Performance - CPU-Z

CPU-Z Internal Benchmark

CPU-Z was recently updated with a fairly quick to run, yet seriously proper benchmark. I decided to include the results as it offers something you can easily replicate and try at home. Next to that, it actually is a pretty nice performance measurement to test RAW CPU performance, next to that the performance is measured both as per core and multi-threaded core performance.


The CPU-Z benchmark really is becoming one of my favorite ones, as it offers a fast and easy manner to to quickly view single treaded and multi-threaded SMT performance. Give it a try yourself, it is easy to use. Here are some numbers, we'll build up more results over time:


At single core performance it's all about clock frequency and IPC (how fast one core is). The Ryzen 7 1800X at a boost of 4.0 GHz positions itself really well. Next to that is the fact it can turbo a little extra if a smaller number of threads is used, hence we spotted Ryzen 7 1800X with a single thread stressed at even 4100~4200 MHz at one point. And yes, that means properly fast single-threaded performance. But I'd rather follow the single thread Cinebench results as shown on the next page.


Once you start to accumulate more cores the relative perf will jump up fast, of course. Unfortunately not all software makes use of many cores/threads, including games, hence per core perf matters more opposed to having, say 8 cores over a quad-core processor.

For Ryzen 7 this works in a pretty similar fashion but the eight cores all get higher clocks, under full load the processors cores all are doing a good 3.7 GHz. That is pretty nice performance for a 499 USD processor for sure as the performance surpasses anything in its path. Obviously this is as synthetic a test as it gets though. 

Now I am going to add one last result set:


All processors above are clocked at 4.2 GHz, isolated you are looking at per core clock performance. Now 4.2 GHz was not stable on our Ryzen 7 1800X processor (as we have to OC ALL cores to 4.2 and not just one bin), we had to perform this test 3x. However this is indicative of the massive step AMD has made IPC wise. This kind of perf will also be indicative for the upcoming 6 and 4 core Ryzen SKUs.


Okay, one more: if you run all cores at say 4.0 GHz (again, all cores and all 1800X CPUs can do this) the above would be your end result.
