[H]ard|OCP took a look into the effect on performance the gigantic high resolution texture pack has on system performance in their latest article.  For those who want the answer immediately, the largest amount of VRAM they saw utilized was a hair over 5GB, in most cases more than double the usage that the default textures use.  This certainly suggests that those with 4GB cards should reconsider installing the texture pack and that a 6GB card shouldn't see performance impacts.  As for the performance deltas, well we can't provide spoilers for their entire review!

Vulkan is not extinct, in fact it might be about to erupt

The open source API, Vulkan, just received a big birthday present from Intel as they added official support on their Skylake and Kaby Lake CPUs under Windows 10.  We have seen adoption of this API from a number of game engine designers, Unreal Engine and Unity have both embraced it, the latest DOOM release was updated to support Vulkan and there is even a Nintendo 64 renderer which runs on it.  Ars Technica points out that both AMD and NVIDIA have been supporting this API for a while and that we can expect to see Android implementations of this close to the metal solution in the near future.

"After months in beta, Intel's latest driver for its integrated GPUs (version 15.45.14.4590) adds support for the low-overhead Vulkan API for recent GPUs running in Windows 10. The driver supports HD and Iris 500- and 600-series GPUs, the ones that ship with 6th- and 7th-generation Skylake and Kaby Lake processors."

NVIDIA Releases GeForce 378.66 Drivers with New Features

Subject: Graphics Cards | February 14, 2017 - 09:29 PM |
Tagged: opencl 2.0, opencl, nvidia, graphics drivers

While the headline of the GeForce 378.66 graphics driver release is support for For Honor, Halo Wars 2, and Sniper Elite 4, NVIDIA has snuck something major into the 378 branch: OpenCL 2.0 is now available for evaluation. (I double-checked 378.49 release notes and confirmed that this is new to 378.66.)

nvidia-geforce.png

OpenCL 2.0 support is not complete yet, but at least NVIDIA is now clearly intending to roll it out to end-users. Among other benefits, OpenCL 2.0 allows kernels (think shaders) to, without the host intervening, enqueue work onto the GPU. This saves one (or more) round-trips to the CPU, especially in workloads where you don’t know which kernel will be required until you see the results of the previous run, like recursive sorting algorithms.

So yeah, that’s good, albeit you usually see big changes at the start of version branches.

Another major addition is Video SDK 8.0. This version allows 10- and 12-bit decoding of VP9 and HEVC video. So... yeah. Applications that want to accelerate video encoding or decoding can now hook up to NVIDIA GPUs for more codecs and features.

NVIDIA’s GeForce 378.66 drivers are available now.

AMD Releases Radeon Software Crimson ReLive 17.2.1

Subject: Graphics Cards | February 14, 2017 - 05:57 PM |
Tagged: amd, graphics drivers

Just in time for For Honor and Sniper Elite 4, AMD has released a new set of graphics drivers, Radeon Software Crimson ReLive 17.2.1, that target these games. The performance improvements that they quote are in the 4-5% range, when compared to their previous driver on the RX 480, which would be equivalent to saving a whole millisecond per frame at 60 FPS. (This is just for mathematical reference; I don’t know what performance users should expect with an RX 480.)

amd-2016-crimson-relive-logo.png

Beyond driver overhead improvements, you will now be able to utilize multiple GPUs in CrossFire (for DirectX 11) on both titles.

Also, several issues have been fixed with this version. If you have a FreeSync monitor, and some games fail to activate variable refresh mode, then this driver might solve this problem for you. Scrubbing through some videos (DXVA H.264) should no longer cause visible corruption. A couple applications, like GRID and DayZ, should no longer crash under certain situations. You get the idea.

If you have an AMD GPU on Windows, pick up these drivers from their support page.

If there is one thing we are short on, it is incompatible videoconferencing applications to use and support.  Obviously this is why Amazon purchased Biba and has now leaped into the fray to provide Chime, a truly unique service which will transmit your voice and video over the internet in something called a conference.  Sarcasm aside, Amazon Web Services have proven that they provide a solid set of services, which will be the backbone of the new app.  Those who have struggled with Adobe's offering or tried to have a meeting during many of the outage periods which plague various other providers might want to take a look.

