This is your processor: Intel® Core™2 Duo Processor T5600 (2M Cache, 1.83 GHz, 667 MHz FSB) Specifications
Using the Intel Processor Feature Filter, selecting # of cores, frequency, and currently manufactured, I see 258 processors:
I did not search for socket compatibility, as they would not be current.
If you use the filter I provided, make sure you reset any features you wish to change.
I cannot help but wonder if there is more to your question.
thanks for your reply Al
what might be a better question is;
What are the major differences between intel i3, i5 and i7 processors?
My Amilo Pi was classed as an all-purpose / mainstream laptop useful for multi-tasking: wordprocessing, photo-editing, viewing movies, gaming (as opposed to a chromebook 'type' which the insurance company want to replace it with). I understand i3 processors are dual-core, like my Amilo, but can they achieve these all-purpose tasks with an i3?
The major differences between the i3, i5, and i7 is cores, threads, and cost. There are other differences as well, like speed, cache, etc.
Here, I selected a current i3, i5, and i7, just for comparison: ARK | Compare Intel® Products
By going to the Intel home page (www.intel.com ), select Products, and then select Processors. Once there, you can view the various processor families. This link gives an overview of Intel processors: 6th Generation Intel® Core™ Processor Family (formerly Skylake)
Regarding your second question, a current processor as we are discussing, will be able to do those tasks, depending on memory and the software you are using, and all are better suited than the T5600 you had, in my opinion. Here, in this link, I have compared your t5600 to a current i3-6100H which would be found in a laptop, as an example of the differences:
And, here is a link to the i3 processors that might answer some of your concerns: 6th Generation Intel® Core™ i3 Processors
Your T5600 is roughly nine years old. There have been improvements, for sure.
Now, all this said, I know absolutely nothing about Chromebooks. So, regarding how they perform with Intel i3 processors, how they are configured with memory and storage, etc, how they will handle your applications, etc, is something I cannot comment on. Here is a recent article that I found comparing Chromebooks to Windows 10 laptops, which may be helpful.
Good luck with the insurance company.
