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 sysbenchTo do CPU benchmarking you can use:
sysbench cpu runThis will run a single-threaded CPU benchmark. To use more than one thread, use:
sysbench --threads=16 cpu runAlternatively, one can use stress-ng. It has a CPU stress test as one of the many stress tests built into the tool. The cpu stress test contains many different CPU stress methods covering integer, floating point, bit operations, mixed compute, prime computation, and a wide range of computations.
Install using:
sudo apt-get install stress-ngTo see the cpu related stress methods use:
stress-ng --cpu-method whichTo benchmark, for example, matrix product for 60 seconds on 4 CPU threads, use:
stress-ng --cpu 4 --cpu-method matrixprod --metrics-brief --perf -t 60

But I recently was looking for a tool available in multiple "distros" (Termux not really being a distro) including Ubuntu, and while the above mentioned packages are a common good choice, I read here: that 7-zip has a built-in benchmarking tool! And 7zip can be found in nearly every distros repository.
To run a single-thread benchmark:7z b -mmt1
To run a multi-thread benchmark:7z b

# Chose one, and run it.
phoronix-test-suite run pts/cpu Benchmarks several real world CPU-heavy use cases like compression, encryption and databases.
Beware that pts/cpu and other benchmarks takes up a few gigabytes of disk space. This might imply that they have more realistic workloads.
Tested on Ubuntu 16.10.
