Performance difference between 256mb 8600m GT GDDR3 and 512mb 8600m GS GDDR3?

What is the performance difference between the 256mb 8600m GT GDDR3 and the 512mb 8600m GS GDDR3? I don't suppose the extra memory closes the gap at all? How would the difference translate in fps for some games like COD4?

 

After doing some research the 8600GT will certainly perform better, it has 16 more stream processors than the GS varient, even though the clocks are lower they are not by much.

The performance difference will be pretty huge.

Just to give you an idea:
The 8600M GT with DDR2 RAM already beats the 8600M GS by a good margin, and the 8600M GT with GDDR3 once again beats the 8600M GT DDR2 by a smaller--but still noticeable--margin.

 

The 8600GT overall does have faster clocks meaning faster speed and processing of the chip however the extra memory on the 8600GS can store more uncompressed textures allowing you to play at higher resolutions and more eye candy turned on. However, I doubt the 8600GS can use all the 512MB of memory effectively.

 

The 8600M GS is the mobile 8500GT.

Like proven on my benchmarks for the desktop version, the shader power of the G84 (8600M GT, 8600GT/S) compensate for it. The 8600GT 256MB GDDR3 is 2 times as powerfull as the 512MB DDR2 8500GT. That should give you an idea

 

The 8600M-GS is actually a G84M core, just FYI.

And yes, you'll be looking at around 150% the performance of an 8600M-GS with the GDDR3 8600M-GT.

 

That's not what laptopvideo2go modified inf say though

NVIDIA_G86.DEV_0425.1 = "NVIDIA GeForce 8600M GS"
It has the same specs than the 8500GT anyway so.

 

That doesn't really have anything to do with anything though. The 8600M-GS is indeed a G84M core, as it has 16 disabled stream processors on die, which would be impossible for a G86M core. I don't know much about the 8500GT, so I'm not sure what core it has.

 

The reason nVidia lists the 8600M GS as a G86 in their driver's inf is so that it can take the settings of the G86 since it has 16 disabled stream processors. Otherwise it would run at possibly damaging settings, if it is trying to access disabled stream processors.

This discussion has already been done several times. The 8600M GT will outperform the 8600M GS in all instances, simply due to the 16 extra stream processors.

BTW, the 8600M GS actually has faster clock speeds than the GT for one person who posted that the 8600M Gt has faster clocks, it does not.

Given an 8600M GS with GDDR3 and an 8600M GT with DDR2 the 8600M GT will still win.

 

Fixed that for you .

 

red vs blue? color wins!

 

LOL, thanks Odin, I never realised what I wrote then but I was thinking it

 

I have 8600gs 256 GDDR3 and it is quite good, runs crysis on 1024x600 and nearly all med. I am satisfied
