I have a Lenovo Thinkpad edge e535 and I want to upgrade my CPU of my laptop. Its an AMD A4-4300m and I checked the socket type and found out I can upgrade to the A10-4600m. However the Laptop has integrated graphics. I opened the laptop once to see whats inside and i saw two chips under the heat sink, I know one is the CPU inside the socket but i dont know what the other one is. Is it the data hub? The GPU? Im wondering this because the description of the CPU says that it comes with the Radeon HD 7670g. If i upgrade will i get this new graphics card? Is the chip next to the CPU the hub or the GPU?
