Do Processors with SSE4 support also support SSSE3?

[HMcKe]

Is instruction set extension support cumulative? I assume so, but so far can not find a definitive statement that it is.

Hi HughMck,

Most of Intel® technologies have backward compatibility. Could you please provide your processor model? Regards,Hellen.

Hi Hellen,

Thanks. That's largely what I had assumed.

There are two processor models I wanted to know about: i7-4790 and i5-4570.

Best Regards,

Hugh.

Hi HughMcK,

Since both include SSE4 and AVX, they might have backward compatibility and should work. Please let me know if there is something else I could do for you. Regards,Hellen.

Hi Hellen,

No other questions just now. Thanks.

Hugh.
