Urhhh .. GDDR4 at 3.2Ghz with 0.6ns access time anybody!!!

Samsung Electronics, the world?s largest maker of memory, announced that it had developed GDDR4 memory chips that can operate at speed of 3.20GHz, nearly two times higher compared to memory frequency on today?s graphics cards.

?With such phenomenal processing speed, we?re able to offer video card manufacturers the bandwidth for incredibly life-like movements and richly textured imagery that will soon rival that of cinematic movies,? said Mueez Deen, marketing director, graphics memory and mobile DRAM, Samsung Semiconductor.

The GDDR4 memory chips with 0.6ns access time capable of working at 3.20GHz resulting frequency are made using 80nm process technology and have 512Mb capacity. Late in 2005 Samsung introduced 256Mb GDDR4 chips rated to work at 2.50GHz. Voltage and heat characteristics were not touched upon by the company.

GDDR4 memory is intended for graphics sub-systems and other multimedia-oriented devices that require high-speed memory and can use point-to-point memory interconnect.

It will take some time before developers of graphics processors and their memory controllers will be able to utilize 3.20GHz memory, as GDDR4 final spec is yet to be ratified, whereas graphics chips are usually tailored for particular range of memory speeds.

Market watchers predict that sales of graphics chips will reach $2.7 billion this year, up 10% from $2.5 billion in 2005. Further, the graphics DRAM market is forecast to grow 27% year this year to $1.9 billion from $1.5 billion, Samsung indicated.

Sweet!!

I thought Ati said r520/580 supports GDDR4? That thing runing at 3.2 ghz would kill everything in its way:Q

That's a lot of bandwidth! :Q

Sweet jesus.

 

[evenmore1]

Oh wow! Can't wait to upgrade my PC!

 

[RichUK]

Guess nobody is that interested in what will be on their future Gen nVidia and ATI cards.

 

[StrangerGuy]

Screw video cards. I want them with CPUs!

 

[JAG87]

rich, its needless to post. every1 is impressed.

 

[thecoolnessrune]

WOW. I mean darn. Kicks the crap outta my GeForce 4 MX 420 with DDR 2700 or my 440 with DDR 3200 :laugh:

 

[Dainas]

Samsung is still king it seems.

No, their MEMORY CONTROLLER supports it. That doesn't mean that they have the necessary logic, power, and what not onboard. I wouldn't count on GDDR4 until AT LEAST G80 R600. Perhaps even later than that.

Yes i was thinking much later than that Gen too.

They probably can get GDDR4 working on X1900s. The board vendors may have to modify some components but they should be able to get it, if the memory controller supports GDDR4. Never know.

Oh, well, maybe not.

I think I read something about it being published at the ISSCC. Now, I know most of you aren't EEs, but papers presented at the ISSCC are usually (actually almost always) well beyond what can be commercially produced at the moment. The fact that they demonstrated it is interesting, though it will probably be at least one GPU cycle, but more likely two or three cycles and one process shrink before they can be mass-produced. Typically, papers presented at the ISSCC will show technology at least a year or two before they are commercially viable with reasonable yields.

GDDR4 i believe isnt really necessary yet,

GDDR3 still has a ways to go in ns refinements, and possible shrinks no?

and most video cards are not memory bandwith limited...

I can't even afford this gen. of graphics cards. I'm waiting for whatever comes out next gen. to cause this gens. cards' prices to drop enough that I can afford one.

That's what I was going to say...this won't really be necessary until cards are memory limited again...

wow...its insane....

however point is true that GDDR3 is still young, however SAMSUNG definetely deserves a w00t for this!
