'Yonah' Celeron M 420, 430 ship in Japan

Intel's as-yet-unannounced Celeron M 4xx series - the first budget-priced processors derived from the chip maker's 'Yonah' core - have gone on sale in Japan, according to local news sources.

As Reg Hardware exclusively revealed in January, Intel is preparing a trio of single-core Yonah-based Celeron Ms: the 410, 420 and 430, clocked at 1.46, 1.60 and 1.73GHz, respectively. All three are fabbed at 65nm, contain 1MB of L2 cache and support a 533MHz frontside bus clock frequency.

According to a Japanese-language Akiba PC Hotline report, boxed versions of the 420 and 430 this week went on sale in Tokyo priced at ¥14,780 ($125/£72) and ¥17,780 ($150/£86), respectively.

The 410 isn't expected to ship until Q3. The following quarter should see the debut of the 1.86GHz 440.

Intel is also known to be preparing a 65nm Low-Voltage Celeron M, the 423, set to be clocked at 1.06GHz. A faster model, the 443, is due for release in Q1 2007. ®
