CIOs Beware: New Macbook Pro Will Be a Bandwidth Hog

I kept the title honest but I submitted it specifically because the article says, "But it may also wreak havoc on CIOs’ networks and connectivity budgets — better quality displays require more network bandwidth, which allows users to increase data consumption."

How can the WSJ report such nonsense? Bigger displays do not increase bandwidth usage as far as I know.

It's page view trolling - I'd prefer not to have contributed a hit.

They might have accidentally stumbled on a real topic though - I've observed my iPhone bringing my home WLAN to a grinding halt with iCloud backups...

It all makes sense. Having a higher-resolution monitor increases the resolution of HD video! Somehow!

Thanks for the laugh. Wow.

The best I can come up with is adaptive streaming video. But I doubt anything streams higher than for output to 1080p and you certainly don't need a retina display matrix on a laptop to display 1080p.

There are sites that provide different images for different resolution devices. Bandwidth used when accessing those sites may in fact go way up when accessing from the Retina MBP compared to when accessing from a "normal" laptop.

People with expert knowledge in any field will frequently notice "wow, the media does a terrible job of understanding and explaining my field." Too few take the next logical step: the media does a terrible job of understanding and explaining almost everything. You simply notice the problem more in areas where you know more.

The media has gone from explaining stories to just sharing them. It's like a journalistic chain letter from hell.

   Hey! Did you see politician X's gaffe?

   Here is an interesting chart I found

While the WSJ should be embarrassed by a posting an article like this, I am glad that comments are turned on.

A few websites like Apple's are 'retina optimized' and the way Apple implements it, it is a bit inefficient--the web browser downloads the standard size image, then some js replaces those images with high-res variants. But sites like that are rare, and still don't account for a large amount of bandwidth used, so I vote: FUD.

>CORRECTION: An earlier version of this article incorrectly suggested that the higher resolution Retina displays of the new iPad and forthcoming Macbook Pro computers would increase consumption of network bandwidth, thus slowing performance of corporate networks. Higher resolution screens do not in and of themselves consume more network bandwidth. Some analysts have suggested that owners of devices with high-resolution screens will likely consume more video and HD video, which would result in higher bandwidth consumption. This article has been modified to reflect this change.

Still a stretch in my opinion.

The article is poorly worded. The point is that retina 2x graphics do require more bandwidth. As retina displays grow in popularity, bandwidth may become an issue. It's certainly something developers should consider when thinking about site performance.

One case where he could be a little bit correct is screen sharing a large desktop would use more bandwidth, but I doubt he was thinking that.

"(...) better quality displays require more network bandwidth, which allows users to increase data consumption"

Whaaat?

Seems like a Fox News writer got assigned to WSJ at News Corp.

I don't understand how the WSJ published this.

Wait a minute.. today isn't April 1, is it?

Not sure if trolling or stupid

As far as I know youtube videos at 1080p use the same bandwidth regardless of whether you're displaying on 720p or a retina display. This is silly, is the reporter confused about HDMI/DisplayPort vs. network bandwidth?

You really think YouTube is downsizing them in the front-end, rather than rendering out multiple versions on the server? That doesn't really make sense, plus it would make it odd that changing the size of the video restart the playback.

If the monitors are running off the network instead of DVI/HDMI/VGA/Display port, it's the CIO that must be fired.

The only way this can be an issue if everyone's running off remote access and running it at the highest resolution without compression.

I wonder if the WSJ would hire me to write about financial issues. I mean, I know nothing about the subject, but apparently that's not relevant.
