R800 finally shows itself

why does that look a little bit too long?

[trinibwoy]

Apparently that's Hemlock, or Cypress X2. Given that Cypress is supposedly hitting ~P17000 in Vantage, Hemlock should be a beast. No idea how Nvidia is going to compete with this onslaught, it looks like AMD is going to hit them with everything in all price segments.

[jam2k]

Hemlock is supposedly a Crossfire solution but uses SFR, right ?

I wonder if Crossfire profiles / issues will be finally gone ...

[>HyperlogiK<]

Right, and Madoff turned investing into a form of art.

[Spidy]

why does that look a little bit too long?

Its about measure and not about technics. Like in the real world.

[Olivon]

Scoring rumors from that site :

Cypress ~P16xxx - P17xxx - P18xxx
Juniper XT ~P95xx
Redwood ~P46xx

Don't forget the salt but who knows ?

[bill_d]

so Cypress may have 3 different card setups

If nVidia can come up with a counterpart for the fastest AMD card, then rolling the lower cards can easily follow.
It won't be easy though, specially when pricing is one main factor.

So Cypress at worst will be as fast as HD4890 CF... Not bad, not bad

Here is link to my run with Phenom II @3.8GHz+ and HD4870 CF OC 850/1000
P15172 HD4870CF

[Baron_Davis]

I have a feeling Nvidia is going to be having a collective anxiety attack when ATI's new stuff drops in a few weeks...

[Lu(ky]

Great, another leaf blower if this is anything like the 4870x2 was, i wont buy it, loud as hell.

Mmmm last time I checked all cards are leaf blowers using stock card setup in opinion. I run my 4870 x2 at 50% fan on tech station right next to me and it sound low to me..


FYI this sucks I just bought XFX 2 x 4890 cards and eK FB and I find that these new DX11 cards will be out in Sep-Oct And I asked in many many forums when the new DX11 cards will be out they said not tell end of the year Dec-Jan

[cegras]

Uh, no. nvidia's strategy for the GT300 generation is exactly the same as the GT200; big, monolithic die instead of a smaller mainstream one that can scale up and down. You can see how the strategy of 'cut down the flagship chip for lower end parts' worked with the current generation of cards, eh?

When i had my 4870x2, at 40% it was pretty bad, you probably have a noisier room if you think %50 is low.

xfx+ek waterblock=no noise

[FischOderAal]

And I asked in many many forums when the new DX11 cards will be out they said not tell end of the year Dec-Jan

Should've asked in the right forum then *SCNR*

xfx+ek waterblock=no noise

Honestly? I'm tired of watercooling. The HD-4870 at stock was insanely loud, at least for my ears But after I let it downclock automatically as well as adjusted the fan speed it was "acceptable", still not good

[Olivon]

so Cypress may have 3 different card setups

but give a span between P16000 and P18000, which is almost twice the RV840 and already atop of the HD 4870 X2 regions

Here

It's a margin between P16000 and P18000 according to hardware-infos.

That's just because nobody (read nobody but ATI fans) believed the repeated reports that AMD would have a card ready for the Windows 7 launch, I think.

[LordEC911]

That's just because nobody (read nobody but ATI fans) believed the repeated reports that AMD would have a card ready for the Windows 7 launch, I think.

WTF???
Yeah because like 3-4 sources didn't state that they were rolling right along and might have moved the launch up.
Then AMD SHOWED the silicon and even stated in a financial conference call that they would be shipping products this year.

Good one...
IMO, everyone knew they were launching at Windows 7 launch, even the most diehard Nvidia fans. So I don't even have a clue as to where you fall in line.

[zerazax]

I swear every time a new ATI thread becomes a discussion point, the trolls come out of the woodwork to rehash the posts

"Oh it's too <insert complaint about noise, driver, size, heat, etc. that has been a part of every video card generation for the past 10 years>"

Anyways, I think the issue is that there were so few leaks about this card compared to the 4xxx generation where while nothing was concrete for a while, it seemed like the news kept pouring in. This one was a bit harder to believe because no one really talked about it then suddenly AMD claims a launch much sooner than expected...

[Sly Fox]

^^They just can't stand to see the big green giant get smacked upside the head by the red team.

Probably the same people who started bandwagoning the Patriots as soon as they began really dominating.

And then you've got people who always want to root for the underdog. Strange how it seems to work out that way.

