This year’s September Apple event has been relatively unusual, not only because of the pandemic and online-only nature of the show, but also because amongst the new hardware releases there’s been an evident lack of a new iPhone at this point in time. Apple however didn’t disappoint, and managed to showcase brand-new iPads and Apple Watches. Amongst the new tablet line-up, we find the new 8th generation iPad which sees an upgrade in its computing capabilities with the new A12 chip, and the newest iPad Air which sees a total redesign, adopting the design queues of the iPad Pro siblings, and also for the first time introducing the new Apple A14 chipset – the industry’s first 5nm processor.

NVIDIA Ampere Unleashed: NVIDIA Announces New GPU Architecture, A100 GPU, and Accelerator - AnandTech
While NVIDIA’s usual presentation efforts for the year were dashed by the current coronavirus outbreak, the company’s march towards developing and releasing newer products has continued unabated. To that end, at today’s now digital GPU Technology Conference 2020 keynote, the company and its CEO Jensen Huang are taking to the virtual stage to announce NVIDIA’s next-generation GPU architecture, Ampere, and the first products that will be using it. Like the Volta reveal 3 years ago – and is now traditional for NVIDIA GTC reveals – today’s focus is on the very high end of the market. In 2017 NVIDIA launched the Volta-based GV100 GPU, and with it the V100 accelerator. V100 was a massive success for the company, greatly expanding their datacenter business on the back of the Volta architecture’s novel tensor cores and sheer brute force that can only be provided by a 800mm2+ GPU. Now in 2020, the company is looking to continue that growth with Volta’s successor, the Ampere architecture. Now a much more secretive company than they once were, NVIDIA has been holding its future GPU roadmap close to its chest. While the Ampere codename (among others) has been floating around for quite some time now, it’s only this morning that we’re finally getting confirmation that Ampere is in, as well as our first details on the architecture. Due to the nature of NVIDIA’s digital presentation – as well as the limited information given in NVIDIA’s press pre-briefings – we don’t have all of the details on Ampere quite yet. However for this morning at least, NVIDIA is touching upon the highlights of the architecture for its datacenter compute and AI customers, and what major innovations Ampere is bringing to help with their workloads. Kicking things off for the Ampere family is the A100. Officially, this is the name of both the GPU and the accelerator incorporating it; and at least for the moment they’re both one in the same, since there is only the single accelerator using the GPU.
