ATi Mobility HD 6000 series Roadmap

Who knows when Mobility 6000 will show up in notebooks, as an available to purchase. Could be December at the earliest, unless manufacturers are just sitting on machines until ATI formally announces it.

 

Now the rumors are saying Barts will be the desktop HD6800 cards.

Barts retail model is indeed a HD6800 - Chiphell

Casts doubt on the legitimacy of the latest leaked slide.

 

Sounds like a stupid move. If the 6770 is just above a 5850, why name it 6850 when you know a LOT of people are gonna cry us a river about how the 6000 series isn't that much of an improvement and blah.

 

Maybe they have more powerful cards which will be released at a later date.

 

That's true, but the heat and power consumption will also last 3-5 years.
Let's say I'm more in the 5830M range, power @ 25 - 30W

 

I thought we already killed the rumor that AMD will change the names for the 6000 series in such a way that HD 6800 series will be mid-end while HD 6900 will be what was HD 5800 before. In any case, it does not matter, Barts will be mid range whatever its name.

More interestingly it seems like Nvidia is already working on something to counter the 6000 series and it seems to be something other than a fully enabled GF104.

 

But they already made their entire fermi mobile line up. Which means they can add a GTX485M and that's about it.

They stille have enormous TDP problems.
Core clocks are low, and memory too.
625mhz on a GTX460M (so based on G104) then try to compensate it with larger PCB memory bus (192 bit) but it also consumes power and it makes it more complex to produce.

 

Those who own high-end gaming laptops pay for their power consumption the hard way, the differences between the 480M and 5870m may be significant, but owners of either model are paying through the nose anyway in electricity bills to maintain performance.

I have a relative who owns a 5830m but the needs differ from mine. I'll likely end up going for a 5870m CF solution and its attendant electricity bills just because I value performance.

 

That's what we thought when AMD annouced they would release the 6000 series without a whole new architecture and it seems that it still is going to kick . Nvidia could rework fermi in a similar way. E.g. scale down the tesselation parts for mid-range cards (as they are to weak to play games in high details and high ressolution with tesselation anyway) and/or remove some of the L2 cache and stuff. They could improve the performance per watt ratio considerably if they would split up the architectures for each field and focus on gaming with the GeForce series and drop all those parts that only make sense for professional use.

 

i can't find it back but i recal reading that amd was to release mid range first and maybe wait for 28 nm for the high perf so what we are loooking at is very likely a mid range card

 

Rumors can only be killed by solid facts released by AMD, and we haven't seen any of those released yet.

"The people in the know" (I'm not one) might be getting fed bogus facts by AMD just to throw off leaks.

Not for notebooks.

GF110 makes alias Geforce GTX 485 or GTX 490, the round - PC Games Hardware

 

lol wuttt this is all but clear how ever it really look kick *(*

 

What's unclear? It's already pretty much accepted that Nvidia has a 384 Core GF104 available to release as a replacement for GTX 470, and where they need to release something to compete is against AMD's Cayman and Antilles in the desktop market.

GF100 won't cut it, so Nvidia will have to use two GF104...either somehow fused together as a massive GF110 die, or in your standard dual GPU on a single PCB card...or both.

 

i fear the price of such a thing LOL and even more fear some is if it's a single die imagine the price of the MARS III based of this


well the article is google translated so that what i mean by all but clear

 

Radeon HD 6000 debut reportedly postponed - The Tech Report

Might be delayed...

 

Update: Actually no, it's on track - Fudzilla

 

amd is playin it nice with thier 3 launches and waiting for 28nm for the 6800 serie so they can slam back nvidia's counter offering atemps in hell

 

28nm is a year off, if not longer, for both companies.

The cancellation of 32nm for GPUs threw off everybody but if enough of the rumors turn out to be true then AMD has turned a problem into a golden opportunity to trump Nvidia.

We'll find out for sure in a couple of weeks.

 

well 28 is for Q1 2011 so i think it still make sense

 

28nm is still far, far away ...

 

2011, 2nd half, most likely

 

AMD Radeon™ HD 6800 Series GPU Detailed Feature Summary - EXPReview.com

 

Nice find Phinagle. Almost looks as if they improved the stream processors also for better GPGPU power.

 

Woe, woe is the gamer's fate
when in search of power
he self-immolates

 

Yeah, either way all this for PC gaming is just overkill. I played Darksiders today, and it runs incredibly smooth @ 1080p. A high end laptop card can play just about every game at high settings today.

I suppose if you are truly anal and need 8X AA on everything, the next gen GF110 and HD6xxx is a must, but for the average gamer who isn't anal retentive, already the GTX 285M/HD5870M/GTX 460M are overkill.

Frankly if you actually see tessellation at work, amazing textures and creativity looks better. And reality is, game developers have yet to truly tap into the full potential of our current hardware, which is sad, considering how far they have been able to push the consoles...

Looks like Caicos and Cayman to the right and left of Barts. Render and Processing Engine looks like a new architectural feature to handle the change from 5-way to 4-way ALUs.

Caicos (possibly mobile Seymour or Whistler) looks to have 160x4 or 640 shaders with 32 TMU and 16 ROP while Cayman looks like it's got 480x4 or 1920 shaders with 96 TMU and 48 ROP.

Based on the previously leaked slide that said Bart XT was a 1280 shader part the Cayman part might also be the XT version and therefore could have a cut down PRO version to go along with it.

EDIT: Looking back at the leaked names from the drivers only a Caicos PRO is listed so there may be only one derivative.

 

If you play on a larger screen, you will want AA.

 

Look at this, guys!

If that's true and Bart XT beats the HD 5870, while PRO beats the 5850, than we might expect the M6870 to be ~HD5850 @ stock may even kick the HD 5870 when OC'ed!
This is probably too optimistic to even think about , but ...

