12 Core Mac Pro 5,1 - vs - M1 Mini with NAS


Logically, I know the answer… But logic and me - well - it’s complicated.

I have a 2010 Mac Pro 5,1 Quad Core 2.8Ghz with stock GPU, 8GB RAM, a 512GB SSD in the lower optical bay, plus numerous spinners, running Sierra, with 2 x 23" ACDs. It’s the base model Mac Pro 5,1, but it is still going strong touch wood and performs well enough for my tasks.

That said… for some time I’ve been considering my options for what comes next. As I see it, I have two paths, and both involve keeping my 23" ACDs:

  1. 2020 M1 Mac Mini 16GB/ largest SSD possible, PLUS a 6 bay NAS (for current and future needs) – both to be purchased 2nd hand, plus adapter/s to hook up the 2 ACDs, at a cost of around $2k.


  1. a 12 Core Mac Pro 5,1 with more RAM, a high end native graphics card to run the latest OS possible, PCIe card for the SSD, better USB and Bluetooth cards (for Air Drop etc).

Last year, when pricing a 12-core machine, I was looking at around $2k. I’m wondering now if the transition to Apple’s M series chips is going to see a glut of 12 core Pro’s on the market. If I can pick one up cheap, then price wise, it’ll be better to go with the old… rather than the new.

I’ve flip flopped on the idea over the past year… but more and more am leaning toward the 5,1, especially given my reticent feelings toward supporting Apple’s non-upgradeable machines.

There’s a YouTuber who repairs Macs/iPhones etc - he has posted several videos of his 5,1 that he’s maxed out, and on paper it certainly competes with the much more modern machines. I haven’t priced his particular setup, but - shows that it’s feasible in terms of achieving something comparable…

Are y’all embracing the M-line, or staying in obsolescence?

I only retired my 2008 Mac Pro (3,1) last year. I had upgraded it a lot and was quite fond of it, but I don’t think I’ll ever need a pro Mac again. I don’t miss the insane power consumption either. It used more power asleep (35W) than my Mac Mini when it’s hard at work.

I would think carefully about whether an M1 Mini is going to be able to drive your displays ok and what might happen when you have to replace them. I had to buy an eGPU when I upgraded my monitors to 27" 4K because the new Mini basically couldn’t run Lightroom anymore. You wouldn’t have that option with an M1 Mini because they don’t talk to eGPUs and you’re probably going to want hi res screens at some point.

I have no data to base this on, but my hunch is that the M1 Macs are going to get old really fast. A bit like the pre-SSD MacBook Airs. Groundbreaking and amazing at launch, but quickly overtaken by something much better.

If you’re not buying new and you like to hang onto your machines for a while, I think I’d probably look for a high spec Intel Mini, like the 3.2GHz 6 core i7 with a wicked fast SSD I’m writing this on.

Power consumption is certainly something I should be paying more attention to! I’d like to think I am environmentally aware, and sitting here in front of the Mac Pro, listening to its whirring fans… has probably become too ubiquitous…

To clarify re the Intel Mini Vs M1 Mini - can the Intel Minis better handle multiple high res displays than the M1?

I picked up my 2x 23" ACDs for about $80/ea… Looking now, I see the LED 27" models seem to have come down in price a bit - seems I could pick one up for around $200 - $250, which isn’t unreasonable… though if I’m getting 1, I’d get 2 and replace them both. That’s another $500 or so…

(Whilst my wife and I are on the best incomes of our lives, we’re saving to commit to a $650k+ homeloan, which is fucking scary! so being frugal is still very much the mindset…)

I’ve just purchased a 2012 i5 Mini to replace the MacBookPro5,5 we’ve been using in our bedroom as a Netflix/Plex box. So, am getting familiar with Intel Minis. It feels slow as hell compared to the MacPro and MacBookAir that I use daily - but as the MacRumors guys have pointed out - they are both using SSDs, but the Mini has a 5400 spinner… When I set up my dad’s new M1 iMac in a few weeks, I’m going to salvage the SSD out of his dying iMac, and am hoping it will fit in the Mini to speed it up.

