Benchmarks of Intel’s Penryn based dual-core Wolfdale have appeared a couple times in the past month. The early benchmarks tested engineering sample processors and showed Wolfdale, on average, performing 5 percent faster, clock for clock then Conroe. However, benchmarks of the quad-core Yorkfield are virtually non-existent to the public.

Intel’s Yorkfield is not a native quad-core design. As with Kentsfield, Yorkfield features two dual-core dies fused together. The design results in each pair of cores having access to its own pool of shared L2 cache. Since Penryn has more cache, each pair of cores has access to 6MB of L2 for a total of 12MB – up from the 4MB per pair and 8MB total of Kentsfield.
