The obliterating success that the Opteron enjoyed for quite some time left Intel a bit stunned for a while, but now they have struck back, with 2006 showing them gaining in server share. The increases they are seeing are being attributed to the success of the Woodcrest core, one of Intel's dual-core Xeon models.Clovertown made an impact too, though not quite as large due to its introduction late in the year.
It isn't all bad news for AMD, though, as they have gained in the desktop and notebook market, with AMD desktops now rising to over 29% share (for 2006) and notebooks to nearly 20%, a massive increase compared to ten or even five years ago. Still, the success of Core 2 cannot be overlooked, so AMD will have quite the fight ahead of them this year.
