Ansel arrives and NVIDIA holds a celebration in their VR Funhouse

Subject: General Tech | July 14, 2016 - 06:06 PM |
Tagged: nvidia, vr funhouse, ansel, vrworks

A while back Scott wrote about NVIDIA's Ansel, a screenshot application on performance enhancing drugs.  Today it arrives, paired with their new driver and adds support for Mirror's Edge Catalyst to the list of supported games such as The Witcher 3: Wild Hunt, Unreal Tournament, Tom Clancy’s The Division, and No Man’s Sky just to name a few.  The tool allows you to take 360 degree screen captures, allowing you to completely rotate around the image on a 2D screen or with VR headsets like the Vive or Rift.  Just trigger the recording while you are in game, the game will pause and you can roll, zoom, and position your focus to get the screenshot you want.  From there hit the Super Resolution button and your screenshot will be of significantly greater quality than the game ever could be.  The thumbnail below is available in its original 46080x25920 resolution by visting NVIDIA's Ansel page, it is a mere 1.7GB in size.

NVIDIA also released their first game today, a VR Funhouse available on Steam for no charge ... apart from the HTC Vive and minimum hardware requirements of an GTX 1060 and i7 4790 or the recommended GTX 1080 and i7 5930, which are enough of an investment as it is.  There are seven games to play, expect skeet shooting, whack a mole and other standard carny games.  At the same time it is a showcase of NVIDIA's VR technology, not just the *Works which we are familiar with but also VR SLI support for those with multiple GPUs and VRWorks Multi-res Shading which reduces processing load by only rendering full detail to objects within your field of view.  If you have the hardware you should check out the game, it is certanly worth the admission price.

Has the almost obscene lack of security in automobile software made you somewhat paranoid, even if you trust the Tesla autopilot?  Has the fact that a mere attempt to access your cars software could land you in jail turned you completely off of buying a car less than 10 years old?

How would you feel about a version of Linux controlling some of the features of your car?  That is exactly what the Linux Foundation is working on with the AGL project.  The hardware used will include DragonBoard, Wandboard, and Raspberry Pi and automobile manufacturers joining the project include  Ford, Subaru, Mazda, Mitsubishi, Toyota, Nissan, and Jaguar Land Rover.  So far the project only encompasses in-car entertainment but it does have the potential to grow beyond that.  Check out the story on Linux.com for more.

Through the looking glass

Futuremark has been the most consistent and most utilized benchmark company for PCs for quite a long time. While other companies have faltered and faded, Futuremark continues to push forward with new benchmarks and capabilities in an attempt to maintain a modern way to compare performance across platforms with standardized tests.

Back in March of 2015, 3DMark added support for an API Overhead test to help gamers and editors understand the performance advantages of Mantle and DirectX 12 compared to existing APIs. Though the results were purely “peak theoretical” numbers, the data helped showcase to consumers and developers what low levels APIs brought to the table.

3dmark-time-spy-screenshot-2.jpg

Today Futuremark is releasing a new benchmark that focuses on DX12 gaming. No longer just a feature test, Time Spy is a fully baked benchmark with its own rendering engine and scenarios for evaluating the performance of graphics cards and platforms. It requires Windows 10 and a DX12-capable graphics card, and includes two different graphics tests and a CPU test. Oh, and of course, there is a stunningly gorgeous demo mode to go along with it.

I’m not going to spend much time here dissecting the benchmark itself, but it does make sense to have an idea of what kind of technologies are built into the game engine and tests. The engine is based purely on DX12, and integrates technologies like asynchronous compute, explicit multi-adapter and multi-threaded workloads. These are highly topical ideas and will be the focus of my testing today.

Futuremark provides an interesting diagram to demonstrate the advantages DX12 has over DX11. Below you will find a listing of the average number of vertices, triangles, patches and shader calls in 3DMark Fire Strike compared with 3DMark Time Spy.

daigram.png

It’s not even close here – the new Time Spy engine has more than a factor of 10 more processing calls for some of these items. As Futuremark states, however, this kind of capability isn’t free.

