WWDC 2018 takes place June 4 to June 8 in San Jose, California.
New Mac Pro: Simultaneous Real-Time 4K Effect Rendering, +900MB/s Read/Write
FCP.co posted a 24-hour hands on with the new Mac Pro. They found read speeds of 880MB/s from the Mac Pro's solid state storage, with impressive write numbers of 985.5MB/s. Further, the team discovered that new machine could post full 4K video with multiple color corrections, effects and transitions playing back all in real time.
Macworld saw even more impressive SSD performance, with Black Magic reporting 952.8MB/s writes and 920.5MB/s reads. Black Magic's speed test app reports that the new Mac Pro can easily handle all video formats it currently tracks, with FCP.co adding that its Mac Pro was able to play back 16 simultaneous streams of 4K video.
On overall performance, FCP.co writes:
I can quite honestly say that, despite working with these huge file sizes and frame sizes, the editing experience has been silky smooth. Skimming, playback, shuttling, jogging and trimming are all responsive. In fact, editing 4K on the Mac Pro feels like editing HD on my current MacBook Pro - except I can see large numbers for the frame sizes where normally I’d expect to see the reassuringly familiar "1920x1080".They went on to push the machine by adding real-time effects to a 4K stream to see the breaking point.
I started slowly, adding a simple Dry Heat look. That played back in real time, no dropped frames. How about a Gaussian Blur? That’s usually a bit more intensive, especially with the huge numbers of pixels we're dealing with here. No dropped frames. Nice. How about a Gaussian blur with a Bleach Bypass look? Still in real time… ok, let’s get serious…
And so it went on… Multiple colour corrections, effects, transitions. This thing keeps playing back! In fact at one point I took a RED RAW 4K clip into a 4K project and just started working through the list of video effects (many of which are 4K ready). Watch the result for yourself.
Back in September, GeekBench scores for the new 8-core 3.0Ghz Mac Pro appeared, giving the unit a single- and multi-core scores of 3349 and 24429. Now, on production hardware, Macworld got scores of 3599 and 25997, a modest improvement.
Both Macworld and FCP.co mentioned a gentle but notable current of warm air rising from the machine, but that the Mac Pro's fan was barely noticeable. If something is placed on top of the machine's vent hole, like a book, the Mac Pro will shut itself off before any damage can occur.
The new Mac Pro is available for order now, but shipments are not expected until well into the new year. An Apple spokesperson said yesterday that "demand for the all new Mac Pro is great and it will take time before supply catches up with demand".
