The values for the CPUs below are determined from thousands of PerformanceTest benchmark results and are updated daily.
- The first section will show basic information for each CPU selected.
- The additional graphs shows the CPU Mark and Single Thread values of each CPU selected.
- An accompany graph, if price data is available, will shows the value for money, in terms of the CPU Mark/Thread Rating per dollar.
- The last section will show approximate yearly running costs for the CPUs.
1Average user usage is typically low and can vary from task to task. An estimate load 25% is nominal. 2Typical power costs vary around the world. Check your last power bill for details. Values of $0.15 to $0.45 per kWh are typical.
