Best is power of 2 performance wise. Just stick to the dual system ;) 2x2,4x4,8x8,16x16,32x32,64x64,128x128,256x256,512x512,1024x1024,2048x2048 and so on. Power of 8 would be some completely unrelated number system. You can use somethine like 512x256 for example,which works quite as good as 512x512 but best is to stick to…
