Yes, that is correct. The Intel Core i3, i5, and i7 series of processors all have a minimum of 2 cores and a maximum of 8 cores. However, the i3 series does not support Hyper-threading, while the i5 and i7 series do. Hyper-threading is a technology that allows each physical core to act as two logical cores, effectively doubling the number of cores available to the operating system. This can improve performance in applications that are able to take advantage of multiple cores.
Here is a table of the minimum, maximum, and supported core counts for each Intel Core series:
| Series | Minimum cores | Maximum cores | Supported Hyper-threading |
|---|
| Intel Core i3 | 2 | 5 | No |
| Intel Core i5 | 2 | 6 | Yes |
| Intel Core i7 | 2 | 8 | Yes |
It is important to note that the actual number of cores that are available to the operating system may vary depending on the specific processor model and the operating system that is being used. For example, a 6-core Intel Core i5 processor may only have 4 cores available to the operating system if it is running Windows 7.
