Intel/AMD TDP/PD/Freq

Having problems installing that new stick of memory? Found some great software or having issues with something? Or maybe want to chat about your PlayStation, X-Box, Nintendo, Sega, even your old Spectrum 48k....! Or maybe something you want to sell or acquire (computing related of course!). Let us know here...

Intel/AMD TDP/PD/Freq

Post by chriscambridge »

Just found this image which may or may not be useful to others!

https://www.kitguru.net/components/cpu/ ... review/11/

As you can see it shows the freq range, TDP, and power draw across some of the more recent AMD and Intel CPUs; very useful if you want to see the difference between TDP and actual power draw (at the wall socket).

Image

Please note that which was stated:
We leave the system to idle on the Windows 10 desktop for 10 minutes before taking a power draw reading. For CPU load results, we read the power draw while producing approximately 5 minutes worth of runs of the Cinebench R20 multi-threaded test. We also run the Blender Classroom Rendering stress test.

Both Cinebench and Blender are used instead of synthetic stress tests such as AIDA64. This is because some CPUs – most notably Intel’s HEDT Core processors when operating under default turbo conditions – will heavily reduce their clock speed with the AVX-based AIDA64 workload, thus giving an unrepresentative reading.

The power consumption of our entire test system (at the wall) is shown in the chart. The same test parameters were used for temperature readings.

Hey Damien, can you still see the image? I moved it to Imgur.com so I could add it to the post rather than hot-linking it..
