wait, by PCU hardware, does this mean video card?
OT: Yung R7 ba na sinuggest mo pala in the other thread, would that be able to handle 4k?
Yup. AMD Radeon R5, R7 and R9 graphics support 4K, upto 4:4:4 - 30p over HDMI.
Nvidia Geforce 700 and 800 series desktop products also support 4K, upto 4:2:0 - 60p over HDMI.
Higher quality can be achieved with both AMD and Nvidia over Displayport.
What is scarier is the processing required for 4K formats. Until H.265 becomes hardware-accelerated, it can be very demanding. This is where we badly need OpenCL. CPU-only software decode of Main 10 @ Level 5.1 Main Tier is already enough to saturate 8-core workstation processors. This for current-day displays (4k/60p 30-bit).
I can only dream about what's required for Main 16 @ Level 6.2 High Tier (6.4Gbps HEVC). This format is for 8k/120p 48-bit.
While we are stuck with H.264, Intel Quick Sync is the most convenient choice for 4K decode (followed by Nvidia PureVideo).
