caqde :
They are around the same performance the HD8750m is slightly faster in most cases but will likely use more power (so if you plan on gaming while on battery......). The other factor is that the 920m should generate less heat. Besides those two there is no performance reason to justify going with a notebook that has the 920m over the 8750m.
Also as long as it can take the newest drivers it is a DX12 part being that it is based on AMD's GCN architecture. I do believe acer notebooks allow you to install AMD's reference drivers so this shouldn't be a problem.
So what should go for?
I understood that go for GT 920m for less heat and battery
Well I'm looking for the direct X 12 supported once and Battery life doesn't matter a lot for me but
I want the best performance for gaming I know both aren't good for gaming but looking for moderate gaming performance also power point is okay at Radeon once but what I'm afraid of is heating point
Cause I used a laptop that overheats like a hell so my question is Will it bypass 48 C temperature with this Radeon GPU?
At end I may go for Radeon once if below are on it: (What I want to know if the features below are on it or not this is questions)
Heating not bypass 49 C or 50 C (while gaming)
Direct X 12 well supported
A better performance even by 0.5% and well supported driver updates (at gaming)
Reasons may I go for GT 920m:
Newer
Direct X 12 well supported
Less heat ( I believe it won't bypass 49 or 50 C temperature)
Well supported driver updates
Reasons may I go for Radeon once:
All I listed above but one more thing: The price
And at end my question is:
Is Acer good brand for laptops?
And does it provide well supported updates?
Does the Radeon GPU above gets good driver updates like GT 920m and support direct X 12 well like GT 920m?
And at end should I go for Acer once and save a penny or worth the extra price and get the Dell once?
