AMD Talks EPYC Bergamo ‘Zen 4C’ CPUs & Instinct MI300 APUs For Next-Gen Hyperscale Data Centers
Mark starts off by talking about the immediate follow-up to their recently launched 4th Gen EPYC CPUs codenamed Genoa, the 4th Gen Bergamo lineup. The AMD EPYC Bergamo lineup is optimized for compute density and is positioned against Arm. It is stated that AMD’s EPYC Bergamo CPUs will be arriving in the first half of 2023 and will use the same code as Genoa and also run like Genoa but the code is half the size of Genoa. The CPUs are specifically mentioned to compete against the likes of AWS’s Graviton CPUs and other ARM-based solutions where peak frequency isn’t a requirement but throughput through the number of cores is. One workload example for Bergamo would be Java where the extra cores can definitely come in handy. Following Bergamo will be the TCO-optimized Siena lineup for the SP6 platform which will play a crucial role in expanding AMD’s TAM growth in the server segment. Mark Papermaster (AMD CTO and Executive VP of Technology & Engineering) The AMD Genoa-X CPUs are expected to hit production by end of Q3 / early Q1 2023 and will launch around mid of 2023. They will feature a similar design methodology as the Milan-X chips with 3D V-Cache as ‘Large L3’ is a highlighted feature of the lineup. While Milan-X features up to 768 MB of L3 cache, Genoa-X CPUs will feature over 1 GB of L3 cache while rocking the same 96 cores based on the Zen 4 design. So in total, SP5 will end up with three EPYC families. And so one, we have the – from top to bottom of stack has incredible coverage now with the kind of granularity that our customers need to really cover hyperscale through enterprise, and we are adding in first half of this year, what we call Bergamo, which will be with our Zen 4c, we increased staffing to our CPU team, and we added a version of Zen 4. It’s still Zen 4. It runs a code just like Genoa, but it’s half the size. And that competes head-to-head with Graviton and ARM-based solutions where you don’t need the peak frequency. You’re running workloads like Java workloads, throughput workloads that don’t have to run peak frequency, but you need a lot of cores. So we’re adding that in first half of ‘23. And then later in 2023, we’re adding the Sienna which is a variant targeted to telecom space. So we’re really, really excited about our TAM growth in server. Mark Papermaster (AMD CTO and Executive VP of Technology & Engineering) Lastly, we have a confirmation from Mark that AMD already has its next-generation Instinct MI300 APU which utilizes a combination of CDNA 3 GPU Cores and Zen 4 CPU cores packaged alongside a handsome amount of HBM3 memory is back in the labs and crunching through various tests. Mark Papermaster (AMD CTO and Executive VP of Technology & Engineering) This behemoth of a chip is expected to launch by 2023 and will utilize a 5nm process node and run on the same SP5 socket platform as the 4th Gen EPYC CPUs. The Instinct MI300 accelerator will rock a unified memory APU architecture and new Math Formats, allowing for a 5x performance per watt uplift over CDNA 2 which is massive. AMD definitely has a lot planned out for 2023 to accelerate its server growth and TAM. The chip maker unveiled its latest roadmap during its Financial Analyst Day which goes one step ahead & talks about future Zen 5 core lineups too, detailed here.
