On Sunday, Intel instituted broad price cuts on processors, spanning the Core 2 Quad, Core 2 Duo, Pentium dual-core, Celeron, and Xeon product lines.
Some of the cuts are in response to Advanced Micro Devices' recently-introduceddesktop platform. AMD's Phenom II X4 940 (3.0GHz), for instance, is priced at $275.
Intel cuts were concentrated on quad-core chips like the Q9650 (3.00GHz), reduced 40 percent, to $316 from $530, to counter AMD's Phenom II. But Celeron processors received some of the largest reductions. The mobile Celeron 570 (2.00GHz), was slashed 48 percent, to $70 from $134, for example.
Some Xeon processors also received hefty cuts. The price on the X3370 (3.00GHz), for instance, was cut 40 percent to $316 from $530.
The Pentium dual-core E5200 was reduced 24 percent to $64 from $84.
The mobile Core 2 Duo P8600 was shaved 13 percent, to $209 from $241. The P series of mobile Core 2 Duo processors have a thermal envelope (Thermal Design Power or TDP) of 25 watts versus 35 watts for mainstream mobile chips.
Intel also introduced new processor models such as the desktop Core 2 Duo E7500 (2.93GHz), priced at $133 and the Core 2 Quad Q9550s (2.83GHz), which is a low-power variant--with a thermal envelope of 65 watts--of the 95-watt Q9550.
