As Mark already mentioned – PCIe speed has no impact on compile times. It’s only used for communication between CPU and {GPU, NVMe, Chipset}, or between GPU and RAM. > I want to buy from a physical store, not delivered by an on-line order, > in case there's a defect, so that I can easily take it back to the store.

That’s the way with AM3-socket APUs. It won’t be with AM4, but those are probably still a year away (at least half a year). Also, the new AM4 CPUs all have a basic iGPU inside, much like most Intels have had until now. They won’t be much to write home about, but will be sufficient for office and desktop. > I might be willing to get an Intel CPU, > but in their specifications there's no mention of PCIe (3 or 4) : > is this an accident or are PCIe's confined to AMD ? When I need such information, I like to go to Wikipedia. It has everything under one roof, often in very similar formats for both vendors. Here’s a description of Intel’s recent generation: https://en.wikipedia.org/wiki/Alder_Lake And as you can see, those have 16×PCIe 5 for the graphics slot and another 4×4.0, probably for NVMe. The chipset is connected via Intel’s proprietary DMI and connects to more mass storage, USB etc. > Does anyone have any useful advice or suggestions ? Well, we suggested stuff and advised on things. Please elaborate what hasn’t worked out for you and why. -- Grüße | Greetings | Salut | Qapla’ Please do not share anything from, with or about me on any social network.
