x1800 and you.

Considering an x1800 runs so hot and takes up so much power, since it is mxm, if one day you decided to up and exchange it for a 7900gs or a x1900xt, would it work BETTER?

Given that pcs made with a x1800 hafta be cooled much better then normal pcs...

With that in mind, considering all this, would a laptop with a x1800 be primed and ready for a dx10 card?

 

A Go 7900 GS might just run better, and probably cooler. However, why would you want to upgrade to that card. Its quite an expensive procedure to go through. First spend money on the Mobility X1800 then purchase a seperate Go 7900 GS, and install the card. We still aren't sure of what the specification for the new Mobility X1900 are, as ATI hasn't disclosed them. It will probably resemble the X1950 Pro desktop card with 36 shader pipelines, however. What is likely, is that it will be built on the 80nm process, and so it should be cooler, and a bit more efficient.

The Mobility X1800 isn't a DX10 card. They aren't going to hit market fro a long time yet. Until nVidia (and ATI, when they release), address power issues, it won't be viable to install a DX10 into a notebook.

 

Well, a new GPU Interface could be develouped in the next few months. At the time being, there isnt even a DirectX 10 Card out on the market yet, so for now, it proabbly is not ready for a Dx 10 GPU.

You need to bear in mind the efficiency of the Heatsink and Cooling fans, they may not be suitable for increased Heat Dissapation from a faster GPU. And also, the Power Supply Unit may not be good enough also.

 

All I'm saying is, given the power issues and the heat given out by the x1800, would it be feasible that it will probably be around the same heat and power a dx10 card would give?

Would it work, minus a few minutes of life...?

The x1800 desktop cards were one of the most power hungry, heat dispensing cards out there, so this shouldn't surprise anyone. But how do they compare to a 8800gts, or a 8600, which is probably more along the lines of what laptops will get? (DX 10 with the speed of a 7900 gtx)

 

Shouldn't be too far off.
The 8800 consumes a bit more (~10% power than a X1800 (non-mobile version), but that's probably acceptable... Probably...

It is a pretty efficient architecture. Hard to say when we'll see mobile versions of it though, or how much slower (and cooler) they'll run.
Still, I wouldn't expect the power consumption to be a problem. They'll probably try to keep it within the same thermal envelope as existing notebook gpu's.

 

The Mobility X1800 isn't massively hot. ATI wanted to keep within the boundaries of 30 to 35 Watts for its TDP, and the X1800 is around that. Now, consider the Go 7950 GTX. It has a TDP of about 45 watts, I believe. It gives out alot more heat. Most Go 7950 GTX have better cooling systems though. But, syaing the Mobility X1800 is as hot as some of the DX10 cards isn't correct. There are cards that are hotter, but only a few. DX10 cards, byt the look sof it, are probably going to be about the same.

At the moment it looks like they will never get to the level of "cool" we have now, considering what they are like on the desktop level, but nVidia and ATI will be more than willing to cut back on the speed substantially, to get these cards into notebooks. They will have to assess what these cards are going to do. The higher end cards DX10 cards will most likely suffer a slight increase of their peak heat output. Mid range cards, however have to stay the same. Cramming a DX10 with more power than a Go 7700 into a 14.1" notebook is going to be difficult. For that reason, nVidia and ATI will have to work very hard to reduce heat output.

 

It's not always the component that causes the notebook to get hot. You happen to have a Uniwill notebook (don't remember the model #)(also rebranded as the Alienware Area-51 m5750), and it gets hot. I tested the Alienware m5550, which is essentially a smaller 15.4" version of the m5750, and it had a rather poor cooling system. Looks like the same goes for the m5750. So, in this case, it is the notebook more than anything that contributes to the significant heat output.

 

The m5550 does have a poor cooling system; however the m5750 has a great cooling system, and I can keep temps before 50c...

Perhaps some are good, and some aren't... I've read conflicting reports on this as well...

I've heard of some people who don't even use a cooling pad on an Alienware m5750, and it runs just fine...

I'm not sure...

The thing is, if you check temps of the desktop x1800 versus 8800 gtx, you'll find they are quite comparable... And if the notebook world gets a 8600, that'll be even better...

 

The mX1800 doesn't run hot, IF the manufacturer properly sets the fan speeds.

I'm shure it's just a simple fan speed issue. Everyone complained that their X1950XTs ran very hot. When I got mine a few days ago, so did it, but I found out that the fans were set to run at 28% until the card reached 100c then the speed changed to 100%. I just got ATI tray tools and upped the speed to 70%@40c and 100%@55c and over, and now it runs 36c idle and 42c after an hour of gaming.

But still, if this is the same problem with the mX1800 then it's the notebooks manufacturer's fault.


Anyway though, why spend a massive amount of money on an X1800 laptop just to upgrade it? When you can buy a far cheaper GFgo6600-6800 MXM laptop which will probebly be upgradable to the GFgo8800GTS, which will be released in about 10 months or less.

 

I run a FS Amilo XI1546 (the same as an Alienware m5750) without coolingpad, and it can get somewhat hot while running games, running WoW at default clocks and it can reach 70°C at the temp sensor, which seems to be located at the cpu, and this is with a 0,05 V undervoltage on the cpu... Tho in some games, it wount even reach 65°C ?! :S Tho it dosent seem to be unstable at all, and by the oc'ing ive tryed, clocking the gpu to standart speeds (underclocked from 450/500 to 400/468), it dosent seem to reach much higher temps, 2-3°

 

There is no laptop other than the amilo alienware that has the x1800

so their heat is interrelated.

Most people describe the heat as untolerable.

 

Some people can run without cooling pad, and yes, their is one other laptop...

The best Xps of them all... check for yourself.
