How scaled down are notebook gpus?

Compared to their desktop counterparts? Where would an 8600 gt or gs stand? Like maybe in the 7000 series?

 

what do u mean? do u think the 8600gt is a 7000series technology or are u asking them to be compared to desktop 7000 cards?

first situation, theyre 8 series, second situation, theyre probably around the 7600gs or gt area.

the go7600 for example was said to be based on the 7300GT or GS

 

just look at benchmarks

 

Its difficult to get benchmarks that are accurate, because of the differences in other components, which have an affect on overall score. Comparing a mobile card with a desktop one, is not easy. However, the 8600M GT is said to perform slightly slower than a Go 7900 GS, and that is similar to a desktop 7600 GT, possibly faster.

You also have to take into account how time progresses. More advanced and better optimised drivers for the 8600M GT will be released, and since most newer games will now use DX10, a bit of performance can be gained there.

 

Generally speaking, the difference isn't that big. Generally, I'd say you lose maybe 30-50% by going from desktop to mobile GPU. And that's while the power consumption goes down to maybe a tenth. So yeah, you lose some performance, but considering the improvements they need to make on power consumption, you actually get off lightly performance-wise...

 

That's a pretty big difference dude =\

 

hehe yeah, thats also fairly accurate from what I have seen in benchmarks.

Granted what he said is very true about the power used and size.

Your getting way more than a 50% shrink in those areas so they are doing good.

If we are lucky the 8800m will be on a 45nm process.

With a high end cpu a 8800gtx can kick out close to 13000-14000 3dmark06. Lets see how close the notebook version gets.

 

im guessing somewhere around 8~10 grand.....depending on processor, because in 3dmark06 the processor counts too ya know

and to the original poster......... notebook GPU's are about 2/3 as powerful as their desktop cousins

 

Yeah I know, thats why I made sure to include "with a high end cpu" its also the reason I plan to get a Asus C90 and toss a E6600 in there.

 

It really depends, but the difference CAN be huge! For example my desktops 7900GS 256MB performs faster than a notebooks dual 7950GTX cards in SLI with 1GB of Video RAM total. I would say though in general you get quite a bit better performance per watt in a notebook's GPU, when compared to a desktop.
