AMD
在AMD的7nm锐龙3000及X570芯片组上,PCIe 4.0是一项很重要的技术,高达32GB/s带宽
相比现在的PCIe 3.0技术翻倍,AMD的RX 5000系列显卡及群联、慧荣主控的SSD硬盘将
加入PCIe 4.0支持。
从台北电脑展到现在,PCIe 4.0主控的SSD硬盘已经不下七八款,其中使用最多的还是
群联的PCIe 4.0主控PSE5016-E16。群联PS5016-E16采用28nm工艺制造,支持最新的96
层3D TLC/QLC闪存,八个通道,最大容量8TB,集成第四代RAID ECC、LDPC纠错引擎,
拥有独家专利的硬件加速器设计,理论读写速度最高分别可达5GB/s、4.4GB/s。
不过目前PCIe 4.0主控及硬盘还没有彻底发挥出PCIe 4.0的带宽,理论上性能应该可以
达到7GB/s。要想达到PCIe 4.0 x4带宽的满血性能,还要新一代的PCIe 4.0主控,这个
事还得群联自己解决。
日前群联公司表示明年Q1季度将推出新一代PCIe 4.0主控,速度有望提升到6500MB/s。
这个速度相比目前的PCIe 3.0主控硬盘来说几乎翻倍提升,比现在5000MB/s的PCIe 4.0
硬盘性能也提升了30%以上,几乎逼近PCIe 4.0 x4带宽的极限了。

Wrapping it up in a person:
Examining employment and earnings
outcomes for Ph.D. recipients
Nikolas Zolas,1 Nathan Goldschlag,1 Ron Jarmin,1 Paula Stephan,2,3
Jason Owen-Smith,4 Rebecca F. Rosen,5 Barbara McFadden Allen,6
Bruce A. Weinberg,7,3,8* Julia I. Lane1,5,8,9,10
In evaluating research investments, it is important to establish whether the
expertise gained
by researchers in conducting their projects propagates into the broader
economy. For eight
universities, it was possible to combine data from the UMETRICS project,
which provided
administrative records on graduate students supported by funded research,
with data from
the U.S. Census Bureau. The analysis covers 2010–2012 earnings and
placement outcomes of
people receiving doctorates in 2009–2011. Almost 40% of supported doctorate
recipients,
both federally and nonfederally funded, entered industry and, when they did,
they
disproportionately got jobs at large and high-wage establishments in high-
tech and
professional service industries. Although Ph.D. recipients spread nationally
, there was also
geographic clustering in employment near the universities that trained and
employed the
researchers. We also show large differences across fields in placement
outcomes.

【在 b******e 的大作中提到】
: 如果想放东西在床下面,需要床脚高,这样的床美国有卖的吗,
: 叫什么名字,还是要去叫木匠定制?

这不屁话么?也不分析下原因啥的?赶明儿统计下发考题们不同学科不同年龄段的性生
活吗频率也能发science了

别不服,现在博士多如狗,千老满街走。很多高学历人收入还不如妓女,街头毒贩。研
究博士和千老的工资,社会地位,心理状态,等已经成为了经济学,社会学,心理学等
领域的热门话题。
Science 要的是引用率,发这篇文章,它做到了。
