Today is the official launch day for Intel's Core i7 920 processor with the new D0 stepping revision. Similarly to the arrival of the Core 2 Quad Q6600 G0 stepping in summer 2007, this CPU will initially be difficult to find as it shares the same model number of its C0 predecessor.

TankGuys.com, a popular enthusiast hardware distributor, has recently listed the retail edition Core i7 920 D0 stepping CPU on its site with pre-order spots going for $5 and final pricing going for $319.99. The chips are expected to ship out on March 25th, yet interestingly enough the site claims them to already be in stock.

Contrary to the delightful price drop we've seen on C0 stepping chips, this revision will retail for an average starting price of $284 in quantities of 1000. Yet, the $320 price point that TankGuys has listed seems most sensible for popular e-tailers and distributors.

On another note, Intel has issued a specification update sheet including errata information dated January, 2009 which can be found here. Rest assured, there is nothing listed in the sheet that has not already been fixed with BIOS updates.
