The Chiphell.com have managed to get their hands on what they claim to be a RV670 GDDR3 card.

As we can see from the picture, the card has a single slot cooling solution. As we wrote earlier today, the card should have a TDP of 135W, so it seems that the 6 pin power connector might be reserved for PCIe 1.1 motherboards. Since the card is made in 55nm the single slot cooler should be enough to cool it down.

You can check out more pictures here.

RV670, ATI's first 55 nanometre chip turns out to be better than anyone inside ATI expected. ATI planned to have the chip ready in very early Q1 next year but for the first time in ATI's history the A11 silicon doesn't need a re-spin.

Traditionally A12 was ATI's production revision but it looks like that A11 is bug free and that it is ready for production.

It was about time that ATI got something right.

Our colleagues from Chiphell.com have posted more design pictures of the RV670 based GDDR4 card.

The card has a dual slot cooling solution with the heatsink that covers most of the card. The guys from Chiphell also managed to get their hands on TDP table for the entire RV6xx line-up, some of them are still "to be disclosed" but you can check out the TPD for the RV670 GDDR3 and GDDR4 cards.

The TDP table confirms our stories about the RV670 TDP. We wrote that the faster iteration, codenamed Gladiator will have a TDP of 135W and that the slower one codenamed Revival has TDP of 105W. Looks like ATI struck gold its 55nm process.

You can check out the rest of the pictures at Chiphell.com.

GDDR4 card design

_____________________________________

Good for high mainstream part

RV670 is closer than most of you think. The cards will be out in October / November time and we got the TDP for the second card, codenamed Revival. This is the new PRO card and Gladiator is the new XT part but ATI can use the different codenames.

The actual power usage is 80W which is definitely not bad for a card that will have close to R600 performance. I guess that 55 nanometre will be a good process for ATI but we will believe it when we see them out.


It looks good now.

Other Pics And Charts

_______________________________________

The Coolaler.com forum has posted pictures of what appears to be the RV670-XTX card. Actually, a sticker on the back of the card shows that it is a RV670-XTX card. The leaked card has a 256MB of memory on the 256-bit memory interface.

It is based on a 55nm GPU that works at 600MHz. The PCB is the same length as the HD 2900XT card and it is an Engineering sample made by ATI. It has a six pin power connector and uses eight Hynix HY5RS573225B GDDR3 FP-11 memory chips which are rated to work at 900MHz.

RV670XTX

________________________________________

AMD has been very successful with RV670 so far with performance above expectation. There will be 2 SKUs; Revival and Gladiator as we have mentioned before and the TDP for Revival is 104W and Gladiator is 132W. AIB partners have already received the Revival sample cards and design kit so we can expect to see some nice cards at launch. Gladiator cards will be next. AMD plans to launch RV670 by mid November with prices range between US$229 and $299.

AMD Plans To Launch RV670 By Mid Nov

_________________________________________

We already told you a few times that ATI's next generation graphics will be two chips on single card but ATI has two codenames for it. One and most commonly used was R670 but in the last few months ATI started using R680 codenames.


R680 is nothing else than a different codename for R670 or should we say dual chip card. In middle 2008 ATI plans to introduce R700 a brand new marchitecture so this will be the new chip and not the R680 as some people thinks.

R670 is R680

__________________________________________

According to theoretical numbers RV670 will be as fast as R600. I guess this is ATI's dark secret as RV670 is indeed an improved version of R600.


The RV670 at 750 MHz has 480 Gigaflops processing rate while R600 at its 472MHz has 474Gigaflops which implicates that the chips will have the same performance at the same speed.


ATI's dark secret is that at maximal 825MHz the chip can gain additional 50+ Gigaflops but we still believe that RV670 has to lose to R600 in high resolution with FSAA and Aniso on due to its 256Mbit memory interface.


RV670 its its three iterations comes in November.