The basic service is free, Plus allows screen sharing and access to corporate directories for $2.50 per user a month and the Pro version runs $15, allowing up to 100 people in a video call as well as the all important personalized URL.  Pop by Slashdot if you so desire.

Much like HDR displays and VR, it can be hard to show what a tempered glass case looks like with just a few pictures but that is exactly what eTeknix set out to do in this review.  The case is quite large, e-ATX motherboards are supported and the three fans at the front of the case are all 140mm as is the one in the back, with room for three more if you so desire.  There is also an integral fan controller, with the three modes easily accessible on the top of the case. The PSU is hidden under a shroud, SSDs are mounted on the back of the case and decent cable management ensure that your see-through system is worth looking at.

"There’s a big trend in the chassis market this last year or so, as more and more brands shift from plastic side panel windows, to huge chunks of tempered glass. If you really care about having a system that looks like a premium quality product, and having a great way to show off your new build and hardware, then tempered glass is the way to go."

A Closer Look at Intel's Optane SSD DC P4800X Enterprise SSD Performance

Subject: Storage | February 10, 2017 - 04:22 PM |
Tagged: Optane, XPoint, P4800X, 375GB

Over the past few hours, we have seen another Intel Optane SSD leak rise to the surface. While we previously saw a roadmap and specs for a mobile storage accelerator platform, this time we have some specs for an enterprise part:

optane-leak.png

The specs are certainly impressive. While they don't match the maximum theoretical figures we heard at the initial XPoint announcement, we do see an endurance rating of 30 DWPD (drive writes per day), which is impressive given competing NAND products typically run in the single digits for that same metric. The 12.3 PetaBytes Written (PBW) rating is even more impressive given the capacity point that rating is based on is only 375GB (compare with 2000+ GB of enterprise parts that still do not match that figure).

Now I could rattle off the rest of the performance figures, but those are just numbers, and fortunately we have ways of showing these specs in a more practical manner:

rnd.png

Assuming the P4800X at least meets its stated specifications (very likely given Intel's track record there), and also with the understanding that XPoint products typically reach their maximum IOPS at Queue Depths far below 16, we can compare the theoretical figures for this new Optane part to the measured results from the two most recent NAND-based enterprise launches. To say the random performance makes leaves those parts in the dust is an understatement. 500,000+ IOPS is one thing, but doing so at lower QD's (where actual real-world enterprise usage actually sits) just makes this more of an embarrassment to NAND parts. The added latency of NAND translates to far higher/impractical QD's (256+) to reach their maximum ratings.

server workload QD.png

Intel research on typical Queue Depths seen in various enterprise workloads. Note that a lower latency device running the same workload will further 'shallow the queue', meaning even lower QD.

Another big deal in the enterprise is QoS. High IOPS and low latency are great, but where the rubber meets the road here is consistency. Enterprise tests measure this in varying degrees of "9's", which exponentially approach 100% of all IO latencies seen during a test run. The plot method used below acts to 'zoom in' on the tail latency of these devices. While a given SSD might have very good average latency and IOPS, it's the outliers that lead to timeouts in time-critical applications, making tail latency an important item to detail.

qos-r.png

qos-w.png

I've taken some liberties in my approximations below the 99.999% point in these plots. Note that the spec sheet does claim typical latencies "<10us", which falls off to the left of the scale. Not only are the potential latencies great with Optane, the claimed consistency gains are even better. Translating what you see above, the highest percentile latency IOs of the P4800X should be 10x-100x (log scale above) faster than Intel's own SSD DC P3520. The P4800X should also easily beat the Micron 9100 MAX, even despite its IOPS being 5x higher than the P3520 at QD16. These lower latencies also mean we will have to add another decade to the low end of our Latency Percentile plots when we test these new products.

Well, there you have it. The cost/GB will naturally be higher for these new XPoint parts, but the expected performance improvements should make it well worth the additional cost for those who need blistering fast yet persistent storage.

