Intel正在開發PCIe 4.0 SSD但仍需要用AMD CPU測試

Intel is prototyping PCIe 4.0 SSDs, but needs AMD CPUs to test them

Facepalm: An errant tweet has revealed that Intel’s second generation Optane
3D XPoint SSDs are being sampled to developers, with a new flagship feature: P
CIe 4.0 support. The only problem? Intel doesn’t have any CPUs that support P
CIe 4.0. Maybe AMD can lend them some.
Oh, the irony.

AMD became the first to support PCIe 4.0 with third-generation Ryzen. While at
launch the upgrade over Intel’s PCIe 3.0 was mostly academic, a slew of PCIe
4.0 SSDs have since been released with speeds almost twice as fast as previou
s generations. Intel’s CPU department might not have seen that as a big deal
but apparently, their storage division does.

Intel’s technical marketing performance engineer Frank Ober tweeted that Inte
l is willing to send out PCIe 4.0 SSDs to developers. But the developers will
need PCIe 4.0 CPUs to take full advantage of them.

In September, Intel confirmed the development of Alder Stream SSDs, an update
to their Optane drives that will use second generation 3D XPoint technology. 3
D XPoint is often marketed as a middle ground for RAM and solid storage. It’s
much cheaper per gigabyte than system memory with similar latency, but its SS
D-like speeds mean it can’t really replace RAM.

The next generation of XPoint focuses on enhancing speeds, according to Intel.
But if they want to double speeds, or, like Micron, triple them then they’ll
need either twice as many PCIe lanes (which no one would want) or to upgrade
to PCIe 4.0, which has twice PCIe 3.0’s bandwidth.

Intel wanted to build PCIe 4.0 support into a new architecture based on 10nm,
but they’ve been forced to delay that for years. It’s now scheduled to enter
production in late 2020, so if we cross our fingers and pray, we might just s
ee PCIe 4.0-supporting CPUs from Intel in early 2021. Meanwhile, they’ll be b
uying from AMD.

大意：Intel正在向開發人員推送新的PCIE 4.0 Optane固態硬碟

但目前Intel沒有支援PCIE 4.0的CPU，所以測試平台還是得用上RYZEN3

英特爾稱，下一代XPoint致力於提高速度。 但是，如果他們想將速度提高一倍，或者像M
icron一樣將速度提高三倍，那麼他們將需要升級到PCIe 4.0，後者俱有兩倍的PCIe 3.0
頻寬。

英特爾希望將PCIe 4.0納入10nm的新架構。 計劃於2020年末投入生產，因此，我們可能
會在2021年初看到英特爾提供支持PCIe 4.0的CPU。
但目前還是必須向AMD買U的
