What\u2019s new with the Raspberry Pi 3 Model B+?<\/h3>\n\n- Faster network<\/strong>
\nThanks to the new LAN7515 chip, Gigabit Ethernet is finally supported. However, you cannot expect the full gigabit data rate. The reason for this is that the chip hangs internally on a USB 2.0 controller, so 315 Mbit\/s is the end. In its predecessor, the Raspberry Pi 3B, the speed was only 95 Mbps. Thus one can be completely content with the increase.<\/li>\n- Higher CPU clock<\/strong>
\nThe four ARM cores have also been improved. These now clock at 1.4 GHz instead of 1.2 GHz and are therefore around 17% faster. A sheet metal lid serves as a heat spreader to better dissipate the waste heat associated with the increased clock frequency. However, the higher clock speed also results in higher power consumption.<\/li>\n- 5 GHz WLAN ac<\/strong>
\nThe Broadcom BCM43455 is a new WLAN controller. This now supports dual-band ac WLAN for the 5 GHz frequency band. Instead of two, however, only one antenna is installed, so that the throughput increases only moderately.<\/li>\n- Power-over-Ethernet (prepared)<\/strong>
\nThe Raspberry Pi 3B+ now has 4 pins for PoE on the board. A PoE HAT<\/a> for the Raspberry Pi, which can supply the Raspi with up to 12.95 watts (IEEE 802.af), will be available soon.<\/li>\n<\/ul>\n
\n <\/p>\n
First measurements<\/h3>\n
Meanwhile I could measure the new Raspberry Pi 3B+ and the power consumption turns out fortunately less dramatically, than first assumed.<\/p>\n
Test setup<\/h5>\n\n- Raspberry Pi 3B+ \/ 3B without case<\/li>\n
- Network via cable to GBit switch<\/li>\n
- OS: Raspbian Stretch Lite (Image 2018-03-13)<\/li>\n
- Two measurements: Idle<\/em> and under load
(“sysbench –test=cpu –cpu-max-prime=20000 –num-threads=8 run<\/em>“)<\/li>\n- Room temperature: approx. 22\u00b0C<\/li>\n<\/ul>\n
Test results<\/h5>\n

The RPi 3B+ has a significantly higher power consumption (approx. +80%) than its predecessor. At full load, it is still approx. 45% higher than that of the RPi 3B. However, thanks to the new heatspreader, the RPi 3 B+ is around 10\u00b0C cooler than its predecessor. Since the Raspberry Pi automatically reduces the clock rate from a temperature of 85\u00b0C, the lower temperature of the RPi 3B+ is a real advantage. This means that the extra power can really be called up without it getting into throttling.<\/p>\n
\n <\/p>\n
Is it worth replacing the Raspberry Pi 3B with the 3B+?<\/h3>\n
Maybe. That depends on what the Raspberry Pi is used for. If the focus is on CPU performance, such as in a media center, the new 3B+ will of course do better justice to the task. The same applies to high network throughputs. If, on the other hand, an energy-saving, cool system is required, then there is no reason to change. The price of the new RPi 3B+ and its predecessor is identical.<\/p>\n
