Until recently, McNamara served as the president and GM of Intel's Network and Custom Logic Group.
With its most recent Zen-based server offerings, AMD has the upper hand over Intel but winning marketshare is a slow process as things aren't as easy in the server market as in the consumer market. At the moment, AMD is gaining marketshare, but Intel is also selling a lot more Xeon processor than before. Part of this is a side effect of the CPU vulnerabilities that have been found in Intel CPUs over the past two years.
Each new security patch lowers performance and this forces business owners to buy more Xeon processors if they want to maintain the same level of performance that they previously had. So far, buying more Xeon processors has been the easy route versus testing and validating AMD's EPYC CPUs.
