Raspberry Pi 4 Featuring Faster CPU, Up To 4GB of RAM Launched
'Raspberry Pi today introduced a new version of its popular line of single-board computer. The Raspberry Pi 4 Model B is the fastest Raspberry Pi ever, with the company promising "desktop performance comparable to entry-level x86 PC systems." The specifications are: A 1.5GHz quad-core 64-bit ARM Cortex-A72 CPU (~3x performance); 1GB, 2GB, or 4GB of LPDDR4 SDRAM; full-throughput Gigabit; Ethernet; dual-band 802.11ac wireless networking; Bluetooth 5.0; two USB 3.0 and two USB 2.0 ports; dual monitor support, at resolutions up to 4K; VideoCore VI graphics, supporting OpenGL ES 3.x; 4Kp60 hardware decode of HEVC video; and complete compatibility with earlier Raspberry Pi products. It starts at $35.' -- source: https://hardware.slashdot.org/story/19/06/24/141229 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Does it have a battery-backed-up clock yet?

Fun fact: the launch site itself runs on a cluster of 18 π4 machines <https://arstechnica.com/information-technology/2019/06/the-raspberry-pi-4-launch-site-runs-on-a-pi-4-cluster/>.

I think they just mean the GPIO. There are other incompatible changes, like in the external connectors, and you need a new version of Raspbian to boot it <https://www.theregister.co.uk/2019/06/24/raspberry_pi_4_model_b/>. Also the new, more powerful CPUs put out quite a lot more heat if you push them hard. This one may actually need some fans.
