Phoronix wanted to test out how the new GTX 1070 and the R9 Fury compare on Ubuntu with new drivers and patches, as well as contrasting how they perform on Windows 10. There are two separate articles as the focus is not old silicon versus new but the performance comparison between the two operating systems. AMD was tested with the Crimson Edition 16.6.1 driver, AMDGPU-PRO Beta 2 (16.20.3) driver as well as Mesa 12.1-dev. There were interesting differences between the tested games as some would only support one of the two Linux drivers. The performance also varies based on the game engine, with some coming out in ties, others seeing Windows 10 pull ahead and even some cases where your performance on Linux was significantly better.
NVIDIA's GTX 1080 and 1070 were tested using the 368.39 driver release for Windows and the 367.27 driver for Ubuntu. Again we see mixed results, depending on the game Linux performance might actually beat out Windows, especially if OpenGL is an option.
Check out both reviews to see what performance you can expect from your GPU when gaming under Linux.
"Yesterday I published some Windows 10 vs. Ubuntu 16.04 Linux gaming benchmarks using the GeForce GTX 1070 and GTX 1080 graphics cards. Those numbers were interesting with the NVIDIA proprietary driver but for benchmarking this weekend are Windows 10 results with Radeon Software compared to Ubuntu 16.04 running the new AMDGPU-PRO hybrid driver as well as the latest Git code for a pure open-source driver stack."

Tagged: tesla, pascal, nvidia, GP100
GP100, the “Big Pascal” chip that was announced at GTC, will be coming to PCIe for enterprise and supercomputer customers in Q4 2016. Previously, it was only announced using NVIDIA's proprietary connection. In fact, they also gave themselves some lead time with their first-party DGX-1 system, which retails for $129,000 USD, although we expect that was more for yield reasons. Josh calculated that each GPU in that system is worth more than the full wafer that its die was manufactured on.
This brings us to the PCIe versions. Interestingly, they have been down-binned from the NVLink version. The boost clock has been dropped to 1300 MHz, from 1480 MHz, although that is matched with a slightly lower TDP (250W versus the NVLink's 300W). This lowers the FP16 performance to 18.7 TFLOPs, down from 21.2, FP32 performance to 9.3 TFLOPs, down from 10.6, and FP64 performance to 4.7 TFLOPs, down from 5.3. This is where we get to the question: did NVIDIA reduce the clocks to hit a 250W TDP and be compatible with the passive cooling technology that previous Tesla cards utilize, or were the clocks dropped to increase yield?
They are also providing a 12GB version of the PCIe Tesla P100. I didn't realize that GPU vendors could selectively disable HBM2 stacks, but NVIDIA disabled 4GB of memory, which also dropped the bus width to 3072-bit. You would think that the simplicity of the circuit would want to divide work in a power-of-two fashion, but, knowing that they can, it makes me wonder why they did. Again, my first reaction is to question GP100 yield, but you wouldn't think that HBM, being such a small part of the die, is something that they can reclaim a lot of chips by disabling a chunk, right? That is, unless the HBM2 stacks themselves have yield issues -- which would be interesting.
There is also still no word on a 32GB version. Samsung claimed the memory technology, 8GB stacks of HBM2, would be ready for products in Q4 2016 or early 2017. We'll need to wait and see where, when, and why it will appear.

Tagged: acer, security
North American customers of Acer who bought directly from them between May 12, 2015 and April 28, 2016 may have had their credit card numbers compromised. Their less than secure customer database contained customer names, addresses, card numbers, and three-digit security verification codes all of which have been siphoned off at least once. If this breach effected your account Acer will be sending a notification to you, you can see an example at The Register if you want to be sure you are receiving a valid notification. For those who have seen fraudulent charges already this will be too late to mitigate their pain but anyone who used Acer's online shop during that time period would do well to get their cards changed.
"Acer's insecure customer database spilled people's personal information – including full payment card numbers – into hackers' hands for more than a year."

