How good is a 640M in a laptop?

I find it hard to research how decent it is in a laptop and what kind of graphics it will be able to achieve.

Does it directly compare to a desktop 640?

Thanks for that link...very helpful. I like at the end how it shows the FPS for the different games...just wish it said was resolution that was for...or at least, i couldn't find that.

A important specification issue is the 640m comes with both ddr3 and gddr5. You have to really dig in to a particular laptop to often find what it has. The harder to find , it probably has the slower version. Which is ddr3.

It's meh. Better than the best current integrated solutions but not by a whole lot. You'll be able to play games at 720p medium detail settings and get smooth frame rates nearly all the time.

My friend has a laptop with one coming in a day or two, so I'll find out soon. They seem fairly capable. Definitely more than anybody needs to derp around the internet, and I think they'll run quite a few games on medium settings, with only the intense ones dragging it to the unplayable range.

Agreed. I had one that played a LOT of games fine on native res at 1080p. Obvously AA was a no-no but Mass Effect 3 for example ran like butter 40-60 fps.

It's WAY better than integrated...problem is this section of AT views anything that isn't cutting, bleeding edge as a step above crap.

I did not say that:) Especially on a tablet screen. What resolution will that run?

You can look at reviews of gt 640 desktop cards which also use ddr3, but run at 900mhz, while mobile gt640m runs at 625mhz. In a small chassis like that, it might run slower? I don't know.

Buying anything below the 650m is tough there's probably 40nm/28nm versions along with gddr5 and ddr3 versions and they can have several different specs for # or cores.
