Best CPU's 2017

Intel have officially announced the seventh-generation of Core processors, also known under the name of Kaby Lake, designed for desktop computers. Today’s new generation is opened by two models of quad core, Core i7-7700K and Core i5-7600K. Intel, however is increasing its range, for example, Core i7-7700, Core i7-7700T, Core i5-7600K, Core i5-7600, Core i5-7600T or Core i3-7350K.

The seventh generation, new processor platform debutes with the logic of the 200 series. Motherboards with Z270, Q270, Q250, H270 B250 are on the market. It is worth noticing that the processors Kaby Lake can also work on motherboards with the logic of the 100 series, although appropriate UEFI update is needed.

 

Seventh generation core processors use the improved architecture of the sixth generation systems (Skylake). The new generation is produced in lithography, which Intel defines as 14 nm +. The new processors have higher clockspeeds than their sixth generation counterparts (Skylake), but Intel has kept wholesale prices unchanged.

The most powerful representative of the seventh-generation Core is Core i7-7700K, acting base frequency 4. 2 GHz which can be increased to 4. 5 GHz with Turbo Boost technology. This model supports HyperThreading. The layout is equipped with 8 MB cache, so with an unlocked multiplier should ideally work on overclocked platforms.

 

The second in the order is Core i7-7700, whose predecessor differs not only in that it has a locked multiplier it also works with the clock 3. 6 GHz, up to 4. 2 GHz with Turbo Boost. The same series have also a model with reduced power consumption which is Core i7-7700T, operating at frequency of 2. 9GHz up to 3. 8 GHz with Turbo Boost technology. Both recent models have the same third-level cache.
 

Intel's offer grows with new Core i5 series processors. Here we have a similar version set, with Core i7. This processor has a 6 MB cache third level and works with the base frequency 3. 8 GHz and with Turbo Boost technology can grow to 4. 2 GHz. It should be noted that the Core i5-7600K does not support the HyperThreading and is a quad-core. This model has a Core i5-7600, layout with a locked multiplier, the same memory capacity L3, but smaller clocks-base 3. 5 GHz Turbo Boost up to 4. 1 GHz. Next in order, Intel Core i5-7500, which has even smaller clockspeeds to its predecessors.

This model works with the base frequency 3. 4 GHz, and its maximum clock Turbo Boost is 3. 8 GHz. We also have energy-efficient models, Core i5-7600T and Core i5-7500T. Thermal design power of both these processors is 35W. The first of these works with the clock 2. 8 GHz and Turbo Boost up to 3. 7 GHz, and the second 2. 7 GHz Turbo Boost up to 3.3 GHz.

AMD after four years of work on the development of the Zen chip architecture , now intends to utilise the benefits form this development. Mark Papermaster from AMD while talking with representatives of PCWorld at CES 2017 confirmed that Zen architecture provided for a four-year life cycle, but he would unfortunately not reveal the details.

Intel's architecture policy, Tick-Tock, as a two-year cycle, it seems to be alreadybe the song of the past, AMD is planning a four-year cycle for Zen architecture and do not intend to copy Tick-Tock policy. Instead, as Papermaster said, Zen is supposed to have only that part of the cycle, which Intel defines as in Tock.
 

Intel policy (Tick-Tock) was a two-year development cycle for the processors. In the first year the new architecture (Tock)was created, and in the second , it moved to a newer manufacturing process (Tick). With the advent of Core seventh generation  processors, known as Kaby Lake, Intel broke the existing two-stage cycle and added third stage, which is a copy of the stage (Tick). Kaby Lake processors do not make use of the new architecture. Instead, Intel decided to move the 14 nanometer Skylake architecture  to a enhanced process, which the company describes as "14 nm +".

AMD Ryzen have unlocked multipliers, which has facilitated their overclocking. Among the expected models there are a few marked with the letter "X", R7-1800X, R7, R5 magnifications, R5-1400X and R3-1200X. These systems, according to recent reports have XFR technology (eXtended Frequency Range), so the solution is running like Turbo to increase the CPU clock even more, providing the temperature conditions allow it.

AMD Ryzen R7-1800X can work with the base clock of 3. 6 GHz and up to a turbo Core of 4 GHz. Frequencies of the XFR can exceed the 4 GHz barrier. R7-1700X XFR clocks will be above the 3. 8 GHz, R7-1600X above 3. 7 GHz, R5-1600X above 3. 9 GHz, and R3-1200X above 3. 8 GHz. From unofficial sources we learn that there is no maximum clock set in the specifications. This does not mean, of course, that some processors have exceeded locks for some frequencies.
