There ’s a shortage of GPUs as the demand for procreative AI , which is often prepare and run on GPUs , grows . Nvidia ’s intimately - performing chips arereportedlysold out until 2024 . The CEO of chipmaker TSMC was less affirmative recently , suggestingthat the shortage of GPUs from Nvidia — as well as from Nvidia ’s contender — could extend into 2025 .
To decrease their trust on GPUs , business firm that can afford it ( that is , tech giants ) are developing — and in some cases making available to customers — custom chips tailored for creating , iterating and productizing AI models . One of those firm is Amazon , which today atits annual AWS re : Invent conferenceunveiled the late generation of its chips for model training and inferencing ( i.e. running cultivate model ) .
The first of two , AWS Trainium2 , is designed to deliver up to 4x better performance and 2x well energy efficiency than the first - generation Trainium , unveiledin December 2020 , Amazon says . coiffure to be uncommitted in EC Trn2 instances in clusters of 16 chips in the AWS cloud , Tranium2 can scale up to 100,000 chips in AWS ’ EC2 UltraCluster product .
One hundred thousand Trainium splintering delivers 65 exaflops of compute , Amazon says — which work out to 650 teraflops per a unmarried chip . ( “ Exaflops ” and “ teraflops ” measure how many compute operations per moment a chip can perform . ) There ’s likely complicating factors making that back - of - the - napkin maths not needfully implausibly exact . But assuming a single Tranium2 chip can indeed deliver ~200 trillion floating point operations per second of performance , that puts itwellabove the capacity of Google’scustom AI trainingchipscirca 2017 .
Amazon tell that a bunch of 100,000 Trainium chips can train a 300 - billion parameter AI large spoken communication role model in hebdomad versus calendar month . ( “ Parameters ” are the parts of a example see from train data and essentially define the skill of the framework on a job , like generating textual matter or computer code . ) That ’s about 1.75 times the size of OpenAI’sGPT-3 , the herald to the text - generatingGPT-4 .
“ Silicon support every client work load , making it a decisive area of innovation for AWS , ” AWS compute and networking VP David Brown said in a press handout . “ [ W]ith the surge of pursuit in generative AI , Tranium2 will aid customers direct their ML example faster , at a lower cost , and with well energy efficiency . ”
Amazon did n’t say when Trainium2 example will become available to AWS customers , save “ sometime next year . ” Rest assured we ’ll keep eyes peel for more info .

The 2nd chip Amazon declare this morning , theArm - basedGraviton4 , is destine for inferencing . The fourth generation in Amazon ’s Graviton chip family ( as implied by the “ 4 ” tack on to “ Graviton ” ) , it ’s distinct from Amazon ’s other inferencing chip , Inferentia .
Amazon take Graviton4 provides up to 30 % effective compute execution , 50 % more cores and 75 % more retention bandwidth than one previous - propagation Graviton processor , Graviton3(but not the more recentGraviton3E ) , running on Amazon EC2 . In another upgrade from Graviton3 , all of Graviton4 ’s physical computer hardware interfaces are “ encrypted , ” Amazon say — on the face of it better batten down AI training workload and data for customers with rise encoding requirements . ( We ’ve ask Amazon about what “ code ” implies , exactly , and we ’ll update this piece once we hear back . )
“ Graviton4 cross the fourth generation we ’ve deliver in just five years and is the most potent and free energy - efficient chip we have ever built for a broad range of workload , ” Brown continued in a statement . “ By focusing our flake designs on real workloads that matter to customers , we ’re able to pitch the most sophisticated cloud infrastructure to them . ”
Graviton4 will be available in Amazon EC2 R8 g example , which are available in preview today with general availableness planned in the coming months .
