Intel formally announced its first 45nm desktop processors a couple of weeks ago, and today we've noticed that the chips are starting to peek their heads out into the retail world. Newegg, for one, has begun selling the Core 2 Duo E8400, although that seems to be the only 45nm Penryn-based desktop processor the e-tailer currently has listed.
The chip is available for $224.9 with free shipping—considerably cheaper than the equivalent 65nm model, the Core 2 Duo E6850, which Newegg sells for $279.99 with free shipping. Both processors are clocked at 3GHz with 1333MHz front-side buses, but the E8400 has 6MB of shared L2 cache instead of 4MB like the E6850. The E8400 should also benefit from the power consumption and architectural enhancements of the Penryn core, yielding lower power use and higher clock-for-clock performance.
