Sandy Bridge

What is Sandy Bridge?

Sandy Bridge refers to the codename for the Intel processors typically belonging to the 2nd generation Core i3, Core i5 and Core i7 processors.

Technically, these CPUs are typically built on 32 nm node technology and use an LGA 1155 type socket. They usually come with two, four, and six cores.

Understanding Sandy Bridge

What is Sandy Bridge

Sandy Bridge of Intel is a microarchitecture of the processors of 2nd generation and is a successor to Nehalem microarchitecture and released in early 2011.

It has a relatively larger die size of 32 nm and is built on ‘tock’ technology, but offers reasonably high performance.

These processors belong to different processor families of Intel having different cores and designed to serve specific purposes such as:

The Sandy Bridge processors are codenamed differently depending on their design and features such as:

These CPUs are compatible with different operating systems of Windows apart from Linux such as:

The Sandy Bridge also supports different arch-specific and arch-favorable compilers such as:


There are lots of useful features and technologies included in the Sandy Bridge chip design that are upgrades from the previous chip designs.

Some of the notable features of Sandy Bridge CPUs are:


As for the architecture of the Sandy Bridge processors, it is completely redesigned as compared with its predecessors and comes with a brand new core design. Some of the notable architectural changes are:

Memory Subsystem:

The memory subsystem of the Sandy Bridge processors is also reworked to offer a faster performance as follows:

Translation Lookaside Buffer:

The Translation Lookaside Buffer of the Sandy Bridge processors is dedicated and comprises a dedicated instruction L1 TLB or ITLB, a data cache TLB or DTLB, and a unified L2 TLB or STLB, and is designed to perform as follows:

Questions & Answers:

Which Generation Does Sandy Bridge Belong to?

Typically, the Sandy Bridge processors belong to the 2nd generation of the Intel Core i3, Core i5, and Core i7 family.

Are Sandy Bridge Processors Still Good?

Yes, they are. Despite the fact that they belong to the 2nd generation of the Intel Core family, the Sandy Bridge Core processors can offer an admirable performance even when used for some demanding older games, as found in a few gaming benchmarks.

It is also quite good to perform normal and above-the-normal computing tasks. So, there is no doubt that Sandy Bridge CPUs are a popular choice among the users.

Does Sandy Bridge Support UEFI?

Yes, it does. In fact, several manufacturers of motherboards have moved on to UEFI or Unified Extensible Firmware Interface from the conventional 32-bit Basic Input Output System (BIOS).

When combined with a GPT partition, these specific types of processors do not have any problem booting to and accessing drives that may be as big as 2 TB or more.


As is common with Intel, they always come up with better processor architectures and designs.

And Sandy Bridge is another turning point with improved features, a better design and functionalities.

As a result, its growing popularity is no coincidence, and people are happy using the Sandy Bridge processors even today.
