Question  06-10-2020, 11:09 AM
I have a Win10 x64 PC with i5-3450. When I run hashcat 5.1.0 with Intel® CPU Runtime for OpenCL™ Applications 18.1 installed, I can get about 245 mH/s for NTLM hash.

However, if I uninstalled that CPU-only runtime and installed the latest Intel® Graphics Driver for Windows 15.33.50.5129, the speed is much slower, only 90775.0 kH/s.

Is it normal?

You don't need to uninstall certain opencl runtimes to only run certain kinds of devices. Hashcat provides options to choose which device(s)/device types to use.

The onboard GPU being slower than the CPU does not seem too unlikely. The purpose of a onboard GPU is merely providing some base function. Not much power in there.

But it should be possible to use CPU+onboard GPU at the same time for some speed gain.
