Tagged: steam sale, gaming
Is that list of Steam games you own but haven't played getting a little shorter? Well, there is a solution to that as the on of the most dangerous causes of impulse buying starts tomorrow. Paypal let the cat out of the bag and Rock, Paper, SHOTGUN spotted it, along with the launch time for the UK, 6pm BST on 22 June. The reason PayPal revealed the start of the sale is because they are offering a bit of a deal in the UK and possibly the rest of the world, if you buy more than £20 of games and pay for it with PayPal you get an extra £5 off.
Perhaps this is a good time to head out of town and spend the weekend somewhere without internet connectivity?
"I assume you young people will be dragging your camping stools to the Steam storefront from 21 June, nursing a thermos of something nutritious and exchanging stories about the time you queued for something else with your fellow queuers."

[H]ard|OCP were at AMD's launch of the new EPYC family of server CPUs and captured the presentation and slide deck in a series of photos you can take a look at right here. They cover the work being done with HP and Dell, as well as with internet service providers such as Microsoft's Azure platform and China's Baidu. They even give you a look at some of the products which will be launched running on Supermicro platforms. AMD is looking very attractive to server builders at the moment, a feeling you may already have garnered from reading Ryan's take on EPYC.
"AMD held it official EPYC enterprise CPU launch today in Austin, TX. If you are not aware of EPYC, it is quite simply AMD's effort to get back into the datacenters that are now firmly held by Intel Xeon processors. What do you get when you take 4 Ryzen 7 CPUs and put those down on a single package with Infinity Fabric? You would be correct, its EPYC."

Tagged: input, Palette, blame canada, MIDI
As you can see, the Palette is not your normal keyboard nor mouse. Instead is is a collection of buttons, dials and sliders which communicate via the MIDI standard and is intended to help you with programs like Adobe Premier Pro, Photoshop, or Capture One. The Palette can be rearranged however you like, magnets hold it together to ensure that signal can travel between the blocks in whatever arrangement you prefer. The core module, with the LCD screen, houses the USB connector to plug it into your system as well as the Atmel AT90USB1286 8-bit brains of the device. You can connect up to 18 modules due to the power delivery limitations of USB, or 32 if you can provide additional power. TechPowerUp found numerous uses for the device, drop to check it our and perhaps to be inspired.
"Palette is a startup that aims to elevate the current standard of human-computer interaction. Their modular controllers based off the MIDI standard use a combination of buttons, dials, and sliders to lower workflow time for content creators. The PaletteApp driver helps with built-in support for over 15 popular programs from Adobe and others, and profile support enables quick changes in functionality for individual modules."

Researchers from the University of Maryland have come up with an interesting new use for the tobacco mosaic virus; significantly increasing the surface area of electrodes. The increase is quite impressive, a 3.6-fold improvement in areal capacitance over a planar equivalent due to the increased surface area created by the nickel oxide coated TMV. Not only does this research offer improvements in supercapacitors it opens up a new area of research which could enhance a wide variety of electrically charged devices. Drop by Nanotechweb for a look at the science behind this.
"Scientists in the US have devised a microfabrication method that uses capillary channels in a photoresist to position nanorods of the tobacco mosaic virus (TMV). The team used the quick and simple new approach to create a supercapacitor with nanostructured electrodes, and the method can be applied to construct many other microdevices requiring high surface areas."

Tagged: microsoft, windows, windows server
Microsoft seems to want to release feature updates for their software twice per year, once in the fall, and once in the spring. First, Office 365 announced that it would adopt a semi-annual schedule, targeting September and March, give or take a bit. The Windows team then announced that they would follow in Office’s footsteps.
It’s interesting, because Windows Server typically pushes out two major versions every four or five years: one with a number, and another with that same number alongside an R2 suffix. Each of these lines up with a consumer refresh of the NT kernel, although both Windows Server 2003 and Windows Server 2003 R2 used the same kernel... because Windows XP lasted a while.
Sure, a lot of a name would normally be marketing, but it also gated the major features that Microsoft was able to add (because they wanted a single Windows release to interact with software fairly uniformly across its lifecycle for enterprise reasons). Now, with the whole company pushing the “as a service” model, even Windows Server will be on the feature release treadmill.

