Would it be a good idea to sell my non-reference 5870 and get a new 6870?
I'm not sure if it would be worth it anyways, because the 5870 is obviously faster, and all the money I get from selling the 5870 would all go towards the new 6870.

Dark-Energy: I agree with ripken204....
The 5870 is a very nice card, I'm still stuck with a 4870 so if the price is right I'll definetly be getting a 6850/70 (depending on price).
IMHO, if I already had a 58xx series card though, I'd wait a while and see how things shake out. The 69xx series should be out in November, if you can wait another month it may be worth your while to hold out and see where prices settle....
Hmm, so I should probably wait for Cayman then
I'm just concerned about how much I would get for this 5870, hopefully nothing under $300 CAD, but maybe that's too optimistic....
Way under 300, that what people are getting now without the new series out even. Make sure you sell on a techforum so people actually know the performance they are getting.
I would sell now if you can if you want max value, but its still really risky because we don't know how much of an upgrade cayman is going to be and how expensive it is going to be. We have an idea of both but nothing certain.
Performance wise 6850 and 6870 are under 5850 and 5870. I think its better to wait for the Caymans before selling any of the Cypress's.
Awaiting members benchmarks...
Even if it is $500 that's still $100 less then a 5970. With 1920 I could see it matching a 5970. So you'd be getting as much performance as the top card from the last generation for less money.
If it sells for $600 then I will be quite disappointed and most likely skip this generation. But what would you say if it ends up selling for $400 like I hoped?
If it doesn't feel like it has enough price/performance advantage over what you have now then it would be most sensible to not buy it. I stuck it out with a GTX285 until I picked up my 5970 for $300.Quote:
I don't think very many people, atleast in the know and remember last generations scalping, are going to be optimistic. I think they are going to expect long last scalping until NV responds with something. I bet alot of you guys that are interested in this card are going to buy at the first reasonable price they can find because they don't want to pay crazy scalping prices like last generation. And that my friend is a pessimism alot of us share I can imagine considering NV competition right now.
Nobody is making you buy these products. If you feel the price is too high then you should not purchase the product. People who have to buy the new product even if they feel it's priced too high hurt all of us by keeping the price elevated. Part of the recent price inflation is our fault for not exercising frugality and rationality as consumers. If a significant percentage of potential customers declined to purchase the product then they would have little choice but to drop the price.
I have been wondering about the NI architecture since it was announced. Rumors indicate it is a 4d design, but of course nothing official confirms that. We shouldn't have long before finding out the truth. I doubt that they would use a different design between Barts and Cayman.Quote:
I was probably one of the only people on this board to question, whether barts or the 6xxx in general was going to have 4d shaders(and barts has a 5d shader). Sometimes pessimism can help you see through hype and perhaps high expectations or rumors.
I try to moderate my expectations. I looked at the rumored shaders and clocks of Fermi and decided 30% faster then 5870 was probably about right. Fanboys from both sides grew a few extra wrinkles from all the frowning. But as it turns out my guess was closer then any others I heard. I always advocate moderating your expectations. But that doesn't mean automatically being pessimistic about everything. It means thinking rationally about the subject and trying to come to reasonable conclusions.
We know so little about Cayman that I have very few expectations at all, high or low.
Because you trying to be a smartass,
Those three are different architectures

I believe now you do understand that 6870 is a reconfigured Cypress. Even AMD themselves said it.
Those of us in Aus have prices already...Some stores even list them as being in stock and available for purchase (But who knows if that is accurate or just an attempt at a price gouge pre-order stunt)
6850 lowest price is $259 (Sapphire)

