I wanted a cheap laptop to do some light gaming and to replace my 9-year old Dell Inspiron 600m (still running strong...just slow). I found this Lenovo Ideapad Z575 with AMD A6 proc + Radeon 6650M discreet video card for $550.
It's a nice laptop: good build quality, good specs, good price.
I started to dig a little deeper on the specs of the discreet Radeon 6650M. I used GPUZ and Sapphire TriXX to see the exact specs. Both showed that this discreet video card is a Whistler, but the memory bandwidth is only 32-bit instead of 128-bit and it contains only 2 ROP units instead of the 8 as stated in Wikipedia.
Is it possible that these tools read the specs wrong? Is it possible that the Radeon card shut off most of the processes to save power, and will turn them back on during high demand?
Another thing, GPUZ and TriXX both reported the 6650M to have 800 shader units when in reality it should have only 480.
I appreciate it if anyone can shed some light into this situation.
