New mobile Ryzen 9 CPUs have just made their first appearance in the benchmarks and could have brought us a dozen Zen 4s. (opens in new tab) Core to laptop for the first time. If it exists, it is. This is definitely a rumor. For now, the hardware is information from her leaker. Benchleaks Twitter account (opens in new tab).
[AOTS] Unknown CPU CPU: AMD Ryzen 9 7845HX (24T) GPU: Radeonhttps://t.co/PCW87b3xArNovember 14, 2022
The alleged AMD Ryzen 9 7845HX APU is benchmark list (opens in new tab) Ashes of the Singularity: Escalation is a strategy video game with a reputation for taxing processing cores. The rig appears to be using an integrated Radeon GPU, with 8GB of RAM, running the game at 1080p under DirectX 11, with graphics settings set to ‘crazy’. This is a level above “extreme”. It averaged just over 50fps.
With 12 cores and 24 threads (shown as 24 cores in benchmarks, just like the 12 core 7900X), this is the first Ryzen HX processor to feature 8 or more cores. HX processors will be added to AMD’s range in the Ryzen 5000 generation and will mean even better performance than the ‘regular’ H-series, which are high-performance mobile APUs. Mainstream mobile APUs have a U at the end of their name, while M-series chips are for low-power mobile.
video cards This means the Ryzen 9 7845HX is a repurposed desktop model, and we’re speculating that it could indeed be a member of the Dragon Range. (opens in new tab) The family made the announcement in June. This makes it one of the first mobile chips identified using AMD’s new naming convention. (opens in new tab): The leading 7 means 2022, the 8 is that market segment, and confusingly could mean either Ryzen 7 or 9 (although the CPU names are pretty clear). The 4 is for the Zen 4 architecture, and the 5 means it’s a higher-end model in its segment. Lower class chips are filled with 0.
Most other benchmarks on this site show previous generation AMD HX chips running discrete GPUs, using DirectX 12 or Vulkan, or with graphics options set completely differently so it’s hard to find a direct comparison. For example, a 12-core Ryzen 9 5900X with integrated GPU under Vulkan and with 32 GB of RAM managed an average score of 112 FPS. This suggests that DirectX 11 isn’t the best API to really showcase the new chip’s capabilities.
