Introduction and Package

Sapphire's TOXIC name isn't one we've heard for a while. Originally we heard about the branding a little bit behind the scenes in January, but nothing eventuated. For the most part we think it was a combination of Sapphire trying to get the clocks they wanted combined with the fact that stock wasn't the best earlier in the year.
Jump forward over six months, though, and we've got the new GHz Edition HD 7970 from AMD which means we've got some higher binned GPUs. That should ultimately mean we've got a chance to get even better clock speeds than ever. The TOXIC series is one that has always impressed us and we hope this trend continues with the latest model.
As always, though, there are a few things we need to do before we find out just what the new TOXIC based HD 7970 GHz Edition video card is capable of. The first thing we're going to do is check out the package and bundle. Because Sapphire got the card to us nice and early, we didn't have the full retail package and bundle included.
Sapphire was able to send us over an image of the box, though, so we can work off that and we have got the cable bundle included so we can cover that as well. Next we'll move onto the card itself to see what's going on with the cooler that Sapphire has opted for before we check out the specifications and see just what the TOXIC branding brings in terms of clock speeds.
We'll quickly cover the testbed and the cards that will be included in our graphs today before we finally get into the fun stuff and see just what kind of performance we're able to get out of this bad boy before we wrap everything up in our final thoughts. First, though, let's get into the package to see just what's going on.
Package

Having a look at our box render we can see that the video card is clearly part of the TOXIC series and based on the new GHz Edition of the Radeon HD 7970 GPU which just launched last month. The other big stand out on the box, though, is the massive 6GB of GDDR5 that is present. This is something we haven't seen from anyone yet and it's great to see Sapphire make the move.

While we're missing the likes of a driver CD, manual and CrossFire bridge, you can see starting from the left we've got a Mini DisplayPort to DisplayPort connector, Mini DisplayPort to DVI, full length HDMI cable, two dual Molex to 8-pin PCIe power connectors along with a DVI to VGA connector to round off the bundle side of things. Sapphire has been strong when it's come to connectors on the HD 7000 series and this time is no different.
The Card and Specifications
The Card

It comes as no surprise that Sapphire has opted for a dual fan solution on the HD 7970 GHz Edition TOXIC. The next piece that really stands out to us is the all black PCB that you can see bits off. Along with that you can see copper heatpipes coming out the bottom and of course we've got a massive aluminum heatsink on offer that takes up majority of the card. You can see we've also got a pretty sweet fan shroud going on that has some see through bits making for a really good looking card.

While we'd normally take a quick spin around the card at this point, we have turned it over this time around, as we've got a massive plate that covers the back of the card. We can also see some heatsinks on the back of the card along with some Vapor-X branding which is what the cooler is. Front and back, the new Sapphire HD 7970 GHz Edition TOXIC is really good looking.

Looking towards the back you can see the power connector setup which in this case is a dual 8-pin PCIe setup. The original HD 7970 and GHz Edition that was released last month carried an 8-pin + 6-pin PCIe setup, but we see higher end models opt for a dual 8-pin setup.

Closer to the front you can see we've got two CrossFire connectors present that would give us the ability to run up to four of these cards. That would be near impossible, though, as the cooler does just tip over the normal dual slot width. Sapphire has opted to drop the BIOS switch, though, for a button which looks a lot nicer. It also comes in really helpful. We'll cover that more in just a moment when we move over to the specification side of things.

Finally we finish up with the I/O side of things and you can see we've got two DVI connectors in the form of a Dual-Link one and Single-Link one Along with that we've got a single HDMI port and two Mini DisplayPort connectors. You can see Sapphire has also opted for a slightly custom back plate which opens the card up a little more to give the fan a little bit more breathing room. Normally we'd just have the vent across the top, but in this case, you can clearly see that it's been opened up a bit more around the Mini DisplayPort and HDMI area.
Specifications
Out of the box we know the new GHz Edition HD 7970 from AMD carries a core clock of 1050MHz while the 3GB of GDDR5 comes in at an even 6000MHz QDR. The TOXIC version from Sapphire comes in at 1100MHz while the increased 6GB of GDDR5 comes in at the same 6000MHz QDR.

