Careful... I know I will get some nodding heads from this, but hear me out. I appreciate their tireless efforts in journalistic integrity and brand neutrality. Commendable as they are, GamersNexus is not—bold statement, but repeat—not the ultimate authority in technical know-how and experimental accuracy. Take this example from recent memory. With one of Adobe’s major spring 2018 updates, Premiere brought Intel hardware video encoding acceleration support to the table. Here, GamersNexus made a big mistake in concluding this was a unilateral step forward. They benchmarked the performance of Intel 8th Gen with this enabled compared to AMD Ryzen 2000 using the default software encoder. Fair? Hardly so. That hardware acceleration happens to be Quick Sync Video (QSV) which is still highly debated for its fidelity in streaming and podcasting circles. If they were on top of things, they should have gone back and also used Voukoder in Premiere enabling NVENC for the GTX 10 series graphics card they use in their test setup to provide another option in their test results. Arguably, QSV, even in its most recent revision, still is a far cry in video quality from a software encoder like the videophile standby x264. This example also bears some relevance here. I wonder if QSV is being used here in the streaming test as well. If so, that would account for the major difference we are seeing in the encoding workload power draw between AMD and Intel in the GamersNexus result set.
