G2D function between 8M Quad and 8M Plus

hankwang — Fri, 13 Aug 2021 07:26:23 GMT

Hi,

We have a screen capture program that transmits the screen over the network ( like remote desktop). The program runs on the 8MP CPU, the CPU usage will be 97%. The program runs on the 8MQ CPU, the CPU usage will be 82%. When we enable the g2d function on the 8MP , the CPU usage will be 80-82% .

Why the 8MQ CPU not need to enable g2d function, the CPU usage rate is still relatively low?

Hi Hank

CPU usage rate may be low due to larger L2 cache, 1MB vs 512KB in 8M Plus.

Best regards
igor
