In-Depth Information
GPU Frequency
The
gpu_freq
option determines the following other values:
Parameter
MHz
core_freq
Core frequency
h264_freq
H.264 frequency
isp_freq
Image sensor pipeline frequency
v3d_freq
3D video block frequency
The
gpu_freq
parameter has the following default value:
gpu_freq
Description
250
Default GPU frequency (MHz)
Core Frequency
The
core_freq
option allows the user to configure the GPU processor core clock.
This parameter also affects the ARM performance, since it drives the L2 cache.
core_freq
Description
250
Default in MHz
Minimum Core Frequency
When dynamic clocking is used, this sets the minimum GPU processor core clock rate.
See also the
core_freq
option. Like the
core_freq
option, this parameter affects the ARM
performance, since it drives the L2 cache.
core_freq_min
Description
250
Default in MHz
