I have been maintaining a table by hand with various performance metrics – both on the website and separately in Google Sheets. In addition to the extra work required, I also by nature only put some of the columns. So … Continue reading →
Phoronix has published its roundup of benchmark/performance/review articles – https://www.phoronix.com/news/January-2024-Highlights Included were 10 articles with reviews and benchmarks. I’ve been keeping up with CPU workloads listed and now >130 workloads total. I haven’t added GPU/graphics tests because I haven’t developed … Continue reading →
I am now close to 100 overall phoronix tests added. Recent articles still include a number of new benchmarks, typically I have ~2/3 of the ones in an article and then need to add the remaining ones. However, over time … Continue reading →
I am now up to 50 phoronix workloads as summarized on the workloads page. For each one I have a graph and some pages of information. My general idea is to take the benchmark-based Phoronix articles and see if I … Continue reading →
I have not enhanced the topdown tool with ability to print process trees. This enables the key features of my previous “wspy” command. The interfaces is as follows. I added the following options to topdown to record process information: The … Continue reading →
I have made several enhancements to the topdown tool. I also have some fragile things I still need to sort out along the way. The net combination is best seen below where I include both a topdown metrics summary (created … Continue reading →
By default, counters were not available to measure l3 and df counters on AMD. With some help from likwid documentation I figured out what is going on and how to get it enabled. The first thing to do is see … Continue reading →
I have looked through the Family 19h PPR reference, output from “perf list -v –detail” and also some likwid counter groups to figure out combinations of counters I might be able to add as instrumentation options for a topdown command. … Continue reading →
I have updated and enhanced the topdown tool and also used this as an occasion to explore Zen4 topdown performance counters, Intel hybrid CPU while building something to compare Intel i5-13500H and Ryzen 7940 processor metrics. The interface might change, … Continue reading →
I have set up a new Intel performance machine for experiments. The processor is a i5-13500H in a Geekom MiniIT13 mini-PC. Following are some of the major parameters. This comparison is with Ryzen 7840 which will be my AMD comparison … Continue reading →