Barely the size of a Threadripper CPU, the Racing X370GTN ITX motherboard is a decent platform to build a Ryzen powered SFF system on. Biostar kept the design fairly simple, to keep the costs down on this motherboard but don't worry, they did include RGB headers for 5050 RGB LED light strips and you can set up your personalized light show using the Racing GT utility. Even with the compact design, Hardware Canucks were able to fully populate the two DIMM slots even with a Prolimatech Mega Shadow cooler installed, they did discover that users of AiO watercoolers will have to ensure to rotate the cooler to ensure the tubing does not block the closer DIMM however. The M.2 slot has been relocated to the back of the motherboard due to the size constraints of the board which did not impact performance. Pop by to take a look at this ~$110 motherboard if you are in the market for an ITX Ryzen system.
"ITX motherboards have finally arrived for AMD's Ryzen and in this first review we look at Biostar's brand new Racing X370GTN. Can its diminutive size belie its true performance?"

It has been over 20 years since Atari launched their Jaguar system, the last piece of hardware that company would make; until now perhaps. There was a mysterious announcement and the launch of a website with little more information than a movie featuring rendered wood grain and plastic. You can sign up at ataribox.com to become the first to know, if Nintendo decides to share more information. It will be very interesting to see what components they have picked to run this new console, considering the high specifications of the new Xbawkx they will either need high end silicon or a much lower price to compete. The video is down below and you can pop over to The Inquirer for more speculation if you so desire.
"The iconic company, which has had more lives than Garfield in a blender, is to release the Ataribox, which so far is shrouded in mystery, aside from the classic wood panelling that lovers of the 2300 and 2600 will know only too well."

Tagged: ifixit, recycling, microsoft, surface laptop
It’s no surprise that many devices have been sacrificing user-serviceability in favor of small, light, and fast. In fact, it’s not uncommon to see device manufacturers forego even the ability to recycle them when they’re done, even if their components are theoretically made out of recyclable materials. (It doesn’t matter if it’s mostly metal and glass if they’re all glued together in a way that takes forever to separate.)
In this case, the new Microsoft Surface Laptop gets a big zero from iFixit. For context, the iPad 3, which stirred a bit of controversy a few years ago, scored a two out of ten. Two major points that they made against it are “You can’t get inside without inflicting a lot of damage” and “The battery is difficult and dangerous to replace”. Yikes.
To be clear, sacrificing user-serviceability isn’t necessarily a bad thing (although I’d argue that recyclable components should always be installed in a recyclable way). As long as the user is aware that they are trading-off the ability to fix or upgrade the thing they purchase, then they can make the value decision for themselves.
And now potential customers know.

During E3, AMD released a new graphics driver, 17.6.2. It doesn’t list any general improvements, and just a single fixed issue: improved performance on DiRT 4 with 8xMSAA with the most recent game build. If you play this game, then you should consider updating your graphics driver.
If you aren't intending to play DiRT 4, and you're already on 17.6.1, then you could probably skip it. That said, if you have an issue, and it’s not listed in the Known Issues section, because those definitely aren’t fixed yet, then you can give it a try.

Tagged: pc gaming, hitman
During the most recent SquareEnix financial earnings release (PDF) they announced that they would withdraw from IO Interactive, who makes the Hitman series of video games. Their most recent release, Hitman 2016, is one of our major benchmarks because it was one of the first titles to rework its engines for DirectX 12 (and it’s also a very pretty game). The previous game, Hitman: Absolution, was also featured on one of our live streams because it was an AMD Gaming Evolved / Never Settle title.
IO Interactive has followed-up with their own announcement. As of last Friday, they are now an independent studio, and they were able to negotiate both their management and the Hitman IP. “We are now open to opportunities with future collaborators and partners to help strengthen us as a studio and ensure that we can produce the best games possible for our community.” In other words, they don’t seem to have any publisher lined up, but the Hitman franchise should be enticing for many AAA-level companies.
Just a couple weeks earlier, IO Interactive also announced that new purchases of Hitman would automatically buy all episodes from the first season. Steam will, however, detect existing episodes and only bill you for the ones you’ve missed. They say that “these changes will help us lay the foundations for our future plans for HITMAN” but it’s unclear what they mean at this point.

