I bought it. But then again I have a horrible pi addiction. I need help.
Pitervention is required.

@tiagop Its only a 0.2 Mhz bump in clock speed. Don't get your hopes up for improved emulation. You'd have to wait for a Pi 4 if you want a significant bump.
-
@lilbud 200Mhz :-) or 0.2Ghz
-
@lilbud Oh yeah, my bad. I thought the RPI3 had 1.0 GHz instead of 1.2 GHz!
-
Me too. This morning's order will bump me up to 11 pii.
-
Will the Pi3 b+ work with retropie 4.3 or will there need to be support added?
-
@herb_fargus I'll join you are RPi Anonymous :)

This one is all about overclock. 1.4Ghz is what most base Pi3s are able to achieve whilst remaining stable. Considering the new model’s base speed is already 1.4, it should hit 1.6 comfortably, perhaps even 1.8 taking into account the better “thermal management” and the use of a heat sink+fan little combo. On these terms it’s actually a rather decent upgrade over the base model with stock clock.

I am not so convinced of that. The original RPi 3 is underclocked for the sake of overheating. The clockspeed on the 3 B+ is now at the original speed for the CPU, 1.4 GHz, and features a heat spreader to mitigate overheating. According to the RPi's site, above 70°C it will throttle down to 1.2 GHz, and above 80°C it will throttle even lower, just like the original RPi 3. There does not appear to be any indication there is a higher overclock potential, considering you will still need a heatsink/fan combo anyway when overclocking. People who overclock the current RPi 3 still hit somewhere between 1.4-1.6 GHz, with a fan. That speed increase doesn't make a big difference in terms of emulator support, in case you were wondering. N64 is still not tenable.

It looks to have a real IHS on the CPU. Metal on metal cooling. If the emulation is CPU heavy overclocking the GPU probably won't gain much but a GPU heavy game might benefit a little from overclocking the ARM and both may potentially benefit slightly from RAM overclocking.
-
Damn, I have a Pi1B and a Pi0, convinced myself that a Pi3B would only bring PSX from playable to nice and N64 from not playable to sometimes playable. Expected Pi4B in February 2019.
Now I am quite tempted ...

I did't know that. Bummer...

I was reading an article about the improvement in "manufacturing" techniques allowed the Zero to be released stable at 1GHz where as the same chip 4 years prior on the Pi 1 was only stable at 700MHz.
Maybe in the past 2 years they were able to do the same between the 3 and + and get it stable at it's full potential. Which means less overclock room. I imagine vcore specs are basically the same. Which adds speed which in turn adds heat.

N64 is still not tenable.I wish I could get my 3 over 1.4. Anything past 1.35 ghz spits out memory errors during cpuburn. Even so N64 emulation seems to have bigger problems than simply throwing enough raw power at it.

I think we both need help. LOL

This looks cool, I might look into it.

Have one in my hands already thanks to the BuyAPi.ca folks who ship all their gear from here in Ottawa, and offer a pick up for local orders. I spotted the new product first thing this morning and they happened to be on my way this afternoon to pick up the kids. Let's see if my wife notices the purchase on our credit card :)
I'm an intermediate user I suppose... but one question before I check it out tonight: is this as simple as swapping the card from my current Pi into my new 3B+? I figure I'll run an update and then a backup before I pull the card.
If it's that simple, I can try tonight and see if there's any difference in N64. My son plays one of the Star Wars games which sputters a bit, and the audio really isn't worth listening to at all. Any improvement there is where I'd look for a quick test.

I was looking at ordering one just a moment ago until I read it needs the latest version of raspian for the WiFi chip to work.
With retropie still being Jessie then surely this will not work.
I'm curious and now holding off purchase until someone can confirm if the WiFi works on retropie. -
@ohmycommodore I don't think its that easy.
You'll have to use a different version of Retropie that is still in beta.

How does the PoE header give us anything powering through the GPIO doesnt already? Does it provide greater power to the USB ports than the old 3B? And why was it not integrated into the onboard ethernet jack?
