FUD Zilla heard whispers that the performance of AMD's Bulldozer processors will come really close to Intel's six-core Core i7 chips:
However, initial test scores that slipped to a hands of industry source are suggesting that Bulldozer should come really close to new Core i7 six-core CPUs. Bulldozer has both six and eight cores in the pipeline and they should be launching before the end of Q2 2011, at least that is the current schedule.
The performance of Bulldozer should come really close to Core i7, but we don't know if this might be enough to take Intel's high end market dominance. Samples of Bulldozer are out for a while now and the full production should start as soon as this quarter.
