Excavator Processor

What is Excavator Processor?

AMD Excavator processors belong to the Family 15h desktop CPU line, and according to a statement from AMD, it also signifies the code name of the 4th generation cores designed on the Bulldozer microarchitecture, named Carrizo, Bristol Ridge, and Stoney Ridge.

These CPUs are built using the 28 nm manufacturing process and different sockets such as FM2+, AM4, and FP3 for different chips.

Designed and developed by AMD, technically, the processors come with high density or thin libraries that increase energy efficiency and instructions per clock cycle.

Understanding Excavator Processor

Excavator Processor

The Excavator processors are developed by AMD and are the successors to the Steamroller Family 15h processors and the predecessors of the x86-64 Zen architecture.

Built on an improved Bulldozer microarchitecture, these chips are designed to be used as normal CPUs and also as Accelerated Processing Unit (APU) processors.

First released on October 12, 2011, these processors are deemed by AMD to be the 4th generation Family 15h desktop processors derived from Bulldozer cores.

Talking about cores, there are different core names for these processors such as:

Different models of the Excavator processors come with different socket types based on the cores such as:

Other models use the FP3 (µBGA) type of socket.

The foundational Bulldozer microarchitecture of the Excavator processors is much improved to offer higher performance and energy efficiency with the following:

In fact, the improved microarchitecture of the Excavator chips has everything in between to make it more powerful and efficient.

The improved architecture of the Excavator processors also included additional hardware support for new sets of instructions as follows:

In fact, the better design of the Excavator CPUs increases energy efficiency by 30% and gives it the power to process more Instructions per Cycle (IPC) by up to 15% with respect to the previous CPU from AMD, the Steamroller.

AMD also released the APUs based on the Excavator in 2015, called the Carrizo. These were meant to be used for mainstream applications.

These APUs are designed to be Heterogeneous System Architecture or HSA 1.0 compliant.

Later on, AMD went on to produce and release other variants of CPUs and APUs based on Excavator, called Toronto, targeting the enterprise and server markets.

However, typically, the Excavator family of processors is considered to be the ultimate revision of the Bulldozer.

The Excavator was succeeded about a year later, in early 2017, by two new microarchitectures.

General Specifications and Information

Here are some other important aspects of the Excavator CPUs, summarized for you:

Ideally, the AMD Excavator processor, based on the evolved microarchitecture of Bulldozer, is cheap and efficient and perhaps one of the best entry-level solutions that can compete against the low-end CPUs from Intel, including the Atom-class CPUs.

Conclusion

The Excavator processors, as you can see, are designed by AMD to offer the users significant performance benefits with improved energy efficiency and higher throughput.

The architecture of these processors is considered to be the height of the Bulldozer microarchitecture, which is the basis of their build and cores.
