AMD unleashes Radeon HD 7970

Written by



Fastest single GPU card on the planet


AMD’s first Southern Islands card is finally here. The Radeon HD 7970 was officially announced today and the new 28nm GPU is said to deliver world beating performance.

There’s not much point in talking about the specs, since we’ve been talking about Southern Islands cards for months, but here’s a brief recap of AMD’s flagship just in case you missed anything. The card features 2,048 shaders, 3GB of GDDR5 memory on a 384-bit bus, 6- and 8-pin power connectors and a bunch of video outputs, including two micro DisplayPort connectors, DVI, HDMI and Eyefinity support. The memory is clocked at 1375MGz, so bandwidth stands at an impressive 264GB/s. The new Tahiti GPU consists of 4.3 billion tiny 28nm transistors and it runs at 925MHz.

So how does it stack up against the previous generation, and perhaps more importantly, against Nvidia’s high end cards? Well, according to early reviews it easily beats previous single-GPU cards from both camps, but it still lags behind the dual-headed HD 6990 and GTX 590 in most tests.

Of course, one of the more interesting aspects of the new architecture is power efficiency, as it will give us a rough idea of what to expect from future 28nm cards. Anand ran a few comprehensive tests and the figures seem pretty good. Idle power consumption has been vastly improved and it is second to none, the same goes for idle temperature. Under load the HD 7970 also performs admirably so it is safe to assume that 28nm cards will have a lot of overclocking potential.

We will have more on the HD 7970 launch/review bonanza later in the day, so stay tuned. So far so good, kudos AMD.

The GPU department of AMD is very good, the cpu could be better though. I wonder why ATI just sold itself to AMD. I like AMD but I also liked ATI

The graphics performance is good, but i wanted to see more. AMD's real focus this time around seems to have been compute rather than graphics. AnandTech's review details that aspect. As Ryan says "GCN would be AMD’s Fermi".

Seems the GCN architecture will also be incorporated into future APUs (~2013). I think AMD is trying to leverage the fact that GPUs can do tasks faster than CPUs. So GCN will not only be an architecture for GPUs but also for their APUs. Just my guess.

With the rest of the £1000+ cards (in a rich man's house) :P

Don't worry soon AMD will be in massive debt & sell itself like a street-walker to Samsung. Samsung will demolish the company bit by bit & Intel will buy ATI part from them for only $1 billion...Samsung will use a handful of amd engineers to develop arm processors for windows 8, Samsung will launch their own line of computers like apple. In the end the entire AMD name will be finished & it will cease to exsit. R.I.P AMD - 1969 - 2012 8)

Reason why they go in debt & why they are liars is here - http://scalibq.wordpress.com/2011/08/11/yes-amd-fanboys-are-idiots/

I would say fastest single core GPU in our SOLAR SYSTEM ;)

Keep on dreaming...

ATI was bought by AMD when ATI almost dissolve to oblivion.

I expected more for the cost of this GPU. Anyhow it does perform quite well against the HD 6970 but not consistent. Hopefully with driver updates along with bios updates the HD 7970 will perform as good as based on it's high price.

Right now the HD 7970 should cost around $449, NOT $549.... IMO...

Talk to me in July 2012 when Samsung buys AMD until then u give urself false sense of well-being with AMD... AMD will be exposed! 8)

You are joking right? ATI was very strong financially when they were “ATI”. AMD on the other hand at the time was also strong financially but needed ATI to fulfill its FUSION ARCITECTURE, so they offered to buy them out.
In my Opinion, AMD’s biggest mistake was removing the ATI logo because ATI + Radeon are very popular within the world. AMD could have leveraged the two for stronger sales. The POLLS which AMD conducted was one sided, it was meant to ensure the ATI logo be dissolved and scraped.
What AMD should have done IMO is ATI Technologies, a Division of Advanced Micro Device (AMD).
