As the title suggests can anyone explain why the CPU lanes are so less these days? Most CPUs come with only 20 pcie lanes. Out of them 16x goes to GPU and 4x goes to NVME drives.
Now if i add another NVME drive, then i guess the GPU goes into 8x mode and 4x are sort of wasted (the two NVME taking 4x each).
So why don't manufacturers increase the lanes. Also i find that many times it mentions that certain SATA port / PCIe will be disabled if NVME is used. Why is INTEL / AMD stingy with PCIe lanes? If i remember correctly earlier high end CPU used to come with upto 40 lanes (back in the days)
