hmmmmm yes thats even more obvious than the 5870 to 4890 comparison...Quote:

really weird...
could it be that the reworked dx11 cores are slower per clock than the previous ones? they must be notably slower though...
i mean the 5750 is almost double the 4770 in specs...
My bet is driver issues and possibly that underclocked CPU... atleast I hope so. Waiting proper reviews, if this thing really is this bad it's a HD5850 for me...Quote:

i think that was 5750 benchmarkQuote:

So 5770 will have similar performance like 4870? :) I like this :D
Between HD4870 and HD4890. Sometimes more, sometimes less.Quote:

still not enough i expected 192 bit at least damn this card has some fine specs :(Quote:

cant be THAT much of a diff tbh cos honestly wasn't ati like 90% ready for dx11 anyways ?? and its pretty much the "same" core in a nutshell :/ so imo it should perfeorm vaguely the same...Quote:

Something is definitely off with that performance, but the specs are not bad at all.
Still, for $199 on the 5770, you mind as well spend $60 more and get 1GB DDR5, and double the bandwidth. Have a feeling most 577x cards are going to be 512MB
CPU is not underclocked..... its just Speedstep on an e8400 bumps it down to 6x333 @ stock idle
ahh my bad. well still just odd benches. i still put it down to his setup till i see some more reputable source benching the cardsQuote:

Is there any chance 4770 will have a larger memory interface? seems like these cards could be a perfect replacement for my gtx260's i'd just be a little bit worried about memory bandwidth limitations.
Guys, this is Cypress, not Juniper, the 57's are bad cypress cores.
hence why I'm hoping that the SP unlocker will work with the 57's, 5870 power for $150 :D
the chip looks very tiny, no way its unlockable.Quote:

it looks like alot of the 5xxx cards are under performing, i wonder if they have too much stuff and just need higher frequencys
it's probably the drivers, and by Q2 2010 we'll probably see a 20 to 30% performance increase.Quote:

yeah im not impressed with the performance relative to the amount of change. i could either buy a 5850 for 260+$, or a second 4850 for 100$ and be just as happy.Quote:
