![]() ![]() 4K contents can also be played in part also liquid, but this does not apply to all 4K content. Therefore, it is also suitable with restrictions as a media player, at least when the 1080p resolution is sufficient. Modern video codecs as well as H.265 / HEVC can decode the Raspberry Pi 4 b by hardware and usually play reasonably fluid. The Broadcom BCM2711 SOC is manufactured in an older 28 nm manufacturing and can therefore only be operated with relatively low clock frequencies before the SOC is heavily heated. This is not suitable for games or other more demanding tasks, but should only take over the image or video output of the Raspberry Pi. The CPU cores are based on the Cortex A72 design, the command set is ARMV8-A64 (64 bit).Īs an internal graphic, the SOC brings a Broadcom VideoCore VI with which has 4 execution units and 64 shaders. By configuration file, the processor on the Raspberry Pi 4 B can be overclocked, with good cooling usually 1.7 - 1.8 GHz are possible. The clock frequency is itself for ARM processors at low 1.5 GHz. CPU with the best price/performance ratioĭescription of the processorThe Broadcom BCM2711 is soldered on the Raspberry Pi 4 B mainboard and has 4 CPU cores.Both GPUs are supposed to have the same performance according to Wikipedia. We’ll have to wait and see here, as we don’t know at which frequency the GPU is running. Now if I compare the results to RK3288 (Mali-T764 GPU) based Ugoos UT3s TV box, the score on RK3399 (Mali-T860MP4) is also lower. The Mali-T860MP used in RK3399 is still far from the performance delivered by the Kepler GPU in Tegra K1. [ Update: I also found GFXBench 3D graphics results for RK3399, and compared it to Nvidia Tegra K1. Rockchip RK3399 is also faster than Nvidia Tegra K1 quad core Cortex A15 2.2 GHz for single thread performance, and about equivalent for multi-core tests. Rockchip RK3399 “reference” TV box also has 4GB RAM, so I’m expecting RK3399 devices to come with 2 and 4 GB versions. If you look into the details AES is over 10 times faster on RK3399, so there must be some special instructions used here, or AES hardware acceleration. There’s a significant single-core performance boost (+73%), and lower multi-core delta (+30%) as expected since RK3399 has 2 fast Cortex A72 cores, 4 low power Cortex-A53 cores, against 4 fast Cortex-A17 cores for RK3288. Let’s compare it against RK3288 which CPU-wise is the fastest processor I known of from Chinese silicon vendors targeting TV boxes. I’m not that familiar with GeekBench so number don’t tell me anything. The box is clocked at 1512 MHz, while the tablet is limited to 1416 MHz, but overall single-core score is about 1350 points, while multi-core score hovers around 2,550 points. We can have a first clue about the performance as Rockchip RK3399 boxes and one tablet are now showing up on GeekBench. Rockchip RK3399 hexa-core processor with ARM Cortex A72 and A53 cores and a Mali-T860MP GPU will soon be found in TV boxes, development boards, tablets, Chromebooks, virtual reality headset and more, and is widely expected to offer a significant performance boost against previous Rockchip processors, including RK3288, and outperform SoCs from competitors like Amlogic and Allwinner.
