^ ....?

I don't get it.

The thread started by talking about a possible new Uber powerfull GFX card,the kind of stuff proper PC geezers post about, it has now moved on to quantum mechanics which lets be honest is in geeky, student land.
Sorry if ive offended anybody :p

So how big is 1nm compared to 1mm?

Well, 10^-3 vs 10^-9

it's small.

only offended if you called me a mac owner! lol

where did you get your information from?

a electron is about 1000th the size of a proton, a proton is 10 -15 and 1 nanometer is 10 to the -9 (billion)... hence a electron would be 10 -18 which would be 0.0000001nm or here abouts


the problem is not electrons but the size of silicon atoms which would prob make 10nm very hard..

and i think by the time it gets that small things would switch to quantum computers

yep, i was busy helping the kids with some science work and also browsing the forums and confusion kicked in, electrons are super tiny and you have put it they wont be the limiting factor. at 10nm it would be pushing the limits of the minaturisation equipment, there is a limit how small things can get. would a transistor even be able to be made at 10nm?

read somewhere that insted of using electrons they would be using light somehow.

and wait for nvidia to pull out the hidden dragon. :D

Hidden harmless hamster more like :p.

I remember when Nvidia announced that they would blow our minds with the GTX 260/280 :D.

Psychas, Mav with anything ATI won't happen. He's too busy hugging the green to ever give ATI an inch because the AA performances of R600 wasn't good enough (boo flippin' hoo). One dodgy card with every other card doing extremely well throughout ATI's existence and he holds that against them for some reason :confused:. Each to their own but I do think it's a bit silly :).

cyber mav u not upgrading to 4850/70?

not planning to at the moment. lack of game specific profiles is whats mainly putting me off. also the voltage regulator heat, but then again my x1900xt runs dam hot. got it voltmodded to give 1.5v to the core for 700mhz core speed. vrm temps are the nasty ones hitting close to 80c.

was thinking of spending 60 quid and getting a 9600gso to tide me over for this year and see whats available early next year.

although my x1900xt runs GRID ok, the main problem is the lack of vram. only 256mb is really killing it in grid in some races the card ends up stuttering really badly. 512mb x1900xt would have lasted longer but oh well.

if ati sort out thier driver issues and get the game specific profiles working like nvidia have then its gonna be a real hard decision to avoid going with ATi.

Well I think you should at least think of a 9800GTX+ or a 4850 soon Mav as games like Grid loves these cards and you're just missing out on better gaming experiences by putting it off. Try the 4850, sod the game profiles as that is just an excuse. I only use profiles for older games that don't have AA/AF options but even when using my ATI card I could set profiles in ATI Tray Tools so I don't really know what is stopping you?. 4850 for £111 though? (tempting). 9600GT is old news and the cheap 4850 destroys it easily.
 
After a while die shrinks will not be possible as quantum effects will be present. I'm not sure what how far it'd have to get down to for quantum effects for be observed... Anyway...

Back to the topic, great news with the RV870, possibly a worthwhile upgrade from my clocked R600 :p

light is photons right? how big are photons?

I think the limit is 16nm, or maybe 11nm, I was reading about it couple of days ago.
