Test Drive Unlimited And Crysis

AMD's Radeon HD 4870 X2: R700 First-Look
By

Test Drive Unlimited

With Test Drive Unlimited, the superiority of the Radeon HD 4870 X2 is less pronounced due to the lack of a CrossFireX profile. As a result, the card behaves like a 1 GB Radeon HD 4870 here, with its advantage over the 512 MB Radeon HD 4870 not exceeding 11%. This is enough, however, to place it in front of the GeForce GTX 280, but only when the anti-aliasing is activated.

Crysis

The Radeon HD 4870 X2 hits the target with Crysis, which has become a playable game for the first time at 2560x1600. It’s here that the presence of 2 GB of total memory (1 GB that’s actually usable, just as a reminder) has proven itself to be rewarding. The Radeon HD 4870 X2 turns out to be more than two times faster than the Radeon HD 4870 (with the exception, as always of 1920*1200). Its advantage over the GeForce GTX 280 comes in at 77% in 2560x1600, and increases even more to 118% once the anti-aliasing is activated, even if this mode remains unplayable.

The older 3870 X2, with its 512 MB of memory per graphics processor, isn’t able to outperform the Radeon HD 4870 despite its superior horsepower and the same drivers. This shows that the behavior of a bi-GPU card depends quite a bit on its design.

    Dear Sir,
    I admire your efforts to show the maximum possible both as description and tests and I would like to ask a couple of questions:
    1. Is it possible to show the same tests but with AMD configuration?
    2. Is it possible to show the same tests but with at least 8AA/16AF and soft shadows, dynamic lights, plus description of other visual options?
    In appropriate for you time I shall expect your answer.
    The reason to spend so much in time, research and money by my humble opinion is to offer the best possible and realistic images on the clients and gamers. Please, forgive my words but to have such video cards and test them only with 4AA/4AF is ... a shame. I save as much as possible and when I upgrade something I chose carefully the best I could afford.
    Thank you in advance for your co-operation.
    Yours faithfully

    Good job ATI/AMD! really good card you have here lets hope its cheaper then the GTX 280. I'm glad i waited it out now i can replace my old setup. Now i will get new X48 board and 2 of these puppys and im sure I need a better power supply I don't think a 750 watt will do it.

    It says at the end of the article their power meter went kaput, and also not to expect much in the power consumption department anyways.

    Someone explain to me what this means in english?
    "Back when we tested the Radeon HD 3870 X2, we found that the biggest impact on performance was attributable to the board’s memory capacity, since memory on a bi-GPU card has to be divided in two. And in order to assure adequate performance, you often have to multiply the quantity of memory by four, which is what AMD does with the 4870 X2." from page 1

    It's nice to see AMD/ATI challange nVidia again, it's been too long nVidias market. My take is that this situation can only benefit the consumers; push for faster GPU's to more affordable prices. It will be interesting to see nVidias run to retake the performance as well as the midrange price/performance crown.

    The HD3870X2 had only 2x512MB memory, and each GPU could only access 512MB, which held its performance back. Although I think it should say "doubled", not "quadrupled", since the HD4870X2 has 2x1GB.

    Thurin The reason I responded with such diligence and ferocity is NOT because I hate Tomshardware


    I'd like to stress that fact, as I read Tomshardware every day and have always enjoyed reading the news articles, however I would like the news to be as unbiased as possible and lately it seems Toms has been slipping a little.

    $500+ for 2 gpus with 1gb memory each? i guess its worth. I usually never spend more than $300 for a card so i guess ill still wait till the 1gb 4870 comes out. I think the 260gtx would have been worth it, if it had dx10.1...even thought i dont know what the .1 does.

    The 10.1 is just an extended graphics capability suite including all features and extras that were planned for dx10 in the first place but couldn't be included in the primary release.

    ( hence the relatively small difference between dx9 and dx10 and dx10 games being cracked to work on dx9 machines with all the same effects save for the few bits of eyecandy that make up the difference between dx9 and dx10 )

    so... nvidiot will continue to offer 2nd rate overpriced underperforming stuff that's obviously been price inflated in the first place and so... so it's easy to reduce the ripoff price in the face of genuine article? Is that about it Thurin Michael out? And you are protecting me how? By baffling bs? How stupid are you? Or do you think we are?

    Blow your doors off in really high resolution. And the drivers evolve.

    Best card. You really are out michael - they pay you for that?

    btw how's the massive recall? thx for looking after our interests - now go to the corner and soil your nvidiot undeez.

    ATI wins. There will be lots of reviews.

    Reading is an art too Zooty *winks*

    It's not a flame post towards Ati, and Ati does win, for now... at high costs.

    before the month is over, Nvidia will win again at high costs... This is the cost of progress.

    I;m not on either side, whichever is best I'll go for... I'm promoting and supporting the battle between the two industrial giants.

    Take one out of the race and progress will become lethargic, dead slow and the prices will be insane... even more insane than they are already...

    But if you choose to see me or my posts in a narrow minded way resembling the likes of what you just exhibited, then by all means go right ahead. You are entitled to your opinion.

    However you may want to try and keep it a bit more decent.

    (side note: using some mutated version of hackz0r 1337-speak or whatever this bit of slang is will not improve your standing with me or anyone else I wager... Try keeping it clean and I have no problems discussing any of the matters at hand with you.)