Pressing the button that sits next to our CrossFire connectors, though, pushes the core to 1200MHz while the 6GB of GDDR5 is pushed even higher coming in at 6400MHz QDR. These are some attractive clocks and should bring with it some excellent performance.
Again, though, I find myself a little puzzled as to why Sapphire really worry about the lower clocks / button option when they could just have the card running at 1200MHz / 6400MHz QDR out of the box. If you're buying this card, I'm not sure why you'd bother with the 1100MHz / 6000MHz QDR option when an even stronger overclock is a push away.
Benchmarks - Test System Setup

We would like to thank the following companies for supplying and supporting us with our test system hardware and equipment: Intel, ASUS and Corsair.
One of the main cards we want to compare the HD 7970 GHz Edition TOXIC against today is of course the reference clocked HD 7970 GHz Edition. We also want to see how the numbers look against the original HD 7970 that was launched back in December of last year.
More importantly, though, for probably both AMD and Sapphire is how this TOXIC version compares against the current crop of high-end NVIDIA GEFORCE video cards. That's why we've got both the reference GTX 670 and GTX 680 on offer along with the 4GB GTX 680 from Palit and the pre-overclocked Phantom model from Gainward.
Let's get started!
The FPS Numbers Explained
When we benchmark our video cards and look at the graphs, we aim to get to a certain level of FPS which we consider playable. While many may argue that the human eye can't see over 24 FPS or 30 FPS, any true gamer will tell you that as we climb higher in Frames Per Seconds (FPS), the overall gameplay feels smoother. There are three numbers we're looking out for when it comes to our benchmarks.
30 FPS - It's the minimum number we aim for when it comes to games. If you're not dropping below 30 FPS during games, you're going to have a nice and smooth gaming experience. The ideal situation is that even in a heavy fire fight, the minimum stays above 30 FPS making sure that you can continue to aim easily or turn the corner with no dramas.
60 FPS - It's the average we look for when we don't have a minimum coming at us. If we're getting an average of 60 FPS, we should have a minimum of 30 FPS or better and as mentioned above, it means we've got some smooth game play happening.
120 FPS - The new number that we've been hunting down over recent months. If you're the owner of a 120 Hz monitor, to get the most out of it you want to get around the 120 FPS mark. Moving from 60 FPS / 60 Hz to 120 FPS / 120 Hz brings with it a certain fluidity that can't really be explained, but instead has to be experienced. Of course, if you're buying a 120 Hz monitor to take advantage of 3D, an average of 120 FPS in our benchmark means that in 3D you will have an average of 60 FPS, which again means you should expect some smooth gameplay.
Benchmarks - 3DMark 11

Tom Clancy's H.A.W.X. 2 is an arcade-style flight action game developed by Ubisoft Romania and published by Ubisoft. The game is the sequel to Tom Clancy's H.A.W.X., released in 2009.
The game begins with Colonel David Crenshaw participating in a routine patrol mission in the Middle East. After halting an insurgent attack, a volley of missiles is fired at the Air Force base that Crenshaw was stationed at, with one of the missiles disabling Crenshaw's aircraft, resulting Crenshaw being in enemy captivity. A joint strike force composed of the U.S. Navy, U.S. Air Force, and a Ghost Recon squad executes an operation to rescue Crenshaw. In Scotland, Royal Navy Pilot Colin Munro encounters an unidentified passenger aircraft that explodes from an on-board bomb when undergoing training exercise. In Russia, an air force squadron led by Colonel Denisov and Captain Dmitri Sokov engages separatist aircraft but is ordered to retreat from the region after numerous Russian military installations have been attacked.

H.A.W.X. 2 has always favored the NVIDIA offerings and while we do see a nice boost in performance here you can see that we still fall behind the NVIDIA based models. Compared to the other HD 7970s, though, we do see a nice boost in overall performance and our numbers are extremely impressive at all resolutions.
Benchmarks - Mafia II
Mafia II
Version and / or Patch Used: Latest Steam Update
Timedemo or Level Used: Built in Benchmark
Developer Homepage: http://www.2kczech.com/
Product Homepage: http://www.mafia2game.com/

Mafia II is a third-person action-adventure video game, the sequel to Mafia: The City of Lost Heaven. It is developed by 2K Czech, previously known as Illusion Softworks, and is published by 2K Games. The game is set from 1943 to 1951 in Empire Bay (the name is a reference to New York's state nickname "The Empire State"), a fictional city based on San Francisco and New York City, with influences from Chicago and Detroit. The game features a completely open-ended game map of 10 square miles. No restrictions are included from the start of the game. There are around 50 vehicles in the game, as well as licensed music from the era.

Getting into Mafia II we start to see what AMD is really good at. Looking at 1680 x 1050 and 1920 x 1200 performance we can see that the Sapphire HD 7970 GHz Edition TOXIC sits around the same level as the GTX 680 4GB and pre-overclocked Phantom model.
Where we see the card really shine, though, is when we move to 2560 x 1600 in where we see the Sapphire offering come out ahead of everything else.

