Can't remember building a Desktop-PC from scratch before, but have experience working with hardware.
Use-cases for “Das Quad-Boot”:
- Natively boot macOS (Hackintosh), FreeBSD, Linux, Proxmox/ESXi, Win 10
- IDEs, shell/admin
- common office work
- Light gaming (>5y old titles)
There's reasoning on my parts choice in the bottom comment.
Did I overlook an ncompatibility?
Your feedback is much appreciated!
If you want or need ECC memory you can get the same processor like an i7-10700, which is called the Xeon® W-1270, which is identical with the only difference being the “you paid ransom to use ECC memory” flag set. Of course you need an even more expensive W480 chipset for that. It's identical to a Z490, but has the same ECC flag activated. That difference alone will set you back > 200€.
And no, you do not get other improvements for that price difference.
It's a basically a scam…
To put that into perspective. intels Consumer core-i and HEDT (“High end” Desktop) Core X/XE CPUs as well as Xeon®-W processors allow you to use 16 PCIe lanes. You need those 16 to fully utilise a dedicated GPU.
Where does everything else connect? To the chipset which is connected via DCI to the CPU. Basically 4 extra PCIe lanes.
M.2 NVMe PCIe 3.0/4x slots? A *single* SSD maxes out that connection. Got two of those? They share the bandwidth… with Gbit/s ethernet, or 2.5Gbit/s, ALL USB ports…
and they claim USB 3.2 Gen 2 can do 10Gbit/s transfer speeds. Unless you use your SSD or ethernet, or WiFi, or Bluetooth, or USB or Audio or SATA ports at the same time.
The other “4x” or “1x” PCIe slots on your motherboard… they share those 4 PCIe lanes with everything else as well.
That means it's technically impossible to actually use all of those peripherals to their full performance.
Why is intel still getting away with that? They're a de-facto monopoly… intel needs more competition!
@MacLemon how's AMD looking in comparison?
@morre Ryzen CPUs sport more than 16 PCIe lanes. (On intel you can only get more than 16 with Xeon® E- processors)
The whole Ryzen lineup supports ECC memory as well as overclocking and Quad-Channel Memory access if I'm not mistaken.
Haven't dug deep enough into Ryzen and its Chipsets yet, to make a qualified statement.
Also AMD is releasing the Zen 3 architecture with their (supposedly called) Ryzen 5000 series today (2020-10-08), so that may change things in AMDs favour even more.
@morre AMD Zen2 Ryzen CPUs in AM4 socket also only support Dual-Channel DDR4 RAM. Though at 3200MHz out of the box (opposed to 2666MHz for i3/5/7 and 2933MHZ for the i9 series. If you want faster RAM with intel CPUs you must cough up for their more expensive K-SKUs and overclock. You can further overclock all AMD Ryzen CPUs and RAM access speeds.)
If you want Quad-Channel Memory you must go Threadripper, but I wouldn't deem those “Consumer” Desktop CPUs anymore.
@MacLemon AMD, too has only 16 PCI-E lanes for his consumer products.
Maybe there is no demand, to provide more lanes for IO at the consumer market
@MacLemon yeah it's really bad with what Intel charges you. Iirc for a server board with ecc you could also use a c481 or so chipset? Funny enough with that you can use ecc but when you don't use a Xeon you can only use it with like pentiums and stuff. So no mid range regarding performance just very low or "normal" but extremely expensive. I know why I liked AMD always more.
@MacLemon thanks for this analysis, I think it explains a mystery that I hated at work!
