I don't think this inevitably follows. It means, for a web server, some requests will be faster than others, but some faster is probably still better than none faster. If you have a very specific need for consistency, then slower is better, but that's rather niche.
Do companies like google and Facebook replace 100% of their servers all at once? Or do they upgrade in stages, allowing some requests to be processed faster than others?
- wmf 4y agoFor most workloads the 7950X3D is slower and costs more than the 7950X. The performance variability is just icing on the cake. It's really a gaming processor.
- tedunangst 4y agoOkay, sure, median performance per dollar is a useful metric. I don't think variability alone is a deal breaker.
- cyber_kinetist 4y agoAnd if you really want to buy a gaming CPU then the 7800X3D is basically the same (or better!) performance for much less money.
- karussell 4y agoIMO the predictability, that a certain request for a single server should have the same response time, is very important to find performance regressions. I'm still unsure how others that use Hetzner deal with this: https://news.ycombinator.com/item?id=35165764 https://news.ycombinator.com/item?id=35165764
