Intel Core i5-661 Clarkdale Processor Review – Westmere debuts

Synthetic CPU and Memory Tests

Keeping mind that the only other dual-core processor being tested other than the new Core i5-661 is the Core 2 Duo E8500, Clarkdale does pretty well.  The memory bandwidth does appear to take a dramatic hit compared to Lynnfield but that is likely a combination of two fewer cores and the move of the integrated memory controller.  The memory latency results are also indicative of this change as the Core i5-661 has the highest reported results.