RV670 score same Gflops as R600

___________________________________________

VR-Zone learned about Radeon HD 2950PRO (RV670 Revival) scoring around 10.7K in 3DMark06 sometime back with a good old FX-62 CPU. INQ now revealed that RV670 will score around 11.4K, some 600+ points higher than Nvidia's G92 reference score of 10.8K on the same platform. We heard that it was benched using a fast Core 2 processor. If all these figures provided by AMD and Nvidia are accurate, it looks that RV670 has an upper hand now. Also we heard that Nvidia wants 8800 GT to be launched at least 2 weeks earlier than RV670 so it could sell as many cards as possible before AMD ends their party on Nov 19th.

RV670 vs G92 Battle Heats Up

___________________________________________

The base of RV670 design is the R600 architecture and ATI learned a lot from its mistakes. Nvidia overclocked Shader speed really boosted Nvidia's performance and ATI simply could not catch up.

It was a time for a new strategy. The RV670 is a redesigned and improved R600 core done in 65 nanometre with official support for PCIe 2.0. The base R600 design is improved with UVD and this is a something that was missing from this big card.

ATI added Shader model 4.1 and DirectX 10.1 support for this new core. At the same time the company claims that it managed to improve antialiasing performance and at the same time that it managed to reduce the memory interface bandwidth. The anisotropic texture filtering quality is also improved and at the same time ATI managed to reduce the transistor count.


We will soon see just how fast this new card really is.

What's improved on RV670

____________________________________________

ATI's upcoming flagship 825MHz clocked Radeon HD 2950XT can score 528 Gigaflops. These raw Gigaflops numbers indicate that in raw calculations it ends up faster than the original R600 core. At 742MHz an R600 core based Radeon HD 2900XT scores 474Gigaflops which is significantly lower score than what new chip can do.

The key element might be two flops per unit powered 320 Stream processor chip. This is not something new the original R600 managed to do this but still RV670 will be limited with 256 bit memory controller which will have to mean a slower performance at high resolutions.


Still, at a $249 price tag it looks quite good.

Radeon HD2950XT scores 528 Gigaflops

_____________________________________________

AMD has informed their AIB partners that RV670 launch date is brought forward from Nov 19th to 15th and the official marketing name will be determined by next week so Radeon HD 2950 nomenclature is not craved in the stone yet. We can expect a hard launch from AMD this time round. However, 790FX (RD790) and AMD 770 (RX780) launch date is pushed back from Nov 5th to 20th so it would be a separate launch like Nvidia with their 8800 GT (Oct 29th) and nForce 750/780 series (Nov 12th).

AMD RV670 To Launch On Nov 15th

_____________________________________________

Eight MHz faster than R600

The $199 RV670 PRO with its 55 nanometre process will end up clocked at 750MHz. This is whole 8 MHz faster than the previous R600 core. The new card will have 320 Stream processors and the number remain the same for the old R600 and for RV670XT and PRO.



The card will score 480GigaFlops which is again only 6 GigaFlops faster than the R600. ATI will have these cards available in middle November and it looks that Nvidia is on the schedule to launch in late October and to have the cards in retail at the first launch day.



Both R600 and RV670 XT and PRO have two Flops per unit. For all of you that didn?t know this already FLOPS stands for FLoating point Operations Per Second and this number is very important in both graphics and especially in GPGPU business.

HD2950PRO works at 750MHz

_____________________________________________

ATI is still on schedule to launch its Radeon HD2950 in November and it looks like Nvidia will launch its Geforce 8800GT cards on the 29th of October, a whole two weeks earlier.

Nvidia will have the lead, but if ATI launches anything sooner than the planned 15th it might be a pure paper launch. According to the current schedule, the drivers will be finished days before the launch and ATI was counting on Nvidia?s November the 12th launch date, but Nvidia will launch two weeks earlier.

There might be some controlled leaks if RV670XT turns to be better than Nvidia but we cannot confirm this at press time, we just know the date. Nvidia bashes the RV670XT at 825MHz and thinks that its 600MHz 8800GT is faster but we will hold our breath to them both before we decide who wins this round. We have a month to go until the Radeon HD 2950XTX and XT launch.

