I have a Raspberry Pi 4 Model B in front of me and have just run some benchmarks using the Phoronix Test Suite.
TL;DR: Prime CPU test; Pi4B: 60 seconds, Pi3B+, 80 seconds, Render test: Pi4B 27fps at 720p, Pi3B+ 16fps at 720p.

- vardump 7y agoPlease run SD card benchmarks, assuming you have a fast card available.
- Tepix 7y agoSeems to be UHS-I because it isn't mentioned anywhere.
- bscphil 7y agoHi, thanks for running this. It's helpful information. Something strange is that in your cpuinfo the SoC is detected as BCM2835, while in all the spec sheets online it's supposed to be BCM2711. Do you know if you are possibly working with a different version of the hardware? One reason this is important is that some of us in this thread are trying to work out what the video decoding and 4K HDMI capabilities are with this new hardware. In particular, the specs say the BCM2711 is supposed to be a VideoCore VI SoC, but your dmesg is showing that the vc4 driver blob is being used. If you could add any information that would help that would be awesome!
- monocasa 7y agoBCM2835 vs BCM2711 is all in software, the board itself doesn't tell you explicitly. The regular vc4 drivers are just an rpc to the code running on the GPU with start.elf. I wouldn't be surprised if the old drivers just worked.
- bscphil 7y agoThat's probably the right explanation. Thanks!
- marcani 7y agoHow hot does it get when in idle and how hot after about 10 min full cpu load? What are the prospects on overclocking?
