News


Intel discontinues Pentium, Core 2 Duo and Core 2 Quad CPUs
Feb 08, 2011: Last October, we published a story detailing upcoming discontinuation of many Core 2 Duo and Core 2 Quad microprocessors, and two Pentium Dual-core models. Yesterday Intel published Product Discontinuation Notifications (PDN), that provide End-of-Life milestone dates for these CPUs.



Athlon II X2 benchmarks
May 03, 2010: A few weeks ago we acquired a lot of Athlon II processors with C3 core revision. Although we posted pictures and individual benchmarks to Athlon II CPU pages, and added the results to our benchmark database more than a week ago, we decided to provide benchmarks in more readable format, i.e. as a review.
