Yield rate of the Intel Core i9 13900K (Question)

[WeiSheiLindon]

I'm currently working on an essay about how technology has become more affordable and opened the doors to different creative processes over the last 20 years, and have spent countless hours researching processors new and old. The last bit of information I need is a percentage yield rate for the Core i9 13900K, that's to say the average percentage of functional processors from each silicone wafer. It doesn't need to be directly from intel, but I don't have the knowledge to make an estimate, so any information would be appreciated. Thanks!

That's not information they make public. If you google around you can find general numbers for the industry.

yeah thats gonna have to be an educated guess form people that do business reports etc..

Cannot imagine intel saying oh oh oh we have bad yeilds as it just lets any competitor in that segment privvy to info intel would rather keep quiet about.

Conversely if the yeilds were magical and extremely high the consumers would be quick to shout for price reductions......

good luck with the research and check places where they discuss intel stocks and shares etc as often snippets of info and guesswork related to yeilds might be found.

You can estimate something as follows:

Use a silicon yield calculator. e.g. https://isine.com/resources/die-yield-calculator/

• Wafers used are 300mm
• Physical size of the CPU die - 257mm² as 23.8x10.8mm https://videocardz.com/newz/intel-i9-13900-raptor-lake-cpu-has-been-delidded-revealing-257-mm²-die
• Defect rate - I'm not sure if Intel ever published this. For indication, TSMC defect rate for 7nm and 5nm is about 0.1. https://www.anandtech.com/show/16028/better-yield-on-5nm-than-7nm-tsmc-update-on-defect-rates-for-n5
• Other values can be left at default unless you really want to dig into them

Note the yield only considers dies without defect. It doesn't consider binning at all, so not all "good" chips might hit the required clocks. It doesn't consider that some defects can be mapped out (e.g. by disabling cores) which could increase the yield by producing lesser core products.

Thanks, this is very useful information, you've just saved me many hours of research.

 

If anyone is curious, using this calculator, the yield rate for the Intel Core i9 13900 should be about 77.8%.

 

The variables used were a die size of 23.8 x 10.8, wafer diameter of 300MM, a defect density of 0.1/CM², and an edge loss of 5MM.

 

Due to the confidentiality of Intel's manufacturing processes, this is just an estimate, and uses several assumed variables (Such as defect density, and edge loss. Edge loss could likely be calculated, but I don't have the knowledge to perform such a calculation), as a result of that.
