Posted the images of the slides I got a hold of at IMGUR for you all to see.

From what I got on early benchmarks is that the 7850 is a little faster than the 6950 and the 7870 is a tad quicker than the 6970.

I'm a little iffy on the benchmark information as I didn't get full system specs regarding them, but the two cards were compared to the previous halo cards.

Battlefield 3: 1920x1080 4xAA
6950 = 28.6
6970 = 32.5
7850 = 30.1
7870 = 35.9

Crysis 2: 1920x1080 4xAA
6950 = 29.9
6970 = 33.1
7850 = 32.4
7870 = 39.0

Metro 2033 1920x1080
6950 = 28
6970 = 31
7850 = 29
7870 = 33

My source didn't have the system specs, but I'm impressed enough to upgrade to a couple of 7870's from my 5850's if the information holds true.
 
No pricing was directly provided to me, but from I hear, it's looking like the 7850 will be priced at about $199-$220 and the 7870 will be priced around $270-$300. AMD is supposedly working on BOTH a 7890 and a 7930 both based on Tahiti to bridge the price between the 7870 and 7950. However, if nVidia GK104 does prove to perform well compared to the 7950, and is priced at the 7870 level, AMD may just go with the 7890 and lower prices across the board.

If those price are accurate, it is going to be very hard for me to decide between the two. The 7850 looks like it will be a shorter card which means I don't have to hack my case up at all... but for the extra money, it looks like it is considerably more performance.

Have to wait and see for some real reviews. As it is right now, I plan on pulling the trigger as soon as they become available.. once I decide on a brand..
 
If the 7870 is a tad faster than the 6970, that puts it in GTX 580 territory - and if it is priced at $300, that is going to make the 7950 look pretty overpriced.

7950 is over priced.

$279.99 for 7870 will be a very good card for the money.
 
So...

7850 = $249?
7870 = $299 ?
7890 = $349 ?
7930 = $399 ?
7950 = $449
7970 = $549
 
I'm looking for a reasonable upgrade from my Radeon 5800 series- (gearing up for Mass Effect 3)

After reading your positive review on the XFX R7770 Black EditionI figured it would be a nice
upgrade.
But-
Do you guys think the 7850 would be a substantial enough improvement over the 7770 that I should wait a few weeks for them to be released and go with it, or do you figure the 7770 would take care of me for another two years or so?

I play at 1080p, and I'm not replacing this rig anytime soon, so whatever I put in needs to remain viable for, say, two more years. The 5800 series has been competent enough, but I've begun having major lockup problems when playing Fallout 3 and some other games- it's time to retire it and upgrade.

What do you think?

Sounds about right, but if GK104 performs at 7950 levels.

7850 = $175
7870 = $250
7890 = $300
7950 = $350
7970 = $420

Their wouldn't be room for the 7930, but honestly, I hope that GK104 kicks ass, because these prices are what the cards should really be at if AMD GPU history is used as a guide.
 
Figure the 7850 performs a tad quicker than a 6950. The 6950 demolishes both the 7770 and 5850. On top of that the 7850 has 2GB of ram. I have two 5850's in Crossfire and two 7850's would be an AWESOME replacement, but I think I'll go with a pair of 7870's. They should crush a single 7970.

A $100 price drop on a 7950 would be awesome. I would have definetly picked one up already at that price.

it'll put it some where between the 570 and 580 pretty much. the 6970 while it went back and forth with the 580 in some games the 580 was pretty much faster then it by a decent margin in most games. while the 7950 i agree is priced a bit high, i still think there are a lot more improvements AMD can make at the driver level for GCN so the gap widens between the 7870 and 7950. i said in the beginning and i'm sticking with my prediction that by the time AMD figures out what the heck they are doing with the drivers we should see at the minimum a 20% performance improvement over the next 6-8 months at reference clocks.

LOL...Sorry but I don't think they're going to drop the 7970 by $130.

I mean, it SHOULD be dropped by about $100, but I just don't see that happening.

I don't know - it's not like AMD is known for their driver prowess. You might see that is some games, but I'd be surprised if it was across the board.

Yeah, I also think they days of massive overall performance increases via drivers are over.
 
These 7870's look good imo, pending price of course, but I like what I see so far.

20% sound optimistic to me, I would estimate ~10%. They have already improved slightly with the 12.2 pre-certified drivers.

According to tom's a 6850 is enough to run Mass Effect 3 at 1080p even while forcing MSAA (this can only be done on AMD at the moment).

I agree with you ..... i would expect no performance increase :)
comparing HD 7870 vs HD 6970 (if benched at the same core speed with the latest drivers) (got this conclusion from looking at the number of SPs)
 
So now I will just have to wait for Kepler, then once all the prices have been totally set I can swoop in and grab a pair of 7870's.
 
Hopefully Kepler is good, so the AMD prices go down a bit. A 7870 at around $250 in the near future would be awesome.
 
I wish sure these would be launched.


I would like to replace my 6870's with 7870's

A 5870 is faster then a 7700...

yup. the 7770 is slower than the 6870 (not by much) Which means the 7770 is also slower than the 5870.

still the 7770 is a decent card for 1080p for today's games. the 7850/7870 should be faster than your 5870 by a decent margin.

a 7770 is not even as fast as the 6850. its only about 25% faster than the 5770/6770. that actually makes the 7770 closer to 5770/6770 than to the 6870.
 
Upon further review, the 7770 does seem pretty mild after all. It's been two years since I have paid any real attention to advancements in GPU's, so I hope I don't sound too ignorant. Should'a done some more homework before posting.

I remind you that my 5870 is hanging up pretty bad lately- that's the reason for the desired upgrade sooner than later- I'd otherwise just play ME3 on the 5870 and upgrade when I new-system.

Bottom line is I won't spend more than $300 for the next card. I'm totally willing to hit the $500+ threshold when I do full-system upgrades, but for a mid-stream swap like this I just can't justify it-

Sucks a lot that ME3 is coming out now and the next-gen GPU's are a month away.

I want to bridge the next two years as best I can.

Which makes sense if you think about it, except the fact that it costs WAY more.

I think the 7770 should have been much faster though. around 25% faster than the 2.5 year 5770 is not much progress at all.

True, but apparently that's how we do things now, right? 25% stock gains over a 1-2 year old product?

:p

:rolleyes:
 
I'm interested in seeing the power/temp levels aside from a full performance review, of course :D
