GDDR5 samples ship out
QIMONDA HAS BEGUN sampling GDDR5 to selected partners, the firm has said.
Graphics cards next year will almost certainly hit the market with the latest memory technology, which is set to be faster and lower power - as is customary with each new memory revision.
New to GDDR5 is the concept of cyclic redundancy checks, long used in comms and storage technology. Since there is so much data traveling through the extra bandwidth GDDR5 brings, checking it for consistency appears to be a key requirement.
Qimonda reckons that there will be a 3x improvement in performance over current GDDR3 memory, and bandwidth will be up to 20GB/sec. Crucially, the spec supports simultaneous writes to multiple modules, opening the possibility of parallel writes for extra speed.
GPGPU freaks will be spooging over this one - as, apparently, will Intel engineers. Rumour has it that the first chaps to get their hands on samples with be the Chipzilla bods working on Larrabee. µ

I thought these gimmick names were supposed to be anagrams. Maybe it is, I'm just bad at them.
DDR & DDR2 wern't that differnt in performance, Single threaded is almost same as double. However, Each is improved technology. it appears Gddr4 to Gddr5 is less than doubled, yet it is better. 20 ghz/sec in data thru put is lot o' subsystems in dee ole gp gpu circuitry.

Until next step each improvement is very nessessary step & gddr5 sounds like FLYER.

learn to read you idiots, its about GRAPHICS DOUBLE DATA RATE, not just standard DOUBLE DATA RATE...
dude, stop signing your comments "PHYSICIAN THOMAS STEWART VON DRASHEK M.D. "

you're not a doctor. you type like an imbecile. no doctor would sound that stupid and unreadable.
First off I want to start off by saying that reading the "INQ" is a daily religious routine. Thank INQ. On topic what is the deal with these mem companies, DDR4 is still not right yet they want to go ahead onto DDR5 development? Thats beyond me.

Quimonda views GDDR4 as a niche product that won't really do much in the market because it offers too little improvements and decided to skip ahead to GDDR5, read about it in this EEtimes interview:

Titled: Aiming at high-end graphics market, Qimonda skips GDDR4
It makes sense really, it's costly to set up manufacturing and if the market needs faster stuff sooner than later the lifecycle of GDDR4 can't be that long, and if GDDR5 is defined already why not skip to it?
GDDR and DDR are different standards. The "G" in GDDR stands for graphics. Please stop mixing these things up, they are optimized for different workloads(ie. graphics vs general computation).

So to the poster above, it is not DDR3 to DDR5, it is GDDR4(already in market in products such as ATI's x2900) to GDDR5.
OOPS! My bad I meant to use GDDR4 not DDR4, dont flame me. Anyhow I do realize there is a difference. The only comment I was trying to make was that I know that GDDR4 is not finalized/optimized yet. It uses more power than GDDR3 and its slower, but GDDR4 has more bandwith thats it. To the jerk that said we need to read better, stop being a Dik.

I'm pretty sure PHYSICIAN THOMAS STEWART VON DRASHEK M.D. is a talk bot. Surprisingly, he's actually making a modicum of sense this time.

What, by saying that each improvement is a necessary step until the next one? :) Some of his stuff is so "unintentionally" funny I'm beginning to wonder if someone is pulling our leg.
