    CF/SLI review incoming?

    also you might want to check latest prices - the one suggested in the article @ scan isnt what they are charging today when they are on sale....

    Re: Reviews - Sapphire Radeon HD 7970 in three-screen Eyefinity

    how is the fact that it's £200 more for not that much of an improvement in performance not in the bad section ?

    really need to see the XF results for 6970s, for £50 more you could get what, 40% more performance than tha 7970 ?

    Because it's the fastest card out there. If value worked linearly then we'd all be using intergrated graphics or something - anything other than bottom end costs more than it gains you percentage wide. Add in early adopter markup and it's even more explainable. Just look at what's happening in the markets - people are actually willing to pay more than the original selling price to get one, hence prices are actually increasing.

    Waiting for BF3 drivers? Its not like when BF3 was originally launched. They have shown that the card does indeed run with last months drivers.

    Think I might personally wait for the 7890 to benefit from the new core but not the burden of the typical price. That and XFX's DD version after my XFX 6970 died after overheating playing BF3, eBuyer refunded me £240 after only 10 months >_<

    My mates taking delivery of his Sapphire 7970 shortly then I can have my 5770 back and replace my 4770 I'm currently stuck with

    Look at the benchmark results. The card is seriously under-performing on the Frostbite engine compared to all the other results.

    Annoyingly, Anand's GPU Bench 2012 does not have the CF and SLI results as the 2011 table did. Some quick maths, and looks like the 5870s in CF still outperform the 7970. Think I'll save the cash for now.

    Really?

    *Runs off to check*
    Kalniel: "Nice review Tarinder - would it be possible to get a picture of the case when the components are installed (with the side off obviously)?"
    CAT-THE-FIFTH: "The Antec 300 is a case which has an understated and clean appearance which many people like. Not everyone is into e-peen looking computers which look like a cross between the imagination of a hyperactive 10 year old and a Frog."
    TKPeters: "Off to AVForum better Deal - £20+Vat for Free Shipping @ Scan"
    for all intents it seems to be the same card minus some gays name on it and a shielded cover ? with OEM added to it - GoNz0.

    That's true. Some people from AMD have hinted it's not a driver thing though - it's the way the engine is coded - a patch would need to come from Dice.

    Grr....That's bad news I didn't want to hear
    DICE have been abysmally slow with patches - still have the risk of "BF3 has stopped responding" when in a jet, still occasionally get the "infinite loading screen" and still get the "something went wrong" issue which takes 4-8 attempts to join a server.......and that's before we talk about hackers.

    Using the 580 as a benchline in DX10 (I can't get DX11 to appear) it scored 60.3 FPS in 2011 at 1920*1200, and 41.7 in 2012. A factor of 1.446, which I can't explain....
    However, if we apply the same factor to the 75.2 FPS that the 5870CF achieved in 2011, we get an approx score of 52.0 FPS. This compares to the stated 7970 score of 50.3.

    I'm using the Iron browser, and no longer get that one. I get it every time in FF and infrequently in IE.

    Well it's true and reasonable in both cases. For Bulldozer you've got a new type of processor that doesn't behave either as a pure full cores chip or as a combination of full cores and SMT, we've got modules that work differently. The way PCs are currently designed the OS is responsible for the threading, so either you have to go back a step and stop presenting cores to the OS (and thus applications) or you have to add a bunch of transistors to the CPU that has to gather up all the OS requests and re-sort them into better ways of doing it - that's a waste of transistor budget when it's something that can be fixed in software.

    I don't know the full issue with BF3, but I know the FXAA (and associated effects) is one area where the nVidia specific code actually runs faster on GCN than the AMD code (that was designed for VLIW4/5). Again, maybe AMD *could* do some driver magic, but it's possibly too late by that stage, the calls from the game are the better place to fix it.
