Unannounced Intel Core i7 8086K Spotted
Yes, you read that right, a nostalgic sounding 8086 processor. So then, Intel might be planning a special processor to be released with the 40th anniversary of the 8086 processor?
The processor would/could be in testing stages at Intel, however, in a Chinese forum someone released information and screenshots on it, as Wccftech noted. The Core i7 8086K would be a respin of Coffee Lake S and would get a vase clock of 4.0GHz, however, it would get a boost to 5.1GHz. Everything about Intel's Turbos is vague as they do not release info about it anymore, we I can only assume that 5.1 GHz is a single thread and core boost and 4.4 for the all-core boost.
It, however, would effectively make the proc fast than a Core i7 8700K. The 8086K would be the same six cores part with the same TDP of 95W. This remains to be a rumor though, Intel has not published anything about it. It would not be the first-anniversary processor Intel release, remember the Pentium 20th Anniversary G3258 Processor?
8086K ... right, going to the attic now, gotta find me an MS-DOS floppy disk :-) Oh and keep in mind, although it's a bunch of them (screenshots) they could very likely be fake.

Technically its compatible, but in practice its done using emulation (ie. "Virtual 8086 mode"). The x86 instruction set has evolved quite a bit since those days.
On that note, the basic ARM6 instruction set is also over 25 years old now, with its predecessors going back almost as far as the 8086.
Yes but ARM is versatile in its own architecture (and this is why smartphone love ARM)... Archimede to Raspberry... what a road !!!

Are those cherry picked 8700K CPUs?

Not a failure, as making things compatible is nice too, but at one point the evolution is vital and making things compatible with old thing is like lead ballast...
Other point: the cost of a start from nearly zero.

Virtual 8086 mode is something different. It's for executing real mode applications in protected mode.
Modern CPUs still start in real mode, not in protected mode. That is, they start in non-virtual 8086 mode. It's still supported (and needed, in fact.) It's why you can run DOS. Or why the BIOS still works. Both need an 8086-compatible CPU that is not running in protected mode. It needs to run in 16-bit real mode.
