AMD and NVIDIA on the Vive; perfomance data on Raw Data

Subject: Graphics Cards | August 8, 2016 - 05:25 PM |
Tagged: htc vive, amd, nvidia, raw data

Raw Data is an early access game for the HTC Vive, one which requires space to move and which allows the Vive to show off its tracking ability.  [H]ard|OCP wanted to see how the GPUs found in most high end systems would perform in this VR game and so grabbed several AMD and NVIDIA cards to test out.  Benchmarking VR games is not an easy task, instead of raw performance you need to focus on the dropped frames and unstable fps which result in nausea and a less engrossing VR experience.  To that end [H] has played the game numerous times on a variety of GPUs with settings changing throughout to determine the sweet spot for the GPU you are running.  VR offers a new gaming experience and new tests need to be developed to demonstrate performance to those interested in jumping into the new market.  Check out the full review to see what you think of their methodology as well as the raw performance of the cards.

"Both AMD and NVIDIA have had a lot to say about "VR" for a while now. VR is far from mainstream, but we are now seeing some games that are tremendously compelling to play, putting you in middle of the action. Raw Data is one of those, and it is extremely GPU intensive. How do the newest GPUs stack up in Raw Data?"

DIY HiFi; build yourself electrostatic speakers and show them off

Subject: General Tech | August 8, 2016 - 03:38 PM |
Tagged: audio, electrostatic speaker, DIY

Instead of focusing on the troubling security holes reported on today how about you distract yourself by reading up on electrostatic speakers and how to make them yourself.  Electrostatic loudspeakers differ from conventional magnetic speakers as they use the attraction and repulsion of a thin conductive film in an electric field to create sound waves.  This allows the speakers to produce audio with very little distortion and comparatively flat frequency response but also comes with a drawback; half the audio is sent backwards and there is no easy way to reflect it to the front.  Check out the build process and material required to create your own unique high end speakers over at Hack a Day.

"Any thin flexible plastic film can make a noise in an electrostatic speaker, but for best performance the thinner your film, the better. 5 micron thick Mylar seems to be the preferred choice."

"Unlike the two previous AMD GPUs released under the Polaris branding recently, RX 460 is very much a mainstream part that's aimed at buyers who are taking their first real steps into PC gaming. RX 460 uses a distinct, smaller die and is to be priced from £99. As usual, let's fire up the comparison specification table and dissect the latest offering from AMD."

Sapphire's Custom Cooled Nitro+ RX 470 Available Now

Subject: Graphics Cards | August 6, 2016 - 02:24 PM |
Tagged: sapphire, rx 470, polaris 10, dual x, amd

Following the official launch of AMD's Radeon RX 470 GPU, Sapphire has unleashed its own custom graphics card with the Nitro+ RX 470 in 4GB and 8GB factory overclocked versions. Surprisingly, the new cards are up for purchase now at various retailers at $210 for the 4GB model and $240 for the 8GB model (more on that in a bit).

The new Nitro+ RX 470 uses the same board and cooler design as the previously announced Nitro+ RX 480 which is a good thing both for Sapphire (less R&D cost) and for consumers as they get a rather beefy cooler that should allow them to push the RX 470 clocks quite a bit. The card uses the same Dual X cooler with two 95mm quick connect fans, three nickel plated copper heatpipes, and an aluminum fin stack. The card features the same black fan shroud and black and silver colored backplate. Out of the box this cooler should keep the RX 470 GPU running cooler and quieter than the RX 480, but it should also enable users to get higher clocks out of the smaller GPU (less cores means less heat and more overclocking headroom assuming you get a good chip from the silicon lottery).

Sapphire Nitro+ RX 470.jpg

Sapphire is using Black Diamond 4 chokes and a 4+1 power phase design that is driven by a single 8-pin PCI-E power connector (and up to 75W from the motherboard slot). This mirrors the design of its RX 480 sibling.

Display outputs include a single DVI, two HDMI 2.0b, and two DisplayPort 1.4 ports.

The chart below outlines the comparison between the Nitro+ RX 470 cards, RX 470 reference specifications, and the RX 480.

