CRYORIG's A40; two heads are better than one?

Subject: Cases and Cooling | July 21, 2017 - 03:49 PM |
Tagged: CRYORIG, CRYORIG A40, AIO, water cooler

The CRYORIG A40 is not a new cooler but its unique design is worth revisiting for those who have forgotten about its existence.  Instead of having a single area in which to dump heat, the pump assembly mounted to the CPU also has its own fan.  That fan did not not noticeably decrease the CPU temperatures when TechPowerUp tested it, however for SFF systems and other builds with components which could benefit from airflow inside the case that fan is more than just a gimmick.  Check out the full review here.

"The A40 by CRYORIG is the company's entry level offering in their all-in-one hybrid liquid CPU cooler lineup. It lacks the size of the A80 and the radiator thickness of the A40 Ultimate. However, unlike the others, it offers a more affordable price point with all the same features."

Overview

A few months ago at Computex, NVIDIA announced their "GeForce GTX with Max-Q Design" initiative. Essentially, the heart of this program is the use of specifically binned GTX 1080, 1070 and 1060 GPUs. These GPUs have been tested and selected during the manufacturing process to ensure lower power draw at the same performance levels when compared to the GPUs used in more traditional form factors like desktop graphics cards.

In order to gain access to these "Max-Q" binned GPUs, notebook manufacturers have to meet specific NVIDIA guidelines on noise levels at thermal load (sub-40 dbA). To be clear, NVIDIA doesn't seem to be offering reference notebook designs (as demonstrated by the variability in design across the Max-Q notebooks) to partners, but rather ideas on how they can accomplish the given goals.

At the show, NVIDIA and some of their partners showed off several Max-Q notebooks. We hope to take a look at all of these machines in the coming weeks, but today we're focusing on one of the first, the ASUS ROG Zephyrus.

As you can see, the ASUS ROG Zephyrus has the specifications of a high-end gaming desktop, let alone a gaming notebook. In some gaming notebook designs, the bottleneck comes down to CPU horsepower more than GPU horsepower. That doesn't seem to be the case here. The powerful GTX 1080 GPU is paired with a quad-core HyperThread Intel processor capable of boosting up to 3.8 GHz.

Devil's Ivy, a voyeurs dream come true

Subject: General Tech | July 20, 2017 - 03:50 PM |
Tagged: iot, Devil's Ivy, cameras, security, gSOAP

gSOAP is a open-source code library which allows hardware to be configured and controlled via web connections and is used by hundreds of companies including Axis, Microsoft, IBM, Adobe and Xerox.  It has a vulnerability which allows an attacker to trigger a stack overflow by sending a specific POST command over port 80 to a device, which in the case of cameras allows you to watch the live feed.  The vulnerability was patched in an update to gSOAP so future products will not have this issue, however any camera built on that library which currently in use is vulnerable.  The manufacturers would have to create an update to their own software and push it out to all the cameras currently in use to resolve this issue, and if there is one thing we know for sure about IoT products, it is that these patches do not tend to be created, let alone pushed out.

A new BioStar has Ryzen, the Racing X370GT7

Tagged: x370, ryzen, Racing X370GT7, biostar, amd, AM4

BioStar have greeted the release of AMD's Ryzen with enthusiasm, releasing numerous AM4 boards, some of which are garnering better reviews than the main brands.  [H]ard|OCP tested out their Racing X370GT7, an ATX model with a ~$160 price tag.  The silkscreen on the board is rather unique and the layout is extremely clean.  You get a lot of nice high end features such as a heatsink for the M.2 slot located just below the CPU socket, Realtec ALC1220 8 channel audio and even an LN2 switch for extreme overclockers.  As with many other X370 boards there were some quirks with memory compatibility as well as some questionable UEFI choices specific to this board.  It will offer a solid base for someone building a Ryzen platform and it will likely improve as the AMD Generic Encapsulated Software Architecture for AM4's matures.