With DirectX 12, developers can significantly improve the multi-thread scaling and hardware utilization of their titles. But it requires a considerable amount of graphics expertise and memory-level programming skill. The programming investment is significant and must be considered from the start of a project.

Dell's New 30" 4K 120Hz UP3017Q OLED Monitor Coming Soon

Subject: Displays | July 14, 2016 - 12:43 PM |
Tagged: USB 3 Type-C, up3017q, oled, DisplayPort, Dell 4K, dell, 4K 120

Initially teased at CES earlier this year, Dell’s UP3017Q is an amazing 30-inch 4K monitor with an OLED panel capable of running at 120Hz. The thin bezeled UltraSharp is also extremely thin at less than 0.5” at the edges. Running a resolution of 3840 x 2160, the 30” monitor comes in at 146 PPI (pixels per inch). The UP3017Q was originally slated for a March release, but it ended up not being available. Reportedly, Dell is still fine tuning the monitor and it will be available soon though the company has not given a new specific launch date when you will actually be able to buy it.

It has some rather impressive specifications, and I am really interested in seeing it in person! The panel manufacturer is still unknown (though many have guessed it is one from LG), but it offers up a resolution of 3840 x 2160, refresh rate of up to 120Hz, 0.1ms response time, and 400,000:1 contrast ratio. Being OLED (Organic Light Emitting Diode), the monitor will be able to deliver true blacks and excellent colors in a very thin profile thanks to not needing a separate backlight (the pixels themselves emit light). Dell claims that the UP3017Q 4K monitor fully supports 100% of the Adobe RGB and 97.8% DCI-P3 color spaces. At a claimed 1.07 billion colors this is a 10-bit color monitor which will be useful in professional applications where color accuracy is paramount.

Dell has further claimed that it has mitigated burn in on this monitor by implementing a “pixel shifting algorithm” as well as placing a sensor on the monitor that can detect when you are looking at it and turn off when no one is watching anything on it (which some might find a bit creepy but it can likely be turned off heh). There are five buttons on this monitor, four on the bottom edge for OSD controls and one on the back to release the monitor from its stand.

Dell UP3017Q.jpg

One interesting hang up lies in the video inputs on this monitor. It only has HDMI 2.0, Mini DisplayPort 1.2, and USB Type-C. As posters over at [H] pointed out, the HDMI 2.0 and DP 1.2 connections do not have enough bandwidth to support the panels 3840 x 2160 resolution at 120Hz. Fortunately the refresh rate is not a lie. There is a a way to do it, but users will need to use the USB Type-C connector and it’s DisplayPort Alternate Mode feature to do it. At DisplayPort 1.2, the DisplayPort Alt Mode can give you 5.4 Gbps per lanes and using all four available lanes can hit a total of 21.6 Gbps which would be enough to support 4096x2160@60Hz. However, the DisplayPort 1.3 standard (which this monitor and it’s USB Type-C port seems to support) can give up to 8.1 Gbps for up to 32.4 Gbps of bandwidth (25.92 Gbps after 8b/10b encoding overhead) which should allow the full 3840x2160@120Hz to be used. It is unfortunate that Dell opted to go with this odd port arrangement and not include a direct DP 1.3+ port though!

This monitor has a lot of potential, but this massive OLED comes at a price: when it comes to market it will have a MSRP of $4,999! As much as many would want this to be their new gaming PC monitor, I think it will be mainly for commercial and design applications especially with the input lag being unknown and no support for the various variable refresh rate technologies (AMD FreeSync and NVIDIA G-Sync) If that is what you are looking for there are much cheaper options, but if you want an all out OLED monitor for work and media and price is no object I would be very eagerly waiting for reviews on this!

What are your thoughts on this monitor and OLED?

DOOM on Vulkan Benchmarks

Subject: Graphics Cards | July 13, 2016 - 09:20 PM |
Tagged: vulkan, R9 Fury X, nvidia, Mantle, gtx 1070, fury x, doom, amd

We haven't yet benchmarked DOOM on Vulkan Update (immediately after posting): Ryan has just informed me that, apparently, we did benchmark Vulkan on our YouTube page (embed below). I knew we were working on it, I just didn't realize we published content yet. Original post continues below.

