Meet the Rest of the Evergreen Family

Somewhere on the way to Cypress, AMD’s small die strategy got slightly off-track.

AMD’s small-die strategy for RV770

Cypress is 334mm2, compared to 260mm2 for RV770. In that space they can pack 2.15 billion transistors, versus 956 million on the RV770, and come out at a load power of 188W versus 160W on the RV770. AMD called 256mm2 their sweet spot for the small die strategy, and Cypress missed that sweet spot.

The cost of missing the sweet spot is that by missing the size, they’re missing the price. The Cypress cards are $379 and $259, compared to $299 and $199 that the original small die strategy dictated. This has resulted in a hole in the Evergreen family, which is why we’re going to see one more member than usual.

As Cypress is the base chip, there are 4 designs and 3 different chips that will be derived from it. Above Cypress is Hemlock, which will be the requisite X2 part using a pair of Cypress cores. Hemlock is going to be interesting to watch not just for its performance, but because by missing their sweet spot, AMD is running a bit hot. A literal pair of 5870s is 376W, which is well over the 300W limit of a 6-pin + 8-pin power configuration. AMD saves some power in a single card (which is how they got the 4870 under the limit) but it likely won’t be enough. We’ll be keeping an eye on this matter to see what AMD ends up doing to get Hemlock out the door at the right power load. As scheduled we should see Hemlock before the end of the year, although given the supply problems for Cypress that we mentioned earlier, it’s going to be close.

The “new” member of the Evergreen family is Juniper, a part born out of the fact that Cypress was too big. Juniper is the part that’s going to let AMD compete in the <$200 category that the 4850 was launched in. It’s going to be a cut-down version of Cypress, and we know from AMD’s simulation testing that it’s going to be a 14 SIMD part. We would wager that it’s going to lose some ROPs too. As AMD does not believe they’re particularly bandwidth limited at this time with GDDR5, we wouldn’t be surprised to see a smaller bus too (perhaps 192bit?). Juniper based cards are expected in the November timeframe.

 

Finally at the bottom we have Redwood and Cedar, the Evergreen family’s compliments to RV710 and RV730. These will be the low-end parts derived from Cypress, and will launch in Q1 of 2010. All told, AMD will be launching 4 chips in less than 6 months, giving them a top-to-bottom range of DX11 parts. The launch of 4 chips in such a short time frame is something their engineering staff is very proud of.

    No, it's the fact you tell LIES, and always in ati's favor, and you got caught, over and over again.
    That is WHAT HAS HAPPENED.
    Now you catch hold of your senses for a moment, and supposedly all the crap you spewed is "ok".
  • SiliconDoc - Friday, September 25, 2009 - link

    Once again, all that matters to YOU, is YOUR games for PC, and ONLY top sellers, and only YOUR OPINION on PhysX.
    However, after you claimed only 2 games, you went on to bloviate about Havok.
    Now you've avoided entirely that issue. Am I to assume, as you have apparently WISHED and thrown about, that HAVOK does not function on NVidia cards? NO QUITE THE CONTRARY !
    --
    What is REAL, is that NVidia runs Havok AND PhysX just fine, and not only that but ATI DOES NOT.
    Now, instead of supporting BOTH, you have singled out your object of HATRED, and spewed your infantile rants, your put downs, your empty comparisons (mere statements), then DEMAND that I show PhysX is worthwhile, with "golden sellers". LOL
    It has been 1.5 years or so since Aegia acquisition, and of course, game developers turning anything out in just 6 short months are considered miracle workers.
    The real problem oif course for you is ATI does not support PhysX, and when a rouge coder made it happen, NVidia supported him, while ATI came in and crushed the poor fella.
    So much for "competition", once again.
    Now, I'd demand you show where HAVOK is worthwhile, EXCEPT I'm not the type of person that slams and reams and screams against " a percieved enemy company" just because "my favorite" isn't capable, and in that sense, my favorite IS CAPABLE.
    Now, PhysX is awesome, it's great, it's the best there is, and that may or may not change, but as for now, NO OTHER demonstrations (you tube and otherwise) can match it.
    That's just a sad fact for you, and with so many maintaining your biased and arrogant demand for anything else, we may have another case of VHS instead of BETA, which of course, you would heartily celebrate, no matter how long it takes to get there.
    LOL
    Yes, it is funny. It's just hilarious. A few months ago before Mirror's Edge and Anand falling in love with PhysX in it, admittedly, in the article he posted, we had the big screamers whining ZERO.
    Well, now a few months later you are whining TWO.
    Get ready to whine higher. Yes, you have read about the uptick in support ? LOL
    You people are really something.
    Oh, I know, CUDA is a big fat zero according to you, too.
    (please pass along your thoughts to higher education universities here in the USA, and the federal government national lab research facilites. Thanks)

