We have been updating our internal accounting of stats for FLOPs for FAH. The major revamp has come from a better handling of the difference between a CPU and a core. Modern CPUs have multiple cores. Before the v7 client, it was common for donors to fold with multiple uni-processor clients, one for each core. Now, with v7 making SMP more easy to run, SMP is much more common. This means we need to keep track of CPUs and cores more explicitly. Our new serverstats page takes care of this and also updates for estimates for FLOPs across the board, but especially from GPUs.
Our goal in general is to be conservative with this reporting, but the old page was likely too conservative. The end result of the update is more accurate representation of the power of FAH today. The new page is located at: https://stats.foldingathome.org/os
