Is my processor really what it should be?

So I was wondering, I just got Iqoo (a Vivo brand) phone and it is supposed to have processor Snapdragon 778g. And now when I go to Settings>About Phone, I see the correct processor name. Ok? But the issue is that when I check my hardware info through any other third party app (and believe me, I have tried multiple apps) then name of the processor that I see is completely different..... Is this normal? For phones to have a different processor?? I need some guidance, so please help. Also check the attached images...... The info on GPU is as follows- Vendor: Qualcomm Renderer: Adreno (TM) 642L Maximum Frequency: 550 MHz Gracias