 

Nitro+ RX 470 4GB

Nitro+ RX 470 8GB RX 470 Reference RX 480
Stream Processors 2048 2048 2048 2304
Compute Units 32 32 32 36
TMUs 128 128 128 144
ROPs 32 32 32 32
GPU Clock (Base) 1143 MHz 1121 MHz 926 MHz 1120 MHz
GPU Clock (Boost) 1260 MHz 1260 MHz 1206 MHz 1266 MHz
Memory 4GB GDDR5 @ 7 GHz 8GB GDDR5 @ 8 GHz 4 or 8 GB GDDR5 @ 6.6 GHz 4 or 8 GB GDDR5 @ up to 8 GHz
Memory Bus 256-bit 256-bit 256-bit 256-bit
Memory Bandwidth 224 GB/s 256 GB/s 211 GB/s 256 GB/s
TDP <225W <225W 120W 150W
GPU Polaris 10 Polaris 10 Polaris 10 Polaris 10
Price $210 $240 $180+ $200+ ($240+ for 8GB)

The RX 470 GPU is only slightly cut down from RX 480 in that it features four fewer CUs though the processor maintains the same number of ROP units and the same 256-bit memory bus. Reference clocks are 926 MHz base and 1206 MHz boost. Memory can be up to 8GB of GDDR5 with reference memory clocks of 6.6 GHz (effective). Sapphire has overclocked both the GPU and memory with the NItro+ series. The Nitro+ RX 470 with 4GB of GDDR5 is clocked at 1143 MHz base, 1260 MHz boost, and 7 GHz memory while the 8GB version has a lower base clock of 1121 but a higher memory clock of 8 GHz.

The 8GB model having a lower base overclock is a bit strange to me, but at least they are rated at the same boost clock. These specifications are very close to the RX 480 actually and with a bit of user overclocking beyond the factory overclock you could get even closer to the performance of it.

The problem with this RX 470 that gets so close to the RX 480 though is that the price is also very close to reference RX 480s! The Sapphire Nitro+ RX 470 4GB is priced at $209.99 while the Nitro+ RX 470 8GB is $239.99.

These prices put the card well into RX 480 territory though not quite up to the MSRPs of factory overclocked RX 480s (e.g. Sapphire's own Nitro+ RX 480 is $219 and $269 for 4GB and 8GB respectively). The company has a nice looking (and hopefully performing) RX 470, but it is going to be tough to choose this card over a RX 480 that has more shaders and TMUs. One advantage though is that this is a card that will just work without having to manually overclock (though where is the fun in that? heh) and it is actually available right now unlike the slew of RX 480 cards that have been launched but are consistently out of stock everywhere! If you simply can't wait for a RX 480, this might not be a bad option.

EDIT: Of course the 8GB model goes out of stock at Newegg as I write this and Amazon's prices are higher than MSRP! hah.

Computer Base (German language, Google-translated link here) has rounded up five CPU water blocks to see which might offer the highest performance on their Intel Core i7 3960X-equipped testbed.

The tested water blocks include:

  • Alphacool NexXxos XP3 Light V.2
  • Phobya UC-2 LT
  • Raijintek CWB-C1
  • Heatkiller IV Pro Pure Copper
  • XSPC Raystorm Pro

The review offers an thorough look at the design of each water block, as well as an interesting look at the effects of flow-rate on performance:

"The test has been shown that with increasing flow rate decreases the temperature difference of the water before and after heat sinks. However, the question arises whether a higher flow also has a positive effect on the cooling performance itself. A negative effect of increasing flow as well: Most pumps are unthrottled very loud to work, so that a reduced pump capacity is useful for a silent water cooling."

Microsoft Publishes HLSL Shader Model 6.0 MSDN Docs

Subject: Graphics Cards | August 2, 2016 - 07:37 AM |
Tagged: windows 10, vulkan, microsoft, DirectX 12

Update (August 3rd @ 4:30pm): Turns out Khronos Group announced at SIGGRAPH that Subgroup Instructions have been recently added to SPIR-V (skip video to 21:30), and are a "top priority" for "Vulkan Next". Some (like WaveBallot) are already ARB (multi-vendor) OpenGL extensions, too.

