NVIDIA's RTX speed claims fall short without game support

At its big RTX event at Gamescom, NVIDIA made some bold claims about its new Turing RTX cards. First and foremost was that the GeForce RTX 2080 offered performance "six times faster" than current 1000-series Pascal-based GTX cards. That's in large part because of new ray-tracing tech that helps the GPUs calculate complex game lighting much more quickly. "This is a new computing model, so there's a new way to think about performance," said CEO Jensen Huang. The new GeForce RTX 2080 Ti, 2080 and 2070 cards are quicker than ever, but the increase is not nearly as dramatic as the "six times" claim.
