3 As of October 22, 2018. Radeon Instinct™ MI50 and MI60 “Vega 7nm” technology-based accelerators are PCIe Gen 4.0 capable providing up to 64 GB/s Peak bandwidth per GPU card with PCIe Gen 4.0 x16 certified servers. Peak theoretical transport rate performance guidelines are estimated only and may vary. Previous Gen Radeon Instinct compute GPU cards are based on PCIe Gen 3.0 providing up to 32 GB/s peak theoretical transport rate bandwidth performance.
Peak theoretical transport rate performance is calculated by Baud Rate * width in bytes * # directions = GB/s
PCIe Gen 3: 8 * 2 * 2 = 32 GB/s
PCIe Gen 4: 16 * 2 * 2 = 64 GB/s
Refer to server manufacture PCIe Gen 4.0 compatibility and performance guidelines for potential peak performance of the specified server models. Server manufacturers may vary configuration offerings yielding different results.

4 As of Oct 22, 2018. Radeon Instinct™ MI50 and MI60 “Vega 7nm” technology based accelerators are PCIe® Gen 4.0* capable providing up to 64 GB/s peak theoretical transport data bandwidth from CPU to GPU per card with PCIe Gen 4.0 x16 certified servers.
Previous Gen Radeon Instinct compute GPU cards are based on PCIe Gen 3.0 providing up to 32 GB/s peak theoretical transport rate bandwidth performance.
Peak theoretical transport rate performance is calculated by Baud Rate * width in bytes * # directions = GB/s per card
PCIe Gen3: 8 * 2 * 2 = 32 GB/s
PCIe Gen4: 16 * 2 * 2 = 64 GB/s
Vega20 to Vega20 xGMI = 25 * 2 * 2 = 100 GB/s * 2 links per GPU = 200 GB/s
xGMI (also known as Infinity Fabric Link) vs. PCIe Gen3: 200/32 = 6.25x
Radeon Instinct™ MI50 and MI60 “Vega 7nm” technology-based accelerators include dual Infinity Fabric™ Links providing up to 200 GB/s peak theoretical GPU to GPU or Peer-to-Peer (P2P) transport rate bandwidth performance per GPU card. Combined with PCIe Gen 4 compatibility providing an aggregate GPU card I/O peak bandwidth of up to 264 GB/s.
Performance guidelines are estimated only and may vary. Previous Gen Radeon Instinct compute GPU cards provide up to 32 GB/s peak PCIe Gen 3.0 bandwidth performance.
Infinity Fabric™ Link technology peak theoretical transport rate performance is calculated by Baud Rate * width in bytes * # directions * # links = GB/s per card
Infinity Fabric Link: 25 * 2 * 2 = 100 GB/s
MI50 |MI60 each have two links:
100 GB/s * 2 links per GPU = 200 GB/s
Refer to server manufacture PCIe Gen 4.0 compatibility and performance guidelines for potential peak performance of the specified server model numbers. Server manufacturers may vary configuration offerings yielding different results.

5 Calculated on Oct 22, 2018, the Radeon Instinct MI60 GPU resulted in 7.4 TFLOPS peak theoretical double precision floating-point (FP64) 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 1/2 FLOPS per clock for FP64. TFLOP calculations for MI60 can be found at https://www.amd.com/en/products/professional-graphics/instinct-mi60. External results on the NVidia Tesla V100 (16GB card) GPU accelerator resulted in 7 TFLOPS peak double precision (FP64) floating-point performance. Results found at: https://images.nvidia.com/content/technologies/volta/pdf/437317-Volta-V100-DS-NV-US-WEB.pdf. AMD has not independently tested or verified external/third party results/data and bears no responsibility for any errors or omissions therein.
6 ECC support on 2nd Gen Radeon Instinct™ GPU cards, based on the “Vega 7nm” technology has been extended to full-chip ECC including HBM2 memory and internal GPU structures.
7 Expanded RAS (Reliability, availability and serviceability) attributes have been added to AMD’s 2nd Gen Radeon Instinct™ Vega 7nm technology based GPU cards and their supporting ecosystem including software, firmware and system level features. AMD’s remote manageability capabilities using advanced out-of-band circuitry allow for easier GPU monitoring via I2C, regardless of the GPU state. For full system RAS capabilities, refer to the system manufacturer’s guidelines for specific system models.
