AMD Ryzen AI Max 400 ‘Gorgon Halo’ packs up to 192GB of unified memory — refreshed APU uses Zen 5 and RDNA 3.5, and can clock up to 5.2 GHz

AMD is refreshing its stack of large SoCs, dubbed Ryzen AI Max, with new Gorgon Point chips. Codenamed Gorgon Halo, the Ryzen AI Max 400 range is a minor refresh to the Ryzen AI Max 300 ‘Strix Halo’ chips already available, similar to what we saw with Gorgon Point in laptops earlier this year. Gorgon Halo comes with one significant difference, however, which is space for up to 192GB of unified memory.Go deeper with TH Premium: CPURegardless, AMD has a lineup of three chips that should look very familiar if you’ve looked over the Strix Halo stack. All three chips use Zen 5 CPU cores and RDNA 3.5 GPU cores, alongside an XDNA 2 NPU. The flagship Ryzen AI Max+ Pro 495 comes with a minor clock speed bump of 100 MHz over the Ryzen AI Max+ 395, allowing it to boost to 5.2 GHz. Otherwise, you could scratch off the “4” and replace it with a “3,” at least based on the specs AMD has shared so far.Swipe to scroll horizontallyRow 0 - Cell 0 Cores / ThreadsArch (CPU / GPU)Boost ClockTotal CacheNPU TOPSiGPU (CUs)Unified memory (GPU memory)Max+ Pro 49516 / 32Zen 5 / RDNA 3.55.2 GHz80 MB55Radeon 8065S (40)Up to 192 GB (160 GB)Max Pro 49012 / 24Zen 5 / RDNA 3.55 GHz76 MB50Radeon 8050S (32)Up to 192 GB (160 GB)Max Pro 4858 / 16Zen 5 / RDNA 3.55 GHz40 MB50Radeon 8050S (32)Up to 192 GB (160 GB)These chips currently have a “Pro” tag, which means they’re targeting the commercial market. However, the slides below refer to the Ryzen AI Max 400 range more broadly. I asked AMD about this discrepancy, and a spokesperson sent the following: “AMD will be announcing the Ryzen AI Max PRO 400 Series, featuring AMD PRO technologies which deliver enterprise-grade security, manageability, and reliability.”So, I guess consumer Gorgon Halo is still up in the air. Maybe.Interestingly, AMD opted to stick with a GPU with 32 CUs (the Radeon 8050S) for the Ryzen AI Max Pro 490 and 485. Earlier this year, AMD refreshed the Ryzen AI Max 385 and 390 with 40 CUs, the same as the flagship, in the form of the Ryzen AI Max+ 388 and 392. Maybe we’ll see a refresh of the refreshed Gorgon Halo chips with 40 CUs down the line.Image 1 of 4(Image credit: AMD)Memory is the big upgrade here. Regardless of the GPU configuration, up to 160GB of unified memory can function as VRAM (32GB is reserved for the system). AMD says that much memory makes Ryzen AI Max 400 chips the first x86 client processors able to run a 300B+ parameter LLM. It wins in a category of one, however: Intel doesn’t make a large SoC like Gorgon Halo, and Apple uses the ARM ISA.Get Tom's Hardware's best news and in-depth reviews, straight to your inbox.AMD says Ryzen AI Max 400 chips are “coming soon,” but didn’t share any timeline beyond that, nor any partners for Gorgon Halo systems. Strix Halo, as a niche product, was only available in a handful of machines, such as the Framework Desktop, ROG Flow Z13, and GMKtec EVO-X2. There’s a good chance we’ll see a similarly conservative rollout of Gorgon Halo, as well.Despite not sharing any partners, AMD tells me that “several OEM partners have expressed excitement for the Ryzen AI Halo platform and the Ryzen AI Max Pro 400 series family of processors,” and that “systems will be announced from our partners starting in Q3 2026.”AMD Ryzen AI Halo starts at $3,999 — pre-orders in JuneThe only confirmed machine with Ryzen AI Max 400 so far is the Ryzen AI Halo, which is “coming soon” configured with the Ryzen AI Max+ Pro 495. Coming sooner is the Ryzen AI Halo box AMD revealed earlier this year with the Ryzen AI Max+ 395. AMD is opening up pre-orders in June, and it says the machine starts at $3,999.
