It runs at 1.5GHz and is a 64-bit processor with 1MB L2 cache, 32KB L1.<\/li>\n<li>A range of memory options (3200-LPDDR4) &#8211; the Pi 4 is available in 1GB, 2GB and 4GB flavours. Pricing varies accordingly.<\/li>\n<li>A graphics\/video processor capable of delivering H265 video up to 4Kp60 over two micro-HDMI ports.<\/li>\n<li>Improved networking &#8211; for wifi fans, you still get dual-band wireless (2.4GHz and 5GHz) and for wired networking a massive improvement to (<a href=\"https:\/\/www.recantha.co.uk\/blog\/?page_id=12324\">bitchin&#8217; fast<\/a>) Gigabit Ethernet which no longer runs through the restrictive USB bus.<\/li>\n<li>4 USB ports &#8211; two are USB 3.0 and two are the traditional USB 2.0. These are driven by a PCIe USB host with integrated hub.<\/li>\n<li>Power for the Pi 4 is delivered by a USB-C port which also allows an OTG connection.<\/li>\n<li>Power-over-Ethernet capability via the PoE HAT, as per the 3B.<\/li>\n<li>40-pin GPIO header as always, thus maintaining backwards-compatibility. However, these pins have added &#8220;oomph&#8221; because of additional &#8220;alt&#8221; modes giving us 4\u00d7 UART, 4\u00d7 SPI, and 4\u00d7 I2C connectors.<\/li>\n<\/ul>\n<p>More technical information can be found in <a href=\"https:\/\/www.raspberrypi.org\/documentation\/hardware\/raspberrypi\/bcm2711\/rpi_DATA_2711_1p0_preliminary.pdf\" target=\"_blank\" rel=\"noopener noreferrer\">the official Raspberry Pi preliminary datasheet<\/a>.<\/p>\n<h2>Pricing<\/h2>\n<p>As always, Raspberry Pi has delivered on their pricing target. The base unit (with 1GB of memory) comes in at $35. The 2GB option costs $45 and the 4GB board costs $55. This translates, for UK customers, to around \u00a333, \u00a343 and \u00a353. Resellers have been given some leeway to set their own pricing, so you may find a certain variation across outlets. The stated prices will be kept in the physical shop in Cambridge and Pi 4 will be available there from day one.<\/p>\n<h2>Where can I get one?<\/h2>\n<p>Naturally, only official re-sellers will have the Raspberry Pi 4 for launch.

You will likely find that basic physical computing (including basic robotics) only needs the 1GB version, whereas if you&#8217;re using it as a desktop platform, browsing and office applications eat up memory, so you might be best advised to go with the more expensive 4GB version.

Whether you end up using the dual functionality depends on your use case. I can imagine that industry, in particular, will sit up and take notice of this &#8211; many Pis are used for digital signage, so the dual outputs will let companies run two screens from one Pi. Using the dual outputs as some sort of &#8220;extended desktop&#8221; is something I haven&#8217;t tried yet (although <a href=\"https:\/\/twitter.com\/geeky_tim\" target=\"_blank\" rel=\"noopener noreferrer\">Tim has<\/a>, to great success), but that&#8217;s the use case for office and development users. One thing that <em>is <\/em>a shame is that the ports aren&#8217;t full-sized HDMI. This means that you&#8217;ll need adaptors or all-new cables. This was simply because they weren&#8217;t able to fit the full-sized sockets on the Pi and still keep the form-factor. One thing to note: the &#8220;dual outputs at 4Kp60&#8221; is &#8220;in theory&#8221; at this point. There were issues amongst the testers getting the Pi to run fast enough to be able to cope with this kind of high-end use, but I&#8217;m hopeful they&#8217;ll fix that &#8220;in software&#8221; fairly soon.<\/p>\n<p>Networking improvements, giving us Gigabit Ethernet, are sure to make those wishing to run Pis as servers extremely happy. It has been a long time coming, and getting the Ethernet away from the USB chip is a massive improvement &#8211; no more restrictions on speed and throughput.<\/p>\n<p>Also of note to server users is the inclusion of 2 USB3 ports. This means that you can, for example, now use SSDs at 200MByte\/s without breaking a sweat. Media Centre users are likely to be happy for the same reason &#8211; Gigabit Ethernet and USB3 are a sweet combination.<\/p>\n<div id=\"attachment_19525\" style=\"width: 810px\" class=\"wp-caption alignnone\"><a href=\"https:\/\/i0.wp.com\/www.recantha.co.uk\/blog\/wp-content\/uploads\/2019\/06\/USB_ENET_CU-Edited.jpg?ssl=1\"><img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-19525\" class=\"wp-image-19525 size-full\" src=\"https:\/\/i0.wp.com\/www.recantha.co.uk\/blog\/wp-content\/uploads\/2019\/06\/USB_ENET_CU-Edited.jpg?resize=560%2C246&#038;ssl=1\" alt=\"\" width=\"560\" height=\"246\" srcset=\"https:\/\/i0.wp.com\/www.recantha.co.uk\/blog\/wp-content\/uploads\/2019\/06\/USB_ENET_CU-Edited.jpg?w=800&amp;ssl=1 800w, https:\/\/i0.wp.com\/www.recantha.co.uk\/blog\/wp-content\/uploads\/2019\/06\/USB_ENET_CU-Edited.jpg?resize=300%2C132&amp;ssl=1 300w, https:\/\/i0.wp.com\/www.recantha.co.uk\/blog\/wp-content\/uploads\/2019\/06\/USB_ENET_CU-Edited.jpg?resize=768%2C338&amp;ssl=1 768w, https:\/\/i0.wp.com\/www.recantha.co.uk\/blog\/wp-content\/uploads\/2019\/06\/USB_ENET_CU-Edited.jpg?resize=560%2C246&amp;ssl=1 560w, https:\/\/i0.wp.com\/www.recantha.co.uk\/blog\/wp-content\/uploads\/2019\/06\/USB_ENET_CU-Edited.jpg?resize=260%2C114&amp;ssl=1 260w, https:\/\/i0.wp.com\/www.recantha.co.uk\/blog\/wp-content\/uploads\/2019\/06\/USB_ENET_CU-Edited.jpg?resize=160%2C70&amp;ssl=1 160w\" sizes=\"auto, (max-width: 560px) 100vw, 560px\" \/><\/a><p id=\"caption-attachment-19525\" class=\"wp-caption-text\">The Ethernet and USB ports have swapped sides!<\/p><\/div>\n<p>One very important thing to note: the USB ports and Ethernet port have &#8220;swapped sides&#8221;, making the Pi 4 incompatible with every single Pi case there is out there.

