Upcoming "Penryn"-based 45nm high-end quad-core CPUs may well attract an even higher price premium than before, it has emerged. Intel has apparently informed customers that next year"s Core 2 Extreme processors will cost up to 50 per cent more than today"s models. According to newly released Penryn pricing data posted by a number of websites, November"s Core 2 Extreme QX9650 will cost $999 when sold in batches of 1000 chips. That"s the price point Intel has maintained for the Extreme line of gaming processors since the family was introduced back in the Pentium D days.
