The Reference PCB design along with the first performance results of NVIDIA's upcoming GeForce GTX 670 graphics card have been exposed. The Geforce GTX 670 would be the third GPU to feature the 28nm Kepler GK104 core and as we noted previously, would be based on a much smaller PCB.
As you can see, The Kepler Gk104 is accompanied by a 4 Phase VRM which is powered by dual 6 pin connectors. There are four memory chips at the front and four at the back of the PCB which suggest a 2GB (256-bit) wide memory however an additional room for eight more chips mean we would be looking at 4GB non reference models soon.
The Kepler GK104 has one of its SMX units disabled totaling at 1344 Cuda Cores, 112 TMUs and 32 ROPs. Display outputs include two DVI and a single HDMI + Display port. Two SLI connectors allow for 4-Way multi GPU configuration.
The card was from manufacturer Gigabyte as suggested from the codename "GV-N670OC-2GD2" was pitted against the Radeon HD 7950 and GeForce GTX 570. The results obtained were quite shocking:
