Tagged: meetup, london, giveaway, contest, Chromebook, arm

For a short romantic summer trip, Josh Walrath and I (Ryan Shrout) will be heading across the pond to London, England! With the primary goals of technology education and beer consumption, we thought it would be prudent to invite any and all PC Perspective fans in the area to join us for a night of talking tech, comparing beer preferences and just saying hello!

On Thursday April 27th starting 7:30pm, you will find Josh and me sitting in a dimly-lit booth at the Momentus Bar inside The Cumberland Hotel located at Great Cumberland Place London W1H 7DL. We have no specific agenda but will probably be there until at least midnight, hamming it up with anyone that walks over.

G.Skill Releasing DDR4 4333 MHz Memory Kit, Working on DDR4 4500 MHz

Subject: Memory | April 22, 2017 - 04:40 PM |
Tagged: z270, G.Skill Trident Z, G.Skill, dual channel, ddr4

For enthusiasts with a need for speed, G.Skill unleashed a new DDR4 memory kit recently that ratchets up two 8GB modules to 4333 MHz out of the box. The new 16GB kit will soon take the top spot in the company’s Trident Z series and will come with the traditional brushed metal heat spreader with red accent.

00_tridentz_x2.png

The new 16 GB (2 x 8GB sticks) Trident Z memory kit was validated on Intel’s Z270 platform using an Asus ROG Maximus IX Apex motherboard and an overclocked Intel Core i5-7600K. (The processor was clocked at 4200.20 MHz on a x40.0 multiplier and 104.98 MHz bus speed.) The DDR4 kit is running with CAS latencies of 19-19-19-39 and is needs 1.40 volts.

Not content to sit on its laurels, G.Skill is reportedly also working on cranking speeds up even further with a prototype DDR4 kit running at 4400 MHz and a “proof of concept” test of a 16 GB kit running at 4500 MHz. The DDR4-4500 kit is being stress tested while specifications are still under development and it will be “some time” before it is ready for market. G.Skill did manage to at least run Windows and some benchmarks at those RAM clock speeds though using the same Z270 platform listed above (with the Core i5 7600K clocked at 4360.36 MHz on a 108.98 MHz bus and x40.0 multiplier). The benchmark runs reported up to 65 GB/s write speeds, 55 GB/s read speeds, and 52 GB/s copy speeds specifically. DDR4 has come a long way in the speed department to where it is today and apparently still has room to grow.

01_ddr4_4500mhz_bandwidth.png

Unfortunately, as is the case with most announcements of this nature, no official pricing and availability was mentioned. Looking around online, I would expect the 16GB DDR4-4333 kit to come in somewhere around $280 and be available within the next month or so.

I would love to see what a kit this fast would do for Ryzen as far as alleviating the CCX-to-CCX bottleneck over the Infinity Fabric assuming the Ryzen memory controller can handle those speeds! Also, faster memory has helped AMD’s APUs in the past, so these extremely fast kits that are coming out should pair well with AMD's upcoming Raven Ridge though they will need to come down in price a lot to actually meet the budget of a good budget gaming build (right now with the kits in the $250+ range it would be better to just put the premium into a graphics card – though that kind of defeats the purpose of using the APU heh).

Windows 10 Cloud ("S"?) Performance Targets Leaked

Subject: General Tech | April 22, 2017 - 12:49 PM |
Tagged: windows 10 cloud, windows 10, uwp, microsoft

The upcoming version of Windows that can only install applications from the Windows Store, Windows 10 Cloud, will be Microsoft’s latest attempt at locked-down devices, like Windows RT was back in the Windows 8.x days. The goal is to take on the Chromebook market, which is similarly locked down to Google Chrome and Google Play Store apps (although Google allows developer sideloading). To be fair to Windows 10 Cloud, it can be upgraded to Home or Pro to run Win32 applications for a fee, although that somewhat flies in the face of “streamlined, simpler experience” if you acknowledge a monetary value in unlocking the features you claim those users theoretically don’t want.

