Linux support from AMD seems to be improving, as it has been on Windows. We'll be combining two separate, tiny stories into one, so bear with us. The first is from Fudzilla, and it states that AMD has AMDGPU-PRO 16.30 drivers for the RX 480 out on day one. It's nice to see that their Radeon driver initiative applies to Linux, too.
That brings us to the second story, this one from Phoronix. One Windows, the Crimson 16.7.1 drivers will include a fix for the RX 480 power issues (which we will obviously test of course). Michael Larabel was apparently talking with AMD's Linux team, and it seems likely that this update will roll into the Linux driver as well. They "are still investigating", of course, but it is apparently on their radar.

In the next 24 hours or so, AMD will publish Radeon Software 16.7.1, which addresses the power distribution issues in the AMD Radeon RX 480. The driver makes two major changes. First, AMD claims that it will lower the draw from the PCIe bus. While they don't explicitly say how, it sounds like it will increase the load on the 6-pin PCIe cable, which is typically over-provisioned. In fact, many power supplies have 6-pin connectors that have the extra two pins of an 8-pin connector hanging off of it.
Second, seemingly for those who aren't comfortable with the extra load on the 6-pin PCIe connector, a UI control has been added to lower overall power. Being that the option's called “compatibility”, it sounds like it should put the RX 480 back into spec on both slot and the extra power connector. Again, AMD says that they believe it's not necessary, and it seems to be true, because that option is off by default.
Beyond these changes, the driver also adds a bunch of game optimizations. Allyn and Ryan have been working on this coverage, so expect more content from them in the very near future.

Unfortunately, I don't have a Sapphire SSC ID, so I cannot verify these myself. That said, a Reddit user by the name of CBwardog found a few extra listings on the company's drop-down menu for products which really shouldn't exist yet. The product name doesn't really have much associated with it, but it does have video RAM and display outputs.

According to Sapphire, the Radeon RX 460 will launch in 2GB and 4GB versions, each of which have one HDMI, one DVI, and one DisplayPort connector. The RX 470 will come in 4GB and 8GB versions. The 4GB version of the RX 470 will have HDMI and three DisplayPorts, while the 8GB version of the RX 470 will have two HDMI ports, one DVI port, and two DisplayPort connectors. Lastly, ignoring the RX 480 that we already know about, a “RADEON 490” (which an earlier leak by AMD called the RX 490) will be available in just an 8GB version, with one HDMI and three DisplayPorts.
As always, rumors should be taken with a grain of salt. Also, it is possible that port configuration could be specific to Sapphire, as we've seen AIB partners modify outputs before, but you would think that there would be at least one reference design per model, so, chances are, it should be fairly uniform across vendors.

Tagged: VR, Oculus, nvidia, graphics drivers, DiRT Rally
A Game Ready Driver has just launched for DiRT Rally VR. GeForce Drivers 368.69 WHQL increments upon the last release, obviously adding optimizations for DiRT Rally VR, but it also includes a few new SLI profiles (Armored Warfare, Dangerous Golf, iRacing: Motorsport Simulator, Lost Ark, and Tiger Knight) and probably other bug fixes.
The update doesn't yet have a release date, but it should be soon. According to NVIDIA's blog post, it sounds like it will come first to the Oculus Store, but arrive on Steam later this month. I haven't been following the game too heavily, but there doesn't seem to be any announcement about official HTC Vive support that I can find.
You can pick them up at NVIDIA's website or through GeForce Experience. Thankfully, the GeForce Experience 3 Beta seems to pick up on new drivers much quicker than the previous version.

NVIDIA is working on a fix to allow the HTC Vive to be connected to the GeForce GTX 1070 and GTX 1080 over DisplayPort. The HTC Vive apparently has the choice between HDMI and Mini DisplayPort, but the headset will not be identified when connected over that connection. Currently, the two workarounds are to connect the HTC Vive over HDMI, or use a DisplayPort to HDMI adapter if your card's HDMI output is already occupied.
It has apparently been an open issue for over a month now. That said, NVIDIA's Manuel Guzman has acknowledged the issue. Other threads claim that there are other displays that have a similar issue, and, within the last 24 hours, some users have experienced luck with modifying their motherboard's settings. I'd expect that it's something the can fix in an upcoming driver, though. For now, I guess plan your monitor outputs accordingly if you were planning on getting the HTC Vive.

Apparently, some people think that AMD will be releasing an RX 490 based on Polaris 10 with an extra four compute units, bringing the total number of stream processors to 2560. I'm guessing that people expected it to be a nice, round number or something, but that's not the case. According to Evan Groenke, Senior Product Manager at AMD, the die has 36 compute units, and there is “nothing else hidden on the product that end users might be looking forward to unlocking”.
Really, this kind-of makes sense. AMD seems to have designed this chip around the performance target of VR, which the RX 480 hits. I don't think that it would really make sense to push about 11% more compute processors into the design, decreasing their yield per wafer for such a relatively small gain.
We are expecting an RX 490 card to land at some point though, thanks to a mistake in publishing on AMD's part. It won't be Polaris 10 or 11.

