The Next Era of Compute and Machine Intelligence

THE WORLD’S FASTEST TRAINING ACCELERATOR
FOR MACHINE INTELLIGENCE AND DEEP LEARNING1
The Radeon Instinct™ MI25 accelerator, designed with the most
advanced Next-Gen “Vega” GPU architecture, is the ultimate
training accelerator for large scale machine intelligence and
deep learning, along with being an optimized open compute
workhorse for single-precision HPC-class system workloads.
The MI25 delivers leadership in FP16 and FP32 performance in
a passively-cooled single GPU server card with 24.6 TFLOPS of
FP16 and 12.3 TFLOPS of FP32 peak performance through its 64
compute units with 4,096 stream processors.1
The Radeon Instinct MI25’s powerful compute engine and
advanced memory architecture, combined with AMD’s ROCm
open software platform and ecosystem, provides a powerful,
flexible heterogeneous compute solution that allows datacenter
designers to meet the challenges of a new era of compute and
Machine Intelligence.

AMD’s Radeon Instinct™ MI25, combined with
the ROCm open software platform and MIOpen
libraries, delivers superior performance per
watt for deep learning training deployments in
the datacenter.2

FOOTNOTES
1. Measurements conducted by AMD Performance Labs as of June 2, 2017 on the Radeon Instinct™ MI25 “Vega” architecture based accelerator.
Results are estimates only and may vary. Performance may vary based on use of latest drivers. PC/system manufacturers may vary configurations
yielding different results. The results calculated for Radeon Instinct MI25 resulted in 24.6 TFLOPS peak half precision (FP16) and 12.3 TFLOPS peak
single precision (FP32) floating-point performance.
AMD TFLOPS calculations conducted with the following equation: FLOPS calculations are performed by taking the engine clock from the highest
DPM state and multiplying it by xx CUs per GPU. Then, multiplying that number by xx stream processors, which exist in each CU. Then, that number
is multiplied by 2 FLOPS per clock for FP32. To calculate TFLOPS for FP16, 4 FLOPS per clock were used. The FP64 TFLOPS rate is calculated using
1/16th rate.
External results on the NVidia Tesla P100-16 (16GB card) GPU Accelerator resulted in 18.7 TFLOPS peak half precision (FP16) and 9.3 TFLOPS peak
single precision (FP32) floating-point performance.
Results found at: https://images.nvidia.com/content/tesla/pdf/nvidia-tesla-p100-PCIe-datasheet.pdf.
External results on the NVidia Tesla P100-SXM2 GPU Accelerator resulted in 21.2 TFLOPS peak half precision (FP16) and 10.6 TFLOPS peak single
precision (FP32) floating-point performance.

2. Measurements conducted by AMD Performance Labs as of June 2, 2017 on the Radeon Instinct™ MI25 “Vega” architecture based accelerator.
Results are estimates only and may vary. Performance may vary based on use of latest drivers. PC/system manufacturers may vary configurations
yielding different results.
The results calculated for Radeon Instinct MI25 resulted in 82 GFLOPS/watt peak half precision (FP16) or 41 GFLOPS/watt peak single precision
(FP32) floating-point performance.
AMD GFLOPS per watt calculations conducted with the following equation: FLOPS calculations are performed by taking the engine clock from
the highest DPM state and multiplying it by xx CUs per GPU. Then, multiplying that number by xx stream processors, which exist in each CU. Then,
that number is multiplied by 2 FLOPS per clock for FP32. To calculate TFLOPS for FP16, 4 FLOPS per clock were used. The FP64 TFLOPS rate
is calculated using 1/16th rate. Once the TFLOPs are calculated, the number is divided by the xxx watts TDP power and multiplied by 1,000 to
determine the GFLOPS per watt.
Calculations conducted by AMD Performance Labs as of June 2, 2017 on the NVidia Tesla P100-16 (16GB card) GPU Accelerator to determine
GFLOPS/watt by dividing TFLOPS results by 250 watts TDP resulted in 75 GFLOPS per watt peak half precision (FP16) and 37 GFLOPS per watt peak
single precision (FP32) floating-point performance.

Calculations conducted by AMD Performance Labs as of June 2, 2017 on the NVidia Tesla P100-SXM2 GPU Accelerator to determine GFLOPS/
watt by dividing TFLOPS results by 300 watts TDP resulted in 71 GFLOPS per watt peak half precision (FP16) and 35 GFLOPS per watt peak single
precision (FP32) floating-point performance.

3. ECC support is limited to the HBM2 memory and ECC protection is not provided for internal GPU structures.
4. The Radeon Instinct GPU accelerator products come with a three year limited warranty. Please visit www.AMD.com/warranty for details on the 		
specific graphics products purchased. Toll-free phone service available in the U.S. and Canada only, email access is global.
5. Support for Python is planned, but still under development.
6. Data based on AMD Engineering design of Vega. Radeon R9 Fury X has 4 geometry engines and a peak of 4 polygons per clock.
Vega is designed to handle up to 11 polygons per clock with 4 geometry engines. This represents an increase of 2.6x. VG-3
