Raspberry Pi 4 IS NOW AVAILABLE!

After many years of waiting the Raspberry Pi Foundation has finally released the 4th generation of its super small computer the Raspberry Pi 4 Model B.

Compared to the older versions a lot has changed! The whole hardware on the tiny board has been modernized and beefed-up. Take a look at the list below for some highlights of the brand new Raspberry Pi 4 B.

Raspberry Pi 4 B features:

• 1.5 GHz quad core 64 Bit ARM Cortex-A72 CPU (3x higher performance)
  
• 1 GB, 2 GB or 4 GB of DDR4 RAM
  
• truely dedicated Gigabit Ethernet (full-throughput)
  
• improved dual band WiFi AC networking
  
• Bluetooth 5.0
  
• two USB 3.0 and two USB 2.0 jacks
  
• dual monitor support over mini HDMI (up to 2x 4K resolution)
  
• VideoCore VI powerful GPU
  
• 4k @ 60 FPS HEVC hardware decoding
  
• full compatibility to older Raspberry Pi products
  
• USB-C power jack
  

Pricing starts as always from $35 and up.

The true game changers are finally here (imho):
- Raspberry Pi boards have been suffering from low network speeds but this is history now with the dedicated real Gigabit Ethernet jack.
- I/O has also always been an issue but even that is fixed by finally introducing USB 3.0 jacks.
- Don't have enough RAM? No problem! With the two new 2 GB and 4 GB versions you can get more RAM if necessary. And we're talking about high speed DDR4 RAM.
- The GPU performance has always been rather poor. Not anymore! The new GPU is capable of dual monitor in 4k resolution and 4k @ 60 FPS video encoding. Once again turning this little PC into the perfect machine for media consumption.


What do you think?

I was previously thinking to buy a Raspberry Pi so that I can get deeper into the "techy" things. And it looks like something is in my budget which is quite the latest in technology.

I'm sorry for my bad knowledge about Raspberry Pi. But may I know what components come with them? Like, What actually Raspberry Pi is? Is it just a motherboard? Does it come with a RAM? What are the other components does it comes with?
And how do I get started to make a "computer" out of it? What would I need and how much would my budget go if I already have a monitor?

A Raspberry Pi is a SBC (Single Board Computer) with a SoC CPU (System-on-a-Chip). That means all components such as the CPU (GPU is in the CPU), RAM and many other components such as USB jacks, Ethernet network jack, WiFi card are already soldered on the mainboard but cannot be replaced or upgraded. You don't need to buy RAM or a CPU for it. All you need for a Raspberry Pi is a good SD card (for the OS), a USB keyboard and mouse (wireless also possible), WiFi or a Ethernet cable, a USB-C power supply (for the new one - older use micro USB ) and a monitor with the right cable.

I guess you already have a) keyboard and mouse, b) a monitor and c) WiFi or Ethernet. Now you basically only need a Raspberry Pi starter kit that comes with the Raspberry Pi, a SD card, a power supply for the Raspberry Pi and other cables such as one for the monitor (probably HDMI to micro HDMI or HDMI with a HDMI to micro HDMI adapter). Depending on your monitor you might need a different cable. Let's say you only have VGA and DVI. In that case you need a micro HDMI to DVI cable or a HDMI to DVI cable with a HDMI to micro HDMI adapter. Alternatively the Raspberry Pi has component video so it can be connected to TVs that still have component video jacks.

You can also run the OS from a USB device but you will still need some kind of SD card because the bootloader has to be on the SD card and the Raspberry Pi generally automatically boots from the SD card. There is no BIOS on SoC systems so you cannot change boot behaviour but there are tricks like installing the bootloader on the SD card and the OS on a USB thumb drive or a USB HDD/SSD.

Your budget is a hard question. I don't know how much it would cost in your country. If it would be even available there so soon. Maybe you have to import it from somewhere else. That could include import costs and etc. I don't know the market for computer parts in your country. So hard to say what budget you need. Usually things like the cables are cheap and nowadays good SD cards with a lot of space are also cheap.


If I would buy the 2 GB RAM version from let's say RS Components and Amazon :
- Raspberry Pi 4 Model B 2G SBC for 39,08 € (RS Components)
- OKdo Raspberry Pi Multihead Power Adapter 5.1V / 3A for 9,29 € (RS Components)
- Samsung Evo Plus microSDHC 64 GB for 14,55 € (Amazon)
- Micro HDMI to HDMI cable for 6,45 € (Amazon)
Total: 69,37 € ~ $79

The thing is that usually there are bundles available that include the Raspberry Pi, a case, PSU, SD card and cables for less than if you buy component by component. Of course usually the included SD card might not be that good (slow for example) and the PSU might not be so high quality. These bundles as starter kits are enough though. You can easily buy better SD cards and such later to replace the cheap ones from the bundle.

I am really impressed with this new version since the limitations of the previous version was always the RAM and the video output. Since it can also decode 4k video files on the fly I think if you are a low volume video professional you can get behind it for cheap. Even if you stack it.

Is there any other portable/coc computer that is cheaper and comparably powerful or more ?

There are many other SBC devices with SoC on them in the market. Orange Pi, ODROID, Pine and many others. All have different board versions with more and less features (small ones, big ones, medium ones, ones with x86 CPUs even). The Raspberry Pi needed this upgrade for years because competitors offered real Gigabit Ethernet, USB 3.0 and some of the other features since long ago already. The price was about the same as the Raspberry Pi.

I only have a few Raspberry Pi of different generations and a 1st generation LattePanda. So I can't really tell you much more. Can recommend the following Youtube channels for fun with SBCs.

Everyone's really excited about this release, I personally have heard about it due to Minecraft being on Raspberry Pi, perhaps Its time for Mojang to upgrade Minecraft for Raspberry Pi as well.

Sorry i also don't have knowledge about Raspberry but know i have little bit knowledge about it. Thanks in the picture i can see there is HDMI port but we can convert DVI cable to HDMI port? with any converter is it safe?

In Pakistan i don't know if it available or not but mostly in local site the Raspberry Pi 3 appeared in 35-50$

Both signals are digital. Only the connector is different. There are already HDMI to DVI cables available and they work. The Raspberry Pi 4 has micro HDMI, so you would need either a) micro HDMI to DVI cable, b) HDMI to DVI with micro HDMI adapter or c) a short micro HDMI to DVI adapter.

Example products:
a) https://www.amazon.com/SIENOC-2x1-8m-Gol...B07D2YSWP8
b) https://www.amazon.com/Cable-Matters-Mic...B00JDRHQ58 (micro HDMI to HDMI adapter) and https://www.amazon.com/AmazonBasics-Inpu...B014I8UQJY (HDMI to DVI cable)
c) https://www.amazon.com/Tripp-Lite-Micro-...00HLDF29I/

If you monitor has HDMI then you simply need a micro HDMI to HDMI cable or adapter with a normal HDMI cable.

You could even get a converter from HDMI to VGA if you only have VGA but I have had bad experience with that because VGA is a old analog signal. So those converters may not work good and may not always work with all devices.

4K Support
A72 core instead of A53
Better GPU
MORE RAM (expensive model)
its all great and with the same $35 price

The main criticism for raspnerry pi for sometime is how the raspberry pi isnt powerfull but with this new iteration that claim 3x faster speed than raspberry pi 3 hopefully this get solved

But compared to mainstream desktop processor or even laptop processor it is still not that powerfull but they said enough for light desktop use which is what raspbery pi is suffering from . A72 core is not new the newer one is a76 cmiiw but it is ,uh better than a53 and the
