AMD Radeon HD 8990 Rumored for 2013 Launch

Earlier this year rumored specifications for AMD’s upcoming HD 8000-series graphics cards leaked to the Internet. Details on the 8800 and 8900 series cards have since been revealed along with rumored/estimated clock speeds and pricing. One card that has, until now, remained an unknown is the dual-GPU Radeon HD 8990, however.

The existence of a dual GPU Sea Islands card has been especially suspect as a result of the ever-elusive Radeon 7990 and its almost-certain cancellation in an official AMD-branded form. On the other hand, a road map leaked by BitDreams.se and discovered by Maximum PC seems to suggest that an HD 8990 is at least being considered.

The Radeon HD 8990 follows the dual GPU traditions of its predecessors by combining two 8970 GPUs onto a single PCB. That means, if the previously leaked 8970 specifications hold true, the 8990 graphics card will have 5,120 stream processors, 320 texture units, 96 ROPs, and a 384-bit memory bus for each GPU. The card will have between 6 and 12GB of GDDR5 memory (3GB-6GB per GPU). The dual GPU card will have a maximum TDP of 375W and will come with slightly lower GPU core and memory clockspeeds compared to two individual 8970 cards. The GPU will be clocked at 950MHz and the memory will be clocked at 1250MHz. The single GPU Radeon 8970 will come clocked at 1050MHz core and 1500MHz memory, however.

The dual gpu 8990 card, as well as the rest of the 8000 series will support DirectX 11, Shader Model 5.0, and OpenGL 4.2. Bit Dreams lists the maximum single and double precision performance at 10.2 and 3 TFLOPS respectively, making this a rather powerful card that is not quite the same performance as two 8970s but will take up less space. Interestingly, the card would be noticeably faster than AMD’s FirePro S10000 card (essentially two 7950 gpus) at 1.48 TF double precision and 5.91 TF single precision. That would suggest that Venus is much more efficient than Tahiti, if the numbers turn out to be true.

The card will allegedly be released sometime in the second quarter of 2013 (Q2’13). Pricing is likely to be around $1,000 but so far pricing information has not leaked. Even taking these numbers with a spoon of salt, a dual GPU 8000 series card is sure to be welcome by enthusiasts. Here’s hoping it ends up being released (unlike the 7990) and is as fast as it’s rumored to be!

This is just begging for a 27-30" 4K monitor. I guess that makes two of us!

27-30 inch?! Think you need a lot bigger than that to appreciate it! I've never heard of a 4k monitor so small anyway

We will have to wait about next 4-5 years to get a proper graphic card for a decent money,even now cards like 690gtx are overpriced,if we see where are they producted,and that people work for about 1$ per day there,even with transport+taxes they earn about 300-500$ per 1 690gtx,if they are smart,they should look into producing in balkan(europe) countires,u can get a worker for 200-300eu per month there in middle of europe.
Even with 690 if u turn on msaa hbao and other effects on 1080p monitor(in some new games)you get around 40-50fps,so basicly you must get 2x 690 to play on 1440p+ with all settings maxed,we all remember when 8800gtx was realeased cost about 600$+,8800ultra 800$,today u can buy 680 or 7970 for that price and they are actually 3x faster,8800 was released 2006,and 680 2012,so that about 6years for 3x improvment,so basicly 2015 will probably be the year when we can acctualy get what we paid for

O RLI,

Well if you need a good GFX buy it NOW because... if the 8000 series comes it will be 30% faster but 30% more expansive.

Its still based on 7000 series, so i think i pass it with 7950 crossfire i allready have....

However, this process can really take a lot of time and rewriting
the name, number and address of that certain person or establishment can be tiring as well.

Some papers today are made acid free, but most paper collectibles do contain acids and need help to prolong the life of the paper.
Many sites will permit, even encourage you to search their member ranks and some people
really do put up phone numbers there.
