2 is better than 1 - we have got ATI and NVIDIA both touting this – in fact soon we will have ATI telling us 3 is better than 2 - and NVIDIA have already played their hand and told us they want atleast 4. With this in mind the way that you deploy your next multi-GPU solution is becoming critical.
Currently ATI have some cards which are "dongle less" - now up to the X1900GT. However, the ATI RV560 and 570 which are replacements for ATI's mid-range parts will both of course support Crossfire. Nothing new I hear you cry, but wait, the challenge ATI currently face is the way they get the 2 cards to connect. Here is the real juicy bit - ATI have too much data which needs to be pumped between the 2 to go across the mainboard so they have to bridge them. No one likes the ATI dongle - it's deemed a 2nd rate solution compare to the NVIDIA internal connector. ATI have finally decided to follow suit and they will launch the card with 2 connectors inside, these dual connectors will push data both ways.
So, have ATI copied NVIDIA again? Care to comment in the HEXUS.community
