Hey guys and gals,
I plan on updating my computer from a 2014 build, and the number PCIe lanes I had available was never really looked into all that much. But now I guess I'm paying attention a bit more and I want to run my thoughts on this for the community to see if I’m thinking correctly. I plan on building a smaller computer, making use of a mini ITX board and installing that into a small case (for whatever reason, I just like the idea of having somewhat of a powerhouse in a tiny box). I’ll likely be getting a i5 8600 or i7 8700 (since the case will be quite small, I don't think I'm going to overclock--I've actually never needed to overclock because of gaming--I just did it for fun when I'd make my build just to see what happened).
From what I can tell, those CPUs afford 16 PCIe 3 express lanes. I plan on using an m2 NVMe SSD and one graphics card. If I understand things correctly, the NVMe can use up to 4 lanes and the graphics card can use up to 16 (making a total of 20), and the motherboard chipset can add additional lanes, but at a cost (i.e., those additional lanes aren’t quite as fast as the direct lanes found on the CPU). At this moment I find B360, H370, H310, and Z370 boards are my options, but the h310 is out because I’ll be using an NVMe drive.
Question: it looks like the h370 has 20 lanes available and the B360 has 12 max lanes. With the addition of the CPU, am I right in thinking that the B360 would have a total of 28 (16+12)? If I had one graphics card using 16 and one NVMe using 4, that is all I need, correct? If I’m using only one GPU (I’m assuming that would take up the 16 available lanes of the CPU), then I only need 4 additional lanes, right? Or is there more to the story? Thanks for your time.
