Power Efficiency

Unrivaled System-level Power Reduction

Overview

Through careful selection of silicon process and power-conscious architecture design, AMD devices deliver power efficiency across all product portfolios, including adaptive SoC platform devices, Spartan™ 6 FPGAs, 7 series FPGAs, UltraScale™ FPGAs, UltraScale+™ FPGAs, and adaptive SoCs. With each generation, AMD broadens its power-reduction capabilities, ranging from process enhancements, architectural innovations, aggressive voltage scaling, and advanced software optimization strategies. More details on portfolio-specific capabilities, silicon process advantages, and benchmark comparisons are shown below. Power estimation, thermal models, full software support, and demonstration boards are publicly available for all families. Designing power for AMD devices is easier than ever before with comprehensive documentation, built and tested power reference designs, and powerful tools to unlock the potential of your next design to get the most out of your adaptive SoC, SoC, or FPGA.

Versal Adaptive SoC

The Versal™ adaptive SoC is the next-generation, heterogeneous compute device built on TSMC’s 7nm HK-MG FinFET process, taking the next leap in low-power and high-performance technology through architectural innovation and power-optimized blocks. The Versal AI Engine architecture delivers up to 40% power savings for compute-intensive 

  • Hardened block RAM, UltraRAM, and DSP blocks improve device efficiency
  • More efficient DSP blocks for enhanced complex and floating-point math operations
  • Unused block RAMs support power gating to avoid power leakage
  • UltraRAM initialization and width configurability reduce the need for external RAM/ROM

The combination of Versal adaptive SoC hardened and programmable blocks allows designers to maximize performance per watt by including previous generation power-saving techniques, as well as improved power management, new voltage and frequency scaling, and integrated system monitoring for board-level, intelligent power management.

UltraScale+ FPGAs

Built on TSMC’s 16nm FinFET+ high-performance, low-power semiconductor process, the UltraScale+ device families deliver up to 60% overall device-level power savings over 7 series FPGAs and SoCs. Architectural enhancements include:

  • Hardware-based clock gating
  • Hardened block RAM cascading
  • DSP block efficiencies
  • Power-optimized transceivers

Through architectural innovation and dual-voltage operation of the primary core fabric, UltraScale+ families more than double the performance per watt capabilities of 7 series families by realizing power reductions while improving overall performance.

Thermal Design:

Understating the thermal design limits of an application varies greatly between application types and end markets, a lower power design at a high ambient can experience the same thermal challenges as a high power design at a much lower ambient and so understanding what the limits of a system are is critical for both a successful product and a cost effective product, as overdesign a thermal solution incurs extra cost and complexity to a design.

To this end AMD provides DELPHI thermal models for all of current devices, these support both Siemens Flotherm and Ansys IcePak.

Thermal simulation is a critical step in board design and as indicated in the board methodology process chart, the results of the initial estimation should be used for the thermal solution validation.

Thermal Design Partners

Not all customers have access to either the thermal simulation tools or the resources to run a thermal simulation, through the AMD Alliance program you can access partners that have Thermal design capability.

Package selection

An important part of device selection is selecting the right package for a successful thermal design. AMD devices are available in many package types to cater for different customers requirements, however from a thermal standpoint the Lidless packaging offers the best thermal performance, AMD devices are offered in the following packages:


Bare Die – Package Designator (SB/VB)

  • "B" indicates Bare Die, S for 0.8mm & V for 0.92mm package pitch

Lidded -  (SF/VF)

  • "F" For Forged Lid, S for 0.8mm & V for 0.92mm package pitch

Lidless Package (VS/LS)

  • "S" indicated the Stiffener Ring, V for 0.92mm & L for 1mm pitch
  • Provides optimal Thermal Performance


Lidless Overhang Package (VI)

  • "I" indicates a stiffener ring with package overhead (package substrate larger than the BGA footprint)
  • "V" indicates 0.92mm package pitch
  • Provides optimal Thermal Performance
