The people at the Raspberry Pi Foundation heard user feedback and now provide 3 options for the total amount of memory soldered on the board, and they priced accordingly. 1GB: 35 thats the base version to keep the price tag low, and it still makes sense for a lot of applications 2GB: 45 the mid-range version, making it a better option for multimedia applications or a smoother desktop experience 4GB: 55 the top-notch model, with an amount of RAM that removes any limit no matter what you do with your Raspberry Pi 4 The memory split that used to be the basic resource configuration for the GPU is not (almost) gone. Read on for the most detailed Raspberry Pi 4 review ever Wait, is this real Well, yes Last February, Raspberry Pi founder Eben Upton said to Toms Hardware that the Raspberry Pi 4 was not due until 2020. They probably just wanted to make a huge surprise out of this one. The base version of the Raspberry Pi 4 is still priced at 35 Base price you say. Read on note titleImportant:We will be updating this post throughout the next days, so make sure you come back for all the new stuff.note Get a RPi 4 for FREE RPi4 vs RPi3 Specifications For those that need the details, here is a quick comparison chart based on the specs of the Raspberry Pi 4 and its predecessor the Raspberry Pi 3 B. The Raspberry Pi 4 has support (at least, the hardware does) for driving two screens at the same time through HDMI. These can be used either in a mirror configuration, or in an extended desktop type of screen setup. We did manage to get the extended desktop working using a 4K and a 1080p screen. That said, to configure the resolution, a new tool was introduced called Screen Configuration (found under Preferences), which uses the XRANDR API. The downside The two display ports are actually micro-HDMI, which means that you need a micro-HDMI-to-HDMI adapter or cable. Given that the 2 ports are really close together and there isnt much room, you cant use two adapters for dual screen setups and you should instead go for cables. K Resolution and 4K Video Decoding That was the most expected feature of all, at least for us here at Yodeck. Rpi Mpeg Full 4K SupportAll other SBCs on the market boast full 4K support, so we kinda expected that. Rpi Mpeg Code Up ToThe Raspberry Pi 4 can decode up to 4K video at 60FPS, encoded in H.265. Unfortunately, H.264 decoding is only supported for up to 1080p at 60FPS. There is a chance that it can decode two 1080p60 H.264 streams at the same time, but we have not tested it yet. Both codecs are supported out of the box, so no extra licenses are required. However, omxplayer will only play h264 video, while HEVC (H265) is accessed through a different API than OpenMax IL (namely FFmpeg), which will require modifications on many tools dealing with video on the Pi. The VC1 and MPEG-2 codecs that used to require a license in the previous Pi, are gone altogether. The Raspberry Pi 4 supports 4K resolutions (38402160) at several refresh rates, up to 60Hz. Screen resolution combinations How about combinations of these on the two screens Here is what the current status is: When using both HDMI ports, theoretically, you can drive the two 4K screens at 30Hz but firmware support for this setup is not here yet. ![]() You can mix in 4K60Hz and 1080p60Hz on the two HDMI ports. You can use one HDMI port and the DSI port (or the DPI setup for VGA). And you can still use the composite analog video output (available still on the mini-jack port), but you cannot use any other screen port (HDMIDSIDPI) at the same time with composite. We heard unconfirmed rumors that, in the future, there is a remote chance that 3 concurrent digital video outputs might be supported. So, you would be able to use both HDMI ports along with DSI, for a 3-screen configuration. More Memory (Options) One of the biggest restrictions on the previous version was the amount of memory. The people at the Raspberry Pi Foundation heard user feedback and now provide 3 options for the total amount of memory soldered on the board, and they priced accordingly. GB: 35 thats the base version to keep the price tag low, and it still makes sense for a lot of applications 2GB: 45 the mid-range version, making it a better option for multimedia applications or a smoother desktop experience 4GB: 55 the top-notch model, with an amount of RAM that removes any limit no matter what you do with your Raspberry Pi 4 The memory split that used to be the basic resource configuration for the GPU is not (almost) gone.
