I'm recommending a laptop to a colleague, and the specific laptop he has chosen has the above CPU chips as options. Both chips have 2-cores/4-threads. The i7-620M is a 2.66 GHz (4MB Cache) while the i5-540M is a 2.53 GHz (3MB Cache)....both Arrandale architecture.
He is a .NET programmer working with SQL Server and Oracle, and occasionally uses Adobe Fireworks for web-related design elements. He also loves playing around in Adobe Premiere Pro, and does a lot of media/video work.
Would you notice any significant performance difference between the 2? The laptop manufacturer claims that the battery life on both is the same irrespective of the chip used (although I find that hard to believe), but there is a major cost difference between them, with the Core i7-620M being the more expensive.
According to http://ark.intel.com, the one thing that seems different (besides the obvious speeds/frequencies/etc) is a feature called "Embedded" - what is this exactly? You can see the quick comparison here -> http://ark.intel.com/Compare.aspx?ids=43544,43560
I would sincerely appreciate any advice me on this. THANKS!
