sager2090/ifl90 8600gt..

please help, this has been stressing my notebook buying quest out alot.
im gonna quote BuckeyeFan from the dell forums.

"Yea, the 8600m GT has 22.4GB/s of memory bandwidth when clocked at its correct frequency of 1400MHz (700x2). Instead, Dell (and a few other manufacturers) have decided to cheap out and have the memory clocked at only 800MHz (400x2). This results in about half of the memory bandwidth, which creates a serious bottleneck for the GPU. It's effectively starving it of data to process.

The problem isn't the fact that it's clocked low, it's the fact that Dell listed specs that would correlate with the higher clocked version, but deliver the slower one."


is sager2090 and compals ifl90 one of those "other manufactures" BuckeyeFan is talking bout?
Or does the sager/compal's 8600gt have 22.4BG/s clocked at the correct freq? and are they DDR3?

Help would be Greatly Appreciated. Please. I will never bring up another question bout 8600gt once i understand. ever=)

 

As I understand it, the only laptop model currently available with an 8600GT with memory clocked to 1,400Mhz (700x2) is the Asus G1S. I think the others (e.g. Sager, Dell, Compal, Zepto) you asked about do *not* have the same speed video memory.

The distinction between performance of DDR2 v DDR3 is a bit of a red herring, as the key issue is video memory speed, not whether its DDR2 or DDR3, per se.

I may be wrong, please correct me if I am.

You are right, the IFL90 is underclocked... some people say that while the synthetic benchmarking will show a big difference, the difference in real gaming will be negligent. However, this statement is largely without proof.

edit\\ also check out the g1s GPU temps

they are well into the 100's under load!

 

ahh, so their is no big difference.
when does the 516mb over 256mb come into play? does having that extra memory on the sager/compal's 8600gt make any difference in real life gaming?

 

the 512 vs 256 is pretty much a non factor right now, because current games dont dip into that extra 256 much anyway. Once newer games that demand more itwill help, assuming the 8600gt itself is capable of playing them of course.

 

Either way, the 8600GT is the best card for 15" laptops and it is better than previous generations, so I doubt you'll be very disappointed with either one. I went with the compla ifl90, because the 1680x1050 screen was available in matte.
