With TDP and Max Res this time

Ooooohhh - me likey! I was going to replace my HD4850 with a HD5770, but if these are likely to come out in Q1/Q2 of 2011, i'll hold on that little bit longer and get one of those instead

[K404]

I want 68x0 numbers

NDA lifts on the 18th, expected in retail chains by the 25th October.
Or so the word on the net says.

Question is, do you want to upgrade now and get a massive performance increase or wait til christmas for the Cayman part?

Tough choice.

Due October 25th apparently

[Dimitriman]

It's looking good indeed but Im not buying anything until Bulldozer/SB 2011 and full Northern Islands.

[Mechromancer]

A $220 6770 would be fantastic. Unfortunately it probably won't be that cheap outright. It seems we will get better value in the mid-range segment from AMD this round so HOORAY!

[dengyong]

So where does twice the horsepower come from ? I don't see it in the specs... someone educate me please.

maybe no need to wait if there's a good CF setup under 400€ like with the GTX460

[Kai Robinson]

I'll get a 6770 on launch or near to - i cant afford more than about £175.

Barts XT = 6870

Barts PRO = 6850


Barts retail model is indeed a HD6800

PRO is the HD6850, XT is the HD6870, I had the second edition of the Roadmap that the basic is the ultimate edition. More

Double the stream processors.

[spursindonesia]

Double the stream processors.

And double the buswidth too. Let's hope it won't double the current price of Juniper cards.

i still call bull on that. naming is the last thing decided and roadmaps wont tell us for sure the proper name. at this point pr slides are a lot more reliable.

The chart above says less than the 5870, does it not ?

Maybe I'm missing something from this picture.

You are comparing a 5870 to 6770 when everyone else is comparing a 5770 to a 6770.

[Calmatory]

More ROPs translates to more peformance... Lovely. But HD68xx.

Well that clears it up. thanks

Double the stream processors.

it can only do 70% more theoretical math. but then again this is a new shader architecture so we cant be sure if it is 2x faster yet.

[highoctane]

Hmmm, finally looks like I may be replacing my 4850 with a 6750, curious to see the performance numbers now...

[Jowy Atreides]

But multi gpu setups are still plagued with sync issues.

Single gpu for stability

It'll probably cost more than that for the 6770

Higher clockspeed and memory.
