If you read the top comments, you will see (as in the article they also mentioned),
they chose "A small database that can be mostly cached in the L3-cache", which is largely not true for realistic sc ...

Not sure, but if as comments mentioned (I don't know much about database) a real-life model requires data stored mostly in RAM,
EPYC has a much better bandwidth comparing to Intel's.



So it is inte ...

AMD 呢次玩膠水8春反擊到Intel 無曬法子咁既？
又睇下威到幾時？
當年AMD 都係係K8 對P4 2.8e 果期叫好左一陣
C2D 一出就死直
果度三年唔夠

之前仲有K7

不過Intel駛橫手
