More RV560 and RV570 details

DailyTech previously reported ATI would be launching 80nm mainstream GPU parts in the near future. The new RV560 and RV570 80nm parts will launch in August and September of 2006 and integrate the CrossFire compositing logic onboard. This will allow dongle-less CrossFire compatibility with CrossFire capable motherboards. Dongle-less CrossFire will not move all data across the PCI Express bus however. Motherboard manufacturers told DailyTech a separate bridge would still be needed for dongle-less CrossFire.

VR-Zone may have snapped a few images of the required bridge shown behind closed doors to partners at Computex 2006. The new CrossFire bridge appears very similar to the NVIDIA SLI bridge.  Never the less, there will be no need to find specific master or slave cards with the new RV560 and FV570 parts as all cards will have an onboard composite engine. The VR-Zone image shows two bridges connecting the two video cards.

Motherboard manufacturers have told DailyTech an ATI board will not be required for dongle-less CrossFire, however these same sources also originally claimed CrossFire on RV560 and RV570 wouldn't require a bridge like NVIDIA's SLI.

who cares,
sli hasnt really been interesting since voodoo2 sli...

that was back when we desperately needed the performance.


no one needs sli with two modern high end video cards.

period.

Ever tried running a 30" LCD at native resolution? Even 24" LCDs can use SLI/CF. So people that want to spend $1000+ on displays probably like getting $1000+ GPU setups.

BTW, CrossFire does work without a dongle on lower end models (X1300, X1600). However, I tested X1600 Pro CF and found it to be totally underwhelming. It about matched the performance of a single 6600GT, and boosted performance a maximum of about 50% over a single card. Apparently, the extra BW *is* needed - X16 PCIe isn't sufficient... or the drivers need work.

SLI also works without a bridge at a small performance hit
