6770 & 6750 Specs leaked

[blindbox]

lol yeah ^^
Tripleposted x.x.

Maybe the forum should install an automerger?



In fps numbers, yes.
In actual fluidity, no.

Games are jittery with multi gpu cards.
So that extra 40fps or whatever you gain with a second card has the visual effect of gimping you to the smoothness of 15fps on a single card.

Go read:

25fps single card is better than 50 on sli

The thread you gave is pure win (I read it before you posted). Anyway, there's a microstutter index threshold (it's in the thread somewhere. Above 20% is bad IIRC. Then again, the threshold might vary with people) before the motion becomes non-fluid aka microstutters.

i think we have reached it

microstutter you have to work to see it and if you change settings it's gone
i've had x1950cf, 3870 cf, 4870 cf, 4890 cf and 5970

I want 68x0 numbers

Well you just looked at them.

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.

Barts is being released on Oct 18th with massive availability.

Surprised that no one has specifically pointed out the confirmed change from a 5D shader to a 4D shader set-up.

The chart is not completely real...

That disclaimer proves nothing about naming. The launch guidelines could cover quite a bit

He is right though, well about the naming.

[TheBlueChanell]

I'd be willing to bet that barts pro/xt will be 6750/6770. There isn't any reason for AMD to change their nomenclature for this generation.

Hemlock 59*0 (New this generation)
Cypress 58*0
Juniper 57*0

Antilles 69*0
Cayman 68*0
Barts 67*0

Unless they're are planning on releasing a load of different variants, I'd sincerely hope that they'd stick to the scheme they just finished establishing this cycle.

can i see a screen shot of your account balance? not doubting you in anyway and dont want to see anything that could hurt your identity but i just wanna see 7 figures.

The 2gb of ram, budget videocard and asrock MB don't really inspire confidence.

If AMD turns barts into a 6870 parts, those who criticize NV for renaming practises better drop the hammer down, because this is just as bad if not worse a move because you may be getting worse performance. Compounded would be the that this move would be entire be fueled by increasing the margins rather than survival.

Its not certain, but the increase in card size along with some people saying it is true, it could really come as reality.

I for one will not try to be uptidy and claim I won't buy AMD anymore if it does turn out to be the case.

To me, those specs in the OP really dont look like *7** range cards at all. Even if they are, they are going to cost the same as the 5850 currently does, no way is that 'Barts XP' card going to be launched at the <£150 price point where the *7** range is supposed to be.

And more lulz over the Microstutter BS in this thread. I've been through crsossfire 3850s, 4850s, 4870s, 5770s, and SLI 6800s, and GTX 460s, and never seen any kind of microstutter in any game.

The vast majority of the people who complain about microstutter havnt even used multi GPU setups themselves, they pull out info about microstutter based on what they read around the net with no personal experience of using crossfire or SLI.

I would NEVER go back to using a single hot and noisy card over two cheaper mid range ones that perform better with LESS heat and noise (two GTX 460s = FAR FAR less heat + noise than a single GTX 480, anyone that believes otherwise is completely clueless).

[bamtan2]

a lot of people here are pretty sure of things they dont know.

what I do know is that the rumor about barts being 6800 and 5770 being renamed to 6770 was very creative if false...

[halfwaythere]

A lot of folks hung up on the naming. Why? Maybe they want to keep the x7xx naming scheme for the 128 bit parts. Also why would one be mad if hes getting the 58xx performance in the 68xx at a lower price.

[zanzabar]

u guys missed the best point, the 5870 is 320x5 so 320 physical shaders and 5 scalier units per physical shader and the other cards from the hd5 all also have 5 scalier units per physical shader, but this lists the 6770 to have 320x4, we know as of now that the shaders are not efficient since they have to many scalier units per physical shader so it will be interesting to see how this works for clock speed and performance.

I totally agree with you on this concerning air cooling, for air cooling the GTX 480 is a fail but for water cooling users the GTX 480 is cheaper than 2 GTX 460 and some if not most 2D and or 3D programs does not use the SLI capability and also half of the memory is lost with SLI. So for water cooling users a 480 GTX would be the best choice yet.

http://www.techpowerup.com/reviews/N...60_SLI/25.html

SPARKLE GTX 480 1536MB = $439 http://www.newegg.com/Product/Produc...-109-_-Product

MSI N460GTX 1024MB $219 http://www.newegg.com/Product/Produc...82E16814127510

The GTX 480 single can be used at full for any application also has 512MB more video memory but GTX 460 SLI gives to games and applications when it works 13% more performance but you pay 40% more for another waterblock.