NVIDIA Announces Q4 2017 Results

Subject: Editorial | February 9, 2017 - 06:59 PM |
Tagged: TSMC, Samsung, Results, quadro, Q4, nvidia, Intel, geforce, Drive PX2, amd, 2017, 2016

It is most definitely quarterly reports time for our favorite tech firms.  NVIDIA’s is unique with their fiscal vs. calendar year as compared to how AMD and Intel report.  This has to do when NVIDIA had their first public offering and set the fiscal quarters ahead quite a few months from the actual calendar.  So when NVIDIA announces Q4 2017, it is actually reflecting the Q4 period in 2016.  Clear as mud?

Semantics aside, NVIDIA had a record quarter.  Gross revenue was an impressive $2.173 billion US.  This is up slightly more than $700 million from the previous Q4.  NVIDIA has shown amazing growth during this time attributed to several factors.  Net income (GAAP) is at $655 million.  This again is a tremendous amount of profit for a company that came in just over $2 billion in revenue.  We can compare this to AMD’s results two weeks ago that hit $1.11 billion in revenue and a loss of $51 million for the quarter.  Consider that AMD provides CPUs, chipsets, and GPUs to the market and is the #2 x86 manufacturer in the world.

NVLogo_2D_H.jpg

The yearly results were just as impressive.  FY 2017 featured record revenue and net income.  Revenue was $6.91 billion as compare to FY 2016 at $5 billion.  Net income for the year was $1.666 billion with comparison to $614 million for FY 2016.  The growth for the entire year is astounding, and certainly the company had not seen an expansion like this since the early 2000s.

The core strength of the company continues to be gaming.  Gaming GPUs and products provided $1.348 billion in revenue by themselves.  Since the manufacturing industry was unable to provide a usable 20 nm planar product for large, complex ASICs companies such as NVIDIA and AMD were forced to innovate in design to create new products with greater feature sets and performance, all the while still using the same 28 nm process as previous products.  Typically process shrinks accounted for the majority of improvements (more transistors packed into a smaller area with corresponding switching speed increases).  Many users kept cards that were several years old due to there not being a huge impetus to upgrade.  With the arrival of the 14 nm and 16 nm processes from Samsung and TSMC respectively, users suddenly had a very significant reason to upgrade.  NVIDIA was able to address the entire market from high to low with their latest GTX 10x0 series of products.  AMD on the other hand only had new products that hit the midrange and budget markets.

NV-Q4-2014.jpg

The next biggest area for NVIDIA is that of the datacenter.  This has seen tremendous growth as compared to the other markets (except of course gaming) that NVIDIA covers.  It has gone from around $97 million in Q4 2016 up to $296 million this last quarter.  Tripling revenue in any one area is rare.  Gaming “only” about doubled during this same time period.  Deep learning and AI are two areas that required this type of compute power and NVIDIA was able to deliver a comprehensive software stack, as well as strategic partnerships that provided turnkey solutions for end users.

After datacenter we still have the visualization market based on the Quadro products.  This area has not seen the dramatic growth as other aspects of the company, but it remains a solid foundation and a good money maker for the firm.  The Quadro products continue to be improved upon and software support grows.

One area that promises to really explode in the next three to four years is the automotive sector.  The Drive PX2 system is being integrated into a variety of cars and NVIDIA is focused on providing a solid and feature packed solution for manufacturers.  Auto-pilot and “co-pilot” modes will become more and more important in upcoming models and should reach wide availability by 2020, if not a little sooner.  NVIDIA is working with some of the biggest names in the industry from both automakers and parts suppliers.  BMW should release a fully automated driving system later this year with their i8 series.  Audi also has higher end cars in the works that will utilize NVIDIA hardware and fully automated operation.  If NVIDIA continues to expand here, eventually it could become as significant a source of income as gaming is today.

There was one bit of bad news from the company.  Their OEM & IP division has seen several drops over the past several quarters.  NVIDIA announced that the IP licensing to Intel would be discontinued this quarter and would not be renewed.  We know that AMD has entered into an agreement with Intel to provide graphics IP to the company in future parts and to cover Intel in potential licensing litigation.  This was a fair amount of money per quarter for NVIDIA, but their other divisions more than made up for the loss of this particular income.

