Atlas KREX-X Series

The KREX-X Series is a family of high-performance desktop and workstation processors developed by Atlas Dynamics. The processors are based on the fourth generation of the KREX microarchitecture and represent the flagship consumer computing platform produced by the company.

Introduced in 2030, the series emphasizes high clock frequencies, large shared cache capacity, and integrated artificial intelligence acceleration. The processors are manufactured using a 2 nm0.4 Luntocahr class fabrication process and utilize a chiplet-based design that separates compute, cache, and I/O functions across multiple dies connected through the Atlas HyperMesh interconnect.

The flagship model of the series is the KREX-X909 Titan Pro, which represents the highest-performance configuration available in the lineup.

Overview

The KREX-X Series was designed for enthusiast desktop systems, high-end workstations, and compute-heavy professional workloads. The processors prioritize high single-thread performance while maintaining strong multi-threaded throughput.

Processors in the lineup employ a hybrid core configuration consisting of Performance Cores and Throughput Cores. Performance Cores are designed for high clock speeds and wide execution pipelines, while Throughput Cores provide efficient scaling for heavily parallel workloads.

Each processor integrates Atlas Infinity Cache, a large shared cache system intended to reduce memory latency and improve performance in memory-sensitive workloads such as gaming, simulation, and content creation.

The processors also incorporate a dedicated neural processing unit designed for artificial intelligence inference workloads and local machine learning applications.

Architecture

KREX-X processors are based on the KREX v4 microarchitecture. The design includes an eight-wide instruction decode pipeline and a large micro-operation cache intended to maintain high instruction throughput at elevated clock frequencies.

The architecture supports the KREX-V512 vector instruction extensions and the third-generation KREX Tensor Array engine, which accelerates matrix operations commonly used in machine learning workloads.

The processors are built using a modular chiplet design consisting of a compute tile, cache tiles containing Atlas Infinity Cache, and a separate I/O tile responsible for memory controllers and platform connectivity.

These tiles communicate through Atlas HyperMesh, a high-bandwidth interconnect providing multi-terabyte per second internal data transfer rates.

The memory subsystem supports up to eight channels of DDR6 memory with error correction capabilities. Advanced prefetch and cache management systems are used to reduce memory latency during large data workloads.

Features

Major architectural and platform features of the KREX-X Series include hybrid Performance and Throughput cores, large shared Atlas Infinity Cache, and support for the KREX-V512 vector instruction set.

The processors support DDR6-9600 and LPDDR6X memory technologies and provide high bandwidth memory access through multi-channel controllers.

Hardware security features include encrypted register states, hardware shadow stacks, and memory tagging intended to mitigate certain classes of software exploitation.

Connectivity support includes PCI Express 6.0 expansion capability and modern high-speed storage interfaces through the platform controller.

Models

The KREX-X Series consists of several processor models positioned at different performance tiers within the high-end desktop segment.

The entry configuration of the series is the KREX-X901 Base, which provides sixteen cores and thirty-two threads. This processor is designed for high-performance consumer desktop systems while maintaining lower power consumption relative to higher models.

Above this model is the KREX-X903 Core, which increases total core count and clock frequencies to provide improved performance in workstation workloads and demanding applications.

The KREX-X905 Apex represents a higher performance tier within the lineup and includes increased cache capacity and higher boost frequencies.

The KREX-X907 Titan is positioned near the top of the product stack and offers additional cores, higher sustained clock speeds, and expanded cache resources.

At the top of the lineup is the KREX-X909 Titan Pro, the flagship processor of the KREX-X Series. This model provides the maximum core count, the highest clock frequencies, and the full configuration of the Atlas Infinity Cache system. The processor is targeted at enthusiast systems, advanced workstation platforms, and compute-intensive professional workloads.

Platform

KREX-X processors utilize the Atlas FCLGA-6120 socket and are designed for high-end desktop motherboards using the Atlas workstation chipset platform.

The platform supports large memory configurations using multi-channel DDR6 memory and provides extensive high-speed connectivity including PCI Express 6.0 expansion capability.

Integrated platform features include multiple NVMe storage interfaces, high-speed networking controllers, and support for modern display output standards through the integrated graphics subsystem.
