As all the rest GPU’s in this generation, the GK 106 is made in 28nm manufacturing process and it is based on Kepler architecture. This new chip on a hardware level supports all the latest standards: DirectX 11, Shader Model 5.0, OpenGL 4.2 and technologies directly connected to nVidia’s chips as: PhysX, 3D Vision, PureVideo HD, Cuda etc.
In this edition the GK106 has four working SMX, or 768 stream processors. This is really surprising when considering the class of this card. The same goes for the rest of the specifications of the card, as for an example the 64 texture units, when compared to the Cape Verde (AMD), which in the full edition has only 40.
The number of ROP is directly connected to the memory controller’s and the base speed and when considering that this model will use a 128 bit interface, it’s not hard to presume that there will be 16 of them. The manufacturer has predicted two variations of the card, one with 1GB of GDDR 5 and the other 2BG GDDR5. The additional 1 GB of GDDR according to us is not going to make a difference, that’s why we are comparing three different iterations of this card. The first two work on the same frequencies, but one has double more memory and the third one works on higher frequency, but has 1GB of GDDR 5, so we will see which one has the best price/ performance ratio. And they will be compared with the Cape Verde models made by AMD in the next texts.
On the next few texts we are going to review the cards themselves.
