I should of course remember to clarify this was using a Brazos/Bobcat CPU with the discrete card. The point being Brazos/Bobcat can't pull more then the IGP anyway.
The reason for Brazos fairly powerful IGP is hardware accelerated media playback, to compensate for the relatively weak CPU.
the first brazos e350 was excellent product because its igpu was powerful enough to play media content thus it had a role to play
a cheap pc for media contest and web browsing and yes for light work loads in offices
what followed e350 was disappointing or not followed
e450 had no real reason of existing
amp in this category should have aimed to increase the cpu perfomance in each generation keeping the tdp the same
then they could give a motivation to upgrade
but amp went lower tdp and more igpu !?!??!!?
thus destroying the series and the platform
they could made some variants
1. more sata ports so you make a nas storage they could in this variation enable ecc support and have it more expensive
2. more cores a 4 core design promised but never delivered with igp or without.
3. a variation for 16 pci lanes so you can put a good graphic card and use it with software that will run in the card and not rely on the cpu.
amp has to much gpu to cpu ratio which is bad
because a favor with cpu would mean it will make more sense when you install a dgpu because there will be nto cpu limited thus making the dgpu a joke rather than option