Personally I'm interested in the best product at the best price, but I feel like the minority sometimes.

[jaredpace]

So here is what I learned so far (from these guys - hehehe ):
(This is just a collection of rumors circulating the web about rv870 - so for such long post - but i keep adding to it.)


Update: added some updated info from other reports in bold
Radeon "7" Family (Evergreen) is 6 parts:
Trillian = "R800" + either multiple montior or 3-way GPU (could be the 950mhz/4gb R800 or a mcm dual cypress r800 aka 8-way rv830/rv770)
Hemlock = "R800" Dual GPU
Cypress = "RV870" Single GPU
Juniper = "RV840"
Redwood = "RV830"
Cedar = "RV810"
Low end codenames:
Cedar = "RV840"
Juniper = "RV830"
Redwood = "RV810"
Another possibility:
Hemlock, aka r800, aka “5870×2″
Cypress, aka. rv870, aka “5870″
Juniper, aka rv 840, aka “5770″
Redwood, aka rv 830, aka “5670″
Cedar, aka rv 810, aka “5350″ (like how i initially wrote in the first place with "cedar" at the bottom -god this is annoying)
CONFUSION BETWEEN CEDAR/JUNIPER/REDWOOD CODENAMES: They're either going to release a part that scores 12-13k (3/4 cypress) or one that scores 2.2K (1/2 redwood ie 1/8 cypress)... I hope there isn't a part that scores 2200P vantage... well - what is the f*@king point of something so slow in this generation? If they do it like this, it's gonna be like "entry level x 2 = midrange" "midrange x 2 = performance" "performance x 2 = enthus.(rv870)" "enthusiast x 2 = r800" with vantage P scores like "P2200 - P4500 - P9500 - P17000 - P28000" If they do this, there is a huge hole between the 9500P part and the 17000P part! Hello? IMO this reason why Cedar CANT be the rv810 part.
(If cedar is rv840, and sits between cypress & juniper, then it should be score somewhere in the 12k range.
It's score is not given, but it makes sense because cedar would be the part equivalent to the 4850 in the HD4xxx series, and probably fall at a price point somewhere between $349 & $199. Whereas, Juniper and Redwood would be the equivalent of the 4830 and the 4650 respectively. I'm hoping that Redwood is the slowest part. This makes more sense - bah I'm tired...Cedar, call it HD5850, should have specs somewhere between Cypress & Juniper and have a die size of somewhere around ~220mm^2)

Supposedly, the yield over 60 percent, nearly two-thirds of those in 40 nanometer technology made DirectX-11-chip meets the requirements of AMD and is fully operational. That was the first 40-nm graphics chip, the RV740 (Radeon HD 4770), yet very different. And Nvidia also have problems.

For Evergreen, we are required to enter a good deal of new territory, but it is derived in some material respects from our current DX10.1 architecture. The efficiency of the HD 4000 series makes it a perfect starting point, but DX11 requires a lot of detailed work on the specifications that had to be added in certain places. In addition, the Tessellator and hence Hull and domain shader fairly radical changes were required at the scheduler. Overall I would say that our main scheduler that distributes the work of the ALUs and allocates the resources of the individual steps, the component, which required the biggest overhaul. Overall, he is more than twice as complex as in previous generations. When you see the final specifications, you will find that we have other pieces of hardware significantly inflated, including, inter alia...

-All parts have native HD audio support

A new feature in this generation of GPUs will be the 'dual shader engine' though a lot of speculation remains regarding this technology. It's possible that the word defines a new method of sharing graphics memory between the physical GPUs, which would allow multi-GPU setups to be more efficient.

