Details are there in appropriate pages. > C5 instances feature the Intel Xeon Platinum 8000 series (Skylake-SP) processor with a sustained all core Turbo CPU clock speed of up to 3.4GHz, and single core turbo up to 3.5 GHz using Intel Turbo Boost Technology. C5 instances offer higher memory to vCPU ratio and deliver 25% improvement in price/performance compared to C4 instances, with certain applications delivering greater than 50% improvement. C5 instances provide support for the new Intel Advanced Vector Extensions 512 (AVX-512) instruction set, offering up to 2x the FLOPS per core per cycle compared to the previous generation C4 instances. https://aws.amazon.com/ec2/instance-types/c5/ https://aws.amazon.com/ec2/instance-types/c5/ Haven't looked up details for the new stuff yet, might take some time to be up.
