Question about the usefulness of 1gb of GDDR2 RAM on a Geforce 8600GT

post #1 of 8
Thread Starter 
Greetings. i was wondering exactly how useful 1 GB of GDDR2 ram would be on a Geforce 8600GT.

here are 2 Geforce 8600GT options, 1 of which i was planning to get:

EVGA 01G-P2-N795-TR GeForce 8600GT 1GB 128-bit GDDR2 PCI Express x16
http://www.newegg.com/Product/Produc...82E16814130341

EVGA 512-P2-N756-TR GeForce 8600GT 512MB 128-bit GDDR2 PCI Express x16
http://www.newegg.com/Product/Produc...82E16814130292


I was told by a poster called 'amtek' on the evga.com forums that:

"Just one comment about the 1GB model of these cards. While they are decent in speed, theres really no way you can take advantage of 1gb on memory with these cards because gaming at the resolution and detail that WOULD use 1gb of memory, would not be possible with the 8600's processor. Its kinda of silly that Nvidia is now adding 1gb of memory to all mid-range cards with 128bit interfaces, while the high end cards like the 8800GTS (G92) and 9800GTX that could possibly take advantage of the extra memory remain at 512mb."


This statement exceeds my knowledge and i would love to hear what more experts think about this. is it really true that the 1GB of GDDR2 ram on the geforce 8600GT is really wasted, or could it possibly come into use at some point? am i just better off getting the 512MB version even if its only $20 cheaper? Do i neccessarily have to be gaming in huge resolutions like 2560 x 1600 to actually take advantage of that much RAM, which would be useless because the processor on the 8600GT cant handle those resolutions?

thank you for your time and i appreciate your help.

1GB on that card is a waste. I'm building a rig right now where I will be putting two of those with 256mb vram on each card in SLI, and that should be plenty for even that usage. They companies that add this extra RAM do so for the uninformed, who think that a bigger number for the video ram is equal to more performance.

Get the 512, save some money. You won't find a game which will utilize 1GB of memory at a resolution that the 8600 will actually be able to display.

Go to tweaktown's website and read the review on it... (gddr2 sucks even with 1gb... very low benchmark)

plus its only 128bit... low end 8800 run at 256bit minimum

Amtek is dead-on correct.

And personally I'd go so far as to say that if it were around the same price as these two, I'd prefer a 256MB card with DDR3 any day of the week, all else being equal of course.

I'd take a look at the new 9600GSO, that should be out shortly, in the same price range, and will BLOW DOORS off of any 8600 model. The 8800GS is pretty much the same as the 9600GSO as well, if you can still find one of those, that is a better choice as well. Hopefully you are learning something from your question and our responses ... more memory on a video card is *NOT* necessarily better (when comparing across different cards) by any stretch of the imagination...and even when you're looking at two cards that are otherwise identical, there are cases where extra memory is next to worthless and would be only be recommended if the prices were literally identical. This is one of those times...

thank you guys very much for your help! it really sucks that NVIDIA has decided to add so much more memory to cards that wont even see the benefit of it... like the higher end geforce 8 series would be able to benefit from such 1GB ram but not the middle tier cards.

good point, i guess you are right, it surely must be a marketing tactic

thank goodness i was able to get the help of such experts like you guys, i didnt understand that the higher the RAM on the video card doesnt neccessarily correlate with improved performance. good thing you guys talked some sense into me and i appreciate it!

the 8600 series cards are not designed to handle that big memory and another drawback, its DDR2, definitely not worth the money and there is absolutely no use for that gig of memory and the same goes for the 512mb version.