    Yes, another excuse monger. So you basically admit the text is biased, and claim all readers should see the charts and go by those. LOL
    So when the text is biased, as you admit, how is it that the rest, the very core of the review is not ? You won't explain that either.
    Furthermore, the assumption that competition leads to something better in technology for videocards quicker, fails the basic test that in terms of technology, there is a limit to how fast it proceeds forward, since scientific breakthroughs must come, and often don't come, for instance, new energy technologies, still struggling after decades to make a breakthrough, with endless billions spent, and not much to show for it.
    Same here with videocards, there is a LIMIT to the advancement speed, and competition won't be able to exceed that limit.
    Furthermore, I NEVER said prices won't be driven down by competition, and you falsely asserted that notion to me.
    I DID however say, ATI ALSO IS KNOWN FOR OVERPRICING. (or rather unknown by the red fans, huh, even said by omission to have NOT COMMITTED that "huge sin", that you all blame only Nvidia for doing.)
    So you're just WRONG once again.
    Begging the other guy to "not argue" then mischaracterizing a conclusion from just one of my statements, ignoring the points made that prove your buddy wrong period, and getting the body of your idea concerning COMPETITION incorrect due to technological and scientific constraints you fail to include, is no way to "argue" at all.
    I sure wish there was someone who could take on my points, but so far none of you can. Every time you try, more errors in your thinking are easily exposed.
    A MONOPOLY, in let's take for instance, the old OIL BARRONS, was not stagnant, and included major advances in search and extraction, as Standard Oil history clearly testifies to.
    Once again, the "pat" cleche' is good for some things ( for instance competing drug stores, for example ), or other such things that don't involve inaccesible technology that has not been INVENTED yet.
    The fact that your simpleton attitude failed to note such anomolies, is clearly evidence that once again, thinking "is not reuired" for people like you.
    Once again, the rebuttal has failed.

    This is just sad, and I'm no fanboy. I really wanted a 5870, but only with 100% more speed than a GTX285 - not a lousy 33%. Definitely not worth me upgrading, so I guess ATI saved me some money. I'm certain that my 3 GTX280's in Tri-SLI will destroy 2 5870's in CF - although with slightly less compatability (an important advantage for ATI, but not nearly enough).
  • Moricon - Thursday, September 24, 2009 - link

    I have been a regular at Tomshardware for a while now, nad keep coming back to Anandtech time and again to read reviews I have already read on other sites, and this one is by far the best I have read so far, (guru3d, toms, firing squad, and many others)

    The 5870 looks awesome, but from an upgrade point of view, I guess my system will not really benefit from moving on from E7200 @3.8ghz 4gb 1066, HD4870 @850mhz 4400mhz on 1680x1050.

    Such a shame that i dont have a larger monitor at the moment or I would have jumped immediately.

    Looks like the path is q9550 and 5870 and 1920x1200 monitor or larger to make sense, then might as well go i7, i5, where do you stop..

    Well done ATI, well done! But if history follows the Nvidia 3xx chip will be mindblowing compared!
  • djc208 - Thursday, September 24, 2009 - link

    I was most surprised at how far behind the now 2-generation old 3870 is now (at least on these high-end games). Guess my next upgrade (after a SSD) should be a 5850 once the frenzy dies away.
  • JonnyDough - Thursday, September 24, 2009 - link

    They could probably use a 1.5 GB card. :(
  • mapesdhs - Wednesday, September 23, 2009 - link


    Ryan, any chance you could run Viewperf or other pro-app benchmarks
    please? Some professionals use consumer hardware as a cheap way of
    obtaining reasonable performance in apps like Maya, 3DS Max, ProE,
    etc., so it would most interesting to know how the 5870 behaves when
    running such tests, how it compares to Quadro and FireGL cards.
    Pro-series boards normally have better performance for ops such as
    antialiases lines via different drivers and/or different internal
    firmware optimisations. Someday I figure perhaps a consumer card will
    be able to match a pro card purely by accident.

    Ian.

    Sorry if this has already been asked but does the 5870 support audio over Display Port? I am holding out for a card that does such a thing. I know it does it for HDMI but also want it to do it for Display Port.
  • VooDooAddict - Wednesday, September 23, 2009 - link

    Been waiting for a single gaming class card that can power more then 2 displays for quite some time. (The more then 2 monitors not necessarily for gaming.)

    The fact that this performs a noticeable bit better then my existing 4870 512MB is a bonus.
