Good question indeed.

Isn't Intel HD4000 several times faster than any currently available GPU in any ARM SoC? The only reason to use ARM SoC is low power consumption.
Honestly I don't see why would someone spend nights...

Not for fp math, but it might be used to speed up memory move/copy (by using 128-bit registers).

I think you somewhere missing the point. SSEx now is a full replacement for old and outdated x87 in all respects and this is the reason why it should be used for testing in 32-bit systems also. x87...

Instruction latency is only part of the story. Even if we put aside potential vectorization, using SSE over x87 should produce denser code because of the better register availability which should...

SSEx is default fp instruction set for x64 Operating Systems. Also scalar SSE is much faster then outdated x87 and should be used over x87 when possible. ARM neon can not be compared to SSE at this...

Just found it. Atom & Ubuntu x64

I think that there is a problem with the test profiles for x86 cpus. gcc does not generate SSE code w/o -mfpmath flag set to SSE. So in 32-bit linux system the x87 code path is used by default. I...
