I'm not sure if I got you right: The performance boost with speculative execution is massive. It introduces a vuln. It is the fix for that vuln that kills the performance.
- Popegaf 5y agoWhat I'm saying is if the fix for the vuln negates the performance boost from speculative execucution, then the net outcome is 0 performance boost and speculative execution might as well be removed entirely. It wouldn't surprise me if it just costs more energy to keep the vuln and mitigation active at the same time.
- SAI_Peregrinus 5y agoThe fix doesn't negate the performance boost. It decreases it. But it's still nonzero boost.
