AMD Zen is the company's new high-performance CPU microarchitecture and with which it hopes to become competitive again in the high-end processor market. This new architecture will debut with Summit Ridge processors with configurations of up to 8 cores and 16 threads.
AMD Zen: everything you need to know about AMD's new CPU microarchitecture
Development of AMD Zen began four years ago following the need for a major change given the poor success of Bulldozer-based FX processors and their successive revisions. Zen is a completely new microarchitecture that has been designed from scratch and invested millions of working hours
Four years ago, AMD embarked on a journey that doesn't usually happen in the semiconductor industry, when we took a zero-point approach to developing a design for our next high-performance CPU engine to build an up- to-date x86 computing core. of the demands of the current market. AMD Zen is highly scalable so it will be present in all kinds of products from super efficient laptops to high performance servers.
The fundamental pillars of Zen
AMD Zen's innovation focuses on three fundamental areas:
- Performance of the engine itself with completely new jump prediction, the introduction of a micro-op cache and a much wider instruction window than what was present in its predecessors.
- Performance: prefetch and a new cache hierarchy with 8MB of L3 cache data and instructions to maintain high engine performance.
- Efficiency: AMD Zen is developed with advanced 14nm FinFET technology and a host of architecture-saving power design techniques that enable it to deliver much higher performance per watt consumed than previous generations.
A design focused on maximum performance
The new AMD Zen core design abandons the modular design introduced with the Bulldozer and which has not yielded the expected results. This means that each of the cores has all the necessary elements, thus avoiding the bottlenecks that occur when sharing elements between the different cores. This new approach greatly enhances Zen's performance per clock cycle (IPC) to the point of exceeding by 40% that offered by Excavator, the latest evolution of the original Bulldozer.
The Zen core has twice as many integer units (ALUs), decoders, and floating point units compared to Excavator. In a simple way, it could be said that each Zen core is equivalent in “muscle” to two Excavator cores, demonstrating the enormous progress that has been achieved in this regard. Each Zen core consists of 4 decoders, 4 ALUs, and four 128-bit floating point units divided into two 256-bit FMACs. Along with this, the premiere of a SMT technology very similar to Intel's HyperThreading to be able to handle a large number of processing threads.
New AM4 socket updates AMD platform
In its effort to fight again with the best competitive processors AMD has created the new AM4 socket for Zen and a new platform with native support for the most modern technologies, among which we highlight the new DDR4 RAM, the interface for graphics cards PCI Express 3.0, USB 3.1, NVM Express and SATA Express. With this, a new ecosystem is created so that users can enjoy the best of new information technologies.
