This page aims to show the statistics obtained from the CPU-Z online database. As a reminder, CPU-Z is a popular freeware that gathers PC systems hardware information : CPU, memory, chipset ... After the scan, the users can generate a submission file and create a new record in the database, that is named a validation. Those anonymous validations can be then used as an overclocking proof, or even as a description of a PC farm for companies.

Created in 2005, the CPU-Z database contains around 300,000 entries today and gets 3,000 new entries per week, most provided by persons who do not overclock or tweak their system. As a result, the database is a relevant representation of the general PC market. We found it then relevant to process the database in order to generate a set of statistics. The statistics are presented as two tables :

• a "snapshot" view, updated every day and based on the data gathered during the three last months ;
• the evolution on the 12 last months, updated and commented every month ;

• Duel : Intel Vs AMD

The success of the AMD Athlon 64, in comparison to the Intel Pentium 4, resulted in an increase of the AMD market share in 2005 and 2006. Since that time, the release of the Core 2 Duo by Intel changed that distribution and reduced the part of AMD. Today, Intel leads with 67% of the general market, in comparison to 50% two years ago. AMD lost 6% in one year, and only a more competitive Phenom could change that.

• Evolution du nombre de coeurs 

As we can clearly see on this graphic, the number of dual core CPUs overtakes the number of single core CPUs from may 2007. Since that moment, the part of single core CPUs is constantly decreasing, and is now one-third of the total. In the same time, the part of dual core CPUs increased, to finally top at 55%, because of quad core CPUs. As a manner of fact, Intel Core 2 Quad became popular from august 2007, due to the price drop at the beginning of summer. Now, quad core CPUs are 11.4% of the total, and that part is increasing.

• Côté AMD : évolution des modèles 

The transition from the AMD Athlon 64 line to the Athlon 64 X2 line occured in may 2007 as well. Since that time, the new X2 represent 70% of the sales of AMD processors. On the contrary of what happened for Intel CPUs, the AMD quad core CPUs line (Phenom) is still stuck at 1% of the sales, most likely due to the problems that the new CPU line encountered. As a final note, the old Athlon XP still represents 10% of the market, that can be explained by the fantastic popularity of that CPU until 2005.

• Côté Intel : évolution des modèles 

Speaking about Intel, the poor performance provided by the latest Pentium 4 greatly accelerated the transition to the Core 2 microarchitecture. At the beginning of 2007, the Core 2 Duo already represented 45% of the market, with a peak during the summer. Since that time, this number is slowly decreasing as the repartition of Core 2 Quad increases. The sales of the Intel quad core reach 20% at the end of 2007. The entry-level Celeron is less and less popular, that can be easily explained by very inexpensive Core 2 Duo models and Pentium E2xxx. Finally, the Pentium D only represents 5% of the total, and is about to completely disappear.
