The new AMD Radeon Instinct™ MI60 and MI50 accelerators were designed to efficiently process workloads such as rapidly training complex neural networks, delivering higher levels of floating-point performance, greater efficiencies and new features for datacenter and departmental deployments1.
The AMD Radeon Instinct™ MI60 and MI50 accelerators provide ultra-fast floating-point performance and hyper-fast HBM2 (second-generation High-Bandwidth Memory) with up to 1 TB/s memory bandwidth speeds. They are also the first GPUs capable of supporting next-generation PCIe® 4.02 interconnect, which is up to 2X faster than other x86 CPU-to-GPU interconnect technologies3, and feature AMD Infinity Fabric™ Link GPU interconnect technology that enables GPU-to-GPU communications that are up to 6X faster than PCIe® Gen 3 interconnect speeds4.
Key features of the AMD Radeon Instinct™ MI60 and MI50 accelerators include:
Optimized Deep Learning Operations: Provides flexible mixed-precision FP16, FP32 and INT4/INT8 capabilities to meet growing demand for dynamic and ever-changing workloads, from training complex neural networks to running inference against those trained networks.
World’s Fastest Double Precision PCIe®2 Accelerator5: The AMD Radeon Instinct™ MI60 is the world’s fastest double precision PCIe 4.0 capable accelerator, delivering up to 7.4 TFLOPS peak FP64 performance5 allowing scientists and researchers to more efficiently process HPC applications across a range of industries including life sciences, energy, finance, automotive, aerospace, academics, government, defense and more. The AMD Radeon Instinct™ MI50 delivers up to 6.7 TFLOPS FP64 peak performance1, while providing an efficient, cost-effective solution for a variety of deep learning workloads, as well as enabling high reuse in Virtual Desktop Infrastructure (VDI), Desktop-as-a-Service (DaaS) and cloud environments.
Up to 6X Faster Data Transfer: Two Infinity Fabric™ Links per GPU deliver up to 200 GB/s of peer-to-peer bandwidth – up to 6X faster than PCIe 3.0 alone4 – and enable the connection of up to 4 GPUs in a hive ring configuration (2 hives in 8 GPU servers).
Ultra-Fast HBM2 Memory: The AMD Radeon Instinct™ MI60 provides 32GB of HBM2 Error-correcting code (ECC) memory6, and the Radeon Instinct™ MI50 provides 16GB of HBM2 ECC memory. Both GPUs provide full-chip ECC and Reliability, Accessibility and Serviceability (RAS)7 technologies, which are critical to deliver more accurate compute results for large-scale HPC deployments.
Secure Virtualized Workload Support: AMD MxGPU Technology, the industry’s only hardware-based GPU virtualization solution, which is based on the industry-standard SR-IOV (Single Root I/O Virtualization) technology, makes it difficult for hackers to attack at the hardware level, helping provide security for virtualized cloud deployments.

Re: AMD Vega - Info, spekulace
bohužel je to tak... alespoň těch 7nm to zachraňuje, ten samý čip na 14/12nm by byl enormě velký a díky FP64 by žral klidně dvojnásobek toho co Vega 20 na 7nm. Což jen dokazuje že s GCN GPU prostě na 7nm přejít museli a nic jiného jim de fakto nezbývalo....yuri.cs píše:Frekvence o 300MHz vyssi, TDP 300W... Klasicka Vega.
závěr: 7nm NAVI nezachrání

Na 300GB/s s NVLink 2.0 to sice nemá, ale furt lepší jak nicPrevious 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

Re: AMD Vega - Info, spekulace
Vega 20 je o 45% menší než Vega 10. Jádro o velikosti 332mm2 dosahuje cca 68% plochy Vegy 10 výraběné 14nm Fin Fet procesem-The total number of transistors of Vega 7 nm to be mounted is 13.2 billion and the die size is 332 mm 2 . As Vega 10 manufactured using the 14 nm process technology sequentially has 12.5 billion and 486 mm 2 , the number of transistors has increased by about 6%, while the die size is reduced to about 68%.
takty (max boost clock) jsou o 20% vyšší jak u Vegy 10.I was able to ask. Using this formula, back calculation from the theoretical performance value of 14.7 TFLOPS, the boost maximum clock of Vega 7 nm should be around 1794 MHz. I think that about 16% higher clocking compared to 1546 MHz of Vega 10 is a convincing figure as a result of miniaturization of manufacturing process technology.

Jenomze VEGA 20 neni shrink VEGA 10. Ma 2* tolik HBM2 kontroleru, ma navic xGMI vystupy, misto PCIe3 ma PCIe4, navic ma podporu pro FP64, atd. Takze plocha VEGA 20 je logicky vetsi nez VEGA 10, pokud by byly na stejnem procesu.
