Re: Raspberry Pi 4B 2GB Price Drop - NOW $35

A 8GB model @ $55 will be nice, when it makes sense to make one. Right now it's too pricy it seems. And so it's not made, anything else would be silly. There's naturally always an usecase for more RAM, that has nothing to do with something being badly written, of course. Bigger datasets to crunch, b...

Re: RPi 4 heat sink

I'd suggest to run your intended work loads on it, and monitor the CPU temp with:

Code: Select all

vcgencmd measure_temp
If it won't go over 85 deg C, your Pi won't throttle and you've saved yourself a couple of bucks.

Re: New Pi 4B v1.2?

I haven't analyzed the USB C connection and have no original thoughts on the matter right now, but after creeping though scorpia's post history I'm guessing this is what he's (?) worried about: scorpia: Also the 5v on the connector is connected directly to the 5v rails.

Re: Raspberry PI 4 - USB Boot

A bit off topic here, but speaking of stickies. There is kind of a lot of them.

How about taking some time, when it's apropriate, to discuss amongst the mods which ones to keep and which ones to let go?

That "USB boot now working on Pi3" one feels a bit crusty... but perhaps that's just me?

Re: Raspberry 3B slow.

Are we talking about a gradual slowdown, in what time frame does this happen? When it slows down to the point where you feel that you must reboot, it's everything just dreadfully slow or are some things seemingly not responding at all?

Re: Reasoning behind dual Micro HDMI, and potential future alternatives?

I don't think they'd want to sell at $60 a pop. It'd open up for all kinds of bad goodwill and speculation.

Imagine the hubub if they'd sell a plain Zero with a DSI connector (instead of the CSI) for $60, or even $20.

I suspect it's an euphemism for cheap. (That said, taobau, but then you need to import it of course)

Re: Raspberry Pi Zero - Version 2?

My meditations on the subject is that you want to make a bulk Zero at a sustainable price, and then be able to cut down costs for the limited purchase Zero. And make the bulk Zero attractive enough to make people struggle a bit. Like, the 5$ version has less RAM, and maybe it has got some connector(...

Re: RPi 4 audio bit rate and sample rate

You ask about HDMI and Odroids and RPis in that forum, and that guy answers about I2S and Odroids.

He never answered your question, and he never said anything about RPis.

And you doubt the commit in GitHub because of what reason?

Re: RPi 4 audio bit rate and sample rate

So the question is, has the bandwidth of the I2S bus increased on the RPi4? No idea, if I'd guess, I'd say no? (That said, a purely AC signal benefitting from a 32bit DAC ... or any signal really ... is highly suspect. As is the bandwidth in relationship to human hearing. But my thoughts on what I p...

Re: will the price of a RPI zero change after Brexit

The only bump in the road that I can think of being reasonable (for Pis) is if Sony gets tired of their plant in Wales (no idea what the revenue share of RPi is). But I'm on the other hand almost sure that such a bump, if it'd ever materialize, would not be noticed by consumers.

Re: RAM speed

SRAM is pricey in the sense that it eats a lot of die space, that could have been spent on other things, like a bigger GPU. But the only way I see SRAM comming to a future RPi with a new SoC, is if it's decided that it makes sense to include microcontrollers in the SoC. And then we're, at maximum, t...

Re: RAM speed

What are you looking for?

Latency of the chips? Practical latency for the CPU?

Theoretical bandwidth, practical bandwidth (running what code?)?

Practical benches can be found here and there a Google away. Tom's did a nice test of the 4 iirc.
