[citation][nom]tabletman2[/nom]A lot of people here are misinformed about the capabilities of HD4000. Please check the review, benchmark or passmark before commenting remark such as GPU in W500 being faster. As far top of AMD GPU being faster, what else do you expect comparing top of anything against entry level part? But even mid range of AMD APU is not faster than HD4000. For details, check passmark. Do not mistake HD4000 for HD3000.[/citation]
Except given that the CPU in this thing is an i5 (decent--definitely not low-end), so why would someone hypothetically substitute it with a low-end APU? If you wanted to just match CPUs based on TDP, the i5-3317U is a 17w CPU. The best match would be the A6-4455M (it's a 17w TDP chip) which has the HD7500G, which pretty much matches HD4000 in performance--the HD4K isn't impressive in comparison). That's basically the lowest-performing GPU in AMDs mobile APU lineup, but better GPUs in the higher TDP APUs. If you want to make a comparison, at least use similarly-spec'd components. Don't just arbitrarily pick low-end if it is nowhere near the performance of the thing you're comparing it to.
