Hey folks, Rob here from the Magpie, the official Rosy Pie magazine. Now today I'm here at the Rosy Pie store in the Grand Arcade in Cambridge for a very special occasion. The launch of the brand spanking new Rosy Pie 4. Welcome to the new generation of Rosy Pie. I'm really excited to finally show you all the Pie 4. It's been a development for quite a while now. And every time I was up in the office I got to hear about some of the amazing things that were happening with it during development. Here it is though, the Rosy Pie 4 model B. The new system on a chip is not just an improved 2835 like the last few, but a brand new SLC built specifically for the Pie 4. Now this new generation of chips is the BCM 2711, and includes a 64-bit quad core, Cortex 872 processor that clocks at 1.5GHz, and includes up to a whopping 4GB of RAM up from the 1GB on the last few flagship models. That alone is a massive jump in power, and I benchmarked show that it's a staggering 4x faster than the 3B Plus. It also has an upgraded graphics processor. Gone is the Velucor 4 of every single Parth Rosy Pie, replaced with the brand new Velucor 6. Now this bumps the Pie 4's video outputs to 4K, which can now be done via 2 HDMI ports. You can see here that 2 mini HDMI, and there may be mini HDMI, so both of them can fit in the board. The other ports have also been upgraded. There's now the Gigabit Ethernet. Two of the USB ports are 3.0, and the Bluetooth is being upgraded to 5.0, and the wireless LAN is even more powerful. With all these extra amazing features, the Powerport has also been upgraded to a 5V 3A USB-C port. It's truly a beast, but you don't have to take my word for it, although why wouldn't you? I'm very trustworthy. As we have a load of benchmarks to back this up. Hello, I'm here with James Adams, the technical leader at Rosy Pie trading, and we're going to talk about some of the amazing benchmarks that the Pie 4 has done for us. We'll be showing them on the screens, we've discussed them, but the main takeaway from these benchmarks is that the Pie 4 is faster, it's better, it's stronger, it's more pie, it's great. Pie is one of the pie for your money. It's a faster processor, it's full Gigabit Ethernet, it's USB3, it's two display outputs, it's more RAM, and it's a Rosy Pie. It looks very much like an old Rosy Pie. Yeah, and you're aiming it, one of the good things about it is that like a desktop, it's like a real desktop, it's like a full desktop PC. Yeah, so it really works very well as a sort of comparable to a low-end X86 kind of desktop PC, with the upgrades to the IO performance and the CPU performance, you can, and the memory, running things like Chrome, web browsing, running Gmail, Facebook, these kind of things all work fairly nicely on the pie now. YouTube, YouTube runs fine. So yeah, it's really got a great kind of PC feel now. For some of these benchmarks, let's start with the big one, the CPU test. We're using an impact for this test. Our figures for the 3B Plus is about, what does it say here, 225 million instructions per second, and our results for the Pie 4 are about 941 million instructions per second, which is just a four times faster in these tests. Yeah, okay. So, okay, so Lim-Pack is a fairly synthetic benchmark. The CPU on the new machine is, it's more advanced, more advanced core. It's running at 1.5 gigahertz versus 1.4 on the Pie 3D Plus, and it doesn't sound like a lot, but the thing is the core is much more advanced, so it does out of order execution, so it can actually execute per clock many more instructions. So, I mean, Lim-Pack, that's a nice number. We see in real world, in real world sort of, you know, say browsing, it's about two and a half to three times faster, across the board. We're just... It's only quite a bit impressive. Yeah. And you couple that with more memory that you can have on the higher tiers of product. You know, it's a great PC. Yeah, speaking of memory, the bandwidth has also increased in the front. I think our figures are showing like, you know, a 50% at least increase in bandwidth there. Yeah, so the memory is now up in the DR4, so that's the same kind of memory that you have in your mobile phone. Yep. And it's running at 2.4 gigahertz. It has the option to boost up to 3.2 gigahertz as well, for it's doing 4Kp60. Oh. Yeah, so it's a... It's a... A doubling of memory bandwidth, which is fantastic. Speaking of 4Kp60, one of the cool things about the Pi4 is that, for the first time we're getting an upgrade to the video core from VC4 to VC6, which is the GPU part of the Pi4. You know, how good is this new video core then? So it's an evolution of the video core for 3D engine inside the original Pi3 and 2 and 1. It's running a little bit faster in terms of clock rate, but it's got more silicon under the hood, basically. It'll do OpenGL ES3, for instance, of your ELST EL, OpenGL ES2. So there's sort of a tick box update, but yeah, as you can see, it's about two times sort of raw performance increase over the previous generation. Which is great. And even with all this extra power draw, or all this extra power from the Pi, we've got some figures on the power draw here. And it's only like a small increase when we're going idle, even with a bit of power draw as well. How has that been achieved, even with such a big power increase? Sure. Good question. So the new processor on this board is BCM2711. It's a new 28-animate processor from Brookham. The previous boards, Eben said at the Pi3B Plus launch, this is the last board that uses the older 40-animate technology. So we've moved down a silicon technology node. That gets you more transistors in the same area, faster transistors and lower power transistors. So we've been able to put these faster CPU calls on. And also, just pay attention to the power on all parts of the board. So we turn the clock down when there's not much going on. And we sort of deep-power things where we can. So we've managed to achieve quite a good, similar power consumption to the 3B Plus. It will be a reasonable amount more when you're actually running flat out. But not very much. Great. I mean, obviously everything else is slightly faster. So it used to be 3.0, which is going to be a new huge increase in about 10 times faster than 2.0. So yeah, about 10 times faster. If you put a fast SSD in your USB-3 and do a retest, you'll get sort of north of 350 megabytes a second. Well, and even the SD card is faster than before in the 3D Plus. Indeed. Yep. So we've doubled the speed of the SD card as well. So that will help people. But if you really want to blazing faster, disk performance, it's probably a good idea to use an SSD. Great. Well, thank you so much for trying to me about the Pi4. And I hope everyone's got a bit more better idea of how what we've done to make this better faster. So yeah. Great. Thanks, Rob. Thank you.
