kid_maximus Posted January 23, 2013 Share Posted January 23, 2013 Title says it all. i have in front of me a set of 675m's and 6990m's. which would perform better in terms of speed and reliability? don't really care about battery power since i use my laptop on ac power all the time. yes i know the 675m's are rebadged 580m's, got them as cheap as chips so thought they would be of some use in the future. i have an m18x r2! any help appreciated Quote Link to comment Share on other sites More sharing options...
Guest Posted January 23, 2013 Share Posted January 23, 2013 675M SLI will be better performance than 6990M CF. Quote Link to comment Share on other sites More sharing options...
omega939 Posted January 24, 2013 Share Posted January 24, 2013 Question though...How come ati mobile gpu's have higher wei score compared to Nvidia mobile gpu's when in fact nvidia performs much better but have a lower wei score? 1 Quote Link to comment Share on other sites More sharing options...
littleone562 Posted January 24, 2013 Share Posted January 24, 2013 Wei score probably has some polygon/geometry computation aspect to it where AMD is superior, but all in all 675M will perform better in gaming. WEI is also a flawed test. 1 Quote Link to comment Share on other sites More sharing options...
TurbodTalon Posted February 10, 2013 Share Posted February 10, 2013 I would also suggest to go with the 675M SLI. I never had a problem with my 6990M CF setup. Used and abused it. It just seems like Nvidia has a hardier card and better driver support. Quote Link to comment Share on other sites More sharing options...
Ali3nSan Posted February 20, 2013 Share Posted February 20, 2013 I also have a 6990 CF setup and would also recommend you join the green team. I have had many issues trying to setup games to not have framerate issues. Currently I can't play Aliens: Colonial Marines without the games frame rates dropping when you shoot. To save your hair go green I am going to upgrade to the Clevo 680 soon Quote Link to comment Share on other sites More sharing options...
Bl4ckw1d0w Posted March 11, 2013 Share Posted March 11, 2013 I have a 675m SLI setup and can honestly say I have no complaints haha. I have played many games and have found nothing to trip these up at all. I would guess that they may generate a little more heat then a 6990m cf setup due to the higher clockrate but nothing alarming. If you were considering overclocking I know my 675's overclock fairly well but never had the chance to play with Radeon cards but ive herd there similar to the processors meaning they overclock with ease.
