What new features brings the Raspberry Pi 4B?<\/h3>\n\n- Faster network<\/strong>
\nNow “real” Gigabit Ethernet is finally supported. Although the predecessor was also advertised with Gigabit-Ethernet, real was finished at about 300 MBit\/s. The reason for this was that the chip was internally attached to a USB 2.0 controller. With RPi4 this is now a thing of the past and the performance of the Gigabit Ethernet interface has tripled.<\/li>\n- Higher CPU clock<\/strong>
\nThe four ARM cores were also improved. These now clock with 1.5 GHz instead of 1.4 GHz. The latest version of the Raspberry Pi 4 uses a Broadcom BCM2711 chipset. Compared to the predecessor model, the performance of the chip is said to have tripled.<\/li>\n- Memory \/ RAM<\/strong>
\nThere has been a big leap in RAM performance. Where previously only 1GB was available, the RPi4 is now available in three different RAM versions (1GB, 2GB, 4GB). In contrast to the Raspberry Pi 3B+, which still relies on LPDDR2 SDRAM, the Raspberry Pi 4 has much faster LPDDR4 SDRAM installed.<\/li>\n- connections<\/strong>
\nProbably the most striking new feature is the two micro HDMI ports, which are available for video and sound (support for up to 4kp60 or dual dual 4kp30). In addition, real Gbit Ethernet and USB 3.0 with two ports is finally on board. Last but not least, the RPI4 is no longer powered by Micro-USB, but by a USB-C port. So you need a new power supply, or at least an appropriate adapter.<\/li>\n- Case<\/strong>
\nAs mentioned above, the connections and positions of the ports have changed on the Raspberry Pi 4. Therefore the previous housings (2B – 3B+) can no longer be used with the new RPi4.<\/li>\n<\/ul>\n
\nMy conclusion<\/h5>\n
The Raspberry 4 is an impressive upgrade and contains long awaited hardware improvements that many, including me, have been waiting for. But not everyone will like the changes that come with it, because inevitably new accessories (case, power supply, HDMI cable\/adapter) will be required due to the changed connections.<\/p>\n
Another dark side can be the power consumption, depending on the application. Because more power and faster connections are of course also more power-hungry. In comparison to the predecessors, the power consumption, especially idle, has increased significantly as a result. If the focus is on performance or high network throughput, such as in a media center or small server, the new Raspberry Pi 4B will clearly be the best choice. If, on the other hand, a power-saving system is required, then it is worth taking a look at the previous models. Especially the Raspberry Pi 3B (not 3B+), with max. 4.4 watts under load instead of 7.6 watts for the RPi4, may be the better choice for small, power-saving control tasks.<\/p>\n
