Mit der Radeon HD 7950 stellt AMD die zweite Grafikkarte mit der neuen GCN-Architektur vor. Wir haben uns das Referenzdesign und eine Version von PowerColor (PCS+) ausführlich angeschaut. Neben den Single-GPU-Tests untersuchen wir darüber hinaus die CrossFire-Performance und werden heraus finden, wie sich die Radeon HD 7950 mit den Taktraten des größeren Bruders, der Radeon HD 7970, schlägt.
The AMD Radeon HD 7950 3GB video card is the toned down version of the Radeon HD 7970 GB and it costs $100 less. AMD sent over a pair of cards for us to try out in CrossFire mode. Read on to see how AMD Radeon HD 7950 does in a multi-GPU CrossFire setup when it comes to performance, power consumption, overclocking and more!
Last week we published an article about a new way of testing graphics card performance in video games. Traditionally, graphics cards performance has been expressed in frames per second. The assumption has always been, the more fps your graphics card is capable of, the better video games will perform. But is it really that simple? Not quite so, it turns out. To really determine how a graphics card handles a video game, the average fps is not an adequate measure of performance, and you need to delve deeper. Frametime tests do exactly that.
Regardless of the reason for its "late" arrival the 7950 launches today and one of our launch day cards is Sapphires 7950 Overclock. With a custom PCB and cooler this factory overclocked card has two different BIOS profiles and is without doubt one of the more interesting models available. We will be putting it up against overclocked versions of the GTX 580 3GB, 7970 and 6970 to find out how each performs on Intel i7/X79 @ 5.0GHz.
AMD hat für die Radeon HD 7950 ein BIOS-Update bereitgestellt, das die GPU-Taktrate der Radeon HD 7950 erhöht und darüber hinaus „PowerTune mit Boost“ hinzufügt.
The new Radeon HD 7950, which is being released today, is a more affordable version of the Radeon HD 7970. Let's check its performance and see if it is a good choice for users looking for a high-end video card.
At the end of the day, the NVIDIA GeForce GTX 760 2GB and the AMD Radeon HD 7950 3GB video cards perform very closely together. For right around $250 either of these cards are more than capable of powering a single monitor gaming system without a problem. We were also impressed by what they could do on a 5760x1080 triple monitor setup thanks to NVIDIA Surround and AMD Eyefinity...
Graphic cards
We all knew that AMD were going to launch the 7000 series graphics cards, but not many anticipated that it would be quite this soon, with AMD bringing the date forward from the 9th January 2012 to 22nd December 2011.
By AMD bringing the date forward, the major downside to this is that it doesn't give us much time as writers to get you the very best content possible, as we have to aim to test the card to its full capacity in a limited time frame, so that we're ready for launch.
That aside, we are pleased to tell you that the 7000 series is here, or at least the 7970 is, with a reference design, while 7950 and 7970 partner cards will still be launched on 9th January 2012, so be sure to look out for that one. Not a lot of information was leaked about the 7970, but if previous card launches were anything to go by, we had a feeling that this could go horribly wrong and we say that for two main reasons. Generally when AMD launch a graphics card, they forget a vital thing, and that is to actually have the cards to launch. That involves making sure the reviewers have the cards, and so that stock is plentiful in stores and sadly this has happened again, but without digressing too much, we find one major flaw that tends to hiccup every time; rebadging.
When we've seen cards launch before, we've typically seen a bit of a rehash of an older card, much like we saw with the 5770/6770 and 5850/6850 and generally when they have launched, the performance has been slightly worse, so you can understand our downward view when we heard about the 7970.
From looking at the architecture however, it does seem that this card is a little bit different with a completely new GPU core and new technologies to back it up, and I can honestly say, from a first glance, it does seem as though AMD are learning from their mistakes.
The new GPU, codenamed "Tahiti" is part of the "Southern Islands" range of graphics cores and is now currently dubbed as their flagship graphics card with the 7970. Other cards are due to be released in the near future and with January 9th becoming ever so close to the present, we should see the 7970 being customised with different coolers and unique overclocks, but for now, let's take a look at the reference Radeon 7970 from AMD.
It unusual for us to miss an NDA, especially when we've got the sample on hand. The simple fact is that AMD chose to Grinch out on us and ignore the holiday spirit, a time when we tend to be able to relax for a few weeks before the CES run of products start to show up. With not only a 10 day holiday planned, but a decision to move from Perth, Australia to Taiwan just three months ago all in the works, the HD 7970 NDA was just one that wasn't going to be met, even though, our sample was sitting safely in Taiwan waiting for my arrival.
With a couple of samples built up over the last few weeks, the HD 7970 was straight on top and today we'll be finally checking out what the new model is all about. Unfortunately it wasn't just a matter of testing the HD 7970 and we could get on our way, along with that we tested a couple of other cards with the most recent drivers to see just what's going on with this new single GPU card from AMD.
AMD has officially launched the Radeon HD 7000 series of graphics cards with the introduction of the companies new flagship single GPU graphics card, the AMD Radeon HD 7970. We put the AMD Radeon HD 7970 to the test on with an Intel Core i7-3960X on the Intel X79 platform with PCI Express 3.0 enabled to see how this card performs. We also overclock it as far as we could to see what the Radeon HD 7970 can do!