"BIOSTAR isn’t exactly a juggernaut of a manufacturer here in the U.S. Despite stiff competition, the big boys are blowing it bad enough at the X370 Ryzen motherboard game that BIOSTAR’s X370GT7 just might be one of the best AM4 motherboard options around. While we think it might actually be good, it still doesn’t make for a smooth ride."

It's dangerous to go alone; gaming on a Lenovo X1 Carbon ultrabook

Subject: General Tech | July 19, 2017 - 03:01 PM |
Tagged: gaming, ultrabook, Lenovo, ThinkPad X1 Carbon

Techspot recently investigated the ability of current generation ultrabooks to game, without external assistance.  They tested using a Lenovo X1 Carbon, similar to what Ken utilized when he benchmarked the AKiTiO Node external GPU.  Techspot's model had a Core i5-7200U as opposed to the 7300U both chips have the same HD 620 iGPU, but only Ken's had help. 

Techspot focused on the performance the ultrabook could provide in 34 different games, from current and past AAA games as well as eSports and even 2D indie games.  Take a look through their results to see just how far we have come since the original generations of Intel iGPUs which simply could not game at all.  The results show that there is indeed a market for Thunderbolt based external GPUs.

You've got to go deep before you can be extreme, TSMC is moving to 7nm

Subject: General Tech | July 19, 2017 - 12:41 PM |
Tagged: TSMC, 7nm, duv, N7, euv

TSMC is preparing for the move to a 7nm process by expanding suppliers and tooling up for Deep UV equipment.  Unlike Samsung, who will be using Extreme UV tools for their initial launch of 7nm product in 2018 TSMC have chosen to delay the move to EUV until the technology matures.  They will instead use DUV for its launch of their 7nm products, dubbed 7N, in 2018.  The difference between the two types of UV is the wavelength, DUV can be produced at 248 and 193 nm while EUV is an impressive 13.5nm, which is why the industry (and ourselves) depend on this process maturing and being adopted by manufacturers.  The EUV equipment that is being tested is still relatively new but should produce a better chip in theory, though perhaps not as many usable ones per wafer when first rolled out.  You can pop by DigiTimes for a list of the suppliers TSMC is adopting as well as a bit more detail.

Intelligent Gaming

Kal Simpson recently had the chance to sit down and have an extensive interview with SILVIA's Chief Product Officer - Cognitive Code, Alex Mayberry.  SILVIA is a company that specializes on conversational AI that can be adapted to a variety of platforms and applications.  Kal's comments are in bold while Alex's are in italics.

SILVIA virtual assistant.jpg

Always good to speak with you Alex. Whether it's the latest Triple-A video game release or the progress being made in changing the way we play, virtual reality for instance – your views and developments within the gaming space as a whole remains impressive. Before we begin, I’d like to give the audience a brief flashback of your career history. Prominent within the video game industry you’ve been involved with many, many titles – primarily within the PC gaming space. Quake 2: The Reckoning, America’s Army, a plethora of World of Warcraft titles.

Those more familiar with your work know you as the lead game producer for Diablo 3 / Reaper of Souls, as well as the executive producer for Star Citizen. The former of which we spoke on during the release of the game for PC, PlayStation 4 and the Xbox One, back in 2014.

So I ask, given your huge involvement with some of the most popular titles, what sparked your interest within the development of intelligent computing platforms? No-doubt the technology can be adapted to applications within gaming, but what’s the initial factor that drove you to Cognitive Code – the SILVIA technology?

AM: Conversational intelligence was something that I had never even thought about in terms of game development. My experience arguing with my Xbox and trying to get it to change my television channel left me pretty sceptical about the technology. But after leaving Star Citizen, my paths crossed with Leslie Spring, the CEO and Founder of Cognitive Code, and the creator of the SILVIA platform. Initially, Leslie was helping me out with some engineering work on VR projects I was spinning up. After collaborating for a bit, he introduced me to his AI, and I became intrigued by it. Although I was still very focused on VR at the time, my mind kept drifting to SILVIA.

