Test Setup And Benchmarks

Benchmarking AMD's 768-Shader Pitcairn: Not For Public Consumption
By , Benjamin Kraft

For this review, we're using the same hardware that also helps us generate our VGA Charts, giving us consistency across a wide number of cards and, consequently, a large number of competing products for the sake of comparison. There 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.

2012 Graphics Charts Test Bench
CPUIntel Core i7-2600K (Sandy Bridge), 3.4 GHz @ 4.5 GHz (45 * 100 MHz), LGA 1155, 8 MB Shared L3 Cache
CPU Cooler
Prolimatech SuperMega plus Noiseblocker Multiframe
MotherboardGigabyte Z68X-UD5 B3, Intel Z68 Express
RAM2 x 4 GB Kingston HyperX DDR3-1600
System Disk
Kingston V100+ 256 GB SSD
ChassisCooler Master Lab
Power Supply
Corsair AX1200
Operating System
Windows 7 Ultimate x64 SP1


In the same vein, we are also drawing on our gaming benchmark suite used for the VGA charts. Rather than testing with all three of our current presets, we chose the one most relevant to this card, namely Performance. You can find the specific settings used for each benchmark in its corresponding chart. For more information about our methodology, feel free to check out our article Meet The 2012 Graphics Charts: How We're Testing This Year.

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

    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 really like this sort of investigative journalism. Two thumbs up.

    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?
