55nm R680, RV660/670, RV635 & RV620 In Q4 2007

According to our source, AMD's latest roadmap hints at all next-generation GPU's being based upon a 55nm process.

all next generation GPUs will be 55nm based even for the highest end GPU supporting DX10 Unified Shaders, Crossfire, HDMI, HDCP, UVD and PCI Express 2.0. R680 will be the successor to R600 for the enthusiast segment slated for launch in end of Q4 and mass production in Jan 2008. There will be UVD for R680 this time round. There is a new performance segment with RV660/670 while RV635 will succeed RV630 for the mainstream segment and RV620 to succeed RV610 in the value segment. They are slated for sampling in Sept while mass production in Jan '08.


One initial question pops into mind though...why the weird node size?

Hey guys just asking what would be best for my system tygon or dd flex

system so far:

xspc res
D5 vario
D-tek fuzion
2x EK 8800gtx Delrin
pa120.3 then back to res
also would it be worth splitting the tube from the first rad with a Y or T peice to go to the cpu and gpus then joining it to go to the 2nd rad

I would personally go for tygon but that's just on looks ;)

No I wouldnt bother with a Y piece, you will not be gaining as much as if you had the 2nd rad after the first block

Cant you do a double loop? I would go for tygon it has very thick walls.

dont know if i could do a double loop will have to check what space i have left after the first one but maybe could be a possibility thanks

and to llwyd do you mean

reservoir to pump
pump to cpu
cpu to twin rad
twin rad to gpu's
gpu's to triple rad
then back to the rervoir

Res > Pump > 120.3 > CPU > 120.2 > gpu > gpu > res tbh

I really doubt you will see any performance increase by adding a third rad as your flow will just die completely

07-06-2007, 17:55:18

if it was me id go

Pump > Res > Cpu > 120.2 > Gpu > 120.3> Pump

if you have room for a 3rd rad then get a 2nd pump instead as the increase in flow will give more than another rad