Tagged: nvidia, graphics drivers
GeForce Hotfix 368.51 drivers have been released by NVIDIA through their support website. This version only officially addresses flickering at high refresh rates, although its number has been incremented quite a bit since the last official release (368.39) so it's possible that it rolls in other changes, too. That said, I haven't heard too many specific issues with 368.39, so I'm not quite sure what that would be.
As always with a hotfix driver, NVIDIA pushed it out with minimal testing. It should pretty much only be installed if you have a specific issue (particularly the listed one(s)) and you don't want to wait until one is released that both NVIDIA and Microsoft looked over (although Microsoft's WHQL certification has been pretty lax since Windows 10).
Oddly enough, they only seem to list 64-bit links for Windows 8.1 and Windows 10. I'm not sure whether this issue doesn't affect Windows 7 and 32-bit versions of 8.1 and 10, or if they just didn't want to push the hotfix out to them for some reason.

Tagged: asus, GTX 1080, strix, vbios
Yesterday, there were several news stories posted on TechpowerUp and others claiming that ASUS and MSI were sending out review samples of GTX 1080 and GTX 1070 graphics cards with higher clock speeds than retail parts. The insinuation of course is that ASUS was cheating, overclocking the cards going to media for reviews in order to artificially represent performance.
Image source: Techpowerup
MSI and ASUS have been sending us review samples for their graphics cards with higher clock speeds out of the box, than what consumers get out of the box. The cards TechPowerUp has been receiving run at a higher software-defined clock speed profile than what consumers get out of the box. Consumers have access to the higher clock speed profile, too, but only if they install a custom app by the companies, and enable that profile. This, we feel, is not 100% representative of retail cards, and is questionable tactics by the two companies. This BIOS tweaking could also open the door to more elaborate changes like a quieter fan profile or different power management.
There was, and should be, a legitimate concern about these types of moves. Vendor one-up-manship could lead to an arms race of stupidity, similar to what we saw on motherboards and base frequencies years ago, where CPUs would run at 101.5 MHz base clock rather than 100 MHz (resulting in a 40-50 MHz total clock speed change) giving that board a slight performance advantage. However, the differences we are talking about with the GTX 1080 scandal are very small.
- Retail VBIOS base clock: 1683 MHz
- Media VBIOS base clock: 1709 MHz
- Delta: 1.5%
And in reality, that 1.5% clock speed difference (along with the 1% memory clock rate difference) MIGHT result in ~1% of real-world performance changes. Those higher clock speeds are easily accessible to consumers by enabling the "OC Mode" in the ASUS GPU Tweak II software shipped with the graphics card. And the review sample cards can also be adjusted down to the shipping clock speeds through the same channel.
ASUS sent along its official statement on the issue.
ASUS ROG Strix GeForce GTX 1080 and GTX 1070 graphics cards come with exclusive GPU Tweak II software, which provides silent, gaming, and OC modes allowing users to select a performance profile that suits their requirements. Users can apply these modes easily from within GPU Tweak II.The press samples for the ASUS ROG Strix GeForce GTX 1080 OC and ASUS ROG Strix GeForce GTX 1070 OC cards are set to “OC Mode” by default. To save media time and effort, OC mode is enabled by default as we are well aware our graphics cards will be reviewed primarily on maximum performance. And when in OC mode, we can showcase both the maximum performance and the effectiveness of our cooling solution.Retail products are in “Gaming Mode” by default, which allows gamers to experience the optimal balance between performance and silent operation. We encourage end-users to try GPU Tweak II and adjust between the available modes, to find the best mode according to personal needs or preferences.For both the press samples and retail cards, all these modes can be selected through the GPU Tweak II software. There are no differences between the samples we sent out to media and the retail channels in terms of hardware and performance.Sincerely,ASUSTeK COMPUTER INC.
While I don't believe that ASUS' intentions were entirely to save me time in my review, and I think that the majority of gamers paying $600+ for a graphics card would be willing to enable the OC mode through software, it's clearly a bad move on ASUS' part to have done this. Having a process in place at all to create a deviation from retail cards on press hardware is questionable, other than checking for functionality to avoid shipping DOA hardware to someone on a deadline.
As of today I have been sent updated VBIOS for the GTX 1080 and GTX 1070 that put them into exact same mode as the retail cards consumers can purchase.
We are still waiting for a direct response from MSI on the issue as well.
Hopefully this debacle will keep other vendors from attempting to do anything like this in the future. We don't need any kind of "quake/quack" in our lives today.