I kept pestering Leslie with questions about the technology, and he continued to share some of the things that it could do. It was when I saw one of his game engine demos showing off a sci-fi world with freely conversant robots that the light went on in my head, and I suddenly got way more interested in artificial intelligence. At the same time, I was discovering challenges in VR that needed solutions. Not having a keyboard in VR creates an obstacle for capturing user input, and floating text in your field of view is really detrimental to the immersion of the experience. Also, when you have life-size characters in VR, you naturally want to speak to them. This is when I got interested in using SILVIA to introduce an entirely new mechanic to gaming and interactive entertainment. No more do we have to rely on conversation trees and scripted responses.

how-silvia-work1.jpg

No more do we have to read a wall of text from a quest giver. With this technology, we can have a realistic and free-form conversation with our game characters, and speak to them as if they are alive. This is such a powerful tool for interactive storytelling, and it will allow us to breathe life into virtual characters in a way that’s never before been possible. Seeing the opportunity in front of me, I joined up with Cognitive Code and have spent the last 18 months exploring how to design conversationally intelligent avatars. And I’ve been having a blast doing it.

Rumor: Corsair Could Be Purchased for >$500 Million USD

Subject: General Tech | July 19, 2017 - 07:01 AM |
Tagged: corsair

According to Reuters, who claims to have two anonymous sources, Corsair “is in advanced discussions” to be acquired by EagleTree Capital. They claim that the transaction, if it goes through in its current form, will be worth more than $500 million USD. EagleTree has several backers, including Goldman Sachs, Macquarie Group, and BNP Paribas.

corsair-2017-logo.png

From my perspective, this would be an interesting transaction. The company, being private, hasn’t published their finances recently, but annual revenue was as high as $455 million in 2011. Their catalog has since diversified heavily, especially with their seemingly successful power supply, case, and liquid cooling product lines. At first, the rumor felt a little high, because half-of-a-billion dollars is a lot of money, but they’re certainly selling a lot of stock. At the same time, they don't do a lot of their own production, but they do spend a lot of effort in their designs and making them fit a unique niche in one way or another.

Thanks to TechSpot for noticing this!

It has been a few months since Al looked at Intel's Optane and its impressive performance and price.  This is why it seems appropriate to revist the 2280 M.2 stick with a PCIe 3.0 x2 interface.  It is not just the performance which is interesting but the technology behind Optane and the limitations.  For anyone looking to utilize Optane is is worth reminding you of the compatibility limitations Intel requires, only Kaby Lake processors with Core i7, i5 or i3 heritage.  If you do qualify already or are planning a system build, you can revisit the performance numbers over at Kitguru.

"Optane is Intel’s brand name for their 3D XPoint memory technology. The first Optane product to break cover was the Optane PC P4800X, a very high-performance SSD aimed at the Enterprise segment. Now we have the second product using the technology, this time aimed at the consumer market segment – the Intel Optane Memory module."

As with the previous model, HyperX has chosen a metal body for the Alloy Elite.  This one is larger than that model, at 17.5" x 6.6" which leaves space for a light bar containing 18 red LEDs as well as media keys.  HyperX offers you the choice between MX Blue, Brown, or Red switches, optional silvery WASD keycaps and a removable wrist rest.  The Tech Report had a good experience with the keyboard, however if you consider custom macros, profiles, and lighting features to be critical then perhaps this board is not for you.

Google Glass is back, but this time the users should be safely contained in manufacturing facilities and corporate buildings.  The initial launch lead to what many felt was a breach of public etiquette as there were many people who did not like the idea of being recorded with the AR glasses.  The new incarnation, Glass Enterprise Edition has an improved 8MP camera and a new red light that turns on when the glasses are recording video.  The WiFi bandwidth has been increased but Alphabet has not yet released the technical specifications publicly.  The Inquirer has a bit more information but nothing on the price, you will need to negotiate with Alphabet or one of it's partners to find that out, but you can expect it to be similar to the price of Microsoft's HoloLens.

