+30%

Rockchip RK3588 featuring Cortex-A76 and Cortex-A55 cores, 8K video decoding support, 4K user interface support,
an NPU 2.0 (Neural Processing Unit)

RK3588

The processor should have eight cores in a 4+4 dynamIQ configuration
 the new 8nm process is expected to increase performance by 20 to 30 percent, while the power consumption will be reduced by 40 percent.
 Mass production is expected for Q1 2020.

Rockchip Video Encoder DecoderThe company also showed a slide with their video encoder/decoder IP, and Gen3 should be in RK3588 since that’s the only one with an 8K 60 fps decoder using either AVS3 or H.266 (VVC). I’m quite confused with the Gen1 decoder since it shows AV1 implementation too, and as such should be new as well.
An 8K 60 fps video encoder is also in the works.



H266 (je savais même pas que c'était déjà prévu)
" le codec HEVC H.266 est en préparation et sa normalisation est attendue pour octobre 2020."
