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?

I have a Raspberry Pi 4 Model B in front of me and have just run some benchmarks using the Phoronix Test Suite. TL;DR: Prime CPU test; Pi4B: 60 seconds, Pi3B+, 80 seconds, Render test: Pi4B 27fps at 720p, Pi3B+ 16fps at 720p. Zips of the test reports: http://cdn.littlebird.com.au/rpi4/test-4-b.zip http://cdn.littlebird.com.au/rpi4/test-pi-3-b-plus.zip

Hi, thanks for running this. It's helpful information. Something strange is that in your cpuinfo the SoC is detected as BCM2835, while in all the spec sheets online it's supposed to be BCM2711. Do you know if you are possibly working with a different version of the hardware? One reason this is important is that some of us in this thread are trying to work out what the video decoding and 4K HDMI capabilities are with…

BCM2835 vs BCM2711 is all in software, the board itself doesn't tell you explicitly.

The regular vc4 drivers are just an rpc to the code running on the GPU with start.elf. I wouldn't be surprised if the old drivers just worked.

Depending on the purpose, for example if somebody just wants a compact home cloud, the Odroid HC2 could also - still - be considered: https://www.hardkernel.com/shop/odroid-hc2-home-cloud-two/ - Half the RAM but double the cores. I'm waiting for some benchmarks to see if the RPi4 is faster and by how much. - Also Gigabit Ethernet and it works great. My downloads are always at 108-111MB/s for the whole transfer. - Not…

Can we just start calling them servers again?

Can't wait to buy this, boot it up, play with it for four hours, then stick it in the same desk drawer with the other Pis I have bought over the years. (The upgrades look great, just my attention span is not so great)

Right? The most use one has ever seen from me was about 3 hours of playing SNES roms until I realized it was distracting me from Netflix.

Oh my! This is such a crazy upgrade. I've been using the RPI2 as my HTPC/NAS at my folks, and I'm so happy with it. I was itching to get the last one for myself. USB 3.0! Gigabit Ethernet! WiFi 802.11ac, BT 5.0, 4GB RAM! 4K! $55 at most?! What the!? How the??! I know I'm not maintaining decorum at Hacker News, but I am SO mighty, MIGHTY excited! I'm setting up a VPN to hook this (when I get it) to my VPS and then do…

> I've been using the RPI2 as my HTPC/NAS Using the Pi as a file server can be a bit flaky. The ethernet controller was an USB one, and was neither really stable or took load very well. The new PHY on a dedicated link is probably the single biggest improvement with this new revision. The HEVC is a bit unexpected considering the high license fees and general uncertainties. Let's hope the documentation can be released…

The HEVC codec may well be an additional cost for CODEC license as is the case with VC-1 and MPEG2(though that expired!).

So unsure at this stage, but that may well be the case for any license fees regarding HVEC. Heck, if they have absorbed those costs into the base price - I'd be utterly amazed.

Thanks--there have been enough April Fools videos of supposed Raspberry Pi 4s that when I saw one this morning, I was suspicious.

I fell for one of those videos last week... Didn't notice it was April fools until I went back this morning, confused. Guess I need to stop letting Youtube pick the videos I watch.

> Gigabit Ethernet! Does it have PoE? Having to deal with one less cable would be nice. Especially given that the latest spec, IEEE 802.3bt from September 2018, now allows for up to 100W per port: * https://en.wikipedia.org/wiki/Power_over_Ethernet

did they finally release the 100W spec? IEEE really let that spec languish for too long -- vendors got impatient and implemented their own. i had to write 60W PoE code supporting three different specs around 2015. bosch's design was the worst.

Uh, give it five minutes and there will be 13524 third party cases?

Earlier quoted context omitted.

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…

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.
