doesn't seem to be doing well

is Bittech's review going to have comparison between 8800GTX?

4 of these would be awesome!
Though I am not sure if any motherboards would have space

but im still waiting for a single GPU best card to upgrade to
(conditions: at least 1.6x the performance of 8800GTX, only require me to put in £200 after selling my 8800GTX)

this is a glue together with slower ram. Sorry to say but the 9800GX2 will probably be faster.

Not sure you can call 2 gpu's on one pcb a "glue together", but it is still a crossfire solution. The reviews so far are interesting, however the drivers used seem to vary, so will look forward to seeing bit-tech's review. The internal crossfire bridge appears to be a lot more efficient than 2 separate HD3870's though.

depends... the pictures floating around on the web show a dualpcb card as the 9800gx2, which would very likely mean lowered clocks due to heat.

I love competition in the marketplace. Its nice to see AMD/ATI jumping back into the high end game.

Now if AMD would get their ass in gear and start releasing top notch processors again to bring us back to the athlon 64 days.

could we get some Sli tests in there too? If possible Ultras in SLI, its rare to see a test have that setup so would be interesting to see results.

nice, good to see a comparison against the complete current lineup of both, but you could add something experimental, trying to crossfire a 3870x2 with a 3870 for trfire... for quadfire (i.e. 2x 3870x2) you prolly still got an nda.

I've tried both of those, but they don't work with the current drivers...

Anyway, review is live: http://www.bit-tech.net/hardware/2008/01/29/amd_ati_radeon_hd_3870_x2/1

so from looking at your benches its the same game again as with 2900xt, 38x0. in some games at some resolutions its very fast while in other scenarios its rubbish and they need to get their drivers fixed.

amd really needs an all new gpu architecture where they wont have to fix the drivers to make their products work properly with each game.

anyway, i'm seriously considering to buy one still... but i'll prolly just get a 3870 in 2 days (woot payday soon) and then give 3870x2 a month for the drivers to come out in trifire flavour and for fullcover wc blocks to be avalaible.

And just when the AMD team fixed all the driver issues and the HD3870x2 card finaly beats the 8800. Nvidia Releases the 'nextgen' that probably devastates everything in his path...

ATI Radeon HD 3870 X2 512MB. wtf?!?!?!?!

Aluminium is lighter than copper (thus helping to keep the weight of the card down) and it also dissipates heat better than copper. Meanwhile copper is a better conductor of heat, thanks to its higher specific heat capacity, which basically means that it can ‘hold’ more heat than aluminium

what? aluminum does not dissipate heat better than copper. does it?

maybe... but only if the two 8800 gt's on a single card dont end up as a failure.. which is still unknown. and if they would have something ready for an immediate counter they would have announced it by now to prevent 3870x2 sales from happening.

whilst it isnt outstanding...its a nice feeling to see AMD competing at the top again...so they arent in bed with all the developers like nvidia is, but then thats always been the case, maybe something from the orange box in the review (as they say its best experienced on ATI) would show what a game supported by ATI might do against nvidia's solutions. Just a thought

peace

Aluminium gets rid of heat quicker than copper (i.e. dissipate, radiate, etc), while copper holds onto heat much longer (i.e. better conductor, higher specific heat capacity)

supposed to read 5th february.

just checked ek weshop, there it says 31.01.2008, so 5th feb makes sense. there will apparantly be three versions, copper with acetal top, copper with acrylic top and nickel plated copper with acrylic top.

I think its supposed to be the 5th of Feb tbh.

"05/02/08" oh lol, silly brits and their different way of writing dates. I'm used to MM/DD/YY instead of DD/MM/YY

I CAN’T understand how does ATI want to come back to the top without driver improvements?? They should plan it better before launching their products… Obviously, a Ferrari will not win a race while is driven by a beginner. ;)

Good Luck to ATI/AMD! ;)
