Hardware Experience

Seeing Ryan transition from being a long-time Android user over to iOS late last year has had me thinking. While I've had hands on with flagship phones from many manufacturers since then, I haven't actually carried an Android device with me since the Nexus S (eventually, with the 4.0 Ice Cream Sandwich upgrade). Maybe it was time to go back in order to gain a more informed perspective of the mobile device market as it stands today.

So that's exactly what I did. When we received our Samsung Galaxy S7 review unit (full review coming soon, I promise!), I decided to go ahead and put a real effort forth into using Android for an extended period of time.

Full disclosure, I am still carrying my iPhone with me since we received a T-Mobile locked unit, and my personal number is on Verizon. However, I have been using the S7 for everything but phone calls, and the occasional text message to people who only has my iPhone number.

Now one of the questions you might be asking yourself right now is why did I choose the Galaxy S7 of all devices to make this transition with. Most Android aficionados would probably insist that I chose a Nexus device to get the best experience and one that Google intends to provide when developing Android. While these people aren't wrong, I decided that I wanted to go with a more popular device as opposed to the more niche Nexus line.

Whether you Samsung's approach or not, the fact is that they sell more Android devices than anyone else and the Galaxy S7 will be their flagship offering for the next year or so.

Samsung's tiny BGA based SSD, destined for your tablet and smartphone

Subject: General Tech | March 23, 2016 - 12:10 PM |
Tagged: Samsung, ssd, BGA

Instead of the standard pin grid array, Samsung's PM971 SSD uses BGA which allows them to for a much smaller overall size, albeit at the cost of it being permanently soldered to a circuit motherboard.  The three models, 128GB, 256GB and 512GB, will each be smaller than an SD card which is why these SSDs will be able to be used in future generations of small mobile devices.  This not only foretells of a significantly higher storage capacity for your phone but also a faster one as Samsung's PR describes sequential read speeds of up to 1500MBps and sequential writes at 600MBps, or if you prefer, 190K random read IOPS and 150K random write IOPS.  They haven't really given any details beyond those stats but you can try to glean some more information from the Japanese language article which The Inquirer links to in their story here.

"SAMSUNG HAS been showing off what it believes is the answer to the question of how to squeeze even more out of smartphone and tablet form factors. And with blazing speeds of 1500MBps it's hard to argue."

Here is some more Tech News from around the web:

Introduction

Since Samsung’s August 2015 announcement of their upcoming 48-layer V-NAND, we’ve seen it trickle into recent products like the SSD T3, where it enabled 2TB of capacity in a very small form factor. What we have not yet seen was that same flash introduced in a more common product that we could directly compare against the old. Today we are going to satisfy our (and your) curiosity by comparing a 1TB 850 EVO V1 (32-layer - V2) to a 1TB 850 EVO V2 (48-layer - V3).

**edit**

While Samsung has produced three versions of their V-NAND (the first was 24-layer V1 and only available in one of an enterprise SSDs), there have only been two versions of the 850 EVO. Despite this, Samsung internally labels this new 850 EVO as a 'V3' product as they go by the flash revision in this particular case.

**end edit**

Samsung’s plan is to enable higher capacities with this new flash (think 4TB 850 EVO and PRO), they also intend to silently push that same flash down into the smaller capacities of those same lines. Samsung’s VP of Marketing assured me that they would not allow performance to drop due to higher per-die capacity, and we can confirm that in part with their decision to drop the 120GB 850 EVO during the switch to 48-layer in favor of a planar 750 EVO which can keep performance up. Smaller capacity SSDs work better with higher numbers of small capacity dies, and since 48-layer VNAND in TLC form comes in at 32GB per die, that would have meant only four 48-layer dies in a 120GB SSD.

(Similar analysis on 32-Layer V-NAND here)

Other companies have tried silently switching flash memory types on the same product line in the past, and it usually does not go well. Any drops in performance metrics for a product with the same model and spec sheet is never welcome in tech enthusiast circles, but such issues are rarely discovered since companies will typically only sample their products at their initial launch. On the flip side, Samsung appears extremely confident in their mid-line flash substitution as they have voluntarily offered to sample us a 1TB 48-layer 850 EVO for direct comparison to our older 1TB 32-layer 850 EVO. The older EVO we had here had not yet been through our test suite, so we will be comparing these two variations directly against each other starting from the same fresh out of the box and completely unwritten state. Every test will be run on both SSDs in the same exact sequence, and while we are only performing an abbreviated round of testing for these products, the important point is that I will be pulling out our Latency Percentile test for detailed performance evaluation at a few queue depths. Latency Percentile testing has proven itself far more consistent and less prone to data scatter than any other available benchmark, so we’ll be trusting it to give us the true detailed scoop on any performance differences between these two types of flash.

