AMD has launched its next-generation Epyc server processor: a high-performance, energy-efficient CPU that’s designed for cloud, undertaking, and synthetic intelligence workloads, the corporate introduced nowadays (October 10).
Built with the brand new Zen 5 core structure, the brand new fifth-generation AMD Epyc CPU options as much as 192 cores and can be utilized as a standalone chip for general-purpose workloads or AI inferencing. The {hardware} may also be paired with AI accelerators like AMD’s Instinct Series GPUs for greater AI fashions and programs, executives mentioned.
The new AMD Epyc 9005 collection processor, previously code-named Turin, supplies as much as 17% higher directions according to clock (IPC) for undertaking and cloud workloads and as much as 37% upper IPC for AI and high-performance computing workloads when in comparison to AMD’s Zen 4 chips that had been first presented two years in the past, the corporate mentioned.
With the discharge of the brand new processor, AMD will “once again take a huge generational leap in performance,” mentioned Forrest Norrod, govt vice chairman, and overall supervisor of AMD’s records heart answers industry Group, right through a pre-briefing with media and analysts.
At its Advancing AI tournament in San Francisco nowadays, the corporate additionally introduced new GPUs and knowledge heart networking answers, together with a brand new DPU and a NIC to hurry AI programs. The chipmaker reiterated its plan to free up a brand new GPU yearly, beginning with the AMD Instinct MI325X accelerator, which will probably be to be had right through the fourth quarter of this 12 months.
Analysts’ Take on AMD’s Announcements
Overall, analysts say AMD is doing what it must do to compete in opposition to opponents Intel and Nvidia – and it’s doing it rather well. In truth, whilst Intel nonetheless dominates, AMD executives mentioned they have got captured 34% marketplace percentage within the server CPU marketplace.
“AMD just continues to execute year after year. They’ve gotten to the point where it’s just improvement, improvement, improvement,” mentioned Jim McGregor, founder and primary analyst at Tirias Research.
Ian Cutress, leader analyst of More than Moore, agreed. “They’re hitting all the right corporate notes. They’re on track with everything they’ve talked about,” he mentioned. “This event is not only about their newest generation CPU, it’s their yearly cadence with the GPU, and they’re talking about networking and the synergy going in between. They’re basically saying, ‘We’re still putting one foot in front of the other, and it turns out, we’re pretty good at it.’”

Intel has accomplished a just right process with its roadmap and up to date free up of its Intel Xeon 6 CPUs and Gaudi 3 AI accelerator, however through shooting one-third of the knowledge heart CPU marketplace, AMD has momentum on its aspect, McGregor mentioned.
AMD may be doing neatly with its access into the GPU marketplace as an alternative choice to Nvidia’s GPUs, he mentioned. Many enterprises are simply beginning to discover how you can combine GPUs and AI workloads into its records facilities. There’s sturdy hobby in AMD as any other supply for GPUs, he mentioned.
“AMD has momentum. They’re still growing, and as long as they still continue to execute on their roadmap, they’re in a very good position,” McGregor mentioned.
Zen 5 Architecture
The corporate is the usage of two other Zen 5 core architectures for its fifth-generation CPUs. Zen 5, constructed the usage of the 4-nanometer production procedure, options as much as 128 cores and is constructed for functionality. Zen 5c, constructed the usage of 3nm and contours as much as 192 cores, is designed for potency and optimized for parallelization and throughput, McGregor famous.
It’s very just like the method Intel took with its Intel Xeon 6 effective cores (E-cores) and function cores (P-cores), the {hardware} analyst mentioned.
The reason why is that records heart operators’ wishes are converting as a result of they have got various kinds of workloads that experience distinctive necessities and require other processors.
“Both Intel and AMD have developed that performance and efficiency core strategy,” McGregor mentioned. “They realize they have to be more flexible because we’ve seen some hyperscalers develop their own processors for different applications. So this is kind of their response to the needs of not just the system vendors, but the end customers – the data centers.”
Staying On Message
AMD’s messaging at nowadays’s tournament is that it will possibly ship a complete infrastructure resolution that comes with CPUs, GPUs, DPUs, and networking, however the corporate must give a boost to its instrument, mentioned Peter Rutten, analysis vice chairman in IDC’s international infrastructure analysis group.
AMD nowadays mentioned it continues to spend money on and give a boost to its AMD ROCm instrument stack for development AI and HPC programs working on its GPUs. However, Nvidia is a long way forward with CUDA, Nvidia AI Enterprise, Nvidia NIM microservices, and Omniverse, McGregor mentioned.
“AMD is basically saying we, too, can deliver you the entire infrastructure and software. That’s good. That’s what customers want,” Rutten mentioned. “So you want those CPUs, GPUs, and fast networking. But I am worried about the actual developer story, the end user story. The software story is still getting short-changed and that should be a main focus.”
AMD’s GPU Roadmap and AI Networking Solutions
On the GPU entrance, the impending AMD Instinct MI325X will be offering 256GB of HBM3E reminiscence and 6TB/s of reminiscence bandwidth, which the corporate says is 1.8 instances extra capability and 1.thrice extra bandwidth than Nvidia’s H200 Tensor Core GPU.
AMD mentioned server distributors are anticipated to start delivery servers with the MI325X within the 2025 first quarter, together with Dell Technologies, Hewlett Packard Enterprise, Lenovo, and Supermicro, and others are anticipated to start delivery servers working the AMD.
After the MI325X, the corporate plans to free up the Instinct MI350 collection accelerator right through the second one part of 2025 and the MI400 collection in 2026.
The MI350 collection GPU will be offering 288GB of HBM3E reminiscence capability and can supply a 35x build up in AI inferencing functionality over AMD’s preliminary GPU – the MI300 collection accelerator, the corporate mentioned.
On the networking entrance, AMD introduced the brand new AMD Pensando Salina DPU, an accelerator that takes over records processing duties, equivalent to networking and safety, to disencumber CPU assets.
AMD’s new third-generation Pensando Salina DPU will supply two times the functionality, bandwidth, and scale as its earlier era and is designed for the front-end of an information heart community, which is able to give a boost to the functionality, potency, safety, and scalability for data-driven AI programs, the corporate mentioned.
For the again finish of the community, which manages records switch between accelerators and clusters, AMD introduced the Pensando Pollara 400 NIC, which the corporate claims would be the first Ultra Ethernet Consortium (UEC)-ready AI NIC, and can cut back latency, give a boost to throughput and save you congestion.
The DPU and NIC are anticipated to be to be had right through the primary part of 2025.
