Very pleased with this purchase, will recommend it to everyone!

I experimented with a heat pack using turbo bust 2. A slight increase in performance was achieved due to a noticeably greater warm-up of the processor and an increase in the noise level. Roughly equivalent to using the I7-8700K. I left the default mode, but I mean turbo bust 2 in case of critical situations in terms of performance.

It seemed interesting that the behavior of the I7-8700 under stress tests is significantly different from the behavior of the I7-3930K. In the case of, for example, Prime95, the temperature of I7-3930K increases monotonically with an increase in the number of streams, and the temperature of I7-8700 has a very pronounced maximum at 2 streams and decreases with an increase in their number. At the same time, according to HWiNFO64, the processor consumption reached a maximum of 65 watts with 2 threads and then did not change.
The I7-8700 behaves similarly when using 7Z, but the maximum temperature is reached at 4-6 flows and is somewhat less pronounced.

Pros

The task was to create a lightweight graphics station for home use. I was looking for a compromise between power, system unit size and noise under load. As a basis, I took the I7-8700 with a 65 watt thermal package. Acceleration was not expected. The choice of Intel was due, among other things, to high performance in low-threaded applications. Compared with an old computer on a non-overclocked I7-3930K. The new machine turned out to be about one and a half times faster in all tasks. In some cases, the advantage was about 80% due to the use of AVX. All this while reducing energy consumption by 2-2.5 times. The result is a cool and almost silent machine in a mini ITX case with abundant wall perforations (no noise protection).
