NVIDIA Kepler GK104 To Use 6 + 8 pin Connectors, Possible 300W TDP
The NVIDIA Kepler GK104, which is expected to debut as the “Geforce GTX 670 Ti”, will be using 6 pin + 8 pin power connectors. The new graphics card could potentially draw up to 300 watts of power, using 75W 6pin + 75w PCIe bus + 150w 8 pin equaling a 300W maximum. NVIDIA’s design calls for two phases, NVVDD-PH1 and PH3 which will power memory and the board as well as third party chips, while three phases: NVVDD-PH2, PH4 and PH5 will power the GPU. Apparently the board studied by VR-Zone was manufactured in the third quarter of 2011 by Foxconn, this just re-affirms that Kepler has been ready but yields were just to low for launch. Let’s hope NVIDIA will unveil their Geforce Kepler GPUs soon, as I am excited to see what kind of performance they will bring.
The board in question was manufactured in the third quarter of 2011, meaning that NVIDIA has had Kepler for quite some time. Given that the original plan called for Kepler debut in 2011 and Maxwell in 2013, it’s obvious that the yields were too low to initiate launch production. In the recent financial analyst call, Jen-Hsun commented that the 28nm supply will be “constrained through the year (2012)”.
