Intel's Penryn core finally hits mass production under the codenames Yorkfield (quad core) and Wolfsdale (dual core), beating AMD to the punch with the release of the first lead-free CPU and bringing a massive 6 or 12MB L2 cache to the table. Built using Intel's P1266 process with Hafnium-based transistors in a 45 nm design, the new cores are geared towards exceptional energy efficiency with the added bonus of Nehalem New Instructions (NNI) also known as SSE4 instruction set.
We'll be reviewing the feature set of the new CPU, and look at performance, overclocking and energy efficiency of Yorkfield compared to the older versions of Intel processors and .. of course, the competition from Austin.