Tagged: nicehash, mining, cryptocurrency
Over the last several weeks, we have been experimenting with the most recent GPU-shortage-inducing coin mining craze, with Ken's article as a jumping off point. On a recent podcast, I mentioned the idea of running a community coin mining group that would be used as a way for individuals to contribute to PC Perspective. I received several requests for the wallet and setup information to make this happen, so I thought it would be worth while to gather all the necessary links and info in a single location.
We have been running a Patreon campaign for a couple of years now on the site as a way to provide an avenue for those readers and viewers that find PC Perspective a useful resource to the community and directly contribute. It might be because you want to keep the PCPer staff stable, it could be because you use an ad blocker and are looking for a way to even things out, etc. But there are always some that don't have the ability or desire to sign up for a new service so contributing your empty GPU cycles is another option if you want to donate to the PCPer team.
How do you do it? Ken has created a step by step guide below - thanks for your support in this and all of our previous endeavors!
- Bitcoin: 1HHhVWPRpCUst9bDYtLstMdD7o5SzANk1W
- Ethereum: 0xa0294763261aa85eB5f1dA3Ca0f03E1B672EED87
For those of you who may be curious to try out this mining stuff on your personal computer, we would recommend looking into the NiceHash application.
For those of you who haven't read our previous article, NiceHash is a service that connects buyers of GPU mining power to sellers who have spare hardware that they are looking to put to use.
As a warning, if you are planning to mine please be aware of your power consumption. To get a good idea of this, you can look up the TDP of your given graphics card, multiply that wattage by the hours you plan to mine, divide by 1000 to translate from watts to kilowatts, and multiply that by the rate you pay for electricity (this can be found on your power bill in cents per Kilowatt/Hour in the US). (So it's watts*hours*days/1000*kw/hr rate - Thanks CracklingIce)
Given the current rates of value for these cryptocurrencies, power is a small portion of the gross profit made by mining, but it is important to be aware of this before you are presented with a huge power bill that you weren't expecting.
First, download the latest version of the NiceHash miner application from their website.
After your download has finished, extract the ZIP file and load the NiceHashMiner.exe program.
Once the application has been launched and you've accepted the terms of the EULA, the NiceHash Miner will start to download the appropriate mining applications for your given hardware.
Note: during this installation process, your antivirus program might detect malware. These miner executables that are being downloaded are safe, but many antivirius programs flag them as malware because if they are found on your PC without your permission they are a telltale sign of malicious software.
After the installation process is completed, you be brought to the main screen of the application.
From here, choose the server location closest to you, add the Bitcoin address (in this case: 1HHhVWPRpCUst9bDYtLstMdD7o5SzANk1W), and choose a unique worker name (up to 7 characters long).
From here, hit the benchmark button, select the devices you want to mine on (we would recommend GPUs only, CPUs don't earn very much), and hit the Start button.
Once the benchmarking is done, you'll be brought back to the main screen of the application where you can hit the Start button.
Once you hit the start button, a command prompt window will launch where you can see the miner at work (this can be hidden from the NiceHash setting pane), and you can view the stats of your computer in the original NiceHash application window.
And that's it, your computer will now be mining towards the PCPER community pool!

The ASUS Cerberus is a little different from other headsets, for instance it uses 53mm drivers and two microphones, a removable boom microphone and an in-line microphone pemanently attached. For audiophiles, the headset has a 32 Ω impedance and 20-20,000 Hz frequency response and a somewhat muddy sound; for gamers it has very heavy bass which can make explosions quiet startling. TechPowerUp were not in love with the audio performance but found the headset to be extremely comforatable so it can be perfect for those who prefer comfort over a beautiful audio space.
"Asus Cerberus V2 is the successor to the company's bestselling headset. Now equipped with a stainless steel headband and the new "Essence drivers", it's supposed to be sturdier and better sounding.

