One thing that is missing from the GeForce GTX 1060 card? SLI bridge connection. There are none and the reason is simple: NVIDIA tells us that SLI is not going to be supported on the GeForce GTX 1060. Rumors have swirled since pictures first leaked that this meant NVIDIA was moving to a PCI Express based data transfer technology for the GTX 1060, similar to what AMD does with CrossFire on its entire lineup. That’s not the case, and would be crazy after the big push for a new SLI Bridge that NVIDIA made with the GTX 1080 launch. The GTX 1060, and we assume any future cards in this class, are not going to support multi-GPU technology.
The decision is kind of astounding to me, really. NVIDIA launched Pascal pushing 2-GPU SLI strongly and eventually ended up cutting out all higher count SLI configurations completely, in order to preserve the consumer experience of 2-Way SLI. Cutting out GTX 1060 owners from SLI because “that market doesn’t really utilize SLI” is just an excuse, not a reason. There is no substantial cost benefit to cutting validation testing for the GTX 1060 if you are continuing to run it for GTX 1080 and GTX 1070. There are plenty of consumers that love the idea of buying a ~$250 graphics card today and adding another down the line, potentially to scale to the performance of one of NVIDIA’s larger, more expensive graphics card. Even worse, you can actually see indentations and spacing on the PCB where SLI connections would have been inserted!
