AMD Ryzen 7000 Zen4 Mobile Processors Revealed & R7 7730U Spotted

Leaks surface for AMD's next-gen Ryzen 7000 Zen4 architecture U, HS, and HX mobile processors.

Based on a Rumor

Update: AMD has already revealed Ryzen 7000 Series Mobile Processors, confirming rumors in this article that the Ryzen 7000 series will use different CPU / GPU microarchitectures in the same product lineup.

CES 2023 is rapidly approaching and AMD is expected to launch the new Zen4 based mobile processors in January during the event, however, not all next-gen Ryzen APUs will feature the RDNA 3 GPU architecture, some SKUs reportedly will use older RDNA 2 and even Vega iGPU architectures, in fact AMD confirmed some Ryzen 7000 mobile SKU will use a refreshed Zen3/Zen3+ and even Zen2 based CPUs.

Starting up with the Zen4 based mobile processors, a new report from IT Home details the APUs AMD is intending to unveil during CES 2023, including SKU names, CPU cores, and GPU cluster / compute units.

Zen4 U-Series Mobile Processors

TDP: 15-28W. Confirmed by AMD

The Zen4 U-Series APUs are intended for ultra-thin and light notebooks, coming in two APUs, the Ryzen 7 7740U utilizing 8 Zen4 based CPU cores with 12 RDNA 3 Core Clusters for the GPU, and Ryzen 7640U with 6 Zen4 CPU cores and 6 RDNA 3 Core Clusters GPU. The GPU cores is said to reach up to 2.6GHz with performance comparable to that of RX 570 levels.

Zen4 HS-Series Mobile Processors

TDP: 35W+ Confirmed by AMD

The HS mobile processors series are intended for gaming and creator notebooks, and just like the U-Series, the HS series will offer up to 8 Zen4 CPU Cores, however, they have a higher power consumption ceiling, presumably to allow for higher clocks i.e. better gaming performance.

Zen4 HX-Series Mobile Processors

Base TDP: 55W+ Confirmed by AMD

The HX mobile processors series are intended for performance high-end notebooks, with up to 16 Zen4 based CPU cores, and max out at 2 CU for the GPU (which seems polarizing to say the least), they have a base TDP of 55W and can consume up to 140W at max loads.

The Ryzen 7 7730U has 8 CPU cores / 20 Threads, a base clock frequency of 2GHz, and it is rumored to have 8 GPU core clusters with an RX Vega iGPU architecture.

Making Sense of AMD Naming Scheme

Taking all this information into consideration, here’s how AMD Ryzen 7000 mobile processor lineup is shaping up to be upon release, and how you can decipher which SKU is running which CPU and GPU architecture:
