i wonder why wanna compare 3870x2 with gtx.. from the name itself shows that radeon 3 series is suppose to fight with the to-be-released nvidia card or at least the new G92... not the one that had been released last year!

if people comparing the coming radeon with nvidia 11 months old card, then it shows how slow ATi is..

summore there's no point for ATi to produce a card just to fight with gtx or ultra since nvidia has makes lots of profits from those 2 card already..

the new released 3870 currently looks disappointing and seems imcapable to fight with either gtx or ultra..

i think ATi is using wrong strategy by naming it with 3 series.. suppose they just put name like 2970 to avoid high expectation from end user.. doh.gif

note my keypoint.. currently..

i think the keyfactor here is the driver.. if it is true the dissappointing performance now is bcoz of driver, then ATi can only win if they manage to come out with a good driver before the new nvidia card comes out.. if not, then they are just going to repeat the same mistake like before...

not we want to compare with 11 month old card...but temporary 8800ultra is the king...if we are not compare to it..then which to compare?? blush.gif cos 2 core in 1 card the price almost equal to 88gtx price (assume we buy 2 HD3870 price) unless we doin sli for 8800gt blush.gif

people are comparing the featureset vs pricepoint vs performance..

The name hardly means anything. It's an arbitrary name chosen by marketing. I think they just wanted to distance themselves from the failure that was the R600.

And they were never planning to go up against the gtx or the ultra with a single RV670. It's strictly a performance midrange card. The fact that it can even be compared against a G92 is a bonus. And i doubt it's the drivers. This thing is a direct derivative of the R600. It just seems that the 6xx series tends to perform less than the paper specs would have you believe. But RV670 is a fine chip really for its price range.

i like to compare with 8800gt more than 8800gtx.. both in the same price range, and both are new card.. and for now definitely 3870 lose.. 3870x2 shud beat 8800gt, since it has 2 cores.. and higher price.. but will the the 20-30% improvement enuff to beat the next coming nvidia high end that might has same value as the 3870x2? hmm we will see..

yeah i realize this rv670 is a fine chip.. but in the eyes of mainstream, i dun see it as drastic change from 2900xt.. i'm not talking bout the technical details... just bout pure performance

noticed 3 things:

the psu looks like a silencer 750, one of the "QUAD SLi Ready" PSU.

only one cf bridge connector on the ultra 1337 dual gpu HD3870 ...... dont think there will be a 16 gpu setup, FOR NOW.

only 3 cf bridge were used for the quad cf setup ..... just weird.



i assume AMD is currently being run by some humanoid looking alien race with advanced graphic technology and absolutely NO HUMAN MARKETING SKILLS / STRATEGY at all. but thats just me.

You finally saw through? laugh.gif

irenic, not everybody needs an expensive card to e-p3n15 wagglery.

When the HD 3850 256MB reaches RM500-550 and 512MB, RM650-RM700 with non-official boards (look out for Palit/Xpertvision), nVidia can't beat them in any way. Even the 8800GT 256 non-official is still 200USD.

Crossfire 2 3850 512MB/3870, and you get a system that can beat the new 8800GTS in Crossfire by a lot. Don't underestimate AMD, they're still in the game and by the looks of it seemingly winning this winter in sales.

yeah i agree with u.. but remember that dual gfx wont have the performance of 2 cards.. especially crossfire where u can only feel the benefits in certain games.. while some games will result in poorer performance when cf enable..

well i dunno how's the performance of 8800gts g92 yet, but if 3850 cf can beats the card in all games or benchies, than that's very good.. if not, better stick with single gts.. less heat.. less hassle..

I won't say all, but keep in mind that the 8800GTS "New" is still bandwidth limited. Performance will whimper when you go to 1920*1200++. Dual crossfire cards are the way to go in high res.

It's probably caused by the memory management bug on the G92 based cards. There should be some nice boosts when they fix that.

256-bit is 256-bit. You can't bypass that unless you get GDDR4, or you do multi-GPU.


The GT doesn't have any problems with resolution scalings. They seem pretty fine besides for Crysis.

I know the bug specifically affects Crysis, but generally memory management bugs like that are generic, so it probably affects more than one game. Even previous generation cards that used gddr3 on 256bits don't show such irregularity, unless it's a bug. How does multi-GPU help? You are not changing any bottlenecks, even with perfect 100% scaling.

evryone would love to get good graphics, but good graphics come at a high price. 2 graphic cars are a nono for me, unless i have the money.

some of the current cards also needs to be on par with newer technology, and thus, if we using old stuff, hv to change to new 1 also.

3850 OC is a good card..
