NVIDIA’s RTX cards are a gamble on the future of gaming

NVIDIA's RTX series of GPUs has been a long time coming. The company's last meaningful hardware revision, the 10 series, came out back in May 2016. And real-time ray-tracing, the intensive rendering technique that RTX cards purportedly make a reality, has been dreamed about for decades. But, although it hasn't dominated the headlines as much, the most important change RTX brings is the shift away from raw power and towards algorithms and AI.

Next week, two cards, the $700 RTX 2080 and $1,000 RTX 2080 Ti, will be vying for your cash, followed in October by the RTX 2070, which at $500 is likely to be the best seller of the three.
