Literally 280's with 2/4GB vRam. Same amount of stream processors.
Not sure if its Hawaii/Tonga.

>TDP 375W
Damn ...

that 375 watt better be a typo.

Why has not that person with XFX card on hard forum posted results of power consumption, or anyone have shown interest?
It's what im itching to know if this 'enhanced Hawaii' means anything, which must mean they have made suitable modifications, but what is reasonable to expect that they may be? Support for freesync?

From what I have seen the people that have these cards for the most part are not willing to share much or post much other then an initial screen shot for..hey see what I just got. I had to beg and plead just to get a bios and even that I had to settle for the 390x one.
But yeah that 375 watt blew me away...hoping it is an error.

My pessimistic side says they'll only be binned and that stupid true-audio ****.

Was just thinking about the 375 power consumption they listed.
These cards have 2 x 8 these Pcie cables can draw a max of 150w per cable so 150w + 150w =300
The Pcie slot can draw a max of 75w
So 150w+150w+75w= 375watts
Therefore it seems a shortcut for them but they just added up the max possible wattage draw based on the pcie specs not on actual testing. If this is true this is sloppy or they will be changing it on the 16th.
This is all true if I am remembering and understanding today's pcie specs.
CalculuS
Good observation, seems pretty likely.

Someone already mentioned it another thread:
2x 8-pin + PCI-E = 2x150W + 75W = 375W
So I doubt 375W is really its TDP, but rather how much power can reliably be drawn from PSU.
Reliably being somewhat vague term, because electrically it can sure draw even more, but even with 2x8 it's out of official PCI-E spec.
Not that we haven't seen 2x8-pin gfx before.

EDIT: I was referring to mtrai's post
Fox2232
Can you use VBE to check actual TDP limit?
mtrai
I have tried opening the bios in every tool I know of. I could only post what I was able to read from hawaii info, memory info and what GPU-z reported with the bios on my 290 non x. Sorry.
I really can't make head or tells much in hex editors.

I really don't give a crap if a card pulled 500W, if it meant an uber fast single card solution.
CalculuS
We're getting that number pretty closely with the 290x if its a linear increase.
Btw is there already a PCIE connector that can give more than 300W combined?
Aside from molex.
mtrai
While not scientific...as it seems hard to get people to really test the way us techno-geeks do..while not acurate it will give us something to go off of.

Nice to see some more info. Seems they have improved a little bit at least. Am I wrong or would not a reference 290x be using above 300W in an intense stress test like furmark?

oh look 205w, omfg 300 or even 375w, panic mode on!! 😀
Its not like you pay millions extra just because it may have a little extra power output.
What about all those household gadgets? a freaking hairdrier or vacuum cleaner can have 1500W, nvm other stuff like fridge, dishwasher, microwave.. In terms of power consumption.
Also a quality PSU silver or gold 80+ with enough Amps won't have any trouble dealing with 375W power, for example +12V 750W psu rail is 2x more then pcie standard.
mtrai
At first the way it looked here in this case was them saying it was a 375 watt draw...which could really affect what PSU you you need. I tried to to debunk the 375 watts issue, but still at this point we cannot say what PSU you have to have based on specs we have seen.
So in short we are looking at PSU and will it work. Perhaps you misunderstand.
mtrai
Have you ever tried to power a hairdryer off a PC PSU? Get real.

I used to think like that before but not anymore. When I had 290 it actually did make my room (especially near my computer) noticeably hotter which wasn't that nice. In full load the heat output was so big that even MSI's Twinfrozr cooling didn't quite keep up thus making it noisier and hotter than what I'd like. Especially if overclocked.