http://www.hardware.info/en-US/news/..._in_September/
Architecture explained by a newb:
Dual core / MCM: This generation supports a new "hard" method of dual gpu rendering that differs from previous Crossfire implementation that we see R800 and in rv870 crossfire situations. The chinese translation is "dual core" or split frame hardware- Has something to do with the way the shaders/alus etc operates inside an individual gpu (a method of simultaneous operations in the hardware, similar to dual core, yet not actually two dies in one package ala MCM). Perhaps there is no more real-time compiler in the driver and its all handled on the hardware level by the scheduler. Because the core of the chip is so modular & scalable with certain areas sharing parts of the die (ROPS + Memory controller logic), you are able to divide the specs in half (1600/256/80/32 to 800/128/40/16) and have two parts (rv870/rv830) and rv870 appears as two rv830's, yet it is still only one die. Hence term "dual-core" - more like "modular". Some people think, yes, but all GPUs are multi-core because each of the shaders is like a core by itself. Well, here we are dealing with two large arrays of 800 shaders, along with other standalone logic that communicates with either one of the two identical arrays. More specifically, one Rv870 die is composed of two Rv830-like 160x5 clusters/shader arrays (like two current-gen revamped rv770's in one die) sharing certain features, but connected via "internal crossfire" working in unison and the entire design is a continuation of R600 architecture. It is load balanced, efficient, and requires no crossfire software optimization (because it is hardware level communication); it works via SFR 8*8-32*32, and is bandwidth intensive. The board is using next-gen 5ghz Gddr5 to provide the required bandwidth. So, apparently they've slapped together two 40nm rv770's... so it's easy to see where "dual-core" confusion comes from. Cypress is like a 40nm 4890x2 in one die! -So, it is like a "native dual core" CPU. Now that specs are known for Cypress & Juniper (rv870 & rv830) you can expect that the remaining parts Cedar & Redwood (rv840 & rv810) are 3/4 Cypress & 1/4 Cypress respectively, and that Hemlock (r800) is 2 x Cypress in the same fashion as the HD4870x2 on a single PCB. So, Cypress is like a larabee, except that it uses 2 rv770 cores, whereas larabee is using several P54C cores. (Even though this isn't an actual rv870 die shot, rather an artist's rendition posted earlier - when you do see an actual one, it will look more like the first two images ie. a symmetrical reflection of two identical core areas over a center axis, rather than the third picture - which is an actual die shot of rv770. Notice in the 3rd pic that the rv770 is asymmetrical by design, not resembling a dual core architecture.)

-Funny, the more i read about this, the more it sounds like dual-core cpus. This could be the first attempt at making a GPU that fits all market segments like modern CPUs. Like how we have Core2duo & PhenomII and 20 sku's of each product with different caches & speeds, but there is really only 1 penryn & 1 deneb, and likewise... 1 cypress.

Not much solid info on these AFAIK, and many of the reports have Juniper/Redwood with mismatched info (like 640/800 SP, but p95xx/p46xx Vantage scores). Also no definite info found about MCM...I also read there may be 480SP and 320SP parts for low-end and that Cypress may have 384bit bus, but that would change up its SP/TMU/ROP counts. Cypress would have to have 4 more memory chips on the back of the pcb - yet unknown
btw- wouldn't the memory pads need to be layed out like this in order to have 384-bit? But who knows... -

-Vantage performance Comparison: (The efficiency of Evergreens performance will depend applications coding, DX9/DX10/DX10.1/DX11, tesselation, use of compute shader, etc. - vantage scores just relative to older series cards)
Hemlock ------~P28k-P30k (4870 quadfire, gtx295 quad sli, or better)
Cypress XT2--- P18,xxx (close to gtx280 sli)
Cypress XT1--- P17,xxx (gtx295)
Cypress Pro---- P16,xxx (hd4870x2)

Cedar ------ ~P12k (GTX285 or better)
Juniper XT ---- P9,5xx (hd4870 1Gb)
Redwood ----- P4,6xx (between hd4670 and hd4830)

TDP estimates: (i think hemlock TDP more like 340w+)

Hemlock is R800, possibly branded as 59x0, 300w TDP(6+8pin) uses two RV870s using SFR. Possibly 2 different cards, one PCB codenamed Trilleon(?) estimated MSRP $499-$599. Slightly longer PCB than 4870x2.

Cypress is RV870, 58x0, 225w TDP(dual 6pin), 256bit, 32ROPs, 1600SP, 80TMUs, ~280-340mm2, performance of around a 4870x2/4890CF. 2-3 different cards, 1&2GB versions, MSRP $249, $299 and $349. PCB slightly longer than 4870(9.5in) so maybe 10in, 2 slot cooler w/ 2 DVI, a HDMI and DisplayPort weird half exhaust in the back.

Cedar is RV840, supposedly a cancelled 192bit, 960SP part.

