Samsung Curved 1080p Monitors First with AMD FreeSync over HDMI

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.

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.

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 - 01:14 PM |

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.

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:

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.

MWC 16: Epic Games Unveils ProtoStar Demo on Galaxy S7

Mobile World Congress starts with a big bang... ... ... :3

Okay, not really; it starts with the formation of a star, which happens on a continual basis across the universe. I won't let facts get in the way of a pun, though.

As for the demo, it is powered by Unreal Engine 4 and runs on a Samsung Galaxy S7 with the Vulkan API. The setting seems to be some sort of futuristic laboratory that combines objects until it builds up into a star. It is bright and vibrant, with many particles, full-scene anti-aliasing, reflections, and other visual effects. The exact resolution when running on the phone was never stated, but the YouTube video was running at 1080p30, and the on-stage demo looked fairly high resolution, too.

Epic Games lists the features they added to mobile builds of Unreal Engine 4 for this demo:

  • Dynamic planar reflections
  • “Full” GPU particle support, which includes vector fields.
  • Temporal Anti-Alising, which blends neighboring frames to smooth jaggies in motion.
  • ASTC texture compression (created by ARM and AMD for OpenGL and OpenGL ES)
  • Full scene dynamic cascaded shadows
  • Chromatic aberration
  • Dynamic light refraction
  • Filmic tonemapping curve, which scales frames rendered in HDR to a presentable light range
  • Improved static reflections
  • High-quality depth of field
  • Vulkan API for thousands of onscreen, independent objects.

The company has not stated which version of Unreal Engine 4 will receive these updates. I doubt that it will land in 4.11, which is planned for March, but they tend to release a full dot-version every one to three months. They also have early previews for those who wish to try it early, some compiled leading up to launch, and others that need to be built from GitHub.

Samsung is showing off some very pretty displays

Subject: General Tech | February 17, 2016 - 05:53 PM |
Tagged: Samsung, transparent display, ML32E, TO55F

TechARP just posted a video of two reflective displays from Samsung, the 55" ML55E mirror display which has 55% reflectance and 90% transmittance and displays at 1920x1080 and a 32" model, the ML32E.  These will be used in store displays for now, but soon you may be upgrading your bathroom mirror so you can catch the news while you shave, or your Netflix stream while you take a quick break.

They also showed off the 55" O55F transparent OLED display, again 1080x1920 which is 45% transparent and they claim is able to provide 100% Adobe RGB colour space with 98% DCI color support.  As with the reflective displays you will first see these as store displays but it shouldn't be too long before we will be able to get our hands on them.  You can also see the Samsung PR here, unfortunately it does not specify what material was used in the transparent display but one hopes it is sturdy enough not to have to be protected from scratches and bumps.

Introduction

The steady increase in flash memory capacity per die is necessary for bringing SSD costs down, but SSDs need a minimum number of dies present to maintain good performance. Back when Samsung announced their 48-layer VNAND, their Senior VP of Marketing assured me that the performance drop that comes along with the low die count present in lower capacity models would be dealt with properly. At the time, Unsoo Kim mentioned the possibility of Samsung producing 128Gbit 48-layer VNAND, but it now appears that they have opted to put everything into 256Gbit on 3D side. Fortunately they still have a planar (2D) NAND production line going, and they will be using that same flash in a newer line of low capacity models. When their 850 Series transitions over to 48-layer (enabling 2TB capacities), Samsung will drop the 120GB capacity of that line and replace it with a new OEM / system builder destined 750 EVO:

160210-175142.jpg

The SSD 750 EVO Series is essentially a throwback to the 840 EVO, but without all of the growing pains experienced by that line. Samsung assured me that the same corrections that ultimately fixed the long-term read-based slow down issues with the 840 EVO also apply to the 750 EVO, and despite the model number being smaller, these should actually perform a bit better than their predecessor. Since it would be silly to just launch a single 120GB capacity to make up for the soon to be dropped 850 EVO 120GB, we also get a 250GB model, which should make for an interesting price point.

Specifications

Baseline specs are very similar to the older 840 EVO series, with some minor differences (to be shown below). There are some unlisted specs that are carried over from the original series. For those we need to reference the slides from the 840 EVO launch:

Samsung's HBM2 will be ready before you are

Subject: Memory | February 15, 2016 - 10:59 PM |
Tagged: Samsung, HBM2, Data Memory Systems

Samsung is ready to roll out the next generation of High Bandwidth Memory, aka HBM2, for your desktop and not just your next generation of GPU.  They have already begun production on 4GB HBM2 DRAM and promise 8GB DIMMs by the end of this year.  The modules will provide double the bandwidth of HBM1, up 256GB/s of bandwidth which is very impressive compared to the up to 70GB/s DDR4-3200 theoretically offers.

Not only is this technology going to appear in the next genertation of NVIDIA and AMD GPUs but could also work its way into main system memory.  Of course these DIMMs are not going to work with any desktop or mobile processor currently on the market but we will hopefully see new processors with compatible memory controllers in the near future.  You can also expect this to come with a cost, not just in expensive DIMMs at launch but also a comparible increaset in CPU prices as they will cost more to manufacture initially. 

It will be very interesting to see how this effects the overall market; will we see a split similar to what is currently seen in mainstream GPUs, a lower cost DDR version and a standard GDDR version?  The new market could see DDRx and HMBx models of CPUs and motherboards and could do the same for the GPU market, with the end of DDR on graphics cards.  If so will it spell the end of DDR5 development?  Interesting times to be living in, we should be hearing more from Samsung in the near future.
