ATI RV770 'On Par' With Expectations

With the launch of the GeForce 9 series getting closer and closer, AMD is hard pressed to find something to keep themselves competitive. While the RV670 and R680 are regaining some much needed market share, they will both pale when the GeForce 9 series is released to the public. Thankfully, AMD is not going down without a fight. About the same time as the GeForce 9 series is released, AMD is releasing a little something called the RV770. At this point, it appears that the RV770 is about 50% faster than the current HD3870, which is certainly respectable. How this compares to the GeForce 9 series is still a mystery. The release of CrossFire X technology ought to really help benchmark numbers, assuming AMD can make buying four AMD GPUs cost about as much as two from NVIDIA.

Hmm... 'only' 50% faster than a 3870, that roughly puts it at the levels of a 8800 Ultra...

If true, I'm not impressed. It needs to be closer to 100% faster than the 3870 to seriously challenge the GF9 series IMO.

[realsmasher]

which gf9 ?
true gf 9 ?
gx2 gf9 ?

'only' 50% faster than a 3870, that roughly puts it at the levels of a 8800 Ultra

880ultra is only like 25-35% faster, but well 50% is really not much...

[GoThr3k]

RV means mainstream segment, like 3850/3870

so 50% faster isnt that bad

RV770 its not High end , that will be the R700

I like the sound of this but I want to see actual chips before congratulating AMD.

In that case it's excellent news if true. :up:

[Morais]

Yeah good news...Any dates to launch?

[ownage]

In that case it's excellent news if true. :up:

Its true. :D

RV770 means Radeon Value 770. The R700 will be high-end.

[mascaras]

Yeah good news...Any dates to launch?

last rumors :



scheduled for late Q2 if not early Q3.

[RPGWiZaRD]

Sounds good for a mainstream version. I think we can expect some huge performance boost once GF9 series & R700 arrives.

[Shintai]

I have a feeling RV770 is "highend". Just like RV670.

AMD dont seem to wish to focus on highend GPUs. And its easy to understand why.

[v_rr]

RV770 is Value! Not high-end. Never high-end....
ATI can put tow of these in one PCB like R680 and makke it high-end? Yes.

50% more performance then HD 3870 is a tremendous boost.

So its still RV770. Having 2 RV670 chips on a board with crossfire and 2xmemory dont make it R680. Thats just fancy marketing. Then I could just buy 2 or 3 midrange cards and proclaim superiour performance. If Crossfire and SLi always worked 100% and you had all features and no problems or loss like minimum FPS etc. Then sure. But we are relatively speaking lightyears from that.

So again, there is no highend.

Nvidia do the same with 9800GX2. So deal with it, its high-end and lots of people buy them. It´s single card....
Also I didn´t say that is that the future. Only say that it is one of the chances.

[Rob94hawk]

AMD just needs to stop dicking around a create a vid card that just kicks ass and takes names. But it's probably not going to happen since they cant do it with their cpu's anymore.

Not based on Fuad, I received the information before he wrote that. I saw his post before I wrote mine, and I hesitated both once and twice before posting, but I wanted to play down the significance of 50% faster. 50% is exactly what the chip should be doing, it's not a surprising figure. Somehow, Fuad makes it sound like it's something awesome, when it's really not. It's just what it's suppose to do.
It's not the first time I've received information that's very close to what Fuad has been writing, but it's not like I want to stop the source from sending the info.

Might as well call it AMD since AMD does own ATi.

[Zytek_Fan]

50% faster isn't bad for a mid-end product.

I'd hope AMD gets back into the high-end segment with R700 since it's been planned for a while.

[horn_]

So when is this thing getting released?

[adamsleath]

another cheap performance card
:woot:
keep them coming i say :)
Ive heard rumour June/July...

Latest is sometime in June, for RV770.
Haven't heard anything about R700 other then the old timeframe of late Q2/Q3.

So you are still hoping that R700 is just CF?
Glad you are always so optimistic.

Around Computex is a reasonable target for release :yepp: :D

[adamsleath]

yeah but most likely after computex.

[Rob94hawk]

ati does gpu thing not amd

AMD owns ATI.

/class dismissed

[eric66]

AMD owns ATI.

/class dismissed

so what they don't make gpus ati makes it every graphic card is named ati radeon :up: i hope it continues that way :D

[BrowncoatGR]

There is no ATi anymore. Its just an AMD owned brand that they keep using for marketing reasons. New GPUs are designed by AMDs Graphics devision

[Frank M]

Around Computex is a reasonable target for release :yepp: :D

Computex and other large trade fairs are traditionally more about product
announcements and some working techdemos of what's ahead. For their
sake I hope they release it earlier. And for our sake, too :D But given that
9600GT is not far away, and 3850&3870 are just slightly improved die-
shrinks of R600, they are under some pressure to release something new
and more powerful to remain competitive.

