Not having read HP specs, it seems the intel is much heavier from the performance per pound bars. If so, can only be explained by bigger batteries methinks.
A choice between ~30% better cpu vs kick ass battery life (no gpu discrete), lighter & 200% better graphics. I know which I & I suspect most would prefer.
Integrated usb 3 is a big plus w/ amd chipsets too.
Assuming 500 vs 630 pounds is right - some say its a pittance over life of the unit, 2 years is not uncommon for these - when you consider the future worth of that money, its a big chunk of your next , way cheaper & better mobile device.
Due to a shortage & huge demand, amd prices are at a premium. expect lower once sorted.
Not sure what ram used but NB - going from ~1333 ram to ~1600 ddr3 pays huge graphics dividends. If you add a similar graphics radeon discrete GPU, expect a 75% graphics boost on amd APUs. There is no dual gpu mode for intel.
intels mantra about grunt cpus is getting as tired as muscle cars. Vast majority could do w/ a 10 yr old cpu for what they do - not so w/ graphics & power consumption tho. We are at a watershed where AMD/ATI can make intel dance to their tune cos no way intel can compete w/ ati graphics for years.
If, as you say, you are smart enough to need cpu grunt on a mobile, u should be smart enough to offload it to a server on the cloud or at the office.
AMD may be a bit slower on cpu, but intel grinds to a halt on some apps on its igp. I know which would annoy me most.
Wasnt there an obscure scandal about intels igp cheating at graphics conversions - they are lossy & crappy?
