Raspberry Pi 3 B+ Vs 3b Benchmark
Raspberry Pi Model 3 B+
The 3B+ does have a slightly faster revision of the Broadcom processor, but the existent improvements are on the networking side. If you're buying new, definitely spend the actress few dollars; but nosotros wouldn't rip out any model 3B board that is nonetheless working fine.
Raspberry Pi Model 3 B
The original Raspberry Pi 3B is all the same very capable. The Plus upgrade consists of a new spec for the processor that doesn't actually offering whatever advantage and some networking hardware changes — namely Gigabit Ethernet, PoE, and a new Dual-band 802.11ac Wi-Fi fleck.
Nosotros saw an all-new model Raspberry Pi in 2019 with the Raspberry Pi 4 (opens in new tab), but the iii B and iii B+ are still very capable. In the smartphone earth that + means you should expect something bigger, but in this case, the differences are a bit more than nuanced. Let's take a peek at what's new for the three B+ and encounter why you should wait for i to build your next project instead of only grabbing a tried and trusted Raspberry Pi three and start wiring things.
Raspberry Pi 3B vs. 3 B+
Tiny corrective changes aside, there are two important differences between the 3 and the 3 B+: a new network interface and a slight processor revision. These changes aren't enough to rip out your Pi from whatsoever existing projects, only they could matter for whatever you take planned adjacent. Especially if you lot're building your own Net of Things (IoT) device like a remote sensor or camera controller.
| Model 3B | Model 3B+ | |
|---|---|---|
| Processor | Broadcom BCM2837 SoC @ ane.2Ghz | Broadcom BCM2837 SoC @ ane.4GHz |
| Ethernet | 100Base | 1000Base |
| Wi-Fi | 802.11b/1000/due north | Dual-Ring 802.11ac |
| PoE | No | Yes |
| RAM | 1GB LPDDR2 | 1GB LPDDR2 |
| Ports | DSI x1, RCA x1, HDMI x1. USB x4 | DSI x1, RCA x1, HDMI x1, USB x4 |
The specs tell the story hither. The processor upgrade isn't enough to warrant a new part number, but the SoC package itself has visibly changed then you might need a new heatsink of your project calls for 1. The revision (marked as a020d3 if y'all happen to accept access to the Broadcom specifications) brings i affair to the Broadcom BCM2837 SoC — it's now clocked at a maximum of 1.4GHz instead of 1.2GHz.
A 200 MHZ bound usually brings a significant performance increase. In early tests based on a beta release of the Os, pure data-driven benchmarks like verifying prime numbers prove a performance boost of 15%. Unfortunately, the CPU is rarely the bottleneck on a small unmarried-lath figurer and without changes like a new storage interface adapter or a bump in the SoC cache, you probably won't see much existent-world benefit.
Practice I demand a model three B+?
The large draw though, and why you might want to consider sourcing a Raspberry Pi B 3+, is PoE. In example you aren't familiar, PoE allows you to ability a device over its Ethernet connection. It'southward a boon to DIY'ers and Makers because it ways you only need to run a single wire for networking and ability, so you lot can control the power programmatically without wiring in any sort of switch or relay.
You probably don't need the 3 B+, merely y'all should buy it anyway.
With a standard model iii B, y'all would have to utilise an enclosure big enough to conform a special splitter or utilise an enclosure that has PoE integrated. That's an increase in cost and takes abroad a flake of the usability a small-scale single-board figurer has due to its size. If you're planning on building any sort of remote smart IoT box you're meliorate served to buy a 3 B+. If you lot don't use PoE now, you still take the option in the future without any changes to the board.
The changes to the network interfaces also mean a 3B+ is the right board if you're building your own NAS or media streaming box using a Raspberry Pi. Clients can take advantage of the faster and wider Wi-Fi connection, and the new NIC supports 9KB "Jumbo" frames in add-on to a 1000Base-TX network. Colossal frames allow for more than than the standard 1500 bytes of Ethernet payload per packet, and in this case payloads up to (theoretically) 9 KB (9000 bytes) are supported. These changes hateful that any streaming box driven by a Raspberry Pi three B+ can send and receive information faster over an Ethernet connexion.
The best affair virtually the changes betwixt the two is that all accessories, like enclosures or HATs, congenital for the model iii B will also fit the model 3 B+. Even if your project doesn't require a new NIC or PoE, that means you could buy a three B+ anyway in instance you want to use information technology for something else in the hereafter. And that'due south what I would recommend. You can selection upwardly a kit that includes the board, a power supply with its own noise filter, a clear enclosure, and ii aluminum heatsinks for about $l from Amazon (opens in new tab). These prices are just a dollar or two more than than the model 3B, and then it's a no-brainer unless you lot have a specific need for the wireless and network chips used on the older model.
The Plus update
Raspberry Pi iii B+
A great refresh
The 3B+ brings improvements where it counts if you're edifice any sort of continued project. Even with its substantial price crash-land, we recommend it over the older model unless y'all have a specific need.
Still doing its affair
Raspberry Pi 3 B
The workhorse
Even if you don't need Gigabit Ethernet or PoE, we recommend the newer 3B+. that all goes out the window if your projection needs the specific networking hardware on the original 3B. If that's the instance, you'll not see whatsoever pregnant difference in operation.