[Swatrecon_]

so what they don't make gpus ati makes it every graphic card is named ati radeon :up: i hope it continues that way :D

Wow.....

You've been corrected twice now and you still don't get it. ATi = AMD. They kept the brand names ATi and Radeon to avoid consumer confusion. It's not that hard to conceive. AMD makes Video Cards and Processors. They have separate divisions for each.

[eric66]

AMDs Graphics devision = old ati am i right ? i mean did amd has its own graphic devision before ati ?

[GMX]

just drop it ffs.

[freeloader]

AMD should just give up on the high end GPU's. Let Nvidia have the 1 to 2% of that marketshare and concentrate on mid and low end cards, where the real money is.

[GMX]

well if u do that nvidia can spin it so wonderfully, infact they would love it. How many of that 98-99% would buy a nvidia card now based on the fact the new high end ultra is unstoppable (in actual fact no proper competition)

[Zytek_Fan]

The high end is what sets the tone for the mid and low end segments.

[HKPolice]

RV770 = Chip name
R700 = 2x RV770 chips on the same PCB, connected via a fast interconnect (not PCIe bridge or switch) and will appear as a single GPU.

If you CF 2x RV770 cards, it will be slower than R700 unless ATi is able to integrate the interconnect over a bridge connector which I have doubts about.

R700 is supposed to be dual core (2 cores on one package), so it'd be interesting how they would implement 2 x RV770 cores on one die...

Nope. 2 separate BGA packages via a fast interconnect on the same PCB.

It's cheaper to mass produce a single package (RV770) than to redesign a custom dual core package for a niche low volume high end product.

[madcho]

R700 = 2*RV770 on the same chip, it's an MCM not a crossfire. The OS'll see it as one GPU.

One memory bank ...

If RV770 is 50% faster, nvidia cannot do a better GFX card with the 9 series.

R700 will be the monster of 2008 :D

I will be precisely as R680 is today.

[hollo]

yeah what these guys ^ said, r700 performance part is made up of two smaller mainstream GPUs, but not just dumbly crossfired. if the rv770 is 50% faster than 3870 then r700 is going to be a fkn beast!!!

AMD should just give up on the high end GPU's. Let Nvidia have the 1 to 2% of that marketshare and concentrate on mid and low end cards, where the real money is.

that would be suicidal. high end cards are essentially tech-demos - they are where the company is heading. and in a high growth area like consumer electronics they are essential products, not to mention being the best marketing money can buy.

I find it amusing how much things you always "know" Shintai while I have a feeling you don't have much connections in the HW business, if any at all.

You still owe $100 to some guys from the last bet you made. Have to admit that it's hard to prove anything until NDA is over though. Will you honour that bet?

[freeloader]

The high end is what sets the tone for the mid and low end segments.

Joe Blow who's buying a PC from Wal Mart/Best Buy, etc... doesn't know the difference. As long as you can compete in the mid range segment, you'll do fine.

I owe anyone anything? The lasted rumour news puts it back to L2. I think you try and skin the bear before you shoot it!

I dont pretend I always know things. But there is alot more reason and logic to be added. Also its easy to see your stand with your avatar :rolleyes:

They would also have to make 2 chip designs. One with massive I/O ports and one without not to lose valuable money on singlecards with wasted diespace. Plus they had to invent the 100-200GB/sec I/O system aswell. I´m sure IBM and Intel would be jealous.

And with the super parallel nature of GPUs plus their natural design of not working well in more than 1 (Not as iN SLi/CF), it would simply be CHEAPER and more EFFICIENT to make a singledie big GPU.

[saaya]

well its hard to read anything from theese numbers since we dont know if rv770 perf is referring to a single gpu card or a dual gpu card.

depending on if its UP TO 50% faster or 50% faster on average, and if they compared dual gpu to single gpu or dualgpu to dualgpu id say this sounds like rv770 is ok to good. but nothing spectacular...

Because yields on a 1 or 2 billion transistor processor where most of the transistors won't be going into cache is going to acceptable.

So, any vague guesses on how much the RV770 will cost in UK on launch?

The fact that I don't like Nvidia's "the way it's meant to be played" program doesn't mean I'm an ATI fan. I've owned more Nvidia cards than ATI cards in my life and currently I have a 8800GT (like you can see in my sig) and I actually have another ES card from Nvidia that I can't yet disclose :p:

They have made a 1024bit ringbus MC before with impressive performance. They may be able to use their experience from designing this MC in this new project to get pretty spectacular results. I/O doesn't need so many transistors like shader units and ROPs. The 1024bit ringbus controller was actually tiny compared to the other stuff on the R600 GPU. Yields of good functioning transistors/transistors on the complex MC was most likely lower than those on the shader units and ROPs for example. I think these two facts might make it profitable to have just one GPU design which has stuff deactivated on single die cards.
And with the super parallel nature of GPUs plus their natural design of not working well in more than 1 (Not as iN SLi/CF), it would simply be CHEAPER and more EFFICIENT to make a singledie big GPU.
You pressume too much things. It seems like you have even more data than ATI engineers. Yields and stuff like that are very very hard to make a prediction about, even for the design team.

