Memory support
Memory support	Four channels of DDR3-1066/1333/1600; up to 51.2 GB/s, without ECC. Intel's later comparison chart incorrectly lists two channels; the original brief and current specification page both establish four.	Up to 128 GB on the current Intel specification page; two channels; DDR4-2666; 41.6 GB/s; ECC not supported.
PCIe
PCIe	40 PCIe 2.0 lanes according to Intel's specification page.	PCIe 3.0; 16 CPU lanes: 1 × 16, 2 × 8 or 1 × 8 + 2 × 4. This excludes chipset lanes.
Chipsets
Chipsets	–	Intel 300-series motherboards; Z370 at launch. Older 100- and 200-series boards are incompatible despite sharing the LGA1151 socket (TechPowerUp and PC Gamer).
Process
Process	32 nm; Sandy Bridge-E. Package measures 52.5 × 45.0 mm; Intel states a 66.8°C maximum case temperature, not a junction-temperature rating.	14 nm; 37.5 × 37.5 mm package; 100°C maximum junction temperature.
Cooler
Cooler	Intel explicitly says the boxed processor has no fan or heatsink. Requires an LGA2011-compatible cooler and motherboard; Intel's product brief names the X79 platform.	No fan or heatsink included with the boxed processor (Intel specifications).
