**The New Raspberry Pi 4: A Powerful Upgrade**

I recently had the opportunity to try out the new Raspberry Pi 4, and I must say, it's a significant upgrade from its predecessor. The Pi 3 B+ was already a great little single-board computer, but the Raspberry Pi 4 takes things to the next level.

**4K Video Playback in VLC**

I decided to test the Pi 4 with 4K video playback using VLC. I tried playing a 4K MP4 file at 30fps and saw that it was maxing out the CPU. This is not ideal, as we want the GPU to handle video acceleration. In Kodi, which uses an older Krypton version of the operating system, I was also able to play the 4K MP4 file, but it didn't perform much better.

**Raspberry Pi 4 Performance**

I ran some benchmarks using SiS Bench and Linpack SP to compare the performance of the Raspberry Pi 4 to its predecessor. The results were impressive: the Pi 4 outperformed the Pi 3 B+ by a significant margin. This is thanks in part to the new Cortex-A72 CPU, which offers much higher performance than the older Cortex-A53. Additionally, the Pi 4's LPDDR4 20 GB/s SDRAM offers much higher throughput than the old DDR2 RAM.

**Gigabit Ethernet and Upgraded Video Core**

One of my favorite features of the Raspberry Pi 4 is the upgraded video core six GPU. On average, I was able to get 39.7 FPS with the stock clock speed, which is a significant improvement over the Pi 3 B+'s 28.4 FPS. This makes me confident that we'll see improved performance in future software updates.

**Emulation Performance**

I also tested some emulation performance on the Raspberry Pi 4. I tried running PlayStation 1 games using RetroArch and was able to get around half speed due to the lack of complete compatibility with the new CPU. The GPU acceleration still hasn't been fully optimized, which is a major limitation for emulation.

**Benchmarks**

I ran some benchmarks to compare the performance of the Raspberry Pi 4 to its predecessor. Here are the results:

* SiS Bench:

+ Pi/4: 389

+ Pi/3 B+: 258

* Linpack SP:

+ Pi/4: 389

+ Pi/3 B+: 258

These results show a significant gain in performance over the older Raspberry Pi 3 B+. This is due to the new Cortex-A72 CPU and LPDDR4 RAM.

**Gigabit Ethernet**

I also tested the Gigabit Ethernet connection on the Raspberry Pi 4. Unfortunately, my internet connection was only 450 Mbps, which meant that I couldn't fully utilize the connection. However, this highlights an important point: we need to find ways to optimize the software for full-speed performance.

**Overclocking and Full-Speed Performance**

One of the most exciting things about the Raspberry Pi 4 is its potential for overclocking. With a video core six GPU that can be overclocked, I'm confident that we'll see significant improvements in future updates. In fact, I've already successfully overclocked the CPU to 620 MHz and 1.7 GHz.

**Conclusion**

The new Raspberry Pi 4 is an incredible upgrade over its predecessor. With improved performance, Gigabit Ethernet, and a powerful video core six GPU, this single-board computer has a lot of potential for gaming, emulation, and other applications. However, it's still early days, and we'll need to wait for software updates and developer support to unlock the full potential of the Pi 4.

**Software Developments**

I'm excited to see what developers will create with the Raspberry Pi 4. I've already mentioned the possibility of full-speed emulation on platforms like Retropie, which would be a major milestone for the community. With the Pi 4's powerful CPU and GPU, we can expect to see significant improvements in performance over time.

**Conclusion**

In conclusion, the new Raspberry Pi 4 is an impressive upgrade that promises to deliver improved performance and capabilities. While it may take some time to fully realize its potential, I'm excited to see what the community comes up with.

