AMD leading in the transistor size race? WAAAHHHhhhtt?? :) Sounds like some good news. I, for one, am tired of hearing about bail-outs and company lay-offs.

I'm wondering what the OC potential is for this card.

So this will show us the difference between GDDR5 (twice as fast) with a 128bit bus (half as wide), and GDDR3 (half as fast effectively) with a 256bit bus (twice as wide)?

just what i was wondering. it's possible it might be constrained due to not having an external power connector. it's good to know that if you can stably push the memory clock to 900, it will have equal memory bandwith as the 4830 and thus will easily outperform it.

i'm very tempted to buy 2 of these for cf to replace my 4850 because even 2 of them should be fine on my 500w psu whereas a 4850x2 probably will not. and the performance will be close too, approx 1.8 gflops (900x2) for the cf'ed 4750's vs. 2 gflops for a 4850x2

Also it uses GDDR5 instead of GDDR3. I find the appealing part of this card to be its power requirements which are quite low compared to other cards today.

The preliminary tests done on this very card are done by Guru3D,

Everything in that testing puts it's just shy of the 4850 by about 5 - 8%, not to mention they claim that AMD said the price will be in the budget range of 90 - 100 euros.

I just have a feeling they stole it directly from there TBH, the price tag seems even more wrong.

Can't wait for this card, it's going to replace my HD4670. :p
Hopefully it'll cost around the same the HD4830 costs now...

They're talking about calendar year, so Q2 = April 1 - June 30. Hopefully closer to April 1, but lately tech companies have been squeezing it in at the end (I'm looking at you, Nehalem).

[citation][nom]shabodah[/nom]Why isn't nVidia using GDDR5 yet?!?[/citation]
AMD invested into GDDR5 2 years ago. nVidia hasn't so they have to design a card to utilize it first and that takes more then a year.

Seeing that AMD only chopped 5nm off the process, it looks like they discovered the limits of their fab,without having to rebuild their equipment.
from 45nm to 40nm isn't as good of an improvement as from 65nm to 50nm, or 50nm to 45 nm.
it's about a 10% more efficient,or, for the same power can be upto 10% faster.
Only a pitty they didn't focus on the 4660 and the 4850!
4660 due to it's already low powerconsumption,and the 4850 because that's what most people want to buy! (not the previous technology!

You would've been correct if not for the fact that the current fab sizes of both ATi and nVidia are 55nm.

The AMD CPU is 45nm, the GPU isn't. And As far as it's known, the 4890 (to come in April) is still made on a 55nm fab.

And the preliminary testing gives it JUST shy off the 4850, for alot cheaper, so yeh... it would help to read more Websites about this stuff next time :)

Ah ah heck... i meant with the above preliminary testing the 4750 ofcourse (name in fact still is unknown and was guessed to be as such)

The 4890 is supposed to be not too far from a GTX285.

The 5XXX series AFAIK is planned for the 40nm build.

i have a Toshiba sat with a radeon HD card, the only way i can re-install a corrupted driver is to reformat my entire computer and bring it back to stock settings.

ATI has ABSOLUTELY THE WORST driver support on their webpage. Dont bother with this company, its rubbish.

what difference is it going to make?
ati cripples their memory bandwidth with half the memory interface of competing nvidia cards
as long as it gets the right performance, I don't care what type of video ram goes into my video card

I have a Toshiba with a HD2600, I updated the drivers to 9.3 using a modder... and it works fine... Maybe u should try to figure what happened to your pc, instead of making such comentaries...
