Re: My review of HP G6-2005AX laptop having AMD A8-4500M Trinity processor..
Hey akash cud u pls let me know how much the total graphics(7670m+7640m)
add up to? 1gb or 1.5 gb...pls discuss
I'll start off with how Crossfire works in desktops.
I have HD 6950 2GB. If I will buy another HD 6950 2GB and Crossfire them, I'll still have 2GB memory. Memory does NOT double or add up.
I have HD 6950 2GB. If I will buy a HD 6950 1GB and Crossfire it with the 2GB HD 6950 I have, I will have 1GB memory.
If HD 7640G is set to have 512MB shared memory from BIOS and HD 7670M 1GB is Crossfired with it, the combination will have 512MB memory.

Now you should NOT care about graphics memory in current day laptops with 1366x768 resolution.... 512MB is MORE THAN ENOUGH.
Graphics memory will matter if you are playing on 1920x1080. 512 MB is more than enough.
Laptop GPUs like GT 540M/GT 630M, HD 6770M and GT 640M are not even fast enough to make use of 512 MB VRAM. Nor is the reoslution 1366x768 high enough where high VRAM makes a difference.
