5870 X2 TDP is 376W

[Tempered81]

Well if you clicked on the link in the post you quoted, you would have seen it at 210 watts....

well then max load would have to be around 150watts on 5870 if true

Just average load wattage would have to be around 150. A 4870 can pull as much as 210 watts by itself, and they had no trouble X2'ing it and average 260w load...

All I can say is those numbers are not valid in the second link. HD 4850 pulls 147W? The theoretical max is 150W and I doubt AMD would have released it with only one pcie connector knowing it would use close to it's limits. The Xbitlabs numbers are closer to reality.

The second link IS xbitlabs, so Im going to guess you mean the first link is "not valid". Note that by calling out xbit and TPU as not valid, you are calling W1zzard and Anton incompetent, while listening to fudo. Here are all the graphs, and yes the cards pull well over they're rated TDP when peaking at maximum values. You can measure the card at idle, 2d, 3d load, 3d peak, and maximum. I don't understand why anyone would want to second guess this data for a minute, the only one shooting smoke up everyones ass are the rumor mill sites (like for example Fuad with this 5870x2 TDP goofy article) The two graphs are to represent that even though a 4870 has a tdp of 160 and an idle of 80 and a load of 130-140, that a 4870 can still peak at ~180-190, and max at 210 or more watts. A 4870x2 has connections for a rated 300 watts of maximum power, however it has been observed many times pulling well over 375 watts when peaking or reaching maximums. Those figures arent sustained for any relevant amount of time.
The 5870 can have a max of 180-190 watts (which is identicle to the ratings of the 4890, and slightly higher than the 4870) and it can achieve much higher maximums than 188w. It also likely operates at full load at an average of 140-160watts......

Anyways, I'm not sure what you're calling invalid but here are the rest of the charts:

Idle: Windows Vista Aero sitting at the desktop (1280x1024 32-bit) all windows closed, drivers installed. Card left to warm up in idle until power draw is stable.
Average: 3DMark03 Nature at 1280x1024, 6xAA, 16xAF. This results in the highest power consumption. Average of all readings (12 per second) while the test was rendering (no title screen).
Peak: 3DMark03 Nature at 1280x1024, 6xAA, 16xAF. Highest single reading during the test.
Maximum: Furmark Stability Test at 1280x1024, 0xAA. This results in a very high non-game power consumption that can typically be reached only with stress testing applications. Card left running stress test until power draw converged to a stable value.

The xbit link shows a 4870 pulling 130 watts at load (4870x2 pulling 260w), even though its rated at 160w and can obv reach 210w in furmark (well over it's designed specs)....I hope this isn't confusing.

edit: BASICALLY here is what I'm saying is funny: 4870 TDP 160W 4870X2 TDP 280W, FUDO Sees 5870 TDP 188W, thinks 5870X2 TDP is equal to 5870 TDP times two (When it isn't) and people believe him and create controversial discussion. 4870X2 TDP is not 4870 TDP times two, why would 5870X2 TDP be 5870 times two...

This is just ROFL stupidity.

So you believe it is about 330 watts? Sounds reasonable and can use two 8-pin connectors but it will need a damn good cooler. In Furmark then it will use 380 watts or more and even in a perfect case it can't be run for more than a couple of minutes. They will need to put a DO NOT RUN FURMARK OR WARRANTY IS VOID sticker on the box. lol A triple slot cooler will need to be considered for something like that or at least a dual fan- one over each gpu.

well the 4870x2 uses TWICE the power of a single 4870 http://www.xbitlabs.com/articl...hd4870-x2_6.html#sect0

It appears that Xbit Labs is using the 512MB version of the 4870 in those tests. The 1GB model (i.e. 1/2 of the 4870X2) will consume more power. I don't know what those numbers are but the X2 would use less than just doubling the power consumption of the 4870.

In bold ^ .. Please don't say things like this anymore. It can't be an "isn't" when it "isn't" even an "is"!!!
These cards are not "past-tense" yet. So, we can't know the TDP for 5870X2. Not for a couple of months yet.

Bingo!

Comparing maximum power draw for hardware is like comparing maximum gas usage over time for cars when they are going their top speed, noone does that because it doesn't really tell you anything meaningful.

For cars we have MPG for a comparison that is at least apples to apples, I wish someone would take a go at a similar comparison for CPUs and GPUs.

I for one DO NOT CARE if the power consumption is a little high, as long as it is within reason for the performance I'm getting. People don't balk at buying 850-1000 watt power supplies. hmmm, why? Probably because they are expecting to buy POWER HUNGRY hardware.

If you are buying an hd5870 x2 or whatever this thing will be called I'm sure it isn't going in an netbook grade pc,

376W is not 'a little high'!

Theres no way they will release a card that uses above 300W.

I'm sure somebody said the same thing about 200W some time ago.

True, but I still don't think they will release a card that uses above 300W.

I wonder how much my PC uses at full load (c2q and 8800gts), probably under 376W.

 

[WelshBloke]

And to follow on from my last post.....

wheres the power coming from?

8pin plus 6pin plus pcie2 slot =300W max

even if they are mad enough to put two 8pin power sockets on there it wont come to 376W.

And they aint gonna use an external power brick. :laugh:

 

[imported_Shaq]

It would be enough for 375 watts, and if the actual TDP is closer to 330 watts there is enough to spare.

 

[v8envy]

Depending on how much of a premium ATI can get from the x2 cards they'd have the option to cherrypick 5870 cores able to run at target clocks at a lower voltage. Tadaaa! 300 watt target achieved, even though consumer card power usage may vary up to 188 watts.

They didn't need to do that with the 4870x2 because the card already fit under 75 watts pcie + 75 watts pcie 6 pin + 150 watts pcie 8 pin budget.

 

[imported_Scoop]

Btw, TDP is not power consumption.