NVIDIA certainly seems to be hitting on all cylinders and is growing into markets that previously were unavailable as of five to ten years ago.  They are spreading out their financial base so as to avoid boom and bust cycles of any one industry.  Next quarter NVIDIA expects revenue to be down seasonally into the $1.9 billion range.  Even though that number is down, it would still represent the 3rd highest quarterly revenue.

Blender Foundation Releases 2.78b... for Performance!

Subject: General Tech | February 9, 2017 - 05:03 PM |
Tagged: Blender

It has been a few months since the release of 2.78, and the Blender Foundation has been sitting on a bunch of performance enhancements in that time. Since 2.79 is still a couple of months off, they decided to “cherry pick” a bunch of them back into the 2.78 branch and push out an update to it. Most of these updates are things like multi-threading their shader compiler for Cycles, speeding up motion blur in Cycles, and reducing “fireflies” in Cycles renders, which indirectly helps performance by requiring less light samples to average out the noise.

blender-2016-278logo.jpg

I tried running two frames from different scenes of my upcoming PC enthusiast explanation video. While they’re fairly light, motion graphics sequences, they both use a little bit of motion blur (~half of a 60 Hz frame of integration) and one of the two frames is in the middle of three objects with volumetric absorption that are moving quite fast.

0580.png

The "easier" scene to render.

When disabling my GTX 670, and only using my GTX 1080, the easier scene went from 9.96s in 2.78a to 9.99s in 2.78b. The harsher scene, with volumetric absorption and a big streak of motion blur, went from 36.4s in 2.78a to 36.31s in 2.78b. My typical render settings include a fairly high sample count, though, so it’s possible that I could get away with less and save time that way.

0605.png

The "harsher" scene to render.

Blender is currently working on Agent 327, which is an upcoming animated feature film. Typically, these movies guide development of the project, so it makes sense that my little one-person motion graphics won’t have the complexity to show the huge optimizations that they’re targeting. Also, I had a lot of other programs running, which is known to make a significant difference in render time, although they were doing the same things between runs. No browser tabs were opened or closed, the same videos were running on other monitors while 2.78a and 2.78b were working, etc. But yeah, it's not a bulletproof benchmark by any means.

Also, some of the optimizations solve bugs with Intel’s CPU implementation as well as increase the use of SSE 4.1+ and AVX2. Unfortunately for AMD, these were pushed up right before the launch of Ryzen, and Blender with Cycles has been one of their go-to benchmarks for multi-threaded performance. While this won’t hurt AMD any more than typical version-to-version variations, it should give a last-minute boost to their competitors on AMD’s home turf.

Blender 2.78b is available today, free as always, at their website.

Have you ever noticed how many drivers on your system are dated June 21st, 2006?  If not, pop open device manager and take a look at some of your devices which don't use a driver directly from the manufacturer.  Slashdot posted a link to the inimitable Raymond Chen who explains exactly why so many of your drivers bear that date.  The short version is that this is a workaround which prevents newer Microsoft drivers from overwriting manufacturer's drivers by ensuring the date stamp on the Microsoft driver will never have a more recent date.  This is especially important for laptop users as even the simple chipset drivers will be supplied by the manufacturer.  For instance this processor is old, but not that old!

"When the system looks for a driver to use for a particular piece of hardware, it ranks them according to various criteria. If a driver provides a perfect match to the hardware ID, then it becomes a top candidate. And if more than one driver provides a perfect match, then the one with the most recent timestamp is chosen."

WebKit Proposal for WebGPU

Subject: General Tech | February 8, 2017 - 10:46 PM |
Tagged: webkit, webgpu, metal, vulkan, webgl

Apple’s WebKit team has just announced their proposal for WebGPU, which competes with WebGL to provide graphics and GPU compute to websites. Being from Apple, it is based on the Metal API, so it has a lot of potential, especially as a Web graphics API.