Tagged: Zen, opteron, amd
We're beginning to see how the Zen architecture will affect AMD's entire product stack. This news refers to their Opteron line of CPUs, which are intended for servers and certain workstations. They tend to allow lots of memory, have lots of cores, and connect to a lot of I/O options and add-in boards at the same time.
In this case, Zen-based Opterons will be available in two, four, sixteen, and thirty-two core options, with two threads per core (yielding four, eight, thirty-two, and sixty-four threads, respectively). TDPs will range between 35W and 180W. Intel's Xeon E7 v4 goes up to 165W got 24 cores (on Broadwell-EX) so AMD has a little more headroom to play with for those extra eight cores. That is obviously a lot, and it should be, again, good for cloud applications that can be parallelized.
As for the I/O side of things, the rumored chip will have 128 PCIe 3.0 lanes. It's unclear whether that is per socket, or total. Its wording sounds like it is per-CPU, although much earlier rumors have said that it has 64 PCIe lanes per socket with dual-socket boards available. It will also support sixteen 10-Gigabit Ethernet connections, which, again, is great for servers, especially with virtualization.
These are expected to launch in 2017. Fudzilla claims that “very late 2016” is possible, but also that it will launch after high-end desktop, which are expected to be delayed until 2017.

Tagged: skyrim, bethesda
On Sunday, Bethesda had their E3 2016 press conference, where they announced a bunch of content that are relevant to PC gamers. One of them was Skyrim: Special Edition. It hasn't been added to their website yet, but it updates The Elder Scrolls V with new assets, shaders, and effects. On the PC, it will be free to anyone who has purchased the base game and all of its expansions.
Even better: it is also compiled as a 64-bit application.
One of the original Skyrim's limits, specifically for modders, was that it could only address a little over 3GB of system memory before crashing. Worse: RAM usage was interconnected with GPU memory usage, which further limits the number of assets you can actually load. While there are probably still plenty of ways for Skyrim to crash, especially when third-party content is injected, Skyrim: Special Edition will move the solid, 3GB wall.
DigitalFoundry also claims that the engine itself is updated to a newer branch itself, like what was used for Fallout 4. This makes sense, because several effects would be difficult to do on DirectX 9 (like volumetric god rays). Despite the newer engine version, Pete Hines of Bethesda said “basically, yes” when asked whether existing Skyrim mods would be compatible. This suggests that the internal API would be the same for at least the majority of cases. Interesting!
Skyrim: Special Edition will be available on October 28th.
ARM Releases Egil Specs
The final product that ARM showed us at that Austin event is the latest video processing unit that will be integrated into their Mali GPUs. The Egil video processor is a next generation unit that will be appearing later this year with the latest products that utilize Mali GPUs up and down the spectrum. It is not tied to the latest G71 GPU, but rather can be used with a multitude of current Mali products.
Video is one of the biggest usage cases for modern SOCs in mobile devices. People constantly stream and record video from their handhelds and tablets, and there are some real drawbacks in current video processor products from a variety of sources. We have seen the amazing increase in pixel density on phones and tablets and the power draw to render video effectively on these products has gone up. We have also seen the introduction of new codecs that require a serious amount of processing capabilities to decode.
Egil is a scalable product that can go from one core to six. A single core can display video from a variety of codecs at 1080P and up to 80 fps. The six core solution can play back 4K video at 120 Hz. This is assuming that the Egil processor is produced on a 16nm FF process or smaller and running at 800 MHz. This provides a lot of flexibility with SOC manufacturers that allows them to adequately tailor their products for specific targets and markets.
The cores themselves are fixed function blocks with dedicated controllers and control logic. Previous video processors were more heavy on the decode aspects rather than encode. Now that we have more pervasive streaming from mobile devices and cameras/optics that can support higher resolutions and bitrates, ARM has redesigned Egil to offer extensive encoding capabilities. Not only does it add this capability, but it enhances it by not only decoding at 4K but being able to encode four 1080p30 streams at the same time.
Egil will eventually find its way into other products such as TVs. These custom SOCs will be even more important as 4K playback and media become more common plus potential new functionality that has yet to be implemented effectively on TVs. For the time being we will likely see this in mobile first, with the initial products hitting the market in the second half of 2016.
ARM is certainly on a roll this year with introducing new CPU, GPU, and now video processors. We will start to see these products being introduced throughout the end of this year and into the next. The company certainly has not been resting or letting potential competitors get the edge on them. Their products are always focused on consuming low amounts of power, but the potential performance looks to satisfy even power hungry users in the mobile and appliance markets. Egil is another solid looking member to the lineup that brings some impressive performance and codec support for both decoding and encoding.

