No windows.My understanding is that EU-count doesn't impact core video decoding functionality (which is done separately and doesn't use EUs). However scaling (and I believe de-interlacing?) use EUs - and in the bad old days of very limited GPU functionality on Intel SoCs you had compromised deinterlacing (i.e. motion adaptive only and no motion compensative) on very low power GPUs with a very small EU-count. However on current SoCs even the basic GPUs can offer decent deinterlacing.
Librelec / Intel VAAPI to be exact.
Can J4005 or J5005 decode same files/bitrate in the same quality? I was concerned because of the missing 6 EUs (UHD 600 vs UHD 605). I think that is waht Mount81 is also asking, if the GPU power doesn't concern the decoding.
I was about to buy an NUC with either of those SoCs...
Background: My Zbox ID 18 with Intel 1007U does not hardware decode h.265 or output UHD 4K, but as a raw LE Box did its work just fine, now i want to upgrade.
AFAIK the HEVC/h.265 and AVC/h.264 decode abilities are pretty similar across current models - though on some relatively recent, very low-power SoCs there have been question marks over high-bitrate, high-resolution, high-frame-rate decoding with single-channel lower-speed RAM (i.e. manufacturers recommended dual-channel configs) as you still have to pump a lot of pixels around (even if you aren't doing very much to them)?
Quote:When you talked about a low-power SoC, were you talking about the J4005 SoC?No - I was talking about quite a few generations before - Sandy Bridge / Ivy Bridge era.
Quote:Because i was about tpo use a 4GB DDR-400 DIMM (single channel) or would that be a problem (concerning upscaling etc) or did you talk about old generations like the Intel 1007U and older?
I think the Dual Channel stuff was an issue in Apollo Lake (or maybe one generation before) - I'm not across current issues.
