Amazon Web Services announced the general availability of two new Amazon EC2 instance families powered by 5th Generation AMD EPYC processors, promising significant performance and efficiency gains for customers running demanding cloud workloads.
The memory-optimized, high-frequency X8aedz instances now offer the highest CPU frequency in the cloud at 5 GHz, delivering twice the compute performance and 31 percent better price-performance compared to the previous generation.
The instances support an ultra-high 32:1 memory-to-vCPU ratio with up to 3,072 GiB of memory, making them ideal for databases and electronic design automation workloads that require large memory footprints and fast single-thread performance.
AWS also launched the compute-optimized C8a instances, which deliver up to 30 percent higher performance and 19 percent better price-performance than the C7a line, with a 4.5 GHz maximum CPU frequency.
They provide 33 percent more memory bandwidth for latency-sensitive workloads and 57 percent faster GroovyJVM performance for Java applications.
In addition, AWS opened preview access for the M8azn general-purpose instances, which offer the highest maximum CPU frequency in the cloud at 5 GHz.
These instances deliver up to twice the compute performance of previous-generation M5zn instances and 24 percent higher performance than M8a instances, positioning them for gaming, high-frequency trading, high-performance computing and simulation modeling workloads.
