PCIe 4.0 or Gome Home

Go Home Intel - you are 14 nm and PCIe 3.0

AMD is 7 nm and PCIe 4.0

Arm is 7nm and PCIe 4.0/5.0 + CCIX, CXL, Gen-Z

IBM is 7 nm and PCIe 4.0/5.0, CCIX, CXL, Gen-Z + OpenCAPI


Intel is looking at 11nm and 9nm

AMD is looking at 5nm

Arm is looking at 3nm

IBM is looking at 3nm

IBM is in the lead; Arm is a stable second, AMD is a distant third and Intel is barely visible - the nature of those stuck with cash-cow-syndrome like Cisco
