AMD has lost another high-ranking staffer, this time bidding farewell to Corporate Fellow and Heterogeneous Systems Architecture (HSA) expert Phil Rogers.
The financially-troubled AMD has been suffering something of a brain-drain of late, culminating in CPU design giant Jim Keller leaving the company for the second time
in September - even before Zen, the new microarchitecture on which he had been working, hits shop shelves. Now, HARDOCP
was the first to report that Corporate Fellow Phil Rogers has left the company as well - and, worse still, he's heading over to GPU rival Nvidia to act as its chief software architect.
Rogers was appointed an AMD Corporate Fellow back in 2007, where he was given a key role in the development of the company's 'Fusion' architecture. Designed to blur the lines between CPU and GPU processing and strengthen the performance of the company's accelerated processing unit (APU) range, Fusion would morph into the Heterogeneous Systems Architecture (HSA), a theoretically vendor-neutral standard which aims to demonstrate how CPUs and GPUs should work cooperatively.
HSA forms a central pillar of AMD's vision for the future of computing, especially given its powerful GPUs and relatively weak CPUs - with the latter promised to change upon the release of the much-vaunted Zen microarchitecture. Now, though, the company will have to do without Rogers' input - while Nvidia has hinted that his HSA know-how could find its way into future server-oriented products powered by GeForce GPUs and Tegra CPUs.
AMD has not commented on the departure.
