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

By

Unreal Tournament, Mass Effect, And GRID

Unreal Tournament III

The Radeon HD 4870 X2 cuts through Unreal Tournament 3 with ease. It establishes a marked advantage in this title; 76% over the Radeon HD 4870 (excluding 1920x1200 again) and 35% over the GeForce GTX 280. Here again the 3870 X2 doesn’t shine through all that much, kind of like the 9800 GX2 and its less-than-adequate 512 MB of memory.

Mass Effect

Still based on the Unreal Engine 3, but modified slightly by Bioware, Mass Effect displays results largely mirror those of Unreal Tournament 3. Here also, the Radeon HD 4870 and 3870 X2 take sizable performance hits once the anti-aliasing is activated, ensuring that the 4870 X2 stays ahead of the pack. The GeForce GTX 280 puts up a fight at 1920x1200, but the gap increases to 30% at 2560x1600 with anti-aliasing and anisotropic filtering turned on.

Race Driver GRID

Already, the Radeon HD 4870 has impressed us. It’s thus without surprise that we find the 4870 X2 largely ahead, even if we must say that the GeForce 9800 GX2 has greatly improved as well with regards to its previous drivers (the scores doubled). Clearly, it’s at 2560x1600 that the 4870 X2 takes off (once the anti-aliasing is turned on). Its advantage over the competition climbs to 93% versus AMD’s 4870 and 99% against the GeForce GTX 280.

    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.

    looks like i need a new mobo and a bigger case to fit this beast

  • Whoa, what happened to the heat and power consumption level charts? Where they that far off the scale you dare not show them? The card performs nicely but this is ATI/AMD we are talking about, they love heat and power. So what are they?

    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

    I can smell incoming price drops...

  • 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.

Although I think it should say "doubled", not "quadrupled", since the HD4870X2 has 2x1GB.

    Point 1:
    It's great that Ati is putting up a fight and it's obvious that with all fan-boys and trash talking/flaming aside the only reason why this rapid progression on a pure processing and on the overall technological level is made possible through competition between the titans of the graphics processing world.
    .............................

    BUT!

    According to other valued/trustworthy sources the 4870 X2 manages only a 1.09 over 1.00 increase in performance.

    see link:
    http://tweakers.net/reviews/957/4/his-radeon-hd-4870-x2-versus-asus-geforce-gtx-280-pagina-4.html (Copy paste the link if needed)
    .............................

    As for the significant increase stated in this article, it's great, but only applicable to those games with integrated support for crossfire technology. (Further and extensive testing would be desirable, and posting actual facts to support claims would also be duly noted. // I know some testing has been done, but a full review on exactly what value is added with the new card, still remains to be seen.)

    .............................
    Point 2:
    As for NVidia's reply to the 4870 X2 dual-gpu card is the introduction of the 65 nm -> 55nm gpu chipsize reduction.

    Link:
    http://tweakers.net/nieuws/55050/introductie-55nm-versie-geforce-gtx-280-eind-augustus.html

    According to the news this is to take place at the end of August. meaning that the reply is ready and launched by the end of THIS month.
    .............................

    I would like to at this point state I'm not a fan boy for either side, and I myself have switched from Nvidia to Ati back to Nvidia and will keep doing this as either side dominates the market with high quality merchandise and depending on which one is the market leader at the points where I update my machines.

    My apologies to those of you who cannot read or understand Dutch.

    Here is a substitute link for the interested English parties:

    The reason I responded with such diligence and ferocity is not because I hate Tomshardware, think that Ati is doing a bad job or that NVidia rocks beyond compare... The reason for my reply is that I wish for the consumer to be fully informed and not end up buying a more expensive product for less bang/buck than originally expected.

    Stay informed folks ! (For those of you who have a no limit budget the 4870 X2 might be the way to go, other than that, if you are looking for a more financially affordable card, wait for the 55nm NVidia GTX280 revision (name is yet to be determined, release expected at the end of the month))

    That concludes my rant for the day and I hope you guys are now fully informed or that I have at least have sparked your interest on the field of gathering information before drawing a conclusion based on a single review ;)

    Look around! and stay informed ! Ati and Nvidia both rock and the best of luck to both companies... may the struggle be eternal and the progress fiery and extreme!
