Radeon R5 M330  vs GeForce 920M 

if it just for video, an integrated graphic will do the job smoothly..4gb will be good enough

Hi, I want to buy a new laptop and wanted to know if the laptop with below configuration can play X265 1080p or 720p videos smoothly. Here are the details : Specifications of "Lenovo G40-45 (Notebook) (APU Quad Core A8/ 8GB/ 1TB/ Free DOS/ 2GB Graph) (80E10088IN) (14 inch, Black)" ************************************************************ Display : Resolution 1366 x 768 pixels Screen Size 14 inch Screen Type HD TN GL Flat eDP Display Storage : HDD Capacity 1 TB RPM 5400 General : Brand LENOVO Part Number 80E10088IN Model ID G40-45 Color Black Lifestyle Everyday Use Memory : Expandable Memory Upto 16 GB RAM Frequency 1600 MHz System Memory 8 GB DDR3 Memory Slots 1 Slot Machine Dimensions : Weight 2.5 kg Dimension 384 x 265 x 25 mm Color Black Graphics : Dedicated Graphics Memory Capacity 2 GB Graphic Processor ATI EXO PRO R5 M330 Dedicated Graphics Memory Type DDR3 Audio : Sound 2 x 1.5 W Speakers Speakers Yes Platform : Operating System Free DOS OS Architecture 64 bit Processor : Brand AMD Cache 2 MB Variant A8-6410 Clock Speed 2.0 GHz with Turbo Boost Upto 2.4 GHz Processor APU Quad Core A8 ************************************************************ Or Can a system with 4gb RAM or more, Intel HD graphics play X265 1080p or 720p videos smoothly? Do X265 1080p or 720p videos still need a NVIDIA graphics card? If so, what size of NVIDIA Graphic card is required like 512mb, 1gb, 2gb, etc? Thanks.
