Sorry, but what are you comparing with? G505S is a laptop, not a desktop. and G505S laptop has been sold with different CPUs (which are removable), as well as at least three motherboard versions! ( only integrated GPU / integrated + HD 8570M discrete / integrated + R5 M230 discrete ) That A6-5350M cpu you have been comparing to - could be found at the very low end version of G505S, and this A6 is probably not even supported by coreboot Most (if not all) of G505S+coreboot owners here - have A10-5750M AMD CPU which is a powerful quad core CPU with functional virtualization, not 2 core weak A6-5350M So, this link should have been http://www.cpu-world.com/Compare/815/AMD_A10-Series_for_Notebooks_A10-5750M_vs_Intel_Core_i5_Mobile_i5-3360M_(BGA).html Looks like the performance of A10-5750M (G505S cpu) and i5-3360M (X230 cpu) is almost the same, but now we should substract 5-30% or even more from i5-3360M benchmarks - because the Meltdown vulnerability, for which this horrible "5-30% or even more slowdown patch" is required ---> is Intel specific vulnerability ( cpu_insecure , as reported by Linux kernel ) And... "thanks" to Intel Meltdown, the results are suddenly very favorable for A10-5750M CPU, and for G505S in general Best regards, Ivan Ivanov 2018-01-11 8:34 GMT+03:00 [799] via coreboot <[email protected]>: > Hello, > > Off-topic: > Top-posted as Protonmail Android App is still unable to correctly use inline > answers without correct quote layout/line breaks.
