AMD announces the $699 Radeon VII: 7nm Vega, coming February
New card should close the gap with Nvidia's RTX 2080.
The GPU inside the VII is called Vega 20, which is a die-shrunk version of the Vega 10 in the Vega 64. The Vega 10 is built on GlobalFoundries' 14nm process; the Vega 20 is built on TSMC's 7nm process. This new process has enabled AMD to substantially boost the clock rate from a peak of 1564MHz in the Vega 64 to 1,800MHz in the VII. The new card's memory subsystem has also been uprated: it's still using HBM2, but it's using 16GB clocked at 2Gb/s with a 4,096-bit bus compared to 8GB clocked at 1.89Gb/s with a 2,048-bit bus. This gives a total of 1TB/s memory bandwidth.

A sampling of networking gear from CES: TP-Link goes Wi-Fi 6, D-Link goes 5G
CES isn't all about voice assistants—but naturally, these routers have Alexa.
*The halls of CES might be filled with voice assistants and OLED televisions, but few things make a bigger impact on your day-to-day experience with technology than your networking solution. And there were a bunch of announcements on that front this year.

With a Qualcomm SDX55 chipset, five Ethernet ports (1x 2.5Gbps LAN, 3x 1Gbps LAN, 1x 1Gbps WAN/LAN)
What are 2.5 Gbps LAN?

It's a WAN port for multigig internet

I have previously heard of these but I have not heard that they got IEEE recognition yet.

Thanks - Of course I've been wondering why 10Gbps wasn't just becoming the norm (I'll come back to that), I now understand because of Cat 5e and Cat 6 cabling the reason for these new speeds.
But
Spain commented that today, 10 GbE is more prevalent in data center networks and campus backbone. He added that as 10 GbE technology matures, it will also be seen as an access technology.
isn't 10 GbE already mature?

So the rational and push for this was because businesses didn't want to make the spend for upgraded infrastructure. Who the hell does?!
Summary of the article:
We came up with this standard to have better usable life out of CAT 5e, where people are too damn cheap to rip and replace.

Does anyone know - can 10 GbE only run at 10 GbE? i.e. it can't clock down to 2.5 or 5 Gbps?

Right now I would say no because there’s no standard for those other states. Once there’s a standard and drivers are updated there’s no reason it could not
-
So this is the 2nd to last line in the article.
The new NBASE-T is now working towards addressing the industry’s need for supporting higher speeds on existing cabling infrastructure.
Why hasn't the goal always been to get better performance from the same infrastructure?

You read to much into my question.
Can 10 GbE clock down to 1 Gbps? I suppose even if it can, what would be the point? my thinking with the question was - who cares about making a 2.5 or 5 Gbps standard (mainly because those are able to run over Cat 5e and 6) just run 10 Gbps over 5e and run at 2.5 or 5.
Hell - why not update the 10 GbE spec to do just that? Seems like it would be a lot better than making whole new spec and another SKU, etc. Then we could just deploy 10GE everywhere and it will use the best speed it can that the cable can provide.
I'm wondering if there was some other limitation in it? I can't imagine that a 10GE port costs more to manufacture than a 2.5 or 5 GE port.

My guess is that "they" were only looking at the DC, and not the end user/end point connections. The cost of recabling a DC (while also replacing the NIC cards to go 10 GE) is likely a no brainer... it's clearly different when you're talking about end users/end points.

Just a standard LAN port, but faster.

The big driver was "cheaper hardware."

What makes it cheaper, specifically? do you know?

On copper, 10gbe requires cat 6A to go 100 m. On regular cat six you could maybe go 50 m if it types out well. That is not enough for almost any office.

To make sure it can always update, Windows 10 will reserve 7GB more disk space
It reserves the space all the time because it needs it some of the time.
The latest Windows 10 Insider build, number 18312, introduces a new feature wherein the operating system reserves a big old chunk of disk space, effectively expanding its on-disk footprint by another 7GB.
*The storage reservation is to ensure that certain critical operations—most significantly, installing feature updates—always have enough free space available. Windows requires substantial extra disk space both during the installation of each feature update (as it unpacks all the files) and afterward (as the previous version of Windows is kept untouched, so that you can roll back if necessary). Lack of free space is one of the more common reasons for updates failing to install, so Microsoft is setting space available on a long-term basis, allowing those periodic updates to be sure they have what they need.

Well if most of their users aren't planning for this, MS has to plan it for them. Makes sense.

@mlnews The Windows platform as a whole is just becoming more and more bloated and needy rather than becoming more streamlined, efficient and powerful.
