If Excavator is some sort of miracle that crushes Intel and wins back tons of marketshare for AMD on mobile, desktop, and workstation markets then it would be reasonable to keep making big chips. But so far Bulldozer family has been a failure and each iteration only offered marginal improvement. Even Steamroller, which had higher IPC, only had marginally higher performance because of lower clocks. Judging from the trend since C2D AMD has barely been competing against Intel on the big chip front.
And worst of all, Baytrail is proving to have equal or better CPU performance than Jaguar at a lower TDP, and clearly it's much more popular with OEMs. And Intel wants to put their Atom architectures on the Tick-Tock cadence. Pretty soon AMD won't be competing on the ultra mobile front either. All they'll have is GPUs (in which they lost marketshare over the past quarters), ARM servers, and consoles.
