the Nvidia GT 840M is better than gt 740m . about 30 % better than GT 740M
why I see on netbookcheck website GT 840 is higher class than GT740?
luckily Asus laptops GK107 so they are better than 840M! Beware :D
found the answer! we have 2 kind of 740M based on GK107 (older and better one which your bench are based on) and GK208 which is shit! (64 bit one and slower) ...
anything with a GT in the model number from NVIDIA is a higher quality, faster card. period. if you take any GT card from the previous tire and test it against any NON GT card from the new tier. the older GT card will almost always win. this test should really be the 700 series GT vs the 800 series GT card.
Sados at Nvidia cut corners on the newer mid range GPU by crippling the card with a 64bit bus as if it was 2005 and using higher GPU frequency to mislead consumers into believing it is higher performance. I honestly don't see why they would do that to a card like this. It isn't like a 810m or 820m
ow WTF? i have 740m, but WTF?
