Intel is no longer going to disclose all-core Turbo Boost speeds, starting with their 8th Gen Coffee Lake processors that have just been released. The information comes straight from the blue giant. Answering a query from ExtremeTech on the matter, the company said that "[W]e're no longer disclosing this level of detail as its proprietary to Intel. Intel only specifies processor frequencies for base and single-core Turbo in our processor marketing and technical collateral, such as ARK, and not the multi-core Turbo frequencies. We're aligning communications to be consistent. All Turbo frequencies are opportunistic given their dependency on system configuration and workloads."

This decision is a rollback that does little more than rob users of another data point that has really always been there. The practical effect of this change isn't anything to write home about: Intel's Turbo Boost capabilities were never guaranteed performance levels (the fact that the advertised Turbo speeds were called "Max Turbo" implied Turbo levels could be lower.) However, there's also not much that can be said to explain this change in stance from the blue giant. If anything, this decision only opens up debate and speculation regarding the reasons why Intel is making this change: and the skeptics among us will always default to foul play or dark linings.To our Forum dwellers: this piece is marked as an Editorial