Product Homepage: http://www.lostplanet2game.com/

Lost Planet 2 is a third-person shooter video game developed and published by Capcom. The game is the sequel to Lost Planet: Extreme Condition which is also made by Capcom, taking place ten years after the events of the first game, on the same fictional planet. The story takes place back on E.D.N. III 10 years after the events of the first game. The snow has melted to reveal jungles and more tropical areas that have taken the place of more frozen regions. The plot begins with Mercenaries fighting against Jungle Pirates. After destroying a mine, the Mercenaries continue on to evacuate the area, in which a Category-G Akrid appears and attacks them. After being rescued, they find out their evacuation point (Where the Category-G appeared) was a set-up and no pick up team awaited them. The last words imply possible DLC additions to the game, "There's nothing to be gained by wiping out snow pirates... unless you had some kind of grudge."

Under Lost Planet 2 we can see that 1920 x 1200 and 1680 x 1050 performance is below even the reference clocked GTX 680. As soon as we move to 2560 x 1600, though, and really apply the pressure, we see that the Sapphire offering again manages to outperform all of the others.

Aliens vs. Predator is a science fiction first-person shooter video game, developed by Rebellion Developments, the team behind the 1999 original PC game, and published by Sega for Microsoft Windows, the PlayStation 3 and the Xbox 360. The game is based on the Alien vs. Predator franchise, a combination of the characters and creatures of the Alien franchise and the Predator franchise. There are three campaigns in the game, one for each race/faction (the Predators, the Aliens and the Colonial Marines), that, while separate in terms of individual plot and gameplay, form one overarching storyline.
Following the storyline of the campaign modes comes the multiplayer aspect of the game. In this Multiplayer section of the game, players face off in various different gametypes in various different ways.

The new HD 7000 series have been performing very well under Aliens vs. Predator and the Sapphire HD 7970 GHz Edition TOXIC helps extend that lead. The most appreciated gains are at 2560 x 1600 where we see more breathing room as we break into the 70 FPS area.

Metro 2033 is an action-oriented video game with a combination of survival horror and first-person shooter elements. The game is based on the novel Metro 2033 by Russian author Dmitry Glukhovsky. It was developed by 4A Games in Ukraine and released in March 2010 for Microsoft Windows and Xbox 360.[3] In March 2006, 4A Games announced a partnership with Glukhovsky to collaborate on the game.[4] The game was announced at the 2009 Games Convention in Leipzig;[5] a first trailer came along with the announcement.[6] A sequel was announced, currently titled Metro: Last Light.

Looking above at Metro 2033 performance we've got good looking numbers across the board. At 2560 x 1600 we can see the Phantom GTX 680 pulls in a solid 60 FPS. The GHz Edition of the HD 7970 pulled in an improved 62 FPS and you can see the Sapphire TOXIC version manages to pull in a very solid 67 FPS.

It delivers the most realistic destructible environments, amazing special effects such as dynamic fire propagation and storm effects, real-time night-and-day cycle, dynamic music system, non-scripted enemy A.I. and so much more.

Far Cry 2 performance is extremely strong as you'd expect and at the highest resolution we can see that the Sapphire offering again manages to come out of everything else with some fantastic numbers.
Benchmarks - High Quality AA and AF
High Quality AA and AF

While we test all our games with maximum in-game settings, turning on Anti-Aliasing (AA) and Antistrophic Filtering (AF) helps take the intensity of our testing to another level.
Here we see video cards go from playable FPS to an unplayable FPS and the real power houses continue to help break that 60 FPS mark we always aim for to provide a smooth gaming experience.

Mafia II performance is really strong and you can see the Sapphire HD 7970 GHz Edition TOXIC manages to be the only video card that breaks the 60 FPS barrier at 2560 x 1600.

Unfortunately we don't have the same success at 2560 x 1600 under Aliens vs. Predator. The TOXIC does manage to come out ahead of everything else, though, and the only other card to break the 70 FPS mark is the GHz Edition reference clocked card.

Far Cry 2 performance is very strong as you'd expect and you can see we've got very playable FPS at both resolutions, which is exactly what we love to see.

We can see all our cards perform strong under Metro 2033 when it comes to 1920 x 1200. Moving to 2560 x 1600, though, we see everything struggle and while we do see a nice boost on our Sapphire HD 7970 GHz Edition TOXIC card, it's not quite enough to provide what we consider a solid gaming experience.