Okay, so I have mixed feelings about this announcement.

apple-2017-webkit-logo.png

First, and most concerning, is that Apple has attempted to legally block open standards in the past. For instance, when The Khronos Group created WebCL based on OpenCL, which Apple owns the trademark and several patents to, Apple shut the door on extending their licensing agreement to the new standard. If the W3C considers Apple’s proposal, they should be really careful about what legal control they allow Apple to retain.

From a functionality standpoint, this is very interesting, though. With the aforementioned death of WebCL, as well as the sluggish progress of WebGL Compute Shaders, there’s a lot of room to use one (or more) GPUs in a system for high-end compute tasks. Even if you are not interested in gaming on a web browser, although many people are, especially if you count the market that Adobe Flash dominated for the last ten years, you might want to GPU-accelerate photo and video tasks. Having an API that allows for this would be very helpful going forward, although, as stated, others are working on it, like The Khronos Group with WebGL compute shaders. On the other-other hand, an API that allows explicit multi-GPU would be even more interesting.

Further, it sounds like they’re even intending to ingest byte-code, like what DirectX 12 and Vulkan are doing with DXIL and SPIR-V, respectively, but it currently accepts shader code as a string and compiles it in the driver. This is interesting from a security standpoint, because it obfuscates what GPU-executed code consists of, but that’s up to the graphics and browser vendors to figure out... for now.

So when will we see it? No idea! There’s an experimental WebKit patch, which requires the Metal API, and an API proposal... a couple blog posts... a tweet or two... and that’s about it.

So what do you think? Does the API sound interesting? Does Apple’s involvement scare you? Or does getting scared about Apple’s involvement annoy you? Comment away! : D

AMD Details Zen at ISSCC

Subject: Processors | February 8, 2017 - 09:38 PM |
Tagged: Zen, Skylake, Samsung, ryzen, kaby lake, ISSCC, Intel, GLOBALFOUNDRIES, amd, AM4, 14 nm FinFET

Yesterday EE Times posted some interesting information that they had gleaned at ISSCC.  AMD released a paper describing the design process and advances they were able to achieve with the Zen architecture manufactured on Samsung’s/GF’s 14nm FinFETT process.  AMD went over some of the basic measurements at the transistor scale and how it compares to what Intel currently has on their latest 14nm process.

icon.jpg

The first thing that jumps out is that AMD claimes that their 4 core/8 thread x86 core is about 10% smaller than what Intel has with one of their latest CPUs.  We assume it is either Kaby Lake or Skylake.  AMD did not exactly go over exactly what they were counting when looking at the cores because there are some significant differences between the two architectures.  We are not sure if that 44mm sq. figure includes the L3 cache or the L2 caches.  My guess is that it probably includes L2 cache but not L3.  I could be easily wrong here.

Going down the table we see that AMD and Samsung/GF are able to get their SRAM sizes down smaller than what Intel is able to do.  AMD has double the amount of L2 cache per core, but it is only about 60% larger than Intel’s 256 KB L2.  AMD also has a much smaller L3 cache as well than Intel.  Both are 8 MB units but AMD comes in at 16 mm sq. while Intel is at 19.1 mm sq.  There will be differences in how AMD and Intel set up these caches, and until we see L3 performance comparisons we cannot assume too much.

Zen-comparison.png

In some of the basic measurements of the different processes we see that Intel has advantages throughout.  This is not surprising as Intel has been well known to push process technology beyond what others are able to do.  In theory their products will have denser logic throughout, including the SRAM cells.  When looking at this information we wonder how AMD has been able to make their cores and caches smaller.  Part of that is due to the likely setup of cache control and access.

One of the most likely culprits of this smaller size is that the less advanced FPU/SSE/AVX units that AMD has in Zen.  They support AVX-256, but it has to be done in double the cycles.  They can do single cycle AVX-128, but Intel’s throughput is much higher than what AMD can achieve.  AVX is not the end-all, be-all but it is gaining in importance in high performance computing and editing applications.  David Kanter in his article covering the architecture explicitly said that AMD made this decision to lower the die size and power constraints for this product.