Preamble and opinion aside, it would seem that Microsoft is hoping to push OEMs into making decent devices. They are recommending a minimum specification of quad-core Celeron, 4GB of RAM, >40 Wh battery, and “fast eMMC or SSD” storage. This last note about “fast” eMMC amuses me, because it not-so-subtly telegraphs that cheap laptops, despite having technically solid state memory, don’t have a noticeably better experience than typical hard drives.

Microsoft is expected to discuss the initiative on May 2nd at their #MicrosoftEDU event.

Oculus App Version 1.14 Released

Subject: General Tech | April 22, 2017 - 02:37 AM |
Tagged: Oculus, oculus rift

Oculus has updated their Oculus App to version 1.14. This release has two noteworthy features: full support for 360-degree tracking with three sensors, and the Touch controller can now be used with some, but not all, games that were previously gamepad-exclusive. For the latter, you will need to check with each specific game in the Oculus store, where it will be listed with a “Touch (as gamepad)” tag.

oculus-2017-touch360114.png

As for the former, Oculus has been allowing 2- (like the Vive) and 3-sensor setups for 360-degree tracking for a while, but experimentally. They have apparently settled on the three-sensor setup for final support, though. According to their documentation, they recommend that two of the sensors are plugged into USB 3.0 or higher, while leaving the third on USB 2. Specifically, the USB 2-connected sensor will be the one behind the user, with the two USB 3.0 sensors sitting out in front; to visualize this, imagine stereo speakers sitting on either side of your TV, with only one surround sound speaker behind the user. It will be interesting to see how Oculus two-sensor, Oculus three-sensor, and Vive two-sensor compares, especially since the last two are (in the case of Oculus, now) officially supported, but the first one isn’t.

While I don’t currently have a Rift, Oculus apparently delivers updates on a staggered schedule. Don’t be surprised if your system isn’t pushed to the new version immediately.

Rumor: GeForce GT 1030 Planned, Potentially with GP108

Subject: Graphics Cards | April 22, 2017 - 12:53 AM |
Tagged: pascal, nvidia, gt 1030, gp108

Expreview.com (machine-translated from Chinese) believes that NVIDIA will launch the GeForce GT 1030 to compete in the low-end. It’s difficult to tell how confident they are about this next part, due to the translation, but they believe that it will be based on a new Pascal design, GP108, rather than a further-disabled GP107 (as seen in the GTX 1050 and GTX 1050 Ti). Those parts have 640 and 768 CUDA cores, respectively, which might be where their estimate of 512 CUDA cores for GP108 comes from.

nvidia-geforce.png

As for the merits as a product, it seems a little odd to me. There is some room for it in terms of performance, sliding between the GTX 1050 and integrated graphics with a GTX 750-class part, just with higher clocks and/or lower power due to the Pascal architecture. It does seem risky, though, considering the GTX 1050 already occupies the $110 USD price point.

The post also suggests that the cards will have 1 GB and 2 GB variants.

Twitch Announces New Affiliate Program

Subject: General Tech | April 21, 2017 - 07:49 PM |
Tagged: twitch, pc gaming, amazon

While Twitch had quite a large lead as a streaming service, it had a fairly large gap between its regular creators and their “Twitch Partners”. If you weren’t a Twitch partner, you couldn’t directly monetize your stream, guarantee that your stream would be transcoded, and so forth.

twitch-2017-checklogo.png

That isn’t changing, but they are introducing an easier to obtain, middle tier that will have some, but not all, of the Partner perks. “Twitch Affiliate” is this middle-ground, and, while it is invite-only, it is open to pretty much anyone who intends to stream on a regular basis. Specifically, the threshold is about 500 online minutes in a month, spread out over at least seven days, and an average of at least three viewers at the same time; you will also need at least 50 followers. If you stream a few times per week, this is not a very high bar, but it’s still not automatic.

I should note that Twitch will only consider the previous 30 days, rolling.

