ARMv7 has a SIMD unit (NEON) that easily outshines SSE and Altivec. Floating point support is also good nowadays.

- DarkShikari 17y agoOr, better said, the instruction set NEON outshines SSE and Altivec. The actual vector unit is a bit lacking performance-wise by comparison, which shouldn't be particularly surprising given that it runs on 100 times less power.
- mru 17y agoTrue, but there's nothing to say future implementations will not be faster. Adding more execution units is "easy". Fixing an instruction set is not.