As far as I know, we're trying to get our testing software for frame time analysis running on the new API, but other sites have posted framerate-based results. The results show that AMD's cards benefit greatly from the new, Mantle-derived interface (versus the OpenGL one). On the other hand, while NVIDIA never really sees a decrease, more than 1% at least, it doesn't really get much of a boost, either.

I tweeted out to ID's lead renderer programmer, Tiago Sousa, to ask whether they take advantage of NVIDIA-specific extensions on the OpenGL path (like command submission queues). I haven't got a response yet, so it's difficult to tell whether this speaks more toward NVIDIA's OpenGL performance, or AMD's Vulkan performance. In the end, it doesn't really matter, though. AMD's Fury X (which can be found for as low as $399 with a mail-in rebate) is beating the GTX 1070 (which is in stock for the low $400s) by a fair margin. The Fury X also beats its own OpenGL performance by up to 66% (at 1080p) with the new API.

The API should also make it easier for games to pace their frames, too, which should allow smoother animation at these higher rates. That said, we don't know for sure because we can't test that from just seeing FPS numbers. The gains are impressive from AMD, though.

Asynchronous Atomic Ghandi coming in Civ VI

Tagged: gaming, dx12, civilization VI, asynchronous compute, amd

AMD, 2K and Firaxis Games have been working together to bring the newest DX12 features to Civilization IV and today they have announced their success.  The new game will incorporate Asynchronous Compute in the engine as well as support for Explicit Multi-Adapter for those with multiple GPUs.  This should give AMD cards a significant performance boost when running the game, at least until NVIDIA can catch up with their support for the new technologies ... HairWorks is not going to have much as effect on your units as Async Compute will.

If you haven't been keeping an eye out, we have seen the video of Egypt's leader which also talk about terrain adjacency bonuses and England's leader and civilization specific units and buildings.

"Complete with support for advanced DirectX 12 features like asynchronous compute and explicit multi-adapter, PC gamers the world over will be treated to a high-performance and highly-parallelized game engine perfectly suited to sprawling, complex civilizations."

CryptoDrop, an early warning system against ransomeware

Subject: General Tech | July 13, 2016 - 01:29 PM |
Tagged: ransomware, CryptoDrop

Given the choice between a confirmation pop up every time you zip numerous files simultaneously or add encryption to a folder or being infected with ransomware; which would you choose?  Researchers at the University of Florida and Villanova University have developed software called CryptoLock which scans your systems for bulk modification of file types, a significant change in the contents of those files and an increase in the Shannon Entropy of the files.  All three of those indicate a file is being encrypted and if it is happening to numerous ones in a very short period of time then the software will put a halt to it until you confirm that this is expected behaviour.  You get a quick overview over at The Register as well as a link to the PDF of the researchers work.

Sounds like a pop up we can live with, considering the alternative.  Hopefully this will arrive on the market soon.

"Taking a “save what you can” approach, the authors of this PDF reckon in their tests they were able to lower the boom on ransomware when it had encrypted just 0.2 per cent of files on their test setup."

Thought that Microsoft did a poor job on the consumer side of Windows 10, you haven't being watching the absurdity which is the Enterprise version.  They took putting the cart in front of the horse to new levels but as of today we finally have a monthly price for a user.  This announcement comes several months after they removed the ability of system admins to block installation of random apps from the Windows Store for those using Windows 10 Professional.  It is also a week after they announced the removal of two popular components of the Microsoft Desktop Optimisation Pack, App-V and UE-V. 

Today we have received word that the Windows 10 Enterprise E3 version will be $7 per user per month, though we have yet to hear any pricing on the E5 version which includes Windows Defender Advanced Threat Protection.  You can read more at Slashdot while you laugh about Microsoft's apparent confusion as to why businesses are not yet willing to adopt their new OS.

