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

[Blacky]

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.

[Blacky]

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.