Just Cause 2 numbers look awesome and you can see the Sapphire HD 7970 GHz Edition TOXIC card is the only one that's able to break the 60 FPS mark. Even if it's just by a single FPS, it's ultimately all we need.
Temperature Test
The temperature of the core is pulled from MSI Afterburner with the max reading used after a completed run off 3DMark Vantage and the Performance preset.

Looking at the temperature numbers of the Sapphire HD 7970 GHz Edition TOXIC we can see that the Vapor-X cooler clearly does a very good job with a very healthy looking load number considering the amount of performance that this video card puts out.
Sound Test
Pulling out the TES 1350A Sound Level Meter we find ourselves quickly yelling into the top of it to see how loud we can be.
After five minutes of that we get a bit more serious and place the device two CM away from the fan on the card to find the maximum noise level of the card when idle (2D mode) and in load (3D mode).

Noise levels are a little on the higher side, but considering the amount of performance that is coming out of the card and the temperature we're getting, this number isn't too bad at all and the larger fans mean that the noise levels aren't as aggressive verse a card that has smaller fans.
Power Consumption Test
Using our PROVA Power Analyzer WM-01 or "Power Thingy" as it has become quickly known as to our readers, we are now able to find out what kind of power is being used by our test system and the associated graphics cards installed. Keep in mind; it tests the complete system (minus LCD monitor, which is plugged directly into AC wall socket).
There are a few important notes to remember though; while our maximum power is taken in 3DMark06 at the same exact point, we have seen in particular tests the power being drawn as much as 10% more. We test at the exact same stage every time; therefore tests should be very consistent and accurate.
The other thing to remember is that our test system is bare minimum - only a SSD hard drive is used with a single CD ROM and minimal cooling fans.
So while the system might draw 400 watts in our test system, placing it into your own PC with a number of other items, the draw is going to be higher.

Power draw numbers like most HD 7000 series based cards look good and if you're buying a card like this then you should have a good quality power supply all ready that won't have an issue dealing with this model from Sapphire.
Final Thoughts
Sapphire has put together a really nice video card here and this is the first retail model we've seen that falls in under the new GHz Edition labeling that we saw AMD launch last month. Looking at what Sapphire is offering us out of the box we get a good idea of just what the new crop of GPUs are capable of achieving.
The thing is, though, looking at the TOXIC model, you can't just thank Sapphire for doing such a good job. Without the foundation that AMD has put forth on the new GHz Edition cards which carrier a higher binned GPU, Sapphire wouldn't have been able to offer a product with such strong performance out of the box and performance is what this video card does extremely well.
We can continue to see that the area AMD shine in is at 2560 x 1600. It's here that we see the Sapphire card be the only one that breaks the 60 FPS barrier at times or just offer us generally better performance than its NVIDIA counterparts. While the TOXIC name took a while to show up again, Sapphire has been able to do it very quickly with these new GHz Edition based GPUs.
Moving away from the raw FPS side of things and looking at the card itself we can see the cooler does an excellent job of keeping our GPU cool. The biggest problem is that it's ultimately come at the cost of extra noise as the trade off. While on the loud side of things, though, the noise isn't aggressive and considering the temperature of the core and the performance of the card, we're not too worried about the number. Outside of the clocks and the cooler, the other big feature is of course the huge amount of memory. It's great to see that Sapphire has opted for 6GB of GDDR5 and I think we'll see some other companies follow in the coming weeks.
As far as the bundle goes we've got a strong one which offers us those extra cables that we're used to seeing from Sapphire helping them stand out a bit more than the competition. Really the only piece of the puzzle that needs to be filled now is the price of the Sapphire HD 7970 GHz Edition TOXIC 6GB. Pricing continues to be a bit of an unknown area, though, not just for this model, but for the new GHz Edition cards in general. Of course this variant is going to cost even more as we not only move over to a really strong overclock, but see the memory doubled to 6GB of GDDR5.
I think over the next few months we'll start to see companies release stronger versions of the GHz Edition card as they get a chance to play with the new GPUs a bit more. For now, though, this Sapphire version is very much a standout model from every aspect with overall performance being the highlight.
If you're in the market to jump on the new GHz Edition and you're after something that can perform stronger than a GTX 680 that is pre-overclocked, this is going to be a simply awesome purchase. Sapphire using the new GHz Edition HD 7970 as a base has done an awesome job with the TOXIC here and doubling the memory out to 6GB is really the cherry on top.
