Basically, the specs of a desktop Radeon 5830 in a notebook GPU. Good for notebook mining, it you are into that sort of thing, as well as frying eggs, if you know what I mean... Shocked Wink Oh, and it can probably game pretty well too.

And here is the laptop:

Video Card (options):

    * 1.5GB GDDR5 NVIDIA® GeForce® GTX 460M
    * Dual 1.5GB GDDR5 NVIDIA® GeForce® GTX 460M – NVIDIA® SLI® Enabled
    * Dual 2GB GDDR5 NVIDIA® GeForce® GTX 580M – NVIDIA® SLI® Enabled
    * Dual 2GB GDDR5 AMD Radeon HD 6990M AMD CrossFireX

    * Dual 2GB GDDR5 AMD Radeon HD 6990M AMD CrossFireX


So that thing equals roughly a single desktop 6970 in rendering power (2x mobile 6990s) which is actually quite amazing for a portable system. Even a single one equals about a Radeon 5830 or 6850.

I just wonder how a laptop is going to cool two of those chips in Crossfire.

p.s. If the cooling is not a problem, that system could mine about 600mhash/s worth

Yeah, me too. Maybe they reduce the clock speeds?

My M17x has two 5870m cards and has been mining non-stop for about two weeks now.  I can't imagine the M18x, a newer and better designed laptop, would have any problem cooling the 6990s.

Might have to step up...glad I didn't pull the trigger on the 6970s!!

If it helps, laptop components maintain their value far longer than their desktop counterparts.

A year from now a desktop 6990 might be worth a quarter of what it's worth now.  The 6990m will almost be selling for the same price it sells for now.

Search eBay for Mobility 5870 or even 4870 and you'll see what I mean.

Not really. Even the 5970 desktop dual GPU has retained 95% of it's original value since it's release in 2009, 2 years ago.

Those are sold by amateurs who think they're worth a lot & can scalp buyers,
or chinese manuf. with random stockpiles, you can't even upgrade GPUs on the vast majority of laptops

On most laptops (except very high end ones) they are soldered onto the motherboard so there is no way to switch them out

Not really. Even the 5970 desktop dual GPU has retained 120% of it's original value since it's release in 2009, 2 years ago.

Fixed it for you...

The main reason the 5970 still has so much value today is due entirely to bitcoin.

The MXM 3.0 slot is slowly being adopted by laptop manufacturers and will soon be the standard for the mobile video card market.  Those "amateurs" don't think they are worth a lot.  They are worth a lot.  Mobile gpus still go by the old rule "half the power at twice the cost".