"WEBVTTKind: captionsLanguage: enwhat's going on guys it's the CTA Brighton back here again today I am super excited because I finally got my hands on the Raspberry Pi 4 and I want to do some testing on it so this is gonna be my first look initial impressions and I will have more videos on the way so in this video I'm going to be testing out the Raspberry Pi for 2 gigabyte model I actually have a 4 gigabyte model on the way it should be here in the next day or two and I have cross-referenced all the benchmarks that have run on the 2 gigabyte model with some that are online for the 4 they are pretty much exactly the same personally I'd rather have the 4 gigabyte model but it doesn't mean that it's going to be faster than the 1 or the 2 gigabyte model it just has more RAM it doesn't mean it's a more powerful unit you will be able to multitask a lot better with more RAM and if you're interested in picking up a Raspberry Pi 4 and you can only find the to kick a bite model it's still a great choice over the one so here it is a lot has changed in the Raspberry Pi 4 compared to the older models like the Raspberry Pi 3 or the 3 B+ performance is also significantly increased over previous models of the Raspberry Pi we now have a better CPU faster RAM and a newer video course / GPU unit inside of here the overall size of the Raspberry Pi 4 has stayed the same but they've changed the layout so this means we cannot use older cases for the Raspberry Pi 3 or the three B+ if we take a look on the left-hand side we have a Raspberry Pi 3 B+ on the right is the PI 4 the Ethernet port has been totally relocated microUSB has been replaced with USB type-c and a single full size HDMI has been replaced with 2 micro HDMI outputs so now it's just a matter of waiting for the case manufacturers to get a hold of their samples so they can go ahead and create new cases for this by the way Fleur does have one in the works and there's a pre-order ready on their website I'll leave a link in the description I'll have a full video on one as soon as I can get it in my possession so let's take a look at the specs and then we'll get into some testing on the Raspberry Pi 4 for the CPU we have the new broadcom BCM 27 11 this is a quad-core cortex a7 t2 at 1.5 gigahertz the Raspberry Pi 3 B+ used a cortex a53 at 1.4 and this might not sound like a big game just going 100 megahertz up but these a seventy two cores offer much higher performance than the a fifty threes so clock for clock this is a better CPU I've had a lot of people get upset with me when I call the video court GPU but basically that's what we have this is our graphics processing unit or video processing unit it's using the new video course six at 400 megahertz and by the way I have successfully overclocked the GPU to 620 megahertz and the CPU 21.7 I will have a full tutorial coming up very shortly as for RAM there's three variants of the PI for one gigabyte two gigabyte or four gigabyte they all use lpddr4 2400 SDRAM and this is a huge upgrade over the old Raspberry Pi fours and personally this was the biggest surprise not the amount of RAM I figured they would at least go to two fours awesome but going from ddr2 to ddr4 and a little single board computer like this is a big upgrade and this is gonna help us out dramatically in everything we do on the PI they've added true Gigabit Ethernet dual band 802 dot 11 B G and an AC so it can pick up that 5 gigahertz Network Bluetooth 5.0 2 USB 3.0 ports two USB 2.0 ports Raspberry Pi standard 40 pin GPIO header USB type-c for power they've done away with the micro USB but this does require more power to run 5 volts 3 amps and finally 2 micro HDMI ports they claim 4k 30fps if you're using dual monitors or 4k 60fps if you're using a single the PI 4 has been out for about 4 days as I'm making this video and I've tested some 4k playback doesn't work great yet but it's still really early for the software and the hardware running the raspbian desktop in 4k works well but trying to stream or playback native 4k content it really struggles but all of this will improve over time as more developers get it in their hands like I said it's only been 4 days since it's been released as making this video so now it's time to get into some testing I'm gonna be running raspy and Buster you can download it from the official Raspberry Pi website flash it to your SD card and you'll be up and running in no time all right so here we are with raspy and Buster on the Raspberry Pi for like I mentioned I'm using the 2 gigabyte model we're gonna get the same performance as the for right now we're only using 131 megabytes of memory out of that 2 gigs so the first thing I want to do is head over to YouTube and check out some video streaming from the platform now in the past on the Raspberry Pi 3 or the three B+ we've kind of struggled with video streaming from YouTube hopefully it's fixed here but uh it's still really early and we're not gonna be checking this out in 4k because this is only on a 1080p display I do want to make sure we are set at 1080p 1080p 60fps and I'll check out stats for nerds so it definitely looks like it's struggling with the 1080p 60fps I'm just gonna go up a little bit more and one of the main things is whenever we put this in the full screen on the Raspberry Pi 3 or 3 B+ really really struggle