Video : Review of the Raspberry Pi4B - It's a monster...
Hi all.
I've made a review video about the Raspberry Pi 4B. Here it is. https://www.youtube.com/watch?v=u2rDYDv-BwA&t I've found out some nice things I didn't see in any other review videos. The performance is great, ram is so much better, USB3, gigabit ethernet... But it also has some problems, still undervolting with most PSU's. You need a heatsink+fan for good performance. Here all my test results. Greetings, NicoD Raspberry Pi4B -------------- Raspbian Buster --------------- Blender results Default clock 1.5Ghz No fan Tinker heatsink : 1h57m23s 3v fan Tinker heatsink : 1h29m07s OC clock 1.75Ghz 3V fan : 1h19m25s 1.85Ghz 3V fan : 1h14m05s 2.00Ghz 3V fan : 1h10m24s 2.00Ghz 3V fan : 1h09m39s gpu_freq=600 sbc-bench http://ix.io/1Ojp Ubuntu arm64 ------------ default clock 3v fan Tinker heatsink : 1h21m05s 1.75Ghz 3v fan : 1h08m42s 2Ghz 3v fan : 1h00m12s sbc-bench http://ix.io/1OqR Temperatures ------------ Big Tinker heatsink no fan idle : 58°C maxed out : 83°C heavy throttle to 1000Mhz after about 3 minutes 3V fan idle : 37°C maxed out : 50°C OC 1.75Ghz 3V fan maxed : 55°C OC 1.85Ghz 3V fan maxed : 57°C Power consumption ----------------- Default idle no wifi : 0.64A Default idle with wifi : 0.7A Default maxed : 1.3A 2Ghz over voltage 4 GPU 600Mhz idle : 0.8A maxed : 1.85A (2A with fan) Transfer speeds --------------- USB3 with SSD : 394MB/s SD-cardreader read : 40MB/s SD-cardreader write : 20MB/s WIfi : 24Mbps Issues ------ Governor again shows falls frequency numbers. vcgencmd measure_clock arm <- show the real ferquency Undervoltage problem is still there. It requires +5.15V or it's undervolting and clocked to 600Mhz OC -- over_voltage=2 arm_freq=1750 over_voltage=4 arm_freq=2000 gpu_freq=600 SoC : Broadcom BCM2711B0 quad-core A72 1.5Ghz (up to 2Ghz) GPU : VideoCore VI @ 500Mhz RAM : LPDDR4-2400 SDRAM HDMI : dual micro HDMI 4K 60Hz + 1080p or 2x 4K 30Hz USB : 2x USB 3.0 / 2x USB 2.0 Ethernet : Gigabit Ethernet |
Nice info Nico !

It'll be great once they sort out the software drivers, but until then, mine is back in it's box.
EDID not working - no USB booting - I need both. |
