windows 10 systeminfo show :AMD Athlon(tm) X4 760K Quad Core Processor，3800 Mhz，2 core，4 logic processor is it true?
Yes and no. Your CPU has 2 modules which each contain 2 integer cores and a single FPU (although that FPU is 2 FMA units it only counts as one FPU) those integer cores share a front and back end on the module.
Windows will identify the CPU as having 2 physical cores and 4 logical cores to avoid over tasking the FPUs, all the Bulldozer iterations behave in this way and are seen as hyperthreaded dual cores by the OS (or triple cores or quads depending on the model)
So in short while your CPU does have 4 physical integer cores their shared nature means they're not seen as 4 separate cores by your OS
