Pi3+ - worth upgrading to?

tikiandskull

i reed that in the recalbox forum by a man named "gkralicek2"

"Overclock works fine with new pi 3 B+ (i tested it briefly this afternoon with raspbian). I managed to achieve a 200 Mhz bump (from stock 1.4 Ghz to 1.6Ghz) without any problem on all of the 10 unit we got for test in the lab where i work. Idle temperature at 1.4Ghz is somewhere around 56-58 celsius and it climbs up to 68-70 once overclocked @1.6Ghz (which turns out to be closer to 78 degrees once a few stress tests are executed). Much better than the results i got with the original Pi 3 with copper heatsink when overclocked from 1.2 to 1.5 (which was slightly above 80 Celsius at times hence provoking random freezes).

I'll try to do some more tests if i got spare time during the next few days trying to get close to 1.7 Ghz if possible (but as far as 1.6 gets me close to 80 degrees i'm afraid pushing more will end up in random freezes)"

This sound like its time for me to update my pi 2 a pi 3 wasnt worth it the extra networking + the extra speed justifies it for me if i was on a pi 3 i wouldnt do it to be fair

Makes me wonder how well it would perform if a sink was added to the spreader. Or if the flirc case gets a redesign to fit it.

In my opinion it's worth the upgrade considering the low price of the device but only if you're running lr-snes9x, lr-pcsx-rearmed and lr-mupen64plus.

Overcloking my 3 model to 1.4GHz decreased some slowdown problems of the above RA cores (especially sound clicking issues with lr-snes9x/lr-snes9x2010) but I have to use copper heatsinks and a little fan.

I believe that the stock clock of the B+ model will eliminate the need for any kind of cooling parts while the 200MHz boost seems to be quite useful for the aforementioned optimisations.

BobHarris

@matchaman Did you only overclock the cpu when you saw the improvements in these cores?

Jono

@drake999 ETA Prime posted some benchmarks today, he got the 3+ to go to 1550Mhz, and he clocked the GPU to 500Mhz. He said there was no noticable improvement in games, a slight improvement but GPU is the bottlenext at the moment.

sirhenrythe5th

@jono spoken for what kind of games?
Sounds like Dreamcast, N64 & Co.
Concerning MAME an Upgrade of 350MHz will be more significant.

I feel like I'm reading conflicting things regarding power consumption of the Pi 3b+. I (think) I've read that it runs at a higher Mhz with higher power consumption and cooler temps? Is this correct? Can someone possibly ELI5? Would I need a new power supply other than a 5V 2.5 A supply? Thanks!

Edit: This power consumption article was just posted on another thread.

matchaman

@bobharris yes, only the CPU OC helped to eliminate the lr-snes9x/2010 clicking

Jono

@sirhenrythe5th sorry for not getting back sooner. You're right, he was talking graphically intensive games such as Dreamcast and N64.

Well I can't really recommend spending the money as an UPGRADE. However if you're going to buy a Pi soon anyway go for this one. Here's my $0.02:

First off I have never O/C'd the 3B and I am not doing it to the 3B+ either so stock 1.2GHz and 1.4GHz respectively. The RAM is the same at 1GB and the GPU is the same as well.

Right out of the gate: I guess a small 200MHz increase can make a difference. :)

Boot times (started timer as soon as I pushed the power button):
3B+
32GB card and RetroPie 4.3.15 image only - 24sec
32GB card and 256GB USB (90GB used) - 1min 45sec

3B
32GB card and RetroPie 4.3 image only - 25sec
32GB card and 256GB USB (90GB used) - 2min 4sec

PS1 Destruction Derby 2 and Gran Turismo 2 ran flawlessly as long as you didn't use vibration feedback. On the 3B I would get a frame hesitation here and there - extremely minor almost not worth mentioning. On the 3B+ there was nothing TO mention. I saw nothing in multiple races. Smooth running. :)

The scraper did MUCH better on the 3B+. Last time I set up I used the built-in scraper from the menu and scraped 41 Playstation games. I watched an episode of Friends on Netflix and started a 2nd before I finished. On the 3B+ I did all of them in 5min 27sec. The WiFi is vastly improved on the 3B+ and it shows.

PING yahoo.com on 3B: avg 65.405 ms with 20 packets sent 0% loss
PING yahoo.com on 3B+: avg 32.190 ms with 21 packets sent 0% loss

On a personal note I have 2 PS3 controllers - one white and one black. I already paired the black one with the 3B. I left that alone and paired the white one with the 3B+. Nice to have and easily differentiated!

@dirthurts I was getting lag with input as well, and I ended up resolving it by switching to a USB bluetooth dongle. Perhaps the bus that the built in bluetooth gets over saturated? Not sure, but using a dongle resolved this for me. The input lag was especially prevalent with more than one controller present.

pjft

@kookamunga what controllers do you have? Are you using the PS3 controller drivers?

sirhenrythe5th

@pjft i use Dualshock 3 without divers since 3B+ and MortalKombat-Tournament-Sticks (also PS3) via USB.
No Problems so far.

Not working are the Streetfighter 4 Tournam Stick from MadCatz for the PS3 and the NeoGeoStick 2+ also for PS3.

@classicgmr Meh, boot times don't matter much between pi's once tweaked. Once I run some (not all) tweaks from https://www.evernote.com/shard/s3/sh/38bf9df7-5f96-4451-90e7-7d72c07f225b/8d57114e589b5a39147ffd9d6c5df1e0 and uninstall some stuff like usbmount, plymouth, dhcpd (I set a static ip), my pi3 non + with 128GB (like ~80GB used) USB stick boots to Pegasus (the frontend I use) in around 15-18sec. I'm using the stretch retropie image. I'l l be getting my + on friday :D

I did notice usbmount added a bit more of a boot time on stretch vs jessie, but it's just an observation from a linux noob like myself. I grew up on dos/windows in the 90s so I'm slowly catching on.

pjft

@sirhenrythe5th me as well, hence the question. On Jessie I was having a lot of lag with the ps3controller drivers.

sirhenrythe5th

@pjft me too, so i never used them wireless on jessie 😉

pjft

@sirhenrythe5th to be fair, @psyke83 's done a fantastic job backporting bluetooth drivers to Jessie (there's a thread about it), and those worked perfectly for me.

drake999

@jono Yeah that is what I suspected. Since there is no improvement to the GPU and I only emulate up to PSX with enhanced resolution, my standard Pi3 works fine for what I'm doing with it. I higher CPU clock than what I've already got with overclocking and cooling will be of no benefit. Here is hoping the Pi4 gets an updated VideoCore V GPU or something. I'll hold out and see what they have in store for the Pi4.

I could tell you my setting if you want to but i broke all of the warranty. You also need a fan.

Apparently, the raspberry pi designed for 1.4 Ghz and then they lowered it to 1.2 Ghz to get rid of a heat issue.

I dont think the 3B+ pi can be overclocked... it would be nice to get rid of the fan situation. And I dont need to break any of the warrenty.

There is people that are overclocking it to 1.5 - 1.6GHz already which runs a little smooth but still needs a fan cause i believe when it was around 1.6GHz it was getting like 75°c.
