Meet Intel’s Clarkdale, the World’s First 32nm CPU
Clarkdale will be a 2 core, Nehalem microarchitecture CPU - the first to be made on a 32nm process. Like the rest of the Nehalem family, Clarkdale uses Hyper Threading, which allows each core to handle two threads. The cache design also appears to be the same, at least on a per core basis, giving the Clarkdale 4MB of shared L3 cache.
It also has an integrated, DDR 3, memory controller as does the rest of the Core iX branded chips. The Core i7 has a triple channel controller, though, while Clarkdale (and Lynnfield) are dual channel. It also brings the graphics controller onto the CPU (like Core i5, but not Core i7). Even the integrated graphics are brought onto the processor in the Clarkdale, about which Intel is pretty excited, though the silver cloud definitely has a grey lining. More on Intel’s graphics on the CPU later.
Further differentiating it from other Nehalems, Clarkdale will use its own socket, LGA 1155. We knew before Core i7 launched that later, and lesser, Nehalems would use a different socket than the X58’s LGA 1336. Now, we have learned that upcoming 2 and 4 core Nehalems will require different sockets: LGA 1156 for Lynnfield; LGA 1155 for Clarkdale.
