SAMSUNG GDDR4 Memory Selected by AMD for the Radeon HD 2000 Series

[malware]

Samsung Electronics announced today that its 80nm GDDR4 high-speed graphics memory chip is being used in both the 1GB ATI Radeon HD 2900 XT and the 256MB ATI Radeon HD 2600 XT graphics processing cards. The 1GB card has the widest bus in the industry designed for full-performance, high dynamic range (HDR) rendering in PCs.
We chose Samsung’s GDDR4 memory for our 1GB ATI Radeon HD 2900 XT and ATI Radeon HD 2600 XT graphics cards because its design complements our strategy in offering leading-edge technology to a broader enthusiast gaming market said Vijay Sharma, Director, Product Marketing, AMD Graphics Products Group. Samsung’s GDDR4 memory devices are now in mass production and will appear widely as soon as the new ATI graphics cards hit the market.

HD2900XT F1 edition? :laugh:... The HD2900XT was really bottlenecked by the memory anyway so this is a nice change.

It's a nice move but this may only cost you more in the end. IMHO this card with a ATI Tool may in fact be a serious competitor...
Samsung’s GDDR4 memory devices are now in mass production at the 512Mb density level.
Is this what I think it is? :confused:

Good thing Im waiting. Id love to get one of the 1GB DDR4 2900 XTs.

[yogurt_21]

damn anybody notice the .6ns, thats 3GHZ rated!

[hv43082]

So the main question is: Will it be faster than 8800GTX?

lol.. soon as i get atitool working.. ill let ya know if i manage anything near to 3ghz :p

edit: wonder what would be a safe voltage for these chips?

i know i know.. its killing me.. with everything stock i managed just over 10k in 3dmark 06, now im even having problems getting 3dmark to run since i reformatted my pc the other day. it hangs on the 3dmark loading screen. WHY HAS SOME EVIL DIETY CURSED ME SO!!

I even had one boot where atitool ACTUALLY WORKED, then never again.. think it was to drive me insane, coz it happened just b4 i had to leave for work, when i got back it was a no go :(

C:\WINDOWS\system32\Futuremark\MSC and rename the file "direcpll.dll" to anything you desire.

.6ns @ 1.6 GHz = 3.2Gpbs

GDDR4 costs the same to manufacture.

Actually no they do not cost the same. Current HD 2900XT 1024 cards are using BC09. The BC06 are the low yield and expensive compared to the BC09 currently on the video card.

Eastcoast what do you know of the overclocking potential of the gddr4 ram chips?, you appear to know a fair bit about them :)