Original post below:

DirectX 12's shading language will receive some new functionality with the new Shader Model 6.0. According to their GDC talks, it is looking like it will be structured similar to SPIR-V in how it's compiled and ingested. Code will be compiled and optimized as an LLVM-style bytecode, which the driver will accept and execute on the GPU. This could make it easy to write DX12-compatible shader code in other languages, like C++, which is a direction that Vulkan is heading, but Microsoft hasn't seemed to announce that yet.

microsoft-2015-directx12-logo.jpg

This news shows a bit more of the nitty gritty details. It looks like they added 16-bit signed (short) and unsigned (ushort) integers, which might provide a performance improvement on certain architectures (although I'm not sure that it's new and/or GPUs exist the natively operate upon them) because they operate on half of the data as a standard, 32-bit integer. They have also added more functionality, to both the pixel and compute shaders, to operate in multiple threads, called lanes, similar to OpenCL. This should allow algorithms to work more efficiently in blocks of pixels, rather than needing to use one of a handful of fixed function calls (ex: partial derivates ddx and ddy) to see outside their thread.

When will this land? No idea, but it is conspicuously close to the Anniversary Update. It has been added to Feature Level 12.0, so its GPU support should be pretty good. Also, Vulkan exists, doing its thing. Not sure how these functions overlap with SPIR-V's feature set, but, since SPIR was original for OpenCL, it could be just sitting there for all I know.

DOTA 2: The International 6 Begins Monday

Tagged: valve, pc gaming, esports, DOTA 2

Every year, Valve hosts a giant gaming event called “The International”. While the prize pool is still being increased through purchases of the The International 2016 Battle Pass DLC bundle, it currently rests just below $19.4 million USD. The way previous years worked is that about a third went to first place, and the rest trickled down. Keep in mind that DOTA 2 is a team sport, though, so winnings don't all go to a single person.

valve-2016-the-international-6-logo.png

Anywho, it will be a five-day event broadcasted on Twitch, Steam Broadcasting, WatchESPN, and YouTube. Owners of a SteamVR-compatible headset will also be able to view the broadcast in VR (which isn't just for The International, but this is the first The International to support it). It's not just projecting you into the stadium, either; it gives you a command center to see stats around you, or you can jump down into the map to see the battle around you “human scale”.

The International 6 begins on Monday.

Sapphire Will Release Custom Radeon RX 460 Nitro OC Graphics Card

Subject: Graphics Cards | August 2, 2016 - 03:50 AM |
Tagged: sapphire, rx 460, polaris 11, nitro, amd

AMD and its board partners will officially launch the first Polaris 11 GPU and the Radeon RX 460 graphics cards based around that processor on August 8th. Fortunately Videocardz.com got a hold of an image that shows off Sapphire's take on the RX 460 in the form of a factory overclocked and custom cooled RX460 Nitro OC. This gives us a hint at the kinds of cards we can expect and it appears to be good news for budget gamers as it suggests that there will be several options around this firm $100 price point that are a bit more than the bare necessities.

In the case of Sapphire's RX 460 Nitro OC, it uses a custom dual fan cooler with two copper heatpipes, an aluminum fin stack (that is much larger than reference), and two 90mm fans. Display IO includes one DVI, one HDMI, and one DisplayPort. The card itself uses a physical PCI-E x16 connector that is electrically PCI-E 3.0 x8. The x8 connection will be more than enough for this GPU though it also enables partners to cut costs.

Sapphire Nitro RX 460 OC.jpg

Clockspeeds are not yet known, but the Polaris 11 GPU (896 cores, 56 TMUs, 16 ROPs) will be paired with 4GB GDDR5 memory.

It is encouraging to me to see custom cards at this price point out of the gate with the full 4GB of memory (AMD allows 2GB or 4GB versions). Gamers that simply can't justify spending much more than a hundred dollars on a GPU should have ample options to choose from and I am looking forward to seeing what all the partners have to offer. 

Are you looking at Polaris 11 and the RX 460 for a super budget gaming build? What do you think about Sapphire's card with the company's custom cooler?