Radeon HD2950 launches on the 15th

_____________________________________________

The slowest RV670, the RV670GT will dissipate 80W and will be one of the few cards that will be under a hundred watts this year. The PCIe 1.0 specification can feed your card with 75W of power while PCIe 2.0 can serve up to 150W per PCIe connector but for the safety and compatibility reasons Radeon HD 2950GT will come with a single 3x2 power plug.

This card should do fine even without the connector on a high end PCIe 2.0 board, but then again we believe that ATI will ask you to plug it anyway even on PCIe 2.0 boards.

The Geforce 8800 GT also needs a power plug and so will Radeon HD 2950PRO and XT.

Radeon HD 2950GT dissipates 80W

______________________________________________

HD2950 is no more

We've just received news that ATI might use a different name for the RV670 and won't call it HD 2950 after all. The RV670 might be known as Radeon HD 3000 in the future and this will certainly push expectations even higher.

Gecube jumped the gun on this, and there is even a Radeon HD 3800, but our sources have confirmed that the final name has not been set yet.

As far as we know both the HD2950 and HD3000 names are possible.

Here's a screenshot of GeCube's site, and here's the link.

RV670 to be renamed HD 3000?

Gecube Radeon HD 3000 PCI-E Series

________________________________________________

Until the launch

We are expecting a 825MHz clocked Radeon HD 2950XT, or RV670XT how most of ATI calls this card, but the clocks are still not final.


Sources close to ATI have confirmed that the clocks are going to be the last thing to be finalized and at this time we can't really say what are the final ones going to be.

The RV670XT might end up working at 825MHz but it might be a bit faster at the end even slower if something goes wrong. The good news is that ATI is back on track to fight Nvidia at the time of their G92 launch with a similar part.

RV670 clocks still in the works

________________________________________________



IT SEEMS THAT AMD is just about to overtake Nvidia in the battle of higher numbers. Since Nvidia is so high on extending the life-line of 8800 brand with the G92_200 series being called 8800GT, AMD saw the golden opportunity.

With G92 supporting DirectX 10.0 and RV670 supporting DirectX 10.1 API, marketing war was set to be quite interesting. From one side, calling a mainstream part that can beat the high-end part 8800GT instead of 8900GT was a safe call for Nvidia, and riding the wave of brilliant success what 8800 is - but it seems that people like Pat, Captain Hook, Jon, and Ian are pulling things in a different direction.

The RV670 is more than a die-shrink of R600. It fixes a lot of inefficiency issues that ATI faced with a long-delayed child named R600, and now with 55nm process, there was enough room on the die to go large, both with precision of units, data formats, cache sizes and of course, API support.

Not a lot of people know that main target of RV670 is to establish CTM as a viable alternative to Nvidia's Tesla, thus GPGPU and professional 3D were very high on priority list. We already know that R600 variants in FireGL versions are demolishing Quadros (for the very first time in history of professional 3D, ATI has a real contender), so FireGL and FireStream guys are awaiting their RV670 chips with great expectations.

Radeon HD3700/3800 gets ready for a launch...

So, what to do with a product that has a huge challenge instead? Not burn it with a brand name that is somewhat tamed, and that was Radeon HD 2900 series. 2950 was a stillborn from day one, and now the marketing team is deciding between Radeon HD 3600, 3700, 3800. Taiwan just got the nod about HD3000 series, and we're just about to see the new chapter in the whole Marchitecture wars.

Greet Radeon HD3000 PCIe series with its member HD3800... or is HD3800 another deliberately leaked name in order to get leaky suspects?

The name is not decided yet, and don't expect it to be announced to partners up till the point of printing retail boxes, which is still some time ahead (but not a whole lot time left).

The move to HD3000 has to leave enough room for upcoming Q1'08 monster called R680 and of course, the mega-daddy MCM chippey named R700. R680 will be branded as Radeon HD3800 or HD3900, thus leaving very little amount of marketing space for the R700.

Realistically speaking, only logic for AMD would be to brand the RV670 " Radeon HD 3700", since this would leave enough room for R680, R700 and of course, R(V)710 and R(V)730, the value variants (they would probably take the usual x400 and x600).