Introduction, Specifications, and Packaging

Introduction:

Everyone expects SSD makers to keep pushing out higher and higher capacity SSDs, but the thing holding them back is sufficient market demand for that capacity. With that, it appears Samsung has decided it was high time for a 4TB model of their 850 EVO. Today we will be looking at this huge capacity point, and paying close attention to any performance dips that sometimes result in pushing a given SSD controller / architecture to extreme capacities.

DSC01499.jpg

This new 4TB model benefits from the higher density of Samsung’s 48-layer V-NAND. We performed a side-by-side comparison of 32 and 48 layer products back in March, and found the newer flash to reduce Latency Percentile profiles closer to MLC-equipped Pro model than the 32-layer (TLC) EVO:

"When powered, the magnetic levitation bearing completely suspends the fan blades from the motor housing, delivering almost frictionless operation. The huge reduction in friction, in comparison to all conventional physical contact bearings, allows the ML Series to offer lower noise at higher RPMs giving PC Enthusiasts a true no-compromise fan."

Corsair will offer 10 variants of this new ML Series, with 120 and 140 mm versions in different colors, as well as RGB options (of course!).

"ML Series also provides next-level fan customization. ML PRO fans feature removable color co-coordinated corners fitted to the fan’s vibration dampening rubber grommets, allowing easy color matching to accent your build’s color scheme. ML PRO LED goes even further, mounting four ultra-bright LEDs into the central fan hub to radiate vibrant, even lighting through the fan’s frosted blades."

As to performance, Corsair offers this information from their press release:

"All ML fans offer a huge PWM range, giving users total control over how their fans perform. Value silence above all else? At their lowest speed of 400 RPM, the ML Series will push more airflow at near silent 16 dBA (decibel A-weighting). Performance junkie? ML Series fans push up to 97 CFM (cubic feet per minute) of air. Be it a low noise case, high density radiator or anywhere in-between, the ML Series delivers best-in-class performance."

Corsair provides this video for the launch of the ML Series:

The fans are available immediately, and prices start at $24.99 for a single ML120 Pro fan, with 2-packs of the standard version starting at $34.99

Asus Teases Its Custom RX 480 STRIX Graphics Card

Subject: Graphics Cards | July 12, 2016 - 12:01 AM |
Tagged: strix, rx 480, Radeon RX 480, polaris 10, asus, amd

Alongside the launch of AMD’s reference design Radeon RX 480, the company’s various AIB (Add-In Board) partners began announcing their own custom versions pairing AMD’s Polaris 10 GPU with custom PCBs and coolers. Asus took the launch to heart and teased its Radeon RX 480 STRIX under it’s ROG lineup. The press release was rather scant with details, but it does look like a promising card that will let users really push Polaris 10 to it’s limits.

ASUS ROG STRIX RX 480 Graphics Card.png

Thanks to forum user Eroticus over at VideoCardz, the RX 480 STRIX looks to use a custom PCB and power delivery design that feeds the GPU via two PCI-E power connectors in addition to the PCI-E slot. Asus is not talking clock speeds on the GPU, but they did reveal that they are going with 8GB of GDDR5 memory at 8 GHz. The DirectCU III cooler pairs heatpipes and an aluminum fin stack with three shrouded fans. There is also a backplate (of course, with a LED backlit logo) which should help support the card and provide a bit more cooling.

I would not expect too much of a factory (out of the box) overclock from this card. However, I do expect that users will be able to seriously overclock the Polaris 10 GPU thanks to the extra power connector (allegedly one 6-pin and one 8-pin which seems a bit much but we’ll see!) and beefy air cooler.

For reference, the, well, reference design RX 480 has base and boost clock speeds of 1120 MHz and 1266 MHz respectively. The Polaris 10 GPU has 2,304 cores, 144 texture units, and 32 raster operators. If buyers get a good chip in their RX 480 Strix, it may be possible for them to get to 1400 MHz boost as some of the rumors around the Internet claim though it’s hard to say for sure as that may require quite a bit more voltage (and heat) to reach. I wouldn’t put it out of the realm of possibility though!