We have seen numerous examples of SilverStone's Argon series of heatsinks, dating back to the AR01 which Morry reviewed in 2014. The AR08 is a new member of the series, 285g and 92x50x134mm with a 92mm fan and a $35 price tag. The small size and price make a good choice for those on a budget and who chose a smaller case which precludes the use of a Morry special cooler. As you might expect, the competition for this cooler is the stock cooler which came with your processor, which in [H]ard|OCP's testing that would be an i7-4770K. Check out the full review to see how well it can outperform the stock cooler, in both heat and sound management.
"SilverStone's Argon Series AR08 looks to address those building a budget mid-level computer that balances performance and budget. It does however bring some enthusiast features with it like direct contact heatpipes, a 92mm PWM "diamond edged" fan, and noise dampening technologies. "

The turn based strategy and base management of X-COM will survive in Phoenix Point but from what was revealed by Rock, Paper, SHOTGUN you may not survive that long. It is not just the mutated victims of the alien virus you need to be wary of but also your fellow surviving humans as there are several faction with very different and incompatible survival strategies. The mutated enemies will not be broken down into distinct and repetitive races, instead they will evolve as you try to defeat them. Sniper heavy tactics could result in aliens with reinforced front facing armour the next time you deal with them, use grenades and the next wave you face may be resistant to fire. The game sounds very complex but it is not due for release until 2018 so there is plenty of time for them to make this game work. Check out more by following the link.
"One of the most exciting games in Los Angeles this week won’t be featured at press conferences or on the showfloor. Phoenix Point [official site] is the new tactical-strategy hybrid from Julian Gollop, the creator of the original X-COM, and we met yesterday to discuss its procedurally generated alien threats, simulated human factions and much more."

Tagged: GTX1070, nvidia, overclocking
Overclocking the new Pascal GPUs can be accomplished with the EVGA Precision X tool as it allows you to bump up the power, temperature target and fan speed as well as the frequencies for the GPU and memory easily and effectively. [H]ard|OCP set out to push the 1070 as far as it would go with this software in a recent review. The power target can only be increased to 112%, which they implemented along with setting the fan to 100% as this is about the maximum performance, not about peace and quiet. After quite a bit of testing they settled on 2062MHz GPU and 4252MHz RAM clocks as the highest stable frequency this particular card could manage. The results show a card which leaves the TITAN X in the dirt and this card does not even have a custom cooler; we anxiously await the non-Founders Edition releases to see what they can accomplish.
"In our overclocking review of the NVIDIA GeForce GTX 1070 Founders Edition we will see how far we can overclock the GPU and memory and then compare performance with GeForce GTX TITAN X and GeForce GTX 980 Ti. How high will she go? Can the $449 GTX 1070 outperform a $1000 GTX TITAN X? The answer is exciting."

Tagged: google, quantum computing
IBM, D-Wave and Google are the major players in quantum computing research, with each taking a different route towards developing a Universal Turing Machine using qubits; a machine that can perform all the computations of a traditional processor but at speeds exponentially faster. Before the research discussed in this article at Nanotechweb, Google had focused on adiabatic solution which is essentially a quantum computer purpose built to solve a particular problem, not a machine capable of performing any data manipulation problem presented. They have switched tactics have digitized their adiabatic quantum computer to allow for error correction and to allow for non-stoquastic interactions. This should, in theory, allow for scalability thanks to the unique direction the research is taking. The reading is rather heavy, especially if you follow the link to Nature but very interesting if you are curious about new methods of developing quantum computers.
"Bringing together the best of two types of quantum computer for the first time, researchers at Google have created a prototype that combines the architecture of both a universal quantum computer and an analogue quantum computer."