Where was I? :slight_smile:

Oh right - so… I hadn’t considered a high end pre M1 Mini as an option, as I was kind of looking at it as - “Modern” vs “Old”. Checking eBay - a 2018 i7 Mini still sells for well over $1000… more than the M1… Again I guess is the question - is the i5 or i7 Intel Mini that much better than the M1?

Happy to consider it as an option instead of upgrading the Mac Pro… would still need to find a NAS…

So, rather hilariously, I’m back on a Mac Pro 5,1 as my primary workstation these days. Until recently, I was running a 2018 Mac mini with an eGPU attached as I needed to drive 3 displays. Before that (start of this year) I had an M1 mini before that which I ended up selling here because it could only drive 2 displays and had no eGPU support.

This little project, the OpenCore Legacy Patcher - has been a revelation.

I now have a boot screen for OS selection (Mac or Windows) plus I can run Big Sur with FileVault (the main reason I left the Mac Pro after High Sierra was that there was no official FileVault even with a GTX680 that had boot screen support).

My 5,1 was built up over many years, and is the Dual CPU tray model, with upgraded CPUs (X5677 which are each quad core @ 3.47GHz), an RX580 GPU, 64GB of RAM and a 2TB NVMe boot SSD in a PCIe slot.

Not sure I’d recommend anyone non-techy do the same. This is a great machine, but the future isn’t guaranteed. Monterey should work, from what I’m hearing, but it could break at some point. I’m happy to run this machine on Big Sur until there’s either a) a new Mac Pro desktop or I can pickup a 2019 Mac Pro second hand for a reasonable price ($10k+ is crazy!).

The biggest thing I love about being back is that my desk is now clear, and under my desk all the tech lives in one box. I previously had a Mac mini, an eGPU, a 4bay thunderbolt SATA enclosure, USB drives, dongles, the works. Now everything is in one sleek tower. The way it should be. :slight_smile:

That’s not helping, @jaysee :wink:

If I do stay with the 5,1… I’m not going to be flashing any graphics cards. I’d just get the best native option. The guy on YouTube in the above vid said he sourced a card from a modern iMac, thus it “just worked”. Not sure which OS he installed, but gathered it was very recent - the video was made late 2020.

If I go Mini… I’ve got 2 main data drives, and 2 back ups, as well as needing a scratch disk (and backup). Have always understood you don’t use your system disk for a scratch, so - would need a fast external as scratch…


A 12-Core just sold in eBay for about $800. It had enough RAM, but only the stock graphics card, no SSD. So - it was still probably $500 off being the perfect system for me.

I’m not running a flashed GPU. I’m running a standard PC RX580. OpenCore boots off a USB stick then displays the bootloader. :slight_smile:

Are you sure you need a Dual CPU board? You could get a single 6-core Xeon and 32GB pretty easily for your current machine for ~$300. Add an RX580 for $500 and you’re done.

BTW, don’t get me wrong, the M1 Macs are faster. But they don’t feel faster to me with what I do (especially thanks to the RX580), and the extra RAM / fast cheap SSD is more useful for me.

P.P.S. Only the M1 Max chips have a GPU faster than my RX580, which is a 4 year old graphics card. I think we’re going to have to wait for a new Apple Silicon Mac Pro before we see better performance than the current 2019 Mac Pro in GPU at least.

Thanks @jaysee :slight_smile:

Hugh Jeffreys on YouTube has put an AMD 5700XT in his 5,1. Looking on eBay - they’re around $1000. So - probably not going that route.

In all honesty, given I don’t see myself ever making money as a video editor, I probably don’t need the absolute best of the best 5,1 - but the thought was to have as good as I could get, so that it’s “less obsolete”…
