What makes the Raspberry Pi special is the GPIO and the many opportunities it affords us.
Without the GPIO (see Raspberry Pi GPIO pinout), the Raspberry Pi is just a small Linux computer.
The automatic overclock built into Bullseye takes the Pi 4 to 1.8 GHz, the same speed as the Raspberry Pi 400 and the reason for that is that the newer Pi 4 shares the same SoC as the Pi 400. All of our Raspberry Pi 4 are from the early batches so we cannot comment on the automatic speed boost, but we have performed extensive overclocking experiments with the Pi 4 and found that with, adequate cooling, it’s easy to overclock the Raspberry Pi to 2.14 GHz. On the bright side, Bullseye comes with an added speed boost for newer Pi 4 models. The difference between the two is so small that’s probably within the margin of error and not noticeable. To find out how Bullseye runs applications, we opened a fresh Chromium browser to a blank tab, and Bullseye completed the task in 7.92 seconds while Buster handled it in 7.74 seconds. Bullseye drags behind at 28.48 seconds, a delay that we can really feel. has seen many updates and tweaks to the boot process. For now Buster is the clear winner, clocking in at 21.84 seconds, which makes sense since the older OS. On our test Raspberry Pi 4 with 4GB of RAM, we booted Bullseye and Buster and timed from the appearance of the rainbow image to a usable desktop. Performance of Raspberry Pi OS Bullseye vs Buster We ran Chromium via the terminal, as any errors would be output and saw reference to an “ service” which we assume is automatically part of Bullseye. General browsing on Chromium 92 in Buster worked well, as and bbc.co.uk both loaded and rendered flawlessly. However, in my testing, YouTube crashed every time we loaded a URL so that’s a bad sign.
CHROME OS WOLFRAM PLAYER INSTALL
Theoretically, you could get the benefits of Chromium 92 on Buster as the new browser will install in the old OS. YouTube showed some frame drops in its “Stats for Nerds,” menu option but we didn’t notice any disruptions with our naked eyes.
CHROME OS WOLFRAM PLAYER 1080P
However, 1080p 30 playback was very good. It wasn’t a total slideshow, but was bordering on unwatchable. When we played the Big Buck Bunny test video, we saw that 1080p 60 playback was still poor.
CHROME OS WOLFRAM PLAYER 720P
With Chromium 92, we find that 720p video, windowed and full screen, plays back exceptionally well, with just 1 percent of frames dropping. With older Raspberry Pi OS releases anything above 720p is a slideshow, and full-screen 720p is also not an enjoyable experience. Version 92 of Chromium takes advantage of the Raspberry Pi hardware acceleration to really speed up streaming video. Bullseye also brings an update to the Chromium browser.
