Athlon & Ryzen 5 series for socket FT6, 2 RDNA 2 compute units, up to 32 GB LPDDR5, 4 PCIe Gen 3 lanes

AMD’s Mendocino APU specs that would cover the entry-level Athlon & Ryzen 5 laptop segment have been leaked on the Chiphell forums.

Leaked AMD Mendocino APU specs: up to 4 Zen 2 CPU cores, 2 RDNA 2 compute units, 32GB LPDDR5 memory and 4 PCIe Gen 3 lanes

Announced at Computex 2022, the AMD Mendocino APUs will be aimed at the entry-level thin-and-light laptop segment. The APU has also been featured in AYANEO’s upcoming Air Plus handheld game console to be launched later this year.

AMD Radeon RX 6000 and NVIDIA GeForce RTX 30 graphics card prices continue to improve with multiple GPUs available below MSRP

Unlike the other two APUs (Rembrandt & Barcelo), the AMD Ryzen 6000 “Mendocino” APUs will feature Zen 2 CPU and RDNA 2 GPU cores. These cores will be upgraded and optimized on the latest TSMC 6nm node and will offer up to 4 cores and 8 threads plus 4MB L3 cache.

This looks pretty much the same setup AMD used on their Van Gogh SOC that powers the Steam Deck (portable) console. But since the new APU lineup will be used in laptops, the chips will have a thermal and power advantage over Van Gogh. That said, these chips should still be super efficient and are mentioned to operate with 10+ hours of battery life (internally projected). Laptops will ship with an active cooling solution, as confirmed by Robert Hallock, as passive designs require more engineering and can increase product cost.

The new specifications reveal that AMD Mendocino APUs will be supported by the brand new “Sonoma Valley” platform based on the FT6 (BGA) socket. The GPU will be based on the RDNA 2 graphics architecture and will feature a single WGP (workgroup processor) for up to two compute units or a total of 128 stream processors. According to a report by Angstronomics, the RDNA 2 integrated graphics chip featured on Mendocino APUs will be codenamed Teal Grouper. The iGPU will feature 128KB of onboard graphics cache which should not be confused with Infinity Cache. So when it comes to architectural details, we look at:

  • Up to 4 Zen 2 CPU cores with 8 threads
  • Up to 2 RDNA 2 GPU cores with 128 SP
  • Up to 4 MB L2 cache
  • Up to 128 KB GPU cache
  • 2 channels 32-bit LPDDR5 (up to 32 GB of memory)
  • 4 PCIe Gen 3.0 lanes

Other specifications include two 32-bit memory channels supporting up to 32 GB of LPDDR5 memory, four display channels (1 eDP, 1DP and 2 Type-C outputs) and the latest VCN 3.0 engine with AV1 and VP9 decoding . As for I/O, the AMD Mendocino APUs will feature two USB 3.2 Gen 2 Type-C ports, 1 USB 3.2 Gen 2 Type-A port, 2 USB 2.0 ports, and a single USB 2.0 port for SBIO. I/O will also include 4 GPP PCIe Gen 3.0 lanes.

AMD Ryzen 6000 “Mendocino” APUs are set to launch in Q4 2022 and will be just months away from Ryzen 7000 “Dragon Range” processors and Zen 4 powered “Phoenix” APUs. It will be really interesting to see how the newcomer behaves in the market and the designs we will see with such a range of APUs. AMD has yet to confirm its SKUs for the new lineup, so they may hold another pre-launch event detailing the product stack, pricing, and specific products based on the new Mendocino Ryzen family of APUs. The lineup will target the entry-level laptop segment with pricing around $399 to $699 USD.
