Lucid, a little-known fabless semiconductor designer, has just announced a new product that could render both NVIDIA’s SLI and ATI’s CrossFire technolgies obsolete. Despite the performance advantages gained using the existing multi-GPU setups, SLI and CrossFire each have drawbacks that prevent many enthusiasts from adopting either. Logic would lead most people to believe that using two video cards together would result in twice the performance. After all, last we checked 1+1=2. However, neither SLI nor CrossFire, despite recent strides, do not scale linearly. In fact, after a full two years of maturing, all NVIDIA and ATI have managed is a performance increase of 40-70% when adding a second card.