Of course it would not be Republic of Gamers’ material without LEDs, and ASUS delivers with the inclusion of its Aura RGB LEDs on the cooler shroud and backplate which I believe are user configurable in Asus’ software utility.

Beyond that, not much is known about the upcoming RX 480 STRIX graphics card. Stay tuned to PC Perspective for more information as it gets closer to availability!

Palit's triple wide GTX 1080 GameRock Premium

Tagged: GTX 1080, GameRock Premium, palit, factory overclocked

Palit's card is certainly unique looking in the GTX 1080 market, that blue, white and silver is not a colour palette used by other manufacturers.  That is not the only difference between this card and a stock GTX 1080, it is also overclocked with a core of 1746 MHz and VRAM at 1315 MHz, along with a cooler that covers the entire card and takes up three slots.  That extra cooling ability translates into a card that runs at 30dBA under load, and TechPowerUp did not see temperatures exceeding 72°C.  It is a little on the expensive side but if you have space in your case this is a worth contender for your hard earned cash.

card1.jpg

"Palit's GTX 1080 GameRock uses a mighty triple-slot dual-fan design, which provides excellent temperatures and noise levels better than any GTX 1080 we tested so far. The fans also turn off in idle, and thanks to the large overclock out the box, the card is the fastest GTX 1080 we ever tested, too."

DOOM comes to Vulkan; or vice versa

Subject: General Tech | July 11, 2016 - 12:16 PM |
Tagged: vulkan, doom, bethesda

*** Update *** an asute reader spotted some quick and dirty benchmarks over at Guru of 3D.  It looks like the RX480 does indeed benefit from Vulkan, the GTX 1070 not so much.

While this does not mean that the new DOOM will run on Linux, today does see Vulkan support arriving for the new FPS.  As we have seen with titles such as BF4 this is not going to benefit users of high end GPUs in any great way, however gamers on a budget should see improvements.  Bethesda did not update their minimum specs but do anticipate older cards being able to maintain more respectable framerates; the current minimum specs are a GTX 670 or HD 7870.  Expect to see some bugs as this their first shot at the Vulkan API, but do check it out if you have a lower end card or are simply curious how well it works. Handy links for drivers and more info over at Bethesda.

"At id Software, we’ve always pushed technology. With DOOM we let the game drive the technology decisions from early on. This has continued even in post-release, with new updates and more. Today we’re excited to share another big technology push: Vulkan support is now live on PC."

Qualcomm Announces the Snapdragon 821 SoC

Subject: Processors, Mobile | July 11, 2016 - 11:44 AM |
Tagged: SoC, Snapdragon 821, snapdragon, qualcomm, adreno 530

Announced today, the Snapdragon 821 offers a modest CPU frequency increase over the Snapdragon 820, with clock speeds of up to 2.4 GHz compared to 2.2 GHz with the Snapdragon 820. The new SoC is still implementing Qualcomm's custom quad-core "Kryo" design, which is made up of two pairs of dual-core CPU clusters.

Screenshot_20160711-112828~2.png

Quoting Anandtech, who also reported on the Snapdragon 821 today:

"What isn’t in this announcement is that the power cluster will likely be above 2 GHz and GPU clocks look to be around 650 MHz but without knowing whether there are some changes other than clock relative to Adreno 530 we can’t really estimate the performance of this part."

Specifics on the Adreno GPU were not mentioned in the official announcement. The 650 MHz GPU clock reported by Anandtech would offer a modest improvement over the SD820's 624 MHz Adreno 530 GPU. Additionally, the "power cluster" will reportedly move from 1.6 GHz with the SD820 to 2.0 GHz with the SD821.

No telling when this updated SoC will find its way into consumer devices, with the Snapdragon 820 currently available in the Samsung Galaxy S7/S7 Edge, LG G5, OnePlus 3, and a few others.

