AMD: Southern Islands (7*** series) Speculation/ Rumour Thread

With all the 2048 shaders enabled the comparison is not fair.
If they want an apples-to-apples comparison they should test the same amount of everything, eg number of shaders, frequency, memory bandwidth, etc...
Do to the varying clock frequencies with the 680 we should see results of the 7970 clocked at/near the 680 boost rate. My only concern was the actual clock rates for each benchmark. The 7970 should have been clocked at both 1058MHz and 1100MHz to cover the varying frequencies between games/runs.

Oh, yes , thanks for this.
Quite a "good" argument- if we don't know the exact frequency, then let's overclock the other card, perhaps we might do AMD a favour...

But it's fair that the GTX 680 keeps its higher tessellation rate?

Seriously, this will be impossible to do anyway... or this will mean 1 AMD shader ( ALU ) is the same of an Nvidia shader ( Cuda Alu ), and both architecture are exactly the same ... At this point we can OC the 680 for match the Tflops of the 7970 too . ( lol for DP, the 680 will need to do 5ghz without turbo . )
Both cards are oc easy, and you can find retail cards using similar clock on each brand ... so it is interessant to see if you buy y Gigabyte 7970 who run at 1050mhz in a shop what it is worse against the 680 who have a turbo clock speed gling from 1058mhz to 1110mhz ( in the best case, as some do 1058, 1084 or 1110 in retail ) ... It is too interessant to see if both architecture are clocked at the exact same clock speed, what happend . or if a 7970 retail OC from a brand x or y is worse against a 680 from a brand x or y . They are so close ... so it is even more important... nobody say you need to clock the 7970 at 1300mhz for reach the performance of a 680 at stock speed .. we speak about card you can find in shop .. or if you have a reference 7970, just put 75mhz more and be happy.
What is really strange is, we dont see so much review comparing 680 retail OC vs 7970 retail OC or 680 stock review who have add 7970 retail cards OC ... Price wise this could be a good comparaison too.
For the good or the bad, i remember thoses last 2 years this was more the case.. specially if price was close . Now i see 670SC vs 670 stock ( interessant ofc ), 680 OC vs 680 stock vs 7970 stock ( who is in the chart ), but 7970Msi Lighthning vs 680 Gigabyte OC vs stock ... not so much ... I have not even seen a Asus DCII Top 7970, vs Asus DCII 680 vs Asus stock 680 and stock 7970 .. If you want to do the comparaison, you will need read 3 review minimum on the same site, and like thoses last years, read one review is allready not enough for draw any conclusion, you can multiply this by 2 -3 sites (as no one have the same results and you need do an average for draw a conclusion ... ( erf my headache start again )

Not better sillicon... the 7970M use a 7870 core with lower clock speed .... but without confirmation, you need know you can change the tesselation level on CCC, this change dramatically the score in 3D mark 11.
I dont know where thoses scores from... i need more infos for compare them .
I've been looking for reviews on the 7970M and haven't found any yet. In particular the 7970M vs 680M.

I don't understand what it is your asking exactly. Is not a score of almost P7000 pretty good for mobile non CF part? Or perhaps you have another mobile part that does just as well? Have a link?

First benches of 7970M: quite a good result against older generation from the competitor.

Thanks for the links. It also scores 7.6 in WEI. I've not seen a laptop score that high before
. The 7970M is looking more and more like it's using the newer silicon.
It can do 1010MHz? Really? Can you point me to any other mobile gpu that can do that?
Do you have information of how the chip was manufactured? Do you have a link?
The link you provided shows the result of an overclocked GPU (to about the speed of the desktop HD7870 which uses the same chip, i.e. it is not overly surprising that this clockspeed is possible). And here is some news: yes, you can overclock other mobile GPUs too. Not that it is relevant.
Do you have information about a new stepping or not? It was not me claiming the use of "the newer silicon", I was only asking you.
What I asked is if there is another mobile gpu that can do over 1Ghz OC using stock mobile cooling
. Gotta link for that? You should re-read what I wrote. I said it looking more and more like new silicon. What could you possible gather from that?Do you have information about a new stepping or not? It was not me claiming the use of "the new silicon", I was only asking you.
However you said
So I would like to know if you have any additional information about that (in particular manufacturing process). Do you have a link?
Using the same database your results came from and starting at the bottom of the last gerneration.What I asked is if there is another mobile gpu that can do over 1Ghz OC using stock mobile cooling
There are probably more. Even mobile Fermis could be overclocked to ~1GHz core clock (meaning close to 2GHz shaderclock). But I still don't see what this is supposed to prove.
Don't forget the definite article you used. It implied, that you know that there is something new (opposed to the use of an indefinite article which would imply a speculation). That's why I asked you.
But okay, we got that cleared up now.
So a 7470M can also overclock to 1Ghz, impressive. I thought there were others from last gen or from competition though.
:smile:, ok its clear you over analyzed my post a bit. I think we all are looking for more information from the mobile gpus. To me it's very impressive so far. IE: 1GHz clock rates on the 7000M series on mobile cooling solutions, power consumption, etc. I've done some more digging and found a 6970M review from the same website. The hardware isn't the same but it does give some indication on where the 7970M stands.Don't forget the definite article you used. It implied, that you know that there is something new (opposed to the use of an indefinite article which would imply a speculation). That's why I asked you.

i7 2720QM (3.292GHz) + 6970M (680/900)
i7-3610QM (3.195GHz) + 7970M (850/1200)

Yes the score is very good and I wasn't disputing that in any way. I was merely asking the reason for that particular comparison and pointed out some things in it, like the different CPU making quite a bit of difference there, 3Dmark11 really likes hyperthreading and only one CPU in your comparison has it.
PItcairn does look to be a very potent chip for laptops.
edit: It also wasn't very apparent from your post that you had realised the 7770 score being crossfired.
