How many Multi-Format Codec Engines does i3-1215u have?

slide — Thu, 19 Jan 2023 11:38:31 GMT

As the production page ( https://www.intel.com/content/www/us/en/products/sku/226269/intel-core-i31215u-processor-10m-cache-up-to-4-40-ghz-with-ipu/specifications.html ) of i3-1215u says it has TWO Multi-Format Codec Engines, I expect it could decode two 8k60p av1 videos simultaneously. However, the videos become choppy as soon as I start a second 8k60p av1 video.

In light of that situation, I did some digging and found discrepancies in the specs provided by Intel.

on (https://www.intel.com/content/www/us/en/products/platforms/details/alder-lake-p.html)

it says i3-1215UE, i3-1220PE, and i3-12300HE has only 1 single Video Decode Box.

But, if you go to their individual product pages, for example ( https://ark.intel.com/content/www/us/en/ark/products/227851/intel-core-i31215ue-processor-10m-cache-up-to-4-40-ghz.html ), they all claim they have 2 Multi-Format Codec Engines.

As Video Decode Box(aka. VDBOX) and Multi-Format Codec Engine are used interchangeably in various Intel documents. And on page 5 of ( https://www.intel.com/content/dam/develop/external/us/en/documents/vtune-for-media-apps-june2016-final-534008.pdf) , it even declares "VDBOX (also known as Video Box) holds the fixed function hardware blocks for encode and decode. It is also
sometimes referred to as MFX (multi-format video codec). "

It seems either the Alder Lake P overview page or all three production spec pages of i3-1215UE, i3-1220PE, i3-12300HE has communicated the spec of Multi-Format Codec Engines number incorrectly.

So, I am wondering how many multi-format video codecs does i3-1215U has? Is there any way for end user to verify the number of multi-format video codecs in the system?

I was looking at similar capabilities. I found a foot note on a slide stating that unless you are using dual channel memory your graphics will be UHD not Iris Xe. That's why they describe those i3's as Iris Xe eligible. If you are using a single stick of RAM, that is where the issue lies. I hope that solves your issue.
