Ubuntu – CPU benchmarking utility for Linux

cpuperformance

I am looking for a utility that will benchmark CPU performance under single and multi threaded instances. At present I have an old rig with a dual core CPU (E7500) at 3.6 Ghz and I am looking at replacing it with a quad core CPU (Q9400) at 3.2 Ghz. I want to see if I will notice a performance improvement with the extra 2 cores (albeit with a drop in core speed). I will clock the CPU's with the same FSB (400Mhz) and the cache size is the same per CPU (1.5MB) and for what its worth I have 4GB ram (with potential to upgrade to 6GB)

My son mainly uses the PC for playing TF2 (which I am trying to still get working under Linux) and I also use it for some video encoding (MP4 to DVD)

I am thinking that I could be better off with the quad core but any feedback would be appreciated.

Actually there is a a tool named sysbench.

You can install it with:

sudo apt-get install sysbench

To CPU benchmarking you can do like

sysbench --test=cpu --cpu-max-prime=20000 run

where 20000 is like max event count.

It turned out that this problem was unrelated to the intel_pstate driver, because acpi_cpufreq, the other driver, reported better values but never set them. The OS had probably no control over this.

This is a issue that happens with certain Dell laptops when charging is broken in a way that the laptop is powered by AC but not charged. Fixing the hardware problem removes the problem. In this case, it was an almost invisible piece of cloth in the power connector that prevented electrical contact.

Ubuntu – temperature sensing utility for linux that will read a ryzen 1700 cpu

The kernel module that worked for me is it87 https://github.com/groeck/it87

I have an ASUS Crosshair Hero VI. https://rog.asus.com/forum/showthread.php?92313-linux-lm_sensors-it87-driver

I am using ArchLinux with the 4.11 kernel. To get it working I ran

sudo modprobe it87 force_id=0x8622
sudo sensors-detect

You may need to use a different force_id value. The recommended list from the repo is 0x8622, 0x8628, 0x8728, and 0x8732.

To get the module loaded at boot time I had to create the following files as root.

# /etc/modules-load.d/it87.conf
# Load it87 for Ryzen motherboard and CPU sensors
it87

# /etc/modprobe.d/it87.conf
options it87 force_id=0x8622
