Here you can find information about obsolete and rather current processors and co-processors.
I tried hard to gather useful information about all items and topics in this collection. However, there will be incomplete, missing or wrong data in several places. You can participate in enhancing and extending this site by adding your comments and knowledge. Just click on the 'add comment/info' links on places like CPU information pages, class overviews and company profiles to enter your messages.
All CPU pictures on the site were taken by me and show actual items in the collection. They all have the same resolution to make it easier to compare the different processors' sizes (except some slot cartridge processors like the Pentium II, which are reduced by 50% in detail views because they are very large). If loading speed should be low try the 'Configure' link to adjust appearance of images and visual styles.
