yo guys johnathan here 18 cores an imac are probably two things you would never expect to say in the same sentence but with the iMac Pro that is a thing this is the fastest I Mac Pro you can buy 18 cores AMD Vega 64 graphics 128 gigabytes of RAM and a 4 terabyte SSD so I've been a tenant in the last couple days with this monster of an iMac and I really wanted to focus on performance for reference I'll be showcasing it against a ten core Vega 64 iMac pro as well as an 8 core Vega 56 model so jump it into the obligatory geek bench for score because honestly it's just kind of fun to see where these 18 cores stacked up this did not disappoint with a multi-core score of over 48,000 you now what was a little surprising but also positive is you don't lose that much in terms of the single core score compared to the ten core an anchor model especially considered at the base clock on this is 2.3 gigahertz also what was kind of interesting for me this is the first time I've got a chance to stack up the one terabyte 2 terabyte and 4 terabyte SSD configurations the bad news is the 4 terabyte really isn't much faster than the 2 terabyte or 1 terabyte for the matter but on the flip side of that the good news is no matter what route you go you're gonna get pretty much the same performance across the board now as far as how that power translates in the performance the first thing I did was take 8 K raw footage it was about a hundred gigabytes or just over 26 minutes of footage and transcode that into 8k ProRes to do this I use red cine X program which really puts those cores to work like it was maxing them out with the 18 cores especially when you factor in multiple threads scene 36 instances run at the same time is kind of a beautiful thing as far as what those cores translated to the 18 core iMac pro took a little over 39 minutes the 10 core was 46 minutes and the a core iMac pro did the job in just about 51 minutes now your initial reaction might be 5 6 minutes that's not that big of a deal but where it counts is is when you do that multiple times per day then multiply that every day for a week for a year that's where that really makes a difference so next up is cinema 4d this is a custom scene that was tweaked by my buddy Matt workman essentially it is only using the CPU to render out this scene so it's a great way to showcase the performance between the processors the 18 core rendered everything out in four minutes flat a 10 core was 4 minutes and 48 seconds while the 8 core finished everything up in 6 minutes and 4 seconds again much like the red raw transcoding these numbers and this time saved on a small scale might not seem like the biggest deal but over time it definitely adds up from there jumping over to Final Cut Pro 10 red raw the iMac Pro and Final Cut Pro have been amazing to give you a little rundown on this project I have a que red raw footage at a 12 to 1 compression this was shot in Reds IPP two logs have a lot applied a few different layers of color correction and then at back and rendering off to really put these iMac pros to work so the raw timeline which is unrendered is about three minutes and taking that next corner to a pro rs-422 file the 18 core I Mac Pro did that in 5 minutes and 51 seconds to the 10 core 6 minutes and 34 seconds in the 8 core 7 minutes and 22 seconds even though the 10 core iMac pro still has the fastest single to add a turbo clock speed in this case you can see in terms of final cut the extra cores do actually make a difference in my continued search of programs that really take advantage of the processing power though ScreenFlow 7 actually takes really big advantage of all those cores with the iMac Pro what it did was take a 5k screen recorder and had a three-minute project and an export of that into 4k h.264 footage the 18 core I Mac Pro did that in 1 minute 48 seconds the 10 core 2 minutes and 24 seconds and lastly the a core iMac pro 2 minutes and 46 seconds now I did mess a little bit with Adobe Media encoder took a 6,500 footages about 10 minutes of 4k video I try to transcode that into 4 to 2 ProRes the 18 Court did that in 6 minutes 54 seconds the 8 core was 8 minutes and 36 seconds but for some reason the 10 core was actually slower than the 8 core at 10 minutes and 8 seconds but from what I could tell Adobe Media encoder really wasn't taking advantage of all that hardware I'm gonna do a little more research and a little more investigating but I did want to share those preliminary Adobe results first now plot twist those motion graphic benchmarks featured throughout this video work created natural natural I thought it would make sense to render them out on these Mac Pro's so for total of six independent renders the 18 core I Mac Pro finished everything up in 10 minutes and 36 seconds the 10 core was actually the fastest here at 9 minutes and 43 seconds and in the 8 core I Mac Pro did the job in 12 minutes and 19 seconds so these numbers kind of tell me a couple different things one the clock speed on the tank or a Mac Pro here in this case definitely makes difference in two based off those comparisons against Adobe Media encoder Adobe is clearly not taking full advantage of the hardware on these iMac pros honestly I still think the 10 core I'm a pro is the best value in terms of bang for your buck with performance but if you need that sheer processing power those 18 cores really come in handy now if you line up the 8 the 10 and 18 core in my case the only one I haven't checked out yet is the 14 core in terms of price and what you gain performance wise it's a pretty even jump so if you transcode a ton on a day-to-day basis or potentially use really CPU intensive programs like cinema 4d that's maybe where those extra cores come into play but if you're asking me I still think again the best bang for your buck is the 10 core iMac Pro but nonetheless the 18 coleye Mac Pro is a super solid performer it is very very powerful hopefully enjoy this video if you did and you or feel like being awesome make sure you guys smash that like button this is Jonathan and I will catch you guys later
