Intel Sandy Bridge vs Ivy Bridge
From Free Knowledge Base- The DUCK Project: information for everyone
The terms Sandy Bridge and Ivy Bridge refer to lines of Intel Processors. These lines of computer processors are also termed as architectures.
Sandy Bridge
Intel introduced Sandy Bridge at the start of 2011. Sandy Bridge replaces the Nehalem architecture.
- 32 nanometer manufacturing process
- planar double-gate transistors
Ivy Bridge
Intel introduced Ivy Bridge in 2012 to replace the Sandy Bridge architecture. Ivy Bridge processors are backwards compatible with the Sandy Bridge platform, but such systems might require a firmware update.
- 22 nanometer manufacturing process
- FinFET ("3D") tri-gate transistors
The Ivy Bridge CPU microarchitecture is a shrink from Sandy Bridge and remains largely unchanged. The new tri-gate transistors reduce power consumption by half while offering the same performance level as 2-D planar transistors.
