Got an i9 1TB SSD, 580X from the refurb store... First weird thing is I tested iMovie encoding. 4:30 video 1080p from H.264 footage - my i5 3.8 (running at 4.0GHz) 40G ram = 5:00, The new i9 8G ram running ~4.5GHz = 6:50 ... What??? Ran 4X - yep... The new one does Page out a few times where the 40G ram does not. Memory pressure is still less than 70% at all times. And I ran these tests on stock 2017 i5s and i7s in 2017 - was always very close with the i7 being slightly faster. The new i9 burns 2X the Watts - ramps fans to 2400 rpm at times and is almost 2 minutes slower... very unexpected - can't really buy more RAM just to try in it! The i5 ramps fans to maybe 1800 half way through. Fan much quieter than 2400 on the i9. Would 16 or 32G of RAM solve this or??
