [H]ard|OCP managed to get it to 1376MHz but backed off to an even 1.3GHz to enable the RAM to run at 6.3GHz. When testing at that maximum speed this card could gp head to head with the mighty TITAN and provide the same quality of game play, a rather impressive performance for a less expensive card. That showing as well as the overall design of the card and unique look helped net the GTX 780 HOF a Gold Award!
"If you are interested at all in the fastest GeForce GTX 780 video card we’ve seen out-of-the-box yet, then take a look at GALAXY’s GeForce GTX 780 Hall of Fame Edition. You’ll also find the highest overclock ever achieved on a GTX 780 waiting for you with this video card. You don’t want to miss this."

I remember the first time I saw a white PCB - it was on a Soyo motherboard built on a chipset that very few people reading this post today will remember. Our friends at Galaxy just sent over word that its new GeForce GTX 780 3GB HOF (Hall of Fame) Edition card was now shipping and available at Amazon.com and TigerDirect.com sporting a fantastic looking white PCB!
As you probably know the GeForce GTX 780 is based on the same GK110 GPU as the GTX TITAN with fewer CUDA cores enabled and with a 3GB frame buffer it is definitely a step above other single-GPU offerings available (except the TITAN obviously). Even better, the HOF Edition from Galaxy is overclocked to a base clock of 1006 MHz compared to the reference speed of 863 MHz!! Galaxy claims this is the highest clocked air-cooled GTX 780 in the world!
