SLI and CrossFire
Last week I sat down with a set of three AMD Radeon R9 Fury X cards, our sampled review card as well as two retail cards purchased from Newegg, to see how the reports of the pump whine noise from the cards was shaping up. I'm not going to dive into that debate again here in this story as I think we have covered it pretty well thus far in that story as well as on our various podcasts, but rest assured we are continuing to look into the revisions of the Fury X to see if AMD and Cooler Master were actually able to fix the issue.
What we have to cover today is something very different, and likely much more interesting for a wider range of users. When you have three AMD Fury X cards in your hands, you of course have to do some multi-GPU testing with them. With our set I was able to run both 2-Way and 3-Way CrossFire with the new AMD flagship card and compare them directly to the comparable NVIDIA offering, the GeForce GTX 980 Ti.
There isn't much else I need to do to build up this story, is there? If you are curious how well the new AMD Fury X scales in CrossFire with two and even three GPUs, this is where you'll find your answers.

As reported by VideoCardz.com the upcoming Radeon Fury card specs have been leaked (and confirmed, according to the report), and the air-cooled card is said to have 8 fewer compute units enabled and a slightly slower core clock.
The report pictures a pair of Sapphire cards, both using the Tri-X triple-fan air cooler. The first is a reference-clocked version which will be 1000 MHz (50 Hz slower than the Fury X), and an overclocked version at 1040 MHz. And what of the rest of the specs? VideoCardz has created this table:
The total number of compute units is 56 (8 fewer than the Fury X), which at 64 stream cores per unit results in 3584 for the non-X GPU. TMU count drops to 224, and HBM1 memory speed is unchanged at 1000 MHz effective. VideoCardz is listing the ROP count at an unchanged 64, but this (along with the rest of the report, of course) has not been officially announced.
The board will apparently be identical to the reference Fury X
Retail price on this card had been announced by AMD as $549, and with the modest reduction in specs (and hopefully some overclocking headroom) this could be an attractive option to compete with the GTX 980, though it will probably need to beat the 980's performance or at least match its $500 price to be relevant in the current market. With these specs it looks like it will only be slightly behind the Fury X so pricing shouldn't be much of an issue for AMD just yet.

Tagged: amd, radeon, fury x, pump whine
According to a couple of users from the Anandtech forums and others, there is another wave of AMD Fury X cards making their way out into the world. Opening up the top of the Fury X card to reveal the Cooler Master built water cooler pump, there are two different configurations in circulation. One has a teal and white Cooler Master sticker, the second one has a shiny CM logo embossed on it.
This is apparently a different pump implementation than we have seen thus far.
You might have read our recent story looking at the review sample as well as two retail purchased Fury X cards where we discovered that the initial pump whine and noise that AMD claimed would be gone, in fact remained to pester gamers. As it turns out, all three of our cards have the teal/white CM logo.
Our three Fury X cards have the same sticker on them.
Based on at least a couple of user reports, this different pump variation does not have the same level of pump whine that we have seen to date. If that's the case, it's great news - AMD has started pushing out Fury X cards to the retail market that don't whine and squeal!
If this sticker/label difference is in fact the indicator for a newer, quieter pump, it does leave us with a few questions. Do current Fury X owners with louder coolers get to exchange them through RMA? Is it possible that these new pump decals are not indicative of a total pump change over and this is just chance? I have asked AMD for details on this new information already, and in fact have been asking for AMD's input on the issue since the day of retail release. So far, no one has wanted to comment on it publicly or offer me any direction as to what is changing and when.
I hope for the gamers' sake that this new pump sticker somehow will be the tell-tale sign that you have a changed cooler implementation. Unfortunately for now, the only way to know if you are buying one of these is to install it in your system and listen or to wait for it to arrive and take the lid off the Fury X. (It's a Hex 1.5 screw by the way.)
Though our budget is more than slightly stretched, I'm keeping an eye out for more Fury X cards to show up for sale to get some more random samples in-house!
Retail cards still suffer from the issue
In our review of AMD's latest flagship graphics card, the Radeon R9 Fury X, I noticed and commented on the unique sound that the card was producing during our testing. A high pitched whine, emanating from the pump of the self-contained water cooler designed by Cooler Master, was obvious from the moment our test system was powered on and remained constant during use. I talked with a couple of other reviewers about the issue before the launch of the card and it seemed that I wasn't alone. Looking around other reviews of the Fury X, most make mention of this squeal specifically.
Noise from graphics cards come in many forms. There is the most obvious and common noise from on-board fans and the air it moves. Less frequently, but distinctly, the sound of inductor coil whine comes up. Fan noise spikes when the GPU gets hot, causing the fans to need to spin faster and move more air across the heatsink, which keeps everything running cool. Coil whine changes pitch based on the frame rate (and the frequency of power delivery on the card) and can be alleviated by using higher quality components on the board itself.
But the sound of our Fury X was unique: it was caused by the pump itself and it was constant. The noise it produced did not change as the load on the GPU varied. It was also 'pitchy' - a whine that seemed to pierce through other sounds in the office. A close analog might be the sound of an older, CRT TV or monitor that is left powered on without input.
In our review process, AMD told us the solution was fixed. In an email sent to the media just prior to the Fury X launch, an AMD rep stated:
In regards to the “pump whine”, AMD received feedback that during open bench testing some cards emit a mild “whining” noise. This is normal for most high speed liquid cooling pumps; Usually the end user cannot hear the noise as the pumps are installed in the chassis, and the radiator fan is louder than the pump. Since the AMD Radeon™ R9 Fury X radiator fan is near silent, this pump noise is more noticeable.
The issue is limited to a very small batch of initial production samples and we have worked with the manufacturer to improve the acoustic profile of the pump. This problem has been resolved and a fix added to production parts and is not an issue.
I would disagree that this is "normal" but even so, taking AMD at its word, I wrote that we heard the noise but also that AMD had claimed to have addressed it. Other reviewers noted the same comment from AMD, saying the result was fixed. But very quickly after launch some users were posting videos on YouTube and on forums with the same (or worse) sounds and noise. We had already started bringing in a pair of additional Fury X retail cards from Newegg in order to do some performance testing, so it seemed like a logical next step for us to test these retail cards in terms of pump noise as well.
First, let's get the bad news out of the way: both of the retail AMD Radeon R9 Fury X cards that arrived in our offices exhibit 'worse' noise, in the form of both whining and buzzing, compared to our review sample. In this write up, I'll attempt to showcase the noise profile of the three Fury X cards in our possession, as well as how they compare to the Radeon R9 295X2 (another water cooled card) and the GeForce GTX 980 Ti reference design - added for comparison.