MSI states their VR One is the world’s lightest and thinnest backpack PC system with high performance, which makes sense considering the utter lack of competition in that area. It may also claim to be the most expensive, as the price ranges from $1700 to $2300 in cost; [H]ard|OCP tested out the high end model in their recent review. Inside is a Kaby Lake Core i7-7820HK, 16GB of 2166MHz DDR4, dual M.2 storage drives, and the mobile version of the GTX 1070; certainly enough to power a Rift or Vive. The battery life is more impressive than you might expect, starting from 92% it lasted 1 hour and 37 and from 96% 1 hour and 41 minutes, with 2 hours required to recharge the battery over 95%. It is an investment but being able to experience VR without tripping on cords is an attractive proposition.
"The MSI VR ONE is quite simply a full PC that comes in the form of a backpack that allows you to connect your HTC Vive or Oculus Rift for a "wireless" VR experience. This VR ONE unit packs a GTX 1070 laptop GPU to hopefully supply us with the needed 90 frames per second performance required for a perfect Virtual Reality experience."

Tagged: xeon scalable, xeon, skylake-x, skylake-sp, skylake-ep, ring, mesh, Intel
Though we are just days away from the release of Intel’s Core i9 family based on Skylake-X, and a bit further away from the Xeon Scalable Processor launch using the same fundamental architecture, Intel is sharing a bit of information on how the insides of this processor tick. Literally. One of the most significant changes to the new processor design comes in the form of a new mesh interconnect architecture that handles the communications between the on-chip logical areas.
Since the days of Nehalem-EX, Intel has utilized a ring-bus architecture for processor design. The ring bus operated in a bi-directional, sequential method that cycled through various stops. At each stop, the control logic would determine if data was to be the collected to deposited with that module. These ring bus stops are located at memory controllers, CPU cores / caches, the PCI Express interface, memory controllers, LLCs, etc. This ring bus was fairly simple and easily expandable by simply adding more stops on the ring bus itself.
However, over several generations, the ring bus has become quite large and unwieldly. Compare the ring bus from Nehalem above, to the one for last year’s Xeon E5 v5 platform.
The spike in core counts and other modules caused a ballooning of the ring that eventually turned into multiple rings, complicating the design. As you increase the stops on the ring bus you also increase the physical latency of the messaging and data transfer, for which Intel compensated by increasing bandwidth and clock speed of this interface. The expense of that is power and efficiency.
For an on-die interconnect to remain relevant, it needs to be flexible in bandwidth scaling, reduce latency, and remain energy efficient. With 28-core Xeon processors imminent, and new IO capabilities coming along with it, the time for the ring bus in this space is over.
Starting with the HEDT and Xeon products released this year, Intel will be using a new on-chip design called a mesh that Intel promises will offer higher bandwidth, lower latency, and improved power efficiency. As the name implies, the mesh architecture is one in which each node relays messages through the network between source and destination. Though I cannot share many of the details on performance characteristics just yet, Intel did share the following diagram.
As Intel indicates in its blog on the mesh announcements, this generic diagram “shows a representation of the mesh architecture where cores, on-chip cache banks, memory controllers, and I/O controllers are organized in rows and columns, with wires and switches connecting them at each intersection to allow for turns. By providing a more direct path than the prior ring architectures and many more pathways to eliminate bottlenecks, the mesh can operate at a lower frequency and voltage and can still deliver very high bandwidth and low latency. This results in improved performance and greater energy efficiency similar to a well-designed highway system that lets traffic flow at the optimal speed without congestion.”
The bi-directional mesh design allows a many-core design to offer lower node to node latency than the ring architecture could provide, and by adjusting the width of the interface, Intel can control bandwidth (and by relation frequency). Intel tells us that this can offer lower average latency without increasing power. Though it wasn’t specifically mentioned in this blog, the assumption is that because nothing is free, this has a slight die size cost to implement the more granular mesh network.
Using a mesh architecture offers a couple of capabilities and also requires a few changes to the cache design. By dividing up the IO interfaces (think multiple PCI Express banks, or memory channels), Intel can provide better average access times to each core by intelligently spacing the location of those modules. Intel will also be breaking up the LLC into different segments which will share a “stop” on the network with a processor core. Rather than the previous design of the ring bus where the entirety of the LLC was accessed through a single stop, the LLC will perform as a divided system. However, Intel assures us that performance variability is not a concern:
Negligible latency differences in accessing different cache banks allows software to treat the distributed cache banks as one large unified last level cache. As a result, application developers do not have to worry about variable latency in accessing different cache banks, nor do they need to optimize or recompile code to get a significant performance boosts out of their applications.
There is a lot to dissect when it comes to this new mesh architecture for Xeon Scalable and Core i9 processors, including its overall effect on the LLC cache performance and how it might affect system memory or PCI Express performance. In theory, the integration of a mesh network-style interface could drastically improve the average latency in all cases and increase maximum memory bandwidth by giving more cores access to the memory bus sooner. But, it is also possible this increases maximum latency in some fringe cases.
Further testing awaits for us to find out!

