The Rumor Mill & Whats New 4970 4890 4750 ect

[Niku-Sama]

alright i have my thread and another thread and theres alot of confusion by whats comming out, i'm confused too AMD/ATI is doing some funkyness with things and their numbering system and i have found there are a few places that have one view of a piticular chip and another place will say its this same chip with more umpf so heres what i have found so far.

the 4750 is new and seems to not be wide spread knowledge so i am tossing it in here, this can be a Rumor/New card thread confirmed or not

RUMOR
4970
950Mhz Rv790 an "overclocked RV770"
55nm
900Mhz DDR5
800 stream
??? texture
info from:
http://en.expreview.com/2009/02/23/vote-rv790-is-nothing-more-than-super-super-overclocked-rv770.html

RUMOR
4890
850Mhz "at 1.3V" RV790 "RV790XT"
no word on process
975Mhz DDR5 "likely"
no word on stream and texture processors by VR zone
http://vr-zone.com/articles/amd-to-launch-radeon-hd4890-in-april/6578.html?doc=6578
960 stream
48 texture
according to techtree india
http://www.techtree.com/India/News/AMD_to_Unveil_ATI_Radeon_HD_4890_in_April/551-99054-581.html

CONFIRMED
4750
700Mhz (max) RV740
40nm
800Mhz DDR5
640 stream
32 texture

the 4970 and the 4890 are probably the same thing and there is conflicting info on weither or not its truly an OCed 770 or if its a real 790 with more streaming processors and a moderate jump in core speed over the huge jump in core speed over the "OCed 770"

i would devote more time but i have some phoney calls to make about my moving situation, i'll scour more later on and mabe something else will come up

[MooMasster716]

Looks like ATIs architecture allows them to develop a NEW mid range cards.

[Zurvan]

Nothing more than 800 SP 55nm is coming until Q409
We'll know in a month anyway :beer:

[Niku-Sama]

some more 4890 info
nothing but clocks speeds, reviews soon though
http://vr-zone.com/articles/amd-radeon-4890-rv790-exposed/6758.html?doc=6758

probally to expect the $50 drop of the other cards at about the same time

whatt? $120 4870's??

[Firestrider]

Yep, apparently the 4890 is confirmed: http://www.ocheaven.com/news_view.asp?gid=6754

While it was just talk... the 4890 isn't just a standard it has a new board and pin layout on the chip, supposedly its more efficient clock for clock and has better shaders in it. Take it for what its worth saw that over at XS which I think was linked to FUD site.

[Niku-Sama]

that would be nice huh?

but at the same time is the 4890 was the same as a 4870 is now and it was 15% faster i would probally go for it....with 1 gig though.

i am so tired of 1366x768

[mastrdrver]

I'm hoping that it matches the 285. If that happened, then I think it would be safe to expect a x2 version which will be faster than a 295. Though, it might have two 8 pin connectors (just a guess).

[Badbonji]

It isn't evem confirmed yet, and I am sure nvidia will be releasing 40nm gpu's soon to replace the GTX285/295.

3rd Quarter at the earliest right now.

[Dapman02]

I don't think nvidia will becoming out with 40nm soon. They just got to 55nm

[ghost_recon88]

Yep, you won't see 40nm out of nVidia any time soon.

http://www.dailytech.com/article.aspx?newsid=14480

One solution was to begin manufacturing on the 40nm bulk process like ATI has done. According to our sources, NVIDIA's attempts to produce a die-shrunk 40nm GT200 chip were "disastrous at best".

[Badbonji]

I am not intending to upgrade yet, I want DX11 cards so I won't need to upgrade much once I start uni, I will hate the feeling that my pc will be aged by the time I finish, but then I can get lovely new parts for it once I finish my course :)

so taking their current line, shrinking to 40nm and calling it a new card and giving it a new name?
I have been holding out for the new ATI card, i almost grabbed a 4870 about 2 months back but somehow managed to hold out!

didnt you know, thats nvidias new business plan, shrink and rename, rinse and repeat.....which frankly i am tired of and the lack of the fact that older hardware cant keep up like it used too which seems to affect nvidia more than ati now.

i just hope that the drivers arent as big of a cluster **** like they used to be back when i had my all in winder pro with funky so-dimm memory upgrades.

[Mr.Guvernment]

ATI drives have been awsome pretty much since Catalyst was born, prior to that it was so so, but either way now both NVIDIA and ATI have their problems with drivers.

[Niku-Sama]

thats true but their drives used to be horrible but thats been about oh....wow 9 years?
didnt realize it had been that long but i guess it was a card that only had a few megs of ram on it before you added an SOdimm.

[Dan0512]

It seems the 4890 is just an overcloced 4870. In the recent Vantage benchmarks (@ 850 Mhz core), the GPU score was around 13% higher than a regular 4870, which corresponds to the 13% (core) frequency increase.

I'm taking those rumors about more efficient shaders and whatnot with a pinch of salt.

Pricing and launch dates are still being adjusted at this time. AMD recently tried to lower prices on its Radeon 4870 and 4850 cards, but its board partners believe that the performance of the Radeon 4870 is too good to lower prices further.

[Badbonji]

So what do you think of intel when it does exactly that bar a few minor changes when die shrinking? My card runs hot, and 40nm would help overclock as well as keep it cooler in summer. Intel does it with their cpu's all the time, and it has seemed to work recently (Kentsfield -> Yorkfield, and will happen to Nehalem also). And the fact you are looking forward to a card exactly the same card with higher clocks, WITH A NEW NAME? Not to try a start here, but everyone does it.

[deathman20]

Yeah but with die shrinks on CPU's Intel adds more to them, weather its cache, more instruction sets, better controllers, more work per clock. Its a little different than what nVidia is doing with there die shrinks which is basically a straight conversion with no improvements except in the power front.

Hey there is more to it than that with nVidia.

It gets a flashy new name that implies it is a new architecture (a la 250)

If they just die shrunk and oced the 4870 I will be fine with that unless they try and call it the 5870

thats lame, ati is trying to keep costs down so they can get a leg up on competitors but the 3rd party doesent see it and is being kinda an ass...

very strange, i'm sure they'll pull something though, like 4890 $5 more than 4870
