CHIPHELL

For ATI, the execution of this chip-ganging strategy is the key. And this is where ATI appears to have been successful. "The inter-processor communications. Getting that to work has been the trick. This is what ATI has done. They've come up with this stellar way of doing inter-processor communications so they can in fact get the scaling," according to Peddie.

AMD-ATI's upcoming R700 (rumored to be called the 4870 X2) two-chip graphics board will be the ultimate test of this strategy.

"It's a new proprietary inter-processor communication technology. If they put these two chips on one board and it does scale properly, then they have pulled off a coup," he said.

"When you gang up graphics chips (using the traditional Scalable Link Interface or CrossFire technologies) they roll off pretty fast. ("Roll off" implies that performance doesn't scale up well.) "So when you put two boards in, you don't get twice the performance but you (only) get one and a half. You put four boards in and you (only) get about 1.7, 1.8. What ATI is saying is that with two chips using (their) proprietary inter-bus, they will get 1.8 (the performance) with two chips. If that's true, you can expect to see four of them giving you something around 2.5."

Getting 2.5 times the performance from four boards would be a masterstroke for ATI.

The previous ATI dual-chip solution was very different, Peddie said. "The HD 3870 X2 was not a proprietary bus but a CrossFire connection. The CrossFire connection and the SLI connection are at the very, very end of the pipeline. Not the most efficient place to do an inter-processor communication. That's one of the reasons ATI has abandoned it."

Σε μονό PCB 2X4870 με βελτιωμένο LINK CHIP που θα δίνει με βάση τα λεγόμενα καλύτερες από γραμικές επιδόσεις ?

Low Voltage Binned GPUs με χαμηλότερη κατανάλλωση ?

Kατά πολύ ποιό γρήγορο από CF 2 X 4870 λόγο νέου Interconnection Link?

GTX 280 SLI Dominator ?

Tα μισά από τα παραπάνω νa βγούν αλήθεια τότε η NVidia θα πρέπει να πουλήσει κάτω του κόστους.... :happy2:

dag αντε να δουμε και την amd cpu να παει καλα το τελος του 2008 ;)

κυκλοφόρησε χθες ο phenom 9950 που τα πρώτα δήγματα λένε ότι πάει εύκολα στα 3,6 με αέρα με προοπτική να φτάσει τα 4 ghz με το 750 ...

Αμα κάνει Come Back και στις CPU η AMD ...... τότε θα αρχίζω να πιστεύω στα θαύματα. :hehe:

Με βλέπω να ξεπουλάω Ε8400 & Q6600 παρέα με την 8800GTX και να ξαναπηγαίνω AMD με τα χίλια....:clap:

απ ότι φαίνεται σε σχέση με την 4870 ο regulator πιάνει όλα τα ποδαράκια άρα θα πεση και μοντες στις 4870 με μεγαλύτερους regulators

αν χτυπήσει στα ίσα την gtx280 θα πάω να πάρω 2 να αξιοποιήσω το CF στην χ38 μου

ΟΤΙ ΠΙΟ ΩΡΑΙΟ ΓΙΑ ΠΡΙΝ ΤΙΣ ΔΙΑΚΟΠΕΣ-

Η ATi Radeon HD 4870 X2 αναμένεται να βγει στην αγορά στο τέλος Ιουλίου

Η είδηση από τον JC-DENTON aka gznp

Πολύ ωραία , αν και θα γούσταρα και μια 4850 χ2 στα 300-350€ :banging:

2 φωτογραφίες από την 4870 X2

We've seen it take it all off recently and now the Radeon HD 4870 X2 has a little something for all puritans out there,

two more shots of it looking lovely (BEd: You do realize you're talking about a graphics card right?) in black and

equipped with the reference dual-slot cooler. Codenamed R700, the upcoming PCI-Express 2.0 and DirectX

10.1-supporting card has two RV770 GPUs connected via a PLX bridge card that offer no less than 1600 Stream Processors.

Said to be available in both 1GB and 2GB versions, the Radeon HD 4870 X2 will utilize GDDR5 DRAM chips and will

require extra power through two (one 6- and one 8-pin) PCIe connectors.

The card is expected to be launched next month and cost $499.
