[AM335x]The performance and benchmark of decoding H.264

Hello.

In the following wiki page, there is AM335x's performance and benchmark table.
http://processors.wiki.ti.com/index.php/ARM_Multimedia_Users_Guide#CPU_and_Memory_load

I have a few question about it.(Especially, about H.264.) Could anyone please answer my questions?

Q1:
About 480p column and WVGA column in H.264 row, as CPU Frequency becomes low, the CPU load is down.
Why?

Q2:
About 480p column and WVGA column in H.264 row, CPU load of WVGA is lower than 480p.
Why?

Best regards,
Keigo Ishii