[awdrifter]

50% faster is not bad, assuming ATI can actually deliver it on time. And from what we're seeing right now, the R700 will probably just be 2xR770 chip like the HD3870x2.

[ANP !!!]

Yea, not bad at all after all we are comparing a Mid-range card with the current gen high end card. :up:.

massive ammount of bandwidth doesn't equal automatically to a massive ammount of I/O operations.

[saaya]

after thinking about this some it sounds like this is the perf of a single rv770 gpu compared to rv670. if thats the case then this is pretty good as we would get a mainstream card costing less than the 3870x2 and beeing even faster!

and a r700 beeing 2 rv770 gpus would mean 3870x2+50% which is really fast.
and it might be more than 50% faster than rv670 on a dual card since it should be optimized for xfire...

the really interesting question will be if it will share the vram and if yes how.
and how efficiently... if it shares vram and does so efficiently this would mean that a dual rv770 card would be even cheaper compared to a single rv770 card than the 3870x2 is compared to the 3870!

the 3870x2 is around 2x the price of a 3870, and ati could even go lower with the price and still make profits. if rv770 shares the vram id say a dual card would only cost 50-75% more than a single rv770 card.

rv770 should launch at around 299$ and a dual card will be 399-499 depending on price/perf of other cards on the market.
this is pure speculation :D

[Dimitriman]

So i can believe the hype??

[Zytek_Fan]

you guys remember the speculation of the r600s? just don't get your hopes up guys...

R600 had major power consumption and leakage problems.

[Craftyman.]

I believe this architecture is heavily based on on the architecture or both R600 and RV670 so I wouldn't discount the hype yet monkeywoman and like the poster above said R600 had leakage problems.

[Zytek_Fan]

So i can believe the hype??

The hype is that R700 is going to be a monster, so for the time being you can believe the hype.

I'm sure benchies will start leaking in the coming months :yepp:

[hollo]

i take back what i said about r700 "going to be a fkn beast" if it's just gonna be a rv770 version of the 3870x2. i thought they might do something more complex, something reminiscient of a MCM dual-core CPU with shared memory

:shrug: :confused:

[cegras]

I don't see what's with everyone going "INTEL'S METHOD IS THE BEST, DO IT MCM YEAAAAAH."

No one here even considers what the meaning of yield is.

[hollo]

intel using MCM for pentium d/core2quad is totally unrelated, it's just that if r700 is made of multiple rv770s it'll either be-
1) crossfire with duplicated memory (old news, boring)
2) shared memory, a little like an MCM dual/quad-core CPU (which would be a very interesting jump in GPU technology)

The rumor is the second choice is what they are shooting for, but that was before the AMD acquisition, so who knows how much they have cut/changed if any at all

[Zytek_Fan]

Supposed to be 2 cores on 1 package with shared memory, which could happen, although it could have some minor problems...

[mascaras]

[FUD] RV770 and R700 to use GDDR5

The next generation

ATI's new flagship performance and high end chips will have the ability to use GDDR5 memory. This is the next big thing that ATI plans to embrace.


It looks that GDDR4 didn't really hit off well, as it doesn’t brings a lot of advantages over GDDR3, but GDDR5 promises some crazy frequencies all the way up to 2.5GHz / 5GHz effectively, which is more than two times faster with what you can achieve today with GDDR4.

This mean that the new memory will have more bandwidth and this is something that graphic card always enjoys.

At this time, we are not aware that GT200 has GDDR5 support.

[Craftyman.]

All I can say is... :shocked:

[Craftyman.]

Is it me or does just the acronym GDDR5 look like something that can't possibly exist :D. It would be really nice to have huge memory bandwidth for higher levels
of antialiasing and other memory bandwidth intensive features :up:

[Origin_Unknown]

5ghz ram :o

whats the release period on these? (r700)

[Nedjo]

Fuad greatly overestimates GDDR5...
or misinterpreted... highest speed GDDR4 is kicking 2.4-2.5 GHz now (real 1200-1250 MHz), so 2.6+ GHz (1300+ MHz) for GDDR5 would be natural progression...

