Official AMD Radeon 6000 Series Discussion Thread

the numbers do lean towards a possible rebadge, but 'cypress' itself seems to have been redesigned here, at least in terms of the shaders.

even so, if it is a rebadge, the thing they did right is kept the 32 ROPS unlike cutting that to 16 in the 5830, which should let it keep a large whack of its full cypress goodness.

 

[cadaveca]

not sure on caymen but I'm going to go with "the numbers don't lie" on barts. Obviously caymen then would ahve to be something newer as barts is already using the cypress core.

Hmm, cayman islands are 3, one big, and two smaller ones. Maybe cayman is multi-chip.

Good point

Yeah, it's kinda interesting...could directly represent Cayman products, two smaller cards, and one big one ,about the size of the two smaller put together...but could also represent something else...who knows. The actual details could be anything, and I'm not in the mood to speculate too much today...freezing my nuts off outside as I type.

6000 series = More Power. Win

Maybe the higher end 6000 series card, especially if you're looking to spend 6-8 hundred dollars. (;

That's a good point and iirc AMD mentioned something like that some time ago, even before rv770 I think. The idea was a full chip that would make into the mainstream card, and smaller chips containing only the shaders and other executing parts that would be added to make biggest parts. That way the entry/mainstream would be 1 "big" chip, mainstream/performance 1 big + 1 small, then 1+2, 1+3 and so on. But after that rv770 was released and I thought the idea was abandoned. I think that the idea returned in rumor form before Evergreen was released, but it wasn't that way either, so the idea was abandoned again. And tbh I'm not sure how that could work as you might be exchanging relative complexity (read manageable) inside the chip for unforeseen complexity on the PCB if say your competitor manages to outclass your products and you end up needing 6+ such chips on your card. Not to mention that the uncore would end up being either overkill for mainstream cards (= higher prices and low profitability where it''s most needed) or fall short for high end parts (rendering the addition of more smaller chips pointless).

Yeah, I remember those ideas...but i think, 5770 is dual-engine...there's two gpus mushed together right there. It doesn't have to be multi-chip, as in multiple pieces of silicon...Cayman may take 2x BartsXT, smushed together on the same silicon.

I'm currently testing looking at feeding shaders, and how multi-gpu scales, and while every singel app so far is affected, few are affected enough such that the game becomes unplayable.

With that in mind, multi-chip, and the latency added there, may acutally make it a bit easier to keep the gpus fed...and AMD already does multi-chip cards.

Who knows how it will go...at this point, there's too many possibilities, and too many rumours.

Soooooo... I should go sell my 5870 now, right?

 

[erixx]

How long was the "I am GODDDDDD because I have card "NAME" period of grace?

3 months, six? Many of use are going to be loosing our godliness soon.... time to open a beer

T'is only a fool that cries 'Godliness' on a tech product. Just means they have bigger pay packets or live at home with their parents.

I am neither but I may trade off my 5850's for a single high end 6 series.

Or they have a wife who thinks they're retarded... :shadedshu

I'll rock the 5970 until the 7000 series is out.

 

[erixx]

hahaha, cheers for both, good for you. I update every 2 years or so, and i will wait a looong time before moving a finger hahaha

That is what I did, is rock my 2 x HD 4870's in Crossfire, skipped the HD 5800 series for the HD 6800 series which should have been based on Northern Islands brand new tech, but instead we have the Southern Islands all thanks the the 32nm messup

On topic what for me is the most important that i hope ati gives the lower models back the double precision capabilty since all models below 58XX lack them now.
Making them useless for my personal use, i hope the 6XXX series will get a bit faster memory or 256 bit wide bus as was leaked but time will tell

what is that?

 

[Bronan]

Double precision is used for some calculation since your familiar with distributed computing, the project which made ATI world famous.
On boinc we do scientific research for different projects one of them is milkyway which uses DP (double precision) for make much more accurate results.
At first this was primarily done on cpu's and nvidia cards since they had a platform called CUDA for use the gpu for do some part of the actual calculation.

I allways said that an ati would do well on this but in my search did not find a way
Now someone called gipsel found a way to use the ati cards and then a revolution came.
A unit on a cpu takes about 10 to 24 hours on a ati gpu that same unit is done in about 3 minutes

On milkyway there is a need for more secure work and what we do there is with thousands of users in 1 day ( on ati gpu's) is like what 5 supercomputers can do in a week

In the use for scientific work in boinc a user deliver his result to a server and in turn this result needs to be checked by another user since it can be incorrect on single precision.

On double precision there is absolute no need for recheck since the result is perfect.
Now single precision is say the 2 cilinder machine on boinc and double precision it is the v12 on this work.

I'm really keen to see what the 6000 does for the mobile market, but really we might need to wait for a 32-28nm die for something a lot better than a juniper core in a laptop, considering the juniper replacement is supposedly quite hearty at 32 ROPS, 960 sp's and 150w TDP....

 

[Bronan]

I think the laptop market is gonna be another line, as i see those will be more gpu and cpu on one die which would be a good step for the laptop market especially if they can shrink the die more then they do now

the problem I see with that is that the on die GPU's lack power, like immensely... good for HD decode and Aero, and just touching on light gaming but nothing more.

whereas the Mobility 5650 in my current laptop does just fine for itself, and I don't see a GPU of that calibre or better (performance wise) making it onto a CPU die for at least another 2 years.

Heres hoping that I'm wrong

This is exactly where I was/am at too. I have kept my 4850's rocking along waiting for NI, but I am starting to think that I will have to grab a 6000 series (or maybe a pair of 5850s after a price drop) to keep up. Mafia II seems to bring my 4850s to their knees. DAMNIT.

Nah amd has showed some already they get awesome performance and whats even more fun is that on die gpu overclock this far insane
I have a old 780G and the gpu (HD3200) is in the NB which i already have overclocked from 500 to 900 but i think 1000 or 1100 will be possible also.

I have to see that to belive it, and the HD3200 and HD4200 IGP's are pretty underpowered by my standards. 80 sp's is hardly enough to use for gaming purposes, IMO with current AMD GPU architecture you need at least 320-400 sp's then your talking.

 

[Bronan]

Google for it many have posted results from overclocked igp, but i seem to lost the page which is for you more relevant which was showing amd the new on die gpu
Now ofcourse if you play crysis it won't work with high settings but what they showed was 5 x faster then the intel on die gpu.
Ofcourse we have to wait till we can see them with own eyes and see actual gameplay ourselfs

hmm isn't ontario fusion cpu use HD 5550 gpu? i see the demo back a while running avp smoothly
