If you think winning by 20-25% at twice the price is destroying the competition, you, sir, (to use an aphorism) need to stop drinking the Kool-Aid. Yes, they finally have the lead, but with ten times the resources of AMD, they could've done it before, couldn't they?
There's also the elephant in the room - DirectX 12. AMD is touting their asynchronous compute engines as being able to significantly accelerate workloads. We don't actually know what Broadwell brings to the table here, let alone how both perform.
I applaud Intel for rolling Iris Pro out in a far wider fashion, but we're also only seeing low to medium quality benchmarks, and mostly at 720p. That hardly tells the true story. For all we know, Intel is probably even more ahead when you crank up the details, then again the eDRAM could start to be choked. I think more tests are required before shouting from the rooftops about one product destroying another.