The goal of this new tier is to provide some support for streamers, as they try to find their on-ramp to being a Twitch partner. At first, only the (relatively controversial) “Bits” system will be available for monetization, but other revenue streams, like video ads, should follow. Also, while you’re not guaranteed to receive video transcodes, Affiliates get priority access to whatever is left over from the Partners.

Personally, I’d like a guarantee that transcodes would be available, because I don’t want to occasionally alienate some viewers by sending Twitch too high of a bitrate for the, let’s say even just 10% of the time, that lower-quality versions would be unavailable. It still puts pressure on me to lower the quality that I send Twitch, which will often result in worse VOD quality. (I realize that you can use multiple encodes… and I currently do… but certain things, like frame rate, need to be consistent – at least with the current version of OBS Studio.)

Twitch should begin to contact eligible streamers soon, and will continue rolling in new users as they become eligible. Even then. it's not an immediate, automatic thing, though.

Move over modular PSUs and mice, the Epicgear Defiant is a modular keyboard.  What that actually means is that you can swap the actual switches on the keyboard, as long as they are Modular Matrix Structure switches.  The MMS switches as described as analogous to Cherry MX switches, though the colours do not translate directly and The Tech Report found them to be of equivalent quality.  In their testing they found that gaming with mismatched switches was somewhat unpleasant, so make sure to get a full set of the ones you plan to use.  The full review can be found here.

"Some gaming keyboards offer customizable backlighting and key caps to change up the feel of the keys underneath one's fingers. EpicGear's Defiant keyboard goes one better and lets gamers change out its key switches themselves for a different tactile experience. We switched around the Defiant's clickers to see if the feature upped our game."

Cooler, Quieter, Faster - CORSAIR Launches the Hydro GFX GTX 1080 Ti

Subject: Graphics Cards | April 21, 2017 - 02:59 PM |
Tagged: corsair, msi, gtx 1080 ti, nvidia, factory overclocked

Corsair partnered with MSI to produce the Hydro GFX GTX 1080 Ti, which has integrated watercooling based around the Corsiar H55 AiO cooler.  That cooler is used to support a factory overclock of 1,506 MHz Core, 1,620 MHz Boost and a memory frequency of 11,124MHz, though with the watercooling many will seek to find exactly how much more they can squeeze out of the silicon.

unnamed.jpg

According to their own testing, the GPU barely breaches 40C under load which translates into a higher sustained boost clock.  The ML120 LED PWM fan attached to the radiator can be manually set to run between 400-2,400 RPM to allow users to better control how the card operates.  This release adds to Corsair's previous offering, a GTX 1080 cooled with the same H55.

Hydro-GFX-1080Ti-Core-Clock-Over-Time.jpg

FREMONT, CA – April 20th, 2017 - CORSAIR®, a world leader in enthusiast memory, PC components and high-performance gaming hardware today announced the release of the new CORSAIR Hydro GFX GTX 1080 Ti all-in-one liquid cooled graphics card. Combining the extreme gaming horsepower of the NVIDIA® GeForce® GTX 1080 Ti GPU with world-renowned CORSAIR Hydro Series liquid cooling and magnetic levitation airflow, the Hydro GFX GTX 1080 Ti delivers the phenomenal performance of an overclocked GTX 1080 Ti with all the benefits of liquid cooling. Cooler temperatures, lower noise, higher clock speeds, and easy installation combine to allow the Hydro GFX GTX 1080 Ti to offer all the performance, with none of the compromises. Developed in partnership with the expert graphics team at MSI®, the Hydro GFX GTX 1080 Ti is powered by the NVIDIA GeForce GTX 1080 Ti, the most advanced NVIDIA GeForce GPU ever made. Boasting an irresponsible level of graphics processing performance, the GTX 1080 Ti features 11GB of GDDR5X memory, 3,584 CUDA Cores and a massive 352-bit memory bus, allowing it to drive today’s most demanding games and graphics applications at not just ultra-detail settings and high frame-rates, but stunning 4K resolution; it’s the ultimate GeForce GPU for PC enthusiasts who demand nothing but the best. The Hydro GFX GTX 1080 Ti pushes that performance even further, with a factory overclocked GPU core frequency of 1,506 MHz, boost frequency of 1,620 MHz and a memory frequency of 11,124 MHz, squeezing every frame per second, polygon and pixel out of the GTX 1080 Ti GPU.

