Are you sure? I recall cmov always having single cycle latency.

Are you sure? I recall cmov always having single cycle latency.
- BoardsOfCanada 2y agoI know that it was decoded into 2 micro-ops and thus had to be decoded by the wide decoder, so perhaps 2 cycles?
- clausecker 2y agoThat could be. Agner's tables seem to confirm that.
- jnordwick 2y agoPer Fog's tables, Ice Lake shows a reg-to-reg cmov decoding to 1 uop with a latency of 1 and throughput of 0.5. *mont all have latency 2. P4 had a latency of 6. AMD's K10 latency 4.
