Shares of Nvidia (NVDA - Get Report) are climbing Wednesday, up more than 13% after the company beat on earnings per share and revenue expectations.

Sales grew by nearly 50% and Nvidia topped analysts' EPS estimates by more than 25%. This was one of the best quarters we've seen, TheStreet's Jim Cramer, manager of the Action Alerts PLUS portfolio, said on CNBC's "Mad Dash" segment. 

Of course, Nvidia is getting credit for being in hot growth markets like autonomous driving and the cloud. It's got customers like Amazon (AMZN - Get Report) , Alphabet (GOOGL - Get Report) , Microsoft (MSFT - Get Report) , Lockheed Martin (LMT - Get Report) and even the U.S. Navy. 

But one business segment that doesn't seem to get the credit it deserves? Gaming.

Multiplayer online battle arenas -- MOBA for short -- is driving a surge in chip demand. An increase in gaming not only benefits companies like Electronic Arts (EA - Get Report) and Activision Blizzard (ATVI - Get Report) , but also the chipmakers like Nvidia. 

More people are gaming than those watching Netflix (NFLX - Get Report) , HBO, Hulu and ESPN combined, Cramer reasoned. It's just one reason why Nvidia is doing so well right now, he concluded. 

"Our Datacenter GPU computing business nearly tripled from last year, as more of the world's computer scientists engage deep learning. One industry after another is awakening to the power of GPU deep learning and AI, the most important technology force of our time," said CEO Jensen Huang.
