Intel (INTC - Get Report)  is just about the undisputed leader in many chipmaking lines but a very profitable business unit is seeing some increased pressure. Intel's server CPU business is facing tougher competition than it has seen in years. A big reason for this: The traction AMD (AMD - Get Report)  is seeing for its Epyc server CPU line, which has landed the backing of several top-tier server OEMs and cloud giants. A new server design win with Cisco Systems (CSCO - Get Report)  showcases both Epyc's OEM traction and competitive strengths: Cisco's Epyc-powered servers deliver far more processing power density than its existing Intel-powered server lines, thanks in part to the flexibility of the Epyc platform. Intel still has a lot of competitive strengths of its own in this battle. However, AMD only needs to gain a moderate amount of share for its server revenue to shoot higher. And at current levels, such a revenue surge might not be fully priced into AMD's stock.
