I'm trying to get Sling TV set up on an older iMac. It has

  • 10.6 (the minimum required OS),
  • 2.5 GB RAM (~2.5 times the required memory), and
  • a 2 GHz Intel Core 2 Duo.

However, the Sling TV web site claims you need a "2 GHz Intel Core Duo". I wasn't aware that there was such a thing, but Googling for the difference between them turned up nothing apparently useful, and even Googling for "2 GHz Intel Core Duo" turned up very little—most results refer to the 2 GHz Intel Core 2 Duo. HOWEVER there is a page from Intel which mentions "2 GHz Intel Core Duo". Is this a different CPU, or just another way of referring to the 2 GHz Intel Core 2 Duo?

If they are different CPUs, can I assume the Core 2 came later, and therefore I have a newer CPU than Sling requires?

They are different processors.

The Core Duo was released earlier in 2006. The Core 2 Duo was released mid 2006.

For specific dates, and more info on the processors, this Wiki page is a good reference: https://en.wikipedia.org/wiki/Intel_Core#Core_Duo


Yes, the Core 2 Duo and Core Duo are different and the Core 2 Duo came later so your iMac should support any software that requires at least a Core Duo.

You can tell because the Early 2006 MacBook Pro used the Core Duo while every MacBook Pro after that until 2010 used a Core 2 Duo. This isn't definitive in proving that the Core 2 came after the Core, but Apple's not going to continually downgrade the processor in its top-of-the-line laptop year after year, plus the "2" usually denotes a successor anyway.