Where is slide 19?
The rumors have always pointed to NI being a mix of the original NI front-end with the shader core of the previous generations. Nothing has been wrong.
First, you can already see that G80 and GT200 are pretty damn identical, so it's hardly 3 different architectures :rolleyes:. Fermi is of course new, but here's the kicker to your pointless argument:
Until you see what ATI did on the front end, which won't necessarily be known until the NDA is lifted, how can you say its any more of a reconfiguration than Nvidia? In your own diagram, one would just say GT200 is a GT200 is an expanded G80/G92 (in a similar style to 5800 from 4800). And Fermi had a large change in the shader/arithmetic part of the architecture, and not as much around it - one could say R6xx -> R7xx was the opposite, which was identical shader/arithmetic, major changes on the other stuff (such as TMU/RBEs)
So if you're going to play the "not much of an architecture game" card, one could just as easily point to other aspects of Nvidia and say the exact same thing, which was my point, but one you obviously missed :rolleyes: But that's the thing about unified shader architecture, you'll rarely see every aspect overhauled as we saw with G7x->G80 and R5xx->R600
AMDs David Hoff have said the following
http://www.techradar.com/news/comput...s&attr=newsall
"Hoff was also happy to speak about it's upcoming new range of DirectX 11 graphics cards. "It's certainly more than changing a sticker," he said with a grin. "I wouldn't say it's an absolute, complete from the ground up new architecture .It's a nice, different architecture."
Yes they changed the Front End and they have every right to call it 6000 if they want to but that doesn’t change the fact that 6000 is not a new architecture.
Here are some figures from some aussies:

The card in the quoted system in the second link is the 6870. Hopefully you guys can view it :up:
This thread is full of pointless discussion...
why argue if its a complete change or a small change when we already know it wont be a direct rename?
why argue if the naming is misleading when we know its priced for mainstream and any small confusion will only last one month till cayman?
let me throw in a new topic:
will you be able to crossfire barts with cypress if you wanted?
(if so, that is what i recomend for Dark-Energy)
Radeon HD 6870 is Twice Faster than GeForce GTX 460 in MSI Kombustor

GTX 460
http://img530.imageshack.us/img530/9...tx460score.jpg
:shocked::shocked::shocked:
To be honest,CPUs are clocked at different frequencies(QC Deneb @ 4Ghz,QC Penryn @ 3Ghz),but that is not nearly enough to offset the more than 2x performance difference between 460 and 6870. Amazing what a GPU like Barts can pull.
edit:
ethomaz ,C2 X9650 is a QC as far as I know.
Regarding MSI Kombustor benchs, how much 58xx got for that bench? Seems architecture changes are not that tiny even it is tiny bench :D
Mine...
Stock cpu and 775/1125 gpu
http://img229.imageshack.us/img229/4715/komph.jpg
Yeah, right so it's irelevant, 5850 is also twice as GTX 460 in Msi Kombustor...
its based on Furmark, which has since the 2900s, been doing very well with the simple shaders on ATI hardware.
i still remember the whole fiasco where ATI cards would overheat and shut down, or throttle. and everyone is freaking out, yet none of them ever cared to realize their fps was also 50-100% faster than the competitions.
just did a test on my 4850, got 220fps average, however i only had opengl 2 or 3 to choose from, no d3d10:shrug:
http://www.geeks3d.com/20100810/gpu-...1-3-available/ here you go. same as on ss, 1.1.3 version
http://img109.imageshack.us/img109/9810/9436.png
oddly things didnt run at that resolution. the text was a bit blurry and i had a popup from my monitor saying i wasnt running 1080p, not sure how much that affects things
but basically ATI cards do great, and consume massive amounts of heat in these fuzzy programs
now i see that is not good bench to judge
even my 4850 beats 460GTX :D
Some more FUD info (looks accurate): link
Quote:
We are still getting some last minute details about Barts PRO and XT. This time we can tell you that Barts PRO and XT parts feature a 255mm2 die size. This is quite good as Radeon HD 5850 and 5870 had 334mm2 size. The chip is almost 30 percent smaller and the new one consumes up to 151W in the XT version, which is less than the Radeon HD 5850 series. Radeon HD 5850 had 2.15 billion transistors while the Radeon HD 6850 and 6870 have 1.8 billion.
Radeon HD 6870 has a total memory bandwidth of 134.4 GB/s, 900 million polygon/ sec geometry throughput and 14 SIMD engines, four less than Radeon HD 5850. the total number of stream processors is 1120, while HD 5850 has 1440, the 6870 has 56 texture units, 128 Z/stencil ROPs and 32 color ROPs.
AMD claims that with a good CPU it scores 7730 in 3Dmark Vantage Extreme, most likely with a six core top notch CPU. The maximal board power is as we previously reported 151W while the idle power stays at 19W. The idle power is better than Radeon 5850's 27W while the maximal board power remains the same.
Launch day is as Friday the 22nd, as we've already said a few times. All this comes from the mouth of Eric Demers, CTO of graphics group and a very nice chap. Of course he didn't tell us this directly, but these specs is what he showed to AMD's tame press.
this rename arguing is completely pointless; when did we see completely new architectures?
ATI:
9800-X800 refresh
X1k series completely new
HD2xxx new shader part; same memory controller (2x wider)
HD3xxx tweaked shader part; different mem controller
Hd4xxx same shader, tweaked mem, bigger = refresh
HD5xxx tweaked shader (DX11; tesselation); same MC, same front end
HD6xxx tweaked shader / new shader (barts/cayman); unknown MC; new frontend
so when was the last time we saw a completely new architecture?
i think that was the x1xxx....
going by the logic of some people in here we'd call the next card X1999 XTXXXX edition v2....
if there is a major perf improvement or power efficiency improvement you can give it a new name; which has been the case since the 7xxx days with ati....
nvidia on the other hand had some very inconsistent naming in the last few years....
this post shows why Nvidia has large dies.
from G80-GT200 you gain 33% larger SIMD array (I think) The node shrink only help so much in design
and from GT200 to GF100 you gain an even larger SIMD array.
They have only kept adding to the SIMD arrays and have not taken anything out to shrink it's design size.
ATI here did this
3870-4870 did away with Ring bus and added more UDV stuff
4870-5870 did away with crossbar in there and add more powerfull tesseltion unit
5870- 6870 did away with 5:1 simd and went to 4:1 and add even more powerful tessellation unit lastly dual Rasterzisted.
(this excludes any AA and AF changes)
Yep I agree with you , and think bout it logically why would the design a new arch over and over again when there is plenty of improvement and tweaks to be had with the old arch , its not like this is the exact same thing, its the old arch with stuff readjusted, its been tweaked it uses less to do more and that is what progress is all about. I mean nvidia arent going to redo fermi from the ground up, they are going to tweak it , redo bits to deal with the issues, but they are going to call next set 5xx.
This whole arch-u-ment is pointless, it doesn't have to be a complete redesign, to be new.
they tweak and make small improvements and offer a better price/performance ratio.
if u run a company, its kinda hard to justify a Fermi approach especially since amd still runs red in the books.
however I do expect the 6970 be a little extra than last gens 5870.
I will be surprised if you can qualitatively tell the difference between 6870 and 5870.
a judge of this will be the normally ridiculous (but well intentioned) hardocp benchmarking system.
if hardocp thinks there isn't enough difference to warrant different visual settings, they will benchmark both cards at the same settings.

