I would never buy this card for myself but I would find myself recommending a 1GB model, like you mentioned, to family and friends. If the price is right AMD could have a great mid range card.

Maybe, depending on your local market, but the single slot and price point is the whole point to this...

This card would be an AMAZING pick for an HTPC, Single slot, Low power, 2gb DDR3 for HDTV's, not to say 1gb wouldn't be okay. But really AMD, do it up! All of this positive feedback is great reason to make a crippled 7850!

This card performs great and a 1 GiB version selling at ~$200 would fill in a very large gap in the market. It would only make sense if AMD is cooking up something they'll likely call a 7830 to do just that. I guess though it would differ from this engineering sample if they're so insistent that they aren't bringing it to market. Maybe it'll have less texture units or ROPs.

Still this card with 1 GiB at ~$200 would be pretty sweet AMD *nudge* *nudge*.

A "7830" with 1GB of VRAM priced to compete with the 6870 or 6930 (if you have that in your country, the USA doesn't) 1GB cards would be great. If anyone wants a new card between the 7770 and 7850 in performance (basically, between a just short of a 6850 and just short of a 6970), then they're screwed because there is no middle point. They have no choice other than buying an old 6870, 6930, or 6950.

With a 1GB model at $185 to $195 and a 2GB model (2GB is far better than 1GB for Crossfire setups at higher resolutions/quality/AA/AF) at $210 to $220 would be good. Also, 7830 is the best name for this, at least in my opinion. All that would need to be done is bringing down the power usage a little (need is a strong word for this, that it is lower than the 7850 is still a great improvement over the 5830 and 6790 fiascoes). I would like to see a 100 to 110 watt TDP, rather than a 120w TDP (sure, TDP does not equal power usage, but still). Even without doing that, it still uses less power than the 6870, so it's acceptable. However, if Nvidia makes a competing card (looks like they will), then Nvidia would probably undercut it by at least 15 to 20w.

Regardless, come on AMD, release this as a 7830 or something such as that! It's a great card and it fills a market that is almost desperate for a refresh!

You mean the 6870, not the 6850. If more games were included, we would see the 6870 closer to this hypothetical 7830 most of the time. Keep in mind that Tom's tested a 2GB model, so you would have to compare it's price against the 6870 2GB for a fair comparison, not the 6870 1GB.

ArticleThere is one small change to note: as a result of the wear and tear associated with constantly switching out graphics cards, the x16 PCIe slot on our Gigabyte Z68X-UD7 B3 literally came off the board. We are using the Gigabyte Z68X-UD5 B3 in its place, giving us identical performance.

I'm right at that point where I need to build a new gaming rig, and will be doing so (hopefully) within the next 12 months. This is exactly my target price/performance range. I know I'm not the only one in this situation, and if AMD neglects this demographic while nVidia releases a card at this level then AMD will be losing out on a huge chunk of the market share. I simply can't afford to pump $250+ into a GPU when my goal is for the PC to cost $800-1000 (and I want good overall performance as well). It is completely up to nVidia and AMD who gets my money at this point.

Since everyone's pretty much said enough about the "7830", and i agree with all the positiveness, i won't add anything else.

What i will say is something i hadn't ever noticed before: The 560 and 560 Ti are at par? What 560 have you guys used? Is it OC'd?

Also, +1 to the 680-7970 effective tie.

Looks like a good GTX 560/Ti contender. However, AMD must keep in mind that NVidia can probably release a 660/Ti at moment's notice to counter this with better efficiency and performance.

At least not while the 7850's are selling well and they dont have a stock pile of those chips. Later on if the 7850's sales lag, they make too many, or if there is a large demand in the segment, they may very well re-badge some of them as 7830's and go from there. It looks like theres obviously a market for the card, but it may not be worth the money and time to introduce this variant, at least not yet.

If AMD did this, it might well be a real kick-in-the-teeth to NVIDIA, but it'll also take attention away from the real 7850. Still, I'd buy one to replace my aging 4830 (which it reminds me of all too well).

I was automatically thinking of a 7850SE, however AMD have pretty much long since abandoned any SE moniker cards and are more likely to bring out a 7830 (NVIDIA are far more likely - the 460 and 560 series plus the all-too-alarming-GT640s). Any 7840 or 7860 that appears would be an OEM card if past history is anything to go by.

Name it the 7830, sell it for $190, and you've got a winner. It would be a good replacement for the 6800 series cards. Once AMD accumulates a lot of chips that won't make it as 7850s it would make sense to sell such a card.

Yep, but I think they don't want to make a 200$ card because the 7800 are overpriced (due to lack of competence) so when the new nvidia line comes up, they will be able to put the 7870 at ~270$ and the 7850 at ~190$. that's what I think...

Two low end cards almost always are more energy efficient and cheaper than a single higher end card. For example, two 6770 2GBs in CF are almost identical to a single 6970 in performance, but they use a good deal less power and are cheaper. 6770s are also cool because there are dual CF dongle versions that support triple and quad CF :)

Well, the relation of this card to the 7850 is similar to the relation between the 6850 and the 6790: A cut-down version of the pricier card that uses almost the same amount of power. AMD hasn't done an xx30 model in quite a while. So I'm comfortable calling it a 7790.

But this is all hypothetical anyway. We can call it an HD 7824 if we want.

AMD did the 5830 right before the 6790. Is just one generation prior too long?

I'd rather call it a 78 something rather than a 77 something because that implies that it is more similar to the other 7800 cards than it is to the 7700 cards (which is true). 7830 came up because that was the usual moniker for these cards (5830, 4830, 3830) and the 6790 was the odd one out.

This card would be magic if it sold for 150-180 at 1.5 gigs of vram.

CF that would yield a monster in BF3 maxx AA. As a single slot, in CF the space would let you keep things cool. I see more 800-1000k builds than any other type. Given the costs of hard drives that tends to mean a i5/z77 w/ a gtx 560ti/480/570 or a 7850.

It has a 256 bit bus. AMD doesn't seem to yet have the ability to have memory capacities that aren't in line with the bit widths like Nvidia does on their GTX 460 192 bit 1GB cards, so AMD is stuck with either 1GB or 2GB as their only reasonable choices.
