Well the other cores may be busy doing things for the GPU driver (like copying data or compiling shaders) or things unrelated to PPSSPP but the actual rendering done by the GPU build into your CPU would typically not show up as CPU load.
Also, most mobile GPUs share their main memory with the CPU (with the exception of a local cache) as far as I know.
