Multi-Core Performance speedup with(out) hyperthreading

kttrs1 · 07-11-2010, 09:33 PM **#11**

Hey all, running the emu on a core i5 laptop. When ever i run a game my cpu stats show 16 cores. Is this normal for the rest of you? Not sure if i should file this as an issue or not.

Also Disable HT ( Hyper Threading ) In your BIOS.

And also and I have a question for you about the performance on your i5 Laptop...

Im getting a i7 extreme edition m15x ; I was wondering how was the performance on Super Mario Galaxy and LOZ: TP...

And if you over clock or not ?

OR u can use something like this and assign cores via batch file :-)
edit to your needs.

Code:

@echo off

@rem echo on

CD "C:\Program Files\Dolphin\"

start Dolphin.EXE

@rem start /HIGH Dolphin.EXE

@rem use both CPU-0 and CPU-1

@rem wfcpuuse Dolphin.EXE 3

@rem use CPU-1 only

@rem wfcpuuse Dolphin.EXE 2

@rem use CPU-0 only

wfcpuuse Dolphin.EXE 1

@rem pause

no need to turn off HT

Weirdly I have never had this problem on my i7, turning off HT does not impact my performance in anyway. I have never seen activity on my HT'ed cores when running dolphin, except for the time I was running LLE + LLE on a separate thread. I know HT is working because when I am converting video all my cores are used.

the bios on my lappy does not have the option to disable HT so i just use core affinity.

performance is solid. average about 85-90% speed off the top of my head in SMG1 with the latest revisions. turbo mode does kick cpu to 2.5ghz
gpu is 360m equal to a desktop 8800gt
