[中央處理器] 有冇人等緊Intel Optane 3D XPoint記憶體模組

Intel Optane係為Kaby Lake或之後處理器而生, 雖然容量只有16G同32G, 而且價錢仍然係未知之數, 不過佢可能係Intel秘密武器嚟應付對手新處理器. 係HKEPC有冇人都等緊Intel Optane?

仲有冇人記得Pentium年代既256KB/512KB Pipeline Burst Cache模組呢?

PCIe 3.0x4限制咗速度.....呢隻嘢係屬於PCIe 4.0嘅

It's speed is close to RAM.... crazy item.
In future... no more storage and RAM , all in 1 single "Memory" pool, no more page file ... so good.

網上見過展示產品係M.2模組封裝, 售價不明, 希望唔好天價開買啦.

係latency方面, Intel Optane只係追近RAM, 除非佢能大量生產及降價, 否則好難取代RAM.

其實Ram speed係咪bottleneck,
3d xPoint有冇話大概等同幾多年前嘅ram speed

last time I forgotten where read about the speed compare RAM, which just around 15 to 25% slower only.

yes, price can be much common like current sata ssd by future mass production.

maybe next gen big version OS change will see the overall architecture change

點解?PCIe 3.0 x4有3940MB/s
而且960 pro 可以去到34xx MB/s

Sorry for my bad memory, it should not that fast for 3D XPoint peformance, but, it's main selling point is the extremely low latency , which "closer" to DRAM.