 

I don't get it. Barts Pro & XT were supposed to replace 5750/5770 (Juniper) from what had been said and it says it will replace Cypress (5850/5870). So what would replace Juniper at 150-200€ price point ?

 

This would be the biggest performance leap since Nvidia's jump from the 7000 series to the 8000 series. But somehow I doubt it, I just think there is catch... more power consumption ... or maybe wrong info, who knows.

 

Turks was always the GPU most likely positioned to replace Juniper....though at 640 shaders Caicos could probably do it too.

Right now there's still conflicting rumors going around (some likely seeded by AMD itself to throw off leaks) on whether Barts will cover the HD6700 or HD6800 parts for desktops, but for notebook users what AMD calls the desktop model isn't as important as what the specs and power usage of the GPU will end up being.

 

If the leaked benches are accurate, I'd say the horsepower is there. It's just what TDP cost is it at.

 

we need a better midrange 6xxx series card. my 5730 chuggs sometimes maybe something 600sp or around there.

 

Yeah I'm remaining cautiously optimistic.

I just wish AMD would release a Mobility 6970, a super high-end card which uses 100W. Then they could still release Mobility 6800 and 6700, with more modest power consumption.

That would be freaking epic.

Don't worry, that's a given.

Mob. 6700 will definitely be in the 640 shader range, likely with GDDR5.

 

A 640 SPU part could be the "low-end" discrete part the way IGPs are looking. :wink:

 

Radeon HD de la série 6000 : vers une "puissance doublée" dès novembre ?

i don,t recal if it was entirely posted here but look at this anyway

 

Wow if true. Look at the specs on the 6750, in comparison to the 5770. The Mobility 6870 will be epic.

The 114W falls in line with what ATI was able to accomplish with the 108W 5770.

 

Those have been posted.

There hasn't been any new rumors for about a week now and it's looks like AMD maybe rooted out all their leaks by seeding them with differing NDA info. The only current back and forth between speculators is whether or not Barts is the 6700 or 6800 series. Some leaked material says one thing, others say something else.

My personal guess is if Barts isn't the 6700 series then Barts PRO is the desktop HD6830 and Barts XT is the HD6850. If the rumors of GTX 460 < Barts PRO < HD5850 < Barts XT < HD5870 are close to true that would put the HD6830 and HD6850 at a 12-25% gain in DX9/DX10.1 benchmarks. While that's not very impressive at first glance AMD can hype DX11 gains, along with performance/watt gains that are actually more like a 20-30% over the last generation and, because of what will probably be a smaller die, a similar gain in performance/mm....which should translate to better performance/$$.

Cayman could then be the desktop HD6870 and HD6890 (or HD6860 & HD6870) and should offer performance to compete against a 384 core GF104 and whatever a GF110 might be. Turks could then fill in the HD6700 parts when it comes out (might be later), and Caicos could cover models HD6600 or lower. Antilles will be dual Cayman cards.

Of course I used the same system to pick those model numbers that I use to pick my lotto numbers...and well I ain't a millionaire. :wink:

Regardless of what AMD calls Barts for the desktop market, if the top end mobile parts are based on a Barts PRO or XT, with the rumored specs, then notebooks would be getting a much better performance bump out of those parts than desktops....since mobile cards would be going from an HD5770 level GPU to an HD68x0 one instead of just an HD5830 to HD68x0.

 

Top 6000M will be based on Barts-pro imho. I fear the TDP of XT is too high requiring too much trimming with frequencies etc. I expect we'll have lower mainstream/enthusiast parts based on Turks too, with GDDR5 hopefully, giving a nice boost to the performance of current 5650/5730 !

 

i just realised there is a 275 mhz gap from the pro to the XT

and that chart just leave me wondering what the 68xx serie will look like cause as it is it seem like the 58xx serie did not ad a fast enough bus so they where datastarving meaning that if the 68xx serie is even faster they will need a largger bus

 

A larger bus isn't required as it's likely AMD will be using 7Gbps GDDR5 chips for Cayman...and faster GDDR5 should also mean memory controller improvements.

 

wouldn't using faster gddr5 blow the power consumsion level in hell?

 

The new 2Gb GDDR5 from Hynix will be on 40nm and operate at a lower voltage so heat and power consumption should be more manageable.

Going the other route and adding a 384-bit memory bus would also significantly increase power consumption....and it'd also increase the GPU's die size making the chip more expensive for AMD to produce. Using faster rated VRAM as a reference would instead likely pass the extra cost onto their board partners.

 

or getting thier partener to install slower vram behind thier back

 

That partner would be hurting themselves more than AMD, or the customer.

Desktop AIBs are constantly tweaking the reference designs even just a little bit to get consumers to buy their version of AMD's GPU over another company's....and those that used slower GDDR5 would lose sales to the AIBs that used faster GDDR5....while AMD would still make the same profit off selling either of those AIB partners a Cayman GPU.

Anyway it's not a concern for notebook users either way, since they're not getting Cayman, and 5Gbps GDDR5 over a 256-bit bus will be plenty of bandwidth for the performance the mobile cards will bring.

 

true but on the mobile market we have a long history of AIB screweing boards

 

AMD Radeon HD 6000 Series in trouble? by VR-Zone.com

 

As long as that doesn't push the Mobility 6800 past Q1, I'm okay with it.

 

Me too,

 

I say fake. What the hell, 40nm process isn't mature by now ? Then the fact that AMD would push Cayman before Barts because of this, show me an ounce of logic behind this because I can't discern one.

It's also discussed here : AMD Radeon HD 6000 Series in trouble! Maybe Charlie can comment on yields? - SemiAccurate Forums

Of course the fact AMD seems to disagree that it'd be nice to hear more from them about 2 weeks before release (theoretically) is disturbing.
