New RK3568B2 Karaoke Machine Motherboard vs. Old RK3568 Motherboard

Currently, the SOC chips of the newly released KTV karaoke machine supporting motherboards are basically RK3568B2 with FCCSP636L plastic packaging (as shown in the figure below). The maximum frequency of B2 can reach 2GHz, while the frequency of the old RK3568 is generally up to 1.8GHz. In addition, the GPU of the B2 model has also been upgraded. For example, it has 32 shading units, while the old RK3568 only has16 shading units. Overall, the B2 has better multimedia performance.

The SOC chip of the old RK3568 motherboard is packaged with FCBGA636L metal (as shown in the figure below). Its heat dissipation performance is slightly better, but the supply of the old RK3568 processor is relatively tight. Now, the RK3568 board models that Dingchang has basically put into mass production are mainly RK3568B2.
