Review on 🚀 Experience Power and Speed with AMD Ryzen 7 1700X Processor by Micha Micha ᠌

Regarding games, in my opinion, the lower average fps is balanced by much more stable minimum fps: where Intel dances up and down, AMD is more even, without jumps and microfreezes. In literally everything else, the 7700k has no chance, both in terms of pure performance and the cost of a processor + motherboard + cooler kit. R7 Ryzen is designed as two CCXs - in simple terms, the processor behaves like two quad-cores with eight threads each. These two complexes are connected by Infinity Fabric - a 22 GB/s communication backbone. Inside the complex, the cores communicate through the L3 cache, 175 GB / s wide. Thus, cores 0-3 or 4-7 have no problems communicating with each other, but when core 3 requests data from core 4, this happens over a much slower Infinity Fabric. The Windows 10 scheduler does not recognize this problem and runs processes and their data from thread to thread, which obviously creates a performance drop when transferring them from one CCX to another. AMD comrades said that there is no bug in Windows, everything works as intended, i. E. don't wait for a fix. You can manually (using Process Lasso) force the process to use only one CCX, while there is no performance drop, but the process does not see half the processor either. In Linux, a similar problem was solved very quickly and the scheduler there is aware of the characteristics of the processor. By the way, on the approach of R5 and R3 (6c/12t, 4c/8t and 4c/4t models), they still have the same two CCXs (and not one 4c/8t from R7, as common sense would suggest). So this is a feature of architecture and there is no getting away from it. The difference between 1700 and 1800\1800x is not overclocking potential, but voltage. The 1800x will overclock 300 MHz more than most, but at a much lower voltage, resulting in lower power consumption and heat. The price in 2022 is simply terrible. I ordered from Germany along with the Asus B350M-A motherboard, 27000 came out with delivery, here one processor costs 26600.
