GDDR3 and GGDR5 but where is GDDR4?

Today we always see either 3 or 5 buy why never 4? where did it go?

 

There was actually GDDR4 for quite some time, it kind of hung around for a while, but died out with the introduction of the Radeon HD 4000 series, as the high end cards in this range came with GDDR5. I don't think any NVIDIA cards ever had GDDR4, but some Radeon and MR cards did. I think the old 2900XT came with it - if it wasn't the 2900, then it was probably something a little more midrange.

There is also a variation of the Mobility Radeon HD 3650 (incidentally the card that happens to be in my notebook) that came with GDDR4, but I don't think any manufacturers ever used it. If they did, it was fairly obscure.

I assume some other cards in the 2000 and 3000 series also came with GDDR4.

 

Looks like the x1950XTX, HD 2600XT, and HD 2900XT were the only ones.

RIP in GDDR4

 

Sapphire did release one model of the 4670 with GDDR4. GDDR3 speeds could get close to GDDR4 at times (that particular card had memory at 1100 MHz), and GDDR5 of course offered up twice the bandwidth, so GDDR4 was kind of unneeded.

 

GDDR4 was very, VERY power hungry and was not much faster than GDDR3. Therefore was a bit of a failure. Certainly not for laptops.

 

GDDR4: The Vista of Graphics Memory

 

You mean the Windows Millennium.

 

Not the only ones. It states on AMD's site that there was an iteration of the MR 3650 and 3670 that came with GDDR4.

 

I like Vista.............I'm almost compelled to buy a copy of Vista 64 so I can have my Windows Media Player mini-toolbar back.

 

Sometimes I find Vista to be better than 7, and both definitely a step up from XP.

 

How the heck did we manage this, lol?

 

i agree with u on being better than XP but IMO windows 7 is better and more stable.

 

in my personal experience, Windows Vista was faster then Windows 7. I get alot of hiccups and freezes with Windows 7 that I never had with vista. Makes me want to go back. And I liked the way UAC was in Vista

 

Only GDDR4 Video I know off.

 

Exactly what I've experienced on my personal notebook (Acer in sig), though my gf's Win 7 notebook is stable as ever. It's probably just a certain combination of factors that aren't interplaying very well.

 

Hmm...

I'm happy to acknowledge that Vista isn't nearly as bad as it's historically been made out to be, thanks to its rushed release and poor early driver support, but from the moment I switched from Vista to Win 7 RC1, it was Instant Joy Upgrade +10 for my lappy, and the real thing is even better.

And to keep things slightly on-topic - I'd always wondered about GDDR4 as well, so I'm glad that's been answered.