It appears that MSI will be one of the first AIB partners to get a reference version of the AMD RX 480 graphics card out. Available as soon as next week, the MSI Radeon RX 480 8G pairs AMD’s Polaris-based GPU with 8GB of GDDR5 memory on a reference platform and cooler.
The MSI card uses the AMD reference cooler with a blower style fan and measures 9.45” in length. It is a dual slot design with a red and black aesthetic. Rear IO includes three DisplayPort and one HDMI ports. It is powered by a single 6-pin PCI-E power connector.
There is not much to say with regards to clocks on this GCN4-based card as there are no factory overclocks to speak of. The base clock sits at 1120 MHz (which is an average expected clock, not necessarily the minimum) and the GPU can boost up to a maximum of 1266 MHz out of the box. MSI is clocking the memory at the full 8 GHz though, which is good (AMD stated that partners could clock memory anywhere from seven to eight GHz).
Looking around various retailers, it appears that you will be able to get your hands on it as soon as July 9th from Newegg for $240.
Watch out for pricing before clicking that buy button though, because some sites that allow third party sellers have jacked up the prices quite a bit! If you are looking for a reference design, this card should be as good as the rest. Personally, I am looking forward to MSI and other AIB partner’s custom RX 480 cards which should have much higher overclocking potential and a better power phase setup that should alleviate any power consumption concerns of the reference design’s VRM setup. That is not to say that the reference MSI is going to blow up your PC or anything, but from a buyer's perspective I would rather wait for the custom boards with better coolers that I can push further and faster for only a fairly slight premium. If you need a blower style cooler, this card should work.

Getting a custom-cooled GTX 1080 (for around its MSRP) basically involves monitoring Newegg for a good business week or two, several times per day, pouncing on whatever isn't marked-up. Whether it's low supply or high demand, add-in board vendors haven't stopped announcing new models.

The MSI GTX 1080 8G DUKE is a three-fan (“TriFrozr”) design with an 8-pin and a 6-pin PCIe power connector, which provides 75W more headroom than the Founders Edition. EXPReview claims that it slides between the AERO and the GAMING lines. Although they don't claim how it matches up to ARMOR, which is also between AERO and GAMING, it looks like it's slightly above it, with its RGB LEDs. The GTX 1080 GPU is factory overclocked to 1708 MHz and boosts to 1847 MHz, and the GTX 1070 is overclocked to 1607 MHz with a 1797 MHz boost.
Launch regions are not listed for the cards, but the launch price is supposedly 5399 Chinese Yuan (which converts to $810 USD) and 3499 Chinese Yuan ($524.70 USD) for the GTX 1070. This is quite a bit higher than we would expect, but I'm not sure how regional pricing on electronics works between the USA and China.

Custom graphics cards based on NVIDIA’s GTX 1070 GPU have been rolling out from all the usual suspects, and today small form factor enthusiasts have a new option with Gigabyte’s Mini ITX friendly GTX 1070 Mini ITX OC. As the name implies, this is a factory overclocked card that can hit 1746 MHz boost with the right checkboxes ticked in the company’s vBIOS utility.
The new SFF graphics card measures a mere 6.7-inches long and is a dual slot design with a custom single 90mm fan HSF. It is a custom design that uses a 5+1 power phase design which Gigabyte claims is engineered to provide lower temperatures and more stable voltage compared to Nvidia’s reference design which is a 4+1 setup. The cooler on the dual slot card uses an aluminum fin array that is fed by three direct touch heatpipes. The 90mm fan is able to spin down to 0 rpm when the card is not under load which would make it a good candidate for a gaming capable living room PC that also doubles as your media center. Gigabyte further claims that their "3D stripe" ridged fan blade design helps to reduce noise and improve cooling performance.
Rear IO on the card includes two dual link DVI connectors, one HDMI, and one DisplayPort output. The graphics card is powered by a single 8-pin PCI-E power connector.
As far as the nitty gritty specifications are concerned, Gigabyte has the GTX 1070 GPU clocked out of the box at 1531 MHz base and 1721 MHz boost. Using the company’s Xtreme Engine utility, users can enable the “OC Mode” which automatically clocks the card further to 1556 MHz base and 1746 MHz boost. The OC Mode in particular is a decent factory overclock over the reference clocks of 1506 MHz base and 1683 MHz boost respectively. The 8 GB of GDDR5 memory remains effectively untouched at 8008 MHz.
Unfortunately as is usually the case with these kinds of launches pricing and availability has not yet been announced. From a cursory look around Newegg I would guess that the card will be somewhere around $465 (both the factory overclock and SFF premium).

It is rather difficult to rate the cost to performance ratio of GTX 1080's as the prices and availability are in a constant state of flux but we can certainly peg the overall performance of the cards. [H]ard|OCP recently strapped the new ASUS ROG GTX 1080 STRIX GAMING GPU to their testbed to see how it performs. Right out of the box the cards base clock is 1759MHz with a boost clock of 1898MHz and 10GHz GDDR5X, which [H] successfully raised to 1836MHz base, 1973MHz boost with in game frequencies reaching 2139 MHz and the GDDR5 running at 11.3GHz. This had an effect on performance.
"Today we review in full detail our first custom GeForce GTX 1080 video card. ASUS has decked the ROG GTX 1080 STRIX GAMING out with a factory overclock, the STRIX cooling system, and a fully customizable lighting system. Let's see this beast overclock and compare it to the previous gen's GTX 980 Ti and Radeon R9 Fury X."
