The Card

Obviously, this is a large card. But like the 3870 X2, AMD has managed to keep the board fairly compact for having two GPUs and 1GB of GDDR5 on board.

The R700 does have a plate across the back of the card like the 3870 X2, and it also has RAM on the back as well (the 4870 carries all it's RAM up front). These RAM chips are different than what is used on the single 4870, but capacity and performance should be identical.


The R700 needs one 6-pin PCIe power connector and one 8-pin connector

The layout is very clean for the amount of stuff that needs to happen here.


That's a black AMD PCB

    I have seen 4 so far plus all the individuals that have personal cards now and they have ALL been 2gb models. like I said earlier ATI doesnt even have a 4870 X2 1gb model in their slides. Reply

    I've become curious as this is like the 4-5th comment I've come across that talks about a 2GB model and a 1GB model. What I'm curious is whether or not you are talking about a 2x2GB model, to make 4GB across 2 cards, or just 2GB in total RAM, because the one on this site has 2GB of RAM total 2x1GB, 4GB across 2 cards.

    I have a feeling many are just getting confused, but I'd like to sk to make sure.

    AMD, you fail! Without even reading the whole article, which I will finish in a sec, that board layout already has me in a tizzy. Are you really going to point the PCI-E 8 and 6 pint connectors facing that way? Maybe because it's so long, but I am not sure I like that idea of having a stiff cable (most PS's these days have sleeved cables) having to be routed that way. Then again, I am flying off half-cocked right now, so (if you live around Austin, TX and listen to 93.7 12 to 1, you'll know I am part of Snatch... so this may just all backfire in my face after I get done reading the article).

    Yeah, I have to agree that is a stupid way to point the connectors..... DOWN? They should be pointed towards the wall of the computer, not the bottom of the computer, in order to take into account that most people have a card or three UNDERNEATH those video cards. Reply

    I didnt read through the whole article but why did Anandtech end up with a 1024mb version when EVERYBODY else is getting 2048mb versions? heck even all the ATI slides showed 2048mb for the R700.

    I was wondering the exact same thing.

    Maybe they are going to release even better results with the 2GB version and blow away Nvida!?

    I am a Nvidia Fan Boy - or should I say - who ever gots the biggest guns Fan Boy, so if ATI brings in the meat and potatos, Ill eat em all up.

    PS: I have an ASUS X38 DDR3 with QX9650 & 2 Gigs DDR3 1600 7-7-7-20, and I have been running just 1 EVGA 8800 Ultra Because SLI is not supported with this mobo, so when I upgraded from the 680i I sold my other Ultra...

    But!!!!!!!! This MOBO HAS CrossFIRE!!!

    As almost all other X38/X48 Mobos do! And I have been waiting for a Cross Fire solution that was worthy. If I could just get 2 of the 4870x2 cards in my system for Quad GPU - that would be really nice - give my Dorkfielf 4.0 something to do. LOL

    PS; Also need to upgrade to Vista 64 as a 32 bit OS would not like 4 gigabytes of ram on the video cards, and with 2GBs system memory - may be a problem - plus upgrade ro 4 GBs of course...

    Hm, reply on your PS: try to install service pack 1 for Vista... my 4 gigs are there... before it was only 3.3 gigs... i have read somewhere that the new core in SP1 supports higher ram amounts... Reply

    Ram on video card means Jack Squat in all but a few games out, even then its not noticeable. A 512meg vs 2gig card means no performance difference if 2 equal cards.

    It doesn't? That's funny: every single testing place I have seen says that when you have a lot of memory on the card to hold textures and other things, it does help with performance a lot, since they don't have to page things to the hard drive or pull things from the hard drive as often. Reply

    That's if, AND ONLY IF, all the stuff doesn't already fit onto the cards memory. Most of the time you'll run the FPS into the ground before that happens, negating any performance gain you may possibly get. If, however, you happen to find a game where the FPS remains high, like in GRID, then it will help. Course, you'd need quite a big monitor to get a resolution that high, but that's beside the point.