In the end they have the same outcome, is a matter of preference and for what will be used. Well like the marketing BS 'Fermi done right', Nvidia will get your money both ways and they know its a draw.

on topic: The specifications of the ATI 6800 series look good, prices are needed.

[tajoh111]

I am just wondering. If they removed 1 shader out of a 5 shader unit to make it a 4 shader unit. How is their a 25 percent area savings as rumored? Assuming they removed one of the simpler shaders not capable of double precision hence the efficiency not dropping that much, how is their a 25 percent savings since these simple shaders are thought to be rather small compared to the more complex shader 25 percent sounds a tad high.

[LordEC911]

What would you like to wager? XS membership? Mine is coming due here pretty soon.

those arnt real shaders they are like hyper threading, that should not save die space like that, so it can do 5 (or now 4) normal commands that all have to set at the same time or 1 complex command, it should save power but not die space

[Solus Corvus]

Specs are interesting if true. I wonder what else has changed besides the shader/rop/tmu layout. Did it get other NI features also? Is it an un-shrunk NI or the rumored frankenstein? I guess we don't have to wait long to find out now.

If they are indeed calling a Barts part 6870 I can't support that. I can understand, from a business perspective, why they might want to fill out the 69XX range instead of jumping from 6870 to 6970. But IMO it doesn't serve to clarify anything and will only end up misleading the typical uninformed customer. Their top single chip card has been X870 for a while now and should stay that way, IMO.

Going off topic here, but... Don't judge a book by it's cover. My uncle has a multi million Rand house (converted to dollars, a few hundred thousand) yet he drives a Toyota Avanza and his PC is an AthlonXP 3000+ with 256MB RAM. Why? Because he doesn't have a need for an expensive car. Because his PC is more than fast enough for his needs. Not EVERYBODY's priority lies in having the most expensive hardware, and even though this is XtremeSystems I can guarantee you that a lot of members with low spec PCs can afford something better but choose not to

[zerazax]

This thread has all the trademarks of a near-release GPU thread

[qcmadness]

Renaming is not acceptable for whatever reason.

[saaya]

hmmmm why is the 6770 running the mem at only 1050?
less tmus, meh :/
awesome tdps!

if this is priced anywhere near 5700 cards this will be very tempting!
gtx460 what?

EDIT: wait what? barts is 6800? 0_o

[MrMojoZ]

EDIT: wait what? barts is 6800? 0_o

The biggest remaining question. I hope not.

[Calmatory]

What? The new 4D system allows ~98.5 % of the performance at ~75 % diespace. So they can put 25 % more shaders to the same die area, meaning more theoretical number crunching capability per mm².

What I suspect is that AMD isn't really going to just put 25 % more shaders to the core, instead focus on ROPs, TMUs and memory bandwidth because there are bigger bottlenecks there than in raw number crunching.

[Lokinhow]

maybe...barts is being called HD6800 because of its tesselation performance?
I mean, barts is slightly slower than cypress, but with tesselation it's (supposedly) much faster, so AMD decided to call it HD6800 and not HD6700?

[Sn0wm@n]

LOL how can people know how fast or how slow it is without benchmarks ... LOLL

[Manicdan]

LOL how can people know how fast or how slow it is without benchmarks ... LOLL

you keep pushing settings till crap starts to get laggy, ive done that on dozens of games without ever running fraps

i probably spend an hour just playing with graphics to see what all the options do. which ones provide ME with the best eye candy i want.
boob bouncing needs to be an option in every game

[kazuyakun]

LOL how can people know how fast or how slow it is without benchmarks ... LOLL

My crystal ball told me so... Anyways I can't help to think the disclaimer to be nothing more than a typo, I remember the 6700s were first to launch not 6800s...

[Sn0wm@n]

so your crystal ball told you so ??? cool .. i want one because obviously someone left me out of the loop on this one ...

the same thing happened for fermi ... it was suposed to be here so early be a massive super uber monster and the hd5K series was suposed to be some cheapo stuff ... yet its not the same thing that happened ... so we should all wait to see if the rebrand rumors are true or false etc.... anyway ... its not like its another 6 months of waiting .
