View Full Version : GTX460 1GB vs GTX460 768MB
Ok so now the price of the 768mb is under £100+ vat i am sorely tempted BUT am i right in thinking there will be a slight performance drop compared to the 1GB version due to the 192bit v 256bit memory interface? Been a whilse since i looked into highish end gfx cards seriously.
From looking around its only a few percent at most in games, is this right or are the comparison reviews a bit misleading, its not like i am a hard core bencher afterall, and for £100+ vat i am almost tempted to double up :surprised:

the main difference kicks in when the resolutions get higher. if your using 1920x1080 and up a 1gb 460 is probably better, not essential though as the 768mb version will still play the games ok.
The 768mb is about on par with the 5830, the 1GB is then better than these and < 5850.
Yeah if oyu look at some reviews it does have a lower fps, but not by enough to warrant the extra price on the 1GB, especially as the 768 is so cheap.
I have a 768 GTX460 and it plays all my games fine on high at 1920 x 1080, OC's to 866 from 675 on the core as well, besting a 5850.
As El Wayneo says, a heavily OC'ed GTX460 768mb will best the higher cards.
Yep i agree with the above posts, you lose 4 ROP's too between 1GB an 768MB version only really matters at high resolution when alot of AA is applied.
Take a look here...

for me there would not be enough of a difference to justify the higher cost of the 1GB card.

Just SLI a couple of those bad boys :)
Yeah pretty much as i found in the linky, most games at higher res (19x12 which i game at) and lots of eye candy the 768 loses out by less than 10% most of the time, as mentioned hardly justifys the extra cost imho, specially when the cost of 2x 768mb is about £50 more than the cost of 1x 1GB version.
Hmm desicions decisions. . . . .
what have you currently got mate?
depends how long you plan on keeping them imo, if its for a year then the 768s will be fine, if you want it for maybe 2 then the 1gb will serve you better as i have no doubt those few % now will help more as new games come out.
I see your point, but its £40 atm though for those extra couple of frames.
Plus Mafia II only uses around 450mb and BFBC2 around 700mb.
Theres no drastic new games engines coming out soon so 2 x 768mb GTX460 should play any game fine next year at 1920 x 1080.

GTX260 (216) if my memory serves ;)
thinks its seriously hard to argue against getting 2 768 460's at the moment, brilliant performance for the price

I've not checked, but does the extra rops etc not gain much at 1080?

not really its about 10% with 4 less ROP's but this could change in future games if bandwidth restraints kick in.
2x 768MB 460s in SLI with current prices sounds like a great move. Just make sure your board can operate at 8x/8x as opposed to 16x/4x.
it was the rops (and mem bandwidth) i was thinking of more than the extra ram tbh which would help more down the road.
But overclocking shows that the memory has little gain in getting more fps.
When you can gain 15fps ocing the core, the 5 extra you get from the 1GB don't matter anyway, the min fps is going to be practically the same.
what have you currently got mate?
Currently got a GTX260BE, tbh only game that i play regularly atm is bad company2 which it plays "ok" but not much aa is on, think detail is set to max, and its obviously "only" DX10.
Still only toying with the idea atm.
Also would possibly be keeping them a while, had the 260 for 2 or 3 years now, unless something else comes along which is as seemingly as good a deal.

Yes it does do 8+8, have a gd65 + i5 @ 3.8ghz, though 4ghz is only a quick bios trip away :thumb:.
I went 1gig felt it was better in the long run & if they drop as much as the 768 I'll get another sooner.
My comparison of a GTX 260 (192c) versus single and SLI GTX 460 768MB cards HERE (http://forums.aria.co.uk/showthread.php?t=29875).
The lower memory does hurt, but only when you're playing with high levels of AA at which point neither card is going to be spectacular to play with.

I tried 460 sli on my Maximus Gene II it wasnt much faster than a single card in 3dmark or vantage maybe it was running at 16x/4x rather than 8x 8x?
It could have been, I hear the 460's scale very well in games as well as benchmarks.
