I wouldn't buy into the "we have abandoned the gaming market" nonsense. If AMD can make a profit, even a small one, then they will be there.
Chasing the HPC market is what they need to do in order to rebuilt their R&D budgets. Lisa Su likes to compete. More importantly, she likes to win. Given the shakeups she has overseen, coupled with the wonderful success Ryzen has been, all points toward AMD coming out swinging. It might take 18-24 months but I believe it will happen.
I'm actually putting my money where my mouth is abd picking up more AMD stock. It has no where to go but up. Way up.
It was reasonably easy for AMD with RyZen to catch Intel. They have almost been stagnant since Sandy Bridge launched. The same cannot be said for Nvidia. RTG certainly has a battle on its hands there. Still, now that Raja has gone I'm really interested In the direction they take.
