Where's mah cookie?

[ChinStrap]

i don't know if this has been said yet, or not. but those new clear pictures have the vGPU controlled by a Volterra voltage controller.

vGPU softmods out of the gate.

which. IMO. is SWEET!

[jaredpace]

hahah!

Well we have to wait for a review to say if the two groups communicate via sfr or not...so it's like the two groups of 800 could just as well have been one large group of 1600, and the thing would operate just the same, just that it was easier to start with two rv770 style groups and work from there? Theres nothing special about the diagram having dual rasterizers and heirachial z?

After anand's review ill likely be sending u cookie

If anyone here noticed, I believe those are die-shots of Cypress.

Hey, that last picture about the "sweet spot strategy" and the market segments for each chip is wonderfully pretty with all those chips images and so, but what I read there is:

Hemlock => 400-500$
Cypress => 250-350$
Juniper => 120-200$
Redwood/Cedar => <120$

What we know right now about Cypress prices is 300-450$, so what are AMD trying to say with this slide? That these former prices they have said are actually inflated because of the novelty?

[ahmad]

As I read those numbers I thought to myself it has been a long time since I last saw a new gfx card from a competitor win in absolutely every single game tested. Until I saw wolfenstien numbers, then I was able to relax

Awesome! A few more driver revisions it will hopefully win in that benchmark too.

Thanks for sharing.

Fast GDDR5 link training
Allows voltage & clock switching on the fly without glitches

Goodbye image flickering due to memory freq change á la RV770/RV740/RV790.

[cirthix]

I spy a vt1165 vgpu regulator control chip, so rivatuner and others should already be able to adjust gpu voltage .

Nvidia's shaders are spread around the die too. Just because it's not all clumped together like in RV770 doesn't mean anything

And yes there's nothing special about multiple rasterizers (well besides us finally getting them). Just like there's nothing special about having multiple ROPs or TMUs. Can we please let the dual-core rumours die? RV870 is a single-die, no SFR or AFR crapping monster.

$350 is a sweet price for the HD5870 considering how much the GTX 295 costs now, but I'm sure the price will be up a little more like when the previous gen first debut. I assume this is the price for the 1GB version, the 2GB might cost $70-$100 more. Much excited but I guess I still hold my breath and see what Nvidia has up their sleeves. Hopefully they're gonna open a big can of whoopass instead of a huge grain of salt.

[Vinas]

Whoever said multi monitor support isn't important are fooling themselves. If the multiple head displays did d3d today then I wouldn't have had to buy that Matrox Triple Head 2 Go a few years ago...

Gaming with 57" on screen real estate is a whole new experience. I play primarily FPS titles like cs source. Heck the 3 screen setup I'm using now carried me through several seasons of CAL IM back in the day... Peripheral vision in games is just something to behold and I wouldn't give it up for anything!

Of course you need the hardware to drive the displays... I get sad when I have to go back to a single display because it runs badly or doesn't support 16x9. Crossfire or SLI is a requirement for my system.

So I hope ATi does have some cards that can accelerate more than one display. It will open up the market to a whole new generation of gamers. My question is can these cards do multi monitor with CF enabled? I'll keep using my TH2go until then...

[jaredpace]

Well I still think the shader group units are semi-independent and communicate with each other to render images exactly how two physically separate modern gpus render in sli/crossfire. There was so much talk of this on the asian BBS's I don't see how they could have just made it up and ran with it. It could all be wrong, but I still want to read a review explaining the rendering process. Apparently to you guys, largon & trinibwoy, it is no different than g80/g200. 2 weeks and then i can send cookie, trini you get nothing but a good laugh.



edit - chopped up image compared 5850 to 5870... 81% to 100%. How to unlock the missing 160 shaders?!?!?!?!

[Helloworld_98]

Guys, is it possible that those 160 shaders help with eyefinity and AA?

[T2k]

okay, then as you say the 5870x2 DOES go against the gtx295. current 295 price is $499, 5870x2 price set to be $599 at end of october.

And it will be cheaper than MSRP when it hits the street, that's for sure, just like it was with any previous generation.
In other words a $500-550 6870x2 will compete with ~$480 GTX295...

But already the $399 5870 1gb single gpu card is destroying the $499 gtx295...

Well, that's a stretch but I expect 5870 to be around $360 on the streets so it's definitely a good deal.

So what are you saying? What is rediculous about what is happening?

The ridiculous thing was that you guys called "only" 10% faster (5870>GTX295) when it's not even in the same class.

What in the world are you talking about? Every SIMD in every GPU is independent. Your're basing your theory on the fact that AMD showed two separate groups in an architecture diagram? So I guess this diagram makes you think there are 20 different GPUs rendering in crossfire?

If this information is true, the HD5870 will be a great card.

[tajoh111]

Thats some ridiculous scaling. Forget the 5870. If the 5870x2 is only 150 more, then it is the card to get. Its more than double the performance of the 5850 and less than double the price. I am basing this off the performance of the 5870x2 comparison.

For the most part the gtx 295 when 4x aa is used appears to be faster than the 5870. However at 8x it loses alot of times. At that performance, I can see NV next generation part being much much faster. It will still lose to the 5870x2 I think but I can see it being 50% percent faster than a single 5870(it will lose to a x2 because the 5870x2 appears to have 100% scaling).

The reason I can see it being 50% faster is because the gtx295 has really conservative clocks on both the shader end and its main clock as well. If the 510 shader part is true and it is indeed a new generation, then I can easily see it 50% percent faster than a 5870.

At that point, NV definitely has a chance because it give NV the opportunity for them to release a x2 part on their own that beats the 5870x2 by a rather significant margin. If NV is able to catch the single and dual gpu crown within 4 months of the 5870 release, then it could win this generation.

