Earlier this month Intel rolled out their new Clarkdale processors that are built on a 32nm process and making them rather unique is that integrated on the dual-core Westmere-based part is an integrated graphics processor. The Clarkdale CPUs launched under the Core i3 and Core i5 brands (along with a Pentium version) and since their launch have received favorable reviews, well, under Windows. We have now received our Core i3 processor and have carried out various processor benchmarks under Linux to see how well Clarkdale runs with the penguins.
The 530 and 540 are the first two Clarkdale processors that launched the Core i3 series after the Core i5 and Core i7 brands were introduced last year. To distinguish the Clarkdale Core i5 processors from the Lynnfield Core i5 processors launched last year, the new Clarkdale CPUs all have models within the Core i5 6xx series (currently the 650, 660, 661, and 670 models). Arrandale is the codename for Intel's mobile version of the Clarkdale processor and they too are distributed amongst the different Core brands. The Clarkdales in the Core i3 and Core i5 series have many similarities like boasting a 733MHz GPU clock, LGA-1156 Socket, utilize DMI (Direct Media Interface) rather than FSB, and support other common Intel CPU features like Enhanced Intel SpeedStep Technology, and Intel VT-d for virtualization. Clarkdale CPUs also support the SSE 4.1 and SSE 4.2 extension sets. Differing the Clarkdales though is that the Core i3 models lack support for Intel Turbo Boost.
In regards to the Intel Core i3 530 Clarkdale that we have for testing in this article, it operates with a stock frequency of 2.93GHz, is a dual-core 32nm part, has 4MB of L3 cache, supports Hyper Threading, and has a 73 Watt Thermal Design Power. The Clarkdale GPU is built on a 45nm process, unlike the rest of the CPU that is shrinked down to 32nm. We bought this Intel Core i3 processor for $120 USD, which is the cheapest Clarkdale besides the Intel Pentium G6950 that is just short of $100. Intel backs the Core i3 with a three-year limited warranty.
