I'm sharing my journey from my experience in evaluating if I should change from my current 4.1 mac pro to the 6.1 mac pro. I hope this test will help other people in the same situation if you are considering upgrading. I managed to get hold of a new Mac Pro which I used for over 2-3 weeks. Background : I started off as a photographer, but over the last couple of years I have been taking on more videography projects. Typically my videos are under 10 minutes with titles, text and simple transitions. Currently I happen to be working on a major project that requires producing videos of 30 to 40 minutes in length, with lots of multi cam and compound clips. I edit in FCPX. For photography I do corporate and wedding shoots. Editing corporate shoot isn't hard as the final number of images are usually under 100. I edit wedding shoots on Lightroom, which usually number around 1600 shots. old Mac Pro - OMP 8 X 3.33ghz processor 28gb of RAM GTX 670 2 X 120gb raid0 SSD vertex 2 boot drive. new Mac Pro - NMP 6 X 3.5ghz processor 2 X D500 1 TB apple internal SSD Test from Reboot, one after another. I used BruceX as a base so if you want to you can do the test on your own system for comparison. Geekbench OMP : 19864 NMP : 20010 BruceX - 5K export OMP : 1 minute 40 seconds NMP : 26 seconds (384% faster) BruceX seems to test more for GPU accelerated effects, so the following are variations to test on CPU crunching. Taking the 5k master file export from BruceX, duplicate it 20 times and export as 5k master file (if not the clip exports too fast to react to), I shall call this clip BruceX20 OMP : 10.3 seconds NMP : 7.3 seconds (41% faster) BruceX20 Compressor export (No additional Instances) Video Sharing Services 1080p (H.264) OMP : 4 minutes 22 seconds NMP : 3 minutes 50 seconds (14% faster) MPEG Program Stream 1080p OMP : 2 minutes 7 seconds NMP : 1 minutes 37 seconds (31% faster) BruceX20 Handbreak export Normal : H.264 OMP : 1 minute 32 seconds NMP : 1 minutes 15 seconds (26% faster) Normal : MPEG-4 OMP : 1 minute 44 seconds NMP : 1 minute 16 seconds (36% faster) For photo Processing I'll grab files from http://www.rawsamples.ch/index.php/en/canon (so you can do the same if you want to), I'll download the first 5 files and duplicate them 3 times. Auto everything, Auto lens correction Export to Jpg, Quality 10 (15 files) OMP : 21 seconds NMP : 20 seconds (5% faster) Conclusion ====== The difference in performance seems to be about 30% faster, but it is from a clean boot. My experience tells me other wise; Once you start running other program or doing work at the same time, the difference feels smaller, around the range of 10% to 20%. The extra cores on the oMP seems to help with spreading out the workload. This was how I would describe the REAL LIFE experience. I was working late into the night, both computers on at the same time, doing some work and surfing at the same time. Once it was time to convert the master file to h.264, I ran it on both computers, I can't remember how long it took, but I remember the difference between the 2 computers was less then 2-3 minutes. Thas was for the conversion of a 30 minute master file. If you happen to own a souped up Old Mac Pro, It think you need to go beyond the 6 core model to make it worth your money. I mean, 6k for a real world 20% improvement seems to be very bad bang for the buck. I guess a chip upgrade the Old Mac Pro to the 3.0ghz 12 core would probably get me close to that performance for just 10% of the cost. With upgraded video cards, you might approach, the 6-8 core performance of the New Mac Pro. Hope this comparison will come in useful for people contemplating upgrading.
