960 SP-laden RV870 in the Works, and more

Sources at TSMC told Hardspell that the next graphics processor (GPU) by ATI/AMD, the RV870 in the works have specifications such as:
  • 40nm or 45nm fab process
  • 140 sq. mm die size
  • 192 ALUs, 960 stream processors
  • 256-bit GDDR5 memory controller
It is believed that this GPU could perform 1.2 times better than RV770, purely based on the paper-specs.

Another interesting news is that R800, unlike its predecessors the R700 and R680, might not be a dual-GPU card but the world's first dual-core GPU.Source: Hardspell

Guys use your brain... whats the point of dual core for GPUs? Its the same as just doubling the shaders/ROPs :rolleyes:.
Bingo. GPUs are already multicore.

Shaders can't be called 'cores'. Core = shaders + ROP + all the crap that's in the GPU schematic. As to the 'doubled' argument, it's modular for ATI to slap two dies onto a package, or use just one die as a RV870. Think of it as a Yorkfield CPU, where two Penryns are slapped onto it, the same single Penryn makes a Wolfdale, in to two, it makes Yorkfield.

Im curious about the Dual Core GPU's myself Especially Since ATi have the support of AMD behind them - there shouldnt be a reason why they cant make it do'able.
AMD isn't doing too well in the Dual Core processor's itself.

Oh? My Athlon X2 5600+ is doing just fine :D

r870 quad core will be as big as single core GTX350 and 4 times faster than gtx280 :) nice :>

Another small point, Nvidia are not coming up with any new architecture types themselves. Look at the specs for the GTX300, still no Dx 10.1 present.

If you ask me, i'd say ATI have found a solution to making their dx 10 GPU designs faster, and that this new (or upgraded) GPU is going to be faster than anticipated once again.

yes, that is sad, they could easly deploy DX11 (specs ar coming out soon) i think that something must be wery wrong at nvidia, they stuck at G80 arhitecture

ok but we have to ask our selves is this already the specs for the 2 cores put together or is this beast going to have 1920 stream processors form what im aiming at now is ATI is going to stay budget conscious and keep it small. As for nvidia its again a monolithic if the specs are true the Nvidia card will destroy this because of its 512 bit GDDR 5 unless the initial count of 960 stream processors stays the same. But with a 512 bit GDDR5 @ 2gigs the Nvidia card's price tag is going to be as epic/monolithic as the GPU itself. But then again it only has 480 Stream Processors so its going to rely on memory bandwidth alone. I dont know from the paper if i can get a 4 - 2 GPU cores in the same die package as the other guy......:shadedshu

as u can see 512bit (radeon 2900) still doesnt do the thing it is slower than 256 bit radeon 3870.
i think that 512 is nota big deal. it is not going zo be twice as much fast as 256 BIT.
I think that we can expect up to 4 cores as one chip

WOWeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee, finally some speculation !!!!!



Its been so quiet last few days after the performance numbers for 'Spartan' came out , finally something to discuss !!!!


What i think ?

This new card is just like moving from HD2xxx series to HD3xxx series, except that ATI doesn't have a flawed product like HD2xxx this time something like INtel's tick tock strategy . So they can build upon their strengths of HD4xxx.

So expect to see :

Reduced power consumption

HD2xxx to HD3xxx ( 65nm to 55nm )

HD4xxx to HD5xxx (55nm to 45nm or 40nm , more difference than above, hopefully )

I expect to see 20% performance increase

i dont think ATI will improve the architecture with a new fab increase, since a new architecture on a new fab process involves great risks, which is the last thing ATI needs right now.

The new cards will just be refined, kinks ironed out , maybe powerplay , something like GT200's idle 25W power consumption .

exactly, r870 has a root in r600

Is this AMD's tactic to get shareholders to hold onto their shares?
It's not just the same. In terms of performance it should be if done right, however it should give better yields than one huge monolithic GPU, and this has been the reasoning for AMD's dual-gpu tactic all along. It's more economical and will improve prices and profits.

to the issue at hand this is purely speculation at this time but looks very promising, i think ati finally got sick of having there asses handed to them by nvidia, and the gap was closed with the 48** series, if the next gen cards can close that gap even further thats all good news in my book :toast:

In this batch of apples there are red & green. But there is only one type of lime.
The green apples are the R600/700/800. These cards are the best in their league. The limes can only match or take them by doubling themselves.
The red apples are the RV670/770/870. The limes don't care about these cards because all they have to do is water themselves down alittle to match them.
IMO, the apples & limes need to get together & make some nasty fruit pie b4 the watermelon comes crashing down & take 'em both out :D

Heres the big question about the R800:

Yeah its dual-core, but is the memory shared?

I suggest eveyone stay on topic an just stick to worrying about themselves.

I would happily stay on topic, in future what I'll do is report peples posts that I don't like and that I deem off topic. Like posting deliberate jibes at other members posts (post #8) followed by obviously condescending posts (post #14). Nice one.
Oh and to remain on topic, this card is going to be amazing.

Well, staying on topic isn't what I just discussed with you over a PM. If you have a problem PM a moderator, or report the post. Don't post on the thread that you "are going to do it" or that you have. This isn't up for discussion here. On topic, or don't post.:slap:

That's good and all, but if it isn't too much faster than the 4870 then it really won't be worth buying now would it. That 20% would put it in exactly the same range as the GTX280 & it would only translate to a few fps in games. Also by then, the 4870 will be cheap as hell. That baby better be a dual core or it will fail, epically.

lol anyways this comes as no surprize, it' supposed to be smaller cooler rv770 with a few more sp's probabaly fix any issues on the rv770. think of it more like the x1950 was to the x1900.

Or the RV770 to the R600 too! :toast:

1.2times the 4870 isnt all that. its probably the same as the gtx280. owell anything faster is great.

ati must make the base bit for new card now 512 and go more , to help it have good performance like new gtx 350

They also can up the number of transistors with the smaller process. That will definitely help the performance ratio. Too bad TSMC won't give us the transistor count.
They must have it really good, working with both companies & everything. One extra tid-bit & it creates a huge conflict of interest. But we'll take what we can get.
