Official HD4870X2 (R700) Review Thread

[Buck47]

What would be better ATI HD 4870X2 or GTX260 SLI ???
Thanx!

Perkam answered that one:

PCGH did a MS test and found that MS only occurs when the average FPS drops below 40FPS, which doesn't happen even at 2560 resolution with 4xAA 16xAF in most games.

Crysis is the only game where drivers are lacking at the moment. Beyond that, there is little comparison between GTX 280. The X2 is faster than GTX 280 SLI in games at high resolutions and high AA.

I was reading some reviews to verify that statement and it looks like it happens in SOME games.

[Unbornchild]

Baffling?
You buy one card, or the other. If one performs better than the other in all games, it's easy choice. If it also in most -or many- games performs the same or better than TWO of the other in SLI but costs half (1 card vs 2) the choice is even easier.

It's a bug called impartiality. I can't get it off of me

Has anyone seen any review sites post up info about PCI-E 1.1 possibly bottlenecking the 4870 x2? I've seen reports comparing Crossfire/SLI on P45/X38/X48 platforms but nothing comparing the different platforms with one 4870 x2.

[emuexport]

With vsync always on absolutely no MS here, (my second ati card after the 850 xt, had voodoo1, voodoo2, voodoo3, matrox millenium, geforce 3, geforce 5900, GTX 8800) all on air idle fanspeed 1200 , idle temp gpu1 50, gpu2 70, in action temp is 65 and 86 and fanspeed between 2000 and 2800, tower is silverstone tj-07, MB is Asus P5WDG2 WS Pro, C2D @ 3200, 4 GB RAM, Vista x64, XP and XP x64.

Shakti,

Looks like your GPU2 is sticking in 3D mode clocks, check the clocks. I think its a driver issue. I get the same after a restart etc and one GPU is @750 clock and the other is at 507. By running a 3D app it resets it on mine and all is back to normal.

Might not be but just thought I'd point it out. if anyone knows of a more permanent fix let me know. (I was using official 8.8s now on 8.8betas but havent checked again)

The same here, but to see the primary gpu @ 750 I have to look at the first page in Gpu-z. CCC and the second page of Gpu-z (the one with the sensors) both report 500, as if the gpu was in 2d mode as the secondary one. But only the latter is actually in 2d mode.

I have the same problem at boot up. the easiest way to fix it and make both gpus run at 500 is to run a 3d app and then exit it.

[Shakti]

Yes, one @ 507 and the other @ 750 came with the new 8.8 driver, the driver on cd (by the way, a selfburned cd, lol) was beta and did not show this behavior. So i hope with the next release this will be corrected. I have 86 degrees on gpu2 idle with this driver...

[Cooperdale]

It also happens with another beta, 8.854. These are very good drivers, rumored to be the base for Catalyst 8.9, but still have this problem.

Today we are testing at a range of CPU’s with the new Radeon HD 4870 X2 graphics card, to try and determine what kind of processing power is required to push this new dual-GPU monster to the limit. In total there are 40 CPU configurations tested, including processors from the Intel Core 2 Quad and Core 2 Duo series, along with a number of AMD Phenom X4 and Athlon64 X2 processors…

[zlojack]

Interesting review, for sure.

I've got some issues with the conclusions, but overall, good information to have.

I love the test idea but it's ridiculous they didn't test at 2560*1600. Hey they have the most powerful graphics card atm, which gets so much fps it doesn't matter if you get 100 or 200 fps at 1920*1200. Why no love for 2560

Because not even all reviewers have 30" monitors at their disposal.

Sometimes they are ahead, sometimes they are not.The race is long.

very confusing reading all these different reviews and everyone's got something different to say lol

[Shalamay]

Hello all, I have a quick and dumb question for you as I know just about nothing about ATI stuff. I just installed my 4870x2 on vista 64 with cat 8.9. Do I need to do anything to make it work in crossfire (I don't even know how to check to see if its in crossfire)? I scored 18,652 on 3dmark06 with a E8500 at 3.8, does that seem ok. Sorry for the noob questions and thank you for any help.
