More RV560 and RV570 details
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
compatibility with CrossFire capable motherboards. Dongle-less CrossFire will not move all data across the PCI Express bus however. Motherboard manufacturers told
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
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.

Is it just me, or does the ATI solution appear to require TWO bridges in that picture? Is an nVidia-style bridge not wide enough to handle the data?

It's their own proprietary interface. They can decide how much pins it require, it's not the sli interface and it's not following any standard. However they could just use the pcie interface since it has a huge amount of unused bandwidth, I know they can do this since the X1600 can do crossfire with no dongle/bridge.

The bridge should increase bandwidth and decrease latency.
