[4] Upgraded features from Nehalem include: All Sandy Bridge processors with one, two, or four cores report the same CPUID model 0206A7h[18] and are closely related.

[19] Ivy Bridge CPUs all have CPUID 0306A9h to date, and are built in four different configurations differing in the number of cores, L3 cache and GPU execution units: 1Processors featuring Intel's HD 3000 graphics are set in bold.

20× PCIe 2.0 [32] model Suffixes to denote: On 31 January 2011, Intel issued a recall on all 67-series motherboards due to a flaw in the Cougar Point Chipset.

Shipping of these new chipsets started on 14 February 2011 and Intel estimated full recovery volume in April 2011.

[42] After two weeks, Intel continued shipping some chipsets, but manufacturers had to agree to a set of terms that will prevent customers from encountering the bug.

[43] With Sandy Bridge, Intel has tied the speed of every bus (USB, SATA, PCI, PCIe, CPU cores, Uncore, memory etc.)

[44] With CPUs being multiplier locked, the only way to overclock is to increase the BClk, which can be raised by only 5–7% without other hardware components failing.

Sandy and Ivy Bridge processors with vPro capability have security features that can remotely disable a PC or erase information from hard drives.

[49][50] Sandy and Ivy Bridge processors contain a DRM technology that some video streaming web sites rely on to restrict use of their content.
