AMD Radeon HD 7970 official review thread

[Terabyte]

I guess Price in India ~ 35K

I feel its more like ~32k

Dear lord. This card is epic win.

Thanks to all the members here for sharing the links. Now going through the reviews. As per my understanding till now, the true or full potential of the 7900 series cannot be achieved with the current reviews because of the lack of tweaks and feature supports in the drivers, deliberately by AMD. There is no software to use its Quicksync like feature for video encoding, no DX 3D 11.1 support. They will make available in the final version of Catalyst 12.2 driver in late February. But the enormous bandwidth and 3GB GDDR5 Ram...already starts bottlenecking the PCI-E 2.0 bus. A perfect solution for 3D, Eye-finity and HD3D Eyefiniy.

Roughly cards are 1.2 times of US price here. So $550 -> $660 at present exchange rate of 53 - 34980 ~ 35k.

Hmmm...then lets hope it comes down by the time it arrives here
Waiting for review by Anandtech!

And here's the CFX performance:-

AMD Radeon HD 7970 CrossFire Performance Review - Introduction


Jaw-dropping numbers at Eyefinity res!

Crossfire scaling is impressive. (it isn't working in some games but will get fixed) GTX 580 3GB SLI gets absolutely annihilated by HD 7970 Crossfire.

AMD Video Codec Engine - AnandTech - AMD Radeon HD 7970 Review: 28nm And Graphics Core Next, Together As One - their reply to Quick Sync.

AMD is saying VCE will allow more options for transcoding compared to Quick Sync, which is good.

So this may be another feature of their next next gen APU.

Just finished the Anandtech Review. Guys, you are concentrating only the gaming performance of these GCN based cards but not on the main purpose of it,computational power and Tessellation performance. And one word to describe it: Its outstanding improvement.

In all the cases it is suprassing GTX 580, sometimes by a light margin, sometimes by a huge margin. It is really good to see that with their 1st iteration of SIMD based design AMD is pulling really heavy weight. Here is the quote from Anandtech for the SmallLuxGPU 2.0d4 benchmark:

Again the 7970 does incredibly well here compared to AMD’s past architectures. AMD already did rather well here even with the limited compute performance of their VLIW4 architecture, and with GCN AMD once again puts their old architectures to shame, and puts NVIDIA to shame too in the process. Among single-GPU cards the GTX 580 is the closest competitor and even then the 7970 leads it by 72%. The story is much the same for the 7970 versus the 6970, where the 7970 leads by 74%. If AMD can continue to deliver on performance gains like these, the GCN is going to be a formidable force in the HPC market when it eventually makes its way there.

So it is clear now that AMD's new GCN architecture excels where it is targeted to do so: The Raw Computational Performace.
Lets wait and see what AMD can do with their next interations.

Oops!! Missed it somehow
I must say the results are more than impressive

 

[Joker]

not as much gain as we expected in gaming..still good enough.

but this is fermi done right....compute and tessellation performance is much higher than nvidia...!!!

hd 7970 runs cool and power efficient.

 

[sukesh1090]

hoohoo.....wow....at last AMD did it and this is just the begining.it stood right to the expectations.

Look at this....HD 7970 completely destroyed 3dMark vantage

ico that was 1.5gb sli and not 3gb.

 

[max_snyper]

read all the reviews...from that i have a doubt....
1.will the next release hd78xx too saturate the pci-e 2.0 or just the hd79xx will do

2.will these card support dx11.1 or after a driver release

3.exactly when will these cards (hd79xx,hd78xx) come to India & price,any speculation?

 

[skeletor]

thx for the correction.

1) Nope. HD 79xx isn't saturating PCIe 2.0 in any means. Except three or four handpicked situations where PCI 3.0 runs slightly faster.

2) Yes.

3) Mid January.

nVIDIA responds, well sort of.

nVidia slashes prices to help welcome Radeon 7970 | KitGuru

 

[max_snyper]

Though we should not directly compare a high end card to a high end card of last generations
Performance is quite impressive...for a single card...!
Pricing will be deciding factor in India expect 30k upwards...

And we should not forget Nvidia's Kepler is about to release in Q2,that would be real competition to AMD's GCN....!

Are hd78xx too GCN or just a die shrink?
