^^That graph shows only the inaccurate measurement on Xbitlab's side,nothing else(as for the higher than official TDP for AMD)

And BTW ,this is OFFTOPIC!

btw: the x2900 cards should came with 8 pin adaptor ;)

I will be very interested in seeing this adapter :)

Ahh... only a few more days now!

Well my GTS is going on Sunday so hopefully I will have one of these on Tuesday or Wednesday if the price is right.

What isn't?

The TDP is just a design envelope indicating the upper thermal dissipation needed for a chip/card. Overclock or overvolt and it will move beyond this design envelope. That's my point. For Intel the main issue is when Tc >Tc-max. Take the C2D E6600 has a TDP of 65W, the same across the range except the 75W extreme versions. Its just a thermal generalization for the chip package, think about it, a 6300 should be lower than 6600, its not. Its really there for Engineers to design cooling solutions in the real world. Its not that accurate a reflection on maximum wattage. The Intel value is certainly not an average, more like the typical maximum (stock). AMD? Well its supposed to be the maximum (stock). If you're saying they under report it, I wouldn't know, its hard to measure. Theoretically if you ran identical systems the power delta should be the same as the TDP difference, but then you get into internal/external memory controllers and chipset efficiencies. I wouldn't place to much stock in charts.

Sorry for the OT

Very good news...meaning AMD users with 3ghz rigs will be able to get 12k-13k scores with an oced HD 2900 :)

Check out the ghetto cooling. Love it.

Holy crappola, it's doing 1000/1000 on air :eek:

R600 can't walk on water but it sure can fly and with the 357€ that has been seen on some site already to my surprise i am even considering crossfire in a not so distant future, DAAMIT :devil:

It's better to invest in watercooling than to invest in crossfire for now...OR

If you are bent on buying two cards, wait for the XL...two of those will be more nominal with similar performance.

It will be a little more than 320mb price range but still retain the 512mb gddr3 of the XT.

How does that score stack up with the 8800GTX?

Perkam dude, i just can't pass on the 2900XT, it's gonna be cheaper than what i paid for a 1800XL, perform like a champ and OC like crazy (if retail is the same than press samples). Too sweet a deal :D

I aggree... Cant wait to see what 2 of these in crossfire on a x38 chipset is gonna do....:cool:

You can say that again... For what you get its an incredible price.

Agreed.

what's the difference between GPU TDP and Board TDP ?

so the R600's(GDDR3) power consumption is 160 or 225 ??

and G80's Board TDP is 225W too , no ?
05-08-2007, 06:47 PM

Board is the total power for the entire board. Gpu, ram, and other various chips.

The 8800GTX is 175-177, I can't remember which, total.

so the important thing is the Board TDP not the GPU TDP ?

12k is at stock with a stock QX6700. ;)

Oc'd, plenty of room for higher with 8.37 drivers.

The 16k ss shot from VR-Z I reckon is a QX6800/QX6700 at around 4GHz.

GPU TDP gives a general idea about core temp, so it's still very important.

Knowing VR-Zone, I'm thinking much higher than 4 ghz on the quadcore.

By measureing it before the VRM. Thats also why 1 CPU looks to be out of spec.

It's always good to read the article one quotes.

And your point being? Its the same thing. And I´m quite sure we can assume a somewhat equal efficient VRMs. So making all numbers alittle lower would what? Change anything, not really since the point was it had LOWER TDP! :slapass:

So counting the loss in the VRM just makes it even better. :fact:

Are we still under the impression that May 14th is the date?
