Calculating Hardware Compute Requirements

Different Codecs require different hardware processing power. Below are some calculations and samples you can use to assist with selecting the best hardware to meet your production requirements.

e.g. 1: Intel® Xeon® Gold 6226R Processor : 2.9GHz x 16 = 46.4GHz

e.g. 2: Intel® Core™ Core i9-13900K Processor : 3.0GHz x 24 = 72GHz

e.g. 2: Intel® Core™ Intel Core i7-13850HX Processor : 2.1GHz x 20 = 42GHz

You can use the table below to help you determine your CPU requirements based on the format/framerate and number of channels your require for your production.

eg 1: Lets say you need to ingest 6 channels of 1080 60p to DNxHD: Therefore your would need 6 X 11.6 = 69.6GHz so based on the above rule of thumb a Core i9-13900K or a dual Xeon® Gold 6226R would be required.

eg 2: 8x 1080 50i to XDCAM = 8 X 5.8 = 46.6Ghz so based on the above rule of thumb a single Xeon® Gold 6226R would be the minimum required.

Keep in mind that your video I/O channels and storage/network throughput will also need to be considered.

Below is a table giving samples of the number of channels different processors should be able to handle. If you would like to use a different processor you can use the the rule of thumb to determine your total GHz and the “Power Required per Codec per Ingest Channel (GHz)” table above to calculate your expected channel count.

^*XAVC processing:

XAVC encoding is intensive and requires additional hardware cards

^**h264 processing:

Intel i7 and i9 processors include Intel® Quick Sync Video which enables h264 encoding on the CPU

For h264 processing on Xeon based systems a GPU is required.

Recommended GPU’s:
