[citation][nom]wolley74[/nom]while a nice card, the 6850 is incredibly close and nearly $60 cheaper, the only thing is it does consume more power[/citation]

What do you expect from an Engineering Sample?
 
hey! its a good idea. By now im having a HD6790, thats everyone knows it's 6850 crippled. It works pretty good, and it is quite better than the 6770. It was *MY* perfect card for my budget at the time, and a 7790 or 7830 would be a nice upgrade for people that has roughly 200 at hand and cant go upper but also dont want a 150 card... As maybe myself in a couple months lol ! I saw the launch of 7770, then the 7850 was a huge upgrade over it and i was disappointed because there no was a middle one and i though i had to go for any nvidia card for 200 bucks as my next upgrade...
 

That might be so, but then you have to deal with micro-stuttering on the low-end CrossFire cards. You might get equivalent overall frame rates, but you won't get equal overall performance.

Additionally, buying two low end cards for SLI/CrossFire means you are stuck at that level. You have to replace to upgrade instead of having the option to buy a second card down the road to SLI/CF with the single, higher quality card.
 


Read the last sentence in my post. There are dual CF dongle 6770s that are capable of triple and quad Crossfire. The post that I replied to mentioned that wouldn't two 7750s in CF beat this hypothetical 7830 and I explained that that is normal.

Also, with the dual dongle versions, triple Crossfire pretty much eliminates the micro-stuttering problem. In fact, you only need one dual dongle version and two single dongle versions for triple CF and two dual dongle versions with two single dongle versions for quad Crossfire. So, buying a one dual dongle version can be a starting point for getting up to triple CF and that would challenge the 7950 and GTX 580 for performance.

Also, micro-stuttering doesn't always happen, even with dual GPU setups. It only happens some of the time and usually only in specific games.
 
[citation][nom]scrumworks[/nom]That is because Don didn't do the benchmarks this time. These two guys should do the benchmarking from now on.[/citation]

And all the tests are done on the "golden" 680's resolution of 1920x1080, where it should be king of the hill. 3dmark and synthetics are very well optimized for Nvidia, have fun playing those.
 
7830, 180-190USD and I will upgrade this generation. I have a 5830 currently which is fine for my needs. However two of these single slot cards would be very welcome in my workstation.

The best thing is the combination of performance, (expected) price and SINGLE SLOT design.
 
Bigger is better and i'm not energy savvy either allready running 1000W power supply 24/7

I always believe in buying the biggest best card I can afford and then a year or two later upgrade to a second one on the cheap. But then again I'm not one of the frequent upgraders like some of the people I see online. Adding a second card and a lot of overclocking buys a lot of time on my systems. This stuff is expensive and I always make sure to get my moneys worth from everything. It's why I got a 1000 watt PS because I don't want to have to replace it for a long time.
 
I think that AMD might be better off if they make a new GPU instead of using a third tier Pitcairn. Think about it. Even if this *7830* is made, it is only one level between the 7770 and the 7850, which are similar to the 6850 and 6970 in performance. They have the 6870 and 6950 between them, so it might be better if we have two cards between the 7770 and the 7830. So, we could have the 7830 that is close to the 6950 and a 7790 that is close to the 6870, with the 7790 being a second tier of the 7830.

This would both close the gaps more and eliminate the issue of using a third tier GPU (or, some 7830s can use either the new chip or a third tier Pitcairn, if there are a lot of them that fail binning to become even a 7850). Is anyone still checking this thread and considering adding thoughts to this proposal?
 
This is the card I'd buy, though not necessarily single-slot. For various reasons, including some nVidia driver anomalies I'm experiencing (have already gone through wipes and multiple re-tests), I am looking for something to replace my GTX560Ti. While the HD7850 seems the obvious choice, it is uncomfortably expensive. At the same time, all the reviews I've read have been rather unhappy with the HD7770; although its price has dropped considerably, it is still a little weaker than I want.
Anyway, since AMD didn't say "Ok Tom's, you got that by mistake, do NOT discuss it, benchmark it, or otherwise "leak" any information; send it back RIGHT NOW," I can't help but hope that AMD is indeed planning to release this card.

If you don't mind overclocking, a 7770 could be able to almost catch a 560 TI in gaming performance if you give it a good overclock. If AMD doesn't release a 7830, then it might be your best course of action if this is the performance level that you want should Nvidia also fail to respond to this price range properly with Kepler.
 
[citation][nom]jtt283[/nom]I do mild-moderate overclocks, but judging from http://www.anandtech.com/bench/Product/536?vs=547 I would need one quite extreme to catch a GTX560Ti. Even if Kepler perfectly fills the price/performance sweet spot, I don't think I can go that way since my issues seem to be software-related. I may consider Crossfire, since it would be easy to buy one card now, and a second in a few months.[/citation]

Radeon 7000 cards with a GCN GPU (such as the 7770) are great for extreme overclocking. However, if you don't want to do that, then either an older generation card, or like you said, Crossfire of AMD's 7750s or 7770s, would be your best options. However, they wouldn't be very upgradeable because they only support up to two cards for CF. Two 7750s would be very close to a 560 TI or GTX 570 in performance and two 7770s would be close to a GTX 580 or Radeon 7870.
 
[citation][nom]jtt283[/nom]I've seen the benches on the Crossfire of those cards, and they do look good. One thing I like about them is how little power they use, and too high an overclock sort of defeats that.[/citation]

Not really. Even overclocked to the max, a 7770 would still use less power than similarly performing and most slightly slower cards. They would still be more energy efficient than similarly performing graphics configurations made from older cards. However, I didn't include overclocking in those performance comparisons from my last comment because you said that you didn't want huge overclocks, so don't worry about that.

With big overclocks, those 7770s in CF could be ridiculously powerful for a setup made from lower mid-range cards. They could surpass the 7970 and probably even the GTX 680 by fairly good margins if they had big overclocks. That's probably at least part of why AMD doesn't make reference low end cards that have more than one Crossfire connector.
 
Posting this in 2013, two weeks away from Computex Taipei, its mind-blowing that AMD was working with Microsoft and Sony this far back on what would eventually become Bonaire and give life to the PS4 and Xbox One. Tom's, you can take the credit for being the first website to see the inner workings of either console just over a year before! What a brilliant strike of luck.
