2600 65 mn

how the 65 mn process affect this video cards less heat issues?

 

more power efficient and less heat, basically allowing for higher clocks.

 

are nividia dx1o cards 65mn

 

Just 80nm atm.

Mike.

 

this transfer to more room for overcloking?

 

Yes, but I would highly recommend against it. If you want to overclock, I encourage you to get a desktop.

 

I haven't seen TDP's for the mobile cards yet, but in on the desktop versions the R600 series GPU's are running hotter than the G80's. I wouldn't expect a lot of overclocking room with stock cooling.

Of course trying to make a desktop to laptop comparison is pretty meaningless so my point may be moot

 

ATI's midrange and lower parts are MUCH cooler and power efficient, and will hopefully be good performers, cause in the end, the value cards and IGP's are the biggest sellers, and where most of the money is made.

 

Yes, while the high end ATI desktop card is really hot, it is not 65nm so the mid-range cards should run cooler. However they are still new, and with the 8M series being new I'll be making sure I do my research before selecting one. The 8M supports DX10 and has some cool power saving features I'm hoping will help a lot with gaming and battery life.

 

The smaller the chip the less heat it outputs and the less voltage is requires.

 

I dun care, i ll take any that has more power, in this early stage, the ATI..

 

65nm doesn't mean anything by itself.
It means the chip gets physically smaller, and that is it.

Often, this can be leveraged to a) improve performance/overclocking headroom, or b) lower power consumption, but there is no general rule that this will always be the case. It might perform the same as a 80 or 90nm part, or it might run hotter or it might run cooler. So the only sensible thing to do as a consumer is to ignore the process size used to manufacture the GPU, and just look at the end result. How does it perform, how hot does it get? And then screw whether it's made on 65nm or 200um or with vacuum tubes, because that in itself doesn't mean anything...

 

ATI x2600 and lower are on a 65nm process and the TDPs for them are very good, a stupid amount lower than the 80nm HD2900XT, which could keep going past 1.3ghz but even cooled with liquid nitrogen it gets too hot at that point ^^ WAY too much leakage.
