Find and price out an “equivalent” PC to the new MacPro. Make sure it truly IS an equivalent professional grade workstation. You may find it very difficult to do.

Here's a PC equivalent of the low end Mac Pro 8 core:

And here is a 28 core:

You are correct, sir. And then also consider if the thermal solution is not right, your chip “rated” for speed will perform terribly. You cannot put a crappy cheap MB and case and get good thermal performance - the chip will throttle down to say cool.

Saw a price tag on one but not the 28 core....

Nice try. . . But that’s PC has a six core Intel 2133 Xeon W, I.e. it’s using an inexpensive Xeon with only a 8.25 MB cache, a $617 processor introduced in the 3rd quarter of 2017.

Apple’s MacPro uses an eight core Intel 3225 Xeon W in its lowest model with a total of 24.5 MB cache, introduced in June 2019. That’s an $1149 processor. Big difference. Customization doesn’t allow the choice to upgrade to this year’s Xeon. Oops! Add a 10 core Intel Xeon W to get close, $1005

Secondly, the PC is configured with only 16GB of ECC 2666GHz RAM and a slow 256GB SSD. The MacPro comes standard with 32GB of ECC 2666 GHz RAM and a very high speed 256GB SSD. $20.

The PC’s mother board’s system bus is only 24 lanes wide even though the Xeon processor is capable of 48. The Apple custom designed by Apple logic board bus is a full 48 lanes wide allowing direct access to RAM and graphics processors for all cores. Not a fixable failure of this workstation. Unknown.

The PC’s default power supply is only 850 watts. The Apple MacPro comes with a 1450 watt p/s. Upgrading the PC to a 1600 watt p/s adds — $355.

Video on the PC is using on-motherboard intel graphics (ROTFLMAO!) while the basic Apple MacPro has an AMD Radeon Pro 580X with 36 compute units, 2304 stream processors, 8GB of GDDR5 memory producing up to 5.6 teraflops at single precision math. It has two HDMI 2.0 ports on card four DisplayPort connections routed to system to support and two internal Thunderbolt 3 ports which has support for up to six 4K displays, two 5K displays, or two 32” 6K Pro Display XDRs. Upgrading the PC with a somewhat equivalent graphics from their available choices adds $920.

The PC has no WIFI OR Bluetooth, the MacPro comes standard with both. Add $50.

The PC has no hot swapping drive trays, the MacPro has four. Add four to the PC: $65.

The PC has only three PCIe 16/8 combination slots, while the MacPro has eight and two dedicated half length 8 slots. No cure for this deficiency internally, you’d have to buy an external card cage.

The PC doesn’t come with a keyboard or mouse. The MacPro comes with a wireless keyboard and wireless mouse. The suggested Logitech keyboard & mouse add only $30.

Total price resulting from the close build is $ 5,150.00 . . . and you still haven’t matched MacPro in features or software included.

Well, your 28 core was closer to the mark. Their base unit used a Xeon from 2018, but they allow you to upgrade it to the Xeon W 3275 released in the 1st Quarter 2019 Apple is using for a mere $1995. Upgrades to ECC 2933GHz RAM from 2666, are necessary. . . and again from a slow to a fast SSD. Also they don’t include keyboard and mouse. The video card had to be upgraded from their bare minimum 2GB to something close to the minimum you can get with the Apple MacPro, but that still added $1435. There wasn’t much more you could add. Price comes up to around $14,894.
