Good processor
6 September 2018 
Bought it for work in Visual Studio for DirectX projects and basic programming and learning. Paired with an Asus X299 WS motherboard and Fractal Design Celsius S24 water cooling, the frequencies automatically set to 4.6-4.7 across all cores with 1.2 voltage in the EZ Tuning Wizard utility. In the 3DMark TimeSpy 1.0 basic test, the processor scores more than 10,000 points, and in the Intel Extreme Tuning Utility test, it shows about 3,000 points.
+ 4-channel memory
+ Good performance in single-threaded applications
+ Decent performance in multi-threaded applications
+ Easily reaches 4.6-4.7 GHz on all cores at auto voltage or at 1.2V
+ Good compatibility with various memory modules
- Thermal paste under the cover
- Relatively high price for 8 cores
Garna of a robotic horse
24 December 2023 
The Witcher 3 and Cyberpunk2077 run on ultra without any glitches. Video RTX 2070S. All tests were carried out without overclocking.
+ There is an overclocking capability;
+ There have never been any complaints about the operation.

Old doesn't mean bad

Basin Falls processors with the number of physical cores from six, like the Core i7-7800X, to eighteen, unlike the quad-core ones, are not built on the latest Kaby Lake-X architecture, but on the slightly older Skylake-X. The main difference for the worse is a lower frequency (even in the case of manual overclocking) caused by the 14+ manufacturing process instead of the more advanced 14++ nanometers. However, for CPUs with such numerous cores and threads, several hundred megahertz do not make a difference.

The power of two graphics cards

In our opinion, the Core i7-7800X is the perfect foundation for an uncompromising gaming PC with two flagship GeForce GTX 1080 or 1080 Ti graphics cards. There are two reasons for this. Firstly, eight threads are no longer enough to unlock the potential of two graphics accelerators. Secondly, LGA1151 processors allow you to connect video cards only in PCIe x8 + x8 half-bandwidth mode. Whereas the LGA2066 platform removes this limitation.

Shock five-year plan

As a result, the Core i7-7800X is not a processor for the first time, and not for growth, but to be used here and now. As they say, assembled, works and do not think about upgrading. A computer with such a processor and two GTX 1080/1080Ti is guaranteed to be able to run all the games on ultra-graphics settings in 4K resolution for another three or four, or even five years.