sorry if they were posted earlier
I just called a large local computer store chain in the area to ask when they will have stock of the 6800 series and this is the reply I got: "Herpity herp herp derp... derp, maybe a month or two? We dunno, lol."
Absolutely useless, not one store can confirm when they will have stock even though the release is supposedly this Friday.
Edit, nevermind, found some comparison:
http://benchmarkreviews.com/index.ph...1&limitstart=7
Taking into consideration 1080 vs 1200 vertical pixels and CPU, looks to be right between 5850 and 5870.
^^
not every game.. sometimes needs more sometimes needs less
scored higher with my gtx 470 and the pc in sign... but i guess that the 68xx card will consume a lot less power, not that i care about that...
so as expected; 6850 @ gtx 460 level and 6870 between 5850 and 5870; pretty impressive considering the tiny die size and if prized at 200 / 250$ they'll give the 460 a run for its money!
only 2 way crossfire? not good.
I don't see why you need to use 4 cards
After all, these are mid-range cards, not even high end. It's a shame they had to call it the 68xx series, and now I can totally see this causing confusion with all the tech illiterates (not saying you are, btw). I suppose Cayman will have 4 way for obvious reasons. Juniper did as well, but, I can't really see this being of any use anyway unless for the sole purpose of benching and/or record breaking, but then, Cayman would suite that area much better?
Meh, I don't really think it's that big of a deal.
Why?
Wait for 6950/70 if you want more power than 6870 x-fire....
Edit: Or non reference pcb...
GTX 460 1gb, 800/4000, i'm not to impressed by 6870...
http://forum.lab501.ro/attachment.ph...9&d=1287606971
Didn't read all of posts, are there any info on OC room on 6850 or 70 ?
6850 will be my pick, should be good upgrade from 8800 GT :p:
Phenom x4 and 6850 should serve me some time :)
Don't get so worked up over it. We don't know if it really is 4d or 5d. But if it is 5d then it is probably an evolution of the cypress core. If it is 4d then it is probably a whole new architecture. I'm not saying either is the case.
Edit:
If a reworked cypress is AMD's backup plan to the canceled 32nm, I can't really blame them for being conservative. It's a lot better then Nvidia's "we don't need a backup plan".
Hmm.. Looking forward to a nice 6870 vs 450's in SLI comparo.
Sigh...after following this thread for so long and seeing these preview benchmarks up, I think they should've called the cards the 6840 and the 6860...I know they don't use those numbers typically, but it seems more suited as the performance is slightly below the 5850 and the 5870.
Right, but a 5830 just has some of the cores disabled, it started life as a potential cypress chip. They could, however, make a chip that only includes 1120 shaders from the start, based on an upgraded/modified cypress architecture.
Most of the rumors so far pointed to a 4d design and that's what I had hoped for. But the early numbers and AMD slides have given me pause. Perhaps we won't get the 4d arch until Cayman or even 28nm. I suppose we will find out soon enough.
That's what I mean, Barts was designed from the get-go to be smaller. One could just as easily call it a re-designed compact-er Cypress, but one could also call it a beefed up Juniper mated to a 256-bit interface.
I think given that AMD found out about the cancellation of 32nm relatively late in the game, they decided they needed a product to fill the gap between old 40nm products and when 28nm is ready, and hence NI is going to be a half-way architecture. That is, Evergreen 4+1 shaders but the new front endQuote:

