The real real problem is that we don't know how to effectively use growing transistor budgets to speed applications up compared to the single core era. Adding cache and more cores are both options that make for very sublinear improvements at the margin. (for 95% of usage - somen niche things can utilize resources better, those not coincidentally often being the focus of benchmarks)
