Intel to launch HT Mobile P4s on 21 Sept.

And prices to fall a month later, apparently

Intel will bring Hyper Threading technology to its Mobile Pentium 4 processor family during Q4 before replacing the part - at the high end, at least - with mobile versions of Prescott during the first three months of 2004.

So much we've been able to say for some time, thanks to Intel roadmaps we've seen. To that information we can now add the HT-enabled Mobile P4's release date, courtesy of an Xbit Labs report.

The 3.2GHz part will ship on 21 September, and will be accompanied by 3.06, 2.80 and 2.66GHz versions. All will support a 533MHz effective bit rate frontside bus. The four processors will be priced at $653, $433, $294 and $234, respectively, before being cut on 26 October, the same day that Intel has scheduled price cuts to its desktop P4 prices, ahead of Prescott's debut. On 26 October, the new Mobile P4 prices will fall to $433, $294, $234 and $202, the report says.

Don't forget, Pentium M prices are set to fall on 5 October, too, with prices falling by up to 33 per cent.

The 90nm Mobile Prescotts will arrive in Q1 2004, at 3.20, 3.06 and 2.8GHz. It's possible the 3.46GHz version will ship then too, but a Q2 2004 timeframe is more likely. Q3 will see the arrival of a 3.73GHz part. All of these chips will support the 533MHz bus and offer 1MB of L2 cache.

Like the 533MHz FSB Mobile P4s, the Mobile Prescotts will be aimed at desktop replacement notebooks. Their power consumption is going to be high - approximately, 80W, we hear - far in excess of what Pentium M chips consume.

Prescott-based Mobile Celerons are in the pipeline too, coming in at 3.06GHz during Q2 next year. They will have 256KB of L2 cache - double that of today's Northwood-derived Mobile Celerons, but clearly a lot less than the Mobile Prescott's cache complement. They too are likely to be big heat producers, again pitching the parts at desktop replacement roles.

Pentium M-based Mobile Celerons - taken from the current Banias core with only 512KB of cache enabled - are expected to ship next quarter at 1.3GHz, rising to 1.4GHz in Q1 2004. ®
