Even within a single app the results vary. So the question is why the other apps and plugins are not any better on the iMP. Neat also sizes GPU vs CPU performance and lets you select the optimum mix. This is Amdahl's Law: en./wiki/Amdahl%27s_law Even for perfectly-written software running on perfect hardware with zero bus or cache contention, multi-core scalability will fall off at higher core counts if the algorithm requires any synchronization. The 10-core iMP was nearly 2x faster than the 4-core iMac, which has a higher base clock speed. Neat is actually doing a pretty good job. What do you think: is this a lack of 'optimizing' on Neats side, or an OS/FinalCut issue? Who's in charge to make more use of all the 'power' in the beast? ok, 'twice as fast' is impressive,esp on longer projects - but with all the cores, and Xeons and wotnot… as a complete idiot on hardware, I would have expected … more. Software which harnesses those effectively is much faster.Īn extreme example is FCPX 10.4 export performance on 10-bit 4k HEVC: it is 32x slower than 8-bit, which indicates it's not using the AMD UVD/VCE transcoding hardware for 10-bit encoding. In recent years performance evaluation has become much more complex due to higher core-count CPUs, GPU and specialized accelerators like Quick Sync. I don't know why Portraiture wasn't much faster on the iMP. While effects often claim to be "GPU accelerated", both Flicker Free and Portraiture seem to be mostly CPU bound.

To de-flicker 10 sec of 4k H264/29.97 material this was:Īnother very compute-bound effect is Imagenomic Portraiture, which does skin smoothing.
Note the test evaluates all hyperthreaded virtual cores so this is 20 on the 10-core Xeon and 8 on the 4-core i7-7700K in the iMac.Ī similar slow-running compute-bound test is Digital Anarchy's Flicker Free.

IMac Pro: 10 CPU cores + Vega 64: 5.29 frames/secĢ017 iMac: 5 cores + Radeon Pro 580: 2.76 frames/sec This built-in Neat Video test evaluates all combinations of CPU cores and GPU to recommend the best configuration, and lists the frames/sec of each one.

I've tested this plus some other compute-intensive effects on my 10-core Vega 64 iMac Pro vs my top-spec 2017 iMac 2017. … pure academic interest, no Neat nor iMp here, but Q came up in some private discussion: Did anyone post numbers, how the famous 'CPU eater' NeatVideo compares btw a regular iMac vs.
