Question – Help identifying this cpu

I found this in some stuff I purchased.The searches that i’ve done gives me mixed information for I7 to i9 it’s obviously not made for human consumption l o.L never made for public sale as it’s a beta part. Any information that you can help me out with would be great like. Is it usable? Is it worth messing with and what the heck it really is?
I was in the computer business back when 8088 was the talking dog. I got out in the mid-eighties, but I still have always built my own pC’s, but I am far behind most all of you folks.