With the latest revision of the TUF line, ASUS made the decision to drop the well-known "Sabertooth" moniker from the board's name, naming the board with the TUF branding only. The TUF Z270 Mark 1 motherboard is the flagship board in ASUS' TUF (The Ultimate Force) product line designed with the Intel Z270 chipset. The board offers support for the latest Intel Kaby Lake processor line as well as Dual Channel DDR 4 memory because of its integrated Intel Z270 chipset. While the MSRP for the board may be a bit higher than expected, its $239 price is more than justified by the board's build quality and "armored" offerings.

The TUF Z270 Mark 1 motherboard is built with the same quality and attention to detail that you've come to expect from TUF-branded motherboards. Its appearance follows the standard tan plastic armor overlay on the top with a 10-phase digital power system. ASUS also chose to include the armored backplate with the TUF Z270 Mark 1 motherboard, dubbed the "TUF Fortifier". The board contains the following integrated features: six SATA 3 ports; two M.2 PCIe x4 capable ports; dual GigE controllers - an Intel I219-V Gigabit NIC and an Intel I211 Gigabit NIC; three PCI-Express x16 slots; three PCI-Express x1 slots; an 8-channel audio subsystem; MEM OK! and USB BIOS Flashback buttons; integrated DisplayPort and HDMI; and USB 2.0, 3.0, and 3.1 Type-A and Type-C port support.

Rumor: Intel to Launch Quad Core Kaby Lake-R CPUs for Ultraportables

Subject: Processors, Mobile | July 17, 2017 - 04:32 PM |
Tagged: ultrabook, quad core, Intel, i5-8520u, i5-7200u, hyperthreading, dell xps 13, acer swift 3, 15w

A few days ago, laptopmedia.com uncovered some listings for an unannounced revision to the Acer Swift 3 notebook.

swift-3.jpg

In addition to the new Pascal-based NVIDIA MX150 GPU announced just before Computex, astute readers will also spot an unannounced CPU from Intel – the Core i5-8250U. While the model number itself doesn't tell us much other than it's a next generation CPU, the description in the Acer product listings notes it as a quad core CPU.

Following Intel's history with the U-series parts, the 8250U would traditionally be a 15W, dual core CPU with hyperthreading enabled, with the true quad core parts starting with the 35W TDP options

We've had an indication that a quad core U-series processor was coming in the second half of this year from Intel's performance claims presented at Computex this year, but we weren't quite sure what form it would take.

Doing some additional research, we can see several results from this processor in the Geekbench database from various notebook manufacturers – including devices we would expect to be refreshed like the Dell XPS 13 and ASUS Zenbook UX490.

8250u-geekbench.png

From the Geekbench results of the XPS 13 with the i5-8520U compared to the current generation i5-7200U, we see a 54% increase in multi threaded CPU performance while only a 7% increase in single threaded performance. Keep in mind that these leaked benchmarks should be taken with a grain of salt, but we would be very impressed with these numbers in a shipping notebook.

Geekbench's processor profiler also reveals the i5-8250U to be a 4 core/8 thread processor, pointing to hyperthreading being enabled on the i5 processors as well as the i7's, like we currently see in the U-series.

kaby-lake-r.jpg

Some people have been theorizing that this 8000 series processor is from the upcoming Coffee Lake release. However, based on some of the Intel roadmap leaks from late last year, I think that this is actually a Kaby Lake-R CPU. The leaked roadmap suggests that Kaby Lake-R will launch as the 8th generation processor family, to be released in the second half of 2017.

Either way, I am excited to finally see some push forward in the 15W CPU space, which I consider to be the sweet spot between battery life and performance for most users.

Stay tuned for more information on these new Intel processors and these new notebooks as we get out hands on them!

