Testing the 2019 Mac Pro and Pro Display XDR

Lloyd Chambers:

Thus my updated advice is to buy ONLY a 16-core (or 24/28 core if warranted). An 8-core or 12-core Mac Pro is marginal in terms of CPU performance relative to the 2019 iMac 5K.

My testing shows that for single-threaded stuff, a CPU core in the 16-core 2019 Mac Pro is up to 30% slower per core than the 2019 iMac 5K.


I’m an app developer/designer and recently got a new mac pro for my business and wanted to see how it stacked up with my other machines. The results are interesting; the Mac Pro does not do so hot when making clean compiles, but does deliver consistently faster incremental builds.


It seems the best bang for your buck right now when it comes to compiling projects is the Mac mini. I’m certainly disappointed in the Mac Pro results, especially since it seems that Xcode completely pegs all the 16 cores during a compile, but even at 3.2GHz fails to outperform a 3.0 GHZ i5 with 6 cores.

Note that these tests were performed with Xcode 10.3 rather than Xcode 11.

Juan Salvo:

For folks considering the Apple Pro XDR monitor as a reference screen. Here is it, side by side with a couple of actual reference monitors.


Like the 310K the XDR uses local dimming zones. 576 of them to be exact. So a grid of 32x18. Now there’s a lot of factors to how effectively they zone. But 576 is not very many zones and the result is that you can clearly see the haloing.


Update (2020-01-07): Mike Rundle:

At the XDR display introduction event, Apple did go out of their way to compare it to reference monitors that cost $30-50K, so this is a fair comparison.

Vitaly Ishkulov:

Apple’s 1:1,000,000 contrast ratio on the new Pro Display XDR. It’s just a white line on a black canvas. Also see the glow around the perimeter of the canvas.

Update (2020-01-10): Quinn Nelson:

I’ve only been using the ProDisplay XDR for a day, but I’m getting pretty extreme color and light roll-off in all four corners of the display. Almost like vignetting. When I readjust my head it’s fine, but viewing angles on this monitor are not very good which is disappointing.

I will say however that even though I didn’t opt for the +$1,000 matte option, this “glossy” option is very much not glossy. The glare is unbelievably low and makes my iMac Pro look like a mirror. I hope Apple brings this across the entire Mac lineup. It’s awesome.

Quinn Nelson:

I, for one, am glad that Apple doesn’t include the Pro Stand in the price of the ProDisplay XDR (as many have said Apple should have done) because I don’t think it’s actually a very great stand and anybody buying the monitor should VESA mount it instead.

Quinn Nelson:

Tilt doesn’t lock to perfect 180 deg and the tilt radius is not even. Tilts way more to the left than to the right. No height adjustability in vertical position sucks. No axis control.
