Linux-5.2.8 configuration: Intel Atom x5-Z8330 and CONFIG_MATOM

This is not a support request; I'm mainly asking out of curiosity (that's why I'm posting this in lfs-chat).
My CPU is an Intel Atom x5-Z8330 (06-4c-04) (https://www.intel.com/content/www/us/en/products/boards-kits/compute-stick/stk1a32sc.html), and during the configuration of Linux-5.2.8 there is an item in 'Processor type and features' under 'Processor family' that says 'Intel Atom' (CONFIG_MATOM). The description says: 'Select this for the Intel Atom platform. Intel Atom CPUs have an in-order pipelining architecture and thus can benefit from accordingly optimized code. Use a recent GCC with specific Atom support in order to fully benefit from selecting this option.'. I'm not sure what that means. Does the GCC that's built during LFS/BLFS have such a 'specific Atom support' or what would it take to get that? LFS runs fine with the 'Generic-x86-64' option; I'm just wondering if I can get more out of this CPU.
Thanks a lot!