so we're gonna test that out if it'll go into full-screen mode and my internet is plenty to buffer this out looks like we're struggling at 1080p let's take it down to 720 so that 720 fullscreen let's go back down it's gonna work a lot better when it's not in full-screen mode looks pretty good there I do like watching my videos in full screen though so we're gonna go down just a little bit more let's take this to 360 should work great in window mode nice and smooth let's go to fullscreen so even at 360p full-screen mode it still looks like a struggle in a little bit but like I mentioned this is really early and this is only gonna get better over time but overall if you want to use a Raspberry Pi for to check your email and go to web pages it does perform much better than the PI 3 bit now another thing that everybody's been excited about here is video playback again performance is not great right now so this is the built-in VLC media player I do have a couple files that I wanted to test first up we have a 60fps mp4 this is Big Buck Bunny still choppy now I did try 4k in VLC I was also able to install Kodi this is the older Krypton version and let's see if that 4k I was talking about works in here I don't think it's gonna play it at full speed this is a big bug bunny 4k 30fps mp4 and we are maxing out that CPU so inside a Kodi we don't have any GPU acceleration right now we're maxing out all four cores with this 30fps mp4 so starting out Raspberry Pi 4 definitely needs some work with video acceleration by the way there is a Libra elect build out there and it should perform a little better than this but it's still really really early as making this video the Raspberry Pi 4 was released four days ago I was also able to install retroarch but since the software's not completely ready we're getting around half speed on PlayStation 1 emulation this will definitely work at full speed when everything's ready to go but it's gonna take a little bit of time to get all of these drivers in order I also tested Sega Saturn using the yo bossy core and it runs out about 15 fps so like I mentioned I did run a bunch of benchmarks first up we have sis bench now with all of these that you're about to see higher equals better pi/4 at the top 389 pi/3 b + 258 now this is straight cpu performance we're getting a significant gain over the old PI 3 B+ same thing with linpack SP even though the Raspberry Pi 4 is only overclocked from the Raspberry Pi 3 B+ by 100 megahertz it's using a new cortex a 72 CPU instead of the old a 53 and these a seventy two cores offer much higher performance over the a 53 s even if they were clocked at the same exact speed another big jump for the Raspberry Pi 4 is the use of lpddr4 20 400 megahertz SDRAM instead of the old ddr2 in the Raspberry Pi 3 or the 3 B plus this Ram offers much higher throughput be it reading or writing from it we also get true Gigabit Ethernet on the Raspberry Pi for unfortunately my connection is only 450 megabits per second and it totally destroyed that everything it could from it as opposed to the Raspberry Pi 3 B+ where I could only get 232 upload speed is exactly the same for each I'm only at 25 megabits per second but both Macs that out and finally one of my favorite things about the new Raspberry Pi 4 is the upgraded video core six GPU on average with the Raspberry Pi 4 I was able to get thirty nine point seven FPS and the PI 3 B+ twenty eight point four so we have a good gain there and keep in mind that all of these are at the stock clocks this video core 6 can be overclocked I've successfully done 620 megahertz and one point seven on the CPU I will have a full overclocking guide coming out soon so definitely keep an eye on the channel a nice upgrade over the Raspberry Pi 3 B+ it's still really early for the software and hardware as soon as more developers get their hands on this performance will increase in all aspects of this board one of my main things I do on this channel is emulation especially on the Raspberry Pi 3 this is gonna be an awesome little upgrade I do believe we're gonna get full speed in 64 emulation eventually better Dreamcast emulation better PSP emulation but this board will never do GameCube or ps2 I also have a feeling that it's gonna struggle with Sega Saturn emulation you got to keep in mind that this is still a 35 45 or 55 dollar single board computer depending on how much RAM you get with it and is still using a low-end arm CPU you can actually buy prepaid phones for around 45 to 55 dollars that will outperform the Raspberry Pi and straight CPU and GPU performance but that doesn't make the Raspberry Pi for any less awesome this is and will be a great little single board computer we just need to get more of them in the hands of awesome developers out there the PI community is great and I can't wait to see what they do with the Raspberry Pi 4 so that's pretty much it for this video guys I really appreciate you watching if you have any questions let me know in the comments below and I will have a ton of videos coming up on the Raspberry Pi 4 we just need to give it a little bit of time I know everybody's super excited including myself about seeing retropie running on this and it will eventually it'd be really cool if you could hit that like button maybe subscribe to the channel but like always thanks
