QUOTE(popopi @ Dec 13 2007, 06:10 PM) then the difference between DDR3 2000MHz and DDR4 1100MHz ... which is better? get this from sapphire 3870... not sure where i found already. higher MHz is better? or better DDR version better? See those bold parts? Let me explain something for you. People list down things as they want...even those price list that you see. GDDR3 (not DDR3 - G stand for Graphics) has a rated speed of 1000MHz. At Double Data Rate, it is rated at 2000MHz. GDDR4 (also not DDR4) has a rated speed of 1200MHz. At Double Data Rate, it is rated at 2400MHz. So what you read is wrong...typo or marketing ploy. GDDR3 will always be at 1000MHz (2000 DDR) or less (JEDEC Standards and not OC types) and GDDR4 will always be at 1200MHz (2400 DDR) or less (JEDEC Standards and not OC types). |

QUOTE(ronho @ Dec 14 2007, 08:43 AM) bro clayclws, you mean DDR3 > GDDR3 ? sorry didn't see it in the links.... We always use the term GDDR3 for Graphic Card's memory. DDR3 are more towards computer memory (Ram). They are basically the same thing. The "G" only indicates that it is for Graphics.  |

DDR3 has better specs than GDDR3. Compare the specs.

Just trying to enquire a confusion here that i have. I mean, many pricelist/suppliers out there are stating eg. HD3870 DDR3 ... but it was suppose to be GDDR3 right? This is because, i always have an thinking that there is no such thing as DDR3 for GC because the correct term that should be used was GDDR3 and to prevent confusion for some buyers, they just renamed it to DDR3 as it is similar to the RAMS. Correct me if i am wrong though.. |

Correct me if i am wrong though.. Yes you are right. DDR3 is for CPU. GDDR3 is for graphics as I pointed out earlier that the G stands for Graphics. DDR3 has specifications better than GDDR3. JEDEC had wanted to incorporate GDDR4 specs into DDR3 but, well, as you know, GDDR and DDR has different...erm, let's call it architecture...different architecture. |

QUOTE(Createmous @ Dec 14 2007, 04:46 PM) explain more. Which? The DDR3 vs GDDR3 part? I've explained that. R680? I don't have much info. I post it up so that someone that is better informed could start a new thread on it. You could look around the web for lots regarding R680. Even the "leaked" pictures are available. |

QUOTE(Createmous @ Dec 14 2007, 04:46 PM) explain more. From what i can see from the site, its more like a new 55nm version from ATI that has 2 GPU in one GC. More like crossfire in one card by itself... |

Indeed it is. 2 cores on a single PCB. I don't know how they Crossfire or whatever that they are doing though. The scalability of performance would probably be similar to two HD3870 running in Crossfire...but I wouldn't rely on that.

QUOTE(skylinegtr34rule4life @ Dec 15 2007, 12:53 AM) 2 cards integrate 2 one just like the 7950GX2 which was a big failure?   7950GX2 has 2 cores on 2 PCBs being connected through SLI and being sold as a single card. R680 has 2 cores on 1 PCB being connected through some kind of Crossfire. But that's not confirmed yet... |

GX2 is SLi-ed 2 cards occupy 1 PCIe and if SLi 2 x GX2 become 4 way SLi...? then i don see any reason for 3 way SLi to waste such space and power...  It seems tat ATI might be the 1st but the idea goes back pretty far behind since Gigabyte's 3D1... or further back... but i got this...