It has been quite a while since Sebastian reviewed Corsair's Crystal Series 570X tempered glass case; so why not take another look? Over at Techgage you can revist this case with a view. They were impressed by the cooling included, three fans and a pre-installed fan hub for three more RGB fans as well as the air filter placements which help keep dust out of the case. There is no equivalent feature to get fingerprints off of the glass front and sides so you will spend some time cleaning up your case. Then again, if you are choosing a transparent enclosure, you likely spend a lot of time ensuring all your components are looking their best.
"Corsair’s Crystal series is named as such because of its use of tempered glass, and as the top dog in the current lineup, the 570X sports that tempered glass on all four sides. Despite its delicate frame, the chassis proved great to build with, and as we found out, its beautiful aesthetics don’t hurt its cooling efficiency."

Canada's equivalent of the USA's FCC, managed to collect enough backbone to utter a statement about directing Canadian mobile carriers to unlock any of their phones without charging money for doing so. The current going rate is around $50, a bit less if you trust that shady character in the alley.
They also murmured something about how it was inappropriate to allow a child to simply reply yes back to a text from their provider to authorize international roaming charges over $100 a month or data overage fees at $50. They politely inquired if the phone companies might consider following the CRTC's new suggestion that only the authorized account holder have approval, even if the teenager swears their parental unit totally said it was OK.
As is their wont, no mention of penalties was made nor did they seem to have acquired any teeth since last they pulled their heads out into the light. You can read more at Slashdot or the CBC, depending on your preference of comments.
"Canada's telecom regulator has announced that as of December 1st, 2017, all individual and small business wireless consumers will have the right to have their mobile devices unlocked free of charge upon request, while all newly purchased devices must be provided unlocked from that day forward."

Zotac recently unveiled a slimmed down GTX 1080 Ti graphics card that uses a dual slot and dual fan cooler with a short PCB. The aptly named Zotac GTX 1080 Ti Mini measures 8.3” (211mm) long and will be the smallest GTX 1080 Ti on the market. Despite the miniaturization, Zotac is still offering a decent factory overclock on the Pascal GPU (but not the memory) with a boost clock of 1620 MHz versus the reference boost clock of 1582.
Zotac uses two 8-pin PCI-E power connectors to drive the card with its GTX 1080 Ti GPU (3584 CUDA cores) and 11GB of GDDR5X memory clocked at 11 GHz. The slimmed down graphics card features a metal backplate, dual shrouded fans, and a heatsink with aluminum fins and five 6mm heat pipes. The card has three DisplayPort 1.4 ports, one HDMI 2.0b port, and one DL-DVI output with the card supporting up to four simultaneous displays.
The Zotac GTX 1080 Ti Mini should enable quite a bit of horsepower in small form factor systems. The graphics card is model number ZT-P10810G-10P and Zotac has it listed on its website. Unfortunately, Zotac is not yet talking pricing or availability for the shortened card.
It appears that overclocking is not out of the question, but I am curious just how far it could be pushed especially in a small case with tight quarters and less airflow.