Alot of speculation, but the 5870 performane gives alot of room for this to happen.

Since the House passed 100 to summarize it:

We all know that RV870 is a native dual-core, MEM share, TMU sharing, etc. These hardware innovations is just the beginning, or rather in addition to hardware of the new technology, RV870 brings us the updated software in-depth , for example, CrossFire mode, specifically can refer to the savage major technical paper, I did not explain the response to this (http://bbs.chiphell.com/viewthre ... & extra = page% 3D1)
RV870 by native dual-core hardware support, the biggest benefit is the CF model can be evolved from today's AFR for a more reasonable SFR (do not understand what AFR and SFR for us to look savage Great article,), SFR and thoroughly get rid of the PCI-E bandwidth bottlenecks leading to CF or SLI can not use the SFR of the constraints, CF no longer rely on driving on the optimization of 1 +1 is infinitely close to two and said, where everyone will be RV870 native dual-core architecture of the deep deep impress, at least in my case, native dual-core is my first time in years, felt playing card graphics technology, a major step forward.
Go back to Crysis on the results, in fact, the RV870's Crysis performance can be regarded as a strong reason why the bounds of reason, but it can be regarded as lucky, because to say whether it is before the CF or SLI, the efficiency of both in Crysis is not high, RV870 just drill the use of technology, this SFR loopholes and completed card crisis, the role of Terminator, but I hope that everyone calmly RV870 performance, in other CF or SLI more efficient GAME in, RV870 impossible to think about Crysis so lucky, though it in terms of the total, RV870 architecture as pioneered the use of dual-core technology, combined with the many part of the shared framework, the core DIE or the ratio of power consumption and performance will be the same Performance Products the highest, which is beyond doubt.

Lao Lao hastily said so much, would have wanted to test them on the RV870 article says, but I got fascinated by the RV870 architecture could not resist spraying a bit out, more content or waiting for me in the future release of the RV870 test, let us share the bar.
Quietly asked a small problem, AFR to SFR does not seem to call it evolution, can only be called after the performance to a certain extent the development of an inevitable trend of bar

CHIP has the original "Dual" Processor Unit, each PU contains 160 VLIW (vulgar understanding of the words Where there are two RV770 form a RV870), but certainly not in now with a simple package prices
Where CrossFireX decker SLI are AFR (cross-frame rendering), image processing, 2 GPU Where】 【rotation exchange working, efficiency relates to the driver to complete a few quick, the error can not compensate for delay
RV870 with generous SFR (split-frame rendering), image processing, professionals, all know that playing a three-color RGB images must be completed, SFR Where Through 1FPS on screen divided into a number of 8 * 8-32 * 32Pixel generous detailed map between the to carry out the same color with the nuclear deal as long as the Bandwidth咁sample is large enough, you can achieve the same RV770 generous GPUClock case is equal to +200% efficiency.
(SFR consumption on the heaviest Where Bandwidth, RV870XT will spend the world's fastest generous GDDR5)
The above messages are from the Mainland China's internal sources AMD

Praytell why the hell would ATI make a "native dual core"? That doesn't even make sense with GPUs. If they are going to CF two GPUs on one die, they would be better off just making it one GPU. It'd be faster with less overhead and wouldn't cost any more to manufacturer.
Basically instead of making a mega cores with 1600 SP you make two 800 SP cores on the same die with fast inter connects to support SFR. This way you can concentrate on refining process tech for the lower trans count 800 SP cores. It will not be as fast as a native 1600 SP chip but it will be easier to produce. And it appears that the cores share a single memory controller. So I guess instead of calling it dual core it may be better to call it dual shader mega clusters.

[STaRGaZeR]

FINALLY!

The bad news is that probably the low idle power consumption is because the card clocks the memory down a lot, 100-300MHz, not because ATI has done significant improvements in the memory controllers. We'll see.

[~CS~]

To me it seems 5xx is a much of victory to AMD as 4xxx was , it shows some steady growth and it will be a victory in the market as well for few month afterwards only time will tell , but Green has been producing huge chips with alot proprietary adds and ends , no matter what anyone says and they had to learn that lesson with 4xxx and the chances are all that we will see is a shrink with some minor improvements .As to someone saying that NV is being quite , no its not they been spewing propaganda ever since 5xx talk began .As for Eyefinity i really dont care as long as it doesn't take up to much die space .


Edit : ohh yeah "Voltera" voltage controllers are indeed sweet

Rhhhhoooo

3-XFire HD5870 on the road for the same price

[orangekiwii]

I wanna see 5870 X2 to the gtx380 (or even gtx395). Which ever wins (most likely 5870x2) will be my next buy.

I'm not counting on the gtx395 though... if it does get released... it will get released months after words like the gtx295 and will cost significantly more

so my next buy is looking to be a 5870 x2 massive step up from my gtx285 if these benchs are true

hopefully won't be too bottlenecked on a q9550 @ 4 ghz... anyone think it will be?

[vegettoxp]

Hey Guys, I just wanted to give me two cents and also get your opintion on my future upgrade. These news card do sound really good. I am currently running nVidia 8800GT and I wanted to know what Version of the Card would you guys recommend me upgrading too. I am a picky person. I do play gaming on my PC, Blu-Ray, and other Cool Stuff.

I also wanted to ask that I was playing NFS Most Wanted on my 360 and there were alot more Graphics then I have currently on my PC. I play the same game on my PC and there are a lot Graphic Elements that are missing. Does this means that my Graphic Card isn't as powerful as my 360. Your Thougts Please?
