AMD EPYC™

The New x86 Option

AMD's return to the CPU segment delivers a whole new value proposition to the x86 world. Built on GIGABYTE's extensive design expertise across a range of chipset platforms, this AMD EPYC™ platform is already receiving acclaim for its high specification:

  • Memory
  • I/O
  • Network connectivity

This platform is intended as an alternative for builders in the x86 space and packs a real punch in flexibility and expansion options.

Memory Optimization
  • Memory speed of up to 2666MHz (at 1DPC) Total memory capacity of 4TB supported
PCIe Lanes
  • Up to 128 lanes in both 1P and 2P offerings providing the highest expandability options of any x86 platform
Cores / Power
  • CPU power is managed at the core level, meaning that power is allocated only for specific workload needs
Security
  • Proprietary AMD security on chip

Comprehensive I/O

Both single- and dual-socket CPUs come equipped with 128x PCIe lanes, providing extensive I/O options. This is a huge improvement in I/O vs. incumbent x86 offerings.
Increased I/O allows for flexibility in extending your storage, networking or compute to a level previously unattainable with standard server motherboards.
In addition, the integrated nature of the processor - designed as a system-on-chip (SoC) - means that there is no need for a separate PCH and less additional switches needed for expansion lanes.

Dense, High Speed Storage Support

Onboard U.2 + M.2

GIGABYTE AMD EPYC™ platforms are designed to support U.2 and M.2 storage devices. Both use the NVMe protocol, taking advantage of the fast bandwidth of PCIe Gen3 x 4 lanes to deliver up to 32 Gb/s data transfer speeds, over 4 times the performance of SATA 3, giving you more flexibility to integrate some of the most dense and fastest storage devices on the market into your system.

Data Security

TPM 2.0 Module

GIGABYTE's EPYC™ platform is designed to support Trusted Platform Modules (TPM - discrete cryptographic on-board processors).

Carefully Selected Components

GIGABYTE's passive components are meticulously selected to guarantee a super stable operating environment and allow the processors and the memory to deliver their maximum performance. GIGABYTE's server motherboards are built with ultra long lasting components for the highest reliability attainable which allows us to offer some of the most durable servers in the industry.

Ease of Deployment and Management

GIGABYTE is always responsive to market needs and user-friendly solutions, including:

  • Tool-less rail kit included as a default across all new server models
  • In-house designed proprietary tool-less sleds for 3.5" HDDs to allow for easy swapping
  • Supplying multiple connector options and tools where appropriate

Efficient, Reliable Power Supply

All of GIGABYTE's new generation servers are guaranteed to offer a conversion efficiency of >90% regardless of load. This, combined with GIGABYTE's precision design, translates to super efficient power usage which maximizes the system's power:performance ratio and cuts OPEX for the end user.
