This post has been repeatedly edited! Some important information has been changed in this post.
For some time Intel have been including hardware in their CPUs that restricts the freedom of software. This isn't good. It is commonly known as Digital Rights Management, but is better known as Digital Restrictions Management.
I spent a bit of time investigating the 'Advanced Technologies' on Intel chips and two in particular to avoid are Intel TXT (Trusted Execution Technology) and Intel Insider (just check out the responses to the Intel article!)
If you have to get an Intel CPU, and would like to get the most modern one without either TXT or Intel Insider, then choose the following:
The information I have enclosed in quotations was double checked today before I posted it. Somebody has kindly written to me and checked themselves and found that both these CPUs have Intel Insider! I apologise for providing very misleading information.
The most recent information regarding these two CPUs taken from the Intel website is here:
I don't know how this mistake came about, as I did check it. I can only assume that Intel updated their website today, perhaps as a result of my enquiries with their technical support staff this afternoon. I hope nobody has bought one of these Intel Insider chips as a result of my post. I used both Wikipedia and the Intel website to find my information.
End of second edit
I apologise for all these edits. I have been checking the Intel website for information and the information seems to have changed again. Perhaps I should delete this post altogether, but some of you have read it and may need to see the latest information.
If for some reason these chips just aren't fast enough, and you have to get an Intel, then the most modern CPU without TXT but (unfortunately) with Intel Insider is below:
Mobile Processor: Intel® Core™ i7-2670QM Processor(6M Cache, up to 3.10 GHz)
Desktop Processor: Intel® Core™ i7-3930K Processor (12M Cache, up to 3.80 GHz)
Edited to add:
Be careful! The Intel® Core™ i5-3210M Processor (3M Cache, up to 3.10 GHz, rPGA has Intel Insider! They both have Intel Insider!
The i7-3930k is not the most modern, but is the most reasonably priced, at about $580. For the very most modern Desktop CPU from Intel with no TXT but unfortunately with Intel Insider, then chose the following, at $1000:
Desktop Processor: Intel® Core™ i7-3960X Processor Extreme Edition (15M Cache, up to 3.90 GHz)
Write to Intel. Tell them that you are not happy with their DRM. It won't take a moment. Get your friends to write too!
By the way, if you would like to check whether your hardware supports free software, visit h-node. All hardware listed there works without the need for any proprietary drivers, so you will be sure it works with your system.
Your freedom is important!
