− | == Processor ==
| + | |
− | The Rockchip RK3399 Soc used in ROCK Pi 4 includes 64bits hexa core processor with dual 1.8GHz Cortex-72 and qual 1.4GHz Cortex-A53, Mali T860MP4 graphics processing unit (GPU) and Internal SRAM. It has a level 1 (L1) cache and a level 2 (L2). For level 1 cache, 48KB Icache and 32KB Dcache is for each A72. 32KB Icache and 32KB Dcache is for each A53. For level 2 cache, 1024KB cache is for big cluster and 512KB cache is for little cluster.

− | == Networking ==
| + | |
− | On the ROCK Pi 4 Model A, B board, the Giga Bit Ethernet port is provided. From the test result, we know that the bandwidth is at least 939Mbits/sec. If you are interested in POE (Power Over Ethernet), you should try it on the Pi 4 board.
| + | |
− | <br />The ROCK Pi 4 Model B is equipped with 2.4GHz 802.11 b/g/n and 5G ac/a WIFI. The Pi 4B also features Bluetooth 5.0.
