Radeon HD 7000 is 384-bit

Written by Fuad Abazovic

High-end SKUs, of course


On top of the new 28nm manufacturing process, courtesy of TSMC, AMD’s new HD 7000 series will also feature other exciting novelties.

We have learned that high end Southern Islands parts will feature a 384-bit memory interface. We‘ve already told you in that the memory of choice is GDDR5.

Naturally some mainstream and entry level parts will still feature a slower, cut down version of the memory engine, due to necessity for lower TDPs and production costs, but most of you know how it goes. Some parts end up with 384-bit memory, yet others, like mobile GPUs for example have to make do with 128-bit. Fewer bits translate into lower TDPs and cheaper cards.
 
Our sources are still telling us that the official launch is early next year and only rebrands will make it to this year, not the actual 28nm parts.

Lets see about that rebrands.

It was long time ago since we saw ATI/AMD doing more than 256-bit...

IF this is truth lets hope it doesnt end like 2900 XT.

very true mate,very true :D +1

IF this is truth lets hope it WILL end like 2900 XT.


Fixed - since it wont be any different than 2xxx and 3xxx series failures.They already cutting all tech from those cards,first Rambus,next? Price - cant wait till amd fagbots start they usual price/performance BS (we all know amd just CANT make fastest single gpu LOL)
Looking forward reading some funny amd fagbots "comments" as usual :baby: LOL

Hi Warrior.

Interesting this will be their first mega chip since the end of the R600 (2900xt) and their second ever. A mega chip is a gpu with a physical memory path greater than 256bit and has a die larger than 400mm2. Expect this card to run rather hot and use a lot of power compared to what most people are used to as far as ATI cards go. Will be a good solid performance card for what may be years to come.

Nele you must be the must incompetent moderator in the world. Do you ever read these comments? Whats the point of even having this comment section if its just a fanboi trolling zone? This dude has been spouting his bullshit for 2 weeks totally unchecked.

Not necessarily, we don't know a lot about those chips, clocks, voltages, and how they work internally, but from what I've seen at S|A, they mean to gate shading units so if a games doesn't make use of them the TDP will be lowered.

I'm not a moderator at all, although I admit I would probably be an incompetent one...

Anyway, he's gone... :lol:

Also, we're looking for moderators. Fanboys need not apply.

Would a high 384 bit bus necessarily require a 2slot AIB? Will there be any high-end single slot HD 79## or HD 78##?

Maybe with water blocks. High-end GPUs haven't been one-slot cards in a long time. A one-slot cooler just isn't good enough when the chip is outputting >150W (sometimes more than 300W). It's entirely possible that they could make a chip with a 384-bit bus that dissipates less power and can use a single-slot cooler. However, this would be dumb as the shaders wouldn't crunch numbers fast enough to actually use the bandwidth of a 384-bit bus.
