bandwidth of different clImage format and efficient access pattern

Hi,

    Per OpenCL Developer Guide (as shown below), I find that max bandwidth of each sampler is 64 Byte/cyc:

https://software.intel.com/content/www/us/en/develop/documentation/iocl-opg/top/coding-for-the-intel...

    My questions are:

1. Which clImage format with (efficient access pattern) can achieve max bandwidth?

2. Does different clImage format has a max texel/cyc when read by sampler? If yes, where can I find the data for common-used format?

3. What's efficient access pattern to read clImage by Sampler?

    Thanks!
