Mini-ITX Sized Package with a Full Sized GPU
PC components seem to be getting smaller. Micro-ATX used to not be very popular for the mainstream enthusiast, but that has changed as of late. Mini-ITX is now the hot form factor these days with plenty of integrated features on motherboards and interesting case designs to house them in. Enthusiast graphics cards tend to be big, and that is a problem for some of these small cases. Manufacturers are responding to this by squeezing every ounce of cooling performance into smaller cards that more adequately fit in these small chassis.
MSI is currently offering their midrange cards in these mini-ITX liveries. The card we have today is the GTX 760 Mini-ITX Gaming. The GTX 760 is a fairly popular card due to it being fairly quick, but not too expensive. It is still based on the GK104, though fairly heavily cut down from a fully functional die. The GTX 760 features 1152 CUDA Cores divided into 6 SMXs. A fully functional GK104 is 1536 CUDA Cores and 8 SMXs. The stock clock on the GTX 760 is 980 MHz with a boost up to 1033 MHz.
The pricing for the GTX 760 cards is actually fairly high as compared to similarly performing products from AMD. NVIDIA feels that they offer a very solid product at that price and do not need to compete directly with AMD on a performance per dollar basis. Considering that NVIDIA has stayed very steady in terms of marketshare, they probably have a valid point. Overall the GTX 760 performs in the same general area as a R9 270X and R9 280, but again the AMD parts have a significant advantage in terms of price.
The challenges for making a high performing, small form factor card are focused on power delivery and thermal dissipation. Can the smaller PCB still have enough space for all of the VRMs required with such a design? Can the manufacturer develop a cooling solution that will keep the GPU in the designed thermal envelope? MSI has taken a shot at these issues with their GTX 760 Mini-ITX OC edition card.
