For most workloads, upgrading from CentOS 7 to CentOS 8.0 means significant performance improvements particularly on newer hardware platforms. This is especially true if building your common software from source where it means moving from a GCC 4.8 based kernel to now having GCC 8.2.1 and the many GNU Compiler Collection advancements made the past few years. (Granted there are ways via application streams and more for having newer packages on CentOS7/EL7, but this is strictly a stock/out-of-the-box look.)

The updated compiler as well as changes around the CPU frequency scaling drivers on RHEL8 / CentOS 8.0 means faster build times.

When firing up workloads focused on stressing the kernel, CentOS 8.0 generally is a great deal faster. CentOS 7 to CentOS 8.0 means jumping from an old Linux 3.10 kernel with tons of back-ported patches to now having a fresh Linux 4.18 kernel base.
