QUOTE(jinaun @ Dec 16 2007, 04:31 PM) its embedded into the GPU with total bus width of 2560-bit (composed of three independent buses: 1024-bit write, 1024-bit read, 512-bit read/write) working at 8 GHz Haha~! If only it's true...Guess it's going to take a 12nm process or smaller for that to happen. Now that'll be cool   [attachmentid=360983][attachmentid=360985] The blue squares are where the GDDR3/4 are supposed to be. This post has been edited by clayclws: Dec 16 2007, 05:00 PM |

I wonder if it's worth the wait...January ain't that far...but 31st January is still January...

I'm worried about the GDDR3 usage...it's not as energy efficient or OC-able as GDDR4. They've used GDDR4...why are they taking a step back for their flagship product? Hope it's not accurately reported.

QUOTE(jinaun @ Dec 17 2007, 11:09 PM) perhaps GDDR3 is much cheaper.. and clock for clock.. is faster than GDDR4 due to additional latencies associated with GDDR4 Hmm...I have never seen such thing happening in the Graphics RAM department before. I always have the impression that GDDR4 is a better spec-ed GDDR3 - an improvement in energy efficiency, increased official speed, etc. In other words, it is like Vios 2007 compared to the ordinary Vios. I guess I better go dig up more from my friends and web.GDDR4 will onli be faster than GDDR3 if its clocked high enough.. eg.. take DDR400 vs DDR2-400 |

QUOTE(ikanayam @ Dec 18 2007, 01:01 PM) Looks like you probably didn't read what you linked to. GDDR4 saves power and clocks higher not by magic, the internal memory elements are clocked at half the speed of comparable GDDR3, so latency is higher. My bad. Bad reading comprehension. Was looking for the advantage bits only.This post has been edited by clayclws: Dec 19 2007, 06:45 PM |
