Default The HD-7700 Does'nt look to good unless it is a rummor

IT is supposed to have better GCN Architecture and bigger Stream Processors but the spec's they show don't look to impressive with a 128bit buss and just 72.GB/s compared to 264GB/s of the 7970 384bit buss.2048 stream processors to 640 ,It will have 1 gig of memory running at 1125 {4500} compared to 1375{5500},It has16 ROPs compared to 32.It is priced around $140.Unless this is just a rumor,who knows it looks like it could be real.Click image for larger version

When I saw this I did not see any reviews ,after looking at the review ,it does'nt do so bad .It only uses 80 watts which is great and it is faster then I thought it would be .AMD should price these at $129 since it loses to the HD6850 which is around the same price at the moment.The closest card nvidia has against it is the old GTX460 and the HD7700 beats it nearly all the time.Right now AMD is in contest with itself since there are so many that run around the same.But it is a nice entry card with DX11.1 support and uses 80watts and can run in crossfire.I just think if they would price the HD7700 at $129 and the 7750 at $99 It would be a better deal ,but at the moment they have no competition.Good for AMD{ATI}

Why doesn't it look good? It beats the comparably priced GTX 550.

Why are you comparing it to a card that is almost 4 times the price?

It's going to perform better than 6850 in many cases reports are saying (not mem bandwidth limited cases obviously), so in my book, that's a win for $150.

EDIT: didn't see that review above... I wasn't expecting reviews just yet. Looks decent for the mid range card, sometimes neck and neck with 6850 and 5850. Considering it has almost half the memory bandwidth that's a damn impressive feat. It does need to be priced right though, just like the 5770 costing more than the 4870 at launch, but then becoming the better buy after a few months due to price and drivers getting better for it. Drivers will make even more difference here as GCN is a new architecture.

A GCN vs VLIW-5 comparison, clocking 7770 at 5770 clocks.

http://ht4u.net/reviews/2012/amd_rad...est/index4.php

Pretty interesting, looks like it averages around 10-20% better despite having only 80% of the theoretical flops.

Considering the price is the same as the 5770 when it launched in 2009, the performance is a little underwhelming. An extra CU and faster memory would have been welcome I think, still it's a solid performer for the low power use.

GCN doesn't scale well, honestly i am dissapointed with 7xxx series completely.

Strange? It's a budget card. It's priced comparable to a GTX 550, which it seems to beat easily. Overclocking brought it close to the GTX 560, a card that's $50 more.

They have just a nice line-up for the high-end market right now. And this budget segment is the most important one... The card is just a bit underwhelming in my opinion.
I agree, it's a bit underwhelming, but it's priced at $150, not $200-$250. And it beats its competitor at the same price point.

I would expect the HD78xx series to beat the 560 Ti at a comparable price or a little cheaper. My guess is 7870 will beat 560 Ti, 7850 will beat 560. Of course, those are just guesses.

You know that's what the 7800 series is for right?

Right. I'd be disappointed too with a product that beats its competitors for cheaper.

Rumor for HD78xx series release is March. Apparently vendors are getting creative with 7950 variants too and getting some crazy performance out of them.

GCN doesn't scale well? Did you not read the link in my post above yours?

http://ht4u.net/reviews/2012/amd_rad...est/index4.php

Up to 30% more performance at the same clocks with 20% less FLOPS. Sounds like it's scaling fine, the limitations are in the memory.

Maybe they could have gone with a couple of extra CU's and a 192-bit bus. IMO they should have, but this is still a strong product, the price will just need to come down a bit more once NV releases, same as 79xx.

One issue is the very low pricing from the 6850 and 6870. The better performing 6870 can be had for nearly the same price and the 6850 is even less.
