What is the laptop EXACT model?
Don't worry about the 6470 vs 7400 thing...they are basically the same card..Rebranded.
My laptop is a VAIO core i3 intel inside (product name:VPCSB4L1E).
It has intel family graphic card and radeon 6470M (according to radeon setting, i'm using radeon graphic card as primary graphic card).
runs on win 7 64 bit ( may be with Home Premium).
Yeah i have read that somewhere too but i cannot play anything with the presence of 7400M( insane amount of lagging, and the graphic looked as if anti-aliasing was rendered off, the color was somewhat changed too, like fire would normally be orange but was changed to white), change it back to 6470M and everything works fine again.
Your laptop is equipped with switchable graphics. In order to update the AMD driver, the Intel graphics should be the current version. Go to this Intel link, and use the Intel Driver Update Utility to find the latest graphics driver for your laptop. Download and save it to your desktop.
Download these AMD drivers to your desktop.
For Windows 8.1 or Windows 7
Now delete the Intel drivers from your computer using 'uninstall a program' in the computer control panel.
Uninstall the AMD drivers from your computer using the 'uninstall a program' in the computer control panel.
NOTICE IMPORTANT AMD DRIVER UNINSTALL:******
******Computers with Intel processors select 'express' uninstall all AMD software including the install manager.
******Computers with AMD processors custom uninstall the AMD graphics driver and Catalyst Control Panel only.
Note: All anti-malware/anti-virus/anti-anything should be disabled during driver installation.
Install the Intel drivers...reboot
Install the AMD drivers...reboot