Read on for our comparison of the new and the old!
(I just referred to a 3D Flash part as 'old'. Time flies.)

Samsung Curved 1080p Monitors First with AMD FreeSync over HDMI

Subject: Displays | March 2, 2016 - 05:17 PM |
Tagged: amd, freesync, hdmi, Samsung

Earlier this week Samsung formally made a couple of announcements for new monitors due out this spring. The CF591 and CF390 range in size from 23 to 27 inches, mating a 1920x1080 resolution with an 1800R curvature and an attractive design. Even better news for gamers, all of the monitors in these two series will offer AMD's variable refresh rate technology known as FreeSync over HDMI.

The specifications of the monitors are interesting in their own light. The CF390 will be available in both 23.5-in and 27-in varieties, with a 1920x1080 resolution on a VA panel, a 4ms response time rating and a maximum brightness of 250 nits. The VA technology allows for solid viewing angles and color reproduction though all of them are limited to a 60Hz maximum refresh rate. The CF591 monitor is only available in a 27-in variety, shares almost all of the same traits, but sheds the glossy black design for a silver and white color option.

Samsung CF390

The CF390 features only VGA (D-Sub) and HDMI inputs while the CF591 overs VGA, dual HDMI and a single DisplayPort connection as well. Only the CF591 allows for audio input through a 3.5mm connection.

Samsung CF591

The supposed value of HDMI-based FreeSync is ubiquity and lower cost. Unfortunately, we don't have any pricing information from Samsung on either the CF390 or CF591 monitors, leaving a big question mark for AMD Radeon gamers that might be looking for a new display. Also, while the CF390 directly benefits from the addition of HDMI support on FreeSync, the CF591 still has a DisplayPort connection, meaning the value of HDMI-based FreeSync is lessened.

They 60Hz maximum refresh rate is disappointing in a world where 75Hz, 90Hz, even 165Hz monitors are being released left and right. Will the AMD driver-based frame doubling technology work on these displays? I have an inquiry in to AMD to verify but it might be difficult with the VA panels' minimum refresh rate. To be fair to AMD and Samsung though, this isn't marketed as a gaming monitor, just a monitor that happens to have a very gaming friendly option.

Both of these monitors look pretty sexy though; we need to see and test them in person to see if the image quality and FreeSync performance meet our expectations. Hopefully we'll be able to do so soon, but until then, let's hope that Samsung is able to release these at very competitive prices to help drive down the cost of VRR.

Video Perspective: Samsung Galaxy S7 / S7 Edge Hands-on from MWC 2016

MWC 16: Qualcomm talks antenna improvements in Galaxy S7

Subject: Mobile | February 23, 2016 - 08:14 AM |
Tagged: snapdragon 820, Samsung, s7, qualcomm, MWC 2016, MWC, galaxy

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.

antboost1.jpg

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.

upca.jpg

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.

Introduction, Specifications and Packaging

Introduction

Around this same time last year, Samsung launched their Portable SSD T1. This was a nifty little external SSD with some very good performance and capabilities. Despite its advantages and the cool factor of having a thin and light 1TB SSD barely noticeable in your pocket, there was some feedback from consumers that warranted a few tweaks to the design. There was also the need for a new line as Samsung was switching over their VNAND from 32 to 48 layer, enabling a higher capacity tier for this portable SSD. All of these changes were wrapped up into the new Samsung Portable SSD T3:

Specifications

T3 specs.png

Most of these specs are identical to the previous T1, with some notable exceptions. Consumer feedback prompted a newer / heavier metal housing, as the T1 (coming in at only 26 grams) was almost too light. With that newer housing came a slight enlarging of dimensions. We will do some side by side comparisons later in the review.

Read on for our full review of the new Samsung T3!
