@licson u like the new Cascade Lake?
epyc真係同cloud computing天生一對
又唔會🙈
升到G07定唔記得係G08先有得行Scheme A
intel: you have been slained
原來唔NAT 隻1921射完野比上游之後個packet唔識返黎。。。
諗多左
1.schem A/TE 係G7有資格舉手,但唔係唯一所需資格。因為佢會問你老細,而唔係你嘅意見去報名。舉完手要去考試,大概一年200個人爭6個位
2.GT凍左年嫁啦,前年已經17k.G06就包底,但加幅應該得返11-13%,07早兩年都仲會條team包到底有07,但加幅你預8-10%。預2萬多就...
至於M step, E step, G step唔同價係正常
Yes, 仲有Internet connection
Pretty good, but now Intel and AMD are all using glue technology
Though Intel' UPI glue is more superior than AMD's Infinity Fabric
glue
Intel: two die glued with UPI (better glue w/ less NUMA domains)
AMD: 8 dies glued together with Infinity Fabric (worse glue, many NUMA domains)
我唔係 Intel 粉,不過經驗告訴我 Intel 嘅膠水(雙路配置其實已經有膠水)無 AMD 嗰啲麻煩野
佢個io core將全部glue blackbox晒
嗰啲膠水係舊 architecture 叫 FSB
依家 Cascade Lake 嗰啲係新膠水叫 UPI
後尾 Nehalem 出左 QPI 就冇左呢個問題,個陣 QPI bandwidth 實際有 25.6GB/s
一代 IF 每條 lane 個 Bandwidth 得 56Gbps(細 B)
yay, < 0.5 hkd/gb ssd will be dreammmmmmm
