![]() ![]() On the side of raw computational power, AMD takes the lead with around 10.4 petaFLOPS of FP16/BF16 performance, approximately 1.3 times that of the H100 HGX, promising enhanced efficiency for complex calculations. The MI300X Platform comes with 1.5TB of HBM3 memory, which significantly overshadows the 640GB memory capacity of the H100 HGX, something every developer will be happy to have. AMD MI300 PerformanceĪMD has brought an interesting product to market with its Instinct MI300X Platform and is positioning it as a strong competitor to Nvidia’s hard-to-find H100 HGX. The power delivery system is ingeniously designed to accommodate different stacked dies and orientations, ensuring precise alignment and efficiency. The unique thermal architecture supports TDPs (Thermal Design Power) exceeding 550W, ensuring reliable performance even under demanding conditions. The MI300 family’s power management system is tailored to handle intensive computational workloads, with a design focus on power efficiency and heat extraction. The MI300 series employs a modular construction approach, allowing for flexible configurations and scalability.Īdvanced Power Management and Thermal Design This packaging method offers dense, power-efficient chiplet interconnects, enhancing overall system-level efficiency. 3.5D Hybrid Bond Packaging: A Leap in IntegrationĪ key highlight of the MI300 family is its 3.5D Hybrid Bond Packaging, significantly increasing compute and HBM (High Bandwidth Memory) within a package. The memory system is designed to maximize data-sharing efficiency and reduce latency, thanks to AMD’s innovative Infinity Cache and Infinity Fabric Interface. These units support a range of numerical formats like TF32 and FP8 and comply with OCP FP8 standards. Each Accelerator Complex Die (XCD) houses 38 CDNA 3 compute units, backed by a 4 MB shared L2 cache and optimized L1 cache for bytes/FLOP. The CDNA 3 compute unit in the MI300 series introduces notable enhancements. The memory system is equally impressive, with 48b/48b virtual/physical addressability, ensuring expansive memory support. This robust architecture supports simultaneous multithreading (SMT) and incorporates essential ISA updates, including BFLOAT16, VNNI, and AVX-512, with a 256b data path. Zen 4 CPU Complex Die (CCD) and EnhancementsĪt the heart of the MI300A APU lies the ‘Zen 4’ CPU Complex Die (CCD), featuring eight multithreaded AMD ‘Zen 4’ x86 cores, each boasting 1MB L2 cache and 32 MB of shared 元 cache. 8c 16t x86 CPU x 3 CCD’s (24 cores total).There is a lot of ground to cover here, and the nuance between the two is subtle but important. With its sophisticated design, the MI300 series promises to reshape the boundaries of computational power and efficiency. At least it looks like Zen 4 will be an exciting release when it finally rolls around on desktop, and that's without much information at all on the upgrades to the architecture itself.The AMD Instinct MI300 series introduces a new approach to accelerator architecture for AI, combining advanced technologies to drive progress in high-performance computing and artificial intelligence. Plenty to consider ahead of time then, and plenty more to learn about the next generation. The 5nm process is also said to be in high demand, which might not leave AMD with much wiggle room for multiple major product launches later in the year. Will it have enjoyed enough time in the sun by the time Zen 4 rolls around? The existing Ryzen 5000-series has had something of a slowed launch due to supply issues. When we can expect Zen 4 within AMD's desktop Ryzen chips depends on a few factors, but supply and demand is a vital consideration right now. From AMD's own roadmaps we know that it intends to release the Zen 4 architecture on the 5nm process node with EPYC Genoa chips ahead of 2022.ĪMD's current roadmaps were announced prior to the coronavirus pandemic, however, which could mean they're subject to change. We're still mostly in the dark about the next-generation of AMD Ryzen processors, though what we'd assume will bear the AMD Ryzen 6000 name. Intel is looking to shake up its processor footprint with its hybrid Alder Lake chips, which perhaps is even more reason for a new approach from the red team. Best CPU for gaming: the top chips from Intel and AMDīest graphics card: your perfect pixel-pusher awaitsīest SSD for gaming: get into the game ahead of the restĪMD has said that AM4 is nearing its expiration date, after five years in the field, and so it could be that an overhaul is on the way.
