Upcoming GPU Info Thread - 6xxM / 7xxxM Discussions!

So recently AMD released the 7000 series which are made on the 28nm process.

I went to look over power consumptions cause that is the best indicator for which GPU will be used for mobile cards.

Since the 6990M was running at 100W and was based on the 6870 core. I assumed that the card which will be used for the flagship of the 7000M series will have similar TDP as the Desktop 6870.

The card that best matches this criteria is the 7950, which does consume a little bit more than the 6870, but it's very close to it.

Thus, the next thing to do was to look at power efficiency, and the 7950 is between 20-25% more power efficient than the 6870.

My conclusion is that the 7990M series or 7970M, whichever AMD decides to call it's next flagship mobile card, will be 20-25% faster than the 6990M, having the same TDP.

Enjoy!

 

Yes that sounds logical. It should be a fun summer with the latest flagships from AMD and Nvidia.

Yep, can't wait, it's going to be awesome, we'll definitely see a lot of benchmarks and tests by that time.

@Blacky
Nice comparison, you sure seem to have you facts placed firmly

 

we see hd7770~vliw4 28nm~tdp 80w, its performance=hd6850=hd6990m
so vliw4 28nm 100w card......

but nvidia's flagship maybe dont like amd use old vliw4 but new kepler, hope can see 680m~~=sli 580m big boost

 

Looks like we will neither see Ivy nor Kepler before Q4 after all:

Intel 'Ivy Bridge' chip delayed, Windows 8 in September, report claims | Business Tech - CNET News

Nvidia comes somewhat clean on their quarterly conference call | SemiAccurate

 

That is according to leaks, we haven't heard anything official yet. Lets wait, I reckon a good Q2-Q3 release.

 

No Radeon 7700/7800/7900 uses old VLIW4, they're all GCN. It was a stupid rumour to begin with that almost nobody took seriously (besides AMD-haters and Fud) and now that the cards are out everyone can confirm that it was a bunch of crap, get up to speed.

 

Uh... the 7950 is rated at 200W, ~50W more than the 6870.

I can't see 7900M coming from anything but the desktop 7800s.

 

No no, read this:
AMD Radeon HD 7950 3 GB Review - Page 25/31 | techPowerUp

Average power consumption is 126W (for 6870 it was 119W).
Peak power consumption is 144W (for 6870 it was 128W).

I guess the 7950 will need a bit of trimming, but it's very close.

I suspect that when the 7870 will come out, we will also be looking at the flag ship GPU for notebooks.

 

Not even sure if the 7970M will be a 100W part. Possibly 65W/75W. Pitcairn is supposed to use 120/90W on the desktop side for the 7870/7850. Tahiti Mobile is unlikely.

 

Well, Nvidia is going to come out with a 100W video card and AMD will probably do the same.

I'm pretty sure 100W is the standard for high-end video cards right now.

 

6970 is a 75W part. Maybe the 7990M will be 100W.

 

The 6970M was more in the range of 85~90W.

And I'll be greatly disappointed if Nvidia and AMD don't push the 100W barrier again. There's no reason to leave performance on the table, now that Alienware and Clevo machines are being built to handle cards that powerful.

 

It's kind of hard to only focus on the Alienware and Clevo machines for them, after all they aren't their biggest source of income, although they are a large part of it. Power could always be pushed to the limit taking the power erformance ratio in consideration, but again those large power supplies ain't the best thing that comes with the laptop

I hope you understand what I mean, I'm really bad at expressing myself from time to time.

 

I would like to see the tech advanced rather than puting much hotter components into the gaming laptop! 100W is plenty for a graphics card of that size and if vendors push the limits to 130-150w it should interfere with desktop market and nobody needs that) jaug1337, agreed about power bricks! As we can see the smartphones are getting thinner and faster, ultrabooks more popular i dream to see the Macbook pro style laptop with P270HM power inside in future with a single slim 200w power supply, IMHO!

 

I completely agree!

The current power bricks used my Clevo me off, after so many years of tech advances, I am still dragging a huge brick around with me.

 

Sorry to disappoint, but I don't think there will be any reduction in size of power brick, they will increase the transistor count for better performance at the same watt.

 

Yep, the only time you'll see manufactures decrease wattage is when they're intentionally throttling their chips in order to increase battery life; which will only occur in mobile platforms.

As better architecture and programming get released, manufactures will take advantage of the extra power gains in order to increase their clock rates and thus get more speed in order to compete.

Higher Watts = Higher MHz = More Heat. It's a vicious cycle, and we love it

 

my question is how will this work with a model such as the p180 that supports the 6990 in crossfire? i believe its 75 watts? the 580m pulled too much current at 100 watts, so does that mean the p180 i just ordered wont likely be able to support the newer cards in crossfire/sli configurations? that would be a major disadvantage to me ordering now and id consider canceling and reording when these come out

 

The P180HM is now considered EOL (End OF Life) by Clevo. It will receive no future hardware or software updates, beyond what you see now.

