Do Manufacturers Guarantee Turbo Frequencies?

The question: ‘do manufacturers guarantee turbo frequencies?’ seems like it has an obvious answer to a lot of people. I performed a poll on my private twitter, and the voting results (700+) were astonishing.

31% of people said yes, 69% of people said no.

The correct answer is No, Turbo is never guaranteed.

To clarify, we need to define guarantee:

"A formal assurance that certain conditions will be fulfilled - if pertaining to a product, then that product will be repaired or replaced if not the specified quality."

This means that under a guarantee, the manufacturer would be prepared to repair or replace the product if it did not meet that guarantee. By that definition, Turbo is in no way under the guarantee from the manufacturer and does not fall under warranty.

Both AMD and Intel guarantee four things with their hardware: core counts, base frequency, peak power consumption at that base frequency (in essence, the TDP, even though strictly speaking TDP isn’t a measure of power consumption, but it is approximate), and the length of time those other items are guaranteed to work (usually three years in most locales). If you buy a 6 core CPU and only four cores work, you can get it replaced. If that six core CPU does not hit the base frequency under standard operations (standard is defined be Intel and AMD here, usually with a stock cooler, new paste, a clean chassis with active airflow of a minimum rate, and a given ambient temperature), then you can get it replaced.

Turbo, in this instance, is aspirational. We typically talk about things like ‘a 4.4 GHz Turbo frequency’, when technically we should be stating ‘up to 4.4 GHz Turbo frequency’. The ‘up to’ part is just as important as the rest, and the press (me included) is guilty of not mentioning the fact more often. Both Intel and AMD state that their processors under normal conditions should hit the turbo frequency, and both companies actively promote frequency enhancing tools such as aggressive power modes or better turbo profiles, but in no way is any of this actually guaranteed.

Yes, it does kind of suck (that’s the technical term). Both companies market their turbo frequencies loudly, proudly, and sometimes erroneously. Saying something is the ‘first X GHz’ processor only really means something if you can actually get into a position where that frequency is guaranteed. Unscrupulous retailers even put the turbo frequency as the highlight in their marketing material. Trying to explain to the casual user that this turbo frequency, this value that’s plastered everywhere, isn’t actually covered by the warranty, isn’t a good way to encourage them to get a processor.

    jaxidan, as this article stated, intel OR AMD don't guarantee the turbos, or max boost the cpus can reach.

    Maybe the retail box should indicate that to avoid false advertising.
  • Korguz - Tuesday, September 24, 2019 - link

    right after intels retail box, also states how much power its cpu's really use as well :-)

    Someone doesn't understand what the word "Max" means... Here, I'll help you. "Maximum" literally = "Up to".

    I think the perception that people have about turbo frequencies (based on Intel experience) is that buying a high-end system with DIY water-cooling would lead to near max or over max clock frequencies. Since you can buy a lower-end AMD motherboard and average cooling solution and get the same results, this leads to disappointment from the end-user. With Intel, it felt worth it to spend the extra money in some cases. With AMD, it has me re-evaluating how I view building a PC. I have still not upgraded from my 4770K at 4.7GHz because it feels like we need more settling on the AMD side and need to see what INtel brings out by year's end.

    At the end of the day, even though I know we aren't guaranteed turbo frequencies, Intel has spoiled us and if you are going to post a number on your box, there should be a way to hit it in some cases wtih some CPUs.

    Dr. Ian Cutress Yet another Pro-Intel Article?
  • Korguz - Tuesday, September 17, 2019 - link

    how is this pro intel ?? did you even read it ?? he is trying to explain how the turbo speeds work.. and how intel and AMD go about getting them.
  • ianisiam - Wednesday, September 18, 2019 - link

    This is a well-researched, even-handed, and readable retelling of a very complex issue. There's no shilling to be found here.

    ROFL... and I am the one painted as the AMD fanboy... get lost, it is an awesome article.

    Anandtech being Anandtech yet again! Kudos!