GDDR5 can touch 6ghz, has better power savings than GDDR4 and offers 2-3x the performance.
While we may not see these results with the ICs on the cards we buy, that doesn't mean they are lying.

or misinterpreted... highest speed GDDR4 is kicking 2.4-2.5 GHz now (real 1200-1250 MHz), so 2.6+ GHz (1300+ MHz) for GDDR5 would be natural progression...
See above.

Its true. :D

RV770 means Radeon Value 770. The R700 will be high-end.

a value card will be better then my suppose mid end 3870..

this is my at times i ask myself why i keep upgrading

[hollo]

no, the hd3870 is rv670, where v = value... it is also a value card :p
r600 and r700 are meant to be the non-value cards-

Show me the 5Ghz GDDR5 out there. Or tell me why GDDR5 will scale 100% or so. Or just even give me a proff on any company even estimate 2.5/5Ghz.

GRRD5 seems very fast - but I think it's doable, the huge performance gap between GDDR4 and GDDR5 is due to the fact GDDR4 sucks, it didn't offer too much of improvement over GDDR3. If 3 to 4 was as good as 2 to 3 we would have a much faster 4 and a 5 that is not that much further in performance.

there is faster gddr4, check samsungs product sheets, but its extremely expensive and has low yields i guess

I wouldn't trust that list that much. I've seen them put pretty much anything rumor-based in there.

On the GDDR5-side of things ... RV770 seems to have the support, but I seriously doubt it will use it until far later.

I can tell you this for certain: ATI is focusing on performance/penny. Raw, extreme performance is out. If you want better performance; get two cards/cores. ATI has tremendous faith in CrossFire, and that's where they will put most of their effort.

Considering this, GDDR5 seems like a very poor choice. GDDR3 still performing adequately and is most of all cheap. GDDR4 is getting there, but GDDR3 is so cheap and relatively fast that I wouldn't be surprised if we see plenty of RV770-based cards with GDDR3 as well. The cards we'll see at CES will most likely be GDDR4, but other than that I sense that it's much more likely that we'll see GDDR3 than GDDR5 paired with RV770.

There won't be any more extreme high-end single core chips from ATI. It's not the future for ATI.

Yeah, kinda sad though, because that means that we won't be seeing any competition to nvidia's gt200 except for the dual rv770 card which may or may not scale well depending on drivers and how games are coded. I'm just afraid that nvidia will start charging the prices they did for the 8800ultra at launch again ($800+), and also what happens if nvidia's price:performance ends up being better due to stronger performance for just a slightly higher price as it was with the 3870 vs 8800gt situation (not to mention the gt seems to be cheaper now that prices have balanced)

[zerazax]

It all depends on how they handle multi-core/chip. Whether its like the 3870X2 where it's basically internal CrossFire or whether it has a MCM and the OS sees it as just one giant GPU and runs it as thus

[whocaresbg]

RV770 clocks above 1GHz, launch in May :

RV770 clocks will be above 1GHz, much higher than RV670. The memory used are GDDR5. The yield rate is as high as 71%. The GPU revision is A11 and this will be the revision on the retail cards. The recently leaked RV7xx specs are all bull:banana::banana::banana::banana:. RV770 architecture is similar to RV670 but further enhanced.

Glad to hear that!

Over 1GHz is very nice, but I hope they also added some texturing power.
Any demos at Cebit?

[Monkeywoman]

The lowest end one is codenamed RV710 followed by RV730 and RV740. The RV770 is the ultimate replacement for RV670, the hearth of Radeon 3870 cards, while the R700XT will consist of two RV770. This is how the line up looks like and you won’t see these chips before summer time if not even later. so sadly no cebit :(

So is the guy who just said May misreading the source he linked to (i can't open the page for some reason), or are you getting this info from somewhere else?

[Monkeywoman]

naa man, thats form fudzilla. the stuff they get is from close people to the companies and stuff, they might be wrong but most of the time they are right.

At Computex maybe :rolleyes: .

Iirc it was mentioned in an interview that they will adjust the shader/TU/ROP ratio and bring back hardware AA. I already started saving up some money :D

[whocaresbg]

They should use the old and tested ALU:TMU:ROP 3:1:1 ratio .

[flippin_waffles]

My guess is that Fudzilla has this right, and what chiphell is refering to is actually the new spin of RV670 or A12. Fuad mentions that they expect these to release around the same time that chiphell is saying RV770 is going to launch. So, I bet the 1000mhz+ chips are A12 RV670's. Remember that R600 and R700 had different design cycles, with different teams even, so I find it hard to believe that ATI would have designated an entire team just for a clock speed increase.

+ agree with that it looks like another revision of rv670 everyone expected it to oc like hell but it didn't happen there was 860 mhz limit probably they solved it

If you're referring to the 862 core limit of the 3870, that was a bios issue and was solved quite a while ago.
