And the best chip stock of the future is...

Shares of NVIDIA surged to a four-year high as demand for its graphics chips increases on the trend toward 3-D devices and displays. Meanwhile, rival in the chip space Micron Technology, a maker of memory chips for data centers and all kinds of devices rode the 'Internet of everything" trend to big gains in 2014, but is down this year. These two technology companies are squaring off tonight against each other on "Fast Money," as part of the show's Madness challenge. Here's a preview of their thoughts so you can make the trade now. NVIDIA 's stock is up 14 percent in 2015, while Micron Tech's shares are down 20 percent. One reason for that difference is because NVIDIA keeps expanding into new markets, while Micron is focusing mainly on memory chips, according to some of the Fast Money traders. "NVIDIA is now positioning (itself) as a key automotive technology provider" said Pete Najarian . "That's potentially a massive market for processing information to instruct autonomous cars." NVIDIA's management said automotive could add $5 billion to revenues. Steve Grasso agrees with Pete on NVIDIA's bold expansion plans, citing its move to make not just chips for video games, but also make a video game console itself. "I expect further money coming into the stock that is now seen as the disruptor in the gaming world, taking on Microsoft and Sony," said Grasso, referring to Nvidia's recently released video game console for TVs called "Shield." But not everyone is as bullish on the stock. Goldman Sachs downgraded ticker 'NVDA' to sell from neutral on Monday, slashing the company's target price to $20, or 13 percent lower from where the stock trades. In fact, lofty valuations are cited as a concern among investors. NVIDIA shares trade at 19 times forward earnings, or an 8 percent premium to its five-year average. That compares to just 7 times for ticker 'MU,' or a 67 percent discount. So the battle looks to be a classic growth vs. value match-up. UPDATE: Fast Money traders came out in favor of NVIDIA. The company moves to the next round. "NVDA has more runway than MU to expand," said Brian Kelly . "The new use cases for the GPU chip beyond graphics provide multiple catalysts for NVDA." How it works: For this year's Fast Money Madness Challenge, 16 technology companies square off against each other. Eight of the leading stocks in the S & P information technology index will go up against eight of the laggards. For the next three weeks on "Fast Money" (5 p.m. ET), the four panelists will vigorously debate the stock matchups in our bracket.
