Nvidia later reintroduced SLI in a different manner in 2004. This enabled impressive scaling of graphics power, leading to better benchmark and in-game performance.

Introduced with its Voodoo2 line of graphics cards in 1998, it allowed two or more GPUs to work side by side on the same graphical problems. SLI, or Scalable Link Interface technology, was originally created as the scan-line interleave technology by 3dfx, well before it was bought out by Nvidia. Which is better: SLI, or ? While the 1070s will be faster in some games, for almost everything else, you should pick the RTX 2070. This is simply because most games offer better support for faster single cards, than they do for a pair of slower cards. If you want reliable, high-speed gaming, an RTX 2070 is going to offer you better performance than a pair of GTX 1070s in SLI. SLI and indeed Crossfire, are practically dead technologies at this point. Throw a pair of GTX 1070s at 3DMark Time Spy, and they will easily outstrip an RTX 2070. So, surely that applies today too, right? Would a pair of GTX 1070s in SLI be as fast or even faster than a newer RTX 2070? In benchmarks, absolutely. It was a good way to save money by throwing a second hand card in when a new generation debuted, meaning you could get most of the performance of new-gen cards, with old-gen hardware. Not too long ago, if you wanted to drastically increase your PC’s graphics power, a great way to do so was to add a second graphics card, sharing the load between them using AMD’s Crossfire or Nvidia’s SLI technologies.
