Still no way to get 16+ cores without huge amounts of RAM (and cost). My workloads are CPU bound but not particularly memory intensive.

- AWS_F1 8y agoDid you consider C5/C5d ? they typically get to 3.5Ghz and have smaller DRAM/vCPU ratio
- voltagex_ 8y agoC4 spot instances work for me at the moment. The price increase for C5 wasn't worth it as I was only seeing a 5-10% performance increase. I need to re-benchmark though.
- Johnny555 8y agoThe price increase for C5 wasn't worth I don't know about spot pricing, but on demand pricing for c5's is about 15% less than the c4's. If you look at c5d's with ephemeral storage they are still a bit cheaper than c4's.
- paulddraper 8y agoc5.4xlarge * 16 vCPU at 3.0 GHz/3.5 GHz Turbo * 32 GB RAM * $0.68/hr on demand, $0.43/hr reserved, ~$0.24/hr spot You could argue that's too expensive, but the cost is coming from the compute, not the 32 GB of memory.