Specifications and Design

Just a couple of short weeks ago we looked at the Radeon Vega Frontier Edition 16GB graphics card in its air-cooled variety. The results were interesting – gaming performance proved to fall somewhere between the GTX 1070 and the GTX 1080 from NVIDIA’s current generation of GeForce products. That is under many of the estimates from players in the market, including media, fans, and enthusiasts.  But before we get to the RX Vega product family that is targeted at gamers, AMD has another data point for us to look at with a water-cooled version of Vega Frontier Edition. At a $1500 MSRP, which we shelled out ourselves, we are very interested to see how it changes the face of performance for the Vega GPU and architecture.

Let’s start with a look at the specifications of this version of the Vega Frontier Edition, which will be…familiar.

The base specs remain unchanged and AMD lists the same memory frequency and even GPU clock rates across both models. In practice though, the liquid cooled version runs at higher sustained clocks and can overclock a bit easier as well (more details later). What does change with the liquid cooled version is a usable BIOS switch on top of the card that allows you to move between two distinct power draw states: 300 watts and 350 watts.

IMG_4728.JPG

First, it’s worth noting this is a change from the “375 watt” TDP that this card was listed at during the launch and announcement. AMD was touting a 300-watt and 375-watt version of Frontier Edition, but it appears the company backed off a bit on that, erring on the side of caution to avoid breaking any of the specifcations of PCI Express (board slot or auxiliary connectors). Even more concerning is that AMD chose to have the default state of the switch on the Vega FE Liquid card at 300 watts rather than the more aggressive 350 watts. AMD claims this to avoid any problems with lower quality power supplies that may struggle to hit slightly over 150 watts of power draw (and resulting current) from the 8-pin power connections. I would argue that any system that is going to install a $1500 graphics card can and should be prepared to provide the necessary power, but for the professional market, AMD leans towards caution. (It’s worth pointing out the RX 480 power issues that may have prompted this internal decision making were more problematic because they impacted the power delivery through the motherboard, while the 6- and 8-pin connectors are generally much safer to exceed the ratings.)

Even without clock speed changes, the move to water cooling should result in better and more consistent performance by removing the overheating concerns that surrounded our first Radeon Vega Frontier Edition review. But let’s dive into the card itself and see how the design process created a unique liquid cooled solution.

Counting Cores ... Intel on the Bench

There is a $50 difference in price between these two chips, $390 versus $340, which will be within the price range of many of enthusiasts.  The i7-7700K's cores run at a higher frequency but there are only four whereas the i7-7800X has a half dozen.  The memory configuration is also a factor, with the Skylake chip offering quad channel memory while the Kaby Lake only offers dual channel.  The size of the cache may not have a huge impact on gaming performance but you need to consider the number of PCIe lanes; is 16 sufficient or will you need 28?

Techspot seeks to answer this question with a large number of gaming benchmarks, including PlayerUnknown's Battlegrounds.

"Although we consider the Ryzen 5 1600 to be the sweet spot for building a new high-end gaming rig, many of you interested in going Intel want to know whether it makes more sense to buy the Core i7-7700K or the new 7800X?"

Thermaltake's $25 Contac Silent 12 heatsink for Ryzen

Thermaltake has a new cooler for those planning a Ryzen build on a budget, or for quiet system builds.  The Contac Silent 12 is a mere 153x12x100.3mm in size, with the fan attached, and weighs a paltry 700g however it is capable of almost matching the performance of AMD's Wraith cooler while operating at a noticeably quieter level.  In addition to the heatsink you will find a 'low-noise cable' which changes the fans RPM span from 500-1500 RPM to 400-1100 RPM however in their tests The Tech Report found it had little effect on the noise produced by a system under load.  See the full results here.

"Thermaltake's Contac Silent 12 relies on an established design and a simple mounting system to get AMD Socket AM4 builders up and running as quickly as possible. We tested this cooler at stock and overclocked speeds to see how it stacks up for just $25."