The improvements aren’t just in MHz; with the Hydro GFX GTX 1080 Ti, CORSAIR takes NVIDIA’s best and makes it better. By equipping the GPU with a CORSAIR Hydro Series H55 liquid cooler, the heat produced by the GTX 1080 Ti GPU is efficiently channelled away by a micro-fin copper base to a 120mm radiator, allowing heat to be rapidly dissipated and exhausted out of your PC rather than build up inside. The result is up to 50 percent lower GPU temperatures, which in turn allows the Hydro GFX GTX 1080 Ti to boost its GPU clock speeds higher for longer, producing up to ten percent faster performance versus a stock GTX 1080 Ti. What’s more, with quick and easy installation into most 120mm case fan mounts, the Hydro GFX GTX 1080 Ti and its radiator are easy to fit into almost any PC case.

To cool the fastest GeForce GPU ever, CORSAIR selected its most advanced 120mm cooling fan, the ML120 LED. CORSAIR ML Series fans harness magnetic levitation technology to physically suspend the fan rotor away from the fan motor when in operation. This greatly reduces friction and fan noise, allowing the Hydro GFX GTX 1080 Ti to run cool while the ML120 spins at incredibly low noise levels, even with the GPU at full load. What’s more, with 4-pin PWM fan control and a 400-2,400 RPM range, you can tweak and tune the Hydro GFX GTX 1080 Ti’s cooling to suit your system – cool and quiet, or maximum airflow for the lowest temperatures and highest overclocks.

Combining the very best of NVIDIA Pascal GPU architecture, MSI graphics card design and both CORSAIR Hydro Series liquid cooling and magnetic levitation airflow, the CORSAIR Hydro GFX GTX 1080 Ti is the GTX 1080 Ti, but cooler.

Specifications:

  • GPU: NVIDIA GeForce GTX 1080 Ti
  • CUDA Cores: 3,584
  • Interface: PCI Express 3.0 x16

Windows 10 Releases Target ~September and ~March

Tagged: windows 10, microsoft

Now that Microsoft has pushed their third major version of Windows 10, the Creators Update, the company has decided to settle on a six-month rotation. This is similar to how the Ubuntu distribution of Linux pushes updates, although Windows 10 will be targeting September and March rather than Ubuntu’s October and April (and Ubuntu has a different long-term support model, as we’ll discuss below). More importantly, it’s designed to occur at the same time as Office 365 ProPlus updates, so IT departments can certify and roll out both at the same time.

windows-10.png

The previous release cycle was a little… chaotic. The November Update occurred about three and a half months after the initial release, followed almost nine months later by the Anniversary Update. Seven months after that, the Creators Update landed, which brings us to today.

Each version will be supported for eighteen months.

One of the latest WebVR experiments puts an emulated Windows 3.11 terminal in a virtual space. In it, you can play Minesweeper, Solitaire, and generally mess around. Because it’s a WebVR demo, certain browser, OS, and VR headset combinations will also work, in case you wanted to feel like you were actually in front of a beige box.

If you’re using it without WebVR, then it will appear as a static 3D scene. Make sure you enable mouse pointer lock, because you will need to use the virtual mouse pointer, not your actual mouse pointer. It will ask you when it’s loaded and focused, but your browser will probably require you to click allow or something.

Interesting Blender Updates for Upcoming Versions

Subject: General Tech | April 21, 2017 - 02:49 AM |
Tagged: Blender

The Blender Foundation and volunteers have been quite busy, especially over the last few weeks. Two major changes that are prepared for Blender 2.79: near-parity between CUDA and OpenCL, and an implementation of the Disney PBR shader.

