AMD just took the wraps off their ATI R680, RV620, and RV635 graphics cores. The new R680 consists of two 55-nm processor cores with CrossFireX support sharing the same specifications of the RV670 processor at the heart of their Radeon HD 3870 -- thought to be AMD's best product of the year. The RV620 and RV635 GPU cores are nearly identical to their RV610 and RV630 processors only in a new 55-nm form. Now, imagine if you will a pair of ATI Radeon HD 3870 X2 (R680) cards running in CrossFire. Or say four with CrossFireX. Feels good, right? You won't have to wait much longer as the R680 hits in January.

...it seems AMD is pushing real hard to launch it in January 2008. Apart from DX10.1, SM 4.1, PCIe 2.0 and UVD support, it also supports display port and next generation Crossfire. We learned that R680 has 320 stream processors like the R600 and supports double precision floating point. So effectively, R680 is an enhanced R600 with finer process technology and more features. CJ told us that R680 is clocked at 800Mhz+ and comes with 512MB or 1GB GDDR3 memories but we knew that R680 supports GDDR4 too. Most likely it will come with 512-bit memory interface. Along with R680, we should be seeing RV635 and RV620 replacing HD 2600 (RV630) and HD 2400 (RV610) respectively as well as HD 2950 Pro (RV670) to form a complete top to bottom line-up










Here is some leak pics of R680. There are only three main chips on board, 2*RV670XT and one PLX chip for two GPU commmuications.

All 16 memory chips (8 on the front and 8 on the back) are missing on the board. Source said the card is using 0.7ns GDDR4 memory.

Also we can notice two digital PWN power modules.

i am praying for 3850 and 3870 to drop too...
hope can get 3850 512mb at rm500+...hehe

this card is so looooooooooooooooooooooooooooooooooooooong

As Westerners say, the longer, the better.*


*Although some women do like it wide.

"Most likely it will come with 512-bit memory interface".

I doubt this.

LOLZ hope the card can beat nvidia 8800 series card haha

yup hope its can beat 8800.although use it hehe. If competition great to end-user. Competition will made end-user get better and better technology and product

Where you pointing at mate?
The card or "something else"?

Just Joking.

can't wait to see the result of this card

the price is .....?

btw, where is the RAM chip?? it looks missing from the PCB

the pict of the naked card doesn't hv ram chip, this one reference card (unfinished)

Which website you got this information ?

Does it support X4 Crossfire? 8 GPUs must be insane!

Holy cow. But im just wondering,do we really need so much power? Well unless u want to be future-proof. But that ain't gonna happen to coz technology advance almost everyday.

Holy sh~ cow.... dual gpu dx10 card? better hope for good performance card with value price....

... as usual mate, moding time!
