Overview of the AMD Athlon II X4 645
processor The processor was released in 2011 for motherboards with the latest Socket AM3 connector for that time. The model belongs to the high-performance CPU in the line of processors created for the AM3 platform, has 4 cores with a frequency of 3200 MHz and a heat dissipation of 95W, which will require an efficient cooling system (120W+). The AMD Athlon II X4 645 is made according to the 45nm technology standards and carries the Propus architecture. At the time of entering the market and the next 5-7 years, this processor was considered a worthy gaming option, offering good performance and good overclocking potential.
Currently, AMD Athlon II X4 645 combined with a fairly powerful video card (Radeon RX470, GeForce GTX960 and older), at least 8 gigabytes of RAM and low graphics settings is still able to provide minimum acceptable performance (25-30 frames) even in the most modern projects level of Red Dead Redemption 2. In older games like GTA V and Tomb Raider 2013, AMD Athlon II X4 645 will provide a comfortable number of frames per second at medium graphics settings. This CPU will provide comfortable work in Windows 7-10 operating systems, cope with office tasks, surf the Internet without any problems. nine0108
