640GTS vs 320GTS ..... Are these true?

[Blitzen]

Well...here we have it from a well respected test site.
I dunno if these figures are true or not but read the WHOLE article and you will see that as far as they are concerned, the extra memory was of little consequence and its drivers that are the key.

Even in Crysis, with the new set of drivers, the 640mb version will give no performance boost over the 320mb. So, at resolutions on screens 24" + there may be a difference (i couldnt find a test to prove or disprove this). On a screnn 22" and under, regardless of the game you play, whether its PacMan or Crysis, the 640mb version is no better (and in a few instances worse, then the 320mb.

See here: http://www.xbitlabs.com/articles/vid...oundup_17.html

In fact, in STALKER, the 320mb version actually performs BETTER @ 1600x1200 and 1280x1024 .

All 3d Mark Score differences are negligible aswell.

From what i can see, the GTX and Ultras (little diff between these), do stand out well, but 320mb vs 640mb is well and truly blown now if this review is to be taken as read (no reaon why it shouldnt be).

Looking at it then, it was just a driver issue and not having them optimized correctly which formed the myth that the 320mb took a performance hit over the 640mb.


In the end, i dunno if i believe what they are saying or not as, like with most reviews you read, there is alot of conflicting evidence.

this is the reason nvidia were saying that they will ditch the 640mb of the 8800gts soon as it has no real difference over the 320mb

tradionally, more ram on a board has often been marketing hype.

Geforce1's with 128mb
Radeon 9600's with 256mb
It's too earlyon a Sunday tomake my brain work for the list, but it's virtually endless. As ever....bandwidth of the ram (mem controller and ram speeds) are king.

One day it'll be worth it, just maybe not on these cards, right now.

here...cop this:

http://www.scan.co.uk/Products/Produ...oductID=417317 a Radeon 7300 with half a gig!!! £86.35

http://www.scan.co.uk/Products/Produ...oductID=519985 7600 GT with 256mb £81.50

Guess which is faster in everything, including making breakfast.

It's not the size mate, it's how you use it!

Was there ever any doubt?.. Most of that RAM is wasted space.

Utter rubbish

I did have a 7900gt 256 and in some game it would not detect my screen size I was using (1680x1050) plus it would not let me have AA and all that on but after getting a 7950GT 512mb (RMA) I could play at my screen size with all the bits and bobs on

The bigger the screen size, you are better off having more ram onboard

[aidanjt]

VRAM has no bearing on framebuffer size, unless you only have like, 1Mb or something stupid.

yes, but 1680x1050 is not a huge screen size is it?

Well......the various testing houses/sites around the web know quite alot more than you do i suspect

[eddta]

YES. My choice not to pay for the extra RAM was correct and now I am the smart one for once.

Lines?

[twoblacklines]

whatabout games that wont do high res textures with less than 512 detected vram ?

Email the site that wrote the reviews ...... they will have the answers.

Never known any!
Need links!
Sure thats not pre 7 & 8 series nvidia cards?

[jackvdbuk]

doom3 i thinkis one, and most suggest atleast 512mb gfx ram
