To test different types of Clarkdale processors we took a sample for each type of this dual-core CPU:
- Core i5-661 with the nominal clock speed of 3.33 GHz, Hyper-Threading and Turbo Boost support, which increase the clock frequency of this processor to 3.46 GHz or 3.6 GHz under different types of workload.
- Core i3-540 with the nominal frequency of 3.06 GHz and Hyper-Threading support. This CPU doesn’t support Turbo Boost.
- Pentium G6950 with the nominal frequency of 2.8 GHz. This processor belongs to the low-end segment that is why it not only has no Hyper-Threading and Turbo Boost support, but also features smaller 3 MB L3 cache.
We are going to compare these three new processors against several current typical solutions with two, three and four cores for LGA1156, LGA775 and Socket AM3 systems that belong to the mainstream segment and from the price point prospective can compete against Core i5, Core i3 and Pentium G series CPUs.
The list below shows all the hardware components that were used during our test session:

As you can notice from the list of used testbed components, we didn’t use any mainboards that would allow us to use the graphics adapter integrated into new Clarkdale processors. Today we are going to leave out the discussion of its performance. But very soon we will offer you an in-depth article devoted to performance comparison between the Clarkdale integrated graphics core and integrated chipsets for LGA775 and Socket AM3 platforms.
* - We would like to thank AMD Russia for providing us with ATI Radeon HD 5870 graphics card for this testbed.
