1 As of Oct 22, 2018. The results calculated for Radeon Instinct MI60 designed with Vega 7nm FinFET process technology resulted in 29.5 TFLOPS half precision (FP16), 14.8 TFLOPS single precision (FP32) and 7.4 TFLOPS double precision (FP64) peak theoretical floating-point performance. This performance increase is achieved with an improved transistor count of 13.2 billion on a smaller die size of 331.46mm2 than previous Gen MI25 GPU products with the same 300W power envelope.
The results calculated for Radeon Instinct MI50 designed with Vega 7nm FinFET process technology resulted in 26.8 TFLOPS peak half precision (FP16), 13.4 TFLOPS peak single precision (FP32) and 6.7 TFLOPS peak double precision (FP64) floating-point performance. This performance increase is achieved with an improved transistor count of 13.2 billion on a smaller die size of 331.46mm2 than previous Gen MI25 GPU products with the same 300W power envelope.
The results calculated for Radeon Instinct MI25 GPU based on the “Vega10” architecture resulted in 24.6 TFLOPS peak half precision (FP16), 12.3 TFLOPS peak single precision (FP32) and 768 GFLOPS peak double precision (FP64) floating-point performance. This performance is achieved with a transistor count of 12.5 billion on a die size of 494.8mm2 with 300W power envelope.
AMD TFLOPS calculations conducted with the following equation for Radeon Instinct MI25, MI50, and MI60 GPUs: 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 and 4 FLOPS per clock for FP16. To calculate FP64 TFLOPS rate for Vega 7nm products MI50 and MI60 a 1/2 rate is used and for “Vega10” architecture based MI25 a 1/16th rate is used.
TFLOP calculations for MI50 and MI60 GPUs can be found at https://www.amd.com/en/products/professional-graphics/instinct-mi50 and https://www.amd.com/en/products/professional-graphics/instinct-mi60

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.
