Meet The Radeon HD 6670 & Radeon HD 6570

With the Redwood cards (5670 & 5570), we saw two distinct reference designs even though both used the same GPU. The 5670 was a full-profile card while the 5570 was a low-profile card intended to fill a higher performance low-profile niche. With the Turks cards however, this kind of stratification is gone.


Look closely and you'll see the ATI logo. AMD is using spare 5570 coolers for the 6570 reference design, which means these coolers predate the AMD rebranding. Retail cards won't be like this, however.

Instead both reference cards are low-profile cards. The PCB for both cards is quite similar, but not identical. In practice with only a 6W difference between the two cards, we can’t imagine too many partners will roll different PCBs for the cards. The difference between the two cards really comes down to the cooler used – the 6570 uses the same AMD reference cooler we’ve seen on the 5570 and 6450 (it is in fact a spare 5570 cooler), while the 6670 uses a new low-profile double-wide cooler. This is how AMD managed to get the 6670 out as a low-profile card as opposed to a full-profile card like the 5670: it’s shorter, but it’s wider.

Our 6670 is equipped with 4 2Gb 5GHz Hynix GDDR5 memory modules. This marks the first time we’ve seen 2Gb GDDR5 on anything other than a high-end card, which is a good sign that we should expect to see more cards using 2Gb GDDR5 in the near future. Both the 6670 and 6570 measure 6.61” long, the same length for that matter as the 6450.

Display connectivity is the same as with other AMD low-profile cards. On the PCB are a single DVI-DL port and a DP 1.2 port, while on the bracket is a VGA port attached with a ribbon cable. With partner cards we’d expect a number of cards to drop the DP1.2 port for an HDMI 1.4 port on both cards. But on that note, one thing we’re still trying to get confirmation on from AMD is whether Turks can drive more than one DVI-type display at once. We have no specific reason to believe this, but Barts did drop a DVI-DL port for a DVI-SL port, so if anyone is going to drop down to supporting a single DVI-type display at once, it’s AMD. In any case through the magic of DP1.2 MST hubs, the 6670 can drive four displays. Meanwhile the 6570 can drive three displays.

As was the case with the 6450, AMD’s reference design is only for engineering and sampling purposes – it’s not going to be used in retail cards. We don’t have any pictures of retail cards as of press time, but we’d expect 6670 and 6570 designs to resemble 5570 designs with a larger cooler more suitable for Turks. As such our temperature/noise results are a decent approximation of the cards that will be on the market, but they won’t match any specific retail cards.

    Courtesy of Hardwarezone (and Techconnect), here's a look at what many of the major AMD video card hardware partners have for us on release day:

    Highlights (for me): the HIS fanless 6570 and that dual-fan MSI 6670! I'm sure many more overclocked and exotic cooler models (like MSI Cyclone and HIS IceQ) are on their way

    The eternal question.

    I just read all the comments looking for something like this. Thanks for not letting me down. Ryan, nice TMBG reference.

    We know, we know. The article immediately reads "copypasta" when I see this. *sigh*

    Personally, I expect my next build to be used mostly as a work (browser + Office 2010) PC (no games) and to be used sometimes as an HTPC and -- very infrequently -- a video encoder since our only child will probably be more than 500 miles away, going to college. I am cheap, especially about electricity. My apartment is all fluorescents today and I am impatiently waiting for 5000K LED bulbs.

    Therefore, I may be looking at the 6570, or, more likely, the 6450. But what about the Sandy Bridge integrated 3000 graphics? Below, I have copied several paragraphs about the 23.976 fps problem from The Sandy Bridge Review, "A Near-Perfect HTPC." What is the current status of the software fix mentioned in the last paragraph? Is it available? Have you tested it?

    "What happens when you try to play 23.976 fps content on a display that refreshes itself 24.000 times per second? You get a repeated frame approximately every 40 seconds to synchronize the source frame rate with the display frame rate. That repeated frame appears to your eyes as judder in motion, particularly evident in scenes involving a panning camera."

    "How big of an issue this is depends on the user. Some can just ignore the judder, others will attempt to smooth it out by setting their display to 60Hz, while others will be driven absolutely insane by it."

    "If you fall into the latter category, your only option for resolution is to buy a discrete graphics card. Currently AMD’s Radeon HD 5000 and 6000 series GPUs correctly output a 23.976Hz refresh rate if requested. These GPUs also support bitstreaming Dolby TrueHD and DTS-HD MA, while the 6000 series supports HDMI 1.4a and stereoscopic 3D. The same is true for NVIDIA’s GeForce GT 430, which happens to be a pretty decent discrete HTPC card."

    "Intel has committed to addressing the problem in the next major platform revision, which unfortunately seems to be Ivy Bridge in 2012. There is a short-term solution for HTPC users absolutely set on Sandy Bridge. Intel has a software workaround that enables 23.97Hz output. There’s still a frame rate mismatch at 23.97Hz, but it would be significantly reduced compared to the current 24.000Hz-only situation."

    Anandtech, thank you in advance for your reply.

    For an office/browser setup. Any current technology will work just fine. My old 2009 ThinkPad runs Windows7 pretty good with a PDC 1.8Ghz (bottom end Core2) with crappy intel graphics and 2GB of RAM.

    The AMD Fusion Llano platform is pretty exciting and its not even the top-end bulldog. Its onboard graphics destroys intel and it'll help the CPU with other tasks.

    Sandy bridge is very good of course, so just add a $60~80 video card and you are ready to go. Sad we have to talk about todays CPUs by their code-names.

    ** Don't expect an answer concerning the 23.976fps issues. Call intel on that one. intel always had and always will have sub-par graphics. Check out HOW stupid Intel is.

    For the bottom end SB, it has the worst performing built-in GPU. The top-end has their best, which is still pathetic compared to the graphics built into AMD chipsets. Logic should dictate that the person who spends $500+ on a CPU, is most likely going to have a dedicated video card - DUH! Even a $40 6450 will smoke any built-in Sandybridge graphics. Its the entry level systems that need better graphics.

    Has anyone actually seen a low-profile 6670 offered for sale anywhere? I see only a small handful of full-height cards when I search.
  • Taft12 - Monday, April 25, 2011 - link

    No OEM ever made a low-profile 5670 and I don't imagine there will be a low-profile 6670 either.
