Radeon 7990 release?

Just wondering if anyone knew the release date for the 7990? and if it will be more powerful than the 7970?

I'm working on a 3000 gaming build that I want to have completed in the next two months. I'm pretty much ready to order every component but the video card. Originally I wanted to run crossfire 7970's but I realized that the 7990's would be coming out eventually. If anyone has an answer (or an estimate) that'd be great.

Dont know an eta on release

yes it will be better than the 7970

it will be around 80-90% the performance of 2x 7970's in crossfire.

this is based on experience from the 3xxx 4xxx 5xxx and 6xxx series cards. the dual GPU cards are always just a bit behind 2x the single top of the range.

So dual 7990s would obviously perform better than dual 7970s?

Dual 7990 = 4x 7970 so you need a 4x Cross Fire wich you can't get on the 1155 soket mobo you need a lga2011.

P.S. also what kind fo resolution are you playing on ? Because a single 7970 will cap any game in 2560x 1600p the 7990 will cap games for quite some times.

The only reason to go for something more powerfull would be a multiple monitor set-up.

yes but with previous generations (6xxx, 5xxx & so on) 3x 7970's would be very close to the performance of 2x 7990's. (As scaling drops off quite steeply after 3 GPU's)

With the 6990 it was more like 2x 6950's in CF rather than 6970's

id say 7xxx would be the same 7990 would like 7950's in crossfire.

if it was me id get 3x 7970's over 2x 7990's

good chance that it will be a fair bit cheaper. less power consumption and heat but will be very close performance. and 3x 7970's will look sweet.


again because the hardware is not yet released all we can do is base this on previous generations of ATI cards.

the 7990 will come out in march (or so rumors say) it will be 95% as good as dual 7970's if u overclock itll be about 99% as good

@xtremegamer2da-max

the 7970's will over clock higher than the 7990 as the single cards have much better cooling and they already start out at a higher MHZ for core and memory.

So i think ill just stick with the dual 7970 idea. itll be easier so i wont have to wait until late march, early april for a release. either way i think it will run great with the amd fx 8 core set up. thanks for all the feedback

Are you on crack? Why would you get a 7990 for a 3k build? Get a balanced system, not an op 7990 + shithouse cpu/ram/mobo.

If you really want to know, 7990 will be released after March 6 after CeBIT.

DO NOT GET AN AMD CPU RIGHT NOW. Especially with multi gpu setups. Either get a 2600k, 3930k or wait for Ivy Bridge and overclock the **** out of your CPU.

No the 6990 isnt like 2 6950's. The 6990 has stream proccessors of the 6970 X2. they slightly downclocked to keep under a thermal threshold which is why they enabled the dual BIO's feature in it which clocks it to the 6970's speeds. '

As for the 7990, the will more then likly be following the same concept for the card. Two 7970's slightly downclocked so that the thermal on the card isnt overly high. As for the performance it will be dependent on if they have the dual Bio's with the ability to have the card at the speeds of the 7970 card.

For the abilities for motherboards supporting two dual GPU cards, the board only has to support the ability for dual crossfire not quad. Ull see Asus boards say quad on their boards as marketing but its not needed. Im running two 6990's on a Gigabyte P67-UD5-B3 which only has the ability two crossfire two cards but all cores work. The reason for this is that they are a single phyiscal card.

The 7990 will probably have the rough performance of 2 7970's with the Bios's switched over to not allow the downclock to happen.

And why do u say this. As of right now most games that you will be playing with a dual GPU card have been optimized to have little FPS difference from an Intel to a AMD CPU. As for going with an I7 i would say go with an I5. I7 for the money for games have less then 1% extra performance, and the new 3930K has sometimes less performance then the 2600K in games making it even less worth ur money then the 2600K.

I have an I7 2600K and got the overclock to 4.8gh/z which iv been able to do with the I5 2500K and had no FPS difference in any game running 2 6990's. Iv also seen the new FX8150 score the same FPS in BF3 and metro 2033 as the I7 2600K which would be the primary game people would be getting a system that strong for.

I would say wait in ur case, iv gotten word from my suppliers from where i work the 7990 would be around 900 bucks when released, and as it stands right now the 7970 is 600 so u would save your self some money if you when the dual GPU route. Check the performance on the websites when the reviews come out.