Introduction, Dynamic Write Acceleration, and Packaging
Micron joined Intel in announcing their joint venture production of IMFT 3D NAND just a bit over a year ago. The industry was naturally excited since IMFT has historically enabled relatively efficient production, ultimately resulting in reduced SSD prices over time. I suspect this time things will be no different as IMFT's 3D Flash has been aiming high die capacities since its inception, and I suspect their second generation will *double* per-die capacities while keeping speeds reasonable thanks to a quad-plane design implemented from the start of this endeavor. Of course, I'm getting ahead of myself a bit as there are no consumer products sporting this flash just yet - well not until today at least:
Marketed under Micron's consumer brand Crucial, the MX300 is their first entrant into the consumer space, as well as the first consumer SSD sporting IMFT 3D NAND. Crucial is known for their budget-minded SSDs, and for the MX300 they chose to go with the best cost/GB they could manage with what they had to work with. That meant putting this new 3D NAND into TLC mode. Now there are many TLC haters out there, but remember this is 3D NAND. Samsung's 850 EVO can exceed 500 MB/sec writes to TLC at its 500GB capacity point, and this MX300 is a product that is launching with *only* a 750GB capacity, so its TLC speed should be at least reasonable.
(the return of) Dynamic Write Acceleration
Dynamic Write Acceleration in action during a sequential fill - that last slowest part was my primary concern for the mX300.
TLC is not the only story here because Crucial has included their Dynamic Write Acceleration (DWA) technology into the MX300. This is a tech where the SSD controller is able to dynamically switch flash programming modes of the flash pool, doing so at the block level. This appears to be a feature unique to IMFT flash, as every other 'hybrid' SSD we have tested had a static SLC cache area. DWA's ability to switch flash modes on-the-fly has always fascinated me on paper, but I just haven't been impressed by Micron's previous attempts to implement it. The M600 was a bit all over the place on its write consistency, and that SSD was flipping blocks between SLC and MLC. With the MX300 flipping between SLC and *TLC*, there was a possibility of far more noticeable slow downs in the cases where large writes were taking place and the controller was caught trying to scavenge space in the background.

The new NUC6i5SYK may look like the previous generations but the innards represent a huge step forward. At the base is a Skylake Core i5-6260U which brings with it support for DDR4 and more importantly NVMe SSDs. Connectivity includes Ethernet, 802.11AC Dual Band WiFi, miniDP 1.2 and proper HDMI CEC 1.4b output. The barebones kit will run $380USD, not bad for this type of design. Missing Remote put the new NUC through its paces; check out the results here.
"Updated with an Intel Core i5-6260U with Intel Iris Graphics 540, support for NVMe SSD, and DDR4, the system has the opportunity to fix the shortcomings in the previous generation (cough, CSH). The sleek looks and features will not be as much of a bargain as the plug-in-and-go Intel Pentium based NUC5PGYH. Intel is asking $380/£335 for the barebones kit, but with quite a bit more performance, better networking, and features on tap, it could well be worth the extra dosh."

AMD has just unveiled their entire RX line of graphics cards at E3 2016's PC Gaming Show. It was a fairly short segment, but it had a few interesting points in it. At the end, they also gave another teaser of Summit Ridge, which uses the Zen architecture.
First, Polaris. As we know, the RX 480 was going to bring >5 TFLOPs at a $199 price point. They elaborated that this will apply to the 4GB version, which likely means that another version with more VRAM will be available, and that implies 8GB. Beyond the RX 480, AMD has also announced the RX 470 and RX 460. Little is known about the 470, but they mentioned that the 460 will have a <75W TDP. This is interesting because the PCIe bus provides 75W of power. This implies that it will not require any external power, and thus could be a cheap and powerful (in terms of esports titles) addition to an existing desktop. This is an interesting way to use the power savings of the die shrink to 14nm!
They also showed off a backpack VR rig. They didn't really elaborate, but it's here.
As for Zen? AMD showed the new architecture running DOOM, and added the circle-with-Zen branding to a 3D model of a CPU. Zen will be coming first to the enthusiast category with (up to?) eight cores, two threads per core (16 threads total).
The AMD Radeon RX 480 will launch on June 29th for $199 USD (4GB). None of the other products have a specific release date.

Braven's BRV-XXL is a wee bit bigger than your average portable speaker, 8.2kg (18lbs) and 514x210x241mm (20.25x8.25x9.5") and Techgage conducted some tests to see if it is worth carting around. Part of that weight is the 15,600 mAh battery, giving 12 or more hours of play and happily charging phones as well. As well there are four speakers and a subwoofer in the BRV-XXL, offering significantly more range and volume that a more petite portable speaker. Read on to see if it sounded good enough to offset the encumbrance penalty.
"Braven is no stranger to portable audio, but its latest creation might be its best yet. Can you really have it all in a portable speaker? Let’s find out if the Braven BRV-XXL can allow us to answer “yes”."