Juniper is RV830, 150w TDP(6pin), 128bit, 16ROPs, 800SP, 40TMUs, 181mm2, performance between a 4870 and 4890, closer to a 4890. 8.5in PCB(?) single slot cooler reference(?) OC'ed/higher clocked dual slot cooler(?) 1GB. MSRP $149 and $199.
Talk of a lower binned 640SP part to replace RV740, filling the $89-$129 market(?).

Redwood is RV810, 75w TDP, unknown specs- 64bit, 320-480SPs, 24TMUs, 80-90mm2. Performance close to a 9800GT, less than a 4830(?). MSRP ~$79 and under. Low profile version(?).

-Should be a low end rv810 w/ ~40w TDP as well.
From wiki R800 article:

-Sorry if some of the info is conflicting - it all comes from different places on teh webz.

I'll laugh if all this speculation ends up being bogus and like RV870 = MCM rv840, hemlock is the low-end, trillian is a 4gpu dual mcm monster with 384bit bus, and the whole thing is called the Radeon7 series,etc.... But I guess we find out on Sept. 10. If it's true I want a job at one of the rumor mill websites, because I enjoy this.

WTF???
Yeah because like 3-4 sources didn't state that they were rolling right along and might have moved the launch up.
Then AMD SHOWED the silicon and even stated in a financial conference call that they would be shipping products this year.

Good one...
IMO, everyone knew they were launching at Windows 7 launch, even the most diehard Nvidia fans. So I don't even have a clue as to where you fall in line.

It's true, go read any of the threads pertaining to the 5xxx series of cards and their expected release dates. Up until the actual announcement that "something" would be happening on September 10th, there were multiple people claiming that they "highly doubted" AMD would get anything out the door before November/December.

I'm talking about members of this and other forums, not about the press.

I'll try and dig some of the posts up later, but I'm feeling too lazy right now.

So here is what I learned so far (from these guys - hehehe ):



Radeon "7" Family (Evergreen) is 6 parts:
Trillian = "R800" + either multiple montior or 3-way GPU
Hemlock = "R800" Dual GPU
Cypress = "RV870" Single GPU
Juniper = "RV840"
Redwood = "RV830"
Cedar = "RV810"
Press date: Sept 10th, 2009 Event loc. San Fran, USA?
Hard release: Sept 24th. --> mid Nov. 2009
Price range: $500 (high-end) --> $50 (low-end Cedar)

Cypress (rv870) single gpu "HD5870" is:


HD2900XT PCB size
40nm
353mm^2 die size
19mm x 19mm at cost of $34 per die
2x 6pin PCI_E power connectors
DX11
1600SP
256bit bus
80TMU
32ROP
1024/2048mb mem configs
SIMD : 20
Shader Clock : 850 ???
Memory Clock : 1200 ???
Bandwidth : 153Gbps ???
~$350 MSRP
3dmark vantage performance:
Cypress ~P16xxx - P17xxx - P18xxx
aka ~HD4870X2 performance level
potentially an ~30% performance improvement in the same power profile vs. rv770

Hemlock (R800) dual gpu "HD5870x2" is:

larger than 4870x2 single PCB
40nm 353mm^2 die x 2
19mm x 19mm at cost of $34 per die
1 6pin + 1 8pin PCI_E power connectors
DX11
3200SP
256bit bus x 2
80TMU x 2
32ROP x 2
1024/2048mb x 2 mem configs ???
~$500 MSRP
3dmark vantage performance:
(2x Cypress) theoretical P34xxx ???

Juniper/Redwood HD5850, HD5830, HD5770?

Partial shroud HSF design
40nm
181mm^2 die size
14mm x 14mm die
1 6pin PCI_E power connector
DX11
800SP on Redwood
640SP on Juniper
128bit bus
40TMU
16ROP
512/1024mb mem configs???
~$199/$149 MSRP
3dmark vantage performance:
Juniper XT ~P95xx
Redwood ~P46xx
About the speed of a HD4870 & HD3870

All lesser end models (Juniper, Redwood, Cedar) will be limited by loss of memory bus width, shader count, TMU & ROP count, memory size, HSF design, ports & features according to their market placement of either performance, mainstream, or entry-level. Not much solid info on these AFAIK, and many of the reports have Juniper/Redwood with mismatched info (like 640/800 SP, but p95xx/p46xx Vantage scores). Also no definite info found about MCM...

It will be very interesting if the specs regarding die sizes turn out to be correct, since they look to closely match estimates reported by SemiAccurate not too long ago.
