[videocardz] AMD to launch 300W GPU with High-Bandwidth-Memory - Page 18

post #171 of 772
so it uses the same amount of power that a overclocked 780 or 290 uses hopefully amd made a better cooler to go along with it if its true smile.gif

my gtx 580 used about 300w but it had a 3 fan design cooler so it never went over 50c so aslong as amd makes a good cooler for the card i dont see it being an issue smile.gif

Really all we should care about is performance per watt. If its 300watts and its 30% faster than a 980 .. and i have not done the math but i would think its on par or close for efficiency with GM204.

Heck i'm running 2700 watts of PSUs at present to power 2-3x780 TICs . They can pull over 500watts each. In games i've hit 515 watts per card (heavy oc). So 300watts .. this is not an issue for me at all.

Just as long as AMD water cool it out of the box this will not run hot i would think. Nobody in their right mind would air cool this card .. GTX480 / R290X issues all over again.

Everything is trying to reach an equilibrium on a temp in your room. if you pour 1000 watts of energy into the room the temp will go up the same amount.

Visual reference: If you pour 16 ounces of fluid into a cup, it doesn't matter how fast or slow you pour the liquid, you will still end up with 16 ounces in your cup once you are done. Same holds true for heat energy added to a room.

All of the heat generated will get transferred into your room eventually, in this case any sort of difference between a water cooled and air cooled system the difference in room tempature would be insignificant if the time scale is more than a few seconds. The heat generated will be a watt or two more as the system runs hotter, but that's less than a percent of the heat generated, which isn't going to make any real difference.

This is definately too much heat for my mini Itx build, I am sad now.

If it's hot open a freaking window lol. Why ppl argue like as if they lived in a matchbox?

Ummmmmmmmm.

300W? So...28nm?

Didn't AMD already go on record stating there wasn't a larger more powerful 28nm product? Wasn't it just a few months ago that there were rumors that the 290X was actually a cut version of the full blown design, and a new FULL card was coming? Yet AMD came back and said that wasn't the case and they had nothing beyond 290X for 28nm.....

Pretty damn sure that happened.

So if this isn't 28nm, but is 300W......20nm @ 300W = Big ass card?

Forgot to add ez-bake oven to your PC function list.


i have never w/c a GPU before. if it came with an AIO attached, i think i would definitely upgrade, then.

Well, you guys can call me ignorant, stupid or anything in between. I've water cooled plenty myself in the past, and if anything I felt it made the room get hotter. Obviously we're not talking 10C, here.

JayzTwoCents has been water cooling for over a decade, and at 8:50 of this video, he states the exact same thing. You gonna get ahold of him and tell him he's unimaginably ignorant, Mr. Brain @Dmitriy?

And your 16 ounces of fluid in a cup is a great analogy and all if every bit of heat is trapped in your room like every bit of fluid is trapped in the glass. However, this is not the case.

290X was fully unlocked, new cards are 28nm as well but using a different process to make them though which is supposed to be just as good as dropping it to 20nm. Called SOI-FET or something like that. I don't know you are gonna have to ask someone else. Anyway it's supposed to have a new architecture as well so the only thing that's going to be the same is the die size itself. Still all rumors though and I'm only parroting what I've read others who know more than me say.
