Clarkdale K-0 stepping coming in July

Intel will update the Clarkdale architecture with a new stepping by Summer. The current C-2 stepping of Clarkdale was released in January and will be replaced by the new K-0 stepping in July. Intel Core i3-530, i3-540, i5-650, i5-660, i5-661 and i5-670 are the first models to be updated with the new core. You can find the K-0 stepping today already, with Intel’s new Core i5-680 CPU.

In August the entry model, Pentium G6950 is expected to be released with K-0 stepping, but whether Intel has made any substantial breakthroughs with the 32nm process is uncertain. The only thing required for K-0 support is a BIOS update.

As usual Intel will be selling steppings side by side as the old are being phased out. If you’re picky about your processors we have a list of the product names and codes to look for.