Samsung PM1633a: 15.36TB SSD for $10,000 USD

Allyn first mentioned this device last year, but they're apparently now shipping for a whopping $10,000 USD. To refresh, the PM1633a is an SSD from Samsung that packs 15.36TB into a 2.5-inch form factor. According to Samsung, it does this by stacking 16 dies, each containing 48 layers of flash cells, into a 512GB package. It's unclear how many packages are installed in the device, because we don't know how much over-provisioning Samsung provides, but the advertised capacity equates to exactly 30 packages. Update @ 11:30pm: Turns out I was staring right at it in the old press release. The drive has 32 packages, so 16384 GB, once you account for over-provisioning.

Down at CDW, they are selling them for $10,311.99 USD with the option to lease for $321.73 / month. That's only 2.1c/GB... per month... for probably three whole years. No Ryan, that doesn't count. The warranty period doesn't seem to be listed, but Samsung will cover up to 15.36TB per day in writes. I mean, we knew it would be expensive, given its size and performance. At least it's only ~65c/GB.

He spends the first half of the video with a discussion of previous videos, an overview of the industry and its split between vendors and manufacturers, and an explanation of various components including the difference between CPU and GPU plates. The second half of the video disassembles the cooler, talking about it as he goes.

The disassembly begins at ~9 minutes.

The availability of closed-loop coolers introduced me to water cooling. While I could be very careful to do everything right, I just don't trust myself to assemble a liquid-filled (non-conducting or otherwise) component that close to electronics. Part of that could be attributed to my childhood, where a dead PC meant no computer for x number of weeks, or months, because we could barely afford one at all. An assembled (and warrantied) cooler, though, while still intimidating when the tubes get even slightly torqued, is clearly designed to go in hassle-free and remain working without maintenance. That's a good part of why, while it's pretty obvious what is inside these units, seeing it first-hand is fascinating (at least for me).

Rumor: GTX 980 and GTX 960 Lawsuits???

Update @ 9:45pm: I heard that some AMD users were notified about their R9 purchase as well, calling it simply "R9". Since I didn't see concrete proof, I omit it from the post in case it was a hoax (as the story is still developing). I have since been notified of a tweet with an email screenshot.

Original post below:

Apparently, Newegg is informing customers that NVIDIA has settled a class action lawsuit with customers of the GeForce GTX 960 and GTX 980 cards, along with the GTX 970. It's currently unclear whether this is an error, or whether this is one of the sibling class action lawsuits that were apparently bundled together with the GTX 970 one. Users on the NVIDIA Reddit are claiming that it has to do with DirectX 12 feature level support, although that seems like knee-jerk confirmation bias to me.

Regardless, if you purchased a GeForce 900-series graphics card from Newegg, maybe even including the 980 Ti, then you should check your email. You might have a settlement en-route.

That's all we know at this point, though. Thanks to our readers for pointing this out.

Windows 10 Version 1607 Changes Driver Signing Policy

Remember, folks, that “the road to Hell is paved with good intentions”. Microsoft has been trying to shed their stigma as a giant source of malware, but all solutions have side-effects, and those side-effects can have damaging consequences. When you believe that you or someone else is doing good, that is when you should be extra cautious, not less. It's a source of complacency.

With tomorrow's Windows 10 Anniversary Update, Microsoft will require kernel-mode drivers to be signed by them on systems with Secure Boot enabled. This change will not affect PCs that have been upgraded from a previous version of Windows, including Windows 10 1507 and Windows 10 1511. That said, this could be a concern for those (like me) who are planning to clean install soon.

To me, this doesn't look like it will be that big of a deal. Hobbyists should be able to manage with either disabling Secure Boot, if their system allows it, or by fitting their driver around the user-mode framework. It might cause an issue with hotfix graphics drivers, though, which are pushed out before getting signed by Microsoft.

Also, if Microsoft changes their driver signing policy in the future, then this is could be (Update @ 7:30pm ET: original verbage was a little too strong) huge leverage against anyone attempting to circumvent it (such as implementing a graphics API that outperforms whatever DirectX version they have at the time -- see how Vulkan is not allowed on MacOSX). Even if you trust Microsoft now, you need to think about what Microsoft in 10+ years can do if they choose to.