Unless of course, HD3000 series is the final "HDsomething" coming from AMD, with completely new branding that may or may not wait in the halls of Austin and Markham. Radeon 700HD just may not seem all that far fetched, just take a look at the world of AMD chipsets.

One thing is certain: when it comes to number of sudden turns and unexpected situations, Mexican soap operas might want to take a page from the AMD/ATI/Nvidia book. [/b]

RV670 to get a name at 11th hour


New SKU

Look this where found in a new driver:

"ATI Radeon HD 3800 Series" = ati2mtag_RV630, PCI\VEN_1002&DEV_9500
"ATI Radeon HD 3870 " = ati2mtag_RV630, PCI\VEN_1002&DEV_9501
"ATI Radeon HD 3850 " = ati2mtag_RV630, PCI\VEN_1002&DEV_9505
"ATI Radeon HD 3800 Series " = ati2mtag_RV630, PCI\VEN_1002&DEV_9507

So the rv670 supposedly has the full fledged r600 core only clocked lower and using a smaller process? I wonder if the r600 will also transition to the smaller process soon, seems like that would help keep the cost and power consumption down. Unless, of course, that process is not intended for high clock speeds...

If RV670 can offer a performance similar to 8800GTS, I'm sold by its single-slot cooler.

My only concern for the r6xx cards is the performance hit they take from enabling AA. If Ati can fix that issue, and the rv670 can achieve the performance of a 8800gts (maybe if it overclocks well), I'd be all over it.

It looks like this die shrink will do wonders for ATi's thermal problems. I just hope that single-slot cooler isn't loud like such coolers typically are on higher end parts.

no, it is an underclocked 2900xt. instead of 740/1650 it will be 600/1600, at least according to his' website. everything else appears to be the same.

is the Rv6070 ATi's next fastest model? if so it sounds like good news for them, i hope the next ATI card can put them back in the race.

Definitly no reason to buy the new 2900Pro if the new ATI XXXXPro is going to be released in Oct/Nov. Hopfully it will chew through these newer titles and DX10 titles.


This is going to be one of those ATI Vs Nvidia Showdowns......woooohooo let battle commence!!!!!

This is what I was waiting for. A cooler R600 that uses less power. The drivers seem to be pretty good for Vista thus far so I'm hopin for the best

While this looks good and all, remember that NVidia plans to release their next-gen series late this year... hopefully ATI can use this as a springboard for R7xx or whatever their next line is, and quickly.

I'm not expecting the r700 to show up anytime before Jan 2008. If the rv670 performs on par with the r600 only costing under $300, it will sell well, even without the halo effect of a high end card. It looks like the 55nm process gives Ati significantly more breating room in terms of die size and power consumption, but it will take time to produce a new high end gpu on the new process.

We're talking about a different card, one that has shrunk to 55nm and will be coming in Oct/Nov.

Are there any after-market heatsinks that work for the R670/R600? I see the HR-03, and that would be a great single slot cooler if you put the card in the typical spot at the end of the expansion row.

Remember the 7900GTX had an 80W TDP?

and the 7900GT had a 60W TDP.

Those were good cards...

Except for the 7900 GT's cooler, which blew chunks.

The 7900 GTX's cooler however was one of the finest ever made.

I had the 7900GT. I would say the fan was "moderate". It could be heard when a game was fired up. My GTS is not silent either, but quiet.

I can agree to that. I have the BFG 7900 GTX OC, and even at 100% fan, cant hear it. And it idles at 38C and at load it has never been higher than 45C. So yea.

Let's hope these parts do actually get out in October/November and that they are good so we can have some more competition.. Looks like I might have to wait for these to come out instead of waiting for the 2900Pro or GT. thanks for links OP

The leaked card has a 256MB of memory on the 256-bit memory interface.

That's worrisome. Less performance than 2900 Pro, but the price range ($229 - 299) occupies it? I hope AMD-ATI isn't serious about this.
