In a bit of an unexpected move, Intel has announced today that from this point forward, they will no longer display multi-core boosts clocks for their CPUs. What this means is that Intel will now only show the maximum boost clocks for a single core on their CPUs.

This is a bit of a strange decision as this means that from now, only the base clock and the Turbo Boost 3.0 clock (which affects a single core on a CPU) will only be advertised and the maximum clocks on all cores under load wont be shown. This can lead to customer confusion as the Turbo Boost 3.0 frequency listed may be perceived as the maximum possible clock guaranteed on all cores.

Intel may have done this for a legal reason as the multi-core clock may not be guaranteed on all chips and various factors affect core clocks differently, such as the motherboard used, type and efficiency of cooling etc. Binned chips also differ greatly in terms of the maximum clocks that may be achieved.

Intel has been quoted by eteknix as follows:

“[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.”

Processor Cores / Threads Base Clock Turbo 2.0 (6c) Turbo 3.0 (1c) L3 TDP Price
Core i7 8700K 6/12 3.7 GHz 4.3 GHz 4.7 GHz 12 MB 95 W $359 / €389
Core i7 8700 6/12 3.2 GHz 4.3 GHz 4.6 GHz 12 MB 65 W $303 / €327
Core i5 8600K 6/6 3.6 GHz 4.1 GHz 4.3 GHz 9 MB 95 W $257 / €273
Core i5 8400 6/6 2.8 GHz 3.8 GHz 4.0 GHz 9 MB 65 W $182 / €192
Core i3 8350K 4/4 4.0 GHz NA NA 8 MB 91 W $169 / €189
Core i3 8300 4/4 4.0 GHz NA NA 8 MB 65 W
Core i3 8100 4/4 3.6 GHz NA NA 6 MB 65 W $117 / €123


Basically, by looking at the chart above, the Turbo Boost 2.0 (greyed text) will not be listed or advertised from this point forward by Intel.
