Some more details of Core 2 Duo P8700
The Core 2 Duo P8700 belongs to the Penryn Architecture and has a decent CPU performance with a relatively high 2.53 GHz Clock frequency. It has some decent features including ability to reduce the clock frequency to save power. The processor does not feature integrated graphics or an integrated memory controller as in the newer Arrandale or the Sandy Bridge processor.
Some more details of Core i5-540M
The core i5-540M is a Mid level moderate performance notebook processor with impressive performance as evident by its benchmark results.
The integrated GPU provides entry level graphics performance. The GPU supports independent turbo boost with maximum turbo frequency of 766 MHz with a base frequency of 500 MHz.The Core i5-540M does support the AES instructions and Intel Trusted Instructions (in addition to V-td). The the core i5-5xxM processors have higher turbo frequency compared to the corresponding core i5-4xxM parts, giving it an edge.
