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

Benchmark Results: Mafia II, GTA IV, And Batman Arkham City

Mafia II (DirectX 9)

Despite the progress we saw in Crysis 2, it looks like AMD still has some driver optimizations to tackle in a few older DX 9 titles. In the end, this has little impact on actual playability at our test settings, with the mystery chip turning in smooth frame rates. We would have expected some of the GCN-based cards to turn in higher numbers, based on the previous results, though.

GTA IV: Episodes from Liberty City (DirectX 9)

As in Mafia II, the Radeons finish just behind their GeForce counterparts, albeit by a slim margin. On the whole, all of these results are pretty good for a halfheartedly-ported console game.

Batman: Arkham City

Since the Radeon HD 7850 turns in unusually low numbers here, it’s only natural that its pared-back little sibling falls behind as well, placing behind the Radeon HD 6870 for the first time in this story. Still, the frame rates are still easily sufficient for smooth game play, although we wouldn’t mind seeing a few more driver tweaks for this title that seems to prefer Nvidia cards at the moment.

    oh man that single slot would be really nice for people who wanted small factor rig

    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*.

    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

    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...

    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!

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

    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!

    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.

    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.

    Anyone else notice that the 7970 and the 680 are trading blows? And it seems that they are pretty even?