Note the new adjacent power circuitry.<\/p><\/div>\n<p>The use of USB-C for power is sure to be controversial &#8211; suddenly all those microUSB power supplies that you&#8217;ve got are likely to be redundant, at least in as far as using them with the Pi 4 is concerned. The power usage of the Pi 4 is higher than the Pi 3B+, hence the need for the change (as well as just keeping up with the times) so a straight adapter with a microUSB supply <em>may<\/em> not cut it if you&#8217;re using high-powered USB peripherals. The USB-C connector supports 5V at 3A, so the (generally) 2.5A microUSB supplies you get may result in the infamous power symbol appearing at times. The OTG connection is a nice touch &#8211; perhaps this could be used to make physical computing via a normal Windows\/Mac over-the-cable possible?<\/p>\n<p>Great to see them maintaining compatibility with GPIO peripherals with the 40-pin header. This, I&#8217;m sure, will prove a relief to companies such as Pimoroni and Pi Supply who develop their own add-on boards. It also makes good business sense for Raspberry Pi as it means their own SenseHAT and PoE HAT will be compatible out-of-the-box.<\/p>\n<h2>Conclusion<\/h2>\n<p>As always, Raspberry Pi has delivered significant improvements whilst maintaining their desired price point. As technology moves on, better components are available for the Pi, albeit slightly behind-the-times as was always the case. Nowadays, mobile phones have Octacore and sometimes Decacore processors &#8211; the Pi&#8217;s processor is modest in comparison, but because it&#8217;s been designed specifically for the Pi, it punches above its weight. The inclusion of different memory packages, depending on how much you&#8217;re willing to pay, is a great touch and should cut down on the moans from those people who use the Pi as a desktop replacement or development machine. <em>I&#8217;m even tempted to try getting Sublime Text to work on the Pi so I can develop at work on it, but that&#8217;s another story!<\/em><\/p>\n<p>Perhaps the most ground-breaking part of this upgrade is the combination of Gigabit Ethernet on it&#8217;s own (without tying it into the USB chip) with USB3 ports which is sure to get those wanting to run the Pi as a server running to their nearest outlet to get hold of one.<\/p>\n<p>I think the most interesting thing on the Pi 4, though, is the dual video outputs, clearly designed for industry. <em>It does make me wonder, though, whether this is what your typical home or school user really wants, and what was sacrificed to make it more appealing for industry. For a while now, Raspberry Pi Trading has clearly re-aligned themselves to develop products which will sell better in industry. This is hardly surprising &#8211; Eben Upton has been quoted as saying that over 50% of sales are into industry &#8211; but I keep wondering if the original mission of Raspberry Pi is being left behind in order to achieve more sales. I don&#8217;t know whether this is &#8220;a bad thing&#8221;, you understand. Every sale of the Pi means there&#8217;s more money to be ploughed back into <a href=\"https:\/\/www.raspberrypi.org\/about\/\" target=\"_blank\" rel=\"noopener noreferrer\">the Educational mission of the Raspberry Pi Foundation<\/a>. Is there a disconnect between the hardware and the mission? Does it matter?