Ryzen will undoubtedly be a pretty large chip overall once both modules and 16 MB of L3 cache are put together.  My guess would be in the 220 mm sq. range, but again that is only a guess once all is said and done (northbridge, southbridge, PCI-E controllers, etc.).  What is perhaps most interesting of it all is that AMD has a part that on the surface is very close to the Broadwell-E based Intel i7 chips.  The i7-6900K runs at 3.2 to 3.7 GHz, features 8 cores and 16 threads, and around 20 MB of L2/L3 cache.  AMD’s top end looks to run at 3.6 GHz, features the same number of cores and threads, and has 20 MB of L2/L3 cache.  The Intel part is rated at 140 watts TDP while the AMD part will have a max of 95 watts TDP.

If Ryzen is truly competitive in this top end space (with a price to undercut Intel, yet not destroy their own margins) then AMD is going to be in a good position for the rest of this year.  We will find out exactly what is coming our way next month, but all indications point to Ryzen being competitive in overall performance while being able to undercut Intel in TDPs for comparable cores/threads.  We are counting down the days...

In my case, I needed to hold the on button a few times to get the phone to boot into the second stage of installation, but ZTE mentions it in the pre-install notes, so that’s good. Then, when the phone moved on to the new lock screen, my fingerprint reader didn’t work until after I typed in the lock screen password. I’m not sure why the phone didn’t accept the fingerprint reader until after I successfully logged in, especially since it used the fingerprints on file from Android 6.0, I didn’t need to set it up again, but it’s a small inconvenience. Just don’t perform the update if you can’t access your password manager and you don’t remember the unlock code off the top of your head.

While I don’t have a Daydream VR headset, I’ll probably pick one up soon and give it a test. The Daydream app is installed on the device, though, so you can finally enjoy Android-based VR content if you pick one up.

If your phone hasn’t alerted you yet, find your unlock password and check for updates in the settings app.

inXile have been very busy recently, doing a stellar job at resurrecting Wasteland into a new, modern RPG which is soon to see its third incarnation released.  The long anticipated Torment: Tides of Numenara arrives at the end of this month, the beta has been a tantalizing taste as was the YouTube 'choose your own adventure' teaser.  There is another project they have been working on, bringing the old Bard's Tale gaming into the modern era.  A trailer showing in-game footage, including combat has just been release which you can see over at Rock, Paper, SHOTGUN.  It certainly doesn't look like the Bard's Tale of old!

"On the game HUD, you can see your party occupying 2 rows of 4 spaces each. Enemies will line up on the opposite grid with the same number of slots. The exact positioning of enemies, as well as your own party, will determine which attacks can land, and which will swing wild past their mark."

Jump into Kaby Lake naked

[H]ard|OCP followed up their series on replacing the TIM underneath the heatspreader on Kaby Lake processors with another series depicting the i5-7600K in the buff.  They removed the heatspreader completely and tried watercooling the die directly.  As you can see in the video this requires more work than you might immediately assume, it was not simply shimming which was involved, some of the socket on the motherboard needed to be trimmed with a knife in order to get the waterblock to sit directly on the core.  In the end the results were somewhat depressing, the risks involved are high and the benefits almost non-existent.  If you are willing to risk it, replacing the TIM and reattaching the heatspreader is a far better choice.

"After our recent experiments with delidding and relidding our 7700K and 7600K to see if we could get better operating temperatures, we decided it was time to go topless! Popping the top on your CPU is one thing, and getting it to work in the current processor socket is another. Get out your pocket knife, we are going to have to make some cuts."

FreeSync 2 - The Adaptification!

TechARP published a video of their interview with AMD's David Glen and Syed Hussain in which they discussed what to expect from FreeSync 2.  They also listed some key points for those who do not wish to watch the full video; either can be found right here.  The question on most people's minds is answered immediately, this will not be a Vega only product and if your GPU supports the current version it will support the sequel.  We will not see support for it until a new driver is released, then again we also await new monitors to hit the market as well so it is hard to be upset at AMD for the delay.
