One of the great strategies to boost performance is clock boosting. Intel was the first to bring it to the masses with their Turbo Boost. Over time, we?ve seen many other chips adopt similar methods to help boost performance. Generally, Intel reveals the turbo bins for the different core workloads. In a surprise twist, Intel will no longer be making public some crucial Turbo Boost clock speed information.
Starting with the current crop of processors, Intel will only detail the base and single-core Turbo speeds. This means we lose out on the Turbo clock speed information for any other multi-core workload. This changes a long-term practice since Turbo Boost was first debuted by Intel. Due to this change, we are losing a lot of info from Intel useful for overclocking.
?[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.?
There are several reasons that Intel may be making this change. Firstly, it could be due to legal issues. By no longer publicizing Turbo speeds, the user will have no guaranteed Turbo clocks. It also makes it a lot harder to compare CPUs as some chips may have a multi-core Turbo closer to either the stock or boost clock than others. Another could be binning less than perfect chips. By having a shifting multi-core Turbo, Intel just needs to make sure one core hits peak Turbo and the rest the stock clock. Depending on the chip, the multi-core boost could be set at any speed. This brings a whole new dimension to the silicon lottery.
