TLDR, with low end or older CPUs, Battlemage GPUs have huge performance drops in CPU heavy games. Much greater than GPUs from AMD or Nvidia.
This drop is so big, it makes the B580 to have performance on par with a GTX 1060.
This means that buying a B580 to make a quick and cheap upgrade for an older or low end system, will have performance issues in several games.
Also, ReBar continues to be very important for Intel GPUs to have good performance. So make sure your system has this feature enabled.
Intel has been notified and is working to find out what is the problem with their drivers.
