Ive tried extensively with regular and m16, the m16 sheds about 15-20% of render time, getting the dual xeon slightly closer to the i7. Another oddity, i tried displacement, with an imported obj, the i7 took 4 minutes to render the scene, the -m16 xeon took 12 (twelve) minutes, and the regular (32 threads) took a relaxed 15 minutes approach. I thought maybe the imported obj is difficult for a xeon processor, so i did a test with a built in nuke sphere, displaced it a bit with local noise node, and the i7 took 8 minutes and the -m16 xeon a leisurely 19 minutes. so, it seems to me that nuke is not liking xeon processors. thats a big shame, because i need these for 3d rendering...:-(
