Benchmarking AMD's 768-Shader Pitcairn: Not For Public Consumption

Benchmark Results: 3DMark 11 And Unigine

3DMark 11

As usual, we kick off the benchmarks with Futuremark’s synthetic 3DMark 11. This is the only test in which we'll run all three presets, and we see the dip in performance typical of GCN-based cards at the Extreme level.

A card with these specs was never intended for this test's Extreme setting. Using more conservative options, the 768-shader Pitcairn-based sample beats Nvidia's GeForce GTX 560 Ti by a small margin. We consider that to be quite an achievement considering 3DMark 11 tends to favor Nvidia cards.

Unigine Heaven 2.5

Unigine’s Heaven 2.5 paints a similar picture, with our Pitcairn engineering sample coming in just ahead of Nvidia’s GeForce GTX 560 Ti, nearly putting it on par with a Radeon HD 6950.

Unigine Sanctuary

In Unigine’s Sanctuary, the engineering sample can even beat out a GeForce GTX 570, although we should mention that cards based on AMD’s new GCN architecture generally do very well in this benchmark.

Meanwhile, AMD’s previous-generation cards fall to the back of the pack, even ending up behind the Radeon HD 7770. Speaking of which, the HD 7750 interestingly comes in ahead of its bigger sibling. We’ll chalk this up to a driver issue for now, and re-evaluate performance using the next driver update in the course of our normal charts revision.

    i want one, that a amazing place in performance and probably only be $200

    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.

    while a nice card, the 6850 is incredibly close and nearly $60 cheaper, the only thing is it does consume more power
  • borden5
    oh man that single slot would be really nice for people who wanted small factor rig
  • slomo4sho
    Wouldn't 2 7750s in crossfire perform better than this rig and also consume less power at the ~$200 price point?

    Maybe, depending on your local market, but the single slot and price point is the whole point to this...
  • Say hello to the AMD HD Radeon 7790.

    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*.
  • Doesn't the 7770 have 40 Texture Units and not 14?

    now bring the game..

    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!

    NivalisSay hello to the AMD HD Radeon 7790.

    Give single slot card so we can revigorate our minimalistic solutions with extra power for when diablo III arives.

    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.

    want one, cant afford the 7850! $160 should do it justice.
  • Rattengesicht
    Do it AMD ! You know you want to ;-)
  • Maximus_Delta
    I really like this sort of investigative journalism. Two thumbs up.
  • Darkerson
    I guess we'll just have to wait and see if they change their mind and release it eventually. Would be a nifty little card with a more affordable price tag.
  • esrever
    Anyone else notice that the 7970 and the 680 are trading blows? And it seems that they are pretty even?

    this should me HD7790

    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.

    Ouch, has that ever happened to another board in your lab?
  • youssef 2010
    I think AMD should mass produce the GPU. After all, it the company that invented the sweet spot strategy.
  • redeye
    why not just send it back?. but since you love Nvidia, it will not make a difference if the next new AMD card is on a slow-boat-from-china...
  • ScrewySqrl
    pretty much right where I predicted it would sit in my comment on the original news article yesterday. This would be a GREAT card in the $180-200 price point.
