AMD Ryzen 7 8840U APU Benched in GPD Win Max 2 Handheld
GPD has disclosed to ITHome that a specification refresh of its Win Max 2 handheld/mini-laptop gaming PC is incoming—this model debuted last year with Ryzen 7040 "Phoenix" APUs sitting in the driver's seat. A company representative provided a sneak peek of an upgraded device that sports a Team Red Ryzen 8040 series "Hawk Point" mobile processor, and a larger pool of system memory (32 GB versus the 2023 model's 16 GB). The refreshed GPD Win Max 2's Ryzen 7 8840U APU was compared to the predecessor's Ryzen 7 7840U in CPU-Z benchmarks (standard and AX-512)—the results demonstrate a very slight difference in performance between generations.
The 8040 and 7040 APUs share the same "Phoenix" basic CPU design (8-cores + 16-threads) based on the prevalent "Zen 4" microarchitecture, plus an integration of AMD's Radeon 780M GPU. The former's main upgrade lies in its AI-crunching capabilities—a deployment of Team Red's XDNA AI engine. Ryzen 8040's: "NPU performance has been increased to 16 TOPS, compared to 10 TOPS of the NPU on the 'Phoenix' silicon. AMD is taking a whole-of-silicon approach to AI acceleration, which includes not just the NPU, but also the 'Zen 4' CPU cores that support the AVX-512 VNNI instruction set that's relevant to AI; and the iGPU based on the RDNA 3 graphics architecture, with each of its compute unit featuring two AI accelerators, components that make the SIMD cores crunch matrix math. The whole-of-silicon performance figures for "Phoenix" is 33 TOPS; while 'Hawk Point' boasts of 39 TOPS. In benchmarks by AMD, 'Hawk Point' is shown delivering a 40% improvement in vision models, and Llama 2, over the Ryzen 7040 "Phoenix" series."ITHome reported on the reasoning behind system memory upgrades for the manufacturer's 2024 devices: "GPD officials said that 16 GB of memory will be the minimum requirement for AI PCs, so subsequent AI PCs with 32 GB of memory should be standard, and AI PCs with 64 GB of memory will also be common."GPD's entry-point recommendation aligns with recent Microsoft advisements.

And even single-die Ryzens should have 32 MB of L3 cache.
R5 8540U = 2(Zen 4) + 4(Zen 4c)
R3 8440U = 1(Zen 4) + 3(Zen 4c)
8840U is basically the 7840U (or a lower-powered 7840HS/7940HS) but with a better NPU for AI.
The fresh chips are the Ryzen 3 and 5 models that are mixed with Zen 4c cores.
Also with the new SteamOS 3.6/Mesa 24 tests the Steam Deck OLED comes back on top for low-TDP usage:
It will be interesting to test the Legion Go with newer Radeon drivers in a 4C/8T/12CU configuration (since it doesn't seem to be possible to disable cores with the current ROG Ally BIOS yet). I'm already getting better battery life than the ROG Ally in the same configuration with current drivers.
