What does it matter where it is pulling the watts from? Be it the pcie slot or the connectors it is still 300w of roasty toasty.

Id rather have a 300w tdp card instead a 220w but with the same watt/performance ratio as the 7970 and a nvidialike capability of overclock. Hello 8+8 designed pcbs biggrin.gif

Yeah, I mean the 7970 is just such a crappy oc'er... oh wait.

Be interesting to hear the actual reasoning for such a high power capacity. I'm hoping that it is an actual lower TDP with lots of headroom. A high-TDP card is not what we need right now. We need some really good competition from Nvidia to drive down AMD prices a little.

Kind of odd that its GK104 especially seeing as its nvidias smaller die (around the same size as Tahiti). Worth noting also:

With AMD, TDP is absolute maximum power draw at +20% powertune which it typically never gets close to reaching. For example, 7970 TDP is 300W, but during gaming sits around 180-200W, and maximum Furmark load is ~260W.

Nvidia typically go best case scenario so TDP is usually lower than maximum power draw. GTX 580 has a 244W TDP, but power consumption can get as high as 250W during gaming alone. Usually theres no headroom at all.

Nvidia haven't actually specified an actual TDP for the 670Ti though, so the only thing we can draw from this is what it'll never go beyond 300W.

Lol!! Will not get! Nvidia needs to sort out there problem with power hungry chips..... AMD all the way. Full stop!

ITT: people who'd rather Nvidia and AMD skimp on power delivery systems just to make a card's power draw seem smaller on the first glance.

Are custom PCB cards with two or even three 8-pin power connectors somehow worse than reference cards? no. It's just good that the reference PCB has enough headroom for the GPU and for OCing. We have no idea what the TDP or the real power draw of the cards will be...

It does suggest that it's competing with the HD 7970 though.

Why? AFAIK the 7950 also has 1x6 and 1x8.