Aside: A physically-based (“PBR”) shader allows modeling a bunch of common materials, such as plastics, ceramics, metals, and so forth, using parameters that are independent of lighting. This means that you can reuse the same object and material in all of your scenes, and it will behave like we expect it would given the environment. For instance, PBR materials account for conservation of energy, so objects get shinier as they get smoother, but they also look darker off-axis because less light is being diffusely scattered.

blender-2016-caminandes3-llama.jpg

While it was always possible to render in Cycles with a PBR workflow, you needed to create your own node setup, which typically consisted of about seven or eight elements connected in a specific way. When this new version lands, you will just need to connect the appropriate textures and colors to their corresponding pins in this node. The Disney-based Principled BSDF accounts for albedo (base color), subsurface scattering, metallic, specular, roughness, anisotropic reflections, sheen, clearcoat, index of refraction, and transparency.

blender-2017-openclperf.png

Update (April 21st @ 5:35pm): Blah! I forgot to embed the chart. Here it is.

Now we get to “near-parity between CUDA and OpenCL”. According the Blender Foundation, OpenCL can support all features found on CUDA with the exception of correlated multi jitter. This is accompanied by a graph, embed above, showing the RX 480 beat the GTX 1060 in a variety of benchmark scenes. Unfortunately, at the same time, GPU-accelerated rendering in Cycles now requires GCN 2.0 and up, which is the AMD R9 290 and later. Blender will still work on older cards, like the R9 280 or, heck, probably even the Radeon HD 4890, but the final render will need to be done on the CPU.

Blender 2.79 doesn’t have a firm release date, but the code freeze schedule has it expected for some time in either May or June.

AMD Releases Radeon Software Crimson ReLive 17.4.3

Subject: Graphics Cards | April 21, 2017 - 02:12 AM |
Tagged: amd, graphics drivers

During the lull in game releases, AMD has released a new graphics driver with official, WHQL-certified support for Windows 10 Creators Update. As we’ve discussed in the past, I tend to err on the side of, “If you do a decent job at internal QA and the user can choose to skip a version or three, then rapid release is probably better than sitting around for a Microsoft certificate”. I mean, why not push out fixes as they are available if there’s no obvious downsides?

amd-2016-crimson-relive-logo.png

Every so often, a WHQL version needs to be certified, though, if only to be accepted into Windows Update. Note that I don’t actually know whether this specific driver will be pushed by Microsoft after an update to the Creators Update – it’s just an example of a situation where WHQL matters.

That aside, the release notes for Radeon Software Crimson ReLive 17.4.3 do not state any specific fixes or changes. The main reason for this driver is to support the Creators Update for Windows 10, as well as add support for the new Radeon RX 570 and Radeon RX 580 graphics cards.

A form of 3D stackable non-volatile memory that promised 10x the density of DRAM and 1000x the speed and endurance of NAND. These were bold statements, and over the following months, we would see them misunderstood and misconstrued by many in the industry. These misconceptions were further amplified by some poor demo choices on the part of Intel (fortunately countered by some better choices made by Micron). Fortunately cooler heads prevailed as Jim Handy and other industry analysts helped explain that a 1000x improvement at the die level does not translate to the same improvement at the device level, especially when the first round of devices must comply with what will soon become a legacy method of connecting a persistent storage device to a PC.

Did I just suggest that PCIe 3.0 and the NVMe protocol - developed just for high-speed storage, is already legacy tech? Well, sorta.

That 'Future NVM' bar at the bottom of that chart there was a 2-year old prototype iteration of what is now Optane. Note that while NVMe was able to shrink down the yellow bar a bit, as you introduce faster and faster storage, the rest of the equation (meaning software, including the OS kernel) starts to have a larger and larger impact on limiting the ultimate speed of the device.

