Earlier this month a rumor hit the web that AMD's Kaveri processor may be delayed to 2014, coupled with speculation that the project may even get cancelled. ExtremeTech spoke to AMD and received word that "Kaveri with Steamroller core is still a product in development at AMD". Additionally, AMD spokesperson Phil Hughes also shared that AMD will continue to develop big cores.
That said, Hughes comment only referred to Steamroller. It’s possible that AMD has killed Excavator in favor of an entirely different design. It could be planning to scale Jaguar’s (second-generation Brazos) CPU core upwards to fill a gap in the lower end of the desktop market that Trinity currently addresses. We’ve heard rumors that the company might try to build a new CPU architecture to address Bulldozer’s faults rather than trying to refine the current core into something that competes with Intel’s current high-end chips.
