Intel already has Penryn and it even showcased it to selected press in its V8 gaming machine. What many don't know is that you can't overclock the current Penryn by more than 10 per cent.
The 3 GHz core will run at up to an additional 300 MHz and that's about it. Intel is expecting the next revision of the Penryn core within the next few weeks and this one is supposed to reach the sky, as its 45 nanometre and has significantly lower heat dissipation than Kentsfield.
Intel is doing fine since it doesn’t plan to launch any desktop variants of the 45 nanometre Penryn until Q4. This core is certainly in better shape than AMD's Barcelona.
