Are there x64 Cpus without Sse/Sse2?

[CHips]

It looks like all Socket 754 and 775 x64 processor have Sse/Sse2, the Socket 478 SL7QB/SL7Q8 too, so can we assume that any x64 Cpu has Sse/Sse2?
Or is there some Embedded/Low End x64 or so that has it disabled?

According to the search tool https://www.cpu-world.com/cgi-bin/CPU_Chart.pl
There are 98 Socket 754 processors with Amd64/Em64T, and the same number with Sse + Sse2.
And the same remark with the 178 x64 Socket 775 models.

Unfortunately. the tool does not have a "does NOT have xxx feature" criteria.
But I can see that there are 4482 x64, and only 4471 that have Sse or Sse2.
What could be the 11 x64 models that don't have Sse/Sse2? We can only see the first 100.
Or are they all mistakes in the database?

All Xeon Phi models (more than 11) except the very last three (Knights Mill) do not support sse.

Good catch, and I did not know that some Xeon Phis existed as an "usual" Cpu...
The search engine shows 14 x64 Xeon Phis and only 3 with Sse/Sse2, so they are the mystery 11 chips.

So, "x64 Cpu with Sse2" is not a pleonasm :p ...

Thank you !
