I wish they'd integrate PoE (without the hat). That chip they're using appears to support it. http://www.trxcom.com/Product/product/id/353.html

It supports it in the sense that it provides the extra taps on the Ethernet magnetics for the actual PoE converter to connect to. That's all the onboard support they have, as far as I know - just the few extra connections required to feed the PoE hat which contains all the extra support electronics.

What is an AMD/Intel CPU as powerful as this RPi4 CPU?

Going by the "3x faster than Pi 3" claim it should be roughly on par with desktop CPUs from around 10 years ago (Core 2 Quad Q6600, Athlon II X4 600e) or the modern quad core Atom CPUs like say the x7-Z8750.

I have a 4K-capable 40 inch TV in a standard living room (for Europe). 4K videos look slightly crispier than full HD ones. While I could have a slightly larger TV, I think that for typical domestic use 4K's improvement is marginal because people are not sitting 50cm from the screen and room sizes are limited. Really, so far the top benefit has been that I could tell my wife: "Look, if I move right up to the screen I…

A 40 inch TV is on the small end for 4K having any real benefit (at least at a normal living room viewing distance).

I'm still struggling a bit with large screens. For something like playing games I'm guessing you can comfortably sit back. High resolution screens for computers feel attractive, but getting up close and personal can feel a bit much with light levels. I'm guessing OLED might be nicer in that regard.

Gigabit Ethernet? I'm tempted to grab a few and try running Pi-Hole for my whole organization (~1200 users) and see how that goes. :) I know you can set up Pi-Hole on Ubuntu VMs. But there's something so attractive to me about running it separate from your hypervisors and closer to the core switch on very very cheap hardware.... Been curious about Pi-Hole on my bigger work scale for a while, this may very well tip me…

I've been running Pi-hole on Ubuntu on bare metal for a few months. ("server" in my basement)

What's the thermal story? Looks pretty terrible so far. The case has no holes. The board has no holes for the heatsink, so you'll have to glue it. Space for heatsink is small. Is it made so that the board serves as a heatsink at the very least?

>The case has no holes. Uh, give it five minutes and there will be 13524 third party cases?

I don't care about other cases. I care about what the vendor's case suggests. That is that this chip either runs quite cool (so creating a worst case scenario with a fully closed case doesn't matter), or that they don't care about the cooling for some other reason.

I somehow doubt a chip with a heatspreadder is meant to run cool, though. It looks like they're sacrificing performance here.

For those of us who aren't there, can you clarify how big a standard European living room is? This has nothing to do with the resolution stuff you mentioned, just curious.

In the UK in a victorian terrace, and our front room is perhaps on the small side at about 3x4m. I'd guess somewhere between that and 4x5m is about average. For us 32inch still can feel imposing. And that size screen seems to be being phased out.

Oh dear God that's tiny. How do you stand that? Genuinely curious; I feel like I'd end up claustrophobic.

This is the death knell for x86 PCs for the consumer market. No regular user needs more than this. Developers and hardcore gamers will be the only ones left on x86. Intel will be a shadow of themselves soon. They have did such a bad job at diversifying.

Until you launch an Electron based app, load Gmail, or go to an ad-laden webpage.

It might be a better idea to develop those apps on one of these, instead of using Macbooks + the cloud.

I'm super excited as well. I figured out the secret sauce to get a low latency kernel build I was able to get down to 20ms latency but I'm excited to see if this can't get down to 10ms even though 20ms is acceptable low audio latency, already with only 1 gig of ram on a pi3 ardour is usable for multitrack recording, excited to see how this does with 4 gigs.

Forgive me, but isn't 20ms kind of a lot of latency? That's more than a frame at 60hz. I assume I'm missing some context here.

We do have another room, that's slightly larger but it's a bit bleak. And weirdly it's a more fussy room to furnish. The smaller size is better in the winter. The old brick terraces aren't that warm. In large houses people can gravitate to smaller rooms for that reason. Personally I'd like a large room that I could bring the furniture in from the sides. Lucky to even have a house to live in to be honest, so can't really grumble.