[H]ard|OCP used a slightly different configuration to test the new R9 Fury X, an i7-3770K on an ASUS PB287Q as opposed to an i7-3960X and an ASUS P9X79, the SSD is slightly different but the RAM remains the same at 16GB of DDR3-1600. [H] also used the same driver as we did and found similar difficulties using it with R9-2xx cards which is why that card was tested with the Catalyst 15.5 Beta. When testing The Witcher 3 the GTX 980 Ti came out on top overall but it is worth noting the Fury's 70% performance increase over the 290X when HairWorks was enabled. Their overall conclusions matched what Ryan saw, read them for yourself right here.
"We review AMD's new Fiji GPU comprising the new AMD Radeon R9 Fury X video card with stacked chip technology High Bandwidth Memory. We take this video card through its paces, make comparisons and find out what it can do for us in real world gameplay. Is this $649 video card competitive? Is it truly geared for 4K gaming as AMD says?"

A fury unlike any other...
Officially unveiled by AMD during E3 last week, we are finally ready to show you our review of the brand new Radeon R9 Fury X graphics card. Very few times has a product launch meant more to a company, and to its industry, than the Fury X does this summer. AMD has been lagging behind in the highest-tiers of the graphics card market for a full generation. They were depending on the 2-year-old Hawaii GPU to hold its own against a continuous barrage of products from NVIDIA. The R9 290X, despite using more power, was able to keep up through the GTX 700-series days, but the release of NVIDIA's Maxwell architecture forced AMD to move the R9 200-series parts into the sub-$350 field. This is well below the selling prices of NVIDIA's top cards.
The AMD Fury X hopes to change that with a price tag of $650 and a host of new features and performance capabilities. It aims to once again put AMD's Radeon line in the same discussion with enthusiasts as the GeForce series.
The Fury X is built on the new AMD Fiji GPU, an evolutionary part based on AMD's GCN (Graphics Core Next) architecture. This design adds a lot of compute horsepower (4,096 stream processors) and it also is the first consumer product to integrate HBM (High Bandwidth Memory) support with a 4096-bit memory bus!
Of course the question is: what does this mean for you, the gamer? Is it time to start making a place in your PC for the Fury X? Let's find out.