Actually that makes Cayman more interesting, because even if it isnt 4D, the fact that Cypress is (allegedly) very ineffcient despite all its functional units (its literally 2x Juniper on a single die, yet 2 x Juniper in CF beats it often), that the front-end changes might affect Cayman a lot more
Curious why the bottom box is cut off on the right side:confused:
Anyways....
5850 725/1000, 10.4 Driver, Crossfire Disabled

5850 900/1050, 10.4 Driver, Crossfire Disabled
http://i52.tinypic.com/5ydi6s.jpg
I recall they made some driver improvements for 2.1 Heaven after 10.4 and being as close as these are and the bottom box being chopped I'd like to think someone just benched a 5850 at 6870 clocks.
Otherwise coming from $250 5850's a 6870 for the same price is:down:
The cut off box pretty much says its been photoshopped
Whether its relevant photoshopping or not, it doesn't say, but it doesn't help its credibility
I see what you are saying. Maybe my choice of words wasn't the best. I guess calling it a scaled up juniper or cut down cypress depends partially on if you are trying to convey a negative or positive impression. "Modified Evergreen" might be a more neutral way of putting it.
I never believed the rumors about a frankenstein between cypress and NI. Making parts of two separate architectures work together would be an incredible amount of work and has so many potential pitfalls that it doesn't seem like a sound backup plan, IMO. Now they may have back-ported some of the lessons learned in developing NI to a modified Evergreen, but I doubt it would be the full NI front end.Quote:

any shots of the heatsink yet?
I dont think that bench was legit for one. Notice the same clocks and ~equal scores.
If it is a legit bench then this only shows clock for clock they are equal in this bench.
Secondly I dont feel we will see much high overclocking head room on the 68xx.
I expect the same ~1000-1080mhz core limit as 58xx's but we should find out for sure in the next few hours :D:up:
EDIT: I did post a default 5850 run in the first SS ;)
but i think that 5850 OC potential is significantly higher considering the very low baseclock; 5850s in ref design run up to 1ghz on the core; i think that we can't expect more than 1.1ghz from barts -> they'll end up with equal performance when overclocked
i'll stick to my 5850; it's been doing its job for a year now and i still can't see a proper replacement, never had a graphics card hold out that long :D
I thought the new front end for the hd6xxx was going to give the architecture more efficiency (clock for clock)
well it gives it.
900 Mhz 5850 (1440 shaders) = 900 Mhz Bart XT, with 1120 shaders. So i think the efficiency is there.
Those HD68X0 parts deserve HD67X0 branding, nothing more, AMD marketing failed ...
Could you update your driver and rerun both at default and 900MHz ?
