8600m GT ddr3 - 256mb vs 512mb

Sorry to be another one who bites the dust in the "this vs that" threads, but I really couldn't find anything about this. So I have some questions:

0) Is there a 512mb 8600m GT with DDR3 (or GDDR3 whatever the difference is) ?
q) If so, would the 512mb one USE all the memory that's there?
t) Does anyone have it, and/or some benchmarks, maybe?

Cheers!

 

ddr3 describes ram gddr3 g= graphics. You probably won't see any major difference between 256mb and the 512mb.

 

there is no 512mb gddr3 version of the 8600mgt. if there was then yes it would use all the memory.again there is no gddr3 512mb version so no benchmarks

 

Here is a benchmark with my 512mb DDR2 GeForce 8600mGT (Stock score is 3893)

 

What driver are you using? I believe people with a 256mb 8600gt gddr3 don't get over 4500 in 3dmark06?

 

thats at 1280 x 800 not 1280 x 1024 thats why.

 

Well, thanks, but my original question was about the 512mb DDR3. Seems there isn't such thing.

But if there were, could you feel improvement from 256mb to 512mb (DDR3)? Because I read somewhere that DDR2 can't really use all of the 512mb,

I'm just wondering if a DDR3 COULD in fact use all the 512mb, and would it be faster than a 256mb...

 

yeah u would see an improvement. the ddr2 8600gt cant use 512mb but the 512mb gddr3{if there was such a thing} could

 

If you read my last post, I said my stock is 3893. It's almost 5k because of overclocking and raising cpu voltages.

 

No GDDR3 is always going to be faster than DDR2. Don't worry about the extra 256MB. It won't make a difference.

According to the Apple website the new macbook pros have GDDR 8600m gt

 

Yep I was about to post that... but I think the Macbook Pros are the only ones with GDDR3 512mb 8600s right now, since everyone seems to think they don't exist.

 

if there was a 512mb 8600m gt you would see little to no performance increase

 

Well there will probably be benchmarks on the new MBPs within the week... so we'll soon find out. I expect the difference to be minor though.

 

Yup. At 1280x1024, his score would be very similar to stock 256MB DDR2 cards.

 

doesn't the refresh mbp have 512 gddr3 now?

 

That's what the previous 4 posts have been about...

 

Yeah but the extra ram will not do much if anything at all.

 

I think it's useful for games with a ton of textures (Oblivion).

 

Voltages don't help performance. I undervolt and have the same performance. Nice scores though. What are your clocks?

 

whats the consensus on this then? Some are saying an extra 256mb will help whilst others are saying it wont!

How can we say if something is fast enough to utilize a certain amount of RAM? Is that not purely guesswork which in itself has no credibility?

 

I love telling people my 8600mGt has 512 ram.

Even if it doesn't help..

 

lol, i used to do that but the effect is much less pronounced with my go7300

 

128-bit buswidth with 512Mb video memory is like a huge pool of water with just a sinkhole to drain the water, i.e. lots of video memory is nice but the buswidth hampers how much data is being processed at any given time. A 512MB card vs my laptop card would probably have slightly better fps at resolutions 1680 and above with all other settings equal due to the increased video memory helping to load all textures in place before being slowly displayed on screen due to the limited buswidth.

Read narsnail's thread on the differences between the 8700GT and 7950GTX since his explanation on the importance of buswidth in video cards is better than mine.

 

on 1280 x 1024 3dmark 06, i've gotten 5404 with my 8600gt gddr3 sony vaio ar don't kno how to post pictures but yea gddr3 is quite powerful

so i wud suggest u get a gddr3 rather than 512 gddr2

 

Hey guys I'm thinking of getting a mac pro -I have a choice of 256 mb or 512 vram. How much difference does it make?

lol whoops my bad..I also just realize there was a post at the bottom of this page :S
sorry

 

Well, it depends, is the 256mb version a DDR3 version, or DDR2? It's almost a given that the 512 versino is DDR2, but if the 256 version is DDR3 it's definitely a noticeable difference.

 

its all good. just hope the mod's don't get mad.

 

hmm im not sure if anyone has mentioned this in this tread...but the new macbook pro's are Gddr3 8600gt 512vram...check it out for your self on their site.

 

Only a bajillion times.
