Athlon stands for AMD's Athlon processor series, (besides Phenom II series and Operton series for server market, etc.)
TM stands for registered trademark.
64 indicates that this type of CPU supports 64-bit operations, such as the operation of 64-bit operating system and 64-bit software (this depth is more complicated).
×2 means that this CPU has two physical cores.
the English string of dual core processor is directly translated as "dual-core chip processor".
52+ indicates the execution performance of the processor. Because this is a more traditional way of naming, you can understand that the real frequency of 52+ is 2.7G, but its execution efficiency is equivalent to 5.2G Pentium 4 dual-core (implying E52, but its actual performance is weaker. ) execution efficiency. The higher the value, the better the performance.
There is no problem with the picture. The dual-core processor is normal in the properties, but your U looks like the one made in the old 65nm process. If you want to be more detailed, use the software CPU-Z to test it. The latest process is 45nm.
please forgive me if the above explanation is insufficient.