Before getting into the first retail product to push all of these links in the storage chain to the limit, let's explain how XPoint works and what makes it faster. Taking random writes as an example, NAND Flash (above) must program cells in pages and erase cells in blocks. As modern flash has increased in capacity, the sizes of those pages and blocks have scaled up roughly proportionally. At present day we are at pages >4KB and block sizes in the megabytes. When it comes to randomly writing to an already full section of flash, simply changing the contents of one byte on one page requires the clearing and rewriting of the entire block. The difference between what you wanted to write and what the flash had to rewrite to accomplish that operation is called the write amplification factor. It's something that must be dealt with when it comes to flash memory management, but for XPoint it is a completely different story:

XPoint is bit addressible. The 'cross' structure means you can select very small groups of data via Wordlines, with the ultimate selection resolving down to a single bit.

Since the programmed element effectively acts as a resistor, its output is read directly and quickly. Even better - none of that write amplification nonsense mentioned above applies here at all. There are no pages or blocks. If you want to write a byte, go ahead. Even better is that the bits can be changed regardless of their former state, meaning no erase or clear cycle must take place before writing - you just overwrite directly over what was previously stored. Is that 1000x faster / 1000x more write endurance than NAND thing starting to make more sense now?

Ok, with all of the background out of the way, let's get into the meat of the story. I present the P4800X:

TechARP just posted a video of AMD's Joe Macri discussing the new Ryzen processors from AMD.  It is not quite 20 minutes long which gives you a chance to quickly hear from AMD about what they feel the new architecture means for the company, as well as the impact it will have on gamers and enthusiasts.  He does mention the HSA Foundation and how AMD is working towards a basic change in how PCs utilize resources. They also embedded a link to a video featuring AMD's Radeon Product Marketing Manager, Adam Kozak, on the new 500 series if you have time.

Rumor: Intel Expects Coffee Lake and Basin Falls Early

Subject: Processors | April 19, 2017 - 08:00 PM |
Tagged: skylake-x, ryzen, kaby lake x, Intel, Core, coffee lake, amd

According to DigiTimes, Intel is expecting to release several new processors earlier than they had originally planned. That said, there are two issues with this report. The first point, which should be expected, is that it compares internal dates that were never meant to be public. It is not like Intel has changed their advertised roadmap.

The second problem is that it’s somewhat contradicted by Intel’s earlier, public statements.

Their rumor claims that Intel will push up the launch of Basin Falls, which is Skylake-X, Kaby Lake-X, and X299, by about two months (around June). It also claims that Coffee Lake, which was originally scheduled for January 2018, will be released in August 2017. Both of these moves are being attributed to AMD’s new products.

The potential, somewhat, sort-of contradiction comes from a tweet that Intel made back in February. In it, they said that the 8th generation of Core processors are expected for 2H’17. This time frame doesn’t include January, although it only barely includes August, too. If Intel was always planning on launching Coffee Lake for the “back to school” season, then at least that half of DigiTimes’ story would be completely incorrect. On the other hand, if Intel’s tweet was talking about a sampling / paper launch in December, with volume shipment soon to follow, then DigiTimes would be fairly accurate.

We don’t know unless someone at Intel confirms either-or.

As for Skylake-X and Kaby Lake-X, it would be interesting to see them launch at Computex / E3. Previous rumors (also from DigiTimes) that place it in the Gamescom, which is a huge gaming conference in Cologne. Interestingly, this rumor claims that only the four-, six-, eight-, and ten-core models will arrive at the time, with a twelve-core model waiting until the whole line was supposed to launch.

This omission makes me wonder if, in fact, Intel are rushing the launch, but they realize that they cannot get enough good chips to fill out the top-end SKU. In that case, it would make sense to push the smaller and partially-disabled chips out the door, while banking the big chips that can run all twelve cores at a reasonable voltage for some clock rate.

If so, that would, in fact, speak volumes about AMD’s roadmap (and Intel’s opinion of it).
