      I'm getting one as soon as I can find one cheap. The stock is limited right now in the US to very few shops and some like to only offer them in bundles. It will help with snes and arcade for sure.

        Now take away emulation processing power is it worth the upgrade. I would say alone for better wireless faster ethernet and a little extra cpu. if you are below a pi3 i would say yes its worth the upgrade for sure.

          I guess there's no improvement in shaders performance as well with the new model, because shaders are supposed to be handled mostly at GPU level. Anyone can refute this argument?

            Will get one soon.
            For me as a die Hard MAME Fan, 200MHz plus will help a lot! 😊

              I was watching Pimoroni's Bilge Tank this morning and they mentioned that it runs cooler than the original Pi3 so that could be a potential upside (if it runs cooler, you're less likely to suffer from throttling).

              The new one can do more despite being the same kind of processor because it doesn't get as hot. This is mostly because there is some metal on it that wasn't on the old one, which pulls heat away from the processor so it can work faster. Just like when it's hot you don't feel like doing much, processors also work better when they're cool.

              From: http://blog.pimoroni.com/straightforward-guide-to-whats-new/

              Well the CPU does have a heat spread on it this time which does lower the temps but for me i still would rely on using my dual fan on it.

                I would say no, at least for me personally. I'm already running Pi3 boards at 1350 MHz, so no need for 50 more MHz. If it turned out to be highly overclockable, then I might reconsider, but I suspect that is not the case. Aside from the nice addition of a dual-band WiFi radio and a slightly better NIC, they are basically the same as the original Pi3 (when it is overclocked). I will wait for Pi4 before I upgrade.

                  My pi doesn't overlcock at all ( think I managed a 15 mhz cpu boost). So the extra few hundred mhz will really help with knocking down the SNES control lag that pops up (assuming this is the CPU causing the issue but maybe the updated bluetooth will help too).
                  If I can get an extra 100 mhz out of it over the 3.4 N64 games might be mostly playable.

                    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.

                      I'm sure youll be able to overclock it. How much it will take is a different story.

                        Probably the same amount as the original 3B. The 3B+ has the same CPU, it just hasn't been throttled for the sake of temperature like the 3B. The RPi 3B with a heatsink and fan should have the exact same overclock potential as the 3B+ with a heatsink and fan.

                          @piboy I think you are a little off base. Most pi 3s will not Overclock to 1.4ghz. Mine will just make it to 1.35ghz and be stable, past that and I will get crashing and other issues. Heat isn't the main issue when it comes to stability.

                            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.

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

                                      @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.

                                        @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.

                                          4B ~ RPi PSU 5.1V / 3.0A ~ 32GB SanDisk microSD ~ 128GB USB