Phononic's New Hex 2.0 TEC Is CPU Cooling Alternative For SFF Systems

Subject: Cases and Cooling | July 9, 2016 - 05:57 PM |
Tagged: thermoelectric, SFF, air cooling, TEC, mini ITX, phononic

An interesting cooling option for small form factor systems popped up in my email recently that is a new twist on an old technology. A company called Phononic has developed the Hex 2.0 which is a compact heatsink that pairs a tower air cooler with a TEC baseplate. At 810 grams and measuring 125 mm tall, the Hex 2.0 is Mini ITX friendly and is claimed to be competitive with closed loop water coolers with up to 240mm radiators (more on that below).

Phononic Hex 2 TEC Cooler.jpg

Hex 2.0 uses many of the same high quality components and design choices of traditional tower air coolers. A shrouded 92mm fan is sandwiched between two aluminum heatsinks with 40 fins each. There are eight 6mm heatpipes  that pull heat from the hot side of the thermoelectric (TEC) cooler and dissipate the heat. The TEC (which has a copper baseplate) uses an electric current and two dissimilar conductors and the principle of electron transport to pull heat from the “cold side” of the cooler to the “hot side” of the cooler. That hot side then needs to be cooled, and Phononic has chosen to use a tower air cooler for the job (people in the past have also paired TECs with water loops). The TEC is the notable bit about the Hex 2.0, and is what allows the small heatsink to offer as much cooling performance as it does in such a small package.

Hex 2.0 has connections for a 4-pin CPU_Fan connector, Mini USB for software monitoring and control, and a 6-pin PCI-E power connector. The four pin controls the 92mm fan which typically idles at 1000 RPM but can max out at 2,650 RPM, 33 dBA, and 44 CFM. The Mini USB connects to the motherboard and users can use a dashboard application to monitor the cooler, choose a cooling mode (to balance noise and performance), and control the LEDs on the cooler. The 6-pin connector powers the TEC cooler which appears to be capable of drawing up to 35W of power. The fan is able to spin down to zero RPM when the processor is not under load as the TEC and heatsink is able to pull and dissipate enough heat without the fan though the exact point where it would need to turn on will depend on your case and its own airflow.

Interestingly, this product is already available and reviews have already been posted around the net. According to TweakTown, the Hex 2.0 does indeed compete with 120mm liquid coolers such as the Silverstone Tundra TD03 (which is a decent cooler that I’ve used before) and Antec Kuhler H20 1250 (I’ve not tested that one but Morry did a full review of it). When placed in “insane mode” and the fan is allowed to spin up to maximum RPMs, the Hex 2.0 thermoelectric cooler actually beats the 240mm Corsair H100i GTX in quiet mode. While it will be louder, that is pretty impressive to see a 92mm fan HSF up there in cooling performance with a much larger water cooler!

This cooler is nicely packaged in a silver aluminum and black nickel plated aesthetic. Cooling performance seems to make it a possible alternative cooling option for SFF builds that can give you similar cooling performance in a case where a pump and radiator would be difficult or impossible for fit. That’s the upside. The downside to this cooler is the price. At $149.99, this is going to be a tough sell though it is not entirely unexpected considering the niche nature of it. The 1 year warranty leaves a lot be desired as well, I would have liked to see something a bit longer especially at that premium price.

What are your thoughts on this pint sized TEC(h)?

Silverstone's TD03-SLIM, small and quiet AIO watercooling for your SFF systems

Silverstone's TD03-SLIM AIO cooler is designed to fit in anyone's case, and their budget as well.  The radiator is a mere 153x120x22mm, a measurement which includes the fan and the tube is 310mm in length to allow you flexibility when placing it in your system.  The size does mean that it cannot cool as effectively as larger AIO watercoolers and should not be used in overclocked systems, however it does operate more quietly than other coolers of similar size.  Drop by Modders-Inc for a closer look.

"One of the good things about AIO CPU coolers is that you do not have to worry about component clearance for the most part on your motherboard. Since memory manufacturers have all but given up making sensibly sized RAM heatspreaders the standard, AIO's have become the cooler of choice for many."