Tagged: radeon, r9 390, hawaii, catalyst, amd, 15.15
During the course of our review of the new Sapphire Nitro R9 390 8GB card earlier this week, a question came up on driver support. For testing the R9 300-series as well as the Fury X cards, AMD provided a new Catalyst 15.15 beta driver. The problem is that these drivers would not install on the Radeon R9 200-series cards. That's not totally uncommon on new GPU releases but it does seem a bit odd considering the similarities between the R9 390 and the R9 290, for example.
That meant that in our review we had to use the Catalyst 15.5 beta for the Radeon R9 290X and the Radeon R9 290 GPU while using the newer Catalyst 15.15 beta for the Sapphire Nitro R9 390. Eyebrows were raised as you would expect as any performance differences between the new cards and the old cards would have to take into account the driver changes as well. But since we couldn't install the new driver on the old hardware, we were stuck, and published what we had.
Since then, a driver with some INI modifications that allows Catalyst 15.15 to be installed on Radeon R9 290X/290 hardware was built and uploaded from the Guru3D Forums. Today I installed that on our XFX Radeon R9 290 4GB card used in our R9 390 review to re-run a few game tests to see what changes we saw, if any. This would help us address any concerns over the updated driver causing performance changes rather than the hardware changes.
(Note: I realize that using an INI hacked driver isn't exactly going to pass QA with AMD, but I think we are seeing results that are close enough.)
First up, let's look at Grand Theft Auto V.
In GTA V we see that the average frame rate at 2560x1440 goes from 39.5 FPS to 40.5 FPS, an increase of about 2-3%. That's minimal but it is interesting to see how the frame rate consistency changes as we move down the sliding scale; pay attention to the orange and pink lines in the FPS by Percentile graph to see what I am referencing. As you move into the slower frame times in our testing, the gap between the 15.5 and 15.15 driver begins to widen slightly, indicating a little more frame time consistency in 15.15 release.
But what about BF4 or Metro: Last Light?
The new Radeon R9 300-series
The new AMD Radeon R9 and R7 300-series of graphics cards are coming into the world with a rocky start. We have seen rumors and speculation about what GPUs are going to be included, what changes would be made and what prices these would be shipping at for what seems like months, and in truth it has been months. AMD's Radeon R9 290 and R9 290X based on the new Hawaii GPU launched nearly 2 years ago, while the rest of the 200-series lineup was mostly a transition of existing products in the HD 7000-family. The lone exception was the Radeon R9 285, a card based on a mysterious new GPU called Tonga that showed up late to the game to fill a gap in the performance and pricing window for AMD.
AMD's R9 300-series, and the R7 300-series in particular, follows a very similar path. The R9 390 and R9 390X are still based on the Hawaii architecture. Tahiti is finally retired and put to pasture, though Tonga lives on as the Radeon R9 380. Below that you have the Radeon R7 370 and 360, the former based on the aging GCN 1.0 Curacao GPU and the latter based on Bonaire. On the surface its easy to refer to these cards with the dreaded "R-word"...rebrands. And though that seems to be the case there are some interesting performance changes, at least at the high end of this stack, that warrant discussion.
And of course, AMD partners like Sapphire are using this opportunity of familiarity with the GPU and its properties to release newer product stacks. In this case Sapphire is launching the new Nitro brand for a series of cards that it is aimed at what it considers the most common type of gamer: one that is cost conscious and craves performance over everything else.
The result is a stack of GPUs with prices ranging from about $110 up to ~$400 that target the "gamer" group of GPU buyers without the added price tag that some other lines include. Obviously it seems a little crazy to be talking about a line of graphics cards that is built for gamers (aren't they all??) but the emphasis is to build a fast card that is cool and quiet without the additional cost of overly glamorous coolers, LEDs or dip switches.
Today I am taking a look at the new Sapphire Nitro R9 390 8GB card, but before we dive head first into that card and its performance, let's first go over the changes to the R9-level of AMD's product stack.

It's finally official: AMD Radeon R9 Fury X and Fury graphics cards are coming soon. Here's the details you need to know:
|AMD Fury X||AMD Fury||AMD R9 290X|
|Compute Capability||8.6 TFLOPS||??||5.6 TFLOPS|
|Transistor Count||8.9 billion||??||6.3 billion|
|Availability||June 24th||July 14th||Now|
There is still a lot of information that AMD is saving for the official release, but those look to be some impressive graphics cards at first glance! The AMD Fury X is the small form factor water cooled version that we saw leaked this weekend while the AMD Fury (non-X) will be air cooled. It wasn't shown on stage though, so we can only guess what it will look like.
AMD's Joe Macri said on stage that the cooler they designed is built for up to 500 watts but that the board was only going to draw 275 watts, while keeping the board temperature down to 50C!
Other tidbits include 6-phase power with 400A (!!) power delivery for overclocking, an 8-LED user addressable array for performance load monitoring and 1.5x performance per watt improvement when compared to the R9 290X. That can help us estimate card performance but we'll dive more into that later.
Finally, though only a tease, AMD did say they were planning a dual-GPU variant of Fiji coming "in the fall."
