- Core i7 7740K (QMM9 ES): Its base frequency is 4.30 GHz well (100 MHz more than 7700K) and its turbo frequency at 4.50 GHz (similar to 7700K). Hyper-Threading is enabled and has 8 MB of L3 cache. There is, however, a small subtlety. The Core i7 7700K is specified at 4.4 GHz in Turbo mode with all active cores and 4.5 GHz with a single active core. The Core i7 7740K is designed to operate at 4.5 GHz Turbo mode, regardless of the number of active cores. This makes it, in practice, a CPU at 4.50 GHz.
- Core i5 7640K (QMMA ES): Although more disappointing than expected, the Core i5 7640K is clocked at 4.00 GHz good base against 3.80 GHz for the Core i5 7600K Socket LGA1151. A priori it is a gain, except that here: its Turbo mode is located at 4.2 GHz for a single active core, 4.1 GHz with two active cores and ... 4.0 GHz - its basic frequency - with 4 active cores ! Values strictly identical to the Core i5 7600K and which return to the removal of Turbo mode in Quad Core mode. This is enough to annihilate the interest of the increase in the base frequency. Regarding the presence of Hyper-Threading, Intel's internal documents indicate that it is disabled, but we still have no confirmation from a source that actually has a working CPU. As soon as our sample has found a compatible motherboard (which will not be long), we will confirm this point. Nevertheless, given the marketing abuse that seems to constitute this range of processors, we now have little hope.
It remains with these CPUs that Intel intends to compete with Ryzen. The acceleration of the timing - they are now in the final validation stage - demonstrates this. Without ruling on their performance, these
Kaby Lake-X to resemble the time a joke in bad taste. Intel is obviously seeking (yet) to create novelty by all means to mask the lack of evolution in its architectures. These practices make us think of the detestable waltz of labels in the world of GPU. Should it be interpreted as a sign of excitement due to unexpected competition? Clearly !