It's officially dead.

 

so should i not order it then?

 

I think the general consensus right now, is to wait for Ivy Bridge.

From a warranty standpoint, if the laptop fails in three years it might be more difficult to get parts, and therefore more expensive to repair for discontinued models.

 

the thing with waiting for the ivybridge, its already been said the p180 will not recieve an ivy bridge update, so even if i got an ivybridge model, it wouldnt support SLI or crossfire from the looks of things, and i would be sacrificing overall performance

 

I also suggest waiting for April 2012. I will make my decision then on what to buy.

 

you have the p270wm

 

CeBIT goes from March 6 to 12; we should receive a substantial amount of information on upcoming machines at this conference.

 

lets also see gt650m big improve
vantage p10000(no physx comfirmed)

650m in clevo w110er 11.6"(tdp 45w thus single heat pipe)

 

That looks like a sweet little machine. I wonder how the battery life will be.

 

Awesome performance. The 660M will almost be like 580M

 

AMD's upcoming Pitcairn GPU detailed

 

wow thats insane, P10,000 in an 11 inch laptop!!! :O

damn this is gonna be an exciting summer indeed

 

Keep in mind that the Vantage score shown for the 650M is not specifically the GPU score.

But, as long as they were all tested with the same CPU, it is indeed a large leap from the 555M.

Hopefully it works out similarly to my initial prediction, which had the 1408 shader part becoming the 7970M.

Then a cut down 7890 (lower the memory interface to 256-bit) could be used for the 7990M.

 

Kevin...what you are saying is we won't have a 256bit AMD gpu on ivy bridge launch..like the 6970m was for SB

 

We need to see the TDP to know how things will work out.

At this point it seems that a slightly trimmed down version of the 7950 (it could be the 7890 or the 7870) will be just right for a 100W TDP mobile card.

 

@paradigm: no, he just said that the 7890 would be cut down to a 256 bit mem interface, compared to its 79xx counterpart based on the same chip. the other 78xx series cards will be based on the pitcairn chip instead of tahiti and will sport a 256 bit mem interface right from the start (meaning this spec wouldnt have changed from the original chip design).

cheers

 

^Correct.

The 7870 and 7850 are 256-bit, and are a given as the first 7900M GPUs.

The 7890, on the other hand, sports a [rumored] 384-bit bus, which would be unprecedented (probably impossible) for mobile chips.

It's also very possible that 7870 = 7990M, 7850 = 7970M, but that's less exciting.

 

do you have any confirmation? This seems too good to be true, that power in an 11.6 inch notebook?

Do you have any sources?

Who would even need that power in an 11 inch notebook ^^

 

m11x, although quite large and thick, its supposed to have some kind of power.

I actually like this trend of smaller and more powerful, I would like so much that apple could make something like that to the mbp13.

Although I would only buy the air from now on

 

Neither would I.

 

Here is the source (I think) if anyone is interested. And the people there say that the 10 000 score is incorrect.

Google Oversetter

 

btw here are some more pictures of the 11.6 inch notebook and the insides

 

Way too much thread crossover going on in my subscribed threads, so let's keep the 650M discussion in the 660M thread.

Blacky probably doesn't want this here.

 

Okay so the 7950 uses a little bit more power than the 6870 (of which the 6990M is a downclocked version of) and the 7870 will undoubtedly use less power than the 6870. Here's what I'm hoping for:

7970M: Straight up 7870 chip, maybe a tiny bit downclocked.
7990M: Downclocked 7950.

Wouldn't that be awesome?

 

It is possible, and yes, it would be awesome.

 

if this is what ends up happening I will switch my 6990m for a 7970m in a heartbeat. (though most likely I would just end up replacing the whole laptop for an IB variant.)

 

Looks like there's also going to be a desktop 7890. Probably the more likely scenario is the 7870 becoming the 7970M while the 7890 becomes the 7990M.

 

Huh, a non-upgradeable Clevo?

 

Upgrades are still possible, you're just limited to the tech it has now. Clevo's are upgradeable, but the problem comes when new sockets or standards are introduced that it wasn't designed for or shipped with. When that happens, your upgrade path gets truncated to the latest hardware before the change.

The same goes for laptops that happens to desktops. If your P4 desktop with an AGP graphics card is in need of an upgrade, you have to gut the whole thing and replace all the internals (including mainboard) to get a Sandy Bridge CPU and PCI-E graphics card. Upgrades are great, but they're not always possible when there's a radical change to the hardware.

 

Clevo will not officially offer or support any future upgrades to this particular machine. That's what EOL means.

That doesn't mean a 7000M won't plug in and work, it means you're on your own with any issues.

 

Maybe we should find a professional to bios-mod and make your own support?
I'll pay someone $ 500 for implementation of the XTU in the P150HM.
