nvidia GT 650m vs GTX 670m

Agreed, you can safely ignore niss... he focuses way too much on stuff that really doesn't matter.

The 670m is a valid purchase as long as you understand its a rebrand and get it at a good price.

One thing no one has mentioned... most laptops shipping with the 670m are designed for enthusiasts and have a replaceable GPU.
(The 670m is consdered entry-level into the highest rung of enthusiast mobile GPUs.)

Laptops shipping with 650m/660m or lower do not usually have that option as they are usually "thin and light" or "value" laptops.

 

I know, from research it should take at least 50w but if fully stressed with cpu and gpu it should take 70w more then the 650m machine.

670m I believe is a 75w card and tests have been done to show that the 680m consumes 12w less then the 670m and the 680m is what a 100w card. So in reality the 670m is more lie a 110w card if tdp was power consumption but its not but just as an example 110w compared with a kepler tdp and 650m is what 35-40w.

Theres a reason why 680m easily oc past 8000 3dmark11 as they are releasing very slow cards in order to make way for a complete 28nm refresh with the 700m series. Imagine those 670m owners thinking wow 770m performs twice as fast and takes electricity at an affordable price etc.


Another thing is the 680m and 675m are both 100w tdp cards but there is a 70w+ difference power consumption wise between them.

 

TDP will be near the upper bound for heat output, not the lower bound. if the 670m is a 110w card then Nvidia just screwed all the OEMs that designed their systems to cool 75w.

BS. Two review of the Clevo P170EM, one with the 675m, and one with the 680m. Difference in power consumption? 35w.

Like how the difference between the 680m and 675m was 70w+?

Hm, I probably should have taken the other posters' advice.

 

Based off this if I ran my 675M balls to the wall 24 hours a day for a year it would cost me 82 dollars more for that 35W.

In other words, it would take me over two years to make up the $300 difference between a 675M and 680M. Again.. I would have to put it under load 24 hours a day.. for a year.. I would basically have to go into Eric Cartman mode and have my wife feed me and give me a bedpan to see any chance of saving money.

Edit: sorry I used a number that was 3 cents too high per kwH. Its actually $73 per year more for the 675M at 35w more during load.

 

Um... I'm too lazy to delete Nissangtr's (R.I.P. - permabanned) posts.

Y'all don't mind if I leave them up for posterity's sake, do you?

On the plus side, by leaving them up, we can always look back at them and compare to see if any new poster is nissangtr in disguise.




Breath easy my friends.

 

well im glad this madness has come to an end, in other news, my gtx 485m uses less power than a gtx 670m...

 

For everyone else that might consider (or not) an "old" 670M purchase (where I am they are just about the same with 660M), on stock voltage it will do about 4000 points in 3Dmark 11 without any heat problems on a good cooling system. And the GPU is +3500 points. This is about what a 675M can do stock. And if this 670M is just a 570M (almost), that is quite amazing and I guess is what Nvidia does - one good card from the start with limited performance that can be renamed in time with some extra grunt.

 

P.S. just keep an eye out for username Hondahsv
