Intel正在开发PCIe 4.0 SSD但仍需要用AMD CPU测试

Intel is prototyping PCIe 4.0 SSDs, but needs AMD CPUs to test them
By Isaiah Mayersen on January 5, 2020
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正在向开发人员推送新的PCIE 4.0 Optane固态硬盘
但目前Intel没有支援PCIE 4.0的CPU，所以测试平台还是得用上RYZEN3
英特尔称，下一代XPoint致力于提高速度。 但是，如果他们想将速度提高一倍，或者像M
icron一样将速度提高三倍，那么他们将需要升级到PCIe 4.0，后者俱有两倍的PCIe 3.0
频宽。
英特尔希望将PCIe 4.0纳入10nm的新架构。 计划于2020年末投入生产，因此，我们可能
会在2021年初看到英特尔提供支持PCIe 4.0的CPU。
但目前还是必须向AMD买U的
