Earlier quoted context omitted.
They put 'crappy' GPU's on die which they continued to upgrade even when the CPU side stagnated. So, while the last upgrade may have been a process issue, the last 4 CPU refreshes have all been classic monopolist behavior. PS: GPU's might seem like something you want on the CPU, but bandwidth is a killer worse they add heat which directly lowers CPU performance.
Frankly the updates to the GPUs have been very minor, over the past few generations. And for some reason, they don't put anything close to Iris or Iris Pro on the desktop CPUs. I've been waiting for a few generations now to get an Intel CPU with decent iGPU but it's really been stagnant. I gave up the wait and pre-ordered a Ryzen last week. I do still think it makes sense for Intel to ship CPUs with those integrated…
Why? iGPU's increase production costs AND reduce both CPU and GPU performance. If Intel wants to produce a separate GPU then more power to them, but that's not what they are doing they are a monopoly extending their dominance to another market at the cost of consumers aka us.
Remember, resistance increases with heat, so even it there where zero manufacturing or performance costs it still increases power consumption.
