ZCC Performance on RISC-V Cores

Benchmark results demonstrate the ZCC 4.0.0 toolchain's ability to optimize system performance across hardware platforms from multiple RISC-V partners, including Andes, HPMicro, Nuclei and XuanTie. Compared to the open-source GNU GCC 14.2.0 toolchain:

ZCC 4.0.0 can deliver an average performance improvement of 22% and a 20% better code density on CoreMark;

ZCC 4.0.0 can deliver an average performance improvement of 35% and a 42% better code density on the Dhrystone benchmark, under ground rules.
