The Intel Pentium D processor provides a bottom of the range option for those looking for a dual core processor without the cost involved in getting many of them.
This chip is fairly new to the market and mates two Smithfield cores together, with an FSB of 533MHz, one L2 cache of 1MB each for the cores. Unlike its brothers and sisters in the 800 series of dual-core processors from Intel, which all run at 800MHz, this one runs slower at 533MHz, with a multiplier of 20 to get to a speed of 2.67GHz.
In the review at legitreviews.com, they managed to push the FSB up to 760MHz without any problems from the processor and loaded up Windows and ran their tests without any problems. The actual increase in performance did not quite match the rise in processor speeds, with the overall change being about a 29% in performance or so.
The processor goes past the levels of the 840 processor and starts to come near the level set by the 840 Extreme Edition.
There is a lot of praise for this chip on the site and the test scores go to show how much it can perform, and how much you can get for your money from the lowest priced dual-core processor around. With a decent motherboard for under a hundred bucks, you will be able to get a processor that is capable of running up to 3.8GHz with a little bit of overclocking.
